Explanatory notes
1
This unit standard is intended as a basic introduction to the principles of
biomechanics for sports coaches, instructors or trainers. Competency in this unit
standard will provide learners with additional tools to help improve sporting
performance and reduce potential injury to participants.
2
In the context of this unit standard, basic biomechanical principles are principles that
explain the force-motion relationship, ie, what makes a body move and the results of
that movement.
Outcomes and evidence requirements
Outcome 1
Explain how basic biomechanical principles apply to a selected sport.
Evidence requirements
1.1
Explanation of basic biomechanical principles examines the relationship
between balance and stability as they apply to the specified sport.
Range
relationship includes – centre of gravity, base of support.
1.2
Explanation of Newton’s laws examines their application to the specified sport.
1.3
Explanation of momentum examines its application to the specified sport.
Range
momentum includes – mass, distribution of mass, moment of
inertia.

1.4
21646 version 2
Page 2 of 3
Explanation of the flight path of a projectile examines its influencing factors in
the specified sport, where projectiles are relevant.
Range
influencing factors may include but are not limited to – speed,
height and angle of release, spin, gravity, air resistance, amount of
force at impact.
1.5
Explanation of force generation by the body in the specified sport examines the
relationship with force summation and the timing of body parts.
1.6
Explanation of levers in the body examines factors affecting them.
Range
factors include – length of the lever, angle of the joint and strength
of the muscles involved, use of implements.
Outcome 2
Observe and examine the performance of a complex movement sequence from the
selected sport.
Range
complex movement sequences may include but are not limited to – tennis
serve, golf swing, long jump, discus throw, gymnastics skill, aquatics skill.
Evidence requirements
2.1
Description of the complex movement sequence identifies the phases of
execution.
Range
2.2
phases of execution include but are not limited to – preparation
phase, action phase, post-action phase.
Key biomechanical principles involved in each phase of the performance of the
complex movement sequence are identified through observation.
Range
biomechanical principles may include but are not limited to –
centre of gravity, base of support, Newton’s laws, momentum,
projectile motion, force summation, timing of body parts;
positioning for observation may include but is not limited to – from
front, rear, side, above performer.
2.3
Examination of the complex movement sequence identifies common errors in
the performance of the sequence.
2.4
Examination of the complex movement sequence identifies possible causes of
the common errors and solutions for the faults in terms of the biomechanical
principles involved.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMRs). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
