Resistance training has a profound positive impact on cardiovascular health in seniors by improving heart function and lowering blood pressure. Engaging in regular resistance training helps enhance the efficiency of the cardiovascular system, allowing the heart to pump blood more effectively. This leads to improved oxygen delivery to the muscles and a reduction in resting blood pressure, which is crucial for older adults who may be at higher risk for hypertension and other cardiovascular diseases.

Additionally, resistance training promotes greater muscle mass and strength, which can contribute to an overall increase in daily physical activity. The enhancement in muscular strength can lead to improved performance in daily activities and a reduced risk of falls, which is particularly important for seniors. As they maintain a more active lifestyle, their cardiovascular system benefits through improved overall heart health, increased circulation, and better regulatory responses to physical activity.

The other options do not align with the benefits of resistance training. For instance, increasing resting heart rate is generally a negative outcome and would not be expected from regular, effective resistance training. Similarly, a decrease in blood circulation contradicts the established benefits of physical activity, which enhances blood flow and cardiovascular health. Lastly, while concern about joint strain is valid, it is not an inherent outcome of resistance training when performed correctly; instead, proper resistance training technique
