components of fitness this course is concentrating on.

Health Related Components of Fitness

Cardiovascular Endurance: The ability of the heart and lungs to supply oxygen to the working muscles during continuous exerciseLocal Muscular Endurance: The ability of a muscle or a group of muscles to sustain exercise over a period of time without fatigue setting in

Strength: The ability to exert force in a single effortFlexibility: The ability to move or stretch through a large range of motion around a joint (ROM)Body Composition: Ratio of muscle and bone weight to fat weight

Principles of Training

Progression Specificity Reversibility Placement Individual

Differences Adaptation

Overload Frequency: How often?

Intensity: How hard?Time: How long?Type: Circuits, aerobics, weights etc

Principles of Training

• Overload: In order to improve your fitness levels, you must work the particular component against a load greater than normal.

• Progression: As a person becomes fitter, a higher intensity of exercise is needed to create an overload.

• Specificity: The result of the type of exercise performed is specific both to the muscle groups being used and to the energy system involved.

• Reversibility: Training effects gained are reversible if workouts stop.

• Placement: The scheduling of the training, both within a week/month etc. and within each session.

• Individual Differences: Each person will have different capabilities and will adapt in a different manner to an exercise programme. There is no ‘one for all’ programme.

• Adaptation: The way the body changes as a result of training, e.g. muscles may become stronger.

Principles of Training

Cardiovascular Endurance: The FITT Principles

Frequency: 3 to 5 times per week Intensity: 60% to 85% MHR Time: 20 min (minimum) Type: Aerobic: running, cycling, swimming etc.

Flexibility: The FITT Principles

Frequency: 3 times per week upwards Intensity: To the point of tension Time: 15 to 30 secs Type: Stretching: passive, static, active, active

assisted, PNF.

Muscular Endurance: The FITT Principles

Frequency : 3 to 5 times per week Intensity: 60% to 70% 1 RM Time: As long as it takes to do 15 to 30 reps Type: Weights, circuits etc.

Strength: The FITT Principles

Frequency: 3 to 4 times per week Intensity: 70% to 90% 1 RM Time: As long as it takes to do between 2 and

10 reps Type: Resistance training (weights )

Body Composition:The FITT Principles

Frequency: 3 to 5 times per week Intensity: 55-65% MHR Time: 20 to 60 mins aerobic activity (continuous

or intermittent) Type: Aerobic (primarily), LME, any activity that

uses large muscle groups

What is Fitness Assessment?

Fitness Assessment is a vital part of the total professional service offered to clients and is the method used to evaluate the health fitness status of the client.

Uses and Purpose of

Fitness Assessment Individual diagnosis Exercise prescription Achievement of individual

goals Motivation Measure improvements Educational purposes

Programme evaluation Protect against

litigation Instructor credibility Lines of

communication - GP

Stages of Health/Fitness Assessment

Stage 1: Screening: Health history Health behaviours Risk factors Informed consent Stage 2: Physical measures: Resting heart rate Resting blood pressure Height Weight Cholesterol Stage 3: Fitness testing: Core tests

WHY SCREEN?1. Identify persons who need

special attention2. Identify persons who should

exercise in a special way3. Identify persons who should not

be exercising at all

4. Helps HFI gain knowledge of physical ability of clients

5. Enhances credibility of HFI as professional

6. Can help protect HFI - legal problems

7. Helps to open lines of communication between GP and HFI

Health/Fitness Assessment

Cardiovascular Endurance

• The ability of the heart and lungs to supply oxygen to the working muscles during continuous exercise

Oxygen Uptake

Amount of oxygen taken up and used by the body.

Reflects total amount of work being done by the body.

During strenuous exercise, VO2 max increases linearly with increases in the intensity of exercise.

Approaching exhaustion, VO2 reaches a max above which it will not increase further: VO2 max - largest amount of oxygen body can use during maximal exercise

Maximum Oxygen Uptake (VO2 max)

VO2 max: the greatest rate at which oxygen can be consumed during exercise at sea level!

