Effects of Caffeine on Upper Extremity Performance

The Effect of Caffeine Supplementation on Blood Lactate Level, Performance and Post-Training Fatigue in Elite Basketball Players

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.

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).

Inclusion Criteria:

• Elite basketball players aged 19-44
• Individuals with caffeine consumption below 2 mg per kg per day

Exclusion Criteria:

• Individuals with systemic disease affecting the musculoskeletal system
• Individuals using supplements containing caffeine
