The present study aimed to investigate the differential effects of anaerobic, interval, and combined training packages on selected physiological efficiency variables among intercollegiate volleyball players. Thirty-six male volleyball players aged 18 to 25 years from Thoothukudi District, Tamil Nadu, India, were randomly assigned to three groups: Anaerobic Training Group (ATG), Interval Training Group (ITG), and Combined Training Group (CTG), each consisting of twelve participants (n = 12). The experimental period lasted 8 weeks, with three training sessions per week. Physiological variables such as Forced Vital Capacity (FVC), Maximum Voluntary Ventilation (MVV), and Tidal Volume (TV) were measured using a digital spirometer. Data were analyzed using paired sample ‘t’-tests, Analysis of Covariance (ANCOVA), and Scheffé’s post-hoc test at a 0.05 significance level. The results revealed significant improvements in all physiological parameters across the three training groups. Among them, the Combined Training Group (CTG) demonstrated superior gains in FVC, MVV, and TV compared to the Anaerobic and Interval Training Groups. The findings suggest that integrating anaerobic and interval training components produces more comprehensive adaptations by enhancing both aerobic endurance and anaerobic power systems. Therefore, combined training can be recommended as an effective approach for improving physiological efficiency and performance among volleyball players.
