b) Intercellular phosphate
c) Anaerobic glycolysis
d) Aerobic glycolysis
3. All three energy systems are used in all sports and should be trained and improved for
successful sport performance
True
4. The specificity of training principle means that exercise and training should be specific to the
type of strength and demands required for the athletic event
True
5. Students will recover faster from common viral illnesses (e.g., a cold) if they continue the same

9. The "Use it or lose it!" principle (reversibility) states that if training is stopped, a student's
strength, fitness and body composition will return to pre-training levels very quickly - within
two weeks
True
10. Based on the specificity and reversibility principle, training during the off-season should:
