Final answer:
Physical activity contributes to the delay in the development of cardiovascular disease by reducing risk factors and improving overall health. Just 30 minutes of daily exercise can lower heart attack risk, and exercise has additional systemic benefits, including hormonal balance and inflammation reduction.
Step-by-step explanation:
Studies indicate that physical activity has a positive effect on the delay in development of cardiovascular disease. Exercise is known for reducing risk factors like hypertension, high total cholesterol, and bad cholesterol, while increasing beneficial high-density lipoproteins, insulin sensitivity, and the heart's efficiency. Not only does it reduce the likelihood of developing certain conditions, but it also plays a key role in promoting overall health by improving cardiovascular and muscular fitness, bone density, cognitive function, and aiding in weight management.
Engaging in as little as 30 minutes of exercise daily, even if not continuous, has shown to significantly lower the risk of heart attacks. This highlights the importance of regular physical activity regardless of body weight. Furthermore, exercise releases myokines from contracting muscles, aiding in tissue repair and reducing inflammation, thereby contributing to vascular homeostasis and lowering the risk of diseases like type 2 diabetes, obesity, and certain types of cancer.
The recommended level of physical activity for adults for substantial health benefits, according to the 2018 Physical Activity Guidelines for Americans, includes at least 150 to 300 minutes per week of moderate-intensity aerobic activity, muscle-strengthening activities, and spreading this activity throughout the week for better results.
