- Effects of Exercise on..
- The Muscular System
- Long Term Effects
- Increased strength of muscles
- Increased muscle hypertrophy
- Increased myoglobin stores
- The tendons and ligaments also become stronger
- Short Term Effects
- Increase in muscle temperature
- Increased demand for oxygen
- Increased production of carbon dioxide
- Increased lactic acid production
- Muscle Fatigue
- Long Term Effects
- The Cardiovascular System
- Short Term Effects
- Increase in heart rate
- Increase in stroke volume
- Increase in systolic blood pressure
- Increased oxygen delivery and increased removal of carbon dioxide
- Increased rate of blood flow and therefore increased oxygen delivery
- Long Term Effects
- Increase in size and strength of the heart (cardiac hypertrophy)
- Increase in stroke volume
- Increased maximum cardiac output during exercise
- Good for fitness as the heart can contract more forcefully
- faster return to resting heart rate
- Lower resting heart rate
- Increased capillarisation
- Increased number of red blood cells
- Key Terms
- Heart rate = the number if times the heart beats per minute
- Stroke volume = the amount of blood leaving the heart each beat
- Systolic Blood Pressure = the pressure when blood is being pumped out of the heart
- Short Term Effects
- The Respiratory System
- Short Term Effects
- Increase in breathing rate
- Increase in depth of breathing
- Increase in removal of carbon dioxide
- increase in the amount of oxygen taken into the lungs in each breath
- Long Term Effects
- Increased number of alveoli
- Increased strength of intercostal muscles
- Increased strength of the diaphragm
- Increased lung volume
- Key Terms
- Total lung capacity = the total volume of air in your lungs after your biggest breathe in
- Tidal Volume = during normal breathing, the total amount breathed in and out in one cycle
- Vital capacity = the maximum you can forcibly breathe in and out
- Short Term Effects
- The Skeletal System
- Short Term Effects
- N/A
- Long Term Effects
- Increased bone density/ stronger bones
- Stronger ligaments and tendons
- Short Term Effects
- The Muscular System
