Effects of Caffeine on Upper Extremity Performance

Not Applicable

Completed

• Conditions: Caffeine; Sportive Performance
• Interventions: Dietary Supplement: Caffeine Supplement

• Registration Number: NCT05916352
• Lead Sponsor: Cyprus International University

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).

Arm && Interventions

Group	Intervention	Description
Placebo Group	Caffeine Supplement	Placebo will be given
Caffeine Group	Caffeine Supplement	5 mg/kg caffein supplement will be given

Primary Outcome Measures

Name	Time	Method
Blood Lactate Level	2 hours	Lactic acid level in the blood

Secondary Outcome Measures

Name	Time	Method
Fatigue	1 minute	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".
Reaction Time	5 minutes	Arm movement speed
Anaerobic Power	5 minutes	Upper extremity explosive force will be measured with medicine ball
Muscular Endurance	5 minutes	Endurance time will be measured using a 1 kg Dynamometer.
