About this study
Official title: Effects of Accentuated Eccentric Loading Versus Flywheel Exercises on Lower Limb Strength, Power and Performance in Footballers
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Accentuated Eccentric Loading trainingOther
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.
Flywheel exercisesOther
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Back Squat
Back squats compose muscular strength of lower limbs and hence, they were performed at a load of 90% of 1 RM. They recruit the quadriceps, hamstrings, gluteal muscles and the lower back skeletal muscles. It can be concluded that back squat as a measure of maximal strength is reliable and valid especially in athletic subjects such as football players. Cronbach alpha is significant in strength assessment in sports using back squats; test-retest reliability ICC equals 0. 97 and construct validity has been discovered in existing works.
Measured: 8 weeks
Hip Thrusts
At 90% 1RM hip thrust with the barbell aims at the gluteal muscles and plays an essential role in the improvement of hip extension power needed profoundly in sprinting and jumping in football. This exercise has been proven to help in enhancing hip strength as well as sprint performance; meanwhile, the reliability coefficient of the test in measuring maximal strength in athletes was very high (ICC = 0. 94). The hip thrust's focus on the posterior chain renders it a measure of lower limb strength that is directly applicable to football performance.
Measured: 8 weeks
Broad Jump
The broad jump is a test that is frequently used in lower body power, which tracks the force thatan individual athlete is able to produce quickly. This exercise is quite pertinent for football players since it replicates the kind of movements involved in football. The broad jump has shown test-retest reliability of Internal Consistency Coefficient, ICC= 0. 95 and construct validity in determining lower body power of athletes. It is easy to administer, sensitive and reliable and thus widely accepted as a standard measure in athletic ability assessment.
Measured: 8 weeks
Leg Press Machine
The leg-press equipment is used perform unilateral leg-press exercise to determine 1-RM strength and the maximal voluntary isometric contraction (MVIC). This exercise focuses on the quadriceps, hamstrings, and glutes by comparatively giving a controlled situation to determine lower limb force. In correlating maximal strength in the context of the leg press, previous studies have found very high to almost perfect reliability (ICC = 0. 96) as well as validity in populations that demand accurate determination of unilateral leg strength.
Measured: 8 weeks
Agility T-test
Agility T-test checks how quickly players can change direction and control their body. Players start by sprinting forward, go around a cone, weave through middle cones to the top, turn, weave back through, circle another cone, and sprint to the finish. This tool reliability showed a highICC in almost all studies.
Measured: 8 weeks
20 Meter Sprint test
The 20m sprint test assesses speed over a greater distance compared to the 10m sprint test. Studies have demonstrated that the 20m Sprint Test maintains validity and reliability when performed using electronic timing gates.
Measured: 8 weeks
