Physical Fitness of Elementary School Students: Which is better, Circuit Training A and Circuit Training B?

The problem in this study is that the level of students' physical fitness is still relatively low, so it is necessary to have an optimal exercise program for physical fitness. The purpose of this study was to determine the level of fitness after doing Circuit A and Circuit B. The method used was a quasi-experimental method with a Nonequivalent Control Group Design research design. Where in this design there are two groups, namely one experimental group and one control group, and 60 students were divided into two parts and sampled for the experimental group using ordinal pairing technique. The instrument used is TKJI for ages 10-12 years. The results of this study: 1) Circuit A, r arithmetic 0.908 > r table 0.3610 with = 0.05, N = 30 there is a significant effect. 2) Circuit B, r count 0.8903> r table 0.3610 with = 0.05, N= 30 there is a significant effect. 3) Different test with t count 2.08 > t table 1.671 = 0.05, N = 60 there is a difference. So circuit training A is better in improving students' physical fitness. So that in this research it is hoped that in the future it can be used as a reference for the circuit training A training program as a reference for physical fitness training at the elementary school level.
