A form of exercise that involves short, intense bursts of energy; anaerobic exercise can only be maintained for 1–2 minutes, slightly longer through specific anaerobic training. Anaerobic exercises are generally used to build muscle mass, increase muscular strength, speed and power, for example sprinting (running, cycling, swimming, etc), and bodybuilding. A. Anaerobic Exercise
B. Aerobic Exercise

A). Anaerobic Exercise.

Explanation:

Anaerobic Exercise is characterized as the exercise that aims to break down glucose without making use of oxygen. Such exercise involves short, quick, and intense bursts of energy with maximum efforts. This leads to the body needing immediate energy(except oxygen) to fuel itself that eventually leads to the break down of glucose. This exercise primarily aims to 'build the mass of the muscles or enhance the muscular strength, through short and intense workouts involving jumping, sprinting, running, cycling, etc. Therefore, option A is the correct answer.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
