At least in my circles, I have heard recently of some long-time local exercisers who are having trouble getting back to their regular exercise after having COVID. While it seems that most have bounced off of it and able to return to normal activities, at least the concept of a slow return to normal is widespread and also getting some national attention.

While most have listed at least a month of poor exercise following COVID, some are lingering much longer with no apparent reason otherwise. Health magazine has reported that long COVID can drastically reduce a person’s capacity for exercise and physical activity. Researchers analyzed 38 different studies on how long COVID affects exercise and their recovery. Findings say that exercise intolerance can steal away up to a decade of exercise ability.

“This roughly translates to the expected decrease in exercise capacity by aging one decade,” lead study author Dr. Matthew Durstenfeld, a cardiologist and clinical researcher in the department of medicine at the University of California. This could look like going from the ability to do light jogging to only being able to do a brisk walk, he added. While this may not be the case for everyone with long COVID, it does show that long COVID’s impact on exercise is varied and can be extreme.

“As this is an average, some people experience no decrease in exercise capacity at all,” Durstenfeld said. “And others experience a really profound decrease in what activities they can do. It’s associated with heart and lung function and is a common symptom of many chronic diseases including type 2 diabetes and heart failure.”

Regarding long COVID and exercise intolerance, Durstenfeld and his colleagues looked into the connection after seeing participants of another study — the Long-Term Impact of Infection with Novel Coronavirus study — regularly report that they weren’t able to exercise as much or at the same intensity as they had before having COVID.

“For some, it was going from being an elite cyclist to ‘normal,’ and for others from being able to exercise normally to an inability to do their regular activities,” Durstenfeld said.

Researchers analyzed 38 different studies with a total of 2,160 participants, and ultimately homed in on nine studies including 464 individuals with symptoms of long COVID and 359 without. The studies relied on cardiopulmonary exercise testing (CPET) to measure exercise capacity, specifically their peak oxygen consumption (V̇o₂).

Researchers found differences in the peak Vo₂ among people who had symptoms of long COVID more than three months after a bout of COVID, and those who did not. Researchers also said the reduced exercise capability goes beyond just deconditioning, or the physiological changes that come after a period of inactivity. People also experienced dysfunctional breathing, chronotropic incompetence (inability to increase heart rate during exercise) and impaired oxygen uptake and utilization.

As with most information surrounding long COVID, much is still unknown about the condition — including its connection to exercise intolerance. “No single mechanism emerged as to why long COVID contributes to a decrease in exercise capacity,” Durstenfeld said. He and his colleagues concluded that more research needs to be done on the connection, but that exercise intolerance should be considered a potential symptom of long COVID.

If you suspect you are affected, please see your doctor for the latest treatment.

The self-defense training clinic offered by Sidekick Karate and the Salisbury Rowan Runners is filling up. While planned as a result of recent female runner deaths nationwide, the session is open to men as well. The training clinic will be held on Saturday, Nov. 4 at Sidekick Karate from 10 a.m. to noon. Reserve your spot by emailing me at david.freeze@ctc.net . Look for this and other activities at www.salisburyrowanrunners.org .

The topic of self-defense, especially for women, has become a highly discussed topic with the recent killing of Eliza Fletcher who went out for a 4 a.m. run and did not return. Fletcher was a teacher and mother of two when abducted in her hometown of Memphis, Tennessee. Her body was found later after she was forced into a dark-colored vehicle. At least six female runners and one female golfer playing alone have been killed in recent years.

The dangers women face while simply exercising outside are in the spotlight again and locally the Salisbury Rowan Runners and Sidekick Karate are offering a self-defense seminar and training session on Nov. 5. The event will be held at Sidekick Karate at 520 South Main Street from 10 a.m.-noon. There is no charge and both men and women are welcome. You do not have to be a walker or runner to attend. A limited number of spots are available. Please reserve yours by emailing me at david.freeze@ctc.net

Most runners, at least at one time or another, want to train to get faster. Working to get faster is hard and often painful, but commitment to a good plan is usually successful. Training to get faster almost always pays off relative to the amount of time and effort invested.

I used to read Runner’s World religiously and other related magazines until it seemed they were recycling the same ideas over and over and just titling them differently. It remains my belief that runners in general used to train harder and push themselves more. Yes, it is a different time, but we all want to be good at something and what is better than any benefit to your physical and mental health?

Last week, I ran across what a Navy Seal teaches to his trainees when they must break very fast mile times, particularly when a lot of them are large men. Usually the bigger the body, the harder it is to run fast. Navy Seals have to train for a 1.5-mile time trial clocking of 9 minutes, that’s 6 minutes per mile. Here is what Navy Seal trainer Stew Smith says: This is a workout for conditioned athletes, so dial yours back to something doable and in line with your abilities but keep with the basic plan. I am going to do this once a week.

Warm up with the following — Keep going up the ladder until you reach set 10.

• 1 squat, jog 100 meters
• 2 squats, jog 100 meters
• 3 squats, jog 100 meters

Then repeat the below workout four times:

• Run 400 or 800 meters at goal pace. If you choose, you can do the squats and lunges every other set.
• Squats: 20
• Lunges: 10 per leg
• Stretch as needed but at minimum rest between sets

You could begin with four 400-meter runs and do the squats and lunges every other set. Then work your way up.

After you complete the middle segment, finish the full pyramid that you started with and use it as a way to push a faster run pace for shorter distances. The final section looks like this:

• 10 squats, run 200 meters fast. You aren’t sprinting but running faster than your goal pace.
• 9 squats, run 200 meters
• 8 squats, run 200 meters

Keep going to one squat and a total of 10 x 200-meter runs.

This workout will be most easily accomplished on a track. 100 meters is one quarter of the track, 200 is about half the track and 400 is one complete lap. Of course, the secret to this workout is the squats and lunges. You are waking up leg muscles while stretching them out as well.

Look for this coming weekend’s two races, Saturday’s St. Matthews 5K on Oct. 29 and Sunday’s Spooky Sprint at Salisbury Community Park on Oct. 30 at www.salisburyrowanrunners.org.
