When free fatty acid is high hexokinase commits glucose to glycolysis

Phosphofructokinase is the rate limiting enzyme in beta oxidation

Increases in free fatty acid leads to increases in glycolysis

Increases in citrate inhibits the production of pyruvate

There is no significant relationship between hand grip strength and EMG signals, as EMG primarily measures muscle electrical activity unrelated to strength.

As hand grip strength increases, EMG signal amplitude decreases due to reduced muscle fatigue.

EMG signal amplitude remains constant regardless of changes in hand grip strength, as muscle activation patterns do not vary with strength.

EMG signal amplitude increases linearly with hand grip strength, reflecting higher motor unit recruitment and muscle activation.
