Brief Summary

The specific aims of this study are to: 1) evaluate the impact of a novel intervention delivered via school-based physical education (PE) on adolescents who have a high sensitivity to exercise-induced negative affect; 2) determine whether adolescents' tendency to feel uncomfortable during exercise is a stable trait that persists even in the face of an intervention; and 3) compare and contrast three alternative methods of measuring adolescents' sensitivity to exercise-induced affect. Healthy middle-school students who do not participate in team or individual competitive sports will be recruited and assessed to determine their existing predisposition toward exercise (i.e., "reluctant exercisers" and "latent exercisers"). The assessment will be conducted using three methods that have been used to measure individuals' propensity to experience positive affect in the face of a stimulus: 1) a pencil-and-paper assessment that measures tendency to respond to a challenge with positive affect; 2) electroencephalogram (EEG) to ascertain frontal cortical asymmetry; and 3) empirically assessed affective response to a standardized exercise task. Reluctant and latent exercisers will be assigned in equal numbers to one of two conditions. One condition will implement a PE-based intervention that differs from the traditional approach in that students will be instructed to exercise at an intensity that has been determined to elicit positive affect in that individual (based on baseline testing). In the other condition, students will be instructed to exercise at an intensity derived from standard formulas typically used in exercise prescriptions. It is hypothesized that the non-traditional approach will increase reluctant exercisers' enjoyment of PE and also their level of participation in physical activity outside of PE. The latter will be determined using portable monitors (accelerometers) worn at baseline, after the intervention, and again 1 year after the end of the intervention.

Outcome Measures

Primary Outcomes (1)

• Physical Activity

  Participation in physical activity is assessing objectively (using activity monitors), by self-report, and indirectly via cardiorespiratory fitness.

  1 year

Secondary Outcomes (1)

• affective response to exercise

  1 year

Study Arms (2)

Exercise prescription

EXPERIMENTAL

Participants are given an exercise prescription in the form of a target heart rate range for exercising. The range is determined based on their personal preferences so that it is an intensity that feels "good".

Behavioral: feeling states exercise intervention

traditional exercise

ACTIVE COMPARATOR

participants are given an exercise prescription based on percent of vo2 peak

Behavioral: feeling states exercise intervention

Interventions

feeling states exercise intervention BEHAVIORAL

exercise prescription based on intensity of exercise that feels good.

Exercise prescription; traditional exercise
