The Role Of Protein And Carbohydrate Utilisation During Exercise

The biological value in whey protein enhances the body’s ability to absorb essential amino acids after resistance training decreasing the athlete’s recovery time. When athletes combine whey protein and creatine monohydrate they expect “a greater increase in lean tissue mass and muscular strength than supplementations with whey protein alone” (Burke, Chilibeck, Davison, Candow, Farthing, & Smith-Palmer 2001, p 350). Exogenous Cr supplementation increases the body’s Cr levels until saturation occurs. This saturation of Cr increases the PCK shuttle continuum allowing training intensity, volume, and duration of the exercise the athlete is performing to continue at a maximum rate. Any excess Cr in the blood is cleared through sweat, urination or renal filtration. Measurements in strength and peak torques of athletes supplementing with whey protein and creatine monohydrate (WC), whey protein (W), and a placebo (P) were taken. According to Burke et al, (2001) “repeated measure analysis of variance was used to assess changes in body composition, strength, and peak torque for the three groups (WC vs. W vs. P) across time” (p. 354). A twelve week strength training program was constructed and consisted of a “4-day split routine involving whole body musculature” (Burke et al, 2001. p 352). Subjects used detailed training logs to compare progress over the 12 week experiment. The end result from this experiment shows that subjects who “supplemented with both creatine and whey

In contrast to athletes consuming recovery drinks for vital nutrients, studies have shown that food like fresh fruits and veggies are also great for replenishing athletes. Bananas, for example, contain necessary vitamins, minerals, nutrients, and electrolytes. This makes them an excellent post-workout snack. Furthermore, bananas are commonly known for having a large amount of potassium, which helps keep an athlete’s body healthier by protecting muscle mass (Michelle). In addition to having an abundance of potassium, bananas are an exceptional source of another crucial mineral: magnesium. Magnesium helps athletes recover by keeping their blood pressure levels regulated. This demonstrates that putting foods like bananas and other fruits and veggies

A double-blind study was performed, in order to determine whether health young men performing prolonged resistance-typed exercise training would have increased muscle mass and strength when protein supplements were consumed before sleeping. Forty-one health young men participated in a supervised progressive resistance-typed exercise training, which were performed three times a week for a total of twelve weeks. In addition, the participants were required to consume a bottle consisting of either a protein or noncaloric placebo drink prior to sleeping on a daily basis. To prevent any bias in the results, the bottled beverages were masked for taste, smell and color and distributed randomly to each participant. The impact of the study was assessed based on the before and after measurements of body composition, muscle fiber type composition, muscle

Presented in the Nutrition and Athletic Performance background article are relevant disclaimers on dietary supplements and ergogenic aids, meaning performance enhancers, directed towards athletes. As stated, many sports bars and drinks contain risky ingredients; that is why reading food labels and appropriate ingestion of these products is important. Carbohydrates, often referred to as carbs, are used to make glucose. Glucose is responsible for fueling your body and the energy can be stored. Extra energy storage is found in the glycogen. As Caitlin Campbell and her coauthors discuss in my designated article, conducted studies demonstrate that by drinking carbohydrates, exercise performance is enhanced because of the glucose levels in the blood and the extra storage of glycogen. Sports drinks, bars and gels are forms of carbohydrate-supplements designed to enhance performance for high training athletes. Do carbohydrate supplements, ingested by high endurance athletes, make a difference in their fuel uses and cycling time-trial performance?

β-alanine (BA) is a popular ergogenic aid within sport and exercise performance, largely due to its ability to increase intramuscular carnosine concentrations. Carnosine (β-ALANYL-L-HISTIDINE) is a histidine containing dipeptide, found in high concentrations in skeletal muscle (1, 20) and also within the CNS (25), and is synthesised by the joining of histidine and BA in a reaction catalysed by carnosine synthase (27). It is widely acknowledged that BA availability is the rate limiting factor in the synthesis of carnosine (16, 27), and as such, chronic dietary supplementation (4-10 weeks) with BA has been shown to significantly increase muscle carnosine concentrations (15, 17) with an increase of ~80% reported with an average does

Muscle protein synthesis is a common term used in the lifting world. Often people do not actually understand what this actually is. Muscle protein synthesis is a natural process that our bodies go through after any type of work the muscles do to repair, grow, and become stronger. While weightlifting, muscles are breaking down, becoming damaged and our bodies repairs itself through muscle protein synthesis. After leaving the gym and eat protein the body takes the protein and moves it into the cells to repair it. This window will last between 36-48 hours until the muscle is rebuilt and recover, experienced lifters will have a shorter duration (Leal). As long as loads are stressing the body it will respond with muscle protein synthesis.

