2008 Physical Activity Guidelines for Americans

The 2008 Physical Activity Guidelines for Americans (USDHHS, 2008a) provide specific clinical recommendations that address and promote physical activity and are applicable for ages 6 and older. Recommendations include:

• Children and adolescents should strive for 60 minutes of physical activity daily; the minutes do not necessarily need to be contiguous.

• Physical activity should be of moderate to vigorous levels.

• Physical activity should include each of the following on 3 or more days per week:

Aerobic activity for cardiovascular and respiratory fitness

Resistance activities for muscular strength

Weight loading for bone strength

• Physical activity should be enjoyable to the child/adolescent and developmentally appropriate.

• In becoming more physically active, a child or adolescent who was previously inactive should increase time and intensity gradually.

• Any level of physical activity is better than none at all.

A full summary of the guidelines and other online resources can be accessed over the Internet. (See Resource list.)

Healthy People 2010 and 2020

Healthy People 2010 and the newer Healthy People 2020 are broad-based collaborative efforts to address 10 high-priority public health issues; physical activity is one of these indicators. The wording of the Healthy People 2020 document refers clinicians to the 2008 Physical Activity Guidelines for Americans for specific clinical intervention recommendations. The following objectives relate to physical activity and fitness in children/adolescents (USDHHS, 2009):

American Academy of Pediatrics Guidelines

The American Academy of Pediatrics (AAP) endorses the 2008 Physical Activity Guidelines for Americans. The organization’s own policy statement includes the following recommendations (AAP, 2010a):

Health Conditions Benefiting From Physical Activity

For some individuals, regular physical activity is an even more crucial component of preventing and treating chronic health problems. The following highlight the major findings of the effect and benefits of physical activity on several important health conditions.

The increase in global chronic disease rates caused by poor diet and inactivity is a major public health concern of the WHO, which reports that more than 42 million children younger than 5 years are obese (WHO, 2010b). In 2004, the WHO developed a population-wide global strategy on diet, physical activity, and health and later published a framework for member countries to implement and monitor their progress to increase physical activity (WHO, 2004). The U.S. has the highest rate of obesity in males 15 years and older of all member WHO countries (WHO, 2010c).

Obesity in childhood or adolescence greatly increases the risk that the person will remain obese as an adult. A study in England showed that the propensity to gain weight was related to lower self-esteem in childhood. This weight gain was more likely to occur in children who felt less in control of their lives and who worried (Ternouth et al, 2009). Studies have also demonstrated that a lower body satisfaction in adolescents is related to lower physical activity and more hours of TV watching (Neumark-Sztainer et al, 2004).

• Hypertension. For hypertensive youth, regular aerobic activity helps reduce blood pressure. Studies have shown that the most beneficial type of activity to lower blood pressure is aerobic exercise at a level that improves one’s aerobic fitness for a minimum of 30 minutes, 3 days per week. Resistance training coupled with aerobic exercise has also been shown to be beneficial in terms of maintaining blood pressure within the normal range once the hypertension is resolved (AAP, 2010a; Strong et al, 2005).

• Metabolic syndrome. For individuals with metabolic syndrome, engaging in moderate to vigorous regular physical activity has the positive effects of increasing high-density lipoproteins (HDLs) and reducing triglycerides and insulin levels. Exercise has not been shown to reduce total cholesterol or low-density lipoproteins (LDLs). In the studies reviewed by Strong and colleagues, 40 minutes of moderate to vigorous exercise on 5 days of the week is required to have measurable effects on reducing lipids and insulin level (Strong et al, 2005).

• Reactive airway disease. Children with asthma who do regular aerobic physical activity have been shown to experience improved aerobic and anaerobic fitness. There is no evidence that physical activity improves pulmonary function status (Pianosi and Davis, 2004).

