“It is imperative to resume sport slowly and regularly”

10,000 steps or more. In recent weeks, sports doctors and physiotherapists have seen people arriving in their offices with tendonitis, knee, foot, ankle, joint decompensations such as arthritis flares…

In question, a too sudden resumption of physical activity. “We have a marked increase in tendon inflammations of the musculoskeletal system since the post-confinement recovery, notes Doctor Romain Rousseau, sports surgeon at the Institut Nollet (Paris) and president of the French Society for Sports Trauma. The incidence was multiplied by 2 or 3 in consultation of sports medicine. “ In his office, he sees “Two to three people with acute tendonitis per day whereas usually it is one to two per week”.

Same observation for Mathieu Abbot, head of trauma at the sports medicine department of the Clermont-Ferrand University Hospital: “I receive one to two people a day for these reasons, whereas in normal times it is 3 or 4 per week. “ People who wanted to take over ” like before “, without heating. Difficult to quantify however. One case is documented: in the United States, in 2011, the players were unable to train due to a strike action by the National Football League. Twelve ruptures of Achilles tendons were recorded in the first month of resumption of training after eighteen weeks off.

Muscle and cardiovascular loss

Some are less categorical, like Doctor Béchir Boudjemaa, sports doctor at the Hauts-de-France Athletics League: “Certainly, there is joint pain, but not so much more tendonitis than usual. “ Physiotherapists, for their part, see more functional lumbagos, which can be partly linked to confinement. Sitting, which is more common due to telework, does not help.

In any case, “Deconditioning makes the bed of osteo-articular or tendinomuscular injuries”, underlines Mathieu Abbot. Concretely, during a period of inactivity, there is muscle loss, impaired cardiovascular function, deep sensitivity (called “proprioception”), and the elastic capacity of the tendons.

The risk of falling is also increased during rapid movements or on uneven terrain. The reconditioning time is longer. In other words, you lose muscle faster than you gain. After this confinement time of almost two months, it takes about three months to recover, and this by doing sports three times a week.
