Abstract des Autors

The purpose of the present study was to determine whether improvements in quadriceps (Q) and hamstrings (H) muscular strength (MS), power (MP), and endurance (ME) could be attained from bench step aerobics (BSA). Twenty-four healthy adults ranging from 24 to 61 yrs of age completed the study. The exercise group (E) consisted of 13 novice steppers who participated in a 10-week BSA class three times a week for 50 min at 65-80% max heart rate. A control group (C) of 11 individuals maintained their usual activity level. MS (peak torque at 60ø/sec), MP (best work rep at 180ø/sec), and ME (total work achieved from 20 rps at 300ø/sec) were determined on Q and H using a Cybex 340 isokinetic dynamometer. MS of the Q in both groups showed a significant decrease from pre- to posttest measures. There were no significant changes in MS of the H for either group. No significant change was observed in MP for Q and H in either group. Endurance increased for Q and H in the exercise group, but not significantly. No significant change in ME was observed in the control group. Percent body fat decreased significantly in the exercise group but not in the controls. BSA does not appear to provide the necessary stimulus for improvements in muscle strength, power, or endurance as measured by computerized isokinetic dynamometry. Verf.-Referat
