Part4: Amphetamines

Comprises a group of pharmacological compounds that exert powerful stimulating effects on the central nervous system. They have a sympathomimetic effect leading to increase in heart rate, blood pressure. breathing rate and blood glucose.

Athletes use it to "get up" for the event and to psyche themselves up. The IOC bans the use of the substance though research indicate that they do not enhance performance.

Part4: Amino Acids

An emerging trend involves using nutrition as a "legal" alternative to activate the body's normal anabolic mechanisms. Weight lifters, bodybuilders and health freaks regularly use amino acid supplements, believing they boost the body's natural production of testosterone, GH, insulin, or insulin-like growth factor I (IGF-1) and so improve muscle size and strength and decrease body fat. The rationale for this stems from the clinical use of amino acid infusion or ingestion to regulate anabolic hormones in deficient patients.

However, research on healthy subjects does not provide convincing evidence for an ergogenic effect of regular intake of amino acid supplements on hormone secretion, training responsiveness, or exercise performance.

Stimulating and anabolic effect

Manipulation and timing of intake of nutritional variables in the immediate pre- and post- exercise periods can affect the responsiveness to resistance training via mechanisms that alter the nutrient availability, enzyme activity, and hormonal secretions, interactions with receptors on target tissues, and gene translations and transcription.

Resistance training stimulates protein synthesis and protein degradation in exercised muscle fibers. Muscle hypertrophy should occur when there is a net increase in protein synthesis. Dietary modifications that increase amino acid transport into muscles and that which also increases anabolic hormones like insulin should on paper increase anabolism and/or depress catabolism.

Carbohydrate-Protein Supplementation in Recovery Augments Hormonal Response to Resistance Exercise

Studies show that there is a transcient 4-fold increase in protein synthesis following a carbohydrate-protein supplement consumed prior or immediately after resistance exercise. Other studies show enhanced glycogen and protein synthesis with increasing carbohydrate and protein intake following a workout.

Postexercise Glucose Augments Protein balance after resistance training

A study showed that glucose post resistance exercise reduced muscle catabolism and increase leucine incorporation into muscles.

I have been busy traveling so have been slack in writing on this blog and my gospel writing blog.
