Comparison of Combined Sprint-Plyometric Training Versus Traditional Strength Training on Speed, Agility, Power, and Movement Quality in Intermediate Rugby Players: A Randomized Controlled Trial

What this Trial Is About

Researchers are evaluating the effects of combined sprint-plyometric training versus traditional strength training on speed, agility, power, and movement quality in intermediate-level rugby players aged 18 to 25 years. This randomized controlled trial aims to compare these two training methods over an 8-week period to understand their impact on athletic performance and neuromuscular training. Participants are randomly assigned to one of two groups. Group A completes progressive sprint (10-100 m) and plyometric exercises such as squat jumps, box jumps, single-leg hops, and depth jumps, with two sessions per week lasting 45 to 60 minutes each. Group B performs lower-body resistance exercises including barbell squats, leg presses, lunges, Romanian deadlifts, leg curls, and leg extensions at 60-80% of their one-repetition maximum, also twice weekly for 45 to 60 minutes. Both groups follow a structured progression over four two-week blocks with designated rest periods between sets and sessions. During the study, participants undergo assessments at the start and after the 8-week intervention. Measurements include sprint speed using electronic timing gates over 40 and 80 meters, agility via the T-Test, lower-body explosive power through the Standing Long Jump Test, and movement quality assessed by the Functional Movement Screen. These evaluations help researchers monitor improvements and differences between the training methods. The total participation spans the 8-week training and assessment period under medical supervision.
