As I sit on the sideline with a torn/reinjured MCL (actually sitting on my throne) awaiting my new PT to call back for an initial appt and watching my fitness decline (I’ve been spinning on my stationary bike, but that’s about it), I read about the tour de giro riders dropping out due to covid. I was led to a few journal articles, one of which I skimmed. I think of acute covid as similar to the setback of a minor injury and long covid as potentially “career ending.”
Last summer, it took my middle aged athletic SIL 6 weeks post infection before she could swim across her small home pool. She uses daily lap swimming as a means for maintaining a good baseline fitness. I believe she is near to that baseline now. My wife works with an athlete that has not fully recovered in over a year. They have lingering pulmonary issues (eg, spasms of shortness of breadth) and gets sick pretty often, both are long covid symptoms. I have a coworker who had a stroke in March at age 63. He had (and now has) no personal or genetic indicators of why he stroked (he went through a lot of testing the following month after the stroke) other than having caught mild symptomatic covid a few months earlier.
Here’s a year-old article that focuses on acute mild symptomatic covid and getting back into the saddle, skin track, pool, etc.
“The resumption of physical and sporting activity should be staggered and progressive, both in terms of time and intensity of exercise. An increase of 50% in intensity at the beginning and a gradual increase of 10–30% in the subsequent weeks are recommended [111]. This should allow for a progressive adaptation of organs and systems. A rapid return can cause problems at the neuromuscular level due to insufficient control during dynamic movements being a major risk factor for injury [112], particularly in flexibility-related actions [113]. Therefore, elite athletes can reach high-intensity training while avoiding sudden increases in training load. Nevertheless, a definitive algorithm has not been established yet and more research is necessary to update the proposed framework.
Athletes that have suffered COVID-19 can return to activity once medical diagnosis indicates no pulmonary or cardiac symptoms. One to two weeks of resting is recommended, depending on the cases that were asymptomatic or mild in sportsmen/women. A negative antigen test is mandatory before returning to activity. Several tests under the supervision of a medical doctor are recommended, including [11,25,114,115]: blood test (controlling levels of cardiac markers such as troponin and creatine kinase); electrocardiography, and echocardiography (to discard myocarditis and myopericarditis); 24–48 h Holter monitoring (to discard arrhythmias); lung functional test (to check pulmonary pathology); maximal exercise test (to establish physical fitness). Finally, psychological help could be necessary for particular circumstances or sports disciplines [1].”
