Combined effects of very short "all out" efforts during sprint and resistance training on physical and physiological adaptations after 2 weeks of training.
Study Goal
The researchers aimed to compare the effects of resistance training, sprint interval training, and their combination on aerobic/anaerobic performance and cardiometabolic health in young adults.
Results Summary
The study found that both isolated and combined training improved physical fitness and health parameters, with concurrent training (CTG) showing the most comprehensive benefits.
Population
Young, physically active adults.
Effective Dosage
6-12 "all out" 5-second efforts per session, 3 days/week, with 24-second recovery intervals (~13 min/session).
Duration
2 weeks.
Interactions
None mentioned.

PURPOSE: The aim of this study was to compare the combined effects of resistance and sprint training, with very short efforts (5 s), on aerobic and anaerobic performances, and cardiometabolic health-related parameters in young healthy adults. METHODS: Thirty young physically active individuals were randomly allocated into four groups: resistance training (RTG), sprint interval training (SITG), concurrent training (CTG), and control (CONG). Participants trained 3 days/week for 2 weeks in the high-intensity interventions that consisted of 6-12 "all out" efforts of 5 s separated by 24 s of recovery, totalizing ~ 13 min per session, with 48-72 h of recovery between sessions. Body composition, vertical jump, lower body strength, aerobic and anaerobic performances, heart rate variability (HRV), and redox status were evaluated before and after training. Total work (TW), rating of perceived exertion (CR-10 RPE) and mean HR (HR RESULTS: Maximum oxygen consumption (VO CONCLUSIONS: RT and SIT protocols with very short "all out" efforts, either performed in isolation, or combined, demonstrated improvement in several physical fitness- and health-related parameters. However, CT was the most efficient exercise intervention with improvement observed in the majority of the parameters.
