Success in sport competition such as a 220-yd sprint run requires a highly trained: a. aerobic energy system

b lactic acid energy system

c. ATP-CP energy system

d. b and c

The correct option is lactic acid energy system

Explanation:

The option chosen as the correction is "b lactic acid energy system" since in sprint races the distance is short, or relatively short as in this case they are two and a half blocks or 220mts, in these short distances the contraction Muscle is of high potential, activates the red muscle fibers that are the tools that specialize in explosive contraction with few demands on oxygen, a difference from the white ones that are the opposite (these work at a medium concentration of oxygen and low contractions sustained power over time).

Red muscle fibers contract very powerfully and with few oxygen requirements, but this implies a higher production of lactic acid for the athlete, because this acid is the product of anaerobic contraction.

Muscle contraction with few partial pulsations of oxygen generates accumulated sorts between the muscle fibers of lactic acid, and is the well-known post-exercise pain of athletes.

Athletes who train for sprint challenges also consume glucose rapidly consumed to improve the effectiveness and power of contraction.

Furthermore, the oxygen requirements are few because, as it is a high potency and short duration activity, it does not give the body time to supply the partial oxygen pressures that are completely needed.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

the answer is c most of the fortnite players usually buy v bucks to get the battle pass and other cosmetics but some players who are referred to as "no skins" don't   buy skins and are usually noobs.
