Document Summary
Flexibility is the range of motion (rom) around a joint. Stretching is a component of exercise programs. The 120-minute run test is also known as the copper test . Dr. cooper suggests that, by the time you are 50 years old, 50% of your training should be resistance training. Benefits of stretching include: joint health, reduction of low-back pain and injuries, reduction of doms, pain relief, athletic performance, improve posture, relaxation. Rom must be adequate for daily activities. Some people have a greater rom because of the way their bones are shaped. Different joint structures allow different ranges of motion. Normal activity and exercises through full rom reduce the likelihood of a muscle shortening, and a well designed stretching program can actually lengthen the muscles. With a stretching program, sarcomeres are laid down in series, increasing muscle length. The nervous system plays a role in what range of motion you can achieve by regulating muscle contractions.
