Children and Sports

Sport and physical education are fundamental to the early development of children and youth and the skills learned during play, physical education and sport contribute to the holistic development of young people. This post provides information about changes in the body of children due to sports.

Motor Development in Children

Motor development refers to the development of a child’s bones, muscles and ability to move around and manipulate his or her environment. 
Motor development can be divided into two sections: Gross Motor Development and Fine Motor Development:

  1. Gross Motor Development involves the development of the large muscles in the child’s body. These muscles allow us to sit, stand, walk and run, among other activities. Games involving gross motor skills are dodge ball, climbing over, play gym equipment, hopscotch, kick to kick, indoor hockey with rolled newspaper and stocks. eg.: running, jumping, hopping, skipping, ball games, and climbing.
  2. Fine Motor Development involves the small muscles of the body, especially in the hand. needs developed control of muscles to allow for more complicated or complex movements. eg.:handwriting, painting, cutting out images etc.

Factors Affecting Motor Development in Children

Motor Development in children depends on and is affected by the following factors:
  1. Age or Maturity: Motor Development does not take place overnight. It takes place gradually in a phased manner as the age advances. Infancy and preschool years are a period of rapid motor development. It slows down in later years. Later childhood and late adolescence are the periods of consolidation and therefore growth and motor development slow down.
  2. Genetic Influence: Genes or Heredity are the qualities that affect the motor development of an individual. They set limits for the development of motor abilities in future even if environmental factors such as diet, air and exercise etc. are available adequately.
  3. Nutrition:  Nutritious foods help in promoting motor development. Energy from foods is the essential requirement for muscular activity. This nutritious food, not only helps in performing the muscular activity, but also promotes the growth of muscles and development of motor ability.
  4. Environment: Encouragement, love and security of children, help them to take risks to know more about the environment. This effort leads to the better sensory development of children which is the prerequisite of motor development. 
  5. Practice: Practice of activities helps in developing skilled voluntary movements. Children are practising to see what they can do. They have no targets to achieve but are curious. For this reason, they seem to love practice This leads to motor development.
  6. Opportunities: Motor development of children is affected greatly by the opportunities and facilities available to them for play activities in schools, homes and neighbourhood. Play and play related activities are the most important factor that affects motor development in children.
Actually, childhood is the "play age" that lays the foundation for health, fitness and skilful motor development.

Physical and Physiological Advantages of exercise for children

The benefits of regular exercise on children can be listed under 2 heads i.e. Physical and physiological (You can see the difference between physical and physiological here) as given below:

Physical Benefits

  1. The muscles of children increase in size as a result of higher exercise which is reflected in their muscular appearance.
  2. They gain in height due to increase in the length and structure of bones.
  3. Their body weight increases.
  4. The body assumes correct, erect posture.
  5. The texture(appearance) of their skin improves.
  6. Their movements become well-coordinated and skilful.
Physiological Benefits

  1. Muscles of the body and various organs become strong
  2. The storage of nutrients (glycogen) muscles, increases which can be utilised when required.
  3. Body weight increases. 
  4. Bones become well-calcified. 
  5. The stroke volume of the heart increases. 
  6. The capacity to do a physical activity for a longer period before exhaustion increases gradually. 
  7. The capability of utilising oxygen during exhausting exercise increases.
  8. The return of heart rate and blood pressure to normal levels after an activity becomes quick. 
  9. Neuromuscular coordination increases.

Weight Training

Weight training is a superb method to shape the whole body. However, this training method requires the judicious utilisation of weights and carefully selecting weight exercises. In weight training, we use light and medium weights in weight training exercises for the development of strength, agility, flexibility and endurance.

