What is a significant effect of physical activity on the human body, as noted by researchers?

• A. Decreased energy levels
• B. Increased mood and improved memory
• C. Reduced caloric intake
• D. Less motivation for physical tasks

Answer: (B)

Research has consistently shown that physical activity has profound effects on both the psychological and physiological aspects of the human body. One significant effect is the increase in mood and improvement in memory. Engaging in regular physical activity stimulates the release of neurotransmitters such as endorphins and serotonin, which can enhance mood and reduce feelings of depression and anxiety. Furthermore, exercise has been linked to cognitive benefits, including better memory and enhanced learning capabilities. This improvement in cognitive function is thought to be due to increased blood flow to the brain and the promotion of neuroplasticity, which supports the creation of new neural connections. The other options describe effects that are typically not associated with regular physical activity. For example, physical activity tends to increase energy levels rather than decrease them, support caloric expenditure rather than reduce caloric intake, and generally boost motivation towards physical tasks rather than diminish it.
