Effects of Caffeine on Upper Extremity Performance

Study Overview
=================
Brief 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.

Detailed 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).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Blood Lactate Level | Lactic acid level in the blood | 2 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reaction Time | Arm movement speed | 5 minutes | 
| Anaerobic Power | Upper extremity explosive force will be measured with medicine ball | 5 minutes | 
| Muscular Endurance | Endurance time will be measured using a 1 kg Dynamometer. | 5 minutes | 
| 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 |
