  UNIT -2 Sports and Nutritions

A diet which contains the proper amount of each nutrient, i.e. like carbohydrate, fat, protein etc is called Balanced Diet. A diet which consists of all the essential food constituents’ viz. protein, carbohydrates, fats, vitamins, minerals and water in correct proportion is called balanced diet. A balanced diet contains sufficient amounts of fiber and the various nutrients (carbohydrates, fats, proteins, vitamins, and minerals) to ensure good health. Food should also provide the appropriate amount of energy and adequate amounts of water.

Types of balanced diet

Balanced diet is divided into three parts-

A.Energy yielding food-it consists of carbohydrates and fats this food help to provide energy to individual for his workout or activities.

B.Bodybuilding Food-it consists of proteins it help in the growth and development of body.

C.Defensive food-it consists of vitamins minerals and water this food help in proper functioning and defence of various organs








(I) Fat soluble vitamin

Vit- A

Vit- D

Vit- E


(II)Water soluble Vitamins

Vit- B

Vit- C


(I)Major Minerals








(II) Trace Minerals








Nutritive Components of diet

CARBOHYDRATES- Carbohydrates are needed to provide energy during exercise. Carbohydrates are stored mostly in the muscles and liver. Complex carbohydrates are found in foods such as pasta, bagels, whole grain breads, and rice. They provide energy, fiber, vitamins, and minerals. These foods are low in fat. Simple sugars, such as soft drinks, jams and jellies, and candy provide a lot of calories, but they do not provide vitamins, minerals, and other nutrients.

PROTEIN-Protein is important for muscle growth and to repair body tissues. Protein can also be used by the body for energy, but only after carbohydrate stores have been used up. Only strength training and exercise will change muscle. Athletes, even body builders, need only a little bit of extra protein to support muscle growth. Athletes can easily meet this increased need by eating more total calories (eating more food).

Fat-It provides the highest concentration of energy of all the nutrients. One gram of fat equals nine calories. One pound of stored fat provides approximately 3,600 calories of energy. Saturated fats are found primarily in animal sources like meat, egg yolks, yogurt, cheese, butter, milk. This type of fat is often solid at room temperature. Unsaturated fats include monounsaturated and polyunsaturated fats, which are typically found in plant food sources and are usually liquid at room temperature.

Vitamin- A well-planned and nutritionally adequate diet should meet an athlete‘s vitamin and mineral needs. Supplements will only be of any benefit if your diet is inadequate or you have a diagnosed deficiency, such as an iron or calcium deficiency. Use of vitamin and mineral supplements is potentially dangerous and they should not be taken professional without the advice of a qualified health professional.

Minerals: – Mineral are very essential in our diet. Four percent of our body weight is made up minerals. These are required for healthy teeth, bones and muscles. It is also used by body for various activities such as transmission of nerve, impulses formation of hormones and maintenance of heart beat etc.

Macro Minerals: – a) Calcium: Calcium is among the top macro-minerals in terms of growth and development of our bones and teeth. It helps in blood clotting. Its deficiency may cause rickets. The sources are cheese, milk, orange, juice, eggs, green leafy vegetables and cereals.

b) Potassium: Potassium is one of the most required minerals in diet. It is helpful in keeping the nervous system and muscular system fir and active all the time. it helps in maintaining the amount of water in blood and tissues. Its main sources are banana, tomatoes, green leafy vegetables, beans etc.

c) Sodium: It helps in muscular activities. It also helps in transmission of nerve impulses. The sources are table salts, pickles and butter etc.

d) Magnesium: It repairs and maintains body cells. It is found in meat, brown rice, beans and whole grains etc.

Phosphorus: Phosphorus helps in the formation of bone and teeth. It keeps the muscles and nerve activities normal. The sources are egg, fish, liver, milk, and unpolished rice etc.

Micro Minerals:  a) Iodine: It produces the hormones for the thyroid gland. It is also significant for proper growth and development. Lack of iodine can cause goiter (swollen thyroid gland) and mental retardation. The sources are iodized salt, fish and sea food.

b) Iron: it is essential in the production of hemoglobin. Its deficiency causes anemia. The sources are meat, egg, dry fruits, spinach banana and greet leaf vegetables.

c) Chromium: it is essential in the production of hemoglobin. Its deficiency may cause diabetes. The sources are soya beans, black gram, carrot, tomato, groundnuts, bajra and barley.

Non-nutritive components of diet

a) Water

b) Roughage

c) Artificial sweeteners

d) Preservatives

e) Plant products

Fibre or roughage has no nutritive value. It is undigested part of the food or it can be said that it cannot be digested by human intestinal tract. It consists of water and improves intestinal function by adding bulk to the food. It helps the individual to satisfy the appetite. It prevents constipation.

