There are differences between Level 2 and Level 1 swimmers in the following aspects:
Performance Standards: Level 1 athletes have a higher performance standard than Level 2 athletes. This is the most immediate and significant difference, and Tier 1 athletes often need to achieve a higher score in the competition in order to receive the corresponding rating.
Training volume and intensity: Level 1 athletes typically train more than Level 2 athletes. This is because they need a higher level of physical fitness and skill to maintain and improve their competitive level.
Skill level: Level 1 athletes typically have a higher level of skill relative to Level 2 athletes. They may have finer technical movements, a better sense of water, and more efficient swimming skills.
Tournament experience: Tier 1 athletes tend to have more experience competing than Tier 2 athletes. They may have competed in more competitions and achieved better results at higher levels.
Mental Fitness: Level 1 athletes are generally stronger than Level 2 athletes in terms of mental qualities. They may have better ability to work under pressure, self-regulation, and match focus, which helps them perform at their best in the game.
Coaching and training plans: Level 1 athletes may have more specialized coaches and more personalized training plans to meet their higher training needs. Whereas Level 2 athletes may receive more general training and instruction.
Note that these differences are not absolute, but rather a general trend. The specific situation may vary depending on the athlete's individual circumstances, training conditions, and other factors.
