Effect of high-intensity interval training and interval training on the vital capacity of badminton players

Abstract:This study investigates the effects of High-Intensity Interval Training (HIIT) and traditional Interval Training (IT) on the vital capacity of collegiate badminton players aged 19 to 23 years in Guwahati. A total of 30 players were randomly selected and divided into two groups of 15 participants each. Prior to participation, informed consent was obtained from all subjects. The study utilized baseline spirometry to measure vital capacity as the primary criterion variable. The HIIT protocol involved repeated cycles of 20-second maximum intensity sprints at 85-95% max heart rate, interspersed with 10 seconds of rest over 15-20 minutes, while the IT sessions consisted of 1-minute moderate-intensity running followed by 30 seconds of low-intensity recovery at 65-75% max heart rate for 20-25 minutes.
Data collection entailed pre and post-testing of vital capacity, with results analyzed for statistical significance between groups. In the HIIT group, results demonstrated a highly significant improvement with a mean difference of 0.25 (p<0.001), indicating substantial enhancement in vital capacity. The 95% confidence interval for this difference ranged from 0.1555 to 0.3445. Similarly, the IT group also exhibited a statistically significant increase in vital capacity (mean difference 0.1333, p = 0.003), with a confidence interval of 0.0544 to 0.2122. These findings suggest that both HIIT and IT are effective training modalities for improving respiratory performance in collegiate athletes, with HIIT showing a larger effect size.
