- The study examined the effects of different velocity loss (VL) thresholds during resistance training (RT) on concurrent training (CT) adaptations.
- Forty-one moderately trained men were divided into four groups: CT with RT at 0% VL (VL0), 15% VL (VL15), 40% VL (VL40), or endurance training (ET) alone.
- Training lasted 8 weeks, with CT groups performing squat-based RT followed by endurance running, while ET focused solely on endurance training.
- VL40 showed the greatest muscle mass gains among CT groups, while ET showed no changes.
- Maximal aerobic speed (MAS) improved in all groups, with ET showing the highest gains. Lower VL in CT correlated with higher effect sizes for MAS.
- VL15 and VL40 groups achieved greater 1RM strength gains compared to ET.
- ET alone impaired neuromuscular function and did not improve strength, while CT improved both strength and endurance.
- Fatigue during RT may attenuate endurance adaptations, whereas ET enhanced aerobic performance but reduced strength-related outcomes.
