Final answer:
Crossfit's 3 Dimensional Definition of Fitness does not have an official three-pronged definition that fits the provided options; instead, it focuses on varied functional movements and high-intensity workouts that develop multiple fitness domains, including muscular strength and endurance as well as cardiovascular fitness.
Step-by-step explanation:
Crossfit's 3 Dimensional Definition of Fitness is a comprehensive approach to physical well-being, emphasizing the importance of varied functional movements and high-intensity workouts. While Crossfit itself does not define its fitness in only three dimensions, its philosophy encompasses various aspects of fitness. The options provided in the question do not directly map to Crossfit's official statements but can be related to its general principles.
Exercise categories affect three different attributes of fitness: muscular strength, muscular endurance, and cardiovascular/respiratory endurance. Muscular strength refers to the maximum amount of force that a muscle can exert in a single effort, while muscular endurance is the ability of a muscle to sustain repeated contractions or to continue to apply force against a fixed object. Furthermore, functional movements and high-intensity workouts also contribute greatly to cardiovascular fitness, which involves the efficiency of the heart, lungs, and blood vessels.
It is important to note that while flexibility, speed, power, agility, and skill are significant components of fitness, they are not explicitly highlighted in the commonly referred to 'three-dimensional definition' of fitness in Crossfit. However, Crossfit does aim to develop these attributes through its diverse and inclusive program designs.
