Recovery from delayed-onset muscle soreness: traditional technique versus whole-body vibration

None listed

This project will investigate the effects of two different exercise modalities to recover from delayed-onset muscle soreness (DOMs) generated by eccentric exercise of the leg musculature. The two recovery modalities are a traditional recovery technique (static stretching) and whole body vibration exercise (WBV) where a person stands on a vibration plate. The traditional technique is commonly used to recover from DOMS but is not associated with increased blood flow in the legs. Increased blood flow in the legs, however, is thought to be a significant factor in the recovery from DOMS. WBV has been shown to significantly increase blood flow in the legs, therefore, it is hypothesised that it will reduce the intensity of DOMS generated by eccentric exercise of the leg musculature (backward slow walking on a treadmill). The level of DOMs will be assessed by a measurement of shank swelling (lower leg) and a muscle soreness rating. It is known that DOMs reduces strength and power output, and joint range of motion (ROM) in the hip, knee and ankle. These parameters will be measured by a vertical jump for maximum height, muscle activation through electromyography and joint ROM (ankle, knee and hip) with a goniometer. DOMs recovery will also be assessed by recording walking and running patterns since these are significantly affected by DOMS.
