The Relationship between Abdominal Muscle and Legs Power with Turning Time on 100 Meters Free Style Swimming

摘要

The study was aimed to investigate the relationship between abdominal muscle and legs power with the return time on 100 meters free style swimming. The study was set as a descriptive correlation study that involved 10 members of UKM Aquatic BS UPI by using purposive sampling technique. Measurement tool to measure the power of abdominal muscle is sit up test in 30 seconds, meanwhile legs power was tested by force flat form tool and by measuring return time by using stopwatch. Based on the statistical analysis, it was revealed that there is a negative relationship between abdominal muscle power with the return time with significant value 0.01 < 0.05 (Ho is rejected). In addition, there is also a negative significant relationship between legs power with return time on 100 meters free style swimming with significant value 0.000 < 0.05 (Ho is rejected). The effects of abdominal muscle and legs power to swimming return time is up to 88.1%, while the rest 11,9% is affected by other variables.
