Name the four ways muscle strength can be measured and briefly describe each.

Answer:

The four ways muscle strength can be measured are: 1. 1-Repetition Maximum (1RM): Measures the maximum amount of weight a person can lift for one repetition of an exercise. 2. Dynamometer: A device used to measure the force of a muscle contraction, commonly used to test grip strength. 3. Calisthenics: Exercises that use body weight as resistance (such as push-ups or sit-ups) to evaluate strength and endurance. 4. Computer-assisted or Isokinetic machines: Specialized equipment that measures the force exerted by a muscle through a full range of motion at a constant speed.
