Effects of different velocity loss thresholds on passive contractile properties and muscle oxygenation in the squat exercise using free weights

The current study assessed the impact between different velocity loss thresholds on changes in the muscle contractile properties and muscle oxygenation after a single resistance training session. 30 physically-active men participated in a cross-over study performing three sets of the squat exercise...

Contractile properties of the knee extensor muscles were tested using Tensiomyography. In addition, muscle oxygenation was continuously measured from baseline until the end of the exercise session. The Vastus Lateralis showed a significant Moment by Condition interaction in Time Delay (p=0.044), Muscle Displacement (p=0.001), and Contraction Velocity (p=0.007), with greater reductions in VL40. During the execution, the oxygenated haemoglobin and the tissue oxygen index decreased, while the deoxygenated haemoglobin increased (Moment as the main effect, p<0.05), but without a Moment by Condition interaction. In addition, VL40 showed a lower deoxygenation slope in Set 1 (-0.468 %·s-1, p= 0.001) and Set 3 (-0.474 %·s-1, p= 0.037) as well as higher losses in Set 1 (-41.50%, p=0.003), Set 2 (-41.84%, p= 0.002), and Set 3 (-62.51%, p<0.001). Finally, the recovery slope and increment during the first minute after each set were not significantly different between conditions.