Advantages of weight training

  1. Weight training improves muscular strength. 
  2. It increases muscular tone.
  3. It improves muscular endurance.
  4. Weight training strengthens bones. 
  5. It makes children less prone to injuries. 
  6. It increases the self-confidence of children.
  7. It decreases resting blood pressure.
  8. It increases the level of HDL(high-density lipoprotein) in blood.
  9. It decreases the time of retention of food in intestines, thus reducing the risks of intestinal disease.
  10. The resting heart rate is lowered. 
  11. Improves balance and coordination. 
  12. It improves posture. 
Disadvantages of Weight Training 
  1.  Weight training exercise can lead to injuries of muscles or joints if the exercises are not done properly. 
  2. It can decrease flexibility if flexibility exercises are not done along with such training .
  3. Over a length of time, it may have a bad effect on joints .
  4. Very often there is a need of a partner while doing exercises.

Food Supplements

Children's diet needs special attention as that is the time when the foundation of their future health is laid. As a matter of fact, there should be no need for food supplements for children if their diet is well balanced and sufficient to meet their body needs. But in many cases, the diet the which take may be lacking in their body account of the and type of foodstuffs eaten. Very often the foodstuff eaten are deficient in the required food value.
This may be due to the following reason 
  1.  The vegetables and fruits we eat are transported over long distances and in many cases are kept in cold storages for long and their nutrients.
  2. Our crops, vegetables and fruit plants are sprayed with pesticides and injected with other chemicals for better output. Thus such foodstuff may do more harm than good. 
  3. The preservatives added to some of the sauces, tinned fruit& vegetables and other preserved eatables result in the loss of their nutrients.
  4. Our cooking practices result in the loss of vitamins and nutrients from our foods. 
  5. Eating junk food gives children little or no nutrients.
 Although vitamins, minerals and other food supplements are not a substitute for a healthy, balanced diet but they become a necessity in many cases. 
Food supplements for children can be of advantage or disadvantage depending upon their requirements. Therefore food supplements should not be taken unless prescribed by a doctor because taking food supplements without need may do more harm than good.

CBSE class 10 board to come back from 2017-18

23:45:00 Posted by Saurabh Sahni
CBSE is likely to reintroduce board exam in class 10 from session 2017-18. It means those who are studying in class 9 this year, will have to sit in board examination next year. The comeback of board exam was being expected from the very first day when Mr Prakash Javadekar took charge as HRD minister. A few weeks back, CABE (Central Advisory Board on Education) meeting was held and most of the stakeholders supported the move. However, it was not in agenda of CABE meeting but a general consensus was built around it.
Mr Javadekar has confirmed the comeback of board examination today in an informal conversation with reporters after a meeting with the Rajasthan Education Minister. “We will implement it from the 2017-2018 session. Not this year or in the next two months. The final decisions will be announced soon, it is under final consideration,” Mr Javadekar said.
CBSE made the board examination optional in the year 2010 and it was made almost mandatory to sit in the school-based home examination in KVs and govt. schools. Board exam was being conducted only for those who were willing to go out of CBSE system. However, in both of the cases, CBSE was awarding the same certification to the board and home exams.
The worst part of this system is that CBSE was conducting board exam for 30 marks only and rest of the 70 marks were being awarded by schools. Many state boards were not ready to accept marks awarded by schools while taking admission in class 11. Thus the whole process was too much confusing and was inviting interrogative remarks.

Sports and Nutrition

For most basic level, nourishment is very important to athletes because it provides a source of power required to perform the activity. The foodstuff we eat impacts on our strength, training, performance and recovery. Not only is the sort of food important for sports nutrition, but the times we eat during the day also has an impact on our performance levels and the body capability to recover after training.

Meals eaten before and after exercise are the main in sports nutrition, but you should really be cautious with everything that you put in your body. Since a general rule of thumb, athletes should eat about two hours before exercising and this meal should be high in carbohydrates, low in extra fat and low to modest in protein. Carbohydrates are the key source of energy that powers your exercise regime and protein are required to aid muscle growth and repair. Following exercising, you need to replace the carbohydrates you have lost and you must ensure proper muscle restoration by including protein in your post-training meals.

This topic is divided into further 5 types: Balanced diet, components of the diet, eating disorder, controlling weight, effects of diet on performance.

Balanced Diet

Meaning of Balanced diet
A diet which is composed of all essential constituents necessary for the growth and maintenance of the body is known as the balanced diet. Necessary constituents of a balanced diet are carbohydrates,proteins,fats,vitamins,minerals,roughage and water. 