V: the volume of oxygen used per minute

O2:the oxygen

max: maximal exercise conditions

VO2 Max

VO2 max is the highest rate of oxygen consumption that a person is capable of using during maximal exercise

Referred to as maximal aerobic power or maximal oxygen uptake

Usually expressed in ml/kg/min

Best measured in lab during maximal exercise test in which the oxygen consumed is measured by a computerised metabolic chart

VO2 Max

OHP 8

Maximum Oxygen Uptake (VO2)

VO2 max is used as the most accurate measure of a person’s aerobic power or fitness

A higher VO2 maximum reflects an increased ability of:

heart to pump blood lungs to ventilate large volumes of air muscles to take up oxygen and remove carbon

dioxide

Laboratory measurement of VO2 max is: expensive time consuming requires highly trained personnel not practical for mass testing situations

Therefore, various tests have been developed as substitutes.

Steady State

Where oxygen supply equals demand

Lactate Threshold

……. is the highest exercise intensity or level of oxygen uptake beyond which there is an irregular rise in lactic acid production.

Types of Tests

Maximal: Begin at low intensity and gradually bring the subject to volitional exhaustion. Normally provides a more accurate estimation of VO2 max than sub-maximal tests, but they induce greater cardiovascular stress.

Sub-maximal: Based on the assumption that heart rate is a linear function of VO2 max. Induces less cardiovascular stress.

Types of Tests

Field tests: Suitable for use with large numbers. Performed outside the laboratory, are practical, inexpensive, less time-consuming and easy to administer.

Stop the test if ...

subject requests to stop dizziness, mental confusion, staggering or

unsteadiness angina - chest pain Nausea difficult or laboured breathing (dyspnea) pallor (paleness)

Stop the test if ...

cyanosis severe fatigue (facial distress) no steady state heart rate HR in excess of 85% maximum HR malfunction of equipment

CV Tests

Walk test Shuttle run test Bike test Treadmill tests Step tests

Testing for Flexibility

Flexibility can be measured by means of the following tests:

Sit and Reach Straight Leg Raise Shoulder Elevation Back Extension

Sit and Reach(Low back & Hamstrings) Specific warm up Remove shoes and place feet at the special

box where 23cms is at the level of the feet Keep knees straight and place one hand on

top of the other Bend forward at the trunk, keeping the

knees straight and reach forward as far as possible.

Three attempts and record the best. Check table for standards.

Straight Leg Raise (Hamstrings)

Lie flat on a table making sure that the low back is flat

Stabilise the leg that is not being lifted Lift one leg with knee straight and evaluate

the angle of the hip. Check Table for standards

Shoulder Elevation

Lie on tummy, keeping arms straight and shoulder width apart, raise a stick as high as possible while keeping the chin on the floor and wrists and elbows straight

Measure in inches from the bottom of the stick to the floor(best of three attempts)

Multiply result by 100 and divide by the arm length in inches(Hold stick in both hands and measure from the shoulder to the upper surface of the stick)

Back Extension (Extension of the spine)

Lie prone on the floor Place hands under shoulders.Keep hips

down all the time. Raise the chest slowly using the arms not

the back. Measure in cm from the suprasternal

notch to the floor. Check the table for standards.

Muscular Endurance

The ability of a muscle or group of muscles to exert a sub-maximal force repeatedly or continuously over time

Muscular Endurance Tests

New crunch curl-up Push up Modified push up Bench press

New Crunch Curl

The subject lies supine. Knees bent at 90. Finger tips touching strips of

masking tape placed perpendicular to the body. A second strip of tape is placed parallel to the

strip, 8 cm apart. A metronome is set at 40 beats per minute (3

secs per curl-up, 20 curl-ups per minute). Stomach is kept firm to keep lower back on

ground.

