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

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

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