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

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

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

This randomized controlled trial compares combined sprint-plyometric training (Group A) versus traditional strength training (Group B) in 64 intermediate-level rugby players (aged 18-25 years). Both interventions are delivered over 8 weeks at 2 sessions per week. Primary and secondary outcomes include speed (40 m and 80 m sprint via electronic timing gates), agility (T-Test), lower-body explosive power (Standing Long Jump), and movement quality (Functional Movement Screen), assessed at baseline and post-intervention. Randomization is performed via computer-generated sequence.

Inclusion Criteria:

1. Male and female athletes aged 18-25 years
2. A minimum of 2 years of structured rugby training experience
3. Actively training at least 3 hours per week
4. Medically cleared to engage in high-intensity physical activity
5. Willingness to participate and provide written informed consent

Exclusion Criteria:

1. History of moderate or severe musculoskeletal injuries or surgery within the past 6-12 months
2. Not medically approved to engage in high-intensity physical activities
3. Cardiovascular or cardiopulmonary disease or risk factors that contraindicate high-intensity training
4. Participation in any additional structured strength or plyometric program outside the study protocol during the intervention period
