What best describes the hormonal response during exercise that contributes to the breakdown of fat

If I took a drug that inhibited the increase in left ventricular wall thickness with aerobic exercise training, given that other structural adaptations to the heart are maintained, how would this affect wall tension and what would this change in wall tension mean

What best describes exercise fatigue

A person was performing a maximal lift with electrodes attached directly to the muscle.  The muscle force generated was less than what the person normally could generate. While that person was trying to generate maximal force, I directly stimulated the muscle fibers to contract via the electrode.  This direct stimulation DID NOT result in a further increase in the force generated above what was generated by the person alone.  What might this indicate about the state of fatigue?
