    Introduction Objectives of testing:

    To provide an objective profile of an athletes musculoskeletal fitness to engagein a sporting activity with minimum risk & injury, in addition maximummusculoskeletal performance.

    Negative information that provides or modifies performance must be considered:i.e. Disease, flu or unsolved injuries that continually cause niggles.

    Information is needed about physical deficiencies in strength, flexibility orendurance that may predispose an athlete to injury.

    Correction of these deficiencies will decrease the risks & provide the optimummusculoskeletal base for athlete performance.

    A reproducible record for sequent examinations, whether for the next season orafter injury is needed.

    To use the deviations from optimal levels: i.e. The various aspects of athletefitness to construct a sports specific programme to normalise any deficienciesdiscovered in the examination & testing.

    What is a Fitness Test A test designed to access the current state of a

    specific component of physical fitness

    Tests should be specific i.e. they should isolate a singlecomponent of fitness

    Tests should be valid & reliable reproduce resultsconsistently

    Tests should be sensitive: i.e.. It should be accurate enoughto detect change in fitness

    Tests should be objective - they should measure something

    Why Perform Fitness Testing? Strength & weaknesses (physical profiling)

    Baseline data for exercise prescription

    Feedback on athletes progress (improvement since last test)

    Assess training effectiveness

    Monitor health (overtraining)

    Motivation to train

    Establish normative data

    Talent ID

    Team / crew selection

    When Do We Perform Fitness Tests?

    Depends on your reason for performing the

    testing.

    To monitor fitness

    Tests should be performed regularly

    Rule of thumb - tests should be performed every 6 8 weeks

    During important training phases

    Testing can be performed more regularly

    Too often

    No time for change (can be demoralising)

    Too infrequently

    No feedback on progress (hard to access trainingeffectiveness)

    When Do We Perform Fitness Tests?

    Profiling athletes

    Tests should be performed when athletes are at peak physical

    fitness

    Exercise prescription

    Depends on the phase of the season, i.e. general preparation,competition or taper

    Talent ID

    Tests should be performed prior to team selection taking place

    Selecting Appropriate Tests To access the capabilities of an individual, or group

    of athletes The Relevance

    Tests should be sport specific & mimic actual sportingmovement

    Validity The tests must measure what they claim to measure

    Reliability Tests must be consistent and reproducible

    Acceptance The tests should have a sound scientific base & be accepted by

    peers

    Feasibility It must be possible to effectively complete the number of tests

    within the selected protocol given the availability of time,resources & facilities

    Validity

    An appropriate test should always measure what itclaims to measure - the test should bevalid.

    Can be determined by close examination of its

    content or by comparison with another acceptedmeasure of the same performance factor under

    scrutiny.

    Example: A test of aerobic capacity must be of sufficient length (in time)

    to ensure that the aerobic energy system is the predominate contributor to

    performance in that test.

    Alternatively:A high correlation between a test that directly measures

    aerobic capacity, such as the Shuttle Run test, & direct measurement of

    VO2 max obtained using a graded exercise test to exhaustion on a

    treadmill in a lab would establish the validity of the Shuttle Run as a

    measure of running endurance.

    The reliability of a quantitative measure is a criterionfor assessing its quality.

    Reliability refers to the consistencywith which aninstrument measure this attribute.

    An appropriate test should produce the sameresults on different testing occasions.

    Testers have to be diligent in ensuring the factorswithin both the subjects & the testing arena are heldconstant from one testing session to the next.

    To be reliable, the physical & psychological stateof the subject must be known & controlled .

    The testing environment & protocols must berepeated exactly the same.

    Reliability

    Recommended Tests & Testing Sequence

    Baseline testing should always be performed prior

    to the initiation of any programme.

    The testing is valuable not only for assessing the

    athletes starting point

    Also for helping to identify any obvious or latent

    strengths & weaknesses the athletes may have.

    The data gathered forms the nucleus around which

    the training programme is designed.

    Table 1 shows recommended tests & testing

    sequence along with the rationale for the tests.

    Recommended Tests & Testing Sequence NZ Squash

    Anthropometric Measures

    1. Body composition

    2. Standing Height

    3. Weight

    To evaluate lean body mass: goals are to decrease body fat and

    increase lean body mass.

