This study examined the effects of three sprint-training modalities assisted, resisted, and combined sprint training on two key performance variables, speed and anaerobic power, in collegiate sprinters. Forty male athletes aged 18-23 years were randomly assigned to four groups: assisted sprint training (N=10), resisted sprint training (N=10), combined sprint training (N=10), and a control group (N=10). The experimental groups participated in a structured six-week training program consisting of three sessions per week, while the control group continued regular physical activity without sprint-specific training. Pre- and post-test measurements included 40-m sprint time to assess speed and the Wingate anaerobic test to evaluate anaerobic power. Data were analyzed using Analysis of Covariance (ANCOVA), followed by Scheffé’s post-hoc test. Results revealed that significant improvements in both speed and anaerobic power among all experimental groups compared to the control group (p<0.05). The assisted sprint training group demonstrated the greatest improvement in speed, suggesting enhanced neuromuscular coordination and stride frequency derived from supramaximal running. Conversely, the resisted sprint training group produced the highest increase in anaerobic power, likely due to increased horizontal force production and enhanced ATP-PCr energy system activation. The combined training group showed substantial improvements in both variables, though not exceeding the single-method superiority of the assisted or resisted groups. Overall, the findings indicate that all three sprint-training methods can be effectively selected based on specific performance goals. Assisted training is optimal for improving speed, resisted training for increasing anaerobic power, and combined training for balanced development.
