Effects of Contrast Strength Training in Badminton Players

Badminton is one of the most popular sports worldwide. In general, badminton jumping actions have two goals: achieve maximum height and reach a precise location using certain body movements. Both objectives are important in badminton and must be considered when conducting practical training sessions and imparting techniques. The players should have agility to move on the court forward sideward and backward to do many actions with high speed. They require sports specific training to achieve power, stability and agility in the ground for a powerful performance. Contrast strength training is multi-intervention programs and it has a certain influence on agility, power and speed. A sample size of 48 badminton players from Pakistan Sports Board, university level and badminton club players will be taken through Non-Probability Convenience Sampling technique. Sample size of players with age group between 17-28 years will be taken. Players will be selected on the basis of inclusion and exclusion criteria and will be equally divided into two groups by random number generator table. Group A experimental group will perform contrast strength training. Group B participants of the control group will follow their standard badminton practice over the same duration with no strength training design. Before and after completion of the respective training agility and power will be assessed through t-test and vertical jump test. For explosive speed 40-yard dash will be performed. Data will be analyzed by using Statistical Package for the Social Sciences (SPSS) for Windows Version 25.

Treatment and study plan

contrast strength training

Other

For eight weeks players performed Contrast strength training included bench press, pull-over, half squat, and forward lunge. Each session began with a 10-minute warm-up (jogging, dynamic stretching, and basic weightlifting exercises) and ended with a 5-minute cool-down. Training was performed twice a week for 8 weeks on non-consecutive days (Tuesday and Thursday). Exercises were done using free weights at 40-80% of 1-repetition maximum, in 3-4 sets of 2-4 repetitions

Primary outcomes

  1. Agility T Test

    Time frame: 8 weeks

    The T-test, an accurate approach with a good intra-trial reliability score was used to measure agility. The participants were told to touch the first cone with their right hand after running 9.14 meters from the starting line. They shuffled to the second cone, which was 4.57 meters to the left, then to the third, which was 9.14 meters to the right, touching it with their right hand, then reversing to the starting line after shuffling 4.57 meters to the center cone and touching it with their left

  2. Vertical Jump Power Test

    Time frame: 8 weeks

    The participant applies chalk to the tips of their fingers. After standing away from the wall, the individual uses both arms and legs to help project their body upwards and jumped as high as they are capable of. Attempt to touch the wall at the top of the jump. Power will be measured by Sargent Test.

  3. 40-Yd Speed Test

    Time frame: 8 weeks

    Speed was evaluated using the 40-Yard Sprint Test, which involves completing a single maximum-effort sprint over a 40-yard distance while recording the time. The purpose of this test was to assess the participants' 40-yard sprint performance.