Awareness to nutritional importance of best post-workout meal for lean muscle is imperative. Pushing yourself too much to heavy gym exercises may damage your muscles especially when not supported by proper and best post-workout meal for lean muscle. High intensity trainings and exercises depletes your energy stores such as carbohydrates, proteins and others nutrients. That is why you need to have adequate and proper nutrition before and after workouts. Here are best post-workout foods to guide you in your physical fitness goals.

It is stored in the brain, heart, as well as muscles, and can help an individual train for extended periods of time, all while reducing fat. L-carnitine is very effective at boosting muscle growth, as it takes the fatty acids from whole food and converts it into energy for the body.

The ketogenic diet has been trending among scientists and athletes as a method of improving physical performance and decreasing body weight. A ketogenic diet consists of high fat (>60% of energy) and low carbohydrate (<10% of energy) diet with adequate protein. This diet can induce a metabolic condition called “ketosis,” which increases levels of circulating blood ketone bodies (1). Many competitive athletes in endurance sports maintain a ketogenic diet with the concept that a low carbohydrate-high fat diet will increase the rate of free fatty acid metabolism during exercise, while preserving muscle glycogen stores for later use during the most demanding part of the exercise. One key difference between fat and glycogen metabolism is that more ATP can be generated rapidly from carbohydrate than fat oxidation. Glycogen breakdown yields 1.0-2.0 mol ATP/min while free fatty acid oxidation yields only 0.40 mol ATP/min. Several studies

Oxidation of these amino acids occurs in skeletal muscles. Though BCAAs are not used as a source of energy in the body under normal conditions, they do contribute to energy generation during heavy and strenuous exercise. The subsequent breakdown of these amino acids for energy generation during heavy exercise leads to muscle damage and tear. Therefore, restoring them with the help of protein supplements is extremely necessary to make up for the loss of proteins.

Purpose: This test is to investigate the effect of water and glucose solution, during moderate intensity exercise on post-exercise appetite. Methods: A male participate (Age: 24yr; BMI: 20.5kg/m2; VO2max: 57.7ml/kg/min) completed one preliminary VO2max test first. After that, complete two main trials separately with different solution. Participant had to cycling at 55% VO2max for 30 minutes and resting 30 minutes. During the whole experimental period, participant consumed total three times solution at the beginning, 15th minutes and 30th minutes of the test. Moreover, body weight, blood sample and appetite test scores were collected in different period of time. Results: During and after the exercise, the blood glucose of G trial is higher

do not in themselves enhance muscle growth in all individuals who are following their usual diet and exercise habits. The decline in insulin that occurs during prolonged exercise further increases this challenge. These data emphasize the importance of the

In order to build a muscle up, it gets torn down on a microscopic level. After every workout the muscle tearing process causing your body to rebuild them, thus, creating a larger muscle. To increase the recovery time, it is important to take nutritional supplements such as “Whey Protein,” amino acids, and glutamine. “Whey Protein” is a form of protein which is needed to fuel the muscles in order for the muscles to grow larger. Amino acids and glutamine help by replenishing your muscles of glucose, and giving them a boost of energy. If you did not replenish your body with these supplements, your body would start to take protein and other amino acids from your muscles causing them to lose size and strength, thus, defeating the purpose of working out to gain muscle mass.

Eat carbohydrates and protein, either in food or supplement form, before, during, and after an exercise session. Consuming a protein supplement powder prior to lifting weights or resistance training helps build muscles (protein synthesis) and may limit muscle damage during exercise. Eating a protein supplement powder within three hours after exercise can maximize muscle protein synthesis.

After exercise, your body needs fuel to start the recovery process and replenish muscle and liver glycogen stores. This is the best time to eat protein and simple carbs. Protein is made up of amino acids, which are the building blocks of muscle. You also need up to 30 grams of simple carbs to restore glycogen stores.
