Biomechanics in Physical Biomechanics in Physical Education Sports and ResearchEducation Sports and Research

• The principles of mechanics are directly applied both to the movements of the human body and to the sports implements he handles.

• Due to the interest in the mechanical analysis of man in motion the new area in physical education emerged as Biomechanics of Sports.

Cont.Cont.

• The branch of science, biomechanics is a broad area and the biomechanics of sports is only one of the area.

• The same principles which is applied to biomechanics is also applied to sports biomechanics.

Other Area of Applied Other Area of Applied BiomechanicsBiomechanics

• Industrial Engineering

• Ergonomics

• Physical Rehabilitation

• Biomedical Physics

• Aerospace Science

Status of Sports BiomechanicsStatus of Sports Biomechanics

• Out of the field of the other applied biomechanics, the biomechanics of sports is least advanced.

• But now a days use of advanced technology in the form of computer and electronic recording device has created the scope of research and further study in the field of sports biomechanics.

Importance of Biomechanics for Importance of Biomechanics for Sports PerformanceSports Performance

• It helps in analyzing the sports performance. Data of performance is collected by different biomechanical techniques as cinematography, myography and analyzed.

Importance Cont.Importance Cont.

• It helps in selection and adoption of techniques. It help for deciding the technique on the basis of human structure and its possible movement for the best result in sports.

Importance Cont.Importance Cont.

• It helps in discovering the technique for the use of new equipments.

• It gives technical knowledge of technical mistakes.

• It helps in differenciating competition and training exercises.

• Physical ability can be developed with its help.

Importance Cont.Importance Cont.

• It helps in generalising the solution of biomechanical problems.

Basic FundamentalBasic Fundamental

• The skill developed from childhood through the incoming years to perform the daily life activities such as walking, running, jumping, throwing, catching, carrying etc.

Fundamental of Games and Sports Fundamental of Games and Sports

• The skills of different games and sports which actually constitute the total play in a given sports and games.

• Like Forward drive in cricket

• Lofted kick in football

• Fosbury flop in high jump

• Spiking in volleyball

MovementMovement

• Movement means a change involving location and position of an object.

• Example –

• The whole body is displaced in case of walking or running.

• Or any change in posture is identified as movement i.e. flexion of arm, extension of arm.

AnalysisAnalysis

• Analysis –

• Analysis means splitting up a given movement into its component parts i.e. into its basic parts

Movement AnalysisMovement Analysis

• Kinesiological Analysis

• Mechanical Analysis

• Biomechanical Analysis

Kinesiological AnalysisKinesiological Analysis

• A kinesiological analysis of a motor skill consist of breaking the skill into its constituent elements for determining the nature of each movement and of identifying the appropriate mechanical and anatomical principles.

Kinesiological AnalysisKinesiological Analysis attempts to find specific answers to attempts to find specific answers to

the following questionsthe following questions

• What joint are involved and what are theit exact movements in the motor skills.

• Are any of the joints used to the limit of their range of motion.

• What muscles are responsible for the joint action and what is the nature of their contraction

specific answers to the following specific answers to the following questions Cont.questions Cont.

• Do any one of the muscle group exert maximal or near maximal effort.

• What anatomical and mechanical principles contributes to maximal efficiency and accuracy in the performance of motor skill.

Mechanical AnalysisMechanical Analysis

• Mechanical analysis of an activity involves the identification of law and principles which help to explain the most appropriate form for the execution of the activity and to identify the mechanical reason for success or failure.

Biomechanical AnalysisBiomechanical Analysis

• Biomechanical analysis is the process of identifying both the internal as well as external forces coming into play during the performance and the effect produced by these forces on that performance.
