THE EFFECTS OF COMBINED DRY-LAND STRENGTH TRAINING AND SWIMMING TRAINING ON BODY COMPOSITION, MUSCLE STRENGTH AND AEROBIC SWIMMING PERFORMANCE IN YOUNG SWIMMERS : A PILOT STUDY
This study aims to determine the effects of combined dry-land strength training and swimming training on body composition, muscle strength, and aerobic swimming performance in young swimmers. The participants consisted of 6 male swimmers the Assumption College Sriracha swimming club, aged 9-15 years old, experienced in swimming 1-5 years. The participants performed a dry-land strength training, 2 days/week, 1 hour per day, and swimming training, 6 days/week, 2 hour per day for 12 weeks. The data about body composition, muscle strength, and aerobic swimming performance, were collected before and after training at weeks 4th, 8th, and 12th. The data were analyzed by using the Friedman test, Wilcoxon signed ranks test. The results showed that the young swimmers had significantly increased weight, the fat-free mass, and muscle strength after the combined dry-land strength training and swimming training. The percentage of body fat, fat mass, and critical swimming speed before training, after training weeks 4th, 8th, and 12th were not different significantly. In conclusion, combined dry-land strength training and swimming training increase muscle strength and fat-free mass in young swimmers. The athletes can use the combined dry-land strength training and swimming training could be a favorable training program for improving swimming performance in young swimmers.
