Jõulisus

Jõulisus is a noun in Estonian that denotes the quality or state of being powerful, strong, or vigorous. It can refer to physical strength, energy, or the forcefulness of an action, and it is used in everyday speech as well as specialized contexts such as sports science, rhetoric, and art. The word is built from the root jõud (power, strength) with the abstract noun suffix -lus, and it is used to describe both bodily capacity and the manner in which something is performed.

In sports and fitness contexts, jõulisus often describes the ability to generate force rapidly and effectively during a move, such as in jumping, lifting, or sprinting. It is related to, but not identical with, speed or endurance; as a trait, jõulisus emphasizes intensity and decisive action rather than duration alone.

In rhetoric and communication, jõulisus denotes forcefulness of expression—clear, confident, and assertive delivery. In literature and the arts, it can refer to a dynamic, energetic style that conveys power or drive.

There is no single quantitative measure of jõulisus; assessment is qualitative in everyday language and may be supported by objective metrics in sport science, such as peak power outputs or strength tests. Related concepts include jõud (power), tugevus (strength), and energia (energy).
