The purpose of this study was to investigate the effects of concurrent training on cardiopulmonary response, power and record level of 1500m swimming among youth swimmers. Twenty-two youth swimmers were divided into three experimental groups: concurrent (n = 7), resistance (n = 8), and endurance (n = 7) training groups. Each group trained three times a week for eight weeks, with all types of training occurring in the same session. Parameters assessed were height, weight, and power, strength, training age, maximal oxygen uptake, and training experience. All participants were fully informed about the aims of the study and gave their voluntary consent before participation. The measurement procedures were in agreement with ethical human experimentation. Subjects in the concurrent group participated for eight weeks, three days per week. First, the subjects completed 8-10 resistance-training exercises and then completed the hour of training by walking /jogging /running for up to 30 minutes on a treadmill at a prescribed target heart rate. A strand Treadmill Test was used to determine the maximal oxygen uptake, and dynamometer instruments were used to measure the strength of the leg and back. The results revealed significant increases in Grip strength for the strength group versus the endurance group and for the concurrent group versus both the strength and endurance groups. Maximal oxygen uptake for the endurance group versus both the strength and concurrent groups and for the concurrent group versus the strength group. Leg strength for the strength group versus the endurance group and for the concurrent group versus the endurance group. Back strength for the strength group versus the endurance group and the concurrent group versus the endurance group. In conclusion, the present study shows that eight weeks of concurrent strength and endurance training has beneficial effects on musculoskeletal power, maximal oxygen uptake and record level of 1500m swimming.
