Understanding The Science of Movement for Athletic Performance

Muscles, with their rich blood supply, heal relatively quickly. This graphic provides estimated timelines for muscle recovery, from exercise-induced soreness (0-3 days) to a severe Grade 3 strain (9-12 months).

Tendon injuries, like tendinitis, have a longer recovery timeline due to their limited blood flow. Healing can range from 2-6 weeks for an acute issue to over 4 months for a surgical repair.

Ligaments provide joint stability, and their healing time varies significantly with the severity of the sprain. A mild Grade 1 sprain may take 2-8 weeks, while a full Grade 3 tear or surgical repair can take 6-12 months or more.

Bone fractures typically require 6-12+ weeks to heal, providing the structural support for the body to rebuild. Proper loading during rehab is key to ensuring a full recovery.

Cartilage and meniscus injuries are among the slowest to heal due to very poor blood supply. Recovery can take anywhere from 3 to 24 months, highlighting the importance of patience and a structured rehab plan.

Knee valgus, or the inward collapse of the knee, is a significant risk factor for injury in athletes. This educational series breaks down the key facts every athlete should know about this common movement fault.

This graphic defines knee valgus mechanically, explaining how the inward collapse occurs due to a combination of femoral internal rotation and tibial external rotation, creating the characteristic "knock-knee" appearance during movements like squats and jumps.

We explain the common causes of knee valgus, which include weak gluteus medius muscles, limited ankle mobility, and poor motor control. These factors are particularly common in youth athletes and post-growth spurt females.

The risks associated with knee valgus are significant. Athletes with this movement fault are more vulnerable to ACL tears, patellofemoral pain, and meniscal injuries. Research shows it can increase ACL injury risk by 2.5 times in cutting sports.
