Treppe
The phenomenon of increasingly stronger contractions owing to increased stimulus strength is called recruitment. It involves activating more muscle fibers within a muscle to generate greater force in response to a stronger stimulus.
The phenomenon you are referring to is called the second stimulus before relaxation, which causes increased force, is known as the treppe effect or the staircase phenomenon. This is characterized by the successive increase in muscle contraction force when muscle fibers are stimulated with increasing frequency.
A subthreshold stimulus is one that does not generate a strong enough signal to elicit a perceptible contraction in muscle fibers. It is below the threshold required to cause an action potential and result in muscle contraction.
The stimulus package in the US has increased spending.
A twitch contraction is a single, brief contraction of a muscle fiber in response to a stimulus. It is the smallest unit of muscle contraction and is not strong enough to produce movement of a limb.

it is known as the threshold stimulus usually seen in tonic contraction
The minimum stimulus needed to cause a contraction is called the threshold stimulus. This is the minimal level of stimulation required to activate muscle fibers and initiate a contraction response.
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
The first phase after a stimulus in a muscle contraction is excitation-contraction coupling. This involves the transmission of the action potential along the sarcolemma and the release of calcium ions from the sarcoplasmic reticulum.
a change of temperature.
A submaximal stimulus refers to an intensity level of a stimulus that is below the maximum level that a system or organism can respond to. It is often used in exercise physiology to describe a workload that does not elicit a maximal performance or physiological response.
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
