Immediate & Short Term Effects of Exercise (AQA GCSE Physical Education): Revision Notes

Immediate & Short Term Effects Of Exercise

✍️ Immediate Effects Of Exercise:

• Getting Hot: Heat is a byproduct of energy production, the harder we train the hotter we get
• Getting Sweaty: Sweat glands produce sweat to cool you down, sweat evaporating from the surface of your skin removes some body heat
• Having Red Skin: Blood vessels dilate close to the surface of the skin to help you lose heat, this makes you look red
• Increased Depth and Rate of Breathing: This allows more gaseous exchange to occur more quickly. More oxygen can be delivered to the working muscles and more carbon dioxide can be removed
• Increased Heart Rate: This allows gases to be transported around the body. Oxygen can be delivered to the working muscles and carbon dioxide can be removed

✍️ Short-term Effects of Exercise:

• Tiredness and Fatigue: When we are exercising energy, stores are being used up which will lead to tiredness and fatigue

Short-term Exercise Effects

• Lightheadedness or Nausea: When we exercise, we lose fluids, which can lead to dehydration, Light headedness and nausea are symptoms of being dehydrated
• Aching Muscles: Blood vessels dilate close to the surface of the skin to help you lose heat, this makes you look red
• Cramp**:** A cramp is an involuntary muscular contraction. A cause of cramps is a depletion of energy stores or dehydration and a lack of electrolytes due to sweating
• DOMS**:** DOMS can occur due to micro tears in the muscles from vigorous activity
