The parts of the body that come together can form a sequence of movements. Understanding how the body works and the sequence of movements is essential for effective exercise.
The concept of a motion chain dates back to 1875, when a mechanical engineer named Franz Reuleaux suggested that when a series of overlapping segments were joined through joints, a system would be created that would allow the movement of the body. one joint, which can affect the motion of another joint during inter-motion. Dr. Arthur Steindler applied this theory in 1955, including the analysis of human motion. Steindler argues that parts such as arms and legs are viewed as rigidly overlapping segments. From there, he defined the dynamic series as “the combination of several joints arranged sequentially to form a complex unit of motion”. Movements occurring in segments manifest in two basic forms, opening and closing.
Open motion sequence
The open motion chain is defined as a combination of fully arranged joints in which the end segment can move freely. In an open sequence of motion, the extremities of the extremities or the end of the chain furthest from the body can move freely and are not fixed to anything. Here are some examples of open sequence exercises:
- Sitting posture stretching legs;
- Dumbbell exercises for hamstrings;
- Exercises to push chest muscles;
- Dumbbell curl exercise for forearms;
- Exercises for the lats muscle group.
Closed motion sequence
Chain-of-motion exercises serve as a condition or environment in which the distal extremity is externally immobilized and restricted in motion. In a closed motion, the terminal portion of the limb is immobilized, increasing joint compression and subsequently increasing joint stability. The following are closed sequence exercises that are considered more practical than open sequence exercises.
- Exercises to carry weights and stand, sit up and down;
- Wall slide exercises;
- Exercises to build butt muscles;
- Elliptical Exercises – Running on a treadmill;
- Stair stepper exercise – walking up and down stairs;
- Exercises on the Versa Climber machine;
- Push up chest and arm muscles.
Understanding how the body and all its segments work together is essential in developing effective exercise programs. Furthermore, knowing the difference between open and closed motion sequences can help you choose the right exercise based on your individual needs.
