研究问题
However, other evidence suggests that shifting the entire F‐V curve rightward and improving power across the full continuum, regardless of initial F‐V profile, may matter more than correcting a theoretical F‐V imbalance [, ].；The authors noted that tertile‐based analyses produced comparable results; however, additional details on how the middle tertile was handled and to what extent this impacted sample size or statistical power would help contextualize this observation.；We examined whether IND training improves muscle power and functional performance more than NON‐IND training.
方法
The study was a randomized controlled trial investigating two F‐V profile‐guided training approaches.；Participants that were included in the intervention were randomly assigned to one of two groups: a group training with loads matched to their individual F‐V deficit (IND), or a group training with loads deliberately not matched to that deficit (NON‐IND).；The intervention was conducted at KU Leuven, approved by the Ethical Committee UZ/KU Leuven () and registered at ().；All participants provided written informed consent in accordance with the Declaration of Helsinki.
核心结论
Absolute load, relative load, and the number of repetitions differed significantly between the IND and NON‐IND groups (p < 0.001).；All velocity‐related variables also differed significantly between groups during both training periods (all p < 0.001).；In contrast, the set volume index did not differ between groups during either training period (PRE–MID: p = 0.340; MID–POST: p = 0.552), and neither did the session volume index (PRE–MID: p = 0.326; MID–POST: p = 0.591). ‖ 结论：The observed variability in training preferences within our sample further highlights that personal preference may be the more meaningful driver of effective training prescription.
局限
However, although the present classification pattern is broadly consistent with previous longitudinal observations suggesting a greater age‐related decline in V 0 than F 0 [], this interpretation remains speculative and warrants further investigation.；Moreover, the velocity‐deficit group showed substantial heterogeneity, with a wide range of deficit magnitudes.；However, the use of a young reference group also has limitations.
