TL;DR
Investigation of contraction mode-dependent MRI responses in lower-leg muscles using quantitative T2*, T2, and T2' measurements provides insight into muscle-specific MRI responses and may inform the optimization of rehabilitation strategies.
Blood flow restriction (BFR) can modify surface electromyographic (sEMG) amplitude during exercise, but it remains unclear whether these changes differ between the power and recovery phases of cycling and whether whole-cycle temporal and co-contraction descriptors also change. Because sEMG does not directly measure...
The purpose of this study was to examine early post-exercise changes in quadriceps muscle thickness after a protocol of consecutive isokinetic concentric leg extension muscle actions and determine whether these changes are muscle- or site-specific. Fifteen young adults (14 males, 1 female) completed 50 maximal unilater...
Isokinetic testing at different velocities resulted in significant changes in SmO 2 and tHb, whereas muscle strength level did not significantly influence these responses, whereas muscle strength level did not significantly influence these responses.
Skeletal muscle is a living, perfused soft tissue whose viscoelastic behavior is shaped by both voluntary contraction and hemodynamic state. However, the independent and superimposed contributions of contractile loading and blood flow restriction (BFR) have not been quantified simultaneously in real time. Twenty-six he...
INTRODUCTION Repeated sprint training in hypoxia (RSH) or with blood flow restriction (RS-BFR) are known to enhance the repeated-sprint ability. However, studies directly comparing their underlying molecular mechanisms are scarce. METHODS Here we used a comprehensive approach combining pre- and post-intervention test...
BACKGROUND Increased inspiratory loading increases oxygen consumption and metabolic demand in the respiratory muscles, affecting muscle oxygenation. However, evidence regarding different inspiratory muscle training (IMT) intensities on intercostal muscle oxygenation remains limited. This study compared acute effects of...
