“…The results showed that consumption of 5 mg/kg caffeine compared with placebo reduced RPE and perceptions of pain after muscular endurance test, which is in agreement with a range of preceding studies (Backhouse et al, 2011;Doherty, Smith, 2005;Duncan et al, 2013) and is contrast to studies reporting no significant reductions of RPE and perceptions of pain after tests following acute caffeine ingestion (Astorino et al, 2011b;Astorino, Roupoli, Valdivieso, 2012).…”

“…Also, Duncan et al (2013) and Backhouse et al (2011) demonstrated that moderate dose (6 mg/kg) of caffeine ingested 1 h prior to exercise was associated with a maintenance effect in relation to feelings of pleasure and lowered perceptions of effort and RPE reduction. The study of Duncan et al (2013) showed that RPE was significantly lower during upper body exercises compared to lower body exercises. Also, muscle pain perception was lower in the caffeine condition, irrespective of exercise.…”

“…In a review article, Doherty and Smith (2005) reviewed 21 studies and revealed moderate to high caffeine doses (4-10 mg/kg) ingested 30-90 min before exercises reduced RPE obtained during submaximal aerobic exercise versus placebo. Also, Duncan et al (2013) and Backhouse et al (2011) demonstrated that moderate dose (6 mg/kg) of caffeine ingested 1 h prior to exercise was associated with a maintenance effect in relation to feelings of pleasure and lowered perceptions of effort and RPE reduction.

The present study set to examine the effects of different doses of caffeine on performance, rating of perceived exertion (RPE), and pain perception in female teenager athletes of karate. Ten female karate athletes (16.8±1.23 years; height 1.59±0.28 m; body-mass 57.73±8.33 kg; BMI 22.71±3.05 kg/m 2 ) participated in the study. A double-blind, randomized, and crossover counterbalanced design was used. In three sessions (with an interval of seven days'), ten female karate athletes ingested low dose (2 mg/ kg), moderate dose (5 mg/kg) caffeine, and placebo. Sixty minutes after consumption, they performed the tests as below: one repetition maximum and 60% of one repetition maximum in the leg press, explosive power test, and anaerobic RAST test. After the tests, the participants' RPE (6-20 scale) and pain perception (0-10 scale) were recorded using various categorical scales. The results showed that caffeine ingestion at moderate dose significantly reduced RPE and pain perception values compared with the placebo during muscular endurance test (P=0.0001 and P=0.039, respectively). The findings suggest that caffeine dose of 5 mg/kg body mass appears to improve RPE and pain perception in female teenager athletes of karate. The dose of 2 mg/kg body mass does not confer any additional improvement in performance.Uniterms: Caffeine/effects. Karate athletes/performance. Caffeine/rating of perceived exertion.

INTRODUCTIONCaffeine (1,3,7-trimethylxanthine) is a plant alkaloid that occurs naturally in the diet (Sökmen et al., 2008) and nearly 90% of US adults consume caffeine in forms of coffee, tea, or other caffeinated food products (8 cup of coffee may contain 50-200 mg caffeine) (Owens, 2015;Yang, Palmer, De Wit, 2010). In the U.S.A., adults ingest an average of 3 mg/kg of caffeine daily in coffee, tea, caffeinated sodas, and many other drinks and food (Sökmen et al., 2008). The popularity of caffeine as an ergogenic aide has increased dramatically over the last decade (Hendrix et al., 2010), Caffeine is the most widely consumed to improve cognitive, physical performance during exercise and has become a popular ergogenic aid among recreational and competitive athletes (Hendrix et al., 2010;Sökmen et al., 2008;Zheng et al., 2014).Caffeine is classified as part of the methylxanthine family of drugs (Cechella et al., 2014;Mohr, Nielsen, Bangsbo, 2011) and is extensively consumed by athletes as an ergogenic aid (Backhouse et al., 2011;Mohr, Nielsen, Bangsbo, 2011) since its removal from the World AntiDoping Agency (WADA) prohibited list of substances (Backhouse et al., 2011;Mohr, Nielsen, Bangsbo, 2011). According to the Medical Council of International Olympic Committee (IOC), caffeine is allowed in sports as long as its urinary excretion level is below 12 µg/mL (Bell, Jacobs, Ellerington, 2001).Taken orally, caffeine reaches a peak plasma concentration of 30-90 min after ingestion, and a halflife has been reported to be 3 to 5 hours with a modest intake of coffee (Sökmen et al.,...

