Objectives Whole body vibration (WBV) training appears to be an effective alternative to improving physical function in the elderly.The purpose of this study was to etermine comparison of the effect of eight weeks of combined vibration - rope skipping with two different intensities on physical performance in elderly men.
Methods & Materials Thirty elderly men (mean age 65.83±4.16 years; height 169.26±3.90 cm; weight 77.04±4.62 kg; body mass index 26.86±0.69 kg per square meter) living in Mashhad, Iran in 2019, who were selected using a convenience sampling method.They were randomly selected and randomly divided into three groups: high intensity (n=10), low intensity (n=10), and control (n=10). Vibration training were performed intensity with frequency 25-40 HZ and amplitude 3 mm. Rope skipping training was applied for both groups based on Borg scale at 13-14 level intensities with 30-35 jumps per minute for both groups. Physical performance indices, body mass index, and fat percentage were measured at pre-test and at the end of eight weeks. Analysis of variance with repeated measurements were used for data analysis. Significance level (P≤0.05) was considered and SPSS software version 20 was used.
Results Indicators lower body flexibility­ (105%), ­­upper limb muscle strength ­(42.43%), handgrip strength (43.38%), dynamic leg strength (36.47%), lower extremity muscle endurance performance (27.2%), cardio-respiratory function (10.27%), balance function (-32.6%), and body fat percentage (-4.5%) There was a significant improvement in training groups (p<0.05). The results showed in the exercise groups, all the performance indicators except body mass index improved (p<0.05). But there was no significant difference between the two training groups in any of the variables(p>0.05).
Conclusion It seems that low intensities of the vibration - rope skipping combination program can be effective in improving body composition and physical function in elderly people. The choice of each program depends on the fitness of the elderly.
