Enhanced ventilatory and exercise performance in athletes with slight expiratory resistive loading.
We determined the cardiorespiratory and performance effects of slight (1.5-3.0 cmH2O) expiratory resistive loading (ERL). Twenty-eight highly fit [peak O2 uptake (VO2 peak) = 63.6 +/- 1.3 ml . kg-1 . min-1] athletes (age = 33.5 +/- 1.3 yr) performed paired VO2 peak cycle ergometer tests (control vs. ERL). End-expiratory lung volume was separately determined in a subset of subjects (n = 12) at s...
متن کاملEffect of chronic resistive loading on hypoxic ventilatory responsiveness.
Depression of ventilation mediated by endogenous opioids has been observed acutely after resistive airway loading. We evaluated the effects of chronically increased airway resistance on hypoxic ventilatory responsiveness shortly after load imposition and 6 wk later. A circumferential tracheal band was placed in 200-g rats, tripling tracheal resistance. Sham surgery was performed in controls. Ve...
متن کاملEffect of Expiratory Resistive Loading in Expiratory Muscle Strength Training on Orbicularis Oris Muscle Activity
[Purpose] The purpose of this study was to elucidate the effect of expiratory resistive loading on orbicularis oris muscle activity. [Subjects] Subjects were 23 healthy individuals (11 males, mean age 25.5±4.3 years; 12 females, mean age 25.0±3.0 years). [Methods] Surface electromyography was performed to measure the activity of the orbicularis oris muscle during maximum lip closure and resisti...
متن کاملThe Relationship between the Isocapnic Buffering Phase and Ventilatory Threshold in Endurance Athletes and Team Sport Athletes during an Incremental Exercise Test
Background. There is sparse literature examining the ICB phase of aerobic- and anaerobic-trained athletes. Measurements of ICB phase values of athletes can help to evaluate the sport’s physiological demands and understand the physiological adaptations in response to physical training. Objectives. The purpose of this study was to examine the relationship between the isocapnic buffering (IC...
متن کاملNitric oxide production in the ventilatory muscles in response to acute resistive loading.
The effect of muscle activation on muscle nitric oxide (NO) production remains controversial. Whereas NO release increases in in vitro activated muscles and in vivo limb muscles, diaphragmatic NO synthase (NOS) activity declines after 3 h of inspiratory resistive loading (IRL). We tested in this study the hypotheses that acute IRL decreases diaphragmatic NO derivatives levels and reduces protei...
