Effects of Plyometric Training and Eccentric Muscle Training on Functional Performance in Weightlifters

Summary

Stretching, pressing, and lifting large weights with speed and balance all require strong muscles. In plyometric exercise, the same muscle must be stretched and rapidly contracted in order to make quick, strong motions. Plyometric exercises include explosive jumps, hops, bounds, and skips. A major component in becoming a better weight lifter is plyometric training that focuses on the lower limb. Additionally, as the muscle produces and stores kinetic energy, it is crucial to increase muscle power, strength, and endurance. Eccentric muscular activity relate to the dynamic extension of muscle tissue in resistance to an external force or load. Eccentric muscular activities have been demonstrated to induce a higher elevation of molecular signalling pathways connected to muscle and connective tissue anabolism and increased activation of satellite cells.

This study will be a Randomized control trial and occur on improving functional performance in weightlifters. The inclusion criteria are, training will perform only elite weightlifters, aged between 20-30 years, and have 4-5 years of weightlifting experience. In this study we will compare two groups including 20 participants, 10 participants will be trained in plyometric exercises and 10 participants will be on eccentric muscle training and we will analyze which group will enhance functional performance. We will use an Assessment scale to assess the upper and lower extremity dysfunction through the Upper extremity assessment scale and Lower extremity assessment scale.
