Fox and Haskell formula

Anaerobic exercise is used by athletes in non-endurance sports to build power and by body builders to build muscle mass. Muscles trained under anaerobic conditions develop differently, leading to greater performance in short duration, high intensity activities, which last up to about 2 minutes.[1] Image File history File links Question_book-3. ...

Aerobic exercise, on the other hand, includes lower intensity activities performed for longer periods of time. Such activities like walking, running, swimming, and cycling require a great deal of oxygen to generate the energy needed for prolonged exercise to keep you at a certain energy level. Aerobic exercise refers to exercise that is of moderate intensity, undertaken for a long duration. ... For other uses, see Walking (disambiguation). ...

Cycling is the use of bicycles, unicycles, tricycles, quadricycles and other similar wheeled human powered vehicles (HPVs) as a means of transport, a form of recreation or a sport. ...


There are two types of anaerobic energy systems, the ATP-CP energy system, which uses creatine phosphate as the main energy source, and the lactic acid (or anaerobic glycolysis) system that uses glucose (or glycogen) in the absence of oxygen. Events or activity that lasts up to thirty seconds relies almost exclusively on the former, phosphagen, system. Beyond this first thirty seconds the lactic acid system begins to predominate. This provides an inefficient use of glucose, and produces by-products that are thought to be detrimental to muscle function. Continuing activity beyond two minutes becomes aerobic. The lactic acid system can still provide some of the required energy during aerobic exercise, as the body has the capacity to get rid of the anaerobic by-products. The efficiency of by-product removal by muscles can improve through training.[2] Creatine, or creatine monohydrate [NH2-C(NH)-NCH2(COOH)-CH3], is a naturally occurring compound that helps to supply energy to the muscle cells. ... The phosphagens are energy storage compounds, also known as high energy phosphate compounds, are chiefly found in muscular tissue in animals. ...

Lactate threshold (LIP or Lactate Inflection Point)

The lactate threshold (LT) is the exercise intensity at which lactic acid starts to accumulate in the blood stream. This happens when it is produced faster than it can be removed (metabolized). This point is sometimes referred to as the anaerobic threshold (AT), or the onset of blood lactate accumulation (OBLA). When exercising below the LT intensity any lactate produced by the muscles is removed by the body without it building up. The lactate threshold is a useful measure for deciding exercise intensity for training and racing in endurance sports (e.g. distance running, cycling, rowing, swimming and cross country skiing), and can be increased greatly with training. The term Exercise can refer to: Physical exercise such as running or strength training Exercise (options), the financial term for enacting and terminating a contract Category: ...

Structure of the coenzyme adenosine triphosphate, a central intermediate in energy metabolism. ... For other uses of Muscle, see Muscle (disambiguation). ...


Fartlek (speed-play) training and interval training take advantage of the body being able to temporarily exceed the lactate threshold, and then recover (reduce blood-lactate) while operating at below the threshold, but still doing physical activity. Fartlek and interval training are similar, the main difference being the relative intensities of the exercise, best illustrated in a real-world example: Fartlek training would involve constantly running, for a period time running just above the lactate threshold, and then running at just below it, while interval training would be running quite high above the threshold, but then slowing to a walk or slow jog during the rest periods. Interval training can take the form of many different types of exercise and should closely replicate the movements found in the sport.(3) Fartlek, which means speed play in Swedish, is a form of conditioning which puts stress mainly on the aerobic energy system due to the continuous nature of this exercise. ...


Fartlek would be used by people who are constantly moving, with occasional bouts of speed, such as soccer players, while interval training is more suited to sprinters, who exert maximum effort and then can stop exerting completely. With both styles of training, one can exert more effort before fatiguing and burn more calories than exercising at a constant pace (continuous training), but will emphasize training the anaerobic system rather than the aerobic system. Long duration training below the lactate threshold is recommended to primarily work the aerobic system.


Accurately measuring the lactate threshold involves taking blood samples (normally a pinprick to the finger, earlobe or thumb) during a ramp test where the exercise intensity is progressively increased. Measuring the threshold can also be performed non-invasively using gas-exchange (Respiratory quotient) methods, which requires a metabolic cart to measure air inspired and expired. The Respiratory Quotient is used in BMR calculations (basal metabolic rate) and is a form of indirect calorimetry. ...


Although the lactate threshold is defined as the point when lactic acid starts to accumulate, some testers approximate this by using the point at which lactate reaches a concentration of 4 mM (at rest it is around 1 mM) . For other uses, see Concentration (disambiguation). ... For other uses, see Concentration (disambiguation). ...


Weights and reps

When anaerobic exercise occurs in the context of physical training, the terms weight and reps are generally used to refer respectively to the amount of weight moved (either pushed or pulled), and the number of times the action of moving it is repeated within a short period, between breaks. In most educational systems, physical education (PE), also called physical training (PT) or gym, is a course in the curriculum which utilizes the learning medium of large-muscle activities in a play or movement exploration setting. ... For other uses, see Weight (disambiguation). ...

anaerobic exercise (288 words)
Anaerobic exercise is any exercise that requires short bursts of power, such as all-out sprinting or very heavy weightlifting.
Anaerobic means "without oxygen." The ability to perform this type of work is not dependent on oxygen from the air, but relies on energy sources stored in the muscle.
With a primarily anaerobic exercise such as sprinting, after about 90 seconds, you begin gasping for air and feel a burning sensation in your lungs — your body is forcing you to stop exercising.
