2. What is physical fitness?
According to the Centers for Disease Control and Prevention
(CDC), physical fitness is defined as 'the ability to carry out
daily tasks with vigor and alertness, without undue fatigue,
and with ample energy to enjoy leisure-time pursuits and
respond to emergencies.'
4. COMPREHENSIVE HEALTH FITNESS EVALUATION
• Prescreening/risk classification.
• Resting HR, BP, height, weight, BMI, and ECG (if appropriate).
• Body composition.
• Waist circumference.
• Skinfold assessment.
• Cardiorespiratory fitness.
Submaximal or maximal test typically on a cycle ergometer or treadmill.
• Muscular strength.
1- to multiple-RM upper body (bench press) and lower body (leg press).
• Muscular endurance.
Ymca bench press,Curl-up test, Push-up test,isometric back strength,static squat
test.
• Flexibility.
Sit-and-reach test ,apleys back scratch test,trunk lift test.
5. I. BODY COMPOSITION
● Body composition is the proportion of fat and non-fat mass in your body.
● A healthy body composition is one that includes a lower percentage of body
fat and a higher percentage of non-fat mass, which includes muscle, bones,
and organs.
● Excess body fat, particularly when located centrally around the abdomen, is
associated with hypertension, metabolic syndrome,type 2 diabetes mellitus,
stroke, cardiovascular disease (CVD), and dyslipidemia.
Consists of :
1.Bioelectrical impedance analysis
2.Body mass index
3.Circumferences
4.Skin fold measurement
6. Bioelectrical impedance analysis
● Measures the impedance (Z) to the flow of a low-electrical current (800 μA), at a fixed
frequency (50 kHz).
● The principle of BIA is that Lean Tissue (LT), consisting of water and electrolytes, is a
good electrical conductor, while fat, which does not have water, is a poor conductor.
● Person stands on the machine ,electrodes are placed manually on wrist and ankle and
sends a small electrical current into a person and electrical signal
passes quickly through water that is present in hydrated muscle
tissue but meets resistance when it hits fat tissue.
● Once impedance is measured, body water and body fat percentage
is measured.
● People with an electronic medical implant, such as a pacemaker are
contraindicated as it interferes with its signaling.

7. BODY MASS INDEX:
● Body mass index (BMI) is a measure of body fat based on height and weight
that applies to adult men and women.
● The formula for BMI is
8. Circumferences
● Circumference (or girth) measurements may be used to provide a general
representation of body composition.
● The average of the two measures is used provided they do not differ by
more than 5 mm by tape measurement.
● SITES:

10. Skinfold measurements:
● Principle-It measures the subcutaneous fat folds at specific sites of body.
● Skinfold measurements is done by skinfold calliper(Harpenden).
● The tester pinches the skin at the appropriate site to raise a double layer of
skin and the underlying adipose tissue, but not the muscle. The calipers are
then applied 1 cm below and at right angles to the pinch, and a reading in
millimeters (mm) taken two seconds later.
● 7 COMMON SITES-
● Triceps,chest,midaxillary,subscapular,
suprailiac,abdominal,thigh.

12. II.MUSCLE STRENGTH
● Muscular strength refers to the muscle’s ability to exert force per unit of time.
● Strength can be assessed either statically (i.e., no overt muscular movement
at a given joint or group of joints) or dynamically (i.e., movement of an
external load or body part in which the muscle changes length).
Assessment methods:
● 1 RM tests ( 1 RM bench press for upper and leg press for lower extremity)
● Isokinetic strength test
● Handgrip strength test
● Pinch strength
● Straight leg abs strength test
13. 1-RM Tests (Repetition maximum tests)
Procedure: One repetition maximum tests (1-RM) is a popular method of
measuring isotonic muscle strength. It is a measure of the maximal weight a
subject can lift with one repetition. It is important to reach the maximum weight
without prior fatiguing the muscles. After a warm up, choose a weight that is
achievable. Then after a rest of 3-5 minutes, increase the weight and try again.
The person chooses subsequent weights until they can only repeat one full and
correct lift of that weight.

