Why Do Calf Injuries Happen and Who's Most at Risk?
Published: Dec 27, 2023
Calf injuries are common among athletes and active individuals, but understanding why they happen can help prevent them. This article explores the causes and risk factors of calf injuries.
Contents
What Causes Calf Injuries?
Calf injuries often occur during sudden movements like sprinting or jumping, especially when the muscles aren't properly warmed up. In sports such as tennis and football, these movements are frequent, making injuries more likely. The gastrocnemius muscle, which helps with jumping and sprinting, is particularly prone to injury.
Who Is Most at Risk?
Middle-aged male athletes, especially those not in peak condition, are at higher risk for calf injuries. Older runners and those with a forefoot strike pattern are also more susceptible. The risk increases with age and previous calf injuries.

Sports and Calf Injuries
Certain sports have a higher incidence of calf injuries. Tennis and football players frequently experience them, with 'tennis leg' being a common term. In Australian football, calf injuries are the second most common muscle injury.
