Observing & Analysing Movement The physical activities in which we The physical activities in which we

participate are made up of basic participate are made up of basic MOVEMENT PATTERNS such as running, MOVEMENT PATTERNS such as running, stopping, throwing and striking.stopping, throwing and striking.

These movement patterns are adapted to These movement patterns are adapted to suit the particular activity in which they suit the particular activity in which they are being applied.are being applied.

Eg. Striking – softball, cricket, tennis etcEg. Striking – softball, cricket, tennis etc When this adaptation occurs the basic When this adaptation occurs the basic

movement pattern becomes known as a movement pattern becomes known as a SKILL.SKILL.

When the same skill is performed in a When the same skill is performed in a particular way, it is known as a particular way, it is known as a TECHNIQUETECHNIQUE

Eg using a top-spin or slice on the Eg using a top-spin or slice on the backhand in tennisbackhand in tennis

Biomechanics can play a key role in the Biomechanics can play a key role in the analysis of movement patterns, skills and analysis of movement patterns, skills and techniques as we strive to enhance our techniques as we strive to enhance our performance. How????performance. How????

By providing a systematic strategy and By providing a systematic strategy and principles that can be applied.principles that can be applied.

Descriptive InformationDescriptive InformationEnables the analysis of skills such as:Enables the analysis of skills such as: Correct sequencing of movementCorrect sequencing of movement Release position of the ballRelease position of the ball Racquet trajectory needed to for backspinRacquet trajectory needed to for backspin

This type of info is useful to the coach for This type of info is useful to the coach for providing +ve feedback to the performer.providing +ve feedback to the performer.

It enables the coach to make meaningful It enables the coach to make meaningful statements eg “Good shot, you followed statements eg “Good shot, you followed through with your fingers to the basket through with your fingers to the basket that time.that time.

Causal InformationCausal Information Cause-effect info enables the correction of Cause-effect info enables the correction of

the cause of ineffective movement, rather the cause of ineffective movement, rather than simply addressing the results.than simply addressing the results.

Often, too much time is spent correcting Often, too much time is spent correcting the symptom rather than the cause of the the symptom rather than the cause of the problem.problem.

Analysing Basic Movement PatternsAnalysing Basic Movement Patterns The analysis of technique can be simplified to The analysis of technique can be simplified to

some extent, if we remember that movement some extent, if we remember that movement patterns apply across a wide range of activities, patterns apply across a wide range of activities, and that biomechanical principles often apply to and that biomechanical principles often apply to more than one movement pattern.more than one movement pattern.

For eg. The principle of summation of momentum For eg. The principle of summation of momentum applies to both throwing and strikingapplies to both throwing and striking
