Knee rolls refer to several distinct things, depending on the context. Let's explore the different meanings:
1. Knee Rolls as an Exercise
Knee rolls are a simple yet effective exercise used to improve spinal mobility and flexibility. As shown in several YouTube videos (example 1, example 2), the exercise involves lying on your back with knees bent and gently rolling your knees from side to side. This movement helps to gently stretch and mobilize the spine. This exercise is beneficial for those who sit for long periods, such as office workers (reference). A detailed description of the exercise can be found at Three Pillars of Fitness.
- How to perform:
- Lie on your back.
- Keep your knees bent and together, feet flat on the floor.
- Roll your knees to one side, then the other.
2. Knee Rolls in Hockey Equipment
In hockey, knee rolls refer to the padding on goalie pads designed to provide comfort and protection around the knees. The design and importance of knee rolls in goalie equipment are debated (reference), with some goalies preferring a "flat face" design for predictable rebounds. The presence or absence of knee rolls influences the goalie's leg position and shot reception (reference).
3. Knee Rolls in Saddle Construction
In the context of saddle making, knee rolls are the padded parts of a saddle designed to provide support and comfort for the rider's knees (reference, reference). These are distinct from knee blocks, which provide additional support and stability for the rider's leg position. Different materials are used to create the padding, such as neoprene foam.
4. Knee Rolls as a Rehabilitation Exercise
Knee rolls are also used in physical therapy and rehabilitation. David Grey Rehab mentions utilizing "90/90 Knee Rolls" as part of lower body rehabilitation exercises. This suggests a specific exercise protocol likely involving different knee positions and movements compared to the basic spinal mobility exercise.
