The Faculty of Physical Education and Sports is responsible for teaching sports, of which swimming is a very important subject. Swimming is a sport that operates in an aquatic environment. Due to the effects of whole-body movement, especially the movement of the legs and arms, swimmers can overcome underwater distances at certain speeds. The comparison results show that most of the indicators in the experimental group, after the post-experiment classification, are higher than those before the experiment. There are 6/6 evaluation indicators with x^2 calculated >
x^2 table = 5.991 at the probability threshold P<
0.05, so the difference between the observed frequencies is statistically significant. This proves that the physical development exercises developed by the topic are reasonable, contributing to improving the physical strength of students in the experimental group.The Faculty of Physical Education and Sports is responsible for teaching sports, of which swimming is a very important subject.
