Which type of stretching involves moving a joint through its full range of motion using controlled, active movement rather than holding a static position?
Answer: Dynamic stretching
Dynamic stretching uses controlled, sport-specific movements to increase range of motion and prepare the neuromuscular system for activity.
Which component of the nervous system controls involuntary functions like heart rate and digestion during exercise recovery?
Answer: Autonomic nervous system
The autonomic nervous system, via its sympathetic and parasympathetic branches, regulates heart rate, blood pressure, and digestion automatically.
During maximal exercise, which muscles receive the greatest increase in blood flow?
Answer: Active skeletal muscles
Blood is redistributed away from non-essential organs toward active skeletal muscles to deliver oxygen and nutrients and remove metabolic waste.
What does the 'lactate threshold' represent in exercise physiology?
Answer: The exercise intensity at which lactic acid production equals clearance rate
The lactate threshold is the intensity where lactate production begins to exceed clearance, causing blood lactate to accumulate rapidly.
A group fitness class progresses from bodyweight squats to weighted squats over 8 weeks. This is an example of which training principle?
Answer: Progressive overload
Progressive overload means gradually increasing training stress (load, volume, or intensity) over time to continue eliciting adaptation.
Which of the following BEST describes 'muscular endurance'?
Answer: The ability of a muscle to repeatedly exert force or sustain contractions over time
Muscular endurance is the capacity of a muscle or muscle group to perform repeated contractions against resistance without fatiguing.
Which plane of motion divides the body into front and back halves?
Answer: Frontal (coronal) plane
The frontal (coronal) plane divides the body into anterior and posterior sections; movements like lateral raises and side shuffles occur in this plane.
