  1. CONTRIBUTION OF SCIENCE TO IMPROVE SPORTING PERFORMANCE How does science improve sports capabilities ? PROU Léa & TAGEDDINE Inès

  2. Biological (physical) factors different performance factors Technical factors (strategic) Psychological factors Social factors Factor of luck

  3. Some Sciences allow to develop these notions such as : The physiology The anatomy Biochemistry

  4. The great discoveries that have emerged from this research are : • Structure and muscular functioning • energetic metabolism of the muscle • the nervous control of the movement • hormonal regulation during the exercise • energy expenditure, nutrients used during the exertion • the cardiorespiratory system and its Control

  5. Muscle The structure of skeletal muscle The physiology of the muscle

  6. • The different energy regeneration pathways: The muscle cell has three regeneration pathways : The aerobic pathway (presence of oxygen), pathway of cellular respiration. (ex: 5000m) The anaerobic (no oxygen) pathway, lactic fermentation pathway. (ex 400m) The anaerobic (in absence of oxygen) alactique route , pathway of phosphocreatine, pathway of immediate regeneration. (ex: 100m)

  7. Different types of muscle fibers: There are three types of muscle fibers: Type I Type IIa Type IIb

  8. The food pyramid

  9. food supplements

  10. • Adaptation of the body during aerobic training (in the presence of oxygen) use of circulating fatty acids (preferential substrate) adaptation of the cardiovascular function to the effort (decreased resting heart rate and resting blood pressure) Increase of maximum oxygen volume (VO2max) increase in muscular blood flow (better intakes of oxygenated blood to the muscle) Increase in the share of type I fibres delayed lactic threshold (best stress tolerance)
