BHK Trivia 5 — Questions and Answers
Question 1: Which phenomenon describes the temporary increase in strength following a period of detraining after heavy resistance training?
- Residual training effect
- Supercompensation (Correct answer)
- Post-activation potentiation
- Repeated bout effect
Correct answer: Supercompensation
Supercompensation theory predicts that fitness rises above baseline after a training stimulus and recovery period before returning to normal.
Question 2: What is the name of the proprioceptive organ found within muscle tendons that inhibits excessive muscle tension?
- Golgi tendon organ (Correct answer)
- Muscle spindle
- Pacinian corpuscle
- Ruffini ending
Correct answer: Golgi tendon organ
The Golgi tendon organ (GTO) detects tension in tendons and triggers autogenic inhibition to protect muscles from excessive force.
Question 3: Which metabolic byproduct was historically (but incorrectly) blamed for causing delayed onset muscle soreness (DOMS)?
- Lactic acid (Correct answer)
- Ammonia
- Reactive oxygen species
- Prostaglandins
Correct answer: Lactic acid
Lactic acid was long thought to cause DOMS, but research shows it clears within an hour of exercise; DOMS is now attributed to microtrauma and inflammation.
Question 4: What is the approximate energy yield (ATP) from the complete aerobic oxidation of one glucose molecule?
- 30-32 ATP (Correct answer)
- 2 ATP
- 4 ATP
- 8 ATP
Correct answer: 30-32 ATP
Complete aerobic oxidation of one glucose molecule via glycolysis, Krebs cycle, and oxidative phosphorylation yields approximately 30-32 ATP.
Question 5: Which Canadian sport scientist developed the General Adaptation Syndrome (GAS) model that underpins modern periodization?
- Hans Selye (Correct answer)
- Tudor Bompa
- Yuri Verkhoshansky
- Vladimir Zatsiorsky
Correct answer: Hans Selye
Hans Selye, a Hungarian-Canadian endocrinologist, developed the GAS model describing the body's response to stress: alarm, resistance, and exhaustion.
Question 6: What term describes the involuntary, rhythmic tremor of a limb caused by rapid successive stretching of a muscle, often tested at the ankle?
- Clonus (Correct answer)
- Fasciculation
- Myoclonus
- Tremor
Correct answer: Clonus
Clonus is a series of rhythmic muscle contractions triggered by sudden sustained stretch, indicating upper motor neuron lesion when pathological.
Question 7: The 'Copenhagen adductor exercise' is specifically used to strengthen which muscle group to reduce injury risk?
- Hip adductors (Correct answer)
- Hip abductors
- Hamstrings
- Quadriceps
Correct answer: Hip adductors
The Copenhagen adductor exercise is a Nordic-style loaded exercise targeting the hip adductors and has strong evidence for reducing groin injuries in athletes.
