The Effect of Carbohydrate Intake on Strength and Resistance
Muscle contractions during both low- and high-load resistance training rely primarily on the anaerobic glycolysis pathway for energy, as there is insufficient oxygen to rely purely on the aerobic system and fatty acids to provide energy sufficiently rapidly [4,5,6]. Hence, glycogen depletion could limit performance.

Tuned muscle and spring properties increase elastic energy storage
Alternatively, a spring that is relatively too stiff would result in very little muscle shortening and energy storage . Although our work suggests that a relatively stiffer spring maximizes energy storage, relatively compliant springs could be ideal in cases where the force capacity of the muscle is constrained (Rosario et al., 2016). Thus, to

6 FAQs about [Low muscle energy storage]
Are muscle glycogen stores critically low at fatigue and exhaustion?
Thus, a general observation is that muscle glycogen stores are not critically low at fatigue and exhaustion, i.e., <250–300 mmol. kg −1 dw, suggesting that exercise in the heat is terminated before available glycogen stores have been limiting.
