I understand this is generally what the literature shows and has become convention to do THA for active older adults and hemi's for less active adults (at least at my institution), but I don't really understand the mechanism as to why this is

Hello, does anyone has this and willing to share? Thanks
If you don’t know biomech please don’t message me. I will need to see vouchers and have you complete some sample questions!
I really want to do Biomechanics, but I only take Life Sciences/ Biology. If I did a Biological Sciences Degree, would that be enough for me to transfer into a Biomechanics degree?
I read a summary about sensory hairs and gelatinous mass and lime crystals in canals in your ear, but it still left me semi-confused. ELI5 how do our ears play a role in knowing our physical orientation?
Has anyone had any experience with a physio or chiropractor or whoever can help me with my fucked up biomechanics. The entire left side of my body from my ankle to my neck/trap is fucked up. I can’t get as good of a contraction at the gym and I can’t seem to figure out what the problem is. When I do lay pull downs my mid back spasms and I look like I’m having a seizure at the gym. I’ve had fucked up ankles since being a young dumb kid and having continued playing soccer having torn ligaments on both ankles. Cracking ankles, cracking knees, imbalanced hips during squats, herniated disc, inability to squeeze left lats, shortened bicep, constantly tight trap. It’s just all fucked up. I don’t know where to start. I’m tired of doctors taking MRIs and telling me my shoulder is fine and I have a herniated disc. My shoulder sounds like everything inside it is being crushed if I do an overhead raise without any weight in my hand. Unfortunately they don’t do MRIs while you are moving but instead make you stand static and tell you everything is okay.
Sorry for the huge ass rant but it’s frustrating. I’m not okay. Shit hurts and feels like it’s going to break. I’m 4 months into the gym and I don’t know where to start. Any help is appreciated.
I am looking to get a job as a research assistant with my work-study next semester and I am really interested in an Electrical Engineering professor's research about prosthesis and AI. That professor focuses way more on the electrical and computer engineering side of prosthetics, though, and I am more interested in the Biomechanics portion of Bioengineering.
Would it look bad on a resume to have research that isn't one-to-one with my concentration? I am only a Freshman FYI, so maybe for an undergrad resume it won't look too bad
Hi everyone! I had my first mechanics class this semester, and the teacher makes us train on this biomechanics exercise :
- What is the value of the force exerted by the arm required to do a push-up?
- Why does the exercise become easier if the man uses a bench to support the hands?
- How does the effort change if the man is doing this exercise on his knees?
A push up is the whole going down + up process. We are free to use the data (mass, height) we want. I do not know how to approach this problem and could just draw a diagram with the weight and the two reactions at the feet and hands. Could anyone enlighten me? I feel like I am struggling with all the reasoning and make it more complicated than it is! Thank you very much to those helping me! :)
I'm still unsure about what i want to do after i graduate. I will be graduating with a sports science degree. I really want to take a master's degree but i'm not sure what are the career options after.
Only looking for those who are good in mechanics, preferably those who major in biomedical engineering.
Will test you

When people think of “ankle mobility” they often are referring to dorsiflexion, or the ability for the shin to translate forward over the foot.
However, ankle mobility is so much more than that, and it is intimately tied to how we move in many forms of locomtion & force production.
In this post, I’m going to cover:
- The biomechanics of the foot in movement
- What limits ankle mobility
- Strategies for improving ankle mobility
##Biomechanics of the Foot in Human Movement
When we walk, run, jump, cut, or do just about anything dynamic, we need the foot to interact with the ground to create movement up the chain into our hips (pelvis), and subsequently, our upper body is going to respond to that lower body movement.
Let’s break down foot movement in normal gait mechanics. When we strike the ground with our heel, the foot is biased towards supination, which requires external rotation up the chain into our leg and pelvis.
Upon loading all of our weight onto the foot, we are quickly moving into internal rotation (from a position of relative external rotation) of the pelvis and leg, meaning the foot has to pronate (the arch drops).
Now, here’s where things get interesting. The foot has to be able to pronate for the shin to translate over the foot (dorsiflexion). This means that you cannot sperate pronation from dorsiflexion. These are two inherently coupled joint actions.
The pronation allows the foot to drop which allows for the muscles on the bottom-side of the foot to stretch out. The overwhelming majority of muscles that attach on the bottom of the foot are supination muscles, meaning that the stretch on those muscles sets us up to “re-spring” the arch upon push-off (late-stance). This is referred to as the Windlass Mechanism.
Now we have a situation where the ankle is biased towards re-supination, meaning external rotation up the chain.
Proper pronation will help set up a proper push-off (force production) via proper internal rotation.
In terms of weightroom exercises, we need ankle mobility when internal rotation is needed in the body. This occurs in mid-stance in gait, and because internal rotation = force production, we also need it during the sticking point (hardest part) of a squat or d

Anyone has them? Thanks
