Measurement and EvaluationClass 11 Health And Physical Education Notes

What are Test, Measurement and Evaluation?

In our daily lives, we are always curious about how things work and why they happen. To understand our own abilities, skills, or the results of our efforts, we rely on a process involving test, measurement, and evaluation. These three concepts are closely linked and work together in a continuous cycle. An idea can't be properly developed without evaluation, which relies on measurement, and measurement can't happen without a suitable test.

Test

A Test is a tool used to gather information about an individual. It helps determine specific qualities or characteristics related to their knowledge, physical fitness, or skills.

Measurement

Measurement is the result or data you get from a test. It's often a score, a numerical value, or a grade that shows an individual's capacity or ability. Measurement can be quantitative (a number) or qualitative (a description).

Evaluation

Evaluation is the process of making sense of the data collected through measurement. It involves interpreting the scores to make a professional judgment about their value or worth. After taking a test, evaluation provides feedback and shows the effectiveness of the process.

The evaluation process involves three sequential steps:

1. Process education
2. Objectives
3. Learning experiences and change of behavior

Measurement and Evaluation of Selected Physical Fitness Components

Here we will explore how to measure and evaluate some of the major components of physical fitness.

Muscular Strength

Muscular strength is the ability of a muscle or a group of muscles to exert force against resistance. Several factors influence muscular strength, including:

• Physiological factors: The size of the muscle, the ratio of slow and fast-twitch muscle fibers, and coordination between muscles.
• Psychic factors: Your state of mind, such as anger, motivation, or aggression, can positively or negatively affect your strength.

To measure strength accurately, one must know which exercises target specific muscles. Muscular strength can be measured using your own body weight or with equipment like a dynamometer or barbells.

Tests related to Muscular Strength

Push-up

The push-up test measures the muscular strength and endurance of the upper body.

• Equipment: You may need a floor mat and a stopwatch.
• Procedure:
  1. Start in a plank position with your hands and toes on the floor. Your hands should be shoulder-width apart, and your body should form a straight line from your head to your ankles.
  2. Keeping your back and knees straight, lower your body until your elbows are at a 90-degree angle.
  3. Push back up to the starting position with your arms fully extended.
  4. Repeat this action until you are exhausted or can no longer maintain the correct form and rhythm.
• Scoring: The score is the maximum number of correct push-ups completed within a specific time or at a set rate.

Abdominal Curl

This test assesses the muscular strength and endurance of the abdominal muscles.

• Equipment: A floor mat and a stopwatch are required.
• Procedure:
  1. Lie on your back (supine position) with your knees and elbows bent (flexed).
  2. Clasp your fingers together behind your head.
  3. Raise your upper body and then return to the starting position.
  4. Repeat this movement for a set amount of time.
• Scoring: The score is the total number of curl-ups completed in the specified time.

Squat thrust

This test is used to assess the muscular strength and endurance of the lower body.

• Procedure:
  1. Begin in a standing position.
  2. Drop into a low squat and place both palms on the floor.
  3. Quickly kick both legs back into a plank position.
  4. Quickly return to the standing position.
• Scoring: The score is the maximum number of squat thrusts performed in one minute.

Muscular Endurance

Muscular endurance is the ability of your muscles to perform an activity for an extended period. It is related to the duration of an activity and is sometimes called stamina. Slow-twitch muscle fibers are primarily responsible for endurance activities.

Tests related to Muscular Endurance

1000 Metre Run or Walk Test

This test is a common way to assess cardiovascular endurance.

• Equipment: A running track and a stopwatch.
• Procedure: Participants start at the starting line and must cover a distance of 1000 meters in the shortest time possible. Walking is permitted.
• Scoring: The score is the time taken to complete the 1000 meters, recorded in minutes and seconds.

Flexibility

Flexibility refers to the range of motion around your joints. It is the ability of joints and muscles to move with a greater range, which helps in performing movements with less muscle tension.

Test related to flexibility

Sit and Reach Test

This test measures the flexibility of the lower back and hamstring muscles.

