Abstract

Background: Physical fitness is a condition where the human body is able to perform daily activities without experiencing excessive fatigue. Physical exercise is one way to achieve physical fitness. Calisthenics is one of the strength exercises that utilize body weight as resistance to increase muscle strength. Previous research has shown that strength training can increase the explosive power of leg muscles measured through vertical jumps.Objective: Knowing the effect of calisthenic exercises on the explosive power of the leg muscles.Methods: Experimental research with quasi experimental design and methods of pre-test and post-test nonequivalent control group. The subjects were 37 active students of Diponegoro University, Semarang who were selected by purposive sampling and grouped into two groups. The control group without treatment (n=19), and the treatment group (n=18) were given calisthenic exercises for 6 weeks. The explosive power of the limb muscles was measured before and after the intervention with the vertical jump instrument and expressed as the vertical jump score (VJ score).Results: The results showed a significant increase in VJ score (p=0.030) in the treatment group compared to the control group. There was also a significant increase in VJ score (p<0.001) before and after the intervention in the treatment group.Conclusion: Calisthenic exercises for 6 weeks can increase muscle explosive power in the young adult age group.

Abstract

Background: Agility is one of football's most critical anaerobic capacities. One component is the ability to change direction. Players change direction (Change of direction speed / CODS) every 2-4 seconds. Agility is influenced by several things, including speed and limb muscle explosive power, and is related to aerobic capacity, namely VO2 Max (maximum oxygen consumption) in the Running economy aspect. It is necessary to research the relationship between VO2 Max, speed, and explosive power of limb muscles with agility in soccer playersObjective: Knowing correlation between VO2 Max, speed, and limb muscle explosive power with agility in soccer players.Methods: Twenty-seven male players (Diponegoro Muda PS Undip) were involved in this study (mean±SD; age 13.22 ± 0.18 years, weight 46.78 ±1.67 kg, height 158± 1.88 cm). This research is a correlational study using a cross-sectional design. Each player will be measured VO2 Max with the Multistage Fitness Test, speed with the 20-meter sprint test, the explosive power of the limb muscles with the surgent jump test, and agility (CODS) using the Illinois agility test. The hypothesis test used is Spearman's hypothesis test and linear regression test.Results: Spearman correlation test found a strong relationship between VO2 Max and agility (r=-0.743; p= <0.001), there was a moderate relationship between speed and agility (r=0.556; p== 0.003), there was a strong relationship between muscle explosive power limbs with agility (r=-0.766; p= <0.001), and the results of linear regression of variables VO2 Max, speed, limb muscle explosive power on agility showed a strong relationship (r=0.806; r2= 0.650; p=<0.001).Conclusion: Conclusions: VO2 Max correlates with agility; speed correlates with agility; limb muscle explosive power correlates with agility; and the variables of VO2 Max, speed, and limb muscle explosive power have a relationship with agility.