Advantages of balanced diet
  1. Ensures a supply of nutrients in the body.
  2. Essential for optimal growth and development of the body.
  3. Prevent deficiency diseases.
  4. Prevent obesity.


Nutrients are those components of diets which are used as a raw material to give more output in the form of activity.The process of taking in nutrients in, digesting ,absorbing and distributing it to tissues for utilisation.

Types of Nutrients

Macro-Nutrients- Nutrients which are required by the human body in larger quantities are known as macro-nutrients. Also due to their importance, they are required in more quantities. Macro-nutrients serve as the raw material for growth and maintenance. Macro-nutrients consist of Fat,Proteins, and Carbohydrates.
  1. Fat- Fat is one of an essential part of our diets. Fat is helpful in absorbing fat-soluble vitamins such as Vitamin-K,Vitamin-A,Vitamin-D,Vitamin-E. Such fat-soluble vitamins cannot be absorbed without some fat in the diet. Fat also supplies the body with energy. It contains more energy than any other source of  energy ( 9 calories per gram ). There are two types of fats: Saturated fats and Unsaturated fats. Saturated fats ( trans fats) are related to negative health effects including heart diseases. on the other hand, Unsaturated fats are known to lower the risks of some diseases ( including some cancer and heart diseases ). Additionally,Unsaturated fats lower down bad cholesterol and raise levels of good cholesterol.
  2. Proteins- Protein is a nutrient required by our body for growth.Every cell in the human body contains protein. The basic structure of the protein is a chain of amino acids.Proteins are helpful in repairing damaged tissues, the growth of nails, hair etc.\
  3. Carbohydrates- Carbohydrates are one of the essential components of our diet. They contain elements of carbon,oxygen, and hydrogen. They are in the form of sugar particles and are broken down into glucose to be digested by our body. Glucose is the most preferred source of energy for the brain, heart and central nervous system. Carbohydrates should be available in our diet up to 65% so that heart,brain and CNS get proper supply of fuel.
Carbohydrates are found in sweet products such as sweets , fruits, vegetable etc. Individual should rely on natural sources of carbohydrates which also provide fibres and are available in such quantities that do not affect our regular body functions.
Micro Nutrients

Nutrients which are required in less quantity by our body are known as micronutrients. micronutrients are classified into Vitamins and Minerals. They are required in minute quantity to enable various chemical reactions in our body. Description of vitamins and minerals is given below:

  1. Minerals- Minerals are an important constituent of our diet. Would you ever notice how TV commercials for lunch break cereal always mention nutritional vitamins and minerals? However, when you think of vitamins, food isn't the initial thing that occurs to you. Usually are minerals something you will find in the soil, like iron and quartz.Well, yes, but small amounts of some mineral deposits are also in foods - for instance, red meat, such as ground beef, is a good source of iron.Much like nutritional vitamins, minerals help your system expand, develop, and stay fit.The body uses nutrients to execute many different functions - from building strong bones to transmitting nerve system impulses. Some minerals are even used to make hormones or maintain a normal heartbeat. Some examples of minerals are calcium, phosphorus, sodium, chlorine, magnesium, potassium, and sulphur. 
  2. Vitamins-  Vitamins are chemicals which are required in our body in small quantities. If             vitamins are not take in proper quantities, it may cause a deficiency disease. For example.         deficiency of  vitamin c causes scurvy. Vitamins are categorised into following two types:
Fat Soluble Vitamins