    Aid in evaluation body composition and setting potential goals.

    Flexibility

    1. Sit & reach

    To identify flexibility deficits & improvement in the hamstring &

    lower back area.

    Aerobic Capacity

    1. 3 km run / or Multistage Shuttle run or

    treadmill

    To measure cardiovascular endurance.

    To measure peripheral muscular endurance.

    Repetitive Leg Power

    1. Standing, 4 hops plus jump

    To measure lower body power.

    Localised Muscular Endurance

    1. One minute sit-ups

    2. One minute press-ups

    To quantify abdominal endurance.

    To quantify upper body endurance.

    Speed & Agility

    1. 20 meter sprint

    2. T test * Both directions

    To measure forward acceleration and speed.

    To measure multiple direction & reactivity time.

    The Tests above are only a sampling of the tests that

    can be performed on a squash athlete

    Of primary importance, is the reliability & validity of the test & its

    administration.

    Table 1

    Testing Sequence

    The order in which the battery is performed

    should be carefully considered

    To ensure that the physical demands of one test do

    not compromise the results of subsequent

    evaluations

    Recovery intervals between tests should be

    planned to ensure that the risk of injury to athletes

    is kept to an absolute minimum

    One day: speed, strength, power before aerobic

    Two days: speed & aerobic day 1, strength, power onday 2

    Tests

    The following tests

    contain some of the

    most commonlyidentified physiological

    Dynamometer

    Kneeling overhead throw

    Muscular Endurance

    This type of test normally involves repetitive

    movements designed to stress a particularmuscle group or group of muscles

    Typically uses the athletes own body weight

    as the major source of resistance:

    Push ups

    Sit ups

    Pull ups (chins)

    Video Analysis for Skill

    Video analysis aims to provide feedback to coaches & athletes with agoal of increasing the desired performance.

    The athletes technique can be studied usually at slow speed or frameby frame.

    Qualitative (subjective assessment non numerical evaluation) &qualitative (measurement based provide kinematics & kinetics)feedback can provide a description of the movement in detail.

    Two dimensional or three dimensional analysis can be chosendepending on the type of movement patterns.

    Administration of the Test

    Success will be governed by preparation

    Ensure medical consent forms have been read,

    understood & signed where applicable

    Ensure pre-screening questionnaire has beenread, understood, followed & completed

    Provide for athlete privacy where necessary,i.e., during anthropometric testing

    Administration of the Test Ensure the athlete is prepared & dressed for the

    particular exercise

    Prepare athletes on test day by following all pre-org

    to ensure they are fully conversant with test

    procedures

    Motivate athletes: all athletes should be given thesame degree of motivation

    Ensure safety during the entire session, be prepared

    for the unexpected & remain alert

    Test Termination indications for

    Stopping a Test Key Points Onset of angina

    Failure of HR to increase as intensity increases

    Change to heart rhythm

    SBP either 260 mmHg, drops 10 mmHg OR fails

    to rise

    DBP 115 mmHg

    Severe fatigue, faintness, confusion, nausea, light-headedness, shortness of breath

    Subject asks to stop

    Failure of test equipment

    14/15

    Post Test Procedure

    Analyze test scores

    Complete as soon as possible after the testing

    Report as soon as possible after the testing period

    Necessary modifications to individual / team

    programmes

    File test scores

    Add to data bank / group norms

    Evaluation / Statistics The analysis of data collected provides the results of

    the testing.

    These results need to be evaluated & interpretedwhich is often a challenging task.

    The interpretation should take into consideration theaim of the testing, its theoretical underpinnings & theexisting body of related research knowledge & thelimitations of the adopted testing methods.

    The interpretive task involves consideration of thefollowing aspects: The credibility & accuracy of results

    The meaning of the results

    The importance of the results The extent that the results can be generalised

    The implications for practice, theory or research

    Summary

    Testing need not be time consuming & with the

    availability of portable equipment can easily be donein the field.

    To minimise disruption of training, reassessments

    should be scheduled to coincide with low intensity,

    low volume periods in the normal training cycle.

    Testing may be used to motivate athletes, to this

    end, test days should be scheduled as special

    events.

    This in no way precludes the use of test procedures

    as regular training drills.
