Summary

Angiotensin converting enzyme-2 (ACE2) is part of the renin-angiotensin system (RAS), which is involved in maintaining blood flow and electrolyte balance. It has been shown in obese and hypertensive individuals that levels of another molecule Angiotensin converting enzyme (ACE) are much higher, leading to inflammation, fibrosis, vasoconstriction and high blood pressure. ACE2 has a protective effect from ACE, leading to anti-inflammatory, anti-fibrotic and vasodilating effects.

In animal models, it has been shown that aerobic exercise can increase levels of ACE2, while decreasing levels of ACE and offers protection to the cardiovascular system by keeping these two molecules balanced. Although the effects of exercise on the classical arm of the RAS have been studied significantly, ACE2 is a relatively new discovery and has not been studied as extensively in humans. The purpose of this research is to determine the effects of exercise training status on the RAS, specifically on ACE2 and its products.

Conditions

  • COVID-19 Acute Respiratory Distress Syndrome

Interventions

OTHER

VO2 Max test

The participant will be equipped with a vo2 mask or mouthpiece. They will get on the bike and begin with a 5 minute warmup ranging from 30-100 watts. After the warm up there will be a 15-30 watt increase every minute in the cadence that the participant is required to maintain. Once the participant has decided to stop pedalling, the participants mask will be removed to ensure they are feeling well. They will allowed to continue pedaling at their own pace for a cool down for up to two minutes.
