HSC Core 2: Factors affecting Performance

* Q. How does training affect performance?

Energy Systems

* the body requires energy for: muscular contractions
Glandular functions
Digestion
Blood circulation
Tissue building and repair

The body receives energy from food which is broken down into carbohydrates, fats and proteins

The ATP System :

Energy: Adenosine triphosphate (ATP) Enough One explosive movement

Release of energy: free phosphate (there are 3 phosphates) molecule and Adenosine diphosphate (ADP)
Regain of energy: resynthesis of APT molecules

| Alacticacid (ATP/PC):( Anaerobic without O2) | Lactic Acid:( Anaerobic without O2) | Aerobic: | Source of fuel | Creatine phosphate | Carbs in form of sugar | glucosefree fatty acids | Efficiency of ATP production | Very efficientQuick simpleDoesn’t rely on O2 | Continues to resynthesis APT after ATP/PC system has ceased | Endless supply for extended periods | Duration | 10-12 seconds | High intensity: 1-3 minsLow intensity: 3+ mins | 2-3 mins to few hours | Cause of fatigue | Inability of body to continually resynthesise | Blood lactate accumulation builds up on muscles | Depletion of glucosePoor circulation | By products of energy production | Heat | Pyruvis acid  lactate, H+ | CO2H2 | Rate of recovery | 2 mins to regain normal PC levels | 20 mins – 2hours to remover lactic acid from blood | O2 to reach muscles  2-4 minsHigher intensity longer time | e.g. of activities | 100m sprint, discus | 400m sprint | Marathon triathlon |
Types of training + training methods:

* 4 types: Aerobic
Anaerobic acronym - ( A . A. S. F)
Strength
Flexibility

Aerobic:

* Circuit: athletes completing different exercises or stations at a set interval of time with little or no rest.
-Effectiveness of circuit training relies heavily on how well the overload principle it applied, progressive
