Study Notes
Long-Term Effects of Exercise
- Exercise, depending on the type, can improve various fitness components.
- Anaerobic exercises, involving moving heavy objects, build muscle strength.
- Repeated exercises like sit-ups improve muscular endurance.
- Exercises improve joint stability and suppleness (flexibility).
- Aerobic exercises, like running or swimming, improve cardiovascular endurance and stamina.
Bradycardia
- Long-term training programs result in a higher heart rate.
- The heart muscle, like any other muscle, will increase in size through hypertrophy due to regular intense exercise.
- Increased heart size allows for greater force when contracting, and thus a bigger stroke volume.
- Resting heart rate reduces (bradycardia) in trained individuals to maintain the same cardiac output (Q = SV × HR), even though stroke volume (SV) increases.
Cardiac Output
- Cardiac output (Q) is calculated by multiplying stroke volume (SV) and heart rate (HR).
- Q=SV x HR
- If Q remains the same and SV increases, then heart rate (HR) must decrease.