• Special needs children. Children and youth with disabilities require special focus in order to ensure that they have access to the means to be physically active and at levels that offer health benefits. Due to higher levels of physical inactivity, youth with physical disabilities experience poorer cardiovascular health, lower levels of muscular endurance and higher obesity levels than do children without disabilities (Murphy et al, 2008). Benefits of physical activity for children and adolescents with disabilities are physiological and psychological—improved self-esteem, greater independence, and improved social skills. Recommendations for providers to promote physical activities for children having special needs include (Murphy et al, 2008):

Being aware that participation in sports and being physically active is important for children with disabilities

Performing preparticipation examinations to identify the individual’s strengths as well as areas where adaptation is required

Communicating with PE teachers, coaches, and trainers to ensure that adaptations are available

Being aware of resources for youth and families that advocate for sports inclusion for children with special health care needs

Motivation and Barriers to Maintaining Physical Activity

A number of factors affect an individual’s motivation to become and/or maintain a physically active lifestyle. Physical activity, like any behavior, operates on a socioecological model. Table 13-1 describes the different levels of influence a clinician can engage in to promote physical activity. The effect of socioeconomics, race/ethnicity, and culture is important to be aware of in order to effectively and equitably address the barriers and resources for physical activity (Brennan Ramirez et al, 2008). A midcourse review of Healthy People 2010 (USDHHS, 2006) describes some local, state, and federal level community health approaches (and the extent of their effectiveness) to decreasing disparities.

TABLE 13-1 Socioecological Model for Effective Promotion of Physical Activity by Providers

Level of Intervention	Examples
Individual Level
Address physical activity during patient visits.	• Discuss physical activity recommendations as anticipatory guidance during well-child examinations and as part of healthy lifestyle counseling in obesity prevention and treatment. Assess physical activity level as “vital sign” at all patient visits. • Use motivational interviewing techniques in patient visits to address and promote behavioral change for increasing physical activity. Base intervention on “stages of change” theory as a collaborative patient/provider model. See Chapter 9 for a discussion of these techniques.
Organizational Level
Promote activities on an institutional level that encourage physical activity.	• Promote activities that encourage organizational physical activity promotion, for example: School programs such as walk or bike to school days Screen time awareness week Intramural programs Advising child care centers about ways to increase physical activity for children and staff Advising schools and parents about importance of recess and physical education Encouraging schools to not withhold recess as a punishment for misbehavior
Community Level
Encourage local projects that promote physical activity.	• Promote activities that help communities structure public space and promote physical activity. Ensure safe and easily accessible park and playground space. Ensure affordable organized activities (e.g., scholarships to pay for team sports or after-school activities for low-income youth). Advocate for bike lanes and walking trails in the community. Advocate for vehicular speed control along major routes to schools to encourage walking/cycling safety (see CDC, Kids Walk-to-School website). Promote programs that teach bike safety and distribute low-cost helmets. Advocate for keeping school buildings open after school for supervised physical activities.
Public Policy Level
Involve public bodies (e.g., school boards, local/state government) to ensure laws and policies promote physical activity.	• Advocate for changes in public policy by: Addressing hearings on importance of maintaining physical education in schools Addressing zoning issues to maintain or increase green spaces such as parks, bike trails, walking trails Working with planners to ensure that communities are designed to promote family friendly physical activity (e.g., adequate sidewalks and crosswalks, residential areas within waking distance to neighborhood schools, adequate lighting at playfields and parks)

CDC, Centers for Disease Control and Prevention.

Counseling Families about Organized Sports for their Children

Being physically active is best achieved as a lifelong habit when it is encouraged from infancy. Guidance to parents and other caregivers is important so that youth can benefit and thrive from athletic endeavors without experiencing psychological or physical harm.

More and more, organized sports are taking the place of children’s casual and informal play times (AAP, 2007a). It is now more common to see preschool sports training and teams. When done in an age or developmentally appropriate manner, these activities allow children to benefit from the safety of coaching, proper equipment use and playing facilities, and adult guidance.

Table 13-2 provides guidance for a developmentally appropriate approach to sports activities. The following are some basic concepts to keep in mind when counseling parents, guardians, and youth about athletic participation (AAP, 2007a):

• Regardless of age, the goals of sports participation should be to have fun, to develop skills, and to form a foundation for lifelong fitness.

