Caffeine and Sprint Cycling Performance: Effects of Torque Factor and Sprint Duration

Abstract

The results of this study show that when torque factor and sprint duration are optimized, to allow participants to express their highest PPO, there is a clear effect of caffeine on sprinting performance.

Una Semana de Consumo de Café con Cafeína en Dosis Bajas o Moderadas No Induce Tolerancia a los Efectos Precisos de la Cafeína en el Rendimiento del Sprint

“…However, acute CAF ingestion significantly increased LA values at the post-test compared to PLA but this difference was not apparent after consumption of 1 week placebo, 3 or 6 mg/kg of CAF One of two main findings of current study is FIRSTCAF significantly improved sprint performance prior to 1 week of consumption period. Although anhydrous form of CAF was shown to be ergogenic on sprint performance by numerous studies (Dominguez et al, 2021;Glaister et al, 2019;Mohr et al, 2011), current study is first to found 6 mg/kg caffeinated coffee enhanced sprint performance compared to decaffeinated coffee as a placebo. Due to the methodological difficulties, coffee could not compared with anhydrous form but it is known that both coffee and anhydrous form improves resistance (Richardson et al, 2016) and endurance (Hodgson et al, 2013) exercise performance.…”

“…Of these, caffeine (CAF) is most commonly administered prior to and during a game (Tallis et al, 2021). The acute intake of CAF doses of 3-6 mg/kg of body mass has been well established to improve performance in various exercise modalities including aerobic (Southward et al, 2018), anaerobic activities (Davis and Green, 2009), muscle performance such as strength (Grgic et al, 2020), muscular endurance (Flip-Stachnik et al, 2021), maximum power (Dominguez et al, 2021) and intermittent sprint performance (Mohr et al, 2011;Glaister et al, 2019). On the other hand, it has been still reported to be ineffective on some performance parameters (Clarke et al, 2016;Trexler et al, 2016).…”

Gender differences in postural balance, physical activity level, BMI, and body composition in athletes with visual impairment

“…Athletes visited the laboratory at least ±2 hr post-prandial. They were instructed to report to each test session in well-hydrated state, not to exercise the day before the test trials and to abstain from the caffeine intake for 3 hr prior to each test (Glaister et al, 2015(Glaister et al, , 2019Greer et al, 1998;Grgic, 2018). Muscle fatigue and vigorous PA may affect balance control; therefore, balance test did not take place after training and athletes who were engaged in vigorous PA excluded from the study (Barbieri et al, 2013).…”

Sprint Cycling

“…PPO usually occurs a few seconds after a sprint is initiated (de Jong et al, 2015; Glaister et al, 2019; Wittekind et al, 2011), with power output declining thereafter. The optimal sprinting strategy has, therefore, been described as using an all-out approach (Abbiss & Laursen, 2008).…”

“…There is, however, evidence to suggest that pacing does still exist during single (de Jong et al, 2015; Glaister et al, 2019; Wittekind et al, 2011) and repeated sprints (Billaut et al, 2011). During single sprints, even though the time to PPO was unaltered, a lower PPO has been found when longer sprints were undertaken (de Jong et al, 2015; Glaister et al, 2019; Wittekind et al, 2011). During repeated sprints, in comparison to a controlled trial, where the participants were correctly informed that they would be required to perform ten 6 s sprints with 24 s of recovery, power output was significantly higher during the first sprint, as well as the cumulated work over the first five sprints, in the deception trial, where the participants believed that they were only going to perform five sprints (Billaut et al, 2011).…”