Fat soluble vitamins are those vitamins which require some fat to perform their functions. These vitamins are Vitamin K,Vitamin A,Vitamin D,Vitamin E. 
  • Vitamin K- The main function of vitamin K is to clot the blood.This vitamin is used by the body to prevent excess loss of blood by any means such as haemorrhage or wound. Its main sources are all the leafy vegetables (kale,spinach,broccoli,cabbage,turnip leaves,mustard leaves etc. ),egg,meat,wheat,cereals etc. 
  • Vitamin A- Vitamin A has multiple featuresit is essential for growth and improvement, of the immune system and vision.It is also helpful in formation of bones and teeth. Deficiency of Vitamin A can lead to lots of deficiency diseases but in all of them, night blindness is most common. Sources of Vitamin A are cod liver oil, liver, capsicum, red ,sweet potato,carrot ,broccoli leaf, butter,kale ,spinach ,egg .apricot .papaya ,tomatoes.mango,pea,milk etc.
  • Vitamin D- Vitamin D is required by our body to help in absorption of Vitamin c and potassium. Vitamin D is found in Fatty fish, like tuna, mackerel, and salmon;Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals,Beef liver,Cheese,Egg yolks etc.If our body fails to get adequate Vitamin D then it results in deficiency diseases like rickets, osteomalacia,dental cavities, and osteoporosis.
  • Vitamin E- Similar to Vitamin K , Vitamin E also helps to clot the blood. Functions of Vitamin E are It helps to balance cholesterol, prevent disease development,repairs damaged skin, thickens hairs, balances hormones,improves vision, improve endurance and muscle strength. It is found in sunflower seeds,almonds,hazelnuts,mango,avocado, broccoli, spinach,kiwi, tomato, etc.
Water Soluble Vitamins

Water soluble vitamins are those vitamins which require water to perform their functions. Water soluble vitamins are Vitamin - B and Vitamin - C.

  • Vitamin-B- Vitamin B consist of eight soluble vitamins that play important roles in cell metabolism. Earlier they were thought to be a single vitamin but later on research showed that they were chemically distinct vitamins. Now they are referred to as vitamin "B" complex. Sources of vitamin B are Liver (Beef), Mackerel, Sardine, Fortified Cereals,Red Meat,Salmon,Fortified Soy,Milk,Swiss Cheese,Yogurt etc. Deficiency diseases are Beri- Beri,grey hair,unhealthy skin, anaemia, impaired growth, depression etc.
  • Vitamin C- Vitamin C is a white crystalline substance. Vitamin C helps in healing the wound. It increases the metabolic rate and helps in absorbing calcium. It also works as the antioxidant. It is essential for the formation, growth, and repair of bones, skin and connecting tissues.It  also  maintains healthy  teeth and gums. The deficiency of Vitamin C causes scurvy. Deficiency also makes adults feel tired, weak and irritable. Vitamin C is found in fruits and vegetable with citric acid and the ascorbic acid such as lemons, oranges, pineapples,guava,amlaber,tomato,green chillies and apples etc. 

Components of Diet 

Components of Diet are classified into :

A. Nutritive Components of Diet

B. Non-Nutritive Components of Diet 

A. Nutritive Components of dietNutritive Components of diet are those components which contribute or provide energy or calories. There are various nutritive components of diet which are described below:

