Lower extremity joint flexibility and isokinetic performance differences in step aerobic exercise which was done with different music speeds

The aim of this study is to examine the effects of 12 weeks of step aerobic exercise program which is done with different music speeds on knee flexor and extansor muscle groups’ strength developments. That’s why two different music speeds (125 bpm and 130 bpm) were selected. The volunteer university students (40 women) were randomly assigned to two training groups. The first (age: 22,15 ± 2,52) and the second group (age: 22,05 ± 1,73) were trained with 125 bpm music speed and 130 bpm music speed, respectively, for one hour a day and three days a week. Before and after the training, the knee flexion/extension muscle strengths were measured 60, 180 and 300 deg/sec angular velocity with biodex system-3 dynamometer. After that training program, both of the groups’ muscle strengths values were increased (p<0,05). Between the two groups, statistically significant differences, as 300 deg/sec angular velocity, were found during the measurements (p<0,05). It was seen that the participants, who were trained with 130 bpm music speeds, reached well values for endurance measurements. As a result, it is stated that the step aerobic exercise, which was done with 130 bpm music speeds, is an effective method for developing the knee flexor and extansor muscle’s endurance.
