Background: The aim of the present study was to investigate the effects of sodium bicarbonate supplementation on anaerobic performance and some plasma metabolites. Material/Methods: 16 young male athletes (age 20.58±3.25, Height 175.33±2.48 cm and BMI 21.57±2.68 kg/m2) participated in two 400 m running sessions one hour following sodium bicarbonate or placebo (calcium bicarbonate) supplementation with the counterbalanced order. There were three blood sampling phases (resting condition, 30 min after supplementation and 2 min after 400 m running) in both of the sessions and the blood pH; ammonia, lactate, and HCO3- levels were measured. Results: The results showed that running time …

Anaerobic Power And Hydration Status In Combat Sport Athletes During Body Mass Reduction, Anna Kurylas, Jakub Chycki, Tomasz Zajac
Baltic Journal of Health and Physical Activity
Background: Hydration is one of the most significant issues for combat sports as athletes often use water restriction for quick weight loss before competition. There is significant evidence to indicate that the hypohydration status impairs anaerobic performance. The aim of this study was to investigate if hypohydration, to reach a weight category, affects anaerobic performance. Material and methods: Six well trained combat sport athletes, classified in the middleweight division, took part in the experiment. The hydration status and anaerobic performance parameters were evaluated at four points in time (t1 – four weeks before fight, t2 – two weeks before fight, …
Ischemic Preconditioning Improves Maximal Accumulated Oxygen Deficit In Ncaa Division I Middle-Distance Runners, Emily Paull
Ischemic Preconditioning Improves Maximal Accumulated Oxygen Deficit In Ncaa Division I Middle-Distance Runners, Emily Paull
Electronic Theses and Dissertations
Purpose: There is an ongoing debate concerning whether ischemic preconditioning elicits consistent and meaningful exercise performance benefits. We have previously demonstrated no performance benefits of ischemic preconditioning at submaximal aerobic exercise intensities. It is likely that the beneficial effects of ischemic preconditioning on performance only involve supramaximal anaerobic exercise bouts, which elicit greater metabolic and neuromuscular stress. The aim of the study was to test the hypothesis that ischemic preconditioning improves maximal accumulated oxygen deficit (aO2D), an indicator of anaerobic capacity, in NCAA Division I middle-distance runners. Methods: A randomized sham-controlled crossover study was employed in which 10 NCAA Division …
