You’re En Pointe! Biomechanics and Ankle Injury Risk in Ballet Dancers
Dancing in pointe shoes raises the risk of injury for female ballerinas. Complex balletic movements require elevated muscular efforts and can put excessive stress loads on the ankle bones. Not many biomechanical studies focus on ballet, even as findings could contribute to decreased injury risk for dancers. A number of factors, such as ground reaction forces, ankle sway, and shoe flexibility can affect a dancer’s injury risk. But which factors contribute most?

When cracking your knuckles, one tends to hear a “pop” noise that is loud, sharp, and irritating to most. This noise can be addicting in the sense that it makes others want to crack their knuckles. The main questions that I focused my research on were “Does cracking your knuckles or joints cause potential health issues for your future?” and “ Why does cracking a joint such as your knuckles make a “pop” noise?”

Do you experience deep, sharp pain in your groin? Or a feeling of “catching” or “popping” in your hip joint as you go about your daily activities? Is your range of motion you once had now severely limited? If so, you could be experiencing symptoms of a hip acetabular labrum tear, an ever-increasing problem in society that fortunately, has effective treatments.

If you have seen the 1984 film “Karate Kid”, you know that the only way the protagonist Daniel LaRusso was able to defeat his nemesis Johnny Lawrence was with a “crane kick” to the chin powerful enough to knock him down allowing Daniel to clench the title of the Karate tournament.

Flight is a concept that has, until relatively recently in history, eluded humanity. However, birds have been successfully flying for approximately 130 million years, proving themselves to be a physical marvel of the natural world. And while our means of flight have historically been crude in design and performance, nature provides an elegant, efficient solution to get creatures off of the ground. Rüppell’s griffon vultures have been recorded flying as high as 37,000 ft, while some species of shorebirds have been recorded flying as far as from Alaska to New Zealand over eight days without stopping. But how exactly do birds seem to effortlessly overcome gravity so effectively? And perhaps more importantly, how might we apply these answers to improve manmade aircraft?

Every sport has a different “ideal” body type, which is largely dictated by the muscle groups it focuses on training. Swimmers prioritize developing the muscles in their shoulders and backs, which allows them to propel themselves through the water with their arms. On the other hand, runners prioritize the hamstrings and quads in their legs, which allows them to generate greater force when pushing off of the ground. So, what is the ideal body type for boxing? Strength is clearly important when punching an opponent, but is it even the most important factor in boxing performance? Should either upper- or lower-body strength be prioritized over the other?

Imagine yourself walking at a normal pace down the sidewalk. Maybe you are on your way to class. The sidewalk has a little bit of a tilt causing your left foot to be higher than the right as it plants on the ground. Imagine how your body may compensate after a few minutes of walking on this path. We have all walked on uneven ground and began to feel the effects with sore knees or hips. But what if you felt this same way all the time even on perfectly flat terrain? This is the reality for those with leg length discrepancies.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that, according to the Arthritis Foundation, affects 1.5 million people in the US. Women are 3 times more likely to develop RA and are usually diagnosed between ages 30 and 60, while men are rarely diagnosed before the age of 45.

Ankle injuries – either sprains or fractures – are one of the most common sports traumas plaguing the US today. Sprains are overextensions or tears in ligaments. Fractures, on the other hand, are broken bones.