The clinician should always be alert for youth athletes who appear to be stressed or pressured by adults (parents, coaches) to achieve a certain level of competition. Explore motivation for participation because there may be pressure to perform in order to get recognized by professional scouts, receive athletic scholarships, or make a varsity team. One study (Savage et al, 2009) showed that perceived encouragement from fathers (but not mothers) for physical activity was a significant factor in mid-adolescence.

• For the young child entering sports (preschool through school-age), the goals should be healthy activity, learning basic skills, and rules of the game. The skills of several children of the same age can be widely discrepant.

Up to the age of puberty, any organized athletic activities should complement rather than replace less structured physical activity that focuses on fun and playfulness (e.g., free play, “pick up” games, and school PE).

In general, preschool children have limited attention spans and can be distractible. It is advised that structured exercise sessions be short (no longer than 15 to 20 minutes), that there be 30 minutes of free play, and that activities be playful, creative, and allow exploration of movement (AAP, 2007a).

• About 7 years old children are generally ready for organized noncontact sports, but involvement should be guided by the individual child’s cognitive and motor development and interest. It is important to keep the focus on participation rather than on winning.

Even with team sports for young children (up through about the age of 10 years), it is advisable to maintain enthusiasm through noncompetitive means (praise, fun experiences, team and leadership building activities). Such things as score-keeping, trophies for performance, awards for “best player,” although well intentioned, may be detrimental to positive self-esteem and one’s future interest in sports for this age group.

Clinicians are in an excellent position to be sure parents and coaches for the younger child understand the developmental level of this age group.

• About age 10, children become more ready to master complex skills such as rules and strategies for competitive sports. It should always be a goal to keep the focus on skill development, personal improvement, and individual positive strides, rather than on competition, embarrassment, or unnecessary regimentation or stress.

• The child who is an exceptional athlete may still have maturation difficulties in social and psychological areas. Finding a balance in supporting the development of an athletically gifted child can be difficult given the stress this child may face in the competitive arena.

• Parents and coaches should always role model best athletic practices for injury prevention and sportsmanship (e.g., wear bicycle helmets when riding with their children, pre- and postgame handshakes with opposing team members).

• Children with handicaps should be encouraged to participate in sports that best fit their abilities and that are safe.

• Children with academic problems should not be denied participation in sports. Studies have concluded that an increase in PE time at school does not negatively affect academics (CDC, 2010a). Sports can be the best arena for boosting self-esteem for the child who does not experience success in the classroom. Helping the child find a balance between academic work and sports participation is essential.

• Boys and girls can play together, especially in the prepubertal years. Differences in height and weight can make it unsafe for smaller girls to compete in contact sports with boys after puberty.

• Children should not focus on sports specialization until puberty (Brenner, 2007). Prior to that age, it is recommended that children play varied sports, enabling them to maintain their energy and interest for a longer time.

• Sports specialization at a young age and/or overtraining can cause overuse injuries (microtrauma damage to bone, muscle, or tendons that occurs from repetitive overuse without sufficient rest and healing time) and/or “burnout” (symptoms include repeated overuse and other injuries, general fatigue, psychological stress, and decreased athletic performance; participation becomes a chore; and a lack of joy and enthusiasm are expressed) (Metzl, 2003; Smith and Link, 2010).

• Suggestions for preventing overtraining and burnout (Brenner, 2007) include:

Keep practices interesting, varied, and fun.

Take 1 or 2 days a week off from organized activity, allowing the body to rest (okay for the athlete to do recreational physical activity if desired on the days off).

Schedule breaks from training every 2 to 3 months (after a season is completed). During this time the athlete can cross-train or participate in other physical activity to stay in shape.

Discourage competing in multiple sports during the same season.

Adhere to sport-specific guidelines (e.g., number of pitches per game for baseball/softball, safe increases in distance training for runners).

