Elbow

  • Tendonitis, lateral epicondylitis / gripping, posterior impingement from locking elbows out
  • Ganglion cysts
  • callouses, skin abrasions

Biceps tendon rupture. High risk with eccentric muscle contraction: muscle is elongating or getting longer, yet you are contracting it at the same time. This can happen with pullups, chest to bar, muscle ups, skin the cat on the rings.

The biceps tendon can tear up by the shoulder (rupture of the long head of the biceps) or tear by the elbow. The shoulder tears usually heal on their own and don’t require any specific intervention. They can result in a popeye muscle deformity but strength is only marginally diminished. Many professional athletes continued to be competitive after sustaining such injuries. The distal biceps tear, however, which occurs at the elbow, is different. Tearing here often results in weakness in elbow flexion AND elbow supination (turning your palm up to the sky). We’ve seen several distal biceps tears while doing deadlifts as well: see the blog post on the topic.

Lateral epicondylitis (tennis elbow) and Medial epicondylitis (golfer’s elbow) are commonly associated with prolonged gripping activities. With all the gripping involved in CrossFIt, the best advice re prevention is: don’t forget to warm up your grip, stretch your forearm muscles, learn the hook grip and seek care for elbow pain that won’t go away.

Your Body & Injury

Elbow

The biceps tendon can tear up by the shoulder (rupture of the long head of the biceps) or tear by the elbow.

Foot and Ankle

Achilles Injuries. Most commonly, CrossFitters will sustain overuse tendinits.

Hips

CrossFit and Plyometrics involves a fair amount of squatting and crouching. Wallballs, slam balls, olympic power lifts, eg squat cleans etc, all involve ‘dropping down low’ and getting your hip crease below knee crease.

Knees

Knees are more than just the platform that supports our stance, run and squat.

Muscle

Muscle physiology is a complex science. There are fast twitch, slow twitch muscle fibers and elaborate mechanisms of enhancing strength, power, endurance speed and fatigue resistance of muscle.

Shoulder

There are two labra or labrums in the body. They are both at somewhat high risk in the Sports of Fitness activities which involve a lot of deep squatting and overhead lifting.

Spine

The spine is a complex anatomic masterpiece of axial structural support for our body.

Wrist

Sprains and tendonitis are the most common ailments.
