Short-term

• • Where changes happen up to 36 hours after exercise, this is considered a short-term effect of exercise
• Tiredness/Fatigue

  The muscles have been working hard and become swollen and feel heavy which can lead to tiredness. This sensation can also be caused by muscles using up stores of carbohydrates during respiration and the energy supply is reduced
• Light-headedness

  This can also present as feeling dizzy; this is often due to low blood sugar or low blood pressure
• Nausea

  If the participant has overexerted themselves during exercise this can leave them feeling nauseous as blood is directed away from the stomach and digestive organs to the heart and lungs
• DOMS

  Occurs because of small tears in the muscle that happens during exercise that cause swelling and soreness in the muscles
• Cramps

  Caused by involuntary contractions of muscle that happen because of fatigue; dehydration and loss of minerals can contribute to cramps (not the same as DOMS)
