Hamstring Muscle
Characteristics
-
-
-
-
-
-
-
Biceps femoris most prone to injuries as its capacity to produce large eccentric force at moderate speed
-
As speed increases during running , more eccentric force is required to be produced
Intrinsic Risk factor
-
-
Imbalance of forces
-
Functional ratio
where quadriceps at 240 degrees/second concentric and hamstring at 30degreees/ second eccentric were considered to be more closer to real world
Untreated imbalances posed a risk of 4.6 times greater compared to treated players with a risk of 1.44 times.
-
Peak torque angle
More closed in non-injured leg than injured leg , thus posing a repeated injury risk, owing to scar tissue
Flexibilty
Only flexibility training has no effect , should be combined with eccentric traning
-
Training
Fatigue :Post exercise recovery , intra exercise recovery
Angle of max force production in the length tension relationship – increase sarcomere in series and increase tolerance to negative fatigue ( eccentric)using low load high speed eccentric.
Pelvic Modifications while running – Optimize pelvic position while running using gluteus maximus activation.
Maximum speed , acceleration and braking- ability to repeat sprint, accelerate and change of direction.
