Integrative approach of plyometrics and nutritional strategies on vertical jump performance in elite targetball players

Purpose: This study aimed to evaluate the impact of combining plyometric training with a structured nutritional plan on the vertical jump height of elite Targetball players. It also examined the correlation between improvements in jump height and various factors, including the provided nutritional support, to determine whether this combined approach leads to superior outcomes compared to plyometric training alone. Material and Methods: Thirty-six elite male Targetball players from Tamil Nadu, India, aged 20 to 25 years, were randomly assigned into three groups: Plyometric Training Only (PTO), Plyometric Training with Nutritional Support (PTNS), and a control group (CG). Over a 12-week period, the PTO group engaged solely in plyometric exercises, while the PTNS group received the same plyometric regimen plus a structured nutritional plan focusing on protein intake and hydration. The control group received no specific training or nutritional intervention. Vertical jump height was assessed using the countermovement jump (CMJ) test. Data were analyzed using ANOVA to compare jump heights across groups before and after the intervention and Pearson correlation analysis to examine relationships between jump height improvements and nutritional support, with significance set at p < 0.05. Results: The ANOVA revealed no significant differences in pre-test vertical jump heights among the groups (F = 0.56, p > 0.05). However, significant differences were observed post-test (F = 54.79, p < 0.05), with the PTNS group showing the greatest improvement in jump height compared to the PTO and CG groups. Correlation analysis indicated that height was strongly associated with jump height (r = 0.859, p < 0.05), while protein intake and water consumption had weaker correlations. Conclusions: Combining plyometric training with a structured nutritional plan significantly enhances vertical jump height compared to plyometric training alone or no intervention. The results underscore the benefits of integrating nutritional strategies, especially focusing on adequate protein intake and hydration, to optimize the effectiveness of plyometric training. The findings highlight the importance of a holistic approach to athletic training that includes both physical and nutritional elements to maximize performance and reduce injury risks
