International Journal of Sport Studies for Health 2588-5782 5 Serial Number 12 2022 09 01 The Immediate Effects of High Carbohydrate and Caffeinated Drinks on Speed, Coordination, and Cognitive Function in Professional Futsal Players The Immediate Effects of High Carbohydrate and Caffeinated Drinks on Speed, Coordination, and Cognitive Function in Professional Futsal Players 32 40 10.61838/kman.intjssh.5.1.5 EN Journal Article <article> <div class="mb content text-indent"> <h4 class="font-main d-inline font-weight-bold">Background:</h4> &nbsp;Researchers believe the beneficiary role of some supplements in improving futsal player's performance, since their performance is disturbed by lactate accumulation.</div> </article> <article> <div class="mb content text-indent"> <h4 class="font-main d-inline font-weight-bold">Objectives:</h4> &nbsp;In the present study, we aimed to investigate the acute effects of high-carbohydrate and high-caffeine drinks on the motor performance (speed and coordination) and cognitive function of futsal players.</div> </article> <article> <div class="mb content text-indent"> <h4 class="font-main d-inline font-weight-bold">Methods:</h4> &nbsp;The study utilized a quasi-experimental design with a pretest-posttest control group. The study involved 40 participants who were randomly assigned to one of four groups: (1) carbohydrate supplementation (N = 10), (2) caffeine supplementation (N = 10), (3) carbohydrate and caffeine supplementation (N = 10), and (4) control group (placebo). The subjects were given two different sports drinks, one containing carbohydrates and caffeine, each at a dose of 6 mL per kilogram of body weight, while the control group received a placebo. To measure speed, a 36-m sprint test was used, while coordination was assessed using a dribble and shoot test. Cognitive performance was measured using a modified version of the continuous performance test (CPT) developed specifically for use with futsal players.</div> </article> <article> <div class="mb content text-indent"> <h4 class="font-main d-inline font-weight-bold">Results:</h4> &nbsp;The study found that carbohydrate intake had a significant positive effect on reaction time and coordination (P &lt; 0.05). Caffeine intake was also associated with a significant improvement in cognitive performance (P &lt; 0.05), but no significant effect was observed on speed and coordination (P &gt; 0.05). Furthermore, the group that received both carbohydrate and caffeine supplements showed improvements in speed, coordination, and cognitive performance (P &lt; 0.05).</div> </article> <article> <div class="mb content text-indent"> <h4 class="font-main d-inline font-weight-bold">Conclusions:</h4> &nbsp;It is suggested that taking a supplement containing a combination of carbohydrates and caffeine for 5 days prior to performance may lead to improved results in speed and coordination tests.</div> </article> https://journals.kmanpub.com/index.php/Intjssh/article/download/2154/2581