17. Straight leg lift abs strength-
● Purpose: Estimate the degree of abs strength.
● Supine with arms across the chest,head rested on floor.Both legs are raised
to a 90-degree angle (vertically) while keeping the upper body flat on the
floor.The subject aims to sustain the pressure on the tester's fingers under the
lower back by contracting the abdominals as the legs are lowered.
● The subject slowly lowers both legs until the pressure on the hand behind the
back disappears and lowest angle is measured with goniometer or protractor.
18. III.ENDURANCE TEST
● Muscular endurance is the ability of a muscle group to execute repeated
muscle actions over a period of time sufficient to cause muscular fatigue or to
maintain a specific percentage of the 1-RM for a prolonged period of time.
● Simple field tests- Curl-up (crunch) test , push-ups that can be performed
without rest used to evaluate the endurance of the abdominal muscle groups
and upper body muscles, respectively.
● Other test used are Isometric back strength test,static squat test.
YMCA bench press
● Measures endurance of upper extremity and shoulder girdle.
● Performs standardized 30 reps /min. Men are tested using a 36.3-kg (80 lb)
barbell and women using a 15.9-kg (35 lb) barbell. Subjects are scored by the
number of successful repetitions completed.
20. Push up test
● Assess the endurance of (anterior deltoid, pectoralis major, triceps,abdominals)
● The push-up test is administered with men starting in the standard “down”
position and women in the modified “knee push-up” position (legs together, lower
leg in contact with mat with ankles plantar-flexed, back straight, hands shoulder
width apart, head up,using the knees as the pivotal point).
● The subject must raise the body by straightening the elbows and return to the
“down” position, until the chin touches the mat. The stomach should not touch the
mat.No of pushups without rest is counted.
Partial curl up
● In supine across the tape,knees bent to 90,with feet on the floor and arms
extended to their sides,subjects are to flex their spines to 30°until their fingers
touch the second strip of tape.
● A metronome is to be set at 40 beats/ min .At the first beep, the subject
begins the curl-up, reaching the top position at the second beep
21.
22. Isometric Back Strength Test
● Assess the erector spinae and multifidus.
● Subjects must lie face down on a bench, with their upper body from the waist
hanging over the end of the bench. The subject's feet must be held or
strapped down, and the arms by their side or clasped behind the back. When
ready, they must bring their body up to the horizontal position, and hold this
for a set period (e.g. 45 seconds).
Static squat test
● Subject stands on both feet with the back to a wall, hips and knees flexed to a
90° angle. Instruct to hold this position as long as possible and record the
time in sec.
24. IV.Flexibillity test
● Flexibility has been defined as the range of motion of muscle and connective
tissues at a joint or group of joints.
● It improves mobility, posture, reduces the risk of injuries
and muscle soreness.
25. SIT AND REACH TEST
● Assess low back and hamstring flexibility.
● Sit straight with leg straight,shoes removed,soles flat against the box,both
palms facing downwards hands top on each other,subject reaches forward
along the measuring line as far as possible without bending the knee.
● The subject reaches out and holds that position for at one-two seconds while
the distance is recorded in cms.26cm ruler is used with ht of box 30cm.
26. APLEY’S BACK SCRATCH TEST
● Assess shoulder arm and upper girdle flexibility.
● Test 1-Reach behind head and touch sup medial
angle of scapula.
● Test 2-Behind the back and touch inf angle of
scapula.
UPPER TRUNK FLEXIBILITY TEST
● Assess trunk extensor flexibility.
● In prone,hands placed under the thighs,place
coin at eye level maintain focus on throughout
the movement on coin,when ready, the upper
body is lifted off the floor, in a very slow and
controlled manner, to a maximum height of
12 inches, hold for 3 sec andmeasure with
scale at chin level.

49. Agility
Illinois Agility Test(Getchell, 1979)
• Setup
⮚ The cones should be set up using the measurements provided.
⮚ Four cones are placed on the corners of a 5- x 10-meter rectangle.
⮚ Four additional cones are placed in a straight line that runs through
the center of the rectangle.
⮚ Starting from the bottom/center, the four cones are placed 3.3
meters apart with one cone on the top line and another on the
bottom line of the rectangle.
⮚ The runner begins in a stationary position behind the starting mark
and holds the position for one second.
50. • Procedure
⮚ On command, the runner takes off into a sprint and the timer
starts the stopwatch.
⮚ The runner sprints 10 meters, touches the line at the first cone
with the left foot, sprints to the first of the middle four cones, and
zigzags between them.
⮚ Once the last cone has been circled, the runner runs to the top
right corner of the box, touches the line at the first cone with the
right foot, and sprints through the finish line.
⮚ The timer stops the stopwatch when the runner's hips cross the
finish line.
52. Agility T-Test
⮚ The T-Test is a simple running test of agility, involving forward,
lateral, and backward movements, appropriate to a wide range of
sports.
• procedure
⮚ The subject starts at cone A. On the command of the timer, the
subject sprints to cone B and touches the base of the cone with
their right hand.
⮚ They then turn left and shuffle sideways to cone C, and also
touches its base, this time with their left hand.
⮚ Then shuffling sideways to the right to cone D and touching the
base with the right hand.
⮚ They then shuffle back to cone B touching with the left hand, and
run backwards to cone A.
⮚ The stopwatch is stopped as they pass cone A.

