Pengaruh Latihan Lari Interval Terhadap Vo2max Mahasiswa Program Studi Ilmu Keolahragaan Universitas Singaperbangsa Karawang

This study aims to determine whether there is a relationship between leg muscle explosive power and leg length on high jump results in KOP athletics students of Jakarta State University. The design of this study is a quantitative study that uses a series of tests, namely the measurement of leg length, vertical jump test and flop style high jump test. There were a total of 20 subjects studied and only 18 met the instrument test. Data processing using SPSS version 20 with Correlation found a correlation result of leg muscle explosive power of 0.673 and a significance value of 0.000 where the significance value was smaller than 0.05 indicating a strong relationship between leg muscle explosive power and high jump results. Then based on the results of the correlation test the correlation result of the length of the limb of 0. 818 and the significance value of 0.000 where the significance value was smaller than 0.05 The variable correlation value shows a positive value and shows a very strong relationship between leg length and high jump results. Then based on the results of the f test, it is known that the significance value in this f test has a value of 0.000 less than 0.05 so it can be concluded that there is a relationship between the explosive power of the leg muscles and the length of the tugkai together with the high jump results of KOP athletics students of Jakarta State University.

“…Agility plays a special role in physical mobility. Agility is not a single physical component but is composed of components of coordination, strength, flexibility, reaction time and power (Sahabuddin et al, 2020). The problem of body size and body parts owned by each athlete is one of the influential factors in sports performance.…”

Ability 50 Meters Sprint In Terms Of The Performance Of Leg Length And Weight Of SDS Bakau Estate Students

S.,

Hasrudin,

Hasniah

et al. 2023

This study aims to determine the performance of leg length and body weight in the ability to sprint 50 meters of SDS Bakau Estate students. This research is a quantitative descriptive study with two independent variables, namely leg length and body weight with one dependent variable sprint of 50 meters. The number of samples in this study is limited to 30 students from SDS Bakau Estate. The technique for determining the sample was by using purposive sampling, taking based on certain objectives as many as 30 students from SDS Mangrove Estate. Data analysis techniques were processed using computer assistance through the SPSS 22.0 program. Based on the data analysis, the results obtained: (1) There is a leg length performance with a 50-meter sprint ability of SDS Bakau Estate students, as evidenced by the value of r arithmetic ( ro ) = 0.382 (0.037 <0.05), (2) There is a weight performance with a 50 sprint ability meters at SDS Bakau Estate students, as evidenced by the value of r arithmetic ( ro ) = 0.409 (0.025<0.05), and (3) there is a performance of leg length and body weight on the 50-meter sprint ability of SDS Bakau Estate, as evidenced by the calculated R-value obtained R = 0.533, R2 value = 0.285 or 36.6% and calculated F value = 5.368 (0.011<0.05).

“…Mentions that running speed ability is confined by certain factors, including Anthropometry (Cahyono et al, 2017) Sahabuddin et al, 2020. The physical human features like the comparison of leg length, height and arm length have significance in increasing the speed yet it cannot be trained (Juliyanto, 2016;Pratama & Nurrochmah, 2022).…”

Effects of S-Curve Runs and Sprint In-Out Exercise Methods Against The Increase of Speed, in 100 Meters Sprint Observed from Foot Length and Height Ratios

Sinurat,

2023

The purpose of this study was to find the effect of differences between S-Curve Runs and Sprint In-Out exercise methods against the increase of speed in 100 meters sprint; the different increases of speed in 100 meters sprints for the runners with big, medium, and small ratios of foot length and height; and the differences of interactions between S-Curve Runs and Sprint In-Out exercise methods and foot length and height ratios against the increase of speed in 100 meters sprint. This research was conducted at Chevron Football School in Pekanbaru for 8 weeks by using the experimental method of 2 x 3 factorial designs. The research population contained students of the school. Purposive Random Sampling was utilized as the sampling method included 42 students with big, medium, and small ratios of foot length and height, for each took 14 students as the samples. ANOVA was employed as the data analysis technique. Prerequisite tests of data analysis were conducted beforehand by using the sample normality test (Lilliefors Test at α = 0.05) and homogeneity of variance test (Bartlett’s Test at α = 0.05). Results of data analysis indicated that there were significant differences between S-Curve Runs and Sprint In-Out exercise methods against the increase of speed in 100 meters sprint with Fcount = 10.54758 > Ftable = 4.07 in which the effects of S-Curve Runs exercise have better improvement than Sprint In-Out exercise, with the average increases for each are 2.17 and the 1.7; there were significant differences between the runners with big, medium, and small ratios of foot length and height with Fcount = 14.16068 > Ftable = 3.22. The increase of 100 meters sprint result on samples with big ratios of foot length and height was better than samples with medium and small ratios, for each having average increase of 2:43, 1.89 and 1:51; and there was no correlation effect between the S-Curve Run and Sprint In-Out training methods and the foot length and height ratios against the increase of running speed, in which the Fcount = 0.29174 < Ftable = 3:22.
