One of the reasons that this lab was performed was to examine the effect that CHO had on prolonged exercise. In the high CHO experiment, the theory was that with an increased amount of CHO in the system would prevent the hepatic glycogen sparing. In the low CHO (high protein) diet, that the body could maintain the exercises breaking down the protein for energy. So the question that is asked is which diet provides the best source of energy for prolonged exercise. To start examining the differences of the two diets the caloric intake of the three days is necessary. In the high CHO diet, the average caloric intake of the macronutrients for the three days were: CHO 708 calories, Protein 205.5 calories, and Fats 146.7 calories. In the low CHO

The experiments variables agree with the theoretical expectation that a high CHO diet is better than a low CHO diet. The biggest supporter of the theoretical expectation is that the subject could not sustain the exercise for the full ninety minutes. In the high CHO experiment, the subject ran for the full ninety minutes at higher speed (5.55.8mph) and lasted longer on the TAT (50.69 seconds). While the low CHO experiment, the subject lasted seventy-five minutes at a slower speed (5.45.1 mph) and lasted 30.75 seconds. The first variable is blood glucose levels in both experiments. At the very beginning of the high CHO diet experiment the blood glucose was 107 mg/dL which is slightly higher than standard blood glucose. As the exercise started, the blood glucose decreased to 69.3 mg/dL which is the lowest it ever reached in the experiment. After that initial drop the blood glucose rose 72.1 mg/dL and it was maintained in the mid-seventies for the rest of the experiment. As for the low CHO, this was not the case. In the beginning, the blood glucose started at 69.1mg/dL which is bad because the standard level at rest is 80-100 mg/dL. At the very first measurement of blood glucose, the value actually increased to 73.1 mg/dL which is the highest it reached through the experiment until the TAT. So the question is: what is the difference between these two diets …show more content…
The next question that needs to be asked is what happens to protein after exercise. In the previous section, it was discussed that there is protein synthesis and protein breakdown and it is controlled by glycogen. In a review article Tipton and Wolfe (2001), explain there are three factors that play a role in protein synthesis: type of exercise performed, intensity, and condition. The goal of training is to get better so understanding the best way to stimulate protein synthesis is important. In resistance training, this is important because protein helps rebuild the
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
The purpose of this lab was to see if following the HHS (Health and Human Services) (Morgan P.11) suggested diet would be healthier or a person which follows their own diet. This was measured by the Fitness index. The results in average of the Fitness Index in Table 1.3 (P. 15) showed that the Athletic got a fitness index of 72.3 and the Sedentary got a Fitness Index of 70.6. In Table 1.1 (p.13) it shows that a high average is around 65 FI to 79 FI. The average are fairly close to each other which is shown in Table 1.6 (p.19) this is a bar graph of the averages. These results came from the different groups doing the following the same procedure. Some trends that were noted in the average was that many people got a higher index in sedentary
To build muscles, you need protein. To build muscles, you must maintain a sufficient amount of protein. Your body alone does not produce enough protein and that's why we need to find other sources, such as a high protein diet or a protein supplement, to provide the protein our body needs. Proteins will create body heat and speed up your metabolism. As a result, protein affects your metabolism which is more than fat or carbohydrates. This explains why the muscle mass is stronger than the fat. Exercise will change the metabolism of a person's protein. The amount of exercise a person does is fully understood by any protein provided by his
This activity was to record a detail food log, personal caloric needs and intake and comparing to a standard distribution. The standard distribution percentage given for this activity was 40% carbs, 30% proteins and 30%fats. In this analysis I will compare my personal results of caloric intake and estimate my BMR, TMR and how this impacts my weight management goals.
Carbohydrates are seen as our body’s primary source of quick energy. However, they provide another significant function to the individual. When ingested they can transform into glycogen that is later stored in the muscles and liver (Mayo Clinic, 2006). This glycogen in the muscles is the body’s fuel for training and competing and starts to deplete as you exercise at a high intensity (Heaner, 2004).
INTRODUCTION Breakdown of carbohydrates, proteins and fats produce ATP. An ATP demand is increased up to 1000- fold during high intensity exercise compared to that at rest (Spriet, 1992). ATP regeneration needs to meet the demands in order to sustain muscle contraction. To restock ATP in muscle, there are three energy systems function that take place inside body are 1) Mitochondrial Respiration, 2) Phosphagen and 3) Glycolytic system. These three systems vary in the usage of substrates, rate of ATP renewal, products and capacity of ATP renewal.
