Abstract

Background and Study Aim. Dehydration is a condition where there is a lack of fluid in the body, accompanied by disturbances in the body's metabolic processes. This study aims to prove the effect of dehydration on 5 lap running by comparing the pulse rate before and after dehydration.Materials and Methods. This study used an experimental method. The population in this research is Tanjungpura University sports students. Purposive sampling technique so that a sample of 19 students was obtained. The sample consists of 4 women and 15 men. In the research, the implementation procedure will be to measure 2000 meter running performance before and after losing fluid, weighing body weight to precision ounces. Analysis was assisted using SPSS 26.Results. The results of the analysis showed a significance value of 0.000 <0.05, which is a significant difference between the pulse rate before and after dehydration when running 5 laps. The pulse rate after dehydration tended to be higher, indicating an increased cardiac workload during physical activity.Conclusions. This study concludes that dehydration has a direct influence on pulse rate when running 5 laps. The existence of this difference highlights the importance of maintaining an optimal hydration state in supporting a healthy cardiovascular response during physical activity, particularly in high-intensity exercise such as running. These findings can be used as a basis for the development of more effective hydration strategies in the context of aerobic physical activity.

Abstract

Background Handball is an intermittent, high-intensity sport that demands sustained aerobic capacity to maintain optimal performance during training and competition. Adequate VO2max levels are therefore essential for athletes to cope with repeated bouts of explosive movement and prolonged physical exertion. Objectives This study aimed to examine the effectiveness of a circuit training method in improving physical condition, specifically VO2max levels, among handball athletes. Methods An experimental one-group pretest–posttest design was employed. The participants consisted of 15 athletes from the Sambas district handball team, aged 20–25 years, selected through purposive sampling. The athletes completed a structured circuit training program implemented across 12 sessions with a frequency of three sessions per week. VO2max was assessed before and after the intervention using the Yo-Yo Intermittent Recovery Test Level 1. Data were analyzed using SPSS 26. Results The findings revealed a significant improvement in VO2max following the circuit training program, with a significance value of 0.000 (< 0.05). These results indicate that circuit training is effective in enhancing aerobic capacity among handball athletes Conclusion Circuit training provides a substantial positive impact on VO2max development in handball players, supporting its use as a conditioning strategy to improve overall physical performance. This study contributes empirical evidence on the effectiveness of circuit-based conditioning for intermittent sports. The results offer practical insights for coaches and sport practitioners in designing targeted training programs aligned with the physiological demands of handball athletes.
