KIT AND EQUIPMENT
1. There are several factors that affect the selection of playing kit and equipment, the most obvious being environmental factors.
  1. climate – temperature, humidity and wind
    1. Temperature and UV exposure - resulting negative effect on endurance, speed and power.
    2. Humidity Conditions of high humidity affect how much sweat can evaporate and so transfer heat away from the body. The impact of this is a rise in the core temperature, with a resulting negative effect on physical performance.
    3. Wind - Wind can increase the rate of sweat evaporation, which can cause a direct cooling effect on the performer. Athletes will need to wear more clothing to counteract this – which could have a negative impact on performance.
  2. playing surface
  3. indoor or outdoor (also whether a stadium roof is closed or open)
    1. where air or fluid dynamics can influence performance, athletes may use clothing or other strategies specifically designed to reduce this effect.
  4. protection/reducing injury.
  5. Cultural factors may include the amount of support a performer or team receives from their home nation (or home club), particularly when competing in global competitions. Pressure from the media, and in some cases from governments and states, can affect performers as they prepare for competition.
2. Compression clothing
  1. benefits the manufacturers claim can be gained from wearing these compression garments include: • injury prevention • performance enhancement • speeding up of recovery.
    1. Studies found that wearing the clothing speeded up recovery, as it helped to increase blood flow to the areas covered and also had a positive impact on venous return.
    2. creates a constant pressure on the working muscles,
      1. increased blood flow helps feed the muscle with both oxygen and energy,
        speeds up the removal of waste products,
        reduces muscle vibration, which can reduce the possibility of delayed-onset muscle soreness.
  2. ICE VESTS AND THERMOREGULATION
    1. When body temperature rises, the blood is diverted away from the muscle to the skin in an attempt to cool down. This means less blood flows to the muscle, which has a negative effect on performance.
      1. vests allow athletes to perform for up to 19 per cent longer before temperature becomes a debilitating factor.
ACCLIMATISATION
1. It can take between five and ten days for a performer to acclimatise (respond and adapt) to changes in heat and humidity.
  1. As the body acclimatises, it becomes more efficient at thermoregulation. The sweat response starts earlier and works to a greater level. The body will begin to absorb more fluid from the performer’s diet, and their blood volume will also increase.
Key term - thermoregulation the ability to maintain body temperature within certain boundaries, even when the surrounding temperature is very different
