Key result
Nicotine gum chewed for 30 minutes enhanced motor reaction times, cognitive function, and baseball-hitting performance compared with placebo in healthy male baseball players (p < 0.05).
Why the study?
Evidence regarding the acute effect of nicotine on physical response and sports performance in baseball players remained scant.
Does nicotine gum improve physiological responses and sport performance in healthy male non-smoker baseball players?
Comparison
Nicotine gum chewed for 30 min vs flavor-matched placebo gum

Does nicotine gum improve physiological responses and sport performance in healthy male non-smoker baseball players?
Effect estimate: d = 0.47, 0.46 and 0.41
p-value: p=< 0.05
Nicotine gum chewed before exercise acutely enhanced cognitive function and baseball-hitting performance in healthy non-smoker baseball players, alongside changes in endocrine and sympathetic nerve activity.
Fang et al. (2022) conducted an RCT in Healthy baseball players (n=13). Nicotine gum vs. Flavor-matched placebo gum was evaluated on Physiological responses, cognitive function, muscle strength, and baseball-hitting performance (d = 0.47, 0.46 and 0.41, p=< 0.05). Nicotine gum chewed for 30 minutes enhanced motor reaction times, cognitive function, and baseball-hitting performance compared with placebo in healthy male baseball players (p < 0.05).
