Question

1. Which of the following is the normal variability in peak torque between right and left limbs in individuals with no previous or current injury, and not engaged in a unilateral sport, such as tennis?

Up to a 10-15% difference between limbs

Up to a 2% difference between limbs

Up to a 25-30% difference between limbs

Up to a 5% difference between limbs

2. What type of flow-volume loop would you expect in an individual with asthma who is experiencing bronchoconstriction?

Normal shape but lower maximal volume

Concave shape

Convex shape

Convex shape and lower maximal volume

3. Which of the following best describes the relationships between physical activity, physical fitness, and risk of premature mortality from all causes?

Increased physical activity reduces risk of premature mortality, but physical fitness does not affect risk of premature mortality.

Increased physical activity and/or increased physical fitness reduce risk of premature mortality.

Increased physical fitness reduces risk of premature mortality, but physical activity does not affect risk of premature mortality.

Neither physical activity nor physical fitness affect risk of premature mortality.

4. Which balance assessment would be most appropriate to assess fall risk for a healthy, 80 year-old individual who lives independently?

Y-balance test

None of the choices listed

Fullerton Advanced Balance Scale

Balance Error Scoring System (BESS)

Answer 1

Please find correct answer below

1. Which of the following is the normal variability in peak torque between right and left limbs in individuals with no previous or current injury, and not engaged in a unilateral sport, such as tennis?

Up to a 10-15% difference between limbs

Explanation: Inter limb asymmetry is common in normal people in standard the difference in normal variability in peak torque between right and left limb is almost 10-15% difference

2. What type of flow-volume loop would you expect in an individual with asthma who is experiencing bronchoconstriction?

Concave shape

Explanation: In broncho constrictive conditions like asthma the inspiratory flow and expletory flow is very less .So the volume flow loop take concave shape

3. Which of the following best describes the relationships between physical activity, physical fitness, and risk of premature mortality from all causes?

Increased physical activity reduces risk of premature mortality, but physical fitness does not affect risk of premature mortality.

Explanation: Physical activity is very important to reduce pre mature mortality rate according to studies but there is no significance of physical fitness in premature mortality risk .

4. Which balance assessment would be most appropriate to assess fall risk for a healthy, 80 year-old individual who lives independently?

Fullerton Advanced Balance Scale

Explanation: Fullerton advanced balance scale is balance test for active older adults to find out the risk of fall.
