1. Which energy system predominates during a 6-second
maximal sprint?
A. Oxidative
B. Glycolytic
C. Phosphagen (ATP-PC)
D. Beta oxidation
Answer: C
Rationale: Efforts under ~10 seconds rely almost entirely on
stored ATP and phosphocreatine.
2. During eccentric contraction, the muscle:

B. Lengthens under tension
C. Relaxes completely
D. Produces no force
Answer: B
Rationale: Eccentric actions involve controlled lengthening
while resisting load.
