Summary

In the field of football, the essence of the lower limb strength, power and general performance is greatly valued by any player who wants to perform exceptionally well in both the acceleration, jumping and general agility. Conventional strengthening techniques have always been basic and recent strategies such as the Accentuated Eccentric Loading (AEL) and Flywheel (FW) have been considered as the inventions. AEL increases the muscle contraction during the eccentric phase of exercises and therefore improves hypertrophy and strength. On the other hand, FW uses leverage kinetic energy to oppose, thus, promotes muscle contractions and changes constantly. There is different training modalities that can be applied during training sessions or in prepare to a particular event such as football. Thus, it is essential to compare the applicability of those modalities in training football players. This study design will be Randomized clinical trial. Thirty-six male age 18-21 years who consistently play football and participate in resistance training from previous one year will randomly assigned to the two different exercise protocol i.e. Accentuated eccentric loading and Flywheel. The participants will undergo training program for total of 8 weeks. These two groups will exercise three days in a week and each session will take about 60-75 minutes. In this study researcher will use Back Squat and Leg Press for lower limb strength. Hip thrusts and Broad Jump for lower limb power. Free weights or Weight Machines, 20- meter sprint test and Agility T-test to measure performance of footballers. Data will be analyzed using SPSS version 25.

Detailed description

The objective of this study is to compare the impact of Accentuated Eccentric Loading and Flywheel exercises on lower limb strength, power and performance in Football Players.

• Sports Physical Therapy

Interventions

Type	Name	Description
OTHER	Accentuated Eccentric Loading training	18 particpants will train in AEL group for three days a week for eight weeks and each session will take about 60-75 minutes, focusing on eccentric exercises like back squats, leg press, and hip thrusts at 90% 1RM intensity. Sessions, supervised by coaches, include free weight and weight machine exercises. Performance tests (20m sprint, T-agility, broad jump, 1RM assessments) will evaluate progress at the study's start and end.
OTHER	Flywheel exercises	18 particpants will train in FW group for three days a week for eight weeks and each session will take about 60-75 minutes, incorporating compound movements, Flywheel exercises (squats, sprints, jumps), and relevant free weight and weight machine exercises. Supervised sessions maintain consistent parameters. Performance tests (20m speed, T-agility, broad jump, 1RM assessments) will measure improvements at study start and end for evaluation.