Power is the product of strength and speed. When we perform a task as quickly
and as forcefully as we can, the result is powerful. For example, a sprint start, a
shot-put or javelin throw or long-jump.
55. Power
Margaria Kalamen Power Test
⮚ The Margaria Kalamen Power Test is a simple test of power of the
lower extremities, involving running up a flight of stairs.
⮚ The test described here was introduced by Kalamen (1968), and is
a variation of the original Margaria Step Test developed by
Margaria et al. (1966)
56. • Procedure
⮚ A starting line 6 metres in front of the first step; the 3rd, 6th and
9th step clearly marked with tape or chalk.
⮚ Measure and record the athletes weight.
⮚ Measure and record the vertical distance between the 3rd and 9th
steps.
⮚ The athlete takes 2 or 3 practice runs up the steps to warm up.
⮚ On the command "Go", sprint from the start line to the stairs, then
spring up three steps at a time (i.e. landing on the 3rd, 6th and 9th
stairs).
⮚ The assistant records the time from the 3rd step to the 9th step.
⮚ Repeat twice more, with a 2-3 minute recovery between each test.

58. Vertical Jump Test (Sargent Jump, Vertical Leap)
⮚ The vertical jump test is a test of lower body power. The test was
first described nearly 100 years ago (Sargent, 1921).
• Procedure
⮚ The athlete stands side on to a wall and reaches up with the hand
closest to the wall.
⮚ Keeping the feet flat on the ground, the point of the fingertips is
marked or recorded. This is called the standing reach height.
⮚ The athlete then stands away from the wall, and leaps vertically as
high as possible using both arms and legs to assist in projecting
the body upwards. The jumping technique can or cannot use a
counter movement.
⮚ Attempt to touch the wall at the highest point of the jump. The
difference in distance between the standing reach height and the
jump height is the score. The best of three attempts is recorded.

60. Seated Medicine Ball Throw
⮚ This test is also called the medicine ball chest pass.
⮚ The "Seated Power Throw" test, part of the US Army
Occupational Physical Assessment Test, is very similar that
described below, though using a 4.4 pound (2 kg) medicine ball.
⮚ This test measures upper body (arm) strength and power, by
keeping the back in contact with the wall the strength of the arms
only are tested.
61. • Procedure
⮚ The athlete sits on the floor with his legs fully extended, feet 24
inches (~60 cm) apart and with the back against a wall.
⮚ The ball is held with the hands on the side and slightly behind the
center and back against the center of the chest.
⮚ The forearms are positioned parallel to the ground.
⮚ The athlete throws the medicine ball vigorously as far straight
forward as he can while maintaining the back against the wall.
⮚ The distance thrown is recorded.
• Scoring
⮚ The distance from the wall to where the ball lands is recorded.
⮚ The measurement is recorded to the nearest centimeter (other
protocols have used the nearest 0.5 foot or 10 cm).
⮚ The best result of three throws is used.

64. Reaction Time
Reaction Time Ruler Test
⮚ This test uses the known properties of gravity to determine how
long it takes a person to respond to the dropping of an object by
measuring how far the object can falls before being caught.
⮚ Aim is to measure reaction time, hand-eye quickness and
attentiveness.
⮚ equipment required: 1 meter long ruler or Yardstick, calculator.
65. • Procedure
⮚ The person to be tested stands or sits near the edge of a table,
resting their elbow on the table so that their wrist extends over the
side.
⮚ The assessor holds the ruler vertically in the air between the
subject's thumb and index finger, but not touching. Align the zero
mark with the subjects fingers.
⮚ The subject should indicate when they are ready.
⮚ Without warning, release the ruler and let it drop - the subject
must catch it as quickly as possible as soon as they see it fall.
⮚ Record in meters the distance the ruler fell. Repeat several times
(e.g. 10 times) and take the average score.
66. • Calculation
⮚ Calculate the average distance the meterstick fell.
⮚ Use the table below to determine how long it took the ruler to fall
the measured distance (distance in cm, time in seconds).
⮚ The table is based on the following formula,
⮚ t = sqrt ( 2d / g )
where d = the distance the ruler fell in meters
g = the acceleration of gravity (9.8 m/s^2)
t = the time the ruler was falling (seconds)
