Chronic injury
Injury Prevention: Shoulder (Kozin et al, 2021)
Key Take Aways
✅ Shoulder injury rates were significantly lower in athletes that were utilized a shoulder injury prevention program that consisted of closed chain and eccentric exercises
Population
18 male amateur climbers (18-19 years old)
Summary
🔥 Finding a prevention study is similar to finding the proverbial needle in a hay stack
👉 The selection of closed chain exercise and eccentrics are based on another study that saw a 75% reduction in injuries among women in the army that focused on closed chain gluteal exercises
✅ What is closed chain exercise?
An exercise where the hand is fixed (not moving). An example is a push up. An example of an open chain exercise is a bicep curl, where the hand is free and moving
What closed chain exercises were completed in this study?
1️⃣ push ups on rings
2️⃣ leg supported pull ups
✅ What is an eccentric exercise?
An eccentric exercises is an exercise that uses an eccentric contraction (muscle lengthens as it contracts). An example of this is the lowering phase of a pull up
What eccentric exercises were used in this study?
1️⃣ eccentric pronation/ supination
Things we would like to know
👉 Article doesn’t tell us the intensity or what criteria were used to advance these exercises (if any) for those that want to replicate it’s results
🔥 Mild, moderate, and severe shoulder Injury rates were significantly reduced in the group that completed closed chain and eccentric exercise
