Abstract
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.
