UPHILL–DOWNHILL TRAINING AND 100-M SPRINT PERFORMANCE IN CLUB ATHLETES

Abstract

Objectives: This study examined changes in 100-m sprint performance after a combined uphill–downhill training program among athletes from the Kijang Rinjani Athletics Club. Materials and Methods: A one-group pretest–posttest design involved 10 active athletes selected purposively. Participants completed 12 sessions over four weeks, with three sessions per week. Sprint performance was assessed using a timed 100-m test before and after training. Paired observations were analyzed with a paired-samples test, and the magnitude of change was summarized using a confidence interval and standardized effect size. Results: Mean sprint time decreased after training. The reduction was statistically significant and represented a large within-participant standardized change. Conclusions: The program was associated with a small but meaningful improvement in 100-m sprint time. Because the study lacked a control group and included a small sample, controlled research is needed before the improvement can be attributed specifically to uphill–downhill training.
