What exactly is Biomechanics??
Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to gain a greater understanding of performance in athletic events through modeling, simulation and measurement. 
It is also necessary to have a good understanding of the application of physics to sport, as physical principles such as motion, resistance, momentum and friction play a part in most sporting events. Biomechanics is a diverse interdisciplinary field, with branches in Zoology, Botany, Physical Anthropology, Orthopedics, Bio-engineering and Human Performance. 


What is the general role of biomechanics and how does it relate to sports?
The general role of biomechanics is to understand the mechanical cause-effect relationships that determine the motions of living organisms.

In relation to sport, biomechanics contributes to the description, explanation, and prediction of the mechanical aspects of human exercise, sport and play.

Different jobs in Biomechanics
It is generally believed that jobs in biomechanics are limited to highly competitive research positions at universities or government organizations. However, the courses taken in an undergraduate level biomechanical or related degree program prepare students to work in jobs like sports trainer, fitness journalist and product development manager for biomechanical innovations. More people in society are trying to reach fitness goals and adopt anti-aging strategies, which is why professionally educated sports trainers and the writers who promote their talents are in great demand. Also, those who help develop human machine interface (HMI) products like ergonomic devices that help prevent and alleviate stress on sensitive body parts also find positions with innovative companies. Students who continue their education and receive an advanced or doctoral degree in biomechanics or a related discipline have broader employment options that include positions like sports physiologist, biomechanical researcher and physical therapist.
