Kinesiology is the study of human movement in the physical sciences. The study of the human body as an organism for performing work is rooted in three major areas of study, namely mechanics, anatomy and physiology. The following aspects are highlighted: Biomechanics: description of human motion, condition of linear motion, condition of rotary motion, centre of gravity and stability; Musculoskeletal anatomy: the upper extremities (shoulders and elbows), the lower extremities (hips, knees and ankles), the spinal column and thorax; Neuromuscular physiology (skills): standing posture, kinesiology of fitness and exercise, throwing, striking and kicking skills; Movement on solid surfaces; Movement in an aquatic environment; Movement when suspended and free of support. The accumulated knowledge of these fields forms the foundation of the study of human movement.
