Abstract	Background: Goalball is a Paralympic sport specifically designed for individuals with visual impairment and requires considerable physiological fitness and cardiovascular efficiency for successful performance. Plyometric training has been widely recognized as an effective training method for improving athletic and physiological performance. However, limited research has been conducted among visually impaired Goalball players. Purpose: The purpose of the study was to examine the effect of plyometric training on selected physiological variables among visually impaired male Goalball players. Methodology: A total of sixteen visually impaired male Goalball players were selected as subjects and randomly divided into two groups namely the experimental group (n=8) and the control group (n=8). The experimental group underwent a systematic plyometric training programme for a specified duration, while the control group continued their regular routine activities. The selected physiological variables were VO₂ Max and Resting Heart Rate. Pre-test and post-test measurements were collected using standardized testing procedures. The collected data were analyzed using Analysis of Covariance (ANCOVA). Results: The results of the study revealed significant improvements in VO₂ Max and Resting Heart Rate among the subjects in the experimental group compared to the control group. The findings indicate that plyometric training positively enhanced aerobic capacity, cardiovascular efficiency, and physiological fitness among visually impaired Goalball players. Conclusion: The study concluded that plyometric training is an effective training method for improving selected physiological variables among visually impaired Goalball players. The findings emphasize the importance of incorporating plyometric exercises into adapted sports training programmes to improve physiological performance and athletic efficiency among visually impaired athletes.
