The Effect Of Arm And Leg Muscle Strength On The 50-Meter Freestyle Swimming Speed Of Swimming Club Athletes In Pringsewu

This study aims to determine the effect of arm and leg muscle strength on the 50-meter freestyle swimming speed of Swimming Club atlhetes  in Pringsewu. This research used an experimental method with a pretest-posttest control group design. The sample consisted of two experimental groups: one focused on arm muscle strength training, and the other on leg muscle strength training. Data were collected using a 50-meter freestyle speed test. The analysis revealed that both arm muscle strength (t = 5.111 > t-table=2.201) and leg muscle strength (t = 6.046 > t-table=2.201) significantly affected swimming speed. In conclusion, arm and leg muscle strength simultaneously contribute to improving 50-meter freestyle swimming performance.
