Most nutritional supplements do not enhance endurance athletic performance. Further research is needed for caffeine and phosphates, but losing excess body fat may improve endurance.

Area of Science:

  • Sports Science
  • Human Physiology
  • Nutritional Science

Background:

  • Athletic success in endurance events depends on genetics, training, and nutrition.
  • Endurance athletes use ergogenics to gain a competitive edge.
  • Many ergogenic aids have been investigated for their performance-enhancing effects.

Purpose of the Study:

  • To evaluate the efficacy of various nutritional ergogenics for enhancing endurance performance.
  • To identify nutritional practices and substances that may improve energy utilization and delay fatigue.
  • To determine the need for further research on specific ergogenic aids.

Main Methods:

  • Review of scientific literature on nutritional ergogenics and endurance performance.
  • Analysis of studies examining the effects of substances like caffeine, L-carnitine, and phosphates.

  • Consideration of nutritional practices such as body fat reduction.

    • Main Results:

    • Most nutritional ergogenics, including bee pollen, L-carnitine, CoQ10, inosine, amino acids, alkaline salts, and vitamin E at sea level, have shown ineffectiveness.
    • Research on caffeine, phosphate salts, and vitamin E at altitude yields equivocal findings.
    • Loss of excess body fat may be an effective ergogenic practice, while alcohol can impair performance.

    Conclusions:

    • Many commonly used nutritional ergogenics lack proven efficacy for enhancing endurance performance.
    • Further research is warranted for substances like caffeine, phosphates, and specific amino acids.
    • Future studies should utilize exercise protocols that mimic real-world endurance event demands.
