Abstract

The purpose of this study was to determine the effect of Pec Deck Flyes and Cable Crossover training on Arm Muscle Strength and Forehand in male tennis players. This type of research is an experimental study using "Randomized Control Group Pretest-Posttest Design". The population in this study were 30 male tennis players. Then divided into 3 groups, experimental group I was given Pec Deck Flyes treatment, experimental group II was given Cable Crossover treatment and the control group was given conventional treatment. To determine the strength of the arm muscles, each subject was given a push-up test for 30 seconds and for forehand results, the subjects were given the opportunity to hit 15 balls with the forehand technique. Based on the Multivariate analysis, testing the equality of variance-covariance in both dependent variables together using the Box's Test Of Equality Of Covariance Matrices, a significance value of 0.130> 0.05 was obtained, because the Box's value was greater than alpha 0.05, then the variance-covariance were the same. Testing the equality of variance-covariance on both dependent variables individually using the Levene Test Of Error Variances number for arm muscle strength obtained a significance value of 0.134> 0.05 and a significance value for forehand results of 0.296> 0.05, because the significance value is greater than alpha 0.05. It can be concluded that both dependent variables have different Variance-Covariance Matrices in the independent variable group. The difference between groups using the Wilks' Lambda test obtained a significance value of 0.00 <0.05. Because the Wilks' Lambda significance value is smaller than alpha 0.05, it can be concluded that there is a difference in the increase in arm muscle strength and forehand results.Keywords: Training, Pec deck Flyes, Cable Crossovr, Arm Muscle Strength, and forehand.

Abstract

Concentration is a vital aspect of martial arts such as Kempo, which requires quick responses, technical precision, and mental composure. Based on observations and interviews with coaches and athletes from the Indonesian Kempo Federation at Graha BSS, Narmada, a problem of low concentration levels was identified, which affects the athletes' performance and achievement. Therefore, this study was conducted to examine the effect of meditation training on improving athletes’concentration. The research employed a quantitative approach with a one-group pretest-posttest experimental design, without a comparison group. The population consisted of 30 athletes, with a sample of 20 athletes selected using purposive sampling based on specific criteria. Meditation sessions were conducted over a onemonth period, totaling 12 meetings with a frequency of three sessions per week. The instrument used was the Concentration Grid Test (CGT), a measurement tool proven to be valid and reliable. Data collection techniques included documentation and performance-based testing to assess concentration levels before and after the intervention. The data were processed through editing, coding, saving, tabulating, and cleaning, and then analyzed using parametric statistics, including normality tests (Kolmogorov-Smirnov and Shapiro-Wilk), a homogeneity test (Levene’s Test), and hypothesis testing using the paired samples t-test. The findings showed an increase in the average concentration score from 9.45 (pre-test) to 15.15 (posttest), with a mean difference of 5.7 points. The t-test resulted in a significance value of 0.001 (< 0.05), indicating a statistically significant difference, meaning meditation training had a positive effect on the athletes’ concentration. Therefore, it can be concluded that “Meditation training has a positive influence on improving the concentration of athletes in the Indonesian Kempo Federation at Graha BSS, Narmada.
