Back squats are a common exercise used by athletes and the general population. It is a great multi-joint exercise that requires all parts of the lower body moving optimally. The main muscles used while squatting are in the hip and knee joints, for example the quadriceps and gluteal muscles. These muscles are responsible for 80-90% of the movement. There are numerous training accessories that can be used by individuals to improve their training or prevent injury, such as knee wraps and neoprene knee sleeves.
Knee wraps are an accessory mainly used for heavy back squats to improve knee stability, performance, and confidence. Previous research has found that knee wraps can increase power output due to elastic energy stored while descending. This elastic energy storage is then released during the ascent phase resulting in greater 1-repetition maximums (1RM). Research has also shown that the use of knee wraps can alter the muscle activation in the legs.
One study compared the vastus lateralis (muscle on the front outside of your thigh) and the gluteus maximus (buttocks) while wearing and not wearing knee wraps. They found that while wearing knee wraps, muscle activation of the vastus lateralis increased but the gluteus maximus decreased while squatting at 90% 1RM. The researchers also found that the knee wraps require precise wrapping techniques and can potentially occlude the knee joint if done improperly. Due to the change in muscle activation as well as potential for altering the biomechanics of the hip and knee, there is a possibility of negatively impacting the joint stability while weight training.
Neoprene knee sleeves are another common weightlifting accessory which are compression-style garments. Unfortunately there is not a lot of research on the advantages or disadvantages of wearing this accessory. Despite the support of research, companies continue to market knee sleeves as a means of improving knee joint stability, increasing the ability to lift more weight, perform more repetitions, or increase training intensity.
Research has discovered that people with knee osteoarthritis demonstrated improved joint position sense, pain, stiffness, and function while wearing knee sleeves compared to not wearing them while walking. Another article found that people without knee osteoarthritis while wearing knee sleeves and training at a low-load improved the control of their tibia (lower leg bone).
Only one study compared wearing knee sleeves, competitive knee wraps, training knee wraps, and nothing on the knees during submaximal squats. The researchers found that knee sleeves did not improve performance compared to not wearing them. They also found that comparing no support to the other knee wraps showed a lack of a statistical meaningful difference too.
A study by Bennett et al. found no significant differences during maximal resistance in 1RM, peak vertical velocity, knee joint angles at maximal depth, or muscle activation. The only significant difference was the increased activation of the gluteus maximus while not wearing knee sleeves from full depth to standing. Based on these findings, knee sleeves do not provide beneficial effects to weightlifting and do not appear to improve biomechanics during weighted back squats.
