Effects of the Youth Fit For Life Protocol on Physiological Factors, Mood, Self-Appraisal, Voluntary Physical Activity, and Fruit and Vegetable Consumption in Children Enrolled in YMCA After-School Care Annesi, James J.: YMCA of Metropolitan Atlanta; Faigenbaum, Avery D.: The College of New Jersey Dept of Health and Exercise Science; Westcott, Wayne L.: South Shore YMCA; Smith, Alice E.: Children’s Healthcare of Atlanta; Dixon, Gayle M: YMCA of Rock River Valley. Changes associated with the Youth Fit For Life physical activity intervention were assessed with 5- to 12-year-old children in after-school care (N = 477). Body mass index (BMI), strength, and flexibility significantly improved over 12 weeks. Initial BMI was negatively related to observed changes, r = -.29, p < .001. Significant within-group improvements in Tension, Vigor, and Physical Self-Concept scores, and levels of voluntary moderate-to-vigorous physical activity/week were also found in the 9- to 12-year-olds (n = 91). Multiple regression analysis indicated that changes in Physical Self-Concept, Exercise Self-Efficacy, and General Self scores explained a portion of the variance in changes in voluntary physical activity that approached significance, R2 = .08, F = 2.55, p = .06. Revisions and extensions of the protocol were suggested.