2.Replenish-Taking in carbohydrates to help in complete gain of the lost muscles glycogen and liver glycogen so that you are ready for the next training session.
The subjects refrained from caffeine, standardized diet, and standardized training for 48 hrs before the trials. For 24 hours before the trials, each subject was given a prepackaged standard diet. Exercise and food diaries were kept and checked for compliance.

We found that Joshua tended to eat a lot of protein. Chris ate a lot of protein too. Chris ate 94.45 grams of protein more than Joshua. With the fat it was really the opposite. Joshua and Chris ate less than the amount they were supposed to. They were lower than the usda by about 107.1 grams. Chris had eaten 7.3 grams of fat less than Joshua. With the sodium Chris and Joshua still tended to eat less than the recommended amount. They had eaten about 28.67 grams less than the usda recommended amount. Joshua had eaten 1.412 grams less than Chris. Sugar was a piece of data that's really spread out. Chris ate 89.05 grams of sugar more than the recommended. Joshua on the other hand ate 181 grams less than the recommended
Jackie’s diet is pretty much the same so l picked the last day. On the first day, she consumed 1374 calories out of 1600 calories depending on her target weight. She did not meet the daily requirement for carbohydrates being the largest class of nutrients, including sugars, starch, and fibers, that function as the body’s primary source of energy. Jackie’s carbohydrate intake was 140.9 grams out of the 300 grams needed, which was 321.9 calories and 23.9 % calories came from carbohydrate. 46% of her diet was fat, 36% being saturated fat, 44% monounsaturated fat and 20% polyunsaturated fat.
Experiment 2: Male and female subjects with long-term (6 months) HFCS access. 150 male and 150 female subjects with comparable BMI levels, daily activity levels and daily medications/vitamins are assigned the same standard diet to follow for a 6 month period. Subjects understand they are to refrain from signicant lifestyle changes during the period of study (includingbut not limited to pregnancy, other diets, exercise regime, new medications/vitamins, etc.). In addition to this standard diet the subjects are instructed to consume either a low level (Level 1) of HFCS each day in the form of a solution, a higher level (Level 2) of HFCS each day in the form of a solution, a low level (Level 1) of sucrose in the form of a solution, or no additions (no HFCS or sucrose). Water consumption is at subject’s discretion. HFCS and sucrose levels are measured daily and body weight is measured weekly. At the end of 6 months on this specied standard diet and HFCS/sucrose intake, blood samples are taken and examined for triglyceridesand insulin, and an updated BMI index is calculated.Data from all groups will be compared using ANOVAs or repeated measures
Also no time-trail difference was projected between the two diets. Ruby stated "Our results show that eating fast food -- in the right amounts -- can provide the same potential for muscle glycogen as sports nutrition products that usually cost more," (Science Daily 1) This experiment does have some limitations such as these individual candidates metabolisms were not taken into consideration, As well, are all of these candidates similar in ways because if they are how can we say that this experiment has a positive outcome because what might work for one individual might not work for another. These details were left out of the report, which has me questioning the actual effect this would have on everyone, maybe this experiment will only work on these cyclists. Furthermore the portions of fast food that were given to these cyclists were not specified, so how will people that believe in these results know how much they can or cannot consume by not sharing this information individuals will consume large portions of fast food which could have an effect on their health as a
This diet suggests aiming for higher protein and carbohydrate consumption on training days and, on rest days, still focusing on protein but, instead, consuming more fat than carbohydrate.
Resistance training has been identified as the most effective method of producicing muscle protein synthesis, resulting in adaptions and growth in the skeletal muscles (Koopman et al., 2006). If combined with correct nutritional intake this can result in increased strength, muscle mass, and cardiovascular fitness. This in turn can lead to an overall improved performance in anaerobic power sports, such as rugby. Traditional resistance training involves carrying out a set of repetitions until failure followed by a suitable rest period before successive repetitions of the same exercise. Supersets, also can be known as agonist– antagonist superset training, consist of performing two exercises on opposing muscle groups which are repeated while limiting the rest period between each exercise. Super sets are a kind of hybrid resistance training method, they increase exercise intensity with shorten rest periods. It has been proven that all three muscle fibers, type 1a, 2a, 2b, can gain substantial hypertrophy from resistance training and super sets (Andrew 2010). An appropriate resistance exercise preparation and use of the important training variables, such as intensity, volume, exercise selection and rest intervals, is necessary for maximizing exercise-induced muscle hypertrophy (Schoenfeld 2010). It is essential to
