Effects of Varied Intensities of Aerobic Training on Selected Physical Variables Among Volleyball Players

The study explores the efficacy of varied intensities of aerobic training on selected physical variables among volleyball players. Aerobic training is a cornerstone for enhancing athletic performance, endurance, and overall physical fitness, particularly in volleyball, where sustained agility and stamina are critical. This research aimed to investigate the impact of low, moderate, and high-intensity aerobic training protocols on physical attributes such as cardiovascular endurance, muscular strength, flexibility, and agility.

A total of 60 female volleyball players, aged 18–25 years from Andhra Pradesh, were randomly assigned into three experimental groups and one control group. The experimental groups underwent structured aerobic training sessions at different intensities—low (50–60% HRmax), moderate (60–70% HRmax), and high (70–85% HRmax)—for six weeks, while the control group followed their regular training routine.

Pre- and post-intervention assessments were conducted using validated tools and protocols. Cardiovascular endurance was measured using the Cooper 12-minute Run Test, muscular strength through the Handgrip Strength Test, flexibility using the Sit-and-Reach Test, and agility with the Illinois Agility Test. Statistical analysis was performed using paired t-tests to evaluate within-group differences and one-way ANOVA to compare between-group differences for the pre- and post-test scores of each physical variable. Post-hoc tests (Tukey’s HSD) were applied to determine the significance of pairwise group differences. A significance level of p < 0.05 was used to validate the results.

The results demonstrated significant improvements in cardiovascular endurance, agility, and flexibility in the moderate and high-intensity groups compared to the low-intensity and control groups. High-intensity training showed marginally greater benefits for agility and cardiovascular endurance, whereas moderate-intensity training was most effective for improving flexibility and muscular strength. The findings underline the importance of tailored aerobic training regimens to optimize performance in volleyball. This study contributes to the field of sports science by offering insights into intensity-specific training adaptations, aiding coaches and athletes in developing evidence-based training strategies.