TABLE 13-2 Appropriate Fitness Activities by Age Group

Strength Training

Strength training refers to the use of resistance methods (such as free weights, weight machines, elastic bands, or body’s weight) to increase muscular strength and endurance. Strength training can be used for several reasons: to enhance performance in a particular sport, as a component of rehabilitation after some injuries, and, for some, to enhance muscle mass for appearance.

The safety of strength training for children and young adolescents had been questioned in the past due to possible detrimental effects of such training on immature skeletons. The concern was that the lack of sufficient circulating androgens (needed for muscular strength and mass) could lead to damage of open growth plates, causing premature closure of epiphyses (Young and Metzi, 2010). However, more current consensus is that strength training is advantageous, even for young athletes, provided that it is done in a safe and supervised manner (AAP, 2008a; Faigenbaum and Micheli, 2007). Strength training must be differentiated from weight training, weight lifting, powerlifting, or bodybuilding, which are still not recommended for prepubescent children and young adolescents due to concerns of safety on immature skeletons (AAP, 2008a; Young and Metzi, 2010).

Benefits of strength training include improved cardiovascular fitness, strength, flexibility, body composition, bone mineral density, blood lipid profile, and mental health. Additionally, strength training is an important component to weight management programs because it produces metabolic rate increases without having to do high-impact activities (AAP, 2008a). Additionally, as a component of a well-rounded conditioning program, it has been shown to reduce blood pressure in hypertensive youth; when included in the preseason conditioning and training program for many sports, it correlates with a decrease in sports injuries (Young and Metzi, 2010).

Strength training for young athletes needs to be supervised; there are fewer injuries from strength training than from the sports themselves (notably lower back strains). Box 13-1 lists general guidelines for strength training by the preadolescent.

BOX 13-1 Safe Practices for Strength Training for Youth Athletes

• Children who are ready to play in organized sports (e.g., Little League baseball, soccer) are ready to participate in some form of strength-related activity, even if it consists of only push-ups and sit-ups for young children.

• Strength training should be only one component of a well-rounded fitness program.

• Prior to starting a formal strength training program, the child should ideally have a physical examination, especially if he or she has any known or suspected health condition.

• Athletes and families should be advised of the dangers of using performance-enhancing drugs to increase strength and muscle mass.

• Training should be done under the supervision of a coach or trainer who is familiar with the appropriate training regimens for different age groups and knowledgeable about the equipment and its use.

Training should be progressive—start at zero or low weight with few repetitions; when able to perform sets of 6 to 15 repetitions with ease, gradually increase weight increments by 5% to 10%. Avoid maximal lift weight and powerlifting until Tanner stage 5 has been reached to avoid potential injury to long bones, growth plates, and back (Hatfield, 2010).

Begin with one set each of upper and lower body exercises to allow focus on major muscle groups.

Train no more than two or three times a week, on nonconsecutive days to allow for recovery and to produce the greatest gains in strength building.

Emphasize proper technique and safety rather than amount of weight lifted.

• Exercises should be balanced among all muscle groups, including core muscles.

• Ensure adequate fluid intake during training.

• All training sessions should begin and end with a period of warm-up/cool-down exercises that include stretching and dynamic movement, such as a slow jog, jumping, or skipping.

Restrictions on who can safely do strength training include youth with severe hypertension; anyone who is receiving chemotherapy with anthracyclines or any other potentially cardiotoxic medication; youth with some forms of cardiomyopathy (particularly hypertrophic cardiomyopathy); individuals with moderate to severe pulmonary hypertension (at risk for acute decompensation with a sudden change in hemodynamics); and those with Marfan syndrome with a dilated aortic root. Youth with seizure disorders should be withheld from strength training programs until clearance is obtained from a neurologist (AAP, 2008a).

Preseason Conditioning and Injury Prevention

A variety of strategies can be used to reduce the incidence and severity of injuries and heat-related illnesses and dehydration (see also Chapter 39). Some of the more typical injury conditions that can be avoided with simple prevention strategies are included in Table 13-3. Readiness can be addressed from two perspectives, developmental readiness and preseason conditioning readiness. Developmental readiness has been previously discussed.

