Effects Of Caffeine On Tennis Serve Accuracy, Benjamin Pj Poire, Lauren Killen, Matt Green, Eric O'Neal, Lee Renfroe
International Journal of Exercise Science
International Journal of Exercise Science 12(6): 1290-1301, 2019. This study examined the effects of caffeine on tennis serve accuracy. Division II tennis athletes (n = 10) completed two serve trials (double-blind, counterbalanced) following ingestion of 6 mg/kg of caffeine or matched placebo an hour prior to data collection. During each tennis serve trial, participants completed 48 non-fault serves divided into 3 sets with 2 serves per 8 different targets. Following each 2 serves per target format, participants completed a shuttle run sprint. Separate 2 (trial) x 8 (targets) repeated measures analysis of variances (ANOVAs) were used for distances from …

International Journal of Exercise Science
International Journal of Exercise Science 12(5): 646-656, 2019. This study assessed the effect of cell phone texting during a 30-minute bout of cycle ergometer exercise on measures of cognition (i.e., reaction time and accuracy). Twenty-eight college students participated in two conditions (cell phone and no cell phone). Reaction time and accuracy were assessed pre- and post-exercise with the use of the Stroop test. Reaction time was significantly worse (p < 0.001) in the cell phone condition from pre- (1003.75 ± 178.04 ms) to post-exercise (1124.46 ± 238.55 ms). Reaction time was significantly better (p < 0.001) in the no cell phone condition from pre- …
