Risk factors

Risk factors for developing tendinitis include age, working in particular jobs or participating in certain sports.

Age

As people get older, their tendons become less flexible — which makes them easier to injure.

Occupation

Tendinitis is more common in people whose jobs involve:

• Repetitive motions
• Awkward positions
• Frequent overhead reaching
• Vibration
• Forceful exertion

Sports

You may be more likely to develop tendinitis if you participate in certain sports that involve repetitive motions, especially if your technique isn't optimal. This can occur with:

• Baseball
• Basketball
• Bowling
• Golf
• Running
• Swimming
• Tennis
