Lacrosse is a dangerous sport with a high threat of injuries such as ankle sprains, head and face contusions, concussions, knee sprains, wrist fractures, hip flexor strains, and lower back pain. If a player trains and conditions correctly, then they could avoid some of these serious injuries.

Different positions call for specific conditioning and training because of the skill sets. For example, an attacker will need to train with quick and sudden movements, while a midfielder will need to train with more endurance based activities for the amount of running needed in that position. A defender will need to train to be sturdy and not let other players get by them so they can protect the opposing team from scoring a goal. 

Sprained ankles are commonly caused by falling or getting crushed by another player. A sprained ankle is an injury that occurs when you roll, and it can stretch or tear the tough bands of tissue that hold together your ankle bones. A sprained ankle occurs when the ligaments are moved passed their normal range of motion.

Another injury that is common in lacrosse is concussions which is a traumatic brain injury that affects concentration, memory, balance, and coordination. In lacrosse, these are most commonly caused by body checks, unprotected contact, and collisions to the head by a ball.

Also common in lacrosse is a knee sprain, which is an injury of the ligaments and tough bands of tissue that connect the bones of the upper and lower leg at the knee joint. These injuries can occur when players cut and dodge in the game, and because of the lack of protection on the knee, this injury occurs often.
