108 high school girls were assessed to determine if exercise alone or in combination with relaxation training affected their physical fitness. Resting heart rate, recovery heart rate, systolic and diastolic blood-pressure readings were pretest and posttest measures. Statistically significant interactions occurred for recovery heart-rate scores but changes could not solely be attributed to treatment. Although resting and recovery heart-rate scores were reduced following treatment in both groups, results were nonsignificant. It was recommended that physical education units be longer than 4 wk. in length when significant fitness improvements are desired.

AbstractObjectivesSome factors in infancy can play a role in the development of adolescent obesity. Understanding these factors can help prevent early complications in adolescents associated with obesity in adulthood. The aim of this study was to determine the prevalence of overweight and obesity among high school girls in Khorramabad and its relationship with breastfeeding history.MethodsThis was a cross-sectional study. This study was conducted in 832 high school girls during the academic year 2016–2017. Samples were selected by multi-stage random sampling. General questionnaires, physical activity, and 24-h food questions were completed through interviews with students. Data regarding breastfeeding was obtained by mothers.ResultsThe prevalence of overweight and obesity in the study population was 16.3 and 5.8%, respectively. Overweight and obesity had a significant association with breastfeeding history (p = 0.001), while there was no significant relationship between overweight and obesity with school type, student’s age, parental occupation, education Parents, household size, birth rate, physical activity, and energy intake.ConclusionsThe results of this study showed that breast feeding has a protective effect on overweight and obesity during adolescence.
