With an increased use of liquid magnesium carbonate during the covid-19 pandemic because of its hand sanitizing properties we sought out to identify the muscular endurance benefits of dry and liquid magnesium carbonate during a pinch grip on a wood block. We hypothesized the application of dry and liquid magnesium carbonate will provide greater muscular endurance benefits than no magnesium carbonate during a submaximal pinch grip pull of 70 to 80% of maximum effort. Additionally, that liquid magnesium carbonate will provide similar benefits as dry magnesium carbonate. Five participants performed one trial of each of the three variables of dry hands with no magnesium carbonate, dry hands with dry magnesium carbonate and dry hands with liquid magnesium carbonate. Trials consisted of participant performing an isometric mid-thigh pull using a pronated pinch grip on a wood block. Dry magnesium carbonate grip increased by 177.7% as the largest and statistically significant change in grip duration. Whereas liquid magnesium grip duration increased by 108.8% compared to no magnesium carbonate however the change was not statistically significant. We recommend the use of dry magnesium carbonate during sport specific situations that require pinch grips on wooden surfaces, as it provided the greatest muscular endurance benefits. Additionally, encourage further research to be done on liquid and dry magnesium carbonate to provide definitive results, to be able to develop best practice of magnesium carbonate within the sport of rock climbing.
