What is the Scope of practice?


In provinces where kinesiology is legislated, a kinesiologist's scope of practice is defined by law, this is not the case in other provinces thus the definition will differ from one province to another. We have, here, provided a scope of practice that encompasses what a kinesiologist may do in non-legislated provinces, as well as the legislated province (Ontario).

Kinesiologists treat asymptomatic (healthy) individuals and those experiencing chronic diseases (likely associated with morbidities). This brings on challenges when treating with exercises but also provides a greater benefit and impact on their quality of life. Despite treating chronic disease, Kinesiologists do not diagnose pathologies but rather collaborate with multidisciplinary care teams. They may work in the domains of sport, recreation and active living, and their wide scope of practice may include functional ability evaluations, rehabilitation, ergonomics, motor redundancy, neuroplasticity, adaptation through exercise, home/workplace health and safety, disability management, and research.

In Canada, Kinesiology is currently a legislated profession in some provinces, where licensed practitioners may use the title Registered Kinesiologist. In provinces without legislation, however, their titles may differ widely to reflect a particular area of focus: Certified personal trainer, Certified exercise physiologist, Exercise physiologist, Clinical exercise physiologist, Exercise specialist, Exercise Therapist, Cardiac rehabilitation professionals, Pulmonary rehabilitation professionals, Ergonomist, Exercise Scientist, Usability Designer, Exercise professional, Sport and exercise scientist, Clinical Kinesiologist.

In most countries, kinesiology refers to an area of study and is not associated with a professional designation except in Ontario where kinesiolgists have a professional designation (Registered Kinesiologist or RKin) associated with movement, performance, fitness and function, rehabilitation, prevention and management of chronic diseases, sport, recreation and work. In other provinces, the professionals to practice Kinesiology are refered to as Kinesiologists. All based on the following principles:


Adaptation through Exercise

Adaptation through exercise is a key principle of kinesiology that relates to improved fitness in athletes as well as health and wellness in clinical populations. Exercise is a simple and established intervention for many movement disorders and musculoskeletal conditions due to the neuroplasticity of the brain. Therapeutic exercise has been shown to improve neuromotor control and motor capabilities in both normal and pathological populations.

There are many different types of exercise interventions that can be applied to kinesiology to athletic, normal, and clinical populations. Aerobic exercise interventions can help to improve cardiovascular endurance. Anaerobic strength training can help increase muscular strength, power, and lean body mass. Decreased risk of falls and increased neuromuscular control can be attributed to balance intervention programs. Flexibility programs can increase functional range of motion and reduce the risk of injury.

Taken collectively, exercise programs cna reduce symptoms of depression and risk of cardiovascular and metabolic diseases such as diabetes. Additionally, they can help improve quality of life, sleeping habits, immune system function, and body composition.

The study of physiologic responses to physical exercise and their therapeutic applications is known as exercise physiology, which is a major research focus for kinesiologists.



Neuroplasticity is also a key scientific principle used in kinesiology to describe how movement and changes in the brain are related. The human brain adapts and acquires new motor skills based on this principle, which includes both adaptive and maladaptive brain changes.

Recent empirical evidence indicates the significant impact of physical activity on brain function. For example, greater amounts of physical activity are associated with enhanced cognitive function in older persons. The effects of physical activity can be distributed throughout the entire brain, such as higher gray matter density and white matter integrity after exercise, and/or specific brain areas such as greater activation in prefrontal cortex and hippocampus. Neuroplasticity is also the underlying mechanism of skill acquisition. For example, after long-term training, pianists showed greater gray matter density in sensorimotor cortex and white matter integrity in the internal capsule compared to non-musicians.

Maladaptive plasticity is defined as the neuroplasticity with negative effects or detrimental consequences in behaviour. Movement abnormalities may occur among individuals with and without brain injuries due to abnormal remodeling in the central nervous system (CNS). Learned non-use is an example commonly seen among patients with brain damage, such as stroke. Patients with stroke learned to suppress paretic limb movement after unsuccessful experience in paretic hand use. This may cause decreased neuronal activation at adjacent areas of the infarcted motor cortex.

There are many types of therapies that kinesiologists might explore to overcome maladaptive plasticity in clinic and research, such as constraint-induced movement therapy (CIMT), body weight support treadmill training (BWSTT), and virtual reality therapy. These interventions have been shown to enhance motor function in paretic limbs and stimulate cortical reorganization in patients with brain damage.


Motor Redundancy

Motor redundancy is a widely-used concept in kinesiology and motor control which states that for any task the human body can perform, there are effectively an unlimited number of ways the nervous system could achieve that task. This redundancy appears at multiple levels in the chain of motor execution.

Kinematic redundancy means that for a desired location of the endpoint (e.g. the hand or finger) there are many configurations of the joints that would produce the same endpoint location in space. Muscule redundancy means that the same net joint torque could be generated by many different relative contributions of individual muscles.

The concept of motor redundancy is explored in numerous studies usually with the goal of describing the relative contribution of a set of motor elements (e.g. muscles) in various human movements, and how these contributions can be predicted from a comprehensive theory. Two distinct (but not incompatible) theories have emerged for how the nervous system coordinates redundant elements: simplification and optimization. In the simplification theory, complex movements and muscle actions are constructed from simpler ones, often known as primitives or synergies, resulting in a simpler system for the brain to control. In optimization theory, motor actions arise from the minimization of control parameter, such as the energetic cost of movement or errors in movement performance.
