Eric Oetter profiles repeated-sprint athletes and their energetic demands and tells how to optimally prep the proper energy systems with interval training
Changes in exercise responses (A, SpO2; B, heart rate; C, RPE). Mean ± SD (n = 13). The repeated-sprint exercise protocol included a first set of eight sprints
Exercise induces a multitude of physiological and biochemical changes in blood affecting its redox status. Tissue damage resulting from exercise induces activation of inflammatory cells followed by the increased activity of myeloperoxidase (MPO) in circulation. Vitamin C readily scavenges free radicals and may thereby prevent oxidative damage of important biological macromolecules. The aim of this study was to examine the effect of vitamin C supplementation on oxidative stress and neutrophil inflammatory response induced by acute and regular exercise. Experiment was conducted on acute exercise group (performing Bruce Treadmill Protocol (BTP)) and regular training group. Markers of lipid peroxidation, malondialdehyde (MDA), MPO activity, and vitamin C status were estimated at rest and after BTP (acute exercise group) and before and after vitamin C supplementation in both groups. Our results showed increased postexercise Asc in serum independently of vitamin supplementation. They also showed that vitamin

N2 - Purposes To assess the reliability, criterion and construct validity of multiple repeated-sprint sets test (RSS) in young soccer players. Methods To investigate the reliability and criterion validity of the RSS test, 24 young soccer players who belong to a professional team club took part in this study. They performed the RSS test twice, both vertical and horizontal jumps, the 20-m maximal shuttle run test and the yoyo intermittent recovery test. To examine the construct validity of the RSS test, we recruited 25 other young soccer players who belong to a regional team club to complete the RSS test. Results Reliability of total sprint time (TST) and best sprint time (BST) of the RSS test was very good, with intraclass ...

PubMed is a very large database with records for millions of articles. Its easy to get overwhelmed! A great way to start your research is to take advantage of PubMeds Medical Subject Headings (MeSH). Try using the MeSH terms for Beverages, Food, and Nutritional Physiological Phenomena. You can browse for MeSH terms in the MeSH database. When you find one that you want to use, click the button on the right that says "Add to search builder." When youre finished adding MeSH terms to your search, you can search PubMed using the "Search PubMed" button. Getting too many results? Try going back to MeSH and checking the box that says "Restrict to MeSH Major Topic." This will limit your search results to only the most relevant articles. Remember you can also use the filters on the left side of the PubMed results screen! Using the Article Type - Review filter is particularly helpful when youre starting your research ...
