Skill-related fitness levels are influenced by body composition and the ability to manage stress, with body composition affecting exercise performance and stress management ability impacting exercise consistency.
Step-by-step explanation:
Two factors that can influence your skill-related fitness levels include body composition and the ability to manage stress. Body weight and composition impact an individual's fitness by affecting their ability to perform certain exercises; for instance, athletes may require different physical compositions for optimal performance in their respective sports. Additionally, maintaining a balance between the intake of energy and protein is crucial for manipulating physique for athletic purposes. On the other hand, psychological factors such as stress management can have a significant influence on fitness levels.
