Effect of fartlek and plyometric training on speed, speed endurance and explosive strength among male rugby players: A comparative study

Background: Rugby is a high-intensity collision sport demanding exceptional physical fitness characterized by speed, explosive power, and endurance. Fartlek training and plyometric training have emerged as prominent conditioning methodologies; however, comparative evidence regarding their relative effectiveness for developing physical parameters in rugby players remains limited. Objective: This study aimed to compare the effects of twelve-week fartlek training and plyometric training interventions on speed, speed endurance, and explosive strength among male rugby players. Methods: Ninety beginner male rugby players (aged 19-25 years) from Panjab University affiliated colleges were randomly allocated into three groups: Fartlek Training Group (n=30), Plyometric Training Group (n=30), and Control Group (n=30). The experimental groups underwent training three sessions per week for twelve weeks. Physical parameters were assessed using standardized tests: 50-meter dash for speed, 150-meter run for speed endurance, and vertical jump test for explosive strength. Data were analyzed using paired t-test for within-group comparisons and Analysis of Covariance (ANCOVA) for between-group comparisons at p