New Crunch Curl

Subject curls the upper spine until the finger tips touch the second strip of tape and returns to the starting position.

The movement is slow and continuous. The individual performs as many curl-ups as

possible to the set cadence without pausing, up to a maximum of 60 secs (3 mins).

Check table for scores.

Press Up

The subject starts in the up position, arms straight, hands just outside shoulder width.

For push-ups, your body is supported by your hands and feet. For modified press-ups, your body is supported by your hands and the thighs just above the knee.

Your back should be straight and fingers pointed forward.

Your body should be linear from shoulders to end point of contact with ground.

Press Up The subject lowers his/her body until the

chest touches the tester’s fist, which is on the ground, and then raises back to the ‘up’ position.

The back must be kept straight. The abdominal muscles need to be contracted to stabilise the back.

The client should breathe out on the effort and in on the way down.

The score is the maximum number of correctly completed push-ups.

Refer to the scoring table.

Bench Press Subject should have technique practice on previous

days Subject should warm up Subject lies supine on a bench - knees bent, feet on

floor Subject grips the bar - hands wider than shoulder

width, wrists straight and directly overhead the elbows - in the down position.

Subject then extends the arms, pressing the barbell up, and repeats the movement to the rhythm of the metronome.

Bench Press

Subject should breathe regularly. Score the number of successful

repetitions. The test is finished when the subject is

unable to reach full extension or breaks the rhythm.

Refer to the scoring tables.

Muscular Strength

Strength is measured by means of 1RM Strength to BW ratio Estimated 1RM 10RM

1RM Strength to BW Ratio

Select muscle group Subject should be familiar with technique Establish wt. that can only be lifted once Allow rest between trials Record wt. lifted in lbs and divide by subjects

wt. in lbs. Refer to table for standards

Estimated 1 RM Familiarise subject with technique Record subjects’ BW in lbs. Start loads at .25% to .33% of BW for upper body

and .55% to .66% for lower body Perform the lift aiming to lift between 2 and 10 reps.If

more than 10 lifts then increase the weight. Calculate the 1RM by the following equation :

Weight Lifted 1.0278 - .0278(x) X = No. of Reps

10 RM

Familiarise subject with technique Find a weight subject can lift no more

than 10 times 10RM = 75% 1RMEG. Subject lifts 75KG 10 times.

1Rm = 100KGs

Measuring Body Composition

Hydrostatic weighing Bioelectrical impedance Body mass index Waist to hip ratio Skinfold callipers

Body Composition

Hydrostatic weighing: Archimedes principle: fat is less dense than water/muscle and bone is more dense, so a person with more bone and muscle mass and less fat will weigh more in water and have a greater density i.e. a lower % body fat and a greater % FFM.

Bioelectric Impedance

The resistance to an applied electric current is inversely related to the amount of the FFM. FFM has a greater water and electrolyte content and therefore greater conductivity than adipose tissue and bone. The greater the FFM, the greater the conductivity. % fat can be calculated by:

% fat = ((weight - FFM)/weight) .100

Body Mass Index

Measure body weight (kg)Measure body height (m), convert ins to cms by multiplying by 2.54. Divide by 100 to convert to metres.Square metres to convert to m2

Use formula kg/m2 and refer to tableDesirable range =20-25 kg/m2 Grade 1 Obesity =25-29.9 kg/m2

Grade 2 Obesity =30-40 kg/m2

Grade 3 Obesity=>40 kg/m2

Waist to Hip Ratio

Record measurements in cms or insWaist circ. (most narrow girth at umbilicus)Hip circ. (Largest girth of the buttocks)Waist circ./Hip circ.Standards: >.95(men) >.85(women) = increased risk of heart disease

Body Composition

Skinfold Measurement Procedures Take at right hand side of the body Grasp skinfold by the thumb and index finger Place calliper 1 cm below fingers Take two scores with a required accuracy of 1

mm; record average value Testers should have short nails Measure when skin is dry
