Brief Summary
|
This study aims to compare the effect of sprint interval training vs resistance type high intensity interval training on heart rate variability, cardiorespiratory fitness, performance, anaerobic capacity and some physiological measures in volleyball athletes. . A total of 40 volleyball athletes will be randomly allocated in the groups - SIT, R-HIIT and control group. The SIT group will perform the repeated bouts of short duration maximal intensity sprint exercise, while the R-HIIT will undergo a high intensity resistance based interval training and control group will perform their regular exercise. Both intervention groups will train three times per week for a period of 4 week in addition to their regular volleyball training. Outcome measures include HRV Aerobic capacity Jump performance Anaerobic capacity Physiological parameters such as BP, saturation, HRR, RR Will be assessed at the baseline and after completion of 4 week intervention. This study is designed as randomized controlled intervention trail with a parallel group design. |
