Abstract: Available evidence indicates that ketone bodies inhibit glycolysis in contracting muscles. Therefore, we investigated whether acute exogenous ketosis by oral ketone ester (KE) intake early in a simulated cycling race can induce transient glycogen sparing… read more here.

DOI: 10.1249/01.mss.0000517352.37238.50
Abstract: RESULTS: The trial returned low dropout rate (9%), high compliance and sensitivity (typical error 2.2%), but the effect of the multiple-transportable carbohydrate on overall performance time (-0.6%, 95%CI -1.8%, 0.7%), swim, bike, and run times,… read more here.

DOI: 10.14814/phy2.13555
Abstract: This study investigated the effect of carbohydrate (CHO) dose and composition on fuel selection during exercise, specifically exogenous and endogenous (liver and muscle) CHO oxidation. Ten trained males cycled in a double‐blind randomized order on… read more here.

DOI: 10.3390/nu14040862
Abstract: The introduction of the needle muscle biopsy technique in the 1960s allowed muscle tissue to be sampled from exercising humans for the first time. The finding that muscle glycogen content reached low levels at exhaustion… read more here.

DOI: 10.3390/nu15010155
Abstract: Muscle glycogen is a crucial energy source for exercise, and assessment of muscle glycogen storage contributes to the adequate manipulation of muscle glycogen levels in athletes before and after training and competition. Muscle biopsy is… read more here.
