Speed and power are the most important physical components in badminton with the current rally point system. The purpose of this study was to determine the effect of badminton shadow training on power and speed. This research used experimental research with randomized group pre-test and post-test design. The subjects of this study were male students IKOR unesa 2018 class which were randomly divided into experimental group 1 (K1) and experimental group 2 (K2) consisting of 10 people per group. K1 group was given badminton shadow training with 1: 1 interval training method and K2 group with 1: ½ interval training method with 15 seconds training time. The power test is performed using jump MD and the speed test is carried out with a 30 Meter sprint test. Paired t test results were significant (p <0.05) on power (p = 0.035) and speed (p = 0.006) at K1, whereas at K2 were also significant at power (p = 0,000) and speed (p = 0.014). Independent sample t test results were not significant at the power (p = 0.190), while the speed was also not significant (p = 0.165). In conclusion, badminton shadow training can increase power and speed with both 1:1 or 1: ½ interval training ratios. Shadow badminton training with 1: ½ interval training is more to increase power and speed because on average the results are better than shadow badminton training with 1:1 interval training.

The purpose of this study is to analyze the effects of cardio exercise and tabata method on body weight, body fat, and physical fitness. This study applied experimental design with pretest and posttest. A total of 27 respondents were all males and had BMI over 25.0 (overweight and obese). They were then divided into 3 groups: control (K1), cardio group (K2) and Tabata group (K3), each consisting of 9 individuals. K1 did not receive any intervention. While K2 and K3 were received six-weeks interventions, three times per week. K2 performed jogging and skipping training at 55% -70% HRmax during 40-minutes. While K3 performed squat trust and skipping 8 sets at 90%-95% HRmax. There were significant differences between groups for all body composition measures. In conclusion, Tabata method represents an effective way in reducing body weight and body fat, but it is no better than cardio exercise in improving physical fitness.

Eccentric activity can cause pain due to muscle damage and fatigue. Tired and damaged muscular state will degrade athletes' performance during a competition. Glutamine supplements are known to maintain plasma protein levels and can also improve muscle weakness due to inflammation that occurs after eccentric activity. The purpose of this study was to prove the effect of glutamine supplementation on the reduction of muscle fatigue after eccentric activity based on muscle strength and joint ROM. The subjects of this study were students of PJKR, IKIP Budi Utomo, who were randomly divided into 2 groups, the control group (K1) and treatment group (K2), each consisting of 22 respondents. The design of this research is randomized grsoup pre-test and post-test design. The eccentric activity performed was drop jumps on the bench with a height of 0.5 meters. Glutamine was administered orally after eccentric activity with a dose of 0.4 grams/kg BW in 450 ml water mineral 3 times (3 days). Measurement of Leg muscle strength was performed using Back and Leg Dynamometer by pulling with all the strength using leg muscles, whereas ROM measurements were measured using a goniometer performed on the knee joint in a passive way. The result of measurement obtained the mean of muscle strength of control group 63.7 ± 17.0 kg and treatment group 81.1 ± 17.0 kg at 72 hours. While result of ROM measurement obtained the mean of control group 124.3 ± 3.2 degrees and treatment group 131.7 ± 4.1 degrees at 72 hours. The analysis showed that glutamine administration in treatment group after eccentric activity increased leg muscle strength with p=0.000, and also increased knee joint ROM with p=0.000 at 72 hours after eccentric activity. In conclusion, glutamine administered with a dose of 0.4 gram/kg BW/day can increase leg muscle strength and knee joint ROM at 72 hours after eccentric activity.