TABLE 13-3 Common Injuries and Prevention Strategies

Preseason conditioning (examples: preparatory muscle conditioning and plyometric training [exercises that combine strength with speed of movement to enhance power, such as hops and jumps; the central nervous system becomes conditioned to react quickly to stretching and shortening]) is a method for decreasing overall injuries. One study showed a 51% decrease in knee and ankle injury incidence and the severity of injuries due to conditioning (Olsen et al, 2005). Conditioning also lessens overuse injuries (stress fractures, bursitis, tendinopathies) and the amount of time needed for rehabilitation, helps strengthen bone, facilitates weight control, enables the nervous system to react more quickly to the stretch-shortening cycle, improves balance and coordination, adds muscle mass, and improves performance. When started in players as young as 10 to 12 years old, warm-up programs help them establish overall motion patterns. Such conditioning is not sport specific, but entails activities geared toward improving strength, flexibility, and endurance; it is not to be confused with weight lifting or bodybuilding. Coaches and fitness instructors should be certified and be knowledgeable about age-specific training techniques and safety; adult training techniques should never be applied to children.

Use of Helmets for Cycling and Winter Sports

More children and adolescents visit emergency departments for cycling injuries than for any other recreational activity (U.S. Consumer Product Safety Commission [USCPSC], 2006). Two thirds of all brain injury fatalities result from such incidences (American Association of Neurological Surgeons, 2010). Ninety-one percent of bicyclists who died in a crash were not wearing a helmet (Insurance Institute for Highway Safety, 2008). Despite preventing approximately 85% of head injuries and 88% of brain trauma, only 45% of children 5 to 14 years old reported wearing a helmet in states with helmet laws, whereas 39% did so in states without such laws (Safe Kids USA, 2004; USCPSC, 2006). Valuable information about bike safety for children is available from the National Highway Traffic Safety Administration. Proper use starts with proper fitting.

• Try on several sizes and models to find the best fit that:

Places the helmet low on the forehead

Positions the brim so that it is parallel to the ground when the head is upright (child should be able to see the brim when looking up). This may require removing or installing inside pads to enable a snug fit, or adjusting sizing ring

Securely fastens the chin strap to the point where the helmet will not shift over the eyes, rock side to side, or come off when the child shakes the head

• Helmets should carry a USCPSC sticker.

• A helmet should be thrown away if it has been involved in any substantial blow that resulted in marks on the outer surface; do not purchase secondhand helmets.

• Replace helmets every 5 years or sooner, depending on the manufacturer’s recommendations.

• Children are more likely to wear helmets if a parental rule exists about its unconditional use, if parents wear helmets during cycling activities, and if there is a mandatory state helmet law, although these usually only apply to children younger than 16 years.

The efficacy of helmet use for young recreational skiers is controversial. A USCPSC (1999) study estimated that 44% of head injuries (53% for children younger than age 15) and 11 deaths could have been prevented by the use of helmets. The USCPSC study also referred to a Swedish study that found a 50% decrease in head injuries in those using helmets versus those without. Shealy’s (2010) study of head injuries on ski slopes, though, found an increase in injuries when a helmet was used. He conjectured that the use of a helmet was seen as a license to ski faster or take chances (like skiing among trees). The helmeted skiers also suffered more serious head injuries than those unhelmeted. At a speed in the range of 25 to 40 mph, whether one is wearing a helmet or not, a helmet is not viewed by Shealy as providing the protection needed to prevent serious head trauma. Helmets are highly advocated by the National Ski Areas Association and such winter sports programs as Lids on Kids.

Calories

Depending on the sport, calorie requirements for active teenagers exceed baseline needs by 1500 to 3000 calories. The recommended diet for the athlete is the same as for all people. The daily energy and micronutrient requirements for athletes at various ages can be found in Chapter 10.

