Metabolic rate is said to be determined by body size and often the temperature of the organism. Often there is one generic slope that scientists associate with the slope in oxygen consumption and metabolic rate, but their has been speculation on whether that number changes with body size and what type of organism it is. The resting metabolic scaling exponent for mammals and many other species is usually .75. Over the years many different studies have been done finding different scaling exponents

In highly trained individuals, increased work of breathing, respiratory muscle fatigue and dyspnea at high intensities limits the respiratory system performance. During strenuous exercises, moderately fit subject’s respiratory musculature demands ~10% of the total oxygen consumption (VO2) whereas highly fit subject demands up to 15% of VO2. The exhaustive high-intensity exercise leads to inspiratory, expiratory muscle fatigue as well as diaphragm fatigue (above 85% VO2max or 80% Wmax). Low ability

The body needs more oxygen when exercising because when you start to move your muscles will start producing energy from breaking down glucose to aid with the movement. If there is an insufficient amount of oxygen getting to the muscles then they will look for another way to produce energy. This can result in the production of lactic acid which causes cramping in the muscles or if you’re doing intense exercise then you could cause lactic acidosis which is harder to burn off. The body needs to remove

Athletes are always looking for competitive advantages to get better. Training at high altitude has been used by competitive athletes as a means of improving their potential. During workouts at high altitude, athletes feel like putting more effort to perform compared to working out at sea level. The increased rate of perceived exertion is caused by altitude-induced hypoxia, which is a decrease of oxygen being delivered to the muscles to create energy. As elite athletes acclimate to high altitude

The BFS (bigger, faster, stronger) is a program created to increase an athlete performance by creating specific workouts that will improve strength, power, speed, agility, and flexibility. The athlete during the training period tries to break PR’s (personal records). These type of training is not for any regular person, it is an intense 4 weeks cycle in which the athlete trains 5 days per week and weight trains twice per week. The workouts are full body, movements that required the entire body to

Hypertrophy Hypertrophy is the enlargement of an organ or tissue from the increase in size of its cells. For example, muscle is made out of fibers and those fibers are made up of a ton of thicker fibers. So when they bond together they make tight bundles of tissue. Also there are two types of fibers there are fast twitch and slow twitch. The fast twitch fibers are for endurance and the slow twitch are for strength.For example a sprinter has more fast twitch fibers.So a distance runner has more slow
