Short term endurance is also called:

Short term endurance refers to the ability of the body to sustain physical activity over a short period of time, typically lasting a few minutes to a couple of hours. It is an important component of physical fitness and is often measured in terms of the body's ability to perform high-intensity activities for a short duration without fatigue.

There are different terms used to describe short term endurance, including:

1. Anaerobic endurance:
Anaerobic endurance refers to the body's ability to perform high-intensity activities that rely on the anaerobic energy systems, which do not require oxygen. This type of endurance is necessary for activities such as sprinting, weightlifting, and high-intensity interval training (HIIT). Anaerobic endurance is characterized by short bursts of intense effort followed by periods of rest or recovery.

2. Muscular endurance:
Muscular endurance refers to the ability of a specific muscle or group of muscles to perform repeated contractions over an extended period of time. It is often measured by the number of repetitions or the length of time a muscle can sustain a contraction before fatigue sets in. Muscular endurance is important for activities such as running, swimming, and cycling.

3. Aerobic endurance:
Aerobic endurance, also known as cardiovascular endurance or cardiorespiratory endurance, refers to the body's ability to sustain prolonged exercise that requires oxygen. It involves the efficient delivery of oxygen to the muscles and the ability of the muscles to utilize that oxygen to produce energy. Activities such as long-distance running, cycling, and swimming rely heavily on aerobic endurance.

Both (a) and (b):
The correct answer to the question is option 'D', which states that short term endurance is also called both anaerobic endurance and muscular endurance. This is because short term endurance can be achieved through the combined development of both the anaerobic and muscular systems in the body. Anaerobic endurance is important for high-intensity efforts, while muscular endurance is necessary for sustaining repeated contractions over time. By developing both types of endurance, individuals can improve their overall performance in activities that require short term endurance.

In conclusion, short term endurance can be referred to as both anaerobic endurance and muscular endurance, as they both play a significant role in sustaining high-intensity activities over a short duration.