  • Proteins- The maximum amount of protein remains in the tissues of our body . Besides this , protein is also found in blood. Secretion of endocrine glands, bones, teeth and in delicate tissues. Our physical growth will be retarded if we take less amount of protein in our food. Along with this, protein also plays an important role in the mental development of an individual. . Besides this , protein is also found in blood. Secretion of endocrine glands, bones, teeth and in delicate tissues. Our physical growth will be retarded if we take less amount of protein in our food. Along with this, protein also plays an important role in the mental development of an individual. Sources of protein are eggs, milk, milk products, meat, fish, pulses, soybean, mustard, groundnuts, dry fruits etc.
  • Carbohydrates- Carbohydrates are like fuel in our body. Carbohydrates provide us energy. We also require carbohydrates  for the formation of fats. The quantity of carbohydrates intake depends on upon the daily routine of the person. Sources of carbohydrates are rice, maize, jawar, bajra, pulses, gram, dry pea, date, grapes, potato, banana, jaggery and sugar.
  • Fat- Fat is also an essential nutritive component of food. fat provides heat and energy to the body. It helps in regulation of body temperature and protects us from external effects of hot and cold temperature. Its accurate quantity makes body beautiful. Excess of fat results in deposition of fat in body and reduction in efficiency of body organs.Sources of fats include ghee, butter, curd, fish oil,milk, meat, egg, dry fruits, coconut, soybean, foodgrains, mustard oil and cottonseed, etc.
  • Vitamins- Vitamin is also an essential nutritive component of food. Vitamins are very important for a healthy life. Vitamins protect us from various types of diseases and also contribute to the growth of our body. There are 2 types of vitamins: Water soluble vitamins and Fats soluble vitamins. Vitamins which make a solution with fats to perform their functions are called fat soluble vitamins and Vitamins which make a solution with water to perform their functions are called water soluble vitamins. Fat soluble vitamins include Vitamin K, Vitamin A, Vitamin D, Vitamin E. Water soluble vitamins include Vitamin B and Vitamin C. 
  • Minerals- Minerals are an important constituent of our diet. Would you ever notice how TV commercials for lunch break cereal always mention nutritional vitamins and minerals? However, when you think of vitamins, food isn't the initial thing that occurs to you. Usually are minerals something you will find in the soil, like iron and quartz.Well, yes, but small amounts of some mineral deposits are also in foods - for instance, red meat, such as ground beef, is a good source of iron.Much like nutritional vitamins, minerals help your system expand, develop, and stay fit.The body uses nutrients to execute many different functions - from building strong bones to transmitting nerve system impulses. Some minerals are even used to make hormones or maintain a normal heartbeat. Some examples of minerals are calcium, phosphorus, sodium, chlorine, magnesium, potassium, and sulphur. 
B. Non-Nutritive Components of Diet 

Non-Nutritive components of the diet are those components of diet which do not provide us energy, calories, etc. Non-Nutritive components of the diet include roughage(fibre), water, colour, flavour, etc. They are added to for many reasons such as water is required to give correct texture to food or to cook it, colours are added to attract customers towards food, flavours are added to provide the right type of taste to food.  The explanation of Non-Nutritive components of diet are:diet which do not provide us energy, calories, etc. Non-Nutritive components of the diet include roughage(fibre), water, colour, flavour, etc. They are added to for many reasons such as water is required to give correct texture to food or to cook it, colours are added to attract customers towards food, flavours are added to provide the right type of taste to food.  The explanation of Non-Nutritive components of diet are:

  • Fibre or Roughage- Fibre or Roughage has no nutrient value. It is undigested part of the diet and cannot be digested by human intestinal tract. It helps individual to satisfy the appetite. It helps to repair and correct the disorders of the large intestine. It also prevents constipations and helps to reduce sugar levels in the blood. Sources of Fibre are wheat, fruits, root, vegetables, oats, connective tissues of meat and fish etc.
  • Water- Water is also a non-nutritive component of the diet. Water is used in food to cook or to provide suitable texture. It helps to regulate body temperature, it keeps our skin moist etc. It is excreted from our body in the form of urine, sweat, faeces and water vapours in the exhaled breath.
  • Colours- To make food more attractive , food colours are added to it. Natural colours are present in fruits and vegetables. Colours obtained from animal products and grains are less bright or dark in colour.
  • Flavour- Flavours are classified into 2 types: Natural flavours and Artificial flavours. Natural flavours are obtained from fruits, vegetables, animals etc while artificial flavours are those which are obtained from chemicals. Flavours are added to food to develop its taste . 
  • Plant compounds- Many different non-nutritive substances are commonly consumed in the daily diet. These include the beverages coffee and tea. They may be harmful to us if taken in excessive quantity. Excess of such products may lead to increase in heart rate, secretion of stomach acid and urination.

Eating Disorders- Anorexia Nervosa and Bulimia

Eating Disorders

When someone eats in an abnormal manner such as eating too less or eating too much , then it is called as eating disorders. In fact, eating disorders are the mental illness which affects regular diet of a person. Eating disorders affect mental as well as physical health of people. People who suffer from such disorders are found to be depressed and unhappy with their body shape or figure. Eating disorder may help them to reduce or gain weight fast but it also reduces the supply of nutrients to the body.

