Excess post-exercise oxygen consumption (EPOC) is highest after which type of session?
Answer: High-intensity interval training
Higher exercise intensity creates greater metabolic disturbance and a larger EPOC.
What is the term for the point at which blood lactate begins to accumulate faster than it can be cleared?
Answer: Lactate threshold
The lactate threshold marks where lactate production exceeds clearance.
Which sensory receptor detects changes in muscle length and triggers the stretch reflex?
Answer: Muscle spindle
Muscle spindles sense rapid lengthening and trigger a reflexive contraction.
A client doing a squat has knees caving inward. Which muscle is most commonly underactive?
Answer: Gluteus medius
A weak gluteus medius fails to control hip adduction and internal rotation, causing knee valgus.
Which type of lever is most common in the human body?
Answer: Third-class lever
Most joints, like the elbow during flexion, act as third-class levers with effort between fulcrum and load.
Stroke volume multiplied by heart rate equals which value?
Answer: Cardiac output
Cardiac output is the volume of blood the heart pumps per minute.
Loss of training adaptations after stopping exercise reflects which principle?
Answer: Reversibility
Reversibility means fitness gains decline when training stops.
