EXERCISE ADHERENCE Damon Burton University of Idaho

WHAT IS EXERCISE ADHERENCE? Exercise Adherence (EA) – is the ability to maintain an exercise program for an extended time period. Exercise adherence is one of the biggest health problems for American adults. EA is also a problem for children and adolescents, probably due in part to extensive reductions in required physical education classes.

EXERCISE STATISTICS 30% of adults are sedentary (i.e., totally inactive). Physical activity levels begin to decline at age 6 and continue throughout the life cycle % of adults get health benefits from physical activity. 64% of Americans were considered overweight or obese in % of American adults were considered overweight in 2000 compared to 45% in 1991.

EXERCISE STATISTICS Among youth ages 12 to 21, 50% do not participate regularly in physical activity. Among adults, only 10-15% exercise 3 times per week for at least 20 minutes. Among boys and girls, physical activity declines steadily thru adolescence from 70% at age 12 to 40% at age 21. Women are more active than men, blacks and Hispanics more than whites, older adults compared to younger ones, and less affluent compared to more affluent.

EXERCISE STATISTICS 10% of sedentary adults begin exercise programs each year, 50% of new exercisers will drop out within six months.

EXERCISE BEHAVIOR THEORIES & MODELS Health Belief Model, Health Belief Model, Theory of Planned Behavior, Theory of Planned Behavior, Self-Determination Theory, Self-Determination Theory, Transtheoretical Model, and Transtheoretical Model, and Ecological Model. Ecological Model.

HEALTH BELIEFS MODEL Becker & Maiman (1975) suggest that the likelihood of an individual’s engaging in preventive health behaviors such as exercise depends  on the person’s perception of the severity of potential illness and  their appraisal of the costs versus benefits of taking action.  For example, a person who believes the potential illness is serious, he/she is at risk and the pros of taking action outweigh the cons is likely to exercise regularly.

THEORY OF PLANNED BEHAVIOR Ajzen & Madden (1986) extended Theory of Reasoned Action that identified intentions as the best predictors of actual behavior. Intentions are the product of an individual’s attitude toward a particular behavior and subjective norms regarding that behavior. Subjective norms are a product of beliefs about others’ opinions and motivation to comply with others’ opinions.

THEORY OF PLANNED BEHAVIOR For example, the Theory of Reasoned Action (TRA) suggests that if you are a nonexerciser and believe that other significant people in your life (e.g., wife, children, & friends) think you should exercise, you may wish to do what other want you to do. Theory of Planned Behavior (TPB) extends TRA by arguing that intentions cannot be the sole predictors of behavior, particularly when individuals lack control over behaviors.

THEORY OF PLANNED BEHAVIOR In addition to subjective norms and attitudes, TPB states that perceived behavioral control (i.e., people’s perception of their ability to perform the behavior) also affect behavioral outcomes. TPB has been the most frequent theory to be used to predict exercise behavior, although it typically accounts for only 20-35% of the variance in exercise behavior.

TRANSTHEORETICAL MODEL Stage 1 = Precontemplation: Person isn’t performing self- change behavior and doesn’t intend to start. Initial notice of a problem. Stage 2 = Contemplation: Person isn’t performing the self-change behavior but are thinking about starting. Action seriously considered.

TRANSTHEORETICAL MODEL Stage 3 = Preparation: Person recently started preparing to initiate self-change behavior such as buying clothing and shoes, purchasing a fitness membership or lining up an exercise partner. Stage 4 = Action: Person has initiated the self-change behavior consistently for a short period of time. Trying to become more systematic.

TRANSTHEORETICAL MODEL Stage 5 = Maintenance: Person has maintained the self-change behavior consistently for 6 months or more and plans to continue doing so. Reached habitual stage. Stage 6 = Relapse Prevention: Person encounters serious lifestyle change after reaching maintenance stage and has to adjust self change program to prevent relapse. Making needed adjustments to maintain lifestyle change.

REINFORCEMENT APPROACHES charting attendance and participation, rewarding attendance and participation, and feedback and testing.

COGNITIVE-BEHAVIORAL APPROACHES goals, self talk, and thought focus strategies association association dissociation dissociation

DECISION-MAKING APPROACHES

SOCIAL SUPPORT APPROACHES social support from partner, group or class, know where to go for what you need, and must trust and respect person to go to them for support.

INTRINSIC APPROACHES focus on the experience, focus on the process and engage in meaningful physical activity.

BEST EXERCISE ADHERENCE STRATEGIES 1.Make exercise fun and enjoyable. 2.Tailor exercise frequency, duration and intensity to the exerciser. 3.Promote group exercise. 4.Keep daily exercise logs. 5.Reinforce success. 6.Find a convenient place to exercise.
