suggested that a plateau of hypertrophic adaptations might occur after a certain point of volume, and moreover, the authors hypothesized the possibility of a decline in these adaptations when increasing training volume beyond that point. While lacking in empirical evidence, it is possible that the dose-response relationship between RT volume and muscle hypertrophy follows an inverted U-shaped curve, whereby excessive RT volume would lead to negative adaptations. A recent study that tested the effects of German Volume Training provides further insights on the topic (2). The researchers compared two groups, of which, one performed 31 sets per training session and the other 21 sets per training session. Following six weeks of RT, increases in trunk and arm lean body mass favored the lower-volume, 21-set group. These findings suggest that volume should be increased only up to a certain point, and anything above might actually impair recovery. Curiously, no significant increases in muscle thickness were found across groups; however, a limitation is that the study lasted only 6 weeks. Currently, there is a paucity of studies that have investigated such high RT volumes, thereby opening up an avenue for future research to explore the upper threshold of RT volume for gains in muscle mass.
