Anaerobic system – This system predominates in supplying energy for intense exercise lasting less than two minutes. It is also known as the glycolytic system. An example of an activity of the intensity and duration that this system works under would be a 400 m sprint. Aerobic system – This is the long-duration energy system.
The body uses this energy pathway for lower intensity exercise that lasts longer than three minutes, which corresponds to the rate at which the body produces ATP using oxygen. [3] This energy system is essential to endurance athletes such as marathon runners, triathletes, cross-country skiers, etc.
A hybrid athlete is an individual who possesses a balance of both strength and endurance. They possess a diverse set of skills and abilities, distinct from specialized athletes such as bodybuilders or marathon runners. Instead, these athletes prioritize overall fitness, seeking to achieve a well-rounded level of physical capability.
Power training frequently specifically utilises two physiological processes which increase in conjunction with one another during exercise. These are deep breathing, which results in increased intra-abdominal pressure; and post-activation potentation, which is the enhanced activation of the nervous system and increased muscle fibre recruitment.
Powerlifting is a competitive strength sport that consists of three attempts at maximal weight on three lifts: squat, bench press, and deadlift.As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single-lift effort of a barbell loaded with weight plates.
The CrossFit Games is an annual athletic competition owned and operated by CrossFit, LLC. [1] Athletes compete in a series of events at the Games, which may be various standard CrossFit workouts consisting of metabolic conditioning exercises, weightlifting, and gymnastics movements, as well as a range of activities from other sports such as swimming, road cycling and strongman.
Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.
Properties of isolated, closed, and open thermodynamic systems in exchanging energy and matter. A thermodynamic system is a body of matter and/or radiation separate from its surroundings that can be studied using the laws of thermodynamics. Thermodynamic systems can be passive and active according to internal processes.
