Exercise therapy

Which of the following is a key component of PNF techniques?

• • Use of static stretching only

• • Alternating contraction and relaxation of muscles

• • Rapid, ballistic movements

• Continuous passive movement with no contraction

Which of the following best describes the hold-relax technique in PNF?

• • Stretching a muscle to its limit and holding it

• • Contracting the muscle against resistance before stretching

• • Performing a series of quick stretches

• Using a partner to assist in stretching

What does 1 RM measure?

• • The maximum weight a person can lift once with proper form

• • The maximum number of repetitions a person can perform

• • The endurance level of a muscle group

• • The flexibility of a muscle group

• 
  Testing at the end range of motion with muscle providing isometric contraction is called a

• • Break test.

• • Resistance check

• • Contractability test

• • Make test

Which of these would help improve the inter-rater reliability of MMT?

• • Using a consistent method and standardized positions

• • Allowing examiners to modify testing positions based on patient comfort

• • Limiting MMT use to grades 0 to 3 only

• • Performing MMT only on patients with low muscle strength

What is a limitation of BMI as a measure of body health?

• • It requires complex calculations

• • It doesn’t distinguish between muscle and fat

• limited generalizability

• not applicable for paediatric population

A waist-to-hip ratio (WHR) above which value is generally considered a health risk for men?

• • 0.50

• • 0.90

• • 1.0

• • 1.5

Waist-to-hip ratio (WHR) is often used over BMI to assess health risk because:

• • WHR provides more information on lean muscle mass

• • WHR specifically measures visceral fat distribution

• • WHR is easier to measure than BMI

• • gender specific

Which principle is fundamental to Progressive Resistance Exercise?

• • Reversibility

• • Overload

• • Continuity

• • Flexibility

When calculating training loads, if a person’s 1 RM for a squat is 200 kgs, what weight should they use to train at 80% intensity?

• 80 Kg

• 150 Kg

• 160 Kg

• 180 Kg
