Introduction: Concurrent training emphasizes the combination of strength and endurance workloads, which can be systematically dosed, distributed, and monitored within an intrasession, intersession, or intramicrocycle. This approach contributes to neuromuscular and cardiovascular adaptations and optimizes swimming performance.
Objective: To determine the effects of concurrent training on physical fitness parameters and specific performance in young swimmers competing in 50 m and 100 m freestyle events.
Materials and Methods: Twelve swimmers (11.75±1.28 years old; 150.81 ± 9.92 cm; 43.89 ± 9.37 kg), body composition was evaluated using the kinanthropometry technique, the 20-meter Course Navette test (20m-SRT) to estimate the indirect VO2max, maximum strength by three repetitions maximum (3RM) in squat and bench press, maximum strength by three repetitions maximum (3RM) in sit-up and bench press, and maximum strength by three repetitions maximum (3RM) in sit-up and bench press, maximum strength by three repetition maximum (3RM) in squat and bench press, neuromuscular power by countermovement jumps (CMJ), Abalakov (ABK) and Drop Jump (DJ), and swimming performance in 50 and 100 meters in the crawl style.
Results: Statistically significant changes were observed in sitting height (p = 0.006), arm span (p = 0.027), muscle mass (p = 0.023), VO2max (p = 0.032), maximal strength, and neuromuscular power, along with improvements in 50 m and 100 m freestyle performance tests.
Conclusion: Changes in sitting height and arm span may be key factors in improving swimming performance. Additionally, increases in VO2max and maximal strength may contribute to better execution of high intensity efforts in 50 m and 100 m freestyle events.
