Purpose: today, the record is one of the major concerns of coaches in competitive swimming. Therefore, finding the proportional type of resistance training as an essential factor affecting physical fitness and performance, is highly important. The purpose of this study was to investigate the effect of four weeks total body resistance training on muscular function and performance of young female swimmers.
Methods: Twelve college-level female swimmers were divided into Control and TRX group. The control group performed swimming protocol while the experimental group carried out eight swim like TRX addition to swimming program. Muscular function was measured using isokinetic device and swimming performances was measured by the record they reached and the number of hands and feet strokes during 25 and 50 m breaststroke swimming. Independent T-test was used to analyze the research data after subtracting the pretest from the post-test.
Results: Both groups have shown significance improvement in 25 m swimming record but there wasn’t significant difference between groups (P = 0.289). Moreover, Number of strokes decreased significantly in TRX group (P = 0.31). Muscular function factors in 25 m and total work in 50 m has shown improvement in TRX group (P ≤ 0.05). Conclusion: In general, combination of TRX with swimming training is most effective than swimming alone to improve swimmers performances.
Conclusion: In general, the results of this study indicate that the combination of TRX with swimming training is more suitable for improving swimmers' performance. It is also recommended that swimmers take advantage of this training method due to the principle of Specificity training and easy use.
