BHK Practice 4

Question 1

A kinesiologist uses a skinfold caliper assessment and applies the Jackson-Pollock 3-site formula. Which site combination is used for FEMALE clients in this protocol?

Accepted Answer

Triceps, suprailiac, thigh

Answer

The Jackson-Pollock 3-site formula for females uses the triceps, suprailiac, and thigh skinfold measurements.

Question 2

In the context of motor learning, a kinesiologist using blocked practice versus random practice would expect which long-term outcome?

Accepted Answer

Random practice produces superior retention and transfer of skills despite poorer initial acquisition

Answer

Random practice creates contextual interference that challenges the learner more during acquisition but results in superior long-term retention and transfer, known as the contextual interference effect.

Question 3

A kinesiologist is assessing a client's shoulder external rotation strength using a handheld dynamometer. To isolate the external rotators BEST, the client's arm should be positioned at:

Accepted Answer

90° shoulder abduction with the elbow flexed to 90°

Answer

With the shoulder at 90° abduction and elbow at 90° flexion, the infraspinatus and teres minor are optimally positioned and isolated for external rotation strength testing.

Question 4

Which energy system is the PREDOMINANT contributor to a 400-meter sprint in a trained athlete?

Accepted Answer

Anaerobic glycolysis (lactic acid system)

Answer

A 400-meter sprint lasting approximately 45–55 seconds is fueled primarily by anaerobic glycolysis, with contributions from both the ATP-PCr and aerobic systems.

Question 5

A kinesiologist working with a patient post-stroke notes decreased stride length and increased double-support time. These gait deviations are MOST indicative of:

Accepted Answer

A protective, cautious gait pattern reflecting reduced balance and strength

Answer

Reduced stride length and prolonged double-support time are compensatory strategies adopted by post-stroke patients to improve stability at the cost of efficiency.
