Study Notes
- Isometric exercise involves increasing tension in a muscle while keeping its length constant.
- It is also known as static exercise.
- Isometric contraction does not produce work.
- The muscle contracts without visible change in joint motion or muscle length.
- There is great tension and force output produced by the muscle.
- Compression of intramuscular arteries and veins prevents muscle vasodilation and increases blood flow.
- Rapid accumulation of lactic acid occurs due to decreased oxygen delivery.
- Muscle chemoreceptors are stimulated, which elevates the baroreceptor set point and sympathetic drive.
- Mean blood pressure is higher compared to dynamic exercise.
- Systolic and diastolic blood pressure increase.
