Final answer:
Two groups in the Linden, Lenz, and Con (2001) study that didn't receive stress management training showed significantly reduced stress levels, highlighting the benefits of perceived control, physical fitness, and stress reduction techniques like regular exercise.
Step-by-step explanation:
In the Linden, Lenz, and Con (2001) study mentioned in the context of stress management and physical health, the two groups that did not receive the stress management training exhibited a significant reduction in stress levels. This finding aligns with the extensive body of research indicating that higher levels of perceived control and physical fitness are associated with lower stress reactivity. Such research underscores the importance of perceived control, social support, and physical fitness as protective factors against the negative impacts of stress on well-being. For instance, regular exercise is recognized not just as a method to enhance physical health but also as an effective stress reduction technique, which correlates with improved psychological resilience and quicker recovery from stress-related challenges.
