Which of the following effects is associated with improved self-esteem from regular physical activity?

Engaging in regular physical activity has been shown to significantly improve self-esteem, primarily due to enhanced confidence and a more positive body image. Physical activity can lead to increased strength, endurance, and overall fitness, which often contributes to how individuals perceive themselves. When people see improvements in their physical capabilities or achieve fitness goals, they tend to feel a sense of accomplishment and empowerment. This boost in confidence often translates into a better body image, as individuals become more comfortable and accepting of their physical appearance.

Furthermore, regular exercise stimulates the release of endorphins, which can improve mood and reduce feelings of anxiety, reinforcing this positive cycle of improved self-esteem. The social aspects of many physical activities can also foster supportive relationships, resulting in greater social connectedness rather than isolation.

In contrast, the other options do not reflect the benefits of physical activity. A decrease in physical capability, increased feelings of isolation, and worsened mood and anxiety levels are contrary to the established benefits of regular exercise, which is associated with enhanced physical health, social interaction, and improved mental well-being.
