The Effect of Quick Strength Training on the Agility and Leg Power of Futsal Junior Athletes

This research aimed to examine the effect of Quick Strength Training (QST) on agility and leg power. It used experimental methods with a pre-test-post-test design. A purposive sampling technique was used with several criteria. Before the treatment was executed, the 11 participants in each group were tested for their agility with the side step test and leg power with vertical jump. The 11 participants in the experimental group performed QST training program for 42 days or six weeks and the focus was carried out with an intensity of three times a week, then in the other control group, there were 11 participants, as a CON, who did not do any physical activities for 6 weeks. After six weeks of treatment, the 22 participants performed side step and vertical jump as a post-test. There was an increase in the average of their agility; CON test before treatment and test after treatment QST test before treatment and test after treatment (p=0.007). The increase in leg strength in participants is also a record for a result; CON test before treatment and test after treatment and QST pre-test with post-test (p=0.000). Agility test before treatment has similarities between CON and QST (p=0.171), but there was a post-test agility difference between CON and QST (p=0.538). There was also a difference in the pre-test leg power between CON and QST (p=0.061), and there was a post-test leg power difference between CON and QST (p=0.001). The results showed that QST increased futsal athletes' agility and leg power.
