| Description | Concurrent strength and endurance training is widely performed by recreationally active people as well as professional athletes. This type of training is often accompanied by a negative effect of endurance training on strength training-related outcomes, termed an Interference effect. We examine whether concurrent training attenuates strength training adaptation compared to strength training alone. Twenty recreationally active men were included in the study and randomized to concurrent training or resistance training groups. Fifteen participants completed the 12-week study protocol (mean age 23.4 ± 3.0, mean weight 79.9 ± 10.0, mean height 180.8 ± 7.0). Both groups improved maximal dynamic strength (1 repetition maximum squat +16.1 % vs. +16.9 % for concurrent and strength training groups, respectively (p = 0.954), and bench press +8.5 % vs. +9.8 % for concurrent and strength training groups, respectively (p = 0.602)). Maximum anaerobic power was also improved to a similar extent (+9.2 % vs. +7.8 % for concurrent and strength training groups, respectively (p = 0.862)). The results did not show statistically significant differences between groups regarding adaptation improvement. These results suggest that in recreationally active young men, concurrent endurance and strength training can be as effective as strength training in improving strength-related outcomes. |
