Running health: The importance of strength training and joint care

Running and strength training are increasingly integrated to improve athletic performance and mitigate injury risks. While running is a repetitive, high-impact activity, the impact on joints—specifically the knees—depends on individual factors such as muscular preparation, body alignment, and previous injury history.

Orthopedist Luiz Felipe Carvalho notes that running does not inherently cause joint damage; rather, the effects depend on whether the joints are healthy and well-prepared. A significant risk factor is running with compromised joints without sufficient muscle strengthening. Additionally, abrupt increases in training intensity or volume can lead to overload for those not yet adapted to the activity.

Effective integration of strength training is crucial. Simply performing weightlifting is not the same as specialized strength training for runners. Proper exercise selection, load control, and session distribution are necessary to ensure that strength work serves as an ally to running rather than a source of additional fatigue.
