Young
female athletes are 4 to 6 times more likely to suffer catastrophic knee
injuries than their same-sport male counterparts1. There are many factors thought to contribute
to the higher injury rate including: The way girls land after jumping, over
development of the quadriceps as compared to the hamstring, and less lateral
stability through the legs. By
understanding and addressing these factors Canyon Performance coaches reduce
risk of injury by up to 50% in female athletes and increase sports performance
without increasing muscle size or creating “bulk.”
- Teaching proper landing
strategy: When landing after a jump, girls are less likely to properly
flex at the knee and hip2.
This poor landing strategy can lead to a tear to the Anterior
Cruciate Ligament. When working
with girls we start with small jumping motions and teach them how to land
with proper knee and hip flexion and increase to bigger and higher
motions. This technique can also
lead to increased vertical jump height.
As the body develops the habit of bending properly at the hips and
knees the athlete is better able to load and reload for a more explosive
jumping motion.
- By default girls tend to have
highly disproportionate quadriceps to hamstring strength ratios2. The quadriceps are so dominant they can
start to “overpower” the hamstring and gluteus maximus muscles making the
athlete more susceptible to knee and ankle injuries. We include hamstring and “Glute”
specific exercises in all of our strength programs for girls. These exercises strengthen and re-teach
the muscles to fire in proper sequence.
By doing this, over time, the strength ratios decrease and the
hamstrings and “glutes” start firing properly increasing lower body
explosive power.
- Canyon checks each female athlete for an “Anterior Pelvic Tilt.” Anterior Pelvic Tilt, or APT simply means the front of the pelvis sits lower than the back of the pelvis. An easy way to check is to observe the front of the waistband vs the back of the waistband when the athlete is standing tall. If the front of the waistband is lower than the back, there is APT. The APT can indicate tightness in the hips and weakness in the Core and “glute” muscles and decrease overall stability in the hip complex. Strengthening the Core and Glutes and stretching the front of the hips can help correct the tilt and may lead to less lower back and hip pain. This also has the added benefit of increasing the athletes overall balance and power.
- Female
athletes tend to have less lateral hip, knee and ankle stability3. During the single leg squat we can see
if there is excessive lateral hip translation (hip sticks out to the side)
or internal knee rotation, or valgus and a lack of hip and knee
stability. By doing corrective
exercises to strengthen the hips laterally we can help reduce the chance
for ACL injury and increase lower-limb power by achieving proper alignment.
- Finally, Canyon evaluates
all female athletes for ankle eversion and weak arches. By increasing stability in the ankle we
can help avoid ankle sprains and by strengthening the arch we can help
reduce the occurrences and severity of shin splints. Often times athletes are asked to play
through minor ankle sprains and shin splints. By helping to reduce the occurrences and
severity of these injuries we can keep athletes performing at a high level
through the duration of the season.
