Key result
Self-selected motivational music significantly increased average power output by 6.3% in normoxia and 6.4% in hypoxia compared to no music.
Why the study?
Hypoxia exposure causes physiological and psychological impairment, and whether music could mitigate hypoxia-induced performance decrements was unknown.

Does self-selected motivational music improve physical performance in normoxia and hypoxia in young healthy males?
p-value: p=0.001
Self-selected motivational music enhances upper-body physical performance and voluntary muscle activation in both normoxic and hypoxic conditions.
May enhance exercise tolerance in hypoxia; hypothesis-generating for clinical populations before practice adoption.
Humans exposed to hypoxia are susceptible to physiological and psychological impairment. Music has ergogenic effects through enhancing psychological factors such as mood, emotion, and cognition. This study aimed to investigate music as a tool for mitigating the performance decrements observed in hypoxia. Thirteen males (mean ± SD; 24 ± 4 years) completed one familiarization session and four experimental trials; (1) normoxia (sea level, 0.209 FiO 2 ) and no music; (2) normoxia (0.209 FiO 2 ) with music; (3) normobaric hypoxia (∼3800 m, 0.13 FiO 2 ) and no music; and (4) normobaric hypoxia (0.13 FiO 2 ) with music. Experimental trials were completed at 21°C with 50% relative humidity. Music was self-selected prior to the familiarization session. Each experimental trial included a 15-min time trial on an arm bike, followed by a 60-s isometric maximal voluntary contraction (MVC) of the biceps brachii. Supramaximal nerve stimulation quantified central and peripheral fatigue with voluntary activation (VA%) calculated using the doublet interpolation method. Average power output (W) was reduced with a main effect of hypoxia ( p = 0.02) and significantly increased with a main effect of music ( p = 0.001). When combined the interaction was additive ( p = 0.87). Average MVC force (N) was reduced in hypoxia ( p = 0.03) but VA% of the biceps brachii was increased with music ( p = 0.02). Music reduced subjective scores of mental effort, breathing discomfort, and arm discomfort in hypoxia ( p < 0.001). Music increased maximal physical exertion through enhancing neural drive and diminishing detrimental mental processes, enhancing performance in normoxia (6.3%) and hypoxia (6.4%).
