Research Papers that Mention the Interaction
“In conclusion, both the duration and magnitude of the ergogenic effect that followed a 5 mg/kg dose of caffeine were greater in the nonusers compared with the users.”
Exercise endurance 1, 3, and 6 h after caffeine ingestion in caffeine users and nonusers.“These data suggest that caffeine may play an ergogenic role in exercise performance by altering both neural perception of effort and substrate availability.”
“The main finding of this meta-analysis is that caffeine ingestion has a significant ergogenic effect on muscular endurance and muscular strength in women.”
“While discussing fruitful research areas to improve the knowledge about caffeine and performance [1], the authors highlighted a number of factors that potentially influence caffeine ’s ergogenic effect.”
“79 (57.7%) were associated with the use of caffeine with health variables, 52 (38.0%) were associated with the use of caffeine with ergogenic purposes , six (4.4%) were associated with regular caffeine intake.”
“However, there has been a long-standing paradigm that habitual caffeine intake may influence the ergogenicity of caffeine supplementation.”
“The coingestion of carbohydrate with caffeine has an ergogenic effect to reduce the sense of effort and increase high-intensity running capability that might be used to enhance interchange running performance in elite rugby league players.”
“No other statistical differences were found for the caffeine-placebo comparison for mean velocity, but caffeine induced an ergogenic effect of small magnitude in all of the menstrual cycle phases.”
“In comparison to the placebo, the ingestion of caffeine increased peak cycling power in the incremental exercise test by ~4.0 ±1.3% for the first 15 days (P<0.05) but then this ergogenic effect lessened.”
“These results show a continued ergogenic effect with the daily ingestion of caffeine for 15–18 days; however, the changes in the magnitude of this effect suggest progressive tolerance.”
“NEW & NOTEWORTHY There has been a long-standing paradigm that habitual caffeine intake may influence the ergogenicity of caffeine supplementation.”
