THE EFFECT OF ISOTONIC STRENGTH EXERCISE ON LEMB MUSCLESTRENGTH IN 11TH GRADE MALE STUDENTS OF SMA NEGERI 1 TONDANO

Abstract

The problem in this study: Is there an effect of isotonic strength training on leg muscle
strength in 11th grade male students at SMA Negeri I Tondano.Research Objectives: To
determine the effect of isotonic strength training on leg muscle strength in 11th grade male
students at SMA Negeri I Tenga.The research design used a randomized control group pre and
post test design. The population used was 70 11th grade male students at SMA Negeri I
Tondano. A sample of 20 people was taken at simple random. The instrument used to retrieve
data is a Leg dynamometer. The data analysis technique used is the Independent t-test statistic at
a significance level of α = 0.05.The results showed that the tested research hypothesis rejected
the null hypothesis (Ho) meaning the alternative hypothesis (Ha) was accepted with the
following test results: There is an effect of isotonic strength training on leg muscle strength in
class II students of SMA Negeri I Tondano where F count = 5.499 > from F table = 2.101, at a
significance level of α = 0.05.Research conclusion: There is an effect of isotonic strength
training on leg muscle strength in 11th grade students of SMA Negeri I Tondano.
