Clinical Trial Summary

It was aimed to apply caffeine supplement to elite basketball players and to investigate the effects of this supplement on upper extremity performance, lactic acid level and fatigue. The investigators also aimed to investigate the effects of blood lactate level on performance and fatigue.

Description:

The aim of this study is to examine the effects of caffeine supplementation on upper extremity performance, lactic acid and fatigue in elite basketball players and compare them with the placebo group. A total of 50 elite basketball players, 25 each in the caffeine and placebo groups, will participate in the study. Caffeine supplement will be given 1 hour before the measurements (5mg/kg). Muscular endurance before and after reinforcement, scapular muscular endurance test (SKET); arm movement speed, disc touch test (DDT); anaerobic power, medicine ball throwing (STF); lactic acid (LA) level will be evaluated by finger blood measurement and fatigue visual analog scale (VAS).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blood Lactate Level	Lactic acid level in the blood	2 hours
Secondary	Reaction Time	Arm movement speed	5 minutes
Secondary	Anaerobic Power	Upper extremity explosive force will be measured with medicine ball	5 minutes
Secondary	Muscular Endurance	Endurance time will be measured using a 1 kg Dynamometer.	5 minutes
Secondary	Fatigue	Subjective fatigue will be measured using the Visual Analog Scale which ranging from 0 to 10 points. A value of 0 describes "no pain" and a value of 10 describes the "most pain".	1 minute