Carbohydrates

Short-term, high-intensity activities (e.g., high jumping or diving) involve using anaerobic fuel sources, whereas longer-term activities involve use of aerobic sources (e.g., running or cross-country skiing). Carbohydrates are used in both anaerobic and aerobic metabolic states, but fats and proteins are used only aerobically. Complex carbohydrates (e.g., fruits, nuts, cereals, grains, pasta, dried beans) are preferable to simple carbohydrates (such as cookies, sugary foods, ice cream, some crackers). Simple carbohydrates should not exceed 10% of daily carbohydrate intake (Nemet and Eliakim, 2009). Complex carbohydrates, although providing readily available energy, do not cause the rapid rise in blood glucose levels with resultant insulin rebound that simple carbohydrates do. Hypoglycemia can result from insulin excess, which is counterproductive to the energy needed in the sport.

In general, carbohydrates will be most effectively converted into the needed energy if they are consumed several hours before the athletic event or practice. Approximately 300 g of carbohydrate-rich food, 2 to 3 hours prior to exercise is recommended. Ingesting carbohydrates just before activities has no effect on performance. Carbohydrate loading has not been studied in children and is generally not recommended. If an athlete is participating in long-endurance events, carbohydrate loading may be appropriate once or twice during an entire season, and only with the guidance of a coach, trainer, or nutritionist with experience in the age group (Baker, 2009). Carbohydrate intake (30 g/hr) during physical activity lasting more than 1 hour improves performance. After competition, carbohydrate intake is again important to improve muscle glycogen resynthesis, which is most rapid in the first few hours after exercise. During the 2 hours after performance, consuming carbohydrates (approximately 75 g) in the first 30 minutes and 100 g every 60 minutes will achieve this resynthesis. This can be in the form of snacks or liquids.

Protein

Protein provides energy when stored glycogen and fat are depleted during endurance exercise. Amino acid/protein supplements do not increase muscle mass or decrease body fat. Hypercalciuria with calcium loss and dehydration can occur if protein intake is too high because the excess nitrogen, and hence water, is excreted. Additionally, eating too much protein may lead to an underconsumption of adequate carbohydrates and fats, causing the excess protein to be stored as fat.

Fats

Dietary fats serve as high-calorie sources of energy. Emphasis should be on polyunsaturated fats, with saturated fats not exceeding about 10% of the total fat calories. Athletes who are restricting nutritional intake of fats may under-consume them, thus becoming deficient in fat-soluble vitamins (A, D, E, and K).

Intentional Weight Loss

Weight loss by adolescent athletes can be a dangerous practice. Wrestlers may try to lose weight to be eligible to compete in a lower weight class; runners sometimes vomit to run lighter; and female gymnasts may practice significant nutritional control to maintain weight and size. Dancers, divers, figure skaters, and cheerleaders also control weight for appearance advantages. Bodybuilders, rowers, distance runners, and swimmers often try to control their weight. Starvation can lead to suppressed growth hormones, can interfere with pubertal gonadal hormone changes, and may result in eating disorders. Nutritional counseling is essential, including a reminder that muscle weighs more than fat, and that during adolescent growth, weight gain is normal.

Wrestlers often engage in repeated bouts of excessive weight loss or weight cycling. Such transient weight cycling can deplete electrolytes, decrease glycogen stores, affect hormones, diminish nutritional status, impair mental and academic performance, reduce immune function, alter hormonal status, and lead to pulmonary emboli and pancreatitis. This temporary weight cycling may adversely affect or alter growth patterns in weight and height and performance (Housh and Johnson, 2007). This practice is to be discouraged because of the risk for long-term dysfunctional eating and short-term effects discussed earlier. Measurements of body composition before and during the wrestling season can help coaches and parents stay alert to risky behavior; any planned weight loss should involve appropriate dietary changes and exercise training. Wrestlers, coaches, and parents may elect to sign a contract requiring that the child eat three meals a day, that fluid be available at all times, and that no artificial means be used to remove fluids from the body (e.g., sauna or sweatsuit, laxatives, diuretics, diet pills, licit or illicit drugs, nicotine, prolonged fasting, over-exercising, or vomiting).