Eating for weight control 

A healthy weight is considered to be one that is between 19-25 BMI. If the BMI is between 25-29 an adult is considered overweight and if it is above 30, the person is considered to be obese.

Since, 3500 calories equals both one equals about one pound of fat, if you cut 500 calories from your typical diet each day, you will lose one pound weight a week.

Here are some useful tips for weight control with proper eating:

a. Avoid common pitfalls: diet, especially fat diets or quick fix pills and plans, often set you up for failure. Prepare a plan that is more realistic.

b. Put a stop to emotional eating:  We don’t always eat simply to satisfy hunger. All too often, we turn to food for comfort and stress relief. When this happens, we frequently pack on pounds.

c. Tune in what you eat : Do not eat while at your desk or working, and in front of the TV screen. The result is that we consume much more than we need, often without realizing it. Counter this tendency by practicing “mindful” eating: pay attention to what you eat, savor each bite, and choose foods that are both nourishing and enjoyable

d. Fill up with fruit, veggies and fibre: to lose weight, you have to eat fewer calories. But that doesn’t necessarily mean you have to eat less food. You an fill up while on a diet, as long as you choose your foods wisely.

e. Indulge without overindulging: Do not avoid some type of food (ice cream or cookies or chips) completely. Instead of denying yourself the unhealthy foods you love, simply eat them less often.

f. Take charge of your food environment: Set yourself up for success by taking charge of your off environment: when you eat and what foods are available.

g. Make healthy lifestyle changes: You can support your dieting efforts by making healthy lifestyle choices .

Eating for weight control :- Factors to control body weight

Food  myths:

a. Eggs increases cholesterol level so avoid them: There is no doubt that eggs are good source of health. An egg provides you various nutrients. It is as per daily requirements of cholesterol by our bodies. So, if you take one egg daily there is no problem of cholesterol level.

b. Drinking while eating makes you fat: The actual fact behind this misconception is that enzymes and their digestive juices will be diluted by drinking water while eating which slows down your digestion which may lead to excess body fat.

(i) Myth: Low fat or No fat diet are good.

Fact: Body needs fats for energy, tissue repair and to transport vitamin A.D, E.K. Just cut down on salivated fat eating un saturated fats.

(ii) Myth Crash: Dieting or Fasting may loose weight.

Fact: It may be true in short term but ultimately it hinder weight loss. Loosing over the long term burns off fat whereas crash dieting or fasting not only removes fat but who leans muscles.

(iii) Myth: Food eaten late night is more fattening.

Fact: It doesn’t make much change.

(iv) Myth: Low fat milk has less calcium that full fat milk.

Fact:- Skimmed and semi skimmed actually have more calcium because it is in watery part and not in creamy part of milk.

(v) Myth: Vegetarian cannot build muscles.

Fact: Vegetarian can built muscles as meat eaters by getting their proteins from vegetables such as cheese nuts pulses. Etc.

(vi) Myth: Healthy food is expensive.

Fact: Tinned, stored, packed food is expensive. Whereas local & seasonal food is inexpensive.


An individual who is overweight wants to reduce weight they starve for reducing weight many times skip meals to lose weight, sometimes take slimming pills.

C. Food Intolerance

Food intolerance is that when a person has difficulty in digesting a particular food.

Symtoms : Nausea, Vomiting, Pain in joints, headache and rashes on skin, Diarrhoea, sweating, palpitations, burning sensations on the skin stomach.

Food Intolerance means the individual elements of certain foods that can not be    properly processed and absorbed by our digestive system. The main cause of food intolerance is the complete absence of enzymes responsible for breaking down or absorbing the food elements. Food intolerance can cause nausea, stomach pain, diarhhoea, vomiting, gas cramps,heartburn, headaches, irritability, etc.

Causes : Absence of activity of enzymes responsible for breaking down the food elements.

These are usually innate sometimes diet related or due to illness.

Management : Change in diet causing reaction some therapies like fructose intolerance therapy, lactose intolerance therapy, lislamine intolerance therapy can be applied.D. Food Myths/Dieting Myths

3.6 Sports Nutrition (Fluid & Meal in take, pre, during the post Competition)

Nutrition before competition: At least a week before the competition sportsperson       should take complex carbohydrate food which usually helps in increasing glycogen store. The fuel for the muscle is usually provided in meals 3-4 days prior to the competition. The diet should depend on the intensity of the activity. The diet should be rich carbohydrate, low in fat and protein. Two hours before the competition a high carbohydrate energy drink can be considered sufficient.

Nutrition during competition: It is important to stay hydrated and maintain sugar level so that sportsperson may not undergo fatigue. If the duration of the competition is more than 60 mins than ½ to 1 cup carbohydrate drink after 10-20 mins and if the duration is less than 60 mins than carbohydrate drink after every 20-30 mins.

