Fat intake and high performane athletes
I promised a bit about feeding so here we go. I know feeding fat is all the rage in our horses. Yes it is good, to a point. For the super athletes though it is pointless. I am posting a abstract of a paper written about human endurance using increased fat intake.
Now before I hear anyone saying but these are humans, not horses, I have this to say. Our cells work on the same as a horse. Energy uptake is the same in them as it is us, as it is with other living creatures. It applies, and if you do not believe me go ask a Biology Prof ok.
When we, or our horses, preform as an athlete our muscles go for glucose immediately. If there is not enough available then our cells go for the fat. Good for losing weight, bad for athletes. It takes more energy and thus more time to break down fat. This also has a large impact on lactate build up after a work out. The moment my horses heart rate, breathing, and body temp is back to a normal range I give them a carb boost. Why? Because it stops the cannibalistic action of our body eating away muscle tissue to repair itself and turns it anabolic by using the carbs there for the taking. It does not take much. I personally use cracked corn and a digital scale with portions tailored to my work out for my barrel horses. They stay amazingly fit, happy and not sore. I will post more as time permits.

The effects of adaptation to a high-fat diet on endurance performance are equivocal, and there is little data regarding the effects on high-intensity exercise performance. This study examined the effects of a high-fat/moderate protein diet on submaximal, maximal, and supramaximal performance. Twenty non-highly trained men were assigned to either a high-fat/moderate-protein (HFMP; 61 % fat) diet (n = 12) or a control (C; 25% fat) group (n = 8). A maximal oxygen consumption test, two 30-s Wingate anaerobic tests, and a 45-min timed ride were performed before and after 6 weeks of diet and training. Body mass decreased significantly (-2.2 kg; p less than or equal to .05) in HFMP subjects. Maximal oxygen consumption significantly decreased in the HFMP group (3.5 +/- 0.14 to 3.27 +/- 0.09 L (.) min(-1)) but was unaffected when corrected for body mass. Perceived exertion was significantly higher during this test in the HFMP group. Main time effects indicated that peak and mean power decreased significantly during bout 1 of the Wingate sprints in the HFMP (-10 and -20%, respectively) group but not the C (-8 and -16%, respectively) group. Only peak power was lower during bout 1 in the HFMP group when corrected for body mass. Despite significantly reduced RER values in the HFMP group during the 45-min cycling bout, work output was significantly decreased (-18%). Adaptation to a 6-week HFMP diet in non-highly trained men resulted in increased fat oxidation during exercise and small decrements in peak power output and endurance performance. These deleterious effects on exercise performance may be accounted for in part by a reduction in body mass and/or increased ratings of perceived exertion.
