“…Multiple mechanisms might be responsible for reduce RPE in exercise. Caffeine increases the activation of the sympathetic central nervous system through adenosine receptor antagonism (Davis, Green, 2009) thus, caffeine is in blocking the inhibitory properties of endogenous adenosine (particularly at A 1 and A 2A receptors), resulting in increased behaviors related to dopamine, norepinephrine and glutamate release (Brunyé et al, 2010;Lorist, Tops, 2003). Adenosine inhibits the release of most excitatory neurotransmitters in the brain, particularly dopamine, and might reduce dopamine synthesis (Woolf, Bidwell, Carlson, 2008).…”

“…Adenosine inhibits the release of most excitatory neurotransmitters in the brain, particularly dopamine, and might reduce dopamine synthesis (Woolf, Bidwell, Carlson, 2008). Adenosine A1 receptors are present in almost all brain areas (The highest levels are found in the hippocampus, cerebral and cerebellar cortex, and certain thalamic nuclei) (Lorist, Tops, 2003), caffeine might inhibit adenosine from blocking neuronal transmission and thus alter perception of pain, alertness, wakefulness (Brunyé et al, 2010), sympathetic activity, motor recruitment, and fatigue (Woolf, Bidwell, Carlson, 2008). The results, caffeine might also increase time to exhaustion.…”

“…Moreover, to evaluate the explosive power of the lower body, vertical jump (Sargent) was performed. In addition, the RAST (Runningbased Anaerobic Sprint Test) test was performed after a 15-minute rest (Mora-Rodríguez et al, 2012), consisting of six repetitions at a distance of 35 m. And the maximum intensity is a quick run with 10 s rest between each repetition (recorded during the test by a timer 0.01 sec); it was calculated using the following formula:Peak anaerobic power = weight (kg) × 35 2 / repeated fastest time 3The participants filled out Borg RPE scale and pain perception after the tests (Brunyé et al, 2010;Cook et al, 1997;Cook et al, 1998). Pain perception was measured using a 0-10 categorical scale with ratio properties after 1RM leg press, 60% 1RM leg press, Sargent test, and RAST test (0=no pain at; 10=extremely intense pain (almost unbearable) (Cook et al, 1997;Cook et al, 1998).…”

“…The results, caffeine might also increase time to exhaustion. Because caffeine is a dopamine agonist increased dopamine release (Brunyé et al, 2010), it could possibly reduce RPE (Woolf, Bidwell, Carlson, 2008).In contrast, Astorino et al (2011b) and Astorino, Roupoli, Valdivieso (2012) not altering demonstrated RPE, pain perception, on influence ingested moderate dose (6 mg/ kg) and 2-5 mg/kg caffeine 1 h before cycling performance and high-intensity exercise on active women and men (Astorino, Roupoli, Valdivieso, 2012). Also, carbohydrate availability does not limit functions during exercise less than one hour as completed, so caffeine may not alter RPE during activities in which glycogen depletion does not occur (Astorino, Roupoli, Valdivieso, 2012).…”

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. Caffeine/ performance. Caffeine/pain perception. 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.,...

“…In addition to exercise, caffeine is suggested to have positive effects on multiple aspects of cognition including vigilance, mental alertness, reaction time, visual selective attention, task switching, conflict monitoring and response inhibition [6]- [8]. Caffeine is thought to cause these improvements by antagonizing adenosine receptors; it blocks the action of this inhibitory neurotransmitter by directly acting on both pre-and postsynaptic receptors [8].…”

Exercise has widely been shown to improve cognition, potentially by making individuals more receptive to sensory stimulation or inhibiting irrelevant information. Caffeine, one of the world's most widely used stimulants, seems to have similar effects. It seems that both exercise and caffeine improve cognitive function separately, but little research has been done examining their combined effects. The purpose of this study was to examine the impact of caffeine and exercise, independently and combined, on cognitive function. 20 healthy college students completed the study. These participants were low caffeine consumers. Each participant came to the lab 5 times. During the first session, they completed a graded exercise test on a cycle ergometer to determine ventilatory threshold (VT). The following four sessions were test sessions involving supplementation and exercise. During these, each participant engaged in 30 minutes of cycling (at 90% VT) or 30 minutes of quiet reading after consuming either caffeine (at 4 mg/kg body weight) or a placebo. The Contingent Continuous Performance Task (CPT) and Wisconsin Card Sorting Task were used to measure cognitive function and were completed 5 minutes and 20 minutes after exercise or quiet reading. There were no significant differences found for any variables tested, for condition effect, time effect or condition * time interaction, except for a significant time effect on false alarms on the Contingent CPT (p = 0.017). This study may have been limited by multiple variables including the population, executive function measures, caffeine dosage, or exercise prescription. These findings point to the need for future research to understand the changes in cognition from exercise and caffeine in combination. Future research may include looking at exercise at different intensities, different dosages of caffeine, or looking at the long-term cognitive effects.

In 2002, Fan and his colleagues developed the Attention Network Test (ANT), a cognitive tool that provides a score for each of the attentional networks (alerting, orienting, and executive functioning). Since publication, this study has been cited over 3 500 times. The authors state one of the indicated uses of this tool is to measure how different interventions, both behavioral and pharmacological, influence the networks of attention. The present review focuses on this premise and investigates how various aspects of lifestyle differently impact the networks of attention.Whether trying to optimize the attentional networks to improve cognitive performance, or to prevent the cognitive decline that occurs with age, this review summarizes what practices promote efficiency within the alerting, orienting, and executive functioning networks. The specific areas of lifestyle this review focuses on are meditation, exercise, drug use, sleep, and environmental or social factors.
