Training volume increases or maintenance based on previous volume: the effects on muscular adaptations in trained males.
This study investigated the effects of increasing previous resistance training (RT) weekly set volume by 30% (G30) and 60% (G60) on muscle hypertrophy and strength. Fifty-five resistance-trained men were randomly allocated to the experimental groups, whereas 29 completed the study, as follows: control group (CON): n = 10, G30: n = 10, and G60: n = 9.

We assessed pre- and poststudy thigh region-of-interest fat-free mass (ROI-FFM), anterior thigh muscle thickness (MT) at two sites: proximal (PMT) and distal (DMT) and their sum (ΣMT), one-repetition maximum (1RM), and strength-endurance via repetitions to failure (RTF) at 70% of 1RM. ROI-FFM and MT demonstrated a significant increase from pre- to posttraining (main time effect, P < 0.001) (ΔΣMT CON: 1.07 cm, G30: 0.76 cm, and G60: 0.70 cm; ΔROI-FFM CON: 1.57 kg, G30: 0.47 kg, and G60: 1.55 kg). All groups increased back squat 1RM (P < 0.0001). However, the main group effect (P < 0.0268) indicated that the CON group showcased a greater overall 1RM (174.7 kg), than the G30 (159.0 kg) and G60 (149.0 kg). Only the G30 group increased RTF at the posttest (CON: 0.13 reps, G30: 5.45 reps, and G60: -0.41 reps) (P < 0.0263).

期刊介绍：
The Journal of Applied Physiology publishes the highest quality original research and reviews that examine novel adaptive and integrative physiological mechanisms in humans and animals that advance the field. The journal encourages the submission of manuscripts that examine the acute and adaptive responses of various organs, tissues, cells and/or molecular pathways to environmental, physiological and/or pathophysiological stressors. As an applied physiology journal, topics of interest are not limited to a particular organ system. The journal, therefore, considers a wide array of integrative and translational research topics examining the mechanisms involved in disease processes and mitigation strategies, as well as the promotion of health and well-being throughout the lifespan. Priority is given to manuscripts that provide mechanistic insight deemed to exert an impact on the field.
