Chimney Jump and Standing Leg Extension Training Increases the Lower Extremity Power of Volleyball Athletes

Abstract

Background. The Covid-19 pandemic has caused various adaptations in the world of sports. One form of adaptation that is carried out is training at home or known as training from home (TFH). Study purpose. This study aims to see the effectiveness of the chimney jump and standing leg extension exercises carried out by volleyball athletes during training at home or training from home (TFH). Materials and methods. A total of 36 volleyball athletes with an age range of 19–20 years were selected by purposive sampling and divided into the chimney jump (KCJ) group, the standing leg extension (KSE) group, and the control group (KKL). This research is quantitative research with a quasi-experimental research design with one group pretest posttest design. The three variables used as the dependent variable are agility, balance, and athlete’s leg power which were measured before TFH and after the athlete carried out TFH for 3 months. The results of the exercise were analyzed descriptively and continued to be analyzed using the Independent Samples T-test and One-Way ANOVA. Results. There was a significant difference in the results of the leg power posttest of the three groups (<.05) with KCJ having the highest average leg power (77.76 ± 9.38). Furthermore, KSE has the highest average in agility (56.83 ± 11.93) and balance (38.75 ± 3.02). Conclusions. Based on the results of this study, it can be concluded that the chimney jump has a significant impact on increasing leg power. On the other hand, the standing leg extension has a positive impact on increasing agility and balance.
