Clinical Trial 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.


Description:

To compare the effect of plyometrics training and eccentric muscle training to improve functional performance in weightlifters. The study will be Randomized control trial. Non-Probablity propulsive techninque DATA COLLECTION TOOLS Lower Extremity Functional Scale Upper extremity Functional scale Vertical jump & long jump Seated medicine Ball toss V-sit and reach test The Data will be analyzed using SPSS for windows software version 25. Statistical significance P=0.05. After assessing the normality of current data by shapiro wilk test. it will be decided whether parametric or non parametric test will be used within the groups or between 2 groups.

Outcome

Type Measure Description Time frame Safety issue
Primary Lower extremity functional scale A reliable patient-rated outcome measure (PROM) for assessing lower extremity function is the lower extremity functional scale (LEFS). For a variety of lower-extremity diseases, the Lower Extremity Functional Scale (LEFS) is used to assess "patients' initial function, ongoing improvement, and outcome 6 weeks
Primary Upper extremity Functional scale A patient-reported outcome measure called the upper Extremity Functional scale is used to evaluate functional impairment in people with musculoskeletal upper limb dysfunction. 6 weeks
Primary Vertical jump & long jump Subjects were instructed to jump as high as possible and touch the highest point. The vertical jump was calculated by subtracting a subject's standing reach height from his maximal jump height.
The standing long jump is measure on a mat which was fixed to the floor. Subjects were permitted to perform a countermovement prior to jumping vertically or horizontally Subjects were instructed to jump as high as possible and touch the highest point. The vertical jump was calculated by subtracting a subject's standing reach height from his maximal jump height.
The standing long jump is measure on a mat which was fixed to the floor. Subjects were permitted to perform a countermovement prior to jumping vertically or horizontally
6 weeks
Primary Seated medicine Ball toss The seated medicine ball toss is to perform with a 3.6 kg medicine ball. The participants sat on the floor with their back against a wall and were instructed to toss the ball as far as they could with both hands at an approximate angle of 45° (similar to a chest pass). Prior to each toss the ball with weightlifting chalk so that when the ball landed on the floor it left a distinctive mark that allowed for a precise measurement. The distance from the wall to the near edge of the mark on the floor made by the ball was measured 6 weeks
Primary V-sit and reach test V-sit and reach test is use to measure flexibility of back muscles or hamstring muscles in a temperature control environment.1) Mark a baseline on the floor. 2) A ruler is placed perpendicularly to the baseline which cross the baseline at 15inches. 3) Sit with the heels on the baseline with feet 12inches apart. 4) With the legs straight, slowly bends forward to reach the furthest point of the ruler. 5) Hold for 2 seconds and record the distance. 6) Perform three trials with the best score recorded. 6 weeks
