For example, suppose a person has been exposed to COVID-19 but is asymptomatic.
If the person on the same piece of exercise equipment produces less calories for a fixed amount of time than recently usual, could that indicate possible infection (a slight physical weakening)?
If it were indicative, considering the large number of such exercise machines in gyms and homes, might such devices be diagnostically helpful?
Are there studies?

If you e.g. perform significant lower power outputs on an ergometer bike, you are no longer asymptomatic. Generally we should always pay extra attention to patients who experience markedly reduced physical performance.
Yes, Can exercise equipment measure possible
I expect that, as there is a difference between before and after the injury
Luay A. Al-Helaly and Jesper Bondo Medhus, Can we get articles confirming this?
Poor physical performance can be an indicator of e.g. heart, lung, neurological or other medical disorders. Thus, sudden changes in physical performance may reflect previously unknown medical conditions that should be considered.

Performing any type of evaluation through an exercise equipment you can obtain several information about the individual evaluated, including multiple underlying health problems, but it´s difficult with the possibilities available now-a-day to diagnose an asymptomatic COVID-19 patient.
Thank you for your suggestions Jesper Bondo Medhus. However, it would have been good to have research confirming or disproving it in patient with asymptomatic COVID-19.
You're right, it could be very interesting to spot asymptomatic patients. However, my point from the beginning was that patients with markedly reduced exercise performance are not asymptomatic. And we should pay attention to all patients who report markedly reduced exercise performance - covid19 or not.
The symptoms of COVID-19 suggest your performance on an exercise test would be impaired, so by being asymptomatic you are unlikely to see a change. The early symptoms of COVID-19 (i.e. fever, tiredness) could also be indicative of other diseases of ailments so it would be no means be definitive. Patients expressing these early symptoms should seek treatment as they are likely to decline within 5-10 days so an exercise test is not feasible as it would be more important to start monitoring etc. It is a good thought, however. Would be interesting to see.
The bottom line here is that Covid 19 was incorrectly diagnosed as a pulmonary infection which has other manifestations instead of calling it an endovascular multi-organ infection. What do Covid Toes, Malaise or Weakness, GI upsets or any of the other concomitant prodromal signs or symptoms have to do with happy hypoxia Covid 19?.
Any interruption of N=1's "normalcy" could be used to diagnose "asymptomatic" Coronavirus including exercise malaise, fatigue or performance issues.

This article is certainly heading in the right direction which is to use wearable technology to monitor important signs and symptoms of Covid 19.
My questions are:
1. are the signs and symptoms being monitored the best
and most cost effective?
2. how does one manage FN's, FP's, etc?
3. How does the results of the wearable technology data affect treatment?
