Anaerobic exercise sprinting

During sprinting, the following series of events occur  

Phosphates are transferred back to ATP from creatine phosphate for further rounds of muscle contraction. 

Creatine phosphate stores several times the amount of energy that is in ATP. 

Quick ATP synthesis supplies the energy for a few seconds of sprinting. 

Glucose comes from glycogen stores in muscle it is catabo-lized to lactate and released into the circulation. As the ATP decreases in the muscle, the enzyme myokinase interconverts the resulting ADP to salvage one ATP out of two ADP.

ANAEROBIC EXERCISE Exercise that isn t fueled by oxygen intake (as aerobic exercise is). Anaerobic exercise is defined by short, vigorous, and frequent muscle contractions, and includes activities like sprinting and weight lifting. 

Minimum rhabdomyolysis—non-myoglobinuric acute renal failure due to exercise-induced acute renal failure—ALPE (acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise) after sprint, short track event such as 200-m race, etc. 

The other type is non-myoglobinuric acute renal failure, in which intense exercise over a short period of time, such as sprinting, causes minimal rhabdomyolysis without myoglobinuria, i.e., acute renal failure syndrome with severe loin pain and patchy renal vasoconstriction [2]. A recent study showed that anaerobic exercise caused this syndrome, and proposed that Acute renal failure with severe Loin pain and Patchy renal ischemia after anaerobic Exercise (ALPE) (exercise-induced acute renal failure) was a new type of acute renal failure syndrome [4]. 

Recent intense (anaerobic) exercise such as a short-distance sprint. 

As shown in Fig. 54, the types of exercise taken by the patients consisted of a track race (a short-distance sprint such as a 200-m race), soccer, a swimming race, baseball, weightlifting, and a bicycle race, in all of which an intense power output per second or per minute is repeated. However, a single 100-m race was less likely to cause exercise-induced acute renal failure (ALPE). Several 200-m or 100-m races frequently caused ALPE. Repeated anaerobic exercise may be a risk factor. 

The influence of physical activity on nutritional requirements and health is not the same for all activities. For the purposes of this book, exercise will be classified as either anaerobic or aerobic activities. These terms provide descriptive information about both the level of exertion and the duration of the activity and are useful in relating activities to nutritional needs. Anaerobic exercise includes activities such as wei tlifting and sprinting, and involves maximum exertion for periods of time less than 1 or 2 minutes. Aerobic activities are performed for periods usually in excess of 15 minutes at less than maximum speed or strength. 

Two major types of muscle fibers are found in humans white (anaerobic) and red (aerobic). The former are particularly used in sprints and the latter in prolonged aerobic exercise. During a sprint, muscle uses creatine phosphate and glycolysis as energy sources in the marathon, oxidation of fatty acids is of major importance during the later phases. Nonmuscle cells perform various types of mechanical work carried out by the structures constituting the cytoskeleton. These strucmres include actin filaments (microfilaments), micrombules (composed primarily of a- mbulin and p-mbulin), and intermediate filaments. The latter include keratins, vimentin-like proteins, neurofilaments, and lamins. 

Glycolysis produces energy. Michael Johnson sprints to another victory in the 200-meter semifinals of the Olympics. Johnson, like anyone who sprints, requires a source of energy that can be rapidly accessed. The anaerobic metabolism of glucose the process of glycolysis provides such a source of energy for short, intense bouts of exercise. [Simon Bruty/ Allsport.]... 

Sprints and similar short periods of exercise rely on anaerobic metabolism as a source of energy, producing lactic acid. Longer periods of exercise also draw on aerobic metabolism.
