Effects of Lower Limb Concentric Versus Eccentric Dynamic Resistance Training on Agility and Speed in Badminton Players

Effects of Lower Limb Concentric Versus Eccentric Dynamic Resistance Training on Agility and Speed in Badminton Players

With an average heart rate (HR) of more than 90% of the player's maximal HR, football is extremely taxing. The sporadic movements that occur throughout a game place a strain on the anaerobic and aerobic systems, accounting for roughly 30% of the latter's workload and 60% of the former. The capacity to shift directions and accelerate or decelerate on the court in order to make accurate shots and perform better is what determines footwork performance. Plyometric Training is a favored training technique for raising COD performance since it has a reputation for being a simple, quick, and efficient method of training. The core practice of combining resistance conditioning exercises with a dynamic warm-up can improve power output in badminton and create a post-activation performance enhancement (PAPE) impact. According to random sampling and sample size calculated by open epi tool, a total of 68 badminton players will be obtained from the badminton club of a Crescent sports club and Al-Fatah Sports Complex, Faisalabad. They will be divided into group A and group B according to the form of random sampling. Baseline markers for agility and speed will be taken before the start of the training and after the completion of training program. Group A will be engaged in a specially designed 30-minute concentric lower limb training program (squats, lunges and leg extensions) conducted by the researchers, before a 90-minute ordinary badminton training session conducted by the coach, 2 days per week for 8 weeks. Group B will be engaged in a specially designed 30-minute eccentric lower limb training program (wall sit, sitting straddle single leg and full squat) conducted by the researchers, before a 90-minute ordinary badminton training session conducted by the same coach, 2 days per week for 8 weeks.

The aim of the study is to find out the effects of concentric and eccentric dynamic resistance training on agility and speed in badminton players
