The evaluation of the effectiveness of a protocol involving whole-body vibration in individuals with delayed-onset muscle soreness after eccentric exercise
This study is a single blind, single center, randomized clinical trial. Unaccustomed physical activity, specially eccentric exercise like downhill running, plyometric and strengthening exercises cause pain and irritation after exercise which are generally known as Delayed Onset Muscle Soreness (DOMS).
Volunteers which are university students will be randomly allocated in control and intervention groups (each group=26). At the beginning of the first session, height, weight and age will be asked. Students in both groups will walk on the treadmill for 5 minutes with the speed of 3 km/h to warm up. To introduce DOMS, participants will walk on the treadmill for 30 minutes at the speed of 4 km/h and slope will be increased to 10 gradually. Participants in intervention group will receive whole body vibration treatment and control group will walk on the treadmill for 5 more minutes with no grade at the speed of 3 km/h.
The outcome measurements are pain, dominant thigh circumference, passive knee ROM and maximum isometric knee extension power which will be measured at the beginning and end of each session and 1,3,7 days later.
