Question

The accommodating resistance is a feature of all given below except:

• A. Isokinetic exercise
• B. Constant velocity exercise
• C. Exercises with preset velocity of muscle shortening or lengthening
• D. Isotonic exercise
• E.

Hint:

Isotonic exercises have constant resistance, unlike isokinetic exercises where resistance adjusts to the muscle's force.

Answer 1

The Correct Option is D

Step 1: Understanding accommodating resistance.
Accommodating resistance refers to exercises where resistance varies based on the force exerted by the muscle. It ensures that muscles are constantly challenged throughout the range of motion. Isokinetic exercises are an example where this principle is applied.
Step 2: Analyzing the options.
- (1) Isokinetic exercise: Correct. These exercises use equipment that adjusts resistance according to the force exerted by the muscle.
- (2) Constant velocity exercise: Correct. This form of exercise maintains a constant speed, often utilizing accommodating resistance.
- (3) Exercises with preset velocity of muscle shortening or lengthening: Correct. These exercises follow a predetermined velocity, which can be adapted for varying resistance.
- (4) Isotonic exercise: Incorrect. Isotonic exercises involve constant resistance through the full range of motion and do not adjust according to muscle force.
Step 3: Conclusion.
Thus, the correct answer is (4) Isotonic exercise, as it does not feature accommodating resistance.