• Equipment: A sit-and-reach box and a mat.
• Procedure:
  1. Sit on the floor with your legs extended straight out in front of you (long sitting position).
  2. Place the soles of your feet flat against the sit-and-reach box. Your knees must remain straight and on the ground.
  3. Place one hand on top of the other with palms facing down.
  4. Lean forward smoothly, sliding your hands along the measuring scale on the box as far as possible without any jerky movements.
• Scoring: The score is the distance you reached, recorded in centimeters.

Body Mass Index (BMI)

Body Mass Index (BMI) is a calculation that helps determine an individual's level of obesity. It is calculated by dividing a person's weight by the square of their height.

Measurement of Body Weight

• Equipment: A weighing machine.
• Procedure: Stand on the weighing machine wearing minimal clothing. The reading should be recorded in kilograms.

Measurement of Height

• Equipment: An Anthropometer or Stadiometer.
• Procedure: Stand straight against a wall with your back and head touching it, looking forward. The measuring bar should touch the highest point of your head. The reading is noted in centimeters.

BMI Calculation

The formula for BMI is: BMI = Weight in Kg / (Height in meters)²

The World Health Organization (WHO) provides norms to categorize BMI scores for adults:

• Underweight: Below 18.5
• Normal (healthy weight): 18.5 to 24
• Overweight: 25.0 to 29.9
• Obesity: 30 and above

Waist-to-hip ratio (WHR)

The Waist-to-hip ratio (WHR) helps determine fat distribution in the body and evaluate overall health. Carrying more weight around your middle (waist) compared to your hips can indicate a higher risk for certain health issues.

The ratio is calculated by dividing the waist measurement by the hip measurement: WHR = Waist Measurement / Hip Measurement.

The World Health Organization (WHO) provides the following risk levels based on WHR:

• Men:
  • Low risk: .95 or less
  • Moderate risk: .96 to 1.0
  • High risk: 1.0 or higher
• Women:
  • Low risk: .80 or less
  • Moderate risk: .81 to .85
  • High risk: .85 or higher

Measurement procedure

1. Waist: Stand straight and breathe out. Place a measuring tape around your waist, just above your belly button, and record the measurement in centimeters.
2. Hip: Place the tape around the widest part of your hips and take the measurement.

Somato Types (Endomorphy, Mesomorphy and Ectomorphy)

In the 1940s, American Psychologist William Herbert Sheldon proposed a theory of three basic body types, or somato types. These physical characteristics are still used today when designing workout routines.

Endomorph

An endomorphic individual typically has a larger frame with shorter arms and legs. Their body mass can make it difficult to compete in sports that require speed or agility.

• Characteristics:
  • Pear-shaped body with a rounded head
  • Wide hips and shoulders
  • Tends to carry a lot of fat on the body, especially upper arms and thighs
  • Gains weight easily and can lose fitness quickly if training stops
• Sports Suitability: They are well-suited for sports requiring pure strength, like powerlifting. Their bulk can be an advantage in sports like rugby, and their large lung capacity can be beneficial for rowing.

Mesomorph

A mesomorphic individual naturally excels in activities requiring strength, agility, and speed. They have a medium build and can gain muscle easily.

• Characteristics:
  • Wedge-shaped body with a cubical head
  • Wide, broad shoulders and narrow hips
  • Muscled arms and legs with minimal body fat
  • Can gain or lose weight easily
• Sports Suitability: Their build makes them strong candidates for being top athletes in almost any sport. They respond well to both cardiovascular and resistance training.

Ectomorph

An ectomorphic individual is typically long, slender, and thin. Their lack of natural muscle mass makes them less suited for power and strength sports.

• Characteristics:
  • High forehead and receding chin
  • Narrow shoulders, hips, chest, and abdomen
  • Thin arms and legs with little muscle and fat
• Sports Suitability: Ectomorphs often dominate endurance sports and gymnastics. While they can get lean easily, their lack of muscle limits their ability in sports that require mass. They are also more susceptible to injuries.
