What is exercise?

Exercise

Exercise is the body’s training to improve function and fitness. Exercise and physical activity are commonly used interchangeably. Any energy consumption brought on by the usage of skeletal muscles is referred to as physical activity. Therefore, it covers the entire spectrum of activity, from very low resting levels to maximum effort. Epidemiologic research implies that reported habitual physical activity is linked to reduced blood pressure after controlling for common confounding variables.

Hypertension

High blood pressure

High blood pressure, also known as hypertension, is a frequent illness where the blood’s long-term push against your artery walls is so great that it may eventually result in health issues including heart disease.

Some medical experts identify people as having high blood pressure if their readings are routinely 140/90 mm Hg or above, while others do so if they have readings of 130/80 mm Hg or higher. The initial reading represents the systolic while the subsequent reading represents the diastolic

There are two types

  1. Systolic BP: It gauges blood pressure in your arteries when your heart beats
  2. Diastolic BP: It measures the pressure in your arteries when your heart rests between beats.

Studies on aerobic exercise intervention

Numerous evaluations have been published, and the overwhelming majority of well-controlled trials show that regular aerobic exercise lowers blood pressure in patients with mild-to-moderate essential hypertension compared to non-exercising controls.

Age and Sex Impacts

Age

Middle-aged hypertension patients appear to experience larger exercise-induced blood pressure reductions than either younger or older patients.

Exercise intensity influences

Health care professionals were hesitant to recommend exercise to older or high-risk patients since high-intensity exercise entails a significant risk for cardiac complications. 

Resistance training and hypertension

In recent years, resistance training has gained popularity among elderly men and women. The cause of this is a number of studies suggesting that strength training may be a viable strategy for lowering the risk of falls by reversing or minimizing the age-related reduction in bone mineral density, muscular mass, and power. The research on how strength training affects resting blood pressure (BP) is scarce and contradictory. For instance, strength may have an antihypertensive effect.

A growth in blood pressure is a reaction to exercise

Systolic blood pressure has been shown to be a better predictor of cardiovascular morbidity and mortality than resting blood pressure when it is less than 200 mm Hg at 6 METs of exercise. Recent research indicates that exercise blood pressure responses may be significantly influenced by fitness levels, and that moderate aerobic exercise training may reduce the excessive blood pressure increases that occur during physical activity.

Anti-hypertensive mechanisms of exercise

The fundamental, contentious mechanisms that underlie the hypotensive response induced by exercise training are yet unknown. According to popular belief, exercise training must influence a number of pathophysiological pathways. Overall peripheral resistance, cardiac output, or both may be decreased as a result of that action. 

Conclusion

The results of the most recent studies demonstrate that people with stage 1 and stage 2 essential hypertension can drop their blood pressure with moderate-intensity aerobic exercise training. Systolic and diastolic BP are both reduced on average by 10.5 and 7.6 mm Hg, respectively. There doesn’t seem to be a gender or age difference in the reductions. Following aerobic exercise instruction, patients with stage 3 hypertension have also reported experiencing significant drops in blood pressure and LVH progression.
