The Effect of the Sequence of Concurrent Strength and Endurance Training on Aerobic Capacity, Anaerobic Capacity and Maximum Strength of Male Adolescents

The objective of the present research was to compare the effect of the sequence of concurrent strength and endurance exercises on aerobic capacity, anaerobic capacity and maximum strength of male adolescents. 50 high school students with the average age of 17.22±0.94 years, 175.62±7.11 centimeters of height, and 62.82±7.78 kilograms of body mass were randomly chosen and divided into five groups of ten subjects - i.e. strength training (ST), endurance training (ET), strength-endurance training (SE), endurance-strength training (ES) and control (CO). Maximal aerobic capacity (VO2max) was assessed by a 1600-meter run, lactic anaerobic capacity and fatigue index by RAST test, alactic anaerobic capacity by vertical jump test, strength by one-repetition maximum test (1RM), agility by Illinois Agility Run test and muscle endurance by sit-ups test. Based on the findings of the research, a significant increase was observed in VO2max of the endurance and concurrent training groups. Alactic anaerobic capacity of the five groups did not have a significant increase. A significant increase was observed in the lactic anaerobic capacity and fatigue index in the strength training group. According to the findings of the research, relative maximum strength increased significantly in the strength and endurance-strength training groups. Moreover, the increase in agility and muscle endurance was significant in the four experimental groups. Combining strength and endurance exercises improves strength and endurance and adding strength training to the endurance training program does not risk the improvement of VO2max. Also the endurance-strength sequence of training has the greatest effect on maximum strength and agility.
