The basic principle of motivation is thatGroup of answer choicesathletes need high levels of stimulation to be motivatedathletes are motivated to fulfill their needsathletes need goals for motivationathletics are basically intrinsically motivated

To answer the question step by step, let's analyze each of the given choices:

1. Athletes need high levels of stimulation to be motivated:

   • This suggests that athletes require intense external stimuli to feel motivated. While stimulation can play a role, it is not the fundamental principle of motivation.

2. Athletes are motivated to fulfill their needs:

   • This option aligns with the widely accepted theory of motivation, which posits that individuals are driven to satisfy their needs, whether they are physiological, safety, social, esteem, or self-actualization needs.

3. Athletes need goals for motivation:

   • Setting goals is indeed a significant aspect of motivation, as it provides direction and a sense of purpose. However, it is more of a strategy to enhance motivation rather than the basic principle itself.

4. Athletics are basically intrinsically motivated:

   • Intrinsic motivation refers to engaging in an activity for its inherent satisfaction rather than for some separable consequence. While many athletes may be intrinsically motivated, this is not universally true for all athletes.

Given these analyses, the most comprehensive and fundamental principle of motivation is that athletes are motivated to fulfill their needs. This encompasses a broader range of motivational factors and aligns with established motivational theories such as Maslow's hierarchy of needs.
