PURPOSE: We examined the effect of @entity9882 supplementation plus @entity4388 on high-intensity cycling capacity. METHODS: Twenty males (age = 25    5 yr, height = 1.79    0.06 m, body mass = 80.0    10.3 kg) were assigned to either a placebo (P) or a @entity9882 (BA; 6.4 g  d(-1) for 4 wk) group based on power max, completing four cycling capacity tests at 110% of power max (CCT110%) to determine time to exhaustion (TTE) and total work done. A CCT(110%) was performed twice (habituation and baseline) before supplementation (with maltodextrin [MD]) and twice after supplementation (with MD and with @entity4388 [SB]), using a crossover design with 2 d of rest between trials, creating four study conditions ( @entity16803 , PSB, BAMD, and BASB). Blood pH, @entity880 , @entity3157 and base excess were determined at baseline, before exercise, immediately after exercise, and 5 min after exercise. Data were analyzed using repeated-measures ANOVA. RESULTS: TTE was increased in all conditions after supplementation (+1.6% @entity16803 , +6.5% PSB, +12.1% BAMD, and +16.2% BASB). Both BAMD and BASB resulted in significantly improved TTE compared with that before supplementation (P  <= 0.01). Although further increases in TTE (4.1%) were shown in BASB compared with BAMD, these differences were not significant (P = 0.74). Differences in total work done were similar to those of TTE. Blood @entity3157 concentrations were significantly (P  <= 0.001) elevated before exercise in PSB and BASB but not in @entity16803 or BAMD. Blood @entity880 concentrations were significantly elevated after exercise, remaining elevated after 5 min of recovery (P  <= 0.001) and were highest in PSB and BASB. CONCLUSIONS: Results show that BA improved high-intensity cycling capacity. However, despite a 6-s (   4%) increase in TTE with the addition of SB, this did not reach statistical significance, but magnitude-based inferences suggested a    70% probability of a meaningful positive difference.
