The Effect Of Low-dose Caffeine Intake On The Overall Performance Of Basketball Players

Research Objective:In the current competitive arena,in order to obtain ideal sports performance,not only systematic training and nutritional recovery guarantees are required,but also non-training influencing factors to further improve the sports performance and cognitive function of athletes.Caffeine is an accessible sports supplement,and some studies have shown that caffeine can improve athletic performance and cognitive function in athletes with a certain training level,allowing athletes to show higher than usual performance in competitions.Competitive level.In the same-court competitive projects dominated by basketball-based skills,the overall performance of athletes is an important factor affecting the performance of the game.At present,the effect of low-dose caffeine on improving endurance sports has been determined,but the effect of low-dose caffeine on competitive sports dominated by skills such as football,rugby and basketball is still controversial,and whether it can improve specific skills and athletic performance has a positive effect is unclear.Therefore,the purpose of this study was to investigate the extent to which low-dose caffeine affects sports basketball specific sports skills and the effect of affecting sports cognitive function,hoping to help basketball,football,rugby and other athletes to further improve their game performance,and to propose a more scientific method.It has certain practical guiding significance to help athletes in competitive competitive sports on the same field improve their sports performance.Research methods:By recruiting 10 national second-level basketball players to conduct a randomized double-blind controlled experiment,taking 10 national second-level basketball players as the research objects,and taking basketball players’special ability as the research content,to explore the effect of low-dose caffeine on basketball players’ special The effect of ability,in the formal experiment,the subject athletes took a pre-test of cognitive performance(Stroop task),then took caffeine and a placebo,sat for 60 minutes,and then performed a second stroop test,followed by a basketball player-specific competition The ability test protocol includes(ball-holding sprint test,touch height test,one-minute shooting test on the basketball court)and then random intake of caffeine and placebo,namely placebo group(0 mg/kg,PLA),caffeine group 3 mg/kg body weight(3 mg/kg,CAF3),complete the Stroop task again after the special skill test and record it.The subject athletes completed a total of four formal experiments,with a 5-day interval between each experiment.All data were statistically analyzed using SPSS 23.0 statistical software.All measurement data are expressed as mean±standard deviation.Repeated measures were used to analyze the variation of each test data value.Post hoc analysis was performed with Bonferroni correction,and the level of statistical difference was set at P<0.05.Results:1.Ball-holding sprinting ability:Compared with the PLA placebo group,the CAF3 caffeine group has a lower average ball-holding sprinting time than the PLA group in terms of the ability to hold the ball and sprint(P<0.05)..2.Ability to touch heights:In terms of heights,the heights of vertical bounces with both feet in the CAF3 caffeine group were compared with the PLA placebo group.Higher than the PAL group,there was a very significant statistical difference in the improvement of the average touch height score(P<0.01),but there was no significant difference in the single-leg sprint touch height(P>0.05).3.Shooting ability:In the effect of caffeine on one-minute fixed-point shooting ability,the average number of shots in the CAF3 group was significantly different from that in the PLA placebo group,and the number of shots in the CAF3 group was higher than that in the PLA group(P<0.05),but the number of goals did not change significantly(P>0.05).4.RPE:In terms of average RPE,the CAF3 caffeine group was significantly different from the PLA placebo group in the RPE score after exercise compared with the PLA group(P<0.05).5.Consistent condition of Stroop task:The results of the study showed that in terms of reaction time,the CAF3 caffeine group had a significantly lower stroop reaction time after ingestion compared with the PLA placebo group,and there was a significant difference(P<0.05),but There was no significant change in the correct rate of ACC(P>0.05).6.Inconsistent requirements and standards of the Stroop task:The experimental results show that from the perspective of the athletes’ reaction time,the CAF3 caffeine group has a significantly lower reaction time after ingestion than the PLA placebo group(P<0.05).However,there was no significant change in the correct rate of ACC before and after ingestion(P>0.05),which was consistent with the results under the Stroop task-consistent condition.Analysis conclusion:This study found that,from the overall situation,low-dose caffeine intake in this experiment can improve the performance of basketball players in terms of physical fitness,including the ability to hold the ball and sprint,bounce,and reaction.At the same time,RPE subjective force perception The reduction of caffeine can also allow athletes to complete technical movements more easily,but in terms of shooting performance,although low-dose caffeine can improve the shooting speed to a certain extent,it does not help the shooting rate.
