Final answer:
Artificial altitude training at sea level can be beneficial for nonelite athletes by simulating high-altitude conditions to stimulate physiological changes, although effectiveness varies. Exercising in water is suggested as an alternative that is easier on the joints.
Step-by-step explanation:
The practice of artificial altitude training at sea level, which involves creating conditions similar to those at higher altitudes (such as reducing the oxygen content in the air), can be beneficial for nonelite athletes. The rationale behind this training is that it may stimulate physiological adaptations that increase the body's efficiency in using oxygen, potentially improving endurance and performance. However, it is important to note that while some studies have suggested benefits, the effectiveness of this kind of training can vary greatly between individuals. For nonelite athletes, modifications to their training program, like exercising in water, are often recommended for minimizing stress on joints while also improving fitness.
Figure 14.7.7 indicates that water exercises provide buoyancy which helps to reduce the stress on joints, offering a different form of beneficial low-impact exercise. These forms of exercise can be particularly valuable for joint health and can be included as part of a diverse training regimen. Both artificial altitude and water exercises may serve as valuable components in an athlete's training, although the specific benefits and best practices for incorporating them can depend on the individual athlete's goals, fitness level, and overall health.
