HES 410-lecture 5 Metabolic Responses and
Adaptations Exam Questions and Answers
with Verified Solutions | Latest Updated 2026



ATP-PC system -short term 0-15 secs
-high energy
-anaerobic


glycogen system -anaerobic
-moderately high intensity
-1-2 min
-high levels of LA


oxidative system -aerobic
-long sustained energy needs


body only stores enough ATP for 1-2 seconds



law of mass action chemical reactions taking place in
solutions
progress to the right with the addition of
reactants
or progress to the left with the addition of
products
until equilibrium

, metabolic adaptions -increase substrate storage at rest
-altered enzyme activity
-limited accumulation of meabolities
-buffer capacity


ATP (myosin ATPase)-> ADP +Pi + energy



ADP +creatine phosphate ATP+ creatine
(creatine
kinase)->


ATP-PC resynthesis rates 50% within 20 seconds
75% within 40 seconds
87% within 1 min


nearly all ATP is restored within 3 mins



All ATP is restored in 8 mins



Rt training adaptions ATP and CP [ATP] and [CP] increase
can store more substrate


sprint training adaptions little effects



depletion/repletion training -supercompensation effect
adaption -ability to store more substrate over time


CK ATPase and training increase with hypertrophy, less than power
training
