A few studies have shown that the parallel squat is king for maximizing work and overloading on the muscles . High reps with low to moderate weight gives exercisers the least effective way to overload the lower body muscles. The deep squat can contribute to tight knee joints / kneecap pressure . With this in mind , would you put deep squats in your personal leg workout ?
I think it is so very important that fitness professionals understand the biomechanics of the knee joint as well as the arthrokinematics of the knee joint. How the femur rotates on the tibia and how the tibia rotates on the femur and what joints and joint structures are involved in a deep squat.
I believe if more fitness professionals were aware of the above, they would not include deep squat in their programs unless it specific to their sport. If it is not, it just not worth the risk of damage to connective tissue.
Thanks for your question.
Depends on the client and the goals. Personally I love to powerlift, so I squat, and I squat low.
I agree with Bryant, in that as long as most trainees progress slowly and have correct form, there should be no knee issues. In fact, if you look at the mechanics of the movement, partial squats have a tendency to create muscle imbalances, as they are quad-dominant. This can result in unequal pressure being placed on the knee ligaments.
That being said, there ARE some people who are going to have mobility issues, particularly those who have no exercise experience or previous injuries. I think squats should be part of a progression and should be worked into, much like Karin has stated, as some clients will not be able to effectively handle their own bodyweight. For some of us, squats come easy, but the squat is actually a fairly complex movement that also requires a great degree of balance and coordination.
Good training is key here, as there are a lot of things you need to pay attention to when you are having a client squat. Generally, I have healthy clients go as low as they can before they lose ability to maintain lumbar curve (this is not the only thing I am looking for, but for the sake of brevity…). My end goal is to have them go low enough so that the hip crease is below the knee, however, there will be some people who simply cannot go this low without a LOT of mobility work…and some can’t go that low at all.
As for the leg press, I am not a big fan of the movement, which I believe is, at best, an assistance movement. The positioning puts people in a position where they can handle an unusually high amount of weight, but also can place the back in a compromising position, particularly if the weight is high enough to cause the client to lift his/her hips off of the pad. Not good.
I tend to emphasize the squat, for the functional aspect of it and its ability to improve quality of life.
Personally I don’t do deep squats and I’m not sure what you mean by tight knee joints?
There are many gyms and programs using deep squats routinely regardless of the damage that can potentially occur by not using proper progression.
Again, we are not a regulated industry
For the majority of people- simple leg press or parallel squats will be more than adequate.
For the minority who want to play sports or really challenge themselves? Deep squats are a must.
Ignore those who say the deep squats are bad for the knees- completely not true as long as the person progresses safely and at a good pace. Most injuries are results from people training improperly.
