AFAA-GFI CERTIFICATION EXAMINATION TEST
2026 QUESTIONS WITH SOLUTIONS GRADED
A+
● central nervous system - includes brain & spinal cord, coordinates
activity of body parts
● peripheral nervous system - includes all nerves branching from spinal
cord, extending out to the body
● mechanoreceptors - sense distortion in body tissues
● Golgi tendon organs - sensitive to changes in tension
● muscle spindles - sensitive to changes in length
● proprioception - cumulative sensory input to the CNS from all
mechanoreceptors
● tendons - connect muscle to bone
,● ligaments - connect bone to bone
● sarcomeres - individual contractile units; actin & myosin filaments
● type I muscle tissue - slow twitch, more aerobic, resistant to fatigue
● type II muscle tissue - fast twitch, more anaerobic, produce more
speed & strength; faster to fatigue
● behavioral properties of muscle - extensibility, elasticity, irritability,
ability to develop tension
● what is the isolated function (concentric action) of the quadriceps -
knee extension; ex. upward phase of a squat
● what is the isolated function (concentric action) of the hamstrings -
knee flexion; ex. hamstring curl
● what is the isolated function (concentric action) of the gastrocnemius -
plantar flexion; ex. calf raise
● what is the isolated function (concentric action) of the gluteus
maximus - hip extension & external rotation; ex. upward phase of lunge
, ● what is the isolated function (concentric action) of the rectus
abdominus - spinal flexion, lateral flexion & rotation; ex. ball crunch
● what is the isolated function (concentric action) of the pectoralis major
- shoulder flexion & horizontal adduction; ex. push up
● what is the isolated function (concentric action) of the latissimus dorsi
- shoulder extension, adduction & internal rotation; ex. band row
● what is the isolated function (concentric action) of the biceps - elbow
flexion; ex. bicep curl
● what is the isolated function (concentric action) of the triceps - elbow
extension; ex. triceps extension
● axial skeleton - skull, rib cage & vertebral column
● appendicular skeleton - bones of the upper & lower extremities
● what are the skeletal system function - movement, support, protection,
blood production, mineral storage
● non-synovial joint - no joint cavity or connective tissue; little to no
movement; ex. sutures of the skull
