ART:075: Elbow Leak Patterns and Their Correction

Executive Summary

The elbow is a critical link in the arm segment of the tennis kinetic chain. Elbow leaks—including insufficient extension, valgus stress, and compensatory patterns—can reduce racket head speed and increase the risk of tennis elbow and other overuse injuries. This article presents the most common elbow leak patterns and provides targeted corrective strategies.

Common Elbow Leak Patterns

Insufficient Elbow Extension

• Observation: The elbow fails to fully extend during groundstrokes and serves
• Cause: Tight triceps, weak triceps, poor timing
• Result: Reduced racket head speed, lower power output
• Correction: Triceps strengthening, extension drills, timing exercises

Valgus Stress

• Observation: The elbow moves into valgus (outward) during the serve and groundstrokes
• Cause: Poor shoulder rotation, weak forearm muscles, improper technique
• Result: Increased stress on the ulnar collateral ligament, tennis elbow risk
• Correction: Technique correction, forearm strengthening, shoulder rotation improvement

Elbow Dominance

• Observation: The elbow compensates for weak proximal segments by overworking
• Cause: Weak trunk rotation, arm-dominant technique
• Result: Elbow overuse, injury risk, reduced power
• Correction: Core strengthening, technique correction, proximal segment emphasis

Practical Application: "The Elbow Check"

During your strokes, focus on feeling your elbow extend fully and in sequence with your shoulder and arm. If your elbow is not extending fully, work on triceps strength and extension drills. If you feel valgus stress at your elbow, work on technique correction and forearm strength. If your elbow is doing too much work, focus on improving your trunk rotation to reduce the load on your elbow.
