Therefore, endurance athletes need to ensure high levels of protein intake not only to supply amino
acids for growth, but also to make sure that the amino acids don't get burnt
up as fuel.Endurance athletes need proteins but do they need protein supplements? The answer, till
recently, was negative for recreational and modest athletes. They start at a low key, setting
a steady rhythm and culminate into a crescendo that enthralls the spectator and the athlete.
If any of these prerequisites are not met, the internal milieu becomes uncomfortable. With enough
proteins, the lean body mass, stamina and performance increase throughout the training program.Proteins and amino
acids also directly supply between 1 to 6 % of the energy needs during a
workout. Metabolism slows down, to allow excretion of wastes, acids and heat, as fatigue sets
in. Protica manufactures capsulized foods, including Profect, a compact, hypoallergenic, ready-to-drink protein beverage containing zero
carbohydrates and zero fat. The aerobic stress of endurance sports provides the necessary stimulus for
growth and development. You can also learn about Profect at http://www.profect.com.References1. Just eating proteins in
diet does not ensure that they will provide all the essential amino acids in adequate
quantities. Greater the intensity of the workout, greater is the efficiency required. Measurements based on
nitrogen balance do not take the accommodative state into account and are therefore are not
accurate chaussures puma enough to calculate protein requirements. However, when the protein intake is inadequate, the high-energy
diet fails to protect proteins from being used up as fuel. Effect of oral glucose
on leucine turnover in human subjects at rest and during exercise at two levels of
dietary protein.J Physiol 2000525(pt 1):2714. The capacity of the cardiovascular and respiratory systems, the fuel
stores in the muscle, the hepatic and renal support systems must all expand exponentially to
perform in endurance sports. Given the vital role that proteins play in the metabolic and
physiological response to aerobic stresses of endurance sports, and the uncertainties regarding dietary protein intake,
a protein supplement like Profect®, can go a long way in improving performance.Adequate training and
a Profect diet will take endurance to its limits, to levels where aerobic metabolism stimulates
the release of enkephalins, the human equivalent of opium. Endurance Sports are like music concerts.
McKenzie S, Phillips SM, Carter SL, Lowther S, Gibala MJ, Tarnopolsky MA:Endurance exercise training attenuates
leucine oxidation and BCOAD activation during exercise in humans. As each system, conducted by the
human will, endures a pace bordering on fatigue, the athlete begins to hear music from
the heart. Am J Physiol Endocrinol Metab 2000278:E5803.Bowtell JL, Leese GP, Smith K, et al.
As long as metabolism remains aerobic, the mind is flooded with enkephalins and the systems
function in Tn Requin harmony. The body is ready to build. These enkephalins produce the natural high
that is often referred to as the 'flow'. All that is needed are the building
blocks-the Proteins.Given an adequate and appropriate supply of proteins, the body remains in a state
of positive nitrogen balance. Given their role in bodybuilding, proteins are too important to be
used as fuel and attempts should be made to minimize this percentage. Protein supplements were
advised only for professional athletes and for sportspersons with a diet deficient in proteins. Information
on Protica is available at http://www.protica.com. Young VR, Bier DM, Pellett PL. A theoretical basis
for increasing current estimates of the amino acid requirements in adult man, with experimental support.
And not unlike an orchestra, endurance demands a flawless performance from every organ, testing the
limits of their resilience. Tarnopolsky M.:Protein Requirements for Endurance Athletes Nutrition 200420:662- 668.2. In 'flow'
capacity seems endless and fatigue non-existent. The proportion of energy derived from proteins increases with
the intensity of the exercise. Sufficient protein consumption, along with a high-energy diet also influences
the carbohydrate and fat metabolism. Mark Tarnopolsky, in a recent review on Protein Requirements in
Endurance Athletes, also raises similar questions.Epidemiological studies, by McKenzie and others, also suggest that the
dietary protein intake of up to 20% of athletes may be below levels recommended for
sedentary individuals. Studies by Bowtell and Tarnopolsky, report that a high-energy (carbohydrate) diet, when combined
with an ample protein intake and hydration, has a protein sparing effect under aerobic conditions.
What's often neglected, and considered unnecessary, in endurance sports is a high-protein diet that can
expand the aerobic capacity and power the performance.To sustain effort and delay fatigue, the body
needs an adequate supply of oxygen and fuel without accumulating waste products, acids or heat.
The consequent increase in muscle stores of glycogen and lipid allows sustained activity for a
longer time. Profect, the perfect protein supplement can do that for you.About ProticaFounded in 2001,
Protica, Inc. However, these recommendations, based on a parameter called 'nitrogen balance', have often been
questioned. Young and Bier propose that there exists a subtle state of protein deficiency, called
the 'accommodative' state, where an inadequate protein intake is masked by the breakdown of body
proteins. Then there is always the ambiguous quality and absorbability of a dietary protein. In
the well-fed state, with sufficient physical activity, dietary proteins stimulate the simultaneous release of the
growth hormone and insulin. The combined hormonal influence redirects dietary carbohydrate and fat to the
aerobic muscle fibers where they are stored as fuels for exhausting workouts. is a nutritional
