Maximal strength, power, and aerobic endurance adaptations to concurrent strength and sprint interval training

Purpose This study was designed to examine whether concurrent sprint interval and strength training (CT) would result in compromised strength development when compared to strength training (ST) alone. In addition, maximal oxygen consumption ( V O 2 max) and time to exhaustion (TTE) were measured to...

Description
Summary:Purpose This study was designed to examine whether concurrent sprint interval and strength training (CT) would result in compromised strength development when compared to strength training (ST) alone. In addition, maximal oxygen consumption ( V O 2 max) and time to exhaustion (TTE) were measured to determine if sprint interval training (SIT) would augment aerobic performance. Methods Fourteen recreationally active men completed the study. ST ( n  = 7) was performed 2 days/week and CT ( n  = 7) was performed 4 days/week for 12 weeks. CT was separated by 24 h to reduce the influence of acute fatigue. Body composition was analyzed pre- and post-intervention. Anaerobic power, one-repetition maximum (1RM) lower- and upper-body strength, V O 2 max and TTE were analyzed pre-, mid-, and post-training. Training intensity for ST was set at 85 % 1RM and SIT trained using a modified Wingate protocol, adjusted to 20 s. Results Upper- and lower-body strength improved significantly after training ( p   0.05). V O 2 max increased 40.9 ± 8.4 to 42.3 ± 7.1 ml/kg/min ( p
