The Impact of MACA Supplementation on Basketball-related Performance

In this randomized crossover study, ten elite healthy male basketball players were included. Following a 17:00 PM training routine, participants completed a two-week supplementation with 2000 mg of MACA or placebo. After supplementation, participants underwent a Basketball Jump Shooting Accuracy Test and Repeated Sprint Ability Test.

About this study

Supplementation with Lepidium meyenii (MACA) has been shown in animal studies to increase blood lactate clearance and rapid lactate removal, which may be effective in reducing fatigue during intermittent exercise. However, no studies have investigated the effects of MACA supplementation on interval exercise and basketball performance. We hypothesized that MACA supplementation could reduce fatigue and improve performance in elite healthy male basketball players. This study aimed to determine the effectiveness of MACA compared to placebo on overall basketball performance.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • (i) healthy male adults, those individuals who are free of pain, insomnia, or other injuries recently, without any medication used in recent 2 months,
  • (ii) basketball players competing in a Taiwan university basketball association for more than two years.

Exclusion criteria

  • (i) were below 20 years old,
  • (ii) did not have won at least eighth place in national-level basketball competitions,
  • (iii) were with cardiovascular diseases or any disease that made subjects feel ill.

Treatment and study plan

Lepidium meyenii (MACA)

Dietary Supplement

The MACA supplement is derived from a concentrated 6:1 blend of black, red, and yellow MACA root compounds, with an 80:15:5 ratio respectively.

Other names: 100% corn-starch maltodextrin powder

Primary outcomes

  1. Countermovement jump test

    Time frame: immediately after 2 weeks intervention

    Three jumps were measured with 1 minute rest for each participant.

Secondary outcomes

  1. Basketball Jump Shooting Accuracy Test

    Time frame: immediately after 2 weeks intervention

    The first test was the basketball jump shooting Accuracy Test (BJSAT), which has been used in the past with sufficient reliability to two and three-point shooting accuracy

  2. Repeated Sprint Ability Test

    Time frame: immediately after 2 weeks intervention

    Repeated Sprint Ability test (40× 15m with a 1:4, exercise : rest time ratio, such as 2 seconds :8 seconds)
