During each testing session, athletes first completed a ramped arm-ergometer exercise test to<br> exhaustion for the determination of peak work rate and peak oxygen uptake. Following a 30 minute break,<br> athletes completed a sub-maximal arm-ergometer test at 20, 40, 60, and 80% of peak work rate. Inspiratory<br> capacity maneuvers were performed in the final minute of each stage to determine end-expiratory lung<br> volume (EELV) and calculate end-inspiratory lung volume (EILV). Breath-by-breath cardiopulmonary<br> indices were recorded throughout both exercise tests. On a separate day, athletes were assessed for time<br> to complete a field-based 20x20 metre repeated sprint test.<br> <strong>RESULTS</strong>: Following RMT, there were increases in peak work rate (69&plusmn;22 post vs. 60&plusmn;20 W pre, p=0.03),<br> oxygen uptake (20.3&plusmn;5.9 vs. 17.6&plusmn;5.0 mL/kg/min, p=0.04), and minute ventilation (54&plusmn;18 vs. 46&plusmn;12 L/min,<br> p=0.03). Dynamic hyperinflation was present during all tests as evidenced by an increase in EELV with<br> increasing exercise intensity; however, during post-RMT testing both EELV and EILV were significantly<br> lower than pre-RMT throughout exercise (p&lt;0.05). At follow-up, no indices were different from post-RMT.<br> Field-based repeat sprint performance was unchanged by RMT.<br> <strong>DISCUSSION</strong>: RMT enhances exercise capacity in athletes with tetraplegia. Whether this is due to an<br> increased peak ventilation or the circulatory benefits of an enhanced respiratory muscle pump, lower<br> operating lung volumes, and/or an attenuation of the respiratory muscle metaboreflex remains to be<br> determined.</p></description> </descriptions> </resource>
