The purpose of this study was to determine whether hyperoxic gas inhalation following anaerobic exercise hastens recovery or enhances subsequent performance. Eight male and four female university students performed two bouts of bench press exercise to exhaustion at 70% of 1RM (performance test: PT-1 and 2). Interval of two exercises was separated by a 30 min recovery period during which the subjects breathed either room air (NOX) or hyperoxic gas (60% O2 in nitrogen: HOX) for 20 min (1-21 min of recovery time). The entire procedure was repeated on each subject using the opposite gas on another day. The work load in PT was 41.3+10.9 kg (70.2% of 1RM). The numbers of repetition of bench press in NOX and HOX conditions were 15.0+4.7 and 14.5+4.4 repetitions in PT-1, and 13.7+4.1 and 13.0+4.0 repetitions in PT-2 (NOX, -8.7%: HOX, -10.3%), there were no significant differences between both conditions, respectively. The changes of blood lactate concentration and its peak values (NOX, 4.00+1.08 mM: HOX, 3.90+0.88 mM) during recovery periods were not significantly different between NOX and HOX conditions. In conclusion, these data indicate that hyperoxic gas inhalation offers no advantages on recovery from exhaustive anaerobic exercise or on subsequent exercise performance.
