Answer:

Definitions:

1. Intensity

In physics, intensity of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre, or kg⋅s⁻³ in base units

2. Frequency

Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency.

3. Overload

: to load (something or someone) to excess: such as. a : to put too large a load on or in (something) overload a ship overload a washing machine Overloading the trailer poses a safety risk. … a bad winter can so overload roofs with snow that their collapses become endemic.—

4. Muscle Failure

Muscle failure is the point when your working muscle is fully fatigued to the extent that it can no longer complete another repetition of a movement with strict biomechanics.

Examples:

1.Intensity

An example of intensity is having the ability to run miles on end at a top speed. An example of intensity is how quickly a treadmill is moving.

2.Frequency

A frequency is the number of times a data value occurs. For example, if four people have an IQ of between 118 and 125, then an IQ of 118 to 125 has a frequency of 4. Frequency is often represented by the letter f.

3.Overload

An example of a program that uses the overload principle would be one that prescribes squatting a prescribed weight for five sets for one week, moving to squatting a slightly heavier load for five sets the next week, and progressively increasing the loads each subsequent week.

4.Muscle Failure

You can also weave failure training into regular workouts by picking a muscle group or an exercise (such as push-ups, biceps curls, or triceps dips) and seeing how far you can go. But remember that even if you don't lift to failure, you're still doing something good for your body when you lift weights.