Sports Drinks

Sports drinks are among the most popular supplements used by youth athletes. More than 7 million adolescents in the U.S. are estimated to consume them (Nemet and Eliakim, 2009). Some may contain dangerously high levels of caffeine and should be discouraged. See the discussion later in this chapter about performance-enhancing drugs and “energy drinks.” The ingredients in these widely available drinks contain 6% to 8% carbohydrates (glucose, sucrose, and fructose). Some formulations also contain complex carbohydrates (e.g., maltodextrin) and amino acids. Other ingredients maintain fluid electrolyte balance (sodium, potassium, and magnesium). In studies, young athletes have reported positive effects after consuming these drinks at recovery; however, no objective effect on physical performance or recovery has been found. There may be a place for electrolyte replacement drinks in high-endurance athletes. However, there is no sufficient evidence to show that carbohydrates or electrolytes in these beverages are needed in a typically active young athlete who maintains a balanced diet (Nemet and Eliakim, 2009). In addition, for nonathletic youth, sports drinks add a considerable number of unnecessary calories.

The Preparticipation Physical Examination for Sports

For many youth, the preparticipation physical examination (PPE) is their only health assessment for several years. It may serve as an entry into health care and enable the provider to schedule a follow-up visit to address other health risks and concerns. However, because PPEs are not required for many of the recreational activities in which youth engage, there is a recommendation by a consensus group (consisting of sports medicine practitioners and consultants from the American Academy of Family Physicians [AAFP], the AAP, the American College of Sports Medicine [ACSM], the American Medical Society for Sports Medicine, and the American Osteopathic Academy of Sports Medicine) that a PPE serve as an additional opportunity for a well-child examination for all children. In this way, health and fitness will be promoted and assessed in all children (Editorial Staff, 2010). Included in this examination should be the use of a health questionnaire that targets certain cardiac health issues and the use of standard PPE forms. The PPE monograph contains the recommended questionnaire, PPE, and clearance forms; they are available for downloading from the AAFP. The complete monograph also contains guidelines for clinicians evaluating children with special needs and the female athlete; it is available for purchase (AAFP, AAP, ACSM et al, 2010).

The PPE historically served as a vehicle to provide liability protection, satisfy insurance regulations, and detect cardiovascular risks for sudden death. Over the years, other objectives have been identified that include the following (DeBerardino and Owens, 2009):

The American Heart Association (AHA) recommends an initial comprehensive examination and then another PPE every 2 years for high school students with an interim history review in intervening years. The National Collegiate Athletic Association stipulates an initial comprehensive examination on entry into college level athletics, with interim questionnaires done in subsequent years. The AHA recommends both history and examination prior to entry into playing college sports and an interim history and blood pressure in the subsequent 3 to 4 years of college (DeBerardino and Owens, 2009).

Following a comprehensive PPE, an annual “screening” PPE may be requested, such as for high school students. Salient areas to cover include review of the complete health history with special addition to any interval history of syncope, chest pain, hypertensive symptoms, seizures, palpitations, injuries (orthopedic, neurological [concussions], eye), pulmonary and skin conditions, menstrual irregularities, and risky behaviors (including drug use). The physical examination itself should particularly assess cardiac (including checking femoral pulses), neurological, abdominal (palpating spleen, liver, kidneys), and musculoskeletal systems; as well as height, weight, and blood pressure (Chelminski, 2010).

Studies indicate that between 0.3% and 1.3% of athletes are disqualified from participation based on the findings of the PPE. Between 3.2% and 13.9% require further evaluation in order to be cleared (Greydanus and Patel, 2009). The majority of findings that disqualify a potential athlete or that give cause for further evaluation are musculoskeletal, followed by cardiovascular and then neurological complaints (Hergenroeder, 2008). Any positive cardiac findings on the history (personal or family) or on the physical examination warrants a referral for more in-depth cardiac evaluation prior to sports clearance (AAFP, 2010).

Table 13-5 provides recommendations and guidance on safe sports for various medical conditions and can be a useful reference for complex decision-making. In addition, consultation with the appropriate specialist working with the patient’s particular health condition may be needed before giving athletic clearance or recommending any specific modification or adaptation to a fitness regimen.
