Posted by 051118 Sport and lifestyle activity-range of motion exercising
Your joints and muscles are meant to function within standardized degrees of movement, commonly referred to as the range of motion (ROM). The stronger you are within these ranges, the better protected you will be in preventing injuries from occurring. Therefore when doing your exercise routine keep in mind the following two guidelines:
- You gain the most strength within the range of motion (ROM) at which you exercise.
- The smaller the range of motion you in the joint, the less will be the carry over strength throughout the rest of the movement.
The basis of every quality strength training or fitness program relies, in part, on these two premises. As an example, let’s look at the squat while explaining these principles.
Many lifters do short range squats, known as high squats, in the gym. They get into a machine or in rare cases under a bar and drop down a few inches and call it good. In many instances this isn’t even to a parallel position, let alone below parallel where they should be before starting back up again. Depending on the load of the bar or on the machine, strength may be increased within this small range of motion but its unlikely this will happen.
This range of movement is too little and does not support normal living activities such as sitting down in a chair and then getting back up. If the strength is not developed within a range that is vital to living an active lifestyle then it is not useful. This group of fitness enthusiasts would be better served by going deeper in their squats, thereby getting a transfer of useable strength into their daily lives. This naturally leads in to the second principle.
An individual or strength athlete will become stronger when training the full range of motion. This expands the strength curve and transfers more useable muscle activity across greater degrees of the joint angle. Greater degree angles of strength protect the joint from injury, especially at the far ranges of motion.
The take home message is don’t cut yourself short with limited range of motion exercises.
