Download or read book Food Components to Enhance Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1994-02-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Endurance athletes have long benefited from ingesting carbohydrates prior to, and during endurance events. Fatigue during endurance exercise has repeatedly been associated with the depletion, or reduction, of bodily carbohydrate reserves. The improved endurance capability observed after aerobic training has, however, been attributed to the increased oxidation of fat relative to carbohydrate, thereby having a 'carbohydrate sparing effect and thus delaying the point at which reduced carbohydrate reserves will cause fatigue. This study was therefore designed to investigate the effects of medium-chain triglyceride (MCT) and carbohydrate (CHO) supplementation, on the performance and metabolic parameters of nine male marathon athletes. These results were then statistically compared to the effects of adding L-carnitine to the MCT and CHO supplement, on the same parameters. Metabolic parameters included nutritional status evaluations, serum organic acid profiles (non-esterified fatty acid and L-lactate profiles), and plasma carnitine determinations. Performance was measured in terms of peak treadmill running speed, V02 max, respiratory exchange ratios, heart rates, vco2 and vo2 data during progressive treadmill exercise tests. Nutrition and energy intakes were recorded during the study, as well as record kept of the athlete's training programmes. At the end of each supplementation period, a standard marathon was included in the experimental design, in order to practically validate controlled laboratory results. The main findings of this study included the identification of two athletes as 'fat burners' ̃Non-esterified fatty acid (NEFA) profiles indicated that they predominantly relied on fatty acid oxidation during exercise, after MCT supplementation. The latter presumably because of adaptive changes in their metabolism, enabling them to benefit from MCT supplementation. In spite of the majority of athletes relying on carbohydrate metabolism during exercise, the addition of L-carnitine to the MCT and CHO supplement, induced a shift towards lipid metabolism: evident from RER and VC02 data, as well as the majority of athletes improving their performance. The observed shift was slight: the latter being ascribed to the relatively small dose of L-carnitine (compared to previous studies) included in the supplement. However, L-carnitine was incorporated into a palatable, liquid MCT and CHO supplement, and not merely administered in the form of a pharmacological dose. A major, and extremely unexpected finding, was the presumed effect that the winter, and continuous cold exposure, had on plasma carnitine levels. Plasma carnitine levels decreased significantly, without any intervention, prior to the start of the second trial period, which stretched over the middle of winter. Despite carnitine supplementation, plasma carnitine levels still decreased. This occurrence most certainly influenced results: the shift towards lipid metabolism would presumably have been more pronounced, had the 'Winter factor' not come into play.
Download or read book User s Guide to Carnitine and Acetyl L Carnitine written by Vera Tweed and published by Basic Health Publications, Inc.. This book was released on 2005-12 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: People who need more energy and want to avoid stimulants that will make them edgy should consider taking supplements of carnitine or acetyl-l-carnitine, two forms of the same nutrient found naturally in protein. Carnitine works by transporting fats in cells to where they are burned for energy. By boosting the activity of the body's cellular furnaces, carnitine can energize the heart, brain, and muscles to do more. Doctors have also found carnitine and acetyl-l-carnitine helpful in treating many conditions, including heart failure, muscle weakness and failing memory. Carnitine can also enhance physical training.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The study was designed to determine the effects of dietary L-carnitine supplementation on sprint performance and lactate/pyruvate (L/P) ratios following an aerobic bout of moderate intensity exercise. Elite male cyclists (N = 16) were examined (VO2max 71.8 6.1 ml.kg-1.min-1; age 29.0 7.3 yrs). Cyclists ingested either 2 g.day-1 of L-carnitine or a placebo for 28 days in a double-blind study. Blood L/P ratios were then analyzed pre and post 4 weeks of supplementation. Following the 4 weeks of supplementation, a 60-min ride at 80% of the lactate threshold of the individual cyclist was administered. During the 60-min ride respiratory exchange ratio (RER) and blood lactate measures were analyzed in 15-min intervals to estimate substrate utilization and lactate accumulation between treatments. Following the 60-min ride, a Wingate anaerobic test (WAT) was performed. Pre and post WAT L/P ratios were then analyzed. Statistical analysis revealed no significant treatment by time interactions with respect to lactate, pyruvate and L/P ratios pre and post 4 weeks of supplementation. Secondly, lactate, pyruvate, and L/P ratios before and following the WAT were not significantly different between groups. Moreover, no significant treatment by time interactions were present in RER and capillary blood lactate measures collected during the 60-min ride. Relative peak power scores obtained from the WAT were found to be significantly lower in the LC group as compared to the PL group (10.90 ł .72 watts/kg) and (11.90 ł .93 watts/kg) respectively. However, relative mean power and fatigue index measures were not found to be significantly different. In conclusion, L-carnitine supplementation does not alter lactate, pyruvate, and L/P ratios following 4 weeks of supplementation, 60 min of sub maximal cycling, and after a WAT. Furthermore, L-carnitine may not enhance sprint performance following an endurance event but may be ergolytic.

This book was released on 2013-04-22 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: We instinctively know that exercise, eating the right things, and taking vitamins sustains our health, maintains our youth, and offers a sense of wellbeing. Traditional fitness publications do a great job telling you what to do, but lack any explanation as to the why and how. They offer a map to youth by micromanaging your diet, exercise and or supplements. You blindly follow their lead in expectation of finding your fountain of youth through their training. Every body is different, which is why one map may work for one person, but not another; maybe it failed you, so you try another. What you may not realize is that although they offer step by step instruction to find the fountain, they are not teaching you how to read the map. Although the map is the same, the directions are different for each of us to find the fountain of youth. the difference between the layperson and expert is their ability to read the map as a whole; that map is our anatomy. That cartography lesson is learned by teaching you how exercise, diet and supplements work rather than being told what in the same to follow. At the end of the lesson, you may now understand that your journey may require parts of many methods, rather than the single direction of one. the author shares his own journey as he teaches you how to read the map, so you understand how one has successfully read the map to discover his fountain of youth.
