Blood Lactate During Recovery From Intense Exercise: Impact Of Inspiratory Loading

“It has long been suggested that inspiratory muscle activity may impact blood lactate levels during the recovery from dynamic exercise. In this study, we tested the hypothesis that inspiratory muscle activation during recovery from intense exercise would contribute to Lactate clearance, thus leading to reduced blood lactate levels.:

Conclusion:

“These data are consistent with the notion that inspiratory muscles may be net consumers of lactate during recovery from intense exercise.”

Inspiratory Resistive Loading After All-Out Exercise Improves Subsequent Performance

Previous studies have shown that post-exercise inspiratory resistive loading reduces blood lactate. In this study, we tested the hypothesis that inspiratory resistive loading during recovery could improve subsequent exercise performance.

Conclusion:

“Inspiratory resistive loading during recovery from all-out maximal-intensity exercise decreases blood lactate and perception of leg effort with beneficial effects on peak and mean power on subsequent supra-maximal exercise in healthy males. Our results provide rationale for using post-exercise inspiratory resistive loading as an ergogenic aid and future studies should be conducted to better evaluate the mechanisms responsible for this effect.”