Nutrition after competition: After competition it is important to recover properly , so the first preference should be given to replacement of fluid loss and this can be easily done by the intake of water or replacement drink. Meals after competition should be taken within 2 hours. For best glycogen restoration 100-200 grams of carbohydrate along with lean protein like meat or chicken should be taken. It will help in building, maintaining, and repairing of muscles. Atleat 20 gms of protein is required after completion for complete recovery.

Over the past several decades the participation of women in sports in sports field has increased tremendously. But really, it is a matter of regret for all of us to know that sports is such a field where gender inequality in strongly evident. The general social environment has not only inhibited women from participation in sports but has also criticise them when they participate. Many people comment for women “Why don’t they stay in the kitchen where they belong”?

But Now time has changed. Women are capable of changing society. Now the ideology suggests that women are participating in every sphere of life.

Unit-8 Biomechanics & Sports

Meaning of Biomechanics-

Biomechanics is the study of the structure and function of biological system by means of method of mechanics.


Biomechanics involve application of mechanical law to living structure.


Biomechanics is derived from Greek word' Bio and mechanics 'by humans living things and mechanics is a field of physics.

Importance of biomechanics-

  1. Understanding human movement

  2. Improved techniques

  3. Knowledge about forces acting on body

  4. Improve performance

  5. Efficient movement

  6. Correct movment

  7. Prevent injuries

  8. Knowledge about physics principles

  9. Guide safety principles

  10. Help in research work

  11. Improve the design of sports equipment

  12. Help in developing new tools

Types of Movement

Flexion-flexion is a bending movement that decrease the angle between a segment.

Example -

1.Bending the elbow 2.bending the leg at forward 3.bending of trunk

Extension-Extension is the opposite of flexion. it is a straightening moment that increase the angle between body parts.


1.Standing up from chair 2.Kicking the ball is stand

3 Extension of knee joint 4.lowering of dumbbell  

5.In extension of elbow etc.

Abduction-Application refer to a motion that pulls a structure or part away from the midline of the body.

Example -

1.Spreading of leg 

2.Splitting of legs 

3.Raising arm  to side word etc.

Adduction.Adduction refer to emotion that pulls a structure or path toward the midline of the body, Or towards the midline of a limb.


1. Bringing the legs close after splitting.

2. lowering the arms by side.etc.


A circular movement of a part.This is combination of Flexion,Extension , Abduction, Adduction and rotation.

Rotation-Movement of a bone around a longitudinal Axis .Medical rotation is movement in which the anterior aspect of limb turn towards the midline.

 Lateral rotation is movement in which the anterior aspect of  a limb turn away from the midline.

Elevation- elevation refer to moment in a superior direction. 


Shrugging is an example of elevation of the scapula.

Depression-Depression refers to movement in an inferior direction,the opposite of elevation.

Pronation-When in the anatomical position the fore arm is rotated so that the palm of the hand faces backward. if the elbow is flexed so that the forearm is horizontal and the palm of the hand is turned to face downwards.

Supination- The opposite of pronation. The palm of the hand is turned to face towards for upwards if the forearm is horizontal.


Plane-A plane is an imaginary surface through movement takes place. There are three planes of motion that pass through the human body.

1-Sagittal Plane- sagittal plane is an imaginary vertical surface which divides the body into right and left part or section.

2.Frontal plane-The frontal plane is also and imaginary vertical surface which divides the body into front (interior) and back (posterior) parts or section.

3.Transverse Plane-the transverse plane is an imaginary horizontal surface which divides the body into upper( superior) and lower (inferior) parts or section.

AXIS-An axis is an imaginary straight line around which an object/ part of human body rotates:

1- Saggital Axis-the sagittal axis also known as anteroposterior axis or dorsoventral axis.

2.Frontal Axis-It is also known as horizontal Axis or left right axis.

3.Vertical Axis- The Vertical axis is also known as longitudinal axis or craniocaudal axis.

Newton Law of motion and its application in sports

1.First law of Motion (Law of Inertia).this law states that an object at rest will remain at rest or in motion will remain in motion at a constant velocity unless acted upon by an external force.

Example-A football place at penalty point will remain at rest unless a player kick the ball to move the ball towards goal post. it will move in the direction where the player had exerted the force through kick.

2.Second Law of Motion-it is also named as law of momentum. according to this law of motion, the rate of change in velocity(acceleration)  of an object is directly proportional to the force applied and inversely proportional to the mass of body.

Force =Mass×acceleration

Example-  A volleyball player pushes the ball slowly for a drop whereas hits the ball hard for a smash.

3.Third law of Motion-(Law of action and reaction)

this Law of motion state that for every action there is equal and opposite reaction.

Example-an athlete push the starting block backward, in result athlete in pushed forward.
