This study set out to investigate if caffeine ingestion impacted anaerobic performance in upper-body exercise. The aim of the study was to see if time to exhaustion (TE) was increased with the ingestion of caffeine (3.5 mg.kg-1) during a constant load test at an intensity of 80 % of final minute power output (Wpeak; W) on an arm crank ergometer (ACE). It was hypothesized that caffeine ingestion would not influence TE, V02, VC02, VE and differentiated ratings of perceived exertion (RPE) during the constant load test trials. Seven upper-body trained athletes (mean ± s, age: 20.2 ± 0.7 yrs, weight: 80.7 ± 12.4 kg and height: 178 ± 7.9 cm) completed a graded exercise test (GXT) to calculate 80% Wpeak on the first visit. In the final three visits the participants competed a familiarization session at 80% Wpeak followed by the ingestion of caffeine or placebo in a randomized order. A 2-way ANOVA was performed on TE, V02, VC02, VE and RPE scores with no significant difference (P>0.05) observed between caffeine and placebo trials. These results suggest that anaerobic performance in upper-body dominant sports cannot be impacted by the ingestion of caffeine, the fact that there was no significant difference (P>0.05) observed between the physiological variables and RPE suggest that caffeine does not promote glycogen sparing or adenosine antagonism.

Holloway, Daniel (University of Wales Institute Cardiff, 2012)The purpose of this study was to determine the effects of caffeine on upper body muscular endurance performance. Well-trained university sports students (n=10, 20.3 ± 1.0 years, 84.0 ± 13.8 kg and 177.5 ± 4.4 cm) participated ...
Is coffee an effective pre-workout drink? – The effects of ingesting naturalistic doses of caffeine on one-repetition maximum muscular strength and muscular endurance in females. Thomas, Gabrielle (Cardiff Metropolitan University, 2015)Extensive research has been conducted on the ergogenic effects of caffeine for endurance performance yet far fewer studies have investigated the effects for intense, short-term exercise. Particularly lacking in documented ...
To explore the intake, knowledge and perceived perceptions of caffeine consumption on performance within a population of elite hockey players McClements, Jane (2018-04-01)Background: Previous literature has debated the effectiveness of caffeine as a stimulant on specific aspects of an athlete’s performance. Although associations have been drawn between caffeine consumption and performance ...
