High intensity workouts generally increase the risk of complications during exercise for unconditioned participants because these individuals may lack the cardiovascular fitness, muscular strength, and overall conditioning required to handle the stress that comes with more vigorous exercise. When unconditioned participants engage in high intensity training, they may experience acute responses such as excessive fatigue, elevated heart rate, and elevated blood pressure, which can lead to a higher likelihood of injury or other complications. It's crucial to understand that unconditioned individuals' bodies are not acclimated to high loads and stresses associated with intense workouts. Therefore, promoting a gradual introduction to physical activity through lower intensity exercises allows the body to adapt appropriately, enhancing physical capabilities and reducing the risk of adverse events. Proper progression in activity intensity and volume is vital to safely accommodate individual limits and promote overall fitness gains while minimizing risks.