“…However, the impact of caffeine upon short duration high intensity activity remains unclear; with some studies showing no effect or even a performance decrement with caffeine supplementation [61][62][63]. Duncan et al however, reported that number of repetitions completed was higher when caffeine was ingested 60 min pre-RE [64]. This suggests that total work was higher in the caffeine condition.…”

Resistance Exercise (RE) is a widely practiced activity both in leisure time and in training periods for competitive athletes. Recent advanced in molecular biology and muscle physiology has elucidated some of the mechanisms that regulate muscle growth. As a result of these biochemical advances, an increased number of supplements claiming to enhance adaptations to Resistance exercise have become available. Essentially, the aim of these supplements is to influence protein synthesis and therefore gradual protein accretion leading to increased muscle size and strength. The aim of this review is to discuss the most commonly consumed supplements associated with RE and make recommendations with regards to timing, volume and combinations of supplementations.

Caffeine Supplementation as an Ergogenic Aid for Muscular Strength and Endurance: A Recommendation for Coaches and Athletes

Caffeine (1, 3, 7-trimethylxanthine) which can be ubiquitously found in energy drinks, sodas, coffee, and supplements, is one of the principal legal drugs consumed worldwide. Caffeine based ergogenic aids are utilized prolifically within training and competition for an ergogenic benefit to enhance sporting performance by both recreational and elite athletes. The evidence of caffeine's ability to enhance endurance performance is well established, however, evidence of an ergogenic benefit for muscular endurance and strength-based tasks is limited. Moreover, the limited evidence for caffeine's ergogenic benefit in muscular endurance and strength is equivocal, and therefore, practical recommendations for the implementation of caffeine supplementation in training and competition for coaches, and practitioners is difficult. Indeed, it is currently not known if, and how caffeine may improve muscular endurance and/or strength based tasks. Variability in the findings could be due to several factors including muscles tested, participant characteristics, exercise protocol, type and dose of caffeine used. This brief review will discuss the current literature relating to the potential efficacy of caffeine to enhance muscular endurance and strength based performance, and provides evidence based recommendations for athletes and coaches to implement. Caffeine's primary mechanistic process likely occurs through the antagonising of adenosine [27]. This process is achieved by caffeine binding to adenosine receptors, reducing adenosine's ability to slow neural activity, reduce arousal, and induce sleep [28]. Further rewards from caffeine's effect on adenosine receptors include enhanced neurotransmitter release, increased firing rates, and amplified spontaneous and evoked potentials [29]. Caffeine has also been shown to alter metabolic substrate utilization [9] and provide enhanced fat oxidation and consequential glycogen sparing [30]. Alterations to pain perception following caffeine supplementation have also been reported [31] most likely due to enhanced secretion of β-endorphins [32]. More specifically to strength performance, possible mechanisms also include increased muscle activation [33], motor unit recruitment [34], and enhanced excitation contraction coupling [35]. KeywordsIt should be noted, that it is beyond the scope of this review to provide a comprehensive overview of the mechanisms of caffeine. The primary purpose of this review is to provide in depth analysis of the evidence relating to the use of caffeine in muscular endurance and strength based exercise, and provide coaches and athletes, at both elite and recreational level, with recommendations for the use of caffeine with regards to muscular strength and muscular endurance. For a complementary, wider-ranged review of all current literature, readers is direct to other published review articles [36,37] and a meta-analysis [38].
