SBC Client Assessment and Screening 2 — Questions and Answers
Question 1: What does the term 'kinetic chain' mean in the context of a stability ball assessment?
- A chain of exercises performed in sequence
- The interdependence of all joints and muscles from feet to head affecting movement quality (Correct answer)
- A type of resistance band
- The speed of neural impulses
Correct answer: The interdependence of all joints and muscles from feet to head affecting movement quality
The kinetic chain describes the interconnected system of joints, muscles, and connective tissue from the foot to the head, where dysfunction at one segment affects others during stability ball movement.
Question 2: Which muscle is commonly identified as 'overactive' in clients with lower crossed syndrome affecting stability ball posture?
- Gluteus maximus
- Hip flexors (iliopsoas) (Correct answer)
- Tibialis anterior
- Lower trapezius
Correct answer: Hip flexors (iliopsoas)
In lower crossed syndrome, the hip flexors (iliopsoas and rectus femoris) are typically overactive and shortened, contributing to anterior pelvic tilt and poor stability ball posture.
Question 3: A client demonstrates 'knee valgus' during stability ball wall squats. This compensation most likely indicates weakness in which muscle?
- Tibialis posterior
- Gluteus medius (Correct answer)
- Biceps brachii
- Wrist extensors
Correct answer: Gluteus medius
Knee valgus (knees caving inward) during squat movements typically reflects weakness in the gluteus medius, which normally prevents inward collapse of the femur.
Question 4: Before using the stability ball with a client who has osteoporosis, the trainer must be most cautious about:
- The color of the ball
- Exercises involving spinal flexion under load and fall risk (Correct answer)
- The client's clothing
- Room temperature
Correct answer: Exercises involving spinal flexion under load and fall risk
Clients with osteoporosis are at elevated fracture risk; spinal flexion under load stresses vertebral bodies and fall risk from an unstable ball can lead to serious injury.
Question 5: Which movement screen finding suggests the client needs hip mobility work before stability ball glute bridges?
- Inability to achieve full hip extension lying flat (Correct answer)
- Strong grip strength
- High resting heart rate
- Excellent shoulder mobility
Correct answer: Inability to achieve full hip extension lying flat
Inability to achieve full hip extension indicates hip flexor tightness that will limit the range and effectiveness of stability ball glute bridges and cause lumbar compensation.
Question 6: An ideal initial fitness assessment for stability ball programming includes all of the following EXCEPT:
- Postural assessment
- PAR-Q completion
- 1-rep maximum barbell back squat (Correct answer)
- Overhead squat assessment
Correct answer: 1-rep maximum barbell back squat
A 1-rep max barbell back squat is not appropriate for initial stability ball assessment as it carries significant injury risk and is not relevant to establishing a stability ball baseline.
