What this work gives Aellic
The fibre-level follow-up to schumann2022 , and the one place where a small interference effect does show up: 15 studies, SMD −0.23 for overall muscle fibre hypertrophy (95 % CI −0.46 to −0.00; p = 0.050), −0.34 for type I (p = 0.078) and −0.13 for type II (p = 0.315). This is also the source for the running-versus-cycling difference: type I fibres were negatively affected when the aerobic work was running (SMD −0.81; 95 % CI −1.26 to −0.36) but not cycling. The authors call the contrast with whole-muscle findings “intriguing” rather than resolved.
Correction of 26 July 2026
The findings of this entry and of schumann2022 were the wrong way round. What stood here — no whole-muscle deficit, only explosive strength affected — is the result of schumann2022 ; this paper measures fibre size only and explicitly narrowed its protocol to that outcome. The whole-muscle sentence appears in its background, as a reference to the earlier work. The added condition “and only at high volumes” was in neither paper: the moderator that mattered in schumann2022 was same-session execution, not volume.
The entry on the register was wrong. It was not replaced but kept — with what holds instead standing next to it.