Causes of Anorexia Nervosa and Bulimia Nervosa (eating disorders)

1. Hormonal Imbalance- During puberty stage, the body undergoes various changes due to hormonal changes. If a person feels bad about those changes then there are chances that he/she may suffer from disorders like Anorexia or Bulimia.

2. Heredity- In various research and observations, it is found that Anorexia Nervosa can be transmitted from parents to the child. So it is also a possible that a person suffering from eating disorder received this disorder from parents.

3. Negative Body Image- Body image plays a vital role in eating disorders. If a person possesses a positive body image then there are fewer chances that he will suffer from  eating disorder.

  • Beauty comes in all sizes and shapes- It is not necessary that only slim figured people are liked and loved. Healthy people are also loved equally. Observations tell us that people who are healthy are liked by 65% of people, they meet in their life.
  • Have a healthy approach towards exercise and food- Instead of rewarding kids with extra food, family members should be a role model for them and inspire them for a healthy lifestyle.
  • Society- We should always remember that the people surrounding us, always affects our thoughts, so it is very important to understand symptoms of anorexia nervosa and with the help of them, changing our society.

Treatment of Anorexia Nervosa And Bulimia Nervosa. (Eating Disorders)

    The treatment of eating disorders is usually multidisciplinary which involves medical and psychological treatment. So the treatment is done by a physician, dietician and a psychologist. The treatment of eating disorders is very long and can take up to 1 year for full recovery. The treatment of eating disorders are listed below:
    • Psychological treatment- The root cause of eating disorders is psychological so it is recommended to take psychological treatments accordingly.
    • Medications- Medications include antidepressants which help us to balance chemicals in the brain and improving our mood.
    • Education about Nutrition and Healthy Weight- To prevent a person suffer again from eating disorders, proper knowledge about should be given to a person .
    • Be cautious about exercise- Healthcare provider should give a proper plan of physical activity or exercise to the person affected by bulimia. The affected person should not perform the excessive exercise to burn off calories consumed by taking more amount of food.

    Effects of diet on performance

    Any diet which has all the constituents of food. necessary for the maintenance and growth of body in sufficient amount is essential for all the individuals whether they perform simple work or engage in highly competitive sport. The requirement of diet varies from one person to other person depending upon their activities, size, weight etc. General requirement of an active person varies from 3000 calories to 8000 calories. It would be better to know the Effects of essential nutrients on performance:
    1. Fat- Fat works as a fuel for our body. Different types of sports require the different composition of fat to muscles for maximum performance. In sports like  running, cycling, high jumpers, gymnastics etc which require a high level of body movements require a minimum amount of fat. In sports such as sumo wrestling, maximum amount of fat is required. So the quantity of fat is different for different type of sports.
    2. Carbohydrates- Carbohydrates is also a fuel for our body. Carbohydrates should be given in medium amount. Excessive carbohydrate is converted to fat which is not good for the athlete. Low amount of carbohydrates usually results in exhaustion.
    3. Protein- Protein in a necessary component of diet which helps in growth and formation of tissues in the body. It is also used as a fuel in body but body prefers carbohydrate and fat as fuel when it comes to choosing between all three. Many sports leads to injury to tissues, in such sports, proteins are used in forms of supplements to heal the injury. Excessive protein causes weight gain, and sometimes cancer also.So it is very necessary to calculate the protein requirement before person starts taking it.
    4. Vitamins-  Vitamins are very important for a healthy life. Vitamins protect us from various types of diseases and also contribute to the growth of our body. There is no clear evidence that vitamins help to improve performance. The body cannot store excess vitamins and excessive vitamins are excreted through urine. various vitamins.
    5. Water- Water is an essential component of our life. Deficiency of water leads to decrease in performance but the excess of water also do not create any problem because water has no calorific value and it is excreted through urine.
    So, it can be seen that there is no significant effect of diet on our performance. Even the successful sportsperson also require a well-balanced diet to present a good performance in sports. A balanced diet is always considered essential for every sportsperson for a good performance in sports.
