About this study

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
  • Individuals with any diagnosed neurological or orthopedic disease

Treatment and study plan

Caffeine Supplement

Dietary Supplement

Caffeine tablet

Primary outcomes

  1. Blood Lactate Level

    Time frame: 2 hours

    Lactic acid level in the blood

Secondary outcomes

  1. Reaction Time

    Time frame: 5 minutes

    Arm movement speed

  2. Anaerobic Power

    Time frame: 5 minutes

    Upper extremity explosive force will be measured with medicine ball

  3. Muscular Endurance

    Time frame: 5 minutes

    Endurance time will be measured using a 1 kg Dynamometer.

  4. Fatigue

    Time frame: 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".
