Four weeks post-Covid, are you still very tired, have a headache? This is long covid. Researchers continue to discover Covid along with a new symptom. We will tell you more.

Long Covid affects physical performance

Researchers from the University of California, San and Zuckerberg Hospital in San Francisco analyzed the results of nine studies on long covid effects on physical performance. The physical performance of 359 people infected and cured of Covid was compared with the performance of 464 people suffering from long-term Covid disease. The patients were aged between 39 and 56 years, their body mass index was between 23 and 30 (ie between overweight and obese).

A new symptom

Scientists have identified a new symptom of long Covid: stuffiness during and after physical exercise. Indeed, it seems that Covid reduce oxygen extraction in the muscles. Consequence: irregular breathing patterns and less ability to increase heart rate during exercise.

When comparing the exercise tolerance of the two groups, the peak oxygen level in the long-Covid group was 4.9 ml/kg/min lower than that of the well-recovered group. “Due to prolonged Covid, a doubles tennis player may switch to cart golf or simple stretching exercises for physical exertion,” explains study co-author Matthew S. Durstenfeld in a press release.
