The study purpose was to evaluate antecedent binaural stimulation (ABS) on maximal aerobic physical performance. Twenty‐two healthy, physically active subjects, 21–34 years, randomly received one of two preparations for each session: 15 min of quiet (BLANK) or percussive sonic driving at 200+ beats per minute (bpm) using a recorded compact disc (FSS, Mill Valley, CA) with headphones (ABS). Baseline HR, blood pressure (BP), and breathing frequency (f br ) were obtained. During each condition, HR and f br were recorded at 3‐min intervals. The graded maximal treadmill testing was administered immediately postpreparation session on separate days, with at least 48 h rest between sessions. There were significant differences in the antecedent period means between the two conditions, ABS (HR: 70.2 ± 10.7 bpm; f br : 18.5 ± 3.3 br min −1 ; BP: 134.5/87.9 ± 13.6/9.2 mm Hg) and BLANK (HR: 64.6 ± 7.9; f br : 14.3 ± 2.9; BP: 126.7/80.3 ± 12.1/8.6). Differences were noted for each 3‐min interval and pre‐ postantecedent period. The maximal graded exercise test (GXT) results showed that there was a small but significant ( P < 0.05), increase in maximal VO 2 in the ABS (49.8 ± 6.8 ml · kg −1 · min −1 ) vs. BLANK (46.7 ± 8.7) conditions. Related to that finding was a slight increase (0.5 min) in time to exhaustion ( P < 0.05). There were no significant differences in HR or RPE ( P > 0.05). There may be a latency to ABS related to entrainment or imagery‐enhanced warm‐up. Am. J. Hum. Biol. 12:558–565, 2000. © 2000 Wiley‐Liss, Inc.
