Motor Development – Children and Sports

Motor development only happens when the child is biologically and mentally ready for it. Motor development refers to the development of movement and various motor abilities from birth till death. It is the ability to move around and manipulate his/her environment. There are four stages of motor development in children

  1. Infanthood (0-2 years)
  2. Early childhood (2-6 years)
  3. Middle childhood (7-12 years)
  4. Later childhood (12 years and later)

The first stage is marked by extremely rapid growth and development, as is the second stage. By the age of 2 years, this development has begun to level out somewhat. The final stage does not have any marked new development; rather it is characterised by the mastering and development of the skills achieved in the first two stages. Before the stages of childhood, there is the age of infancy that is from 0-2 years.

Types of Motor Development

There are two types of motor development/skills

  1. Gross Motor Development This development uses the larger muscles of the skeleton or groups of larger muscles to maintain posture and balance for activities such as throwing a ball, walking, running and hopping.
  2. Fine Motor Development This development uses the smaller muscles of the hand, feet and face for more precise activities such as eating, speaking, playing with toys and eventually writing.

Factors that Influence Motor Development – Children and Sports

The development and quality of a child’s motor skills are influenced by many factors. These include

  1. Tone It refers to the ongoing contraction and state of the muscle at rest. Tone can be normal, hypotonic or hypertonic.
  2. Strength It refers to the force of a muscle contraction purposefully exerted against resistance to carry out an activity.
  3. Endurance This is the ability to maintain the exertion required for an activity.
  4. Motor Planning It is the complex and often intuitive ability to know how to carry out the steps needed to complete a physical, activity.
  5. Sensory Integration It is the ability to accurately interpret sensory input from the environment and to produce an appropriate motor response.

Exercise Guidelines at Different Stages of Growth and Development

The motor development in children takes place in various stages of growth. The infanthood or infancy is followed by the childhood, stage that is divided into three stages : the early, middle and later childhood.

Infanthood (0-12 Months)

  • Turns head.
  • Moves arms and legs.
  • Reaches and grasps objects.
  • Rolls back from side to side.
  • Crawls, stands and walks.

Childhood (2-12 Years)
2-5 Years (Early Childhood)

  • Basic locomotor.
  • Ball-handling.
  • Eye-hand coordination.
  • Running, jumping, hopping, skipping grasping.
  • Games with-simple rules.

6-10 Years (Middle Childhood)

  • Fine motor skills.
  • Fine eye-hand coordination.
  • Growth is relatively slow.
  • Cognitive activities.
  • Movement precision.
  • Balancing and coordination.
  • Catching, throwing; kicking.
  • Planned activities games.

11-12 Years (Late Childhood)

Motor skills perfected.
Onset of puberty.
Beginning of sexual maturation.
Planned activities, that involve a .lot of movements.

Weight Training

Weight training refers to the physical exercise which involves lifting weights to improve the” performance of the muscles. Weight training-for children carries with it a variety of advantages.

  • It builds muscle strength and strong bones.
  • It reduces excess, body weight.
  • It boosts confidence.
  • It makes a child more competitive.

Disadvantages of weight training are as follows

Serious injuries have come from situations with home gym equipment when there was no supervision.
Another disadvantage is the risk of non-flexibility. This happens when proper exercise to. increase flexibility is not done along with weight training. If weight training is combined with flexibility exercises then this problem will not occur.

Concept of Correct Posture

Correct posture is one in which the body is so balanced as to produce least fatigue. It means that correct posture is the position of the body held without any sense of effort. The body weight should be equally distributed over both the legs and feet so as to produce least fatigue. Correct posture may also be defined as that assumed position which enables the body to perform or function effectively.
These are stated below

1. Correct Posture of Standing In standing position, both the heels of the feet should meet each other. The whole body should be erect, knees straight, chin inside, chest forward, belly backward and pressed inside with equal body weight on both feet. In this position, the complete body should be balanced.

2. Correct Posture of Sitting When we sit in a chair, our hips should be in a straight line and erect. Legs should touch the ground and should not be in hanging position. Thighs should be in horizontal position. The backbone should be erect with the upper region of the backbone straight against the back of the chair. While we read, the book should be on the table but the book should not be too away or too near the eyes. The approximate distance between book and eyes should be at least 30 cms. For writing, a table with slight inclination towards the outside is appropriate.

Advantages of Correct Posture

Advantages of correct posture are as follows

  1. Improves Physical Appearance A good posture helps in creating a good impression and improves the physical appearance. This in turn helps in building an impressive personality.
  2. Have more Energy Good posture ensures greater energy as the mind and body work in coordination with each other. More energy means more capacity to work and perform tasks.
  3. Increases Flexibility Good posture ensures proper alignment of the body as well as balanced approach. This increases the flexibility of the body as bones and muscles remain well toned.
  4. Reduces Muscle Tension Good posture does not put excess pressure on a particular muscle. Therefore the muscles remain in their normal position. Neither it brings stiffness to any part of the body so there is no tightening of the muscles.
  5. Increases Confidence An upright and relaxed posture increases strength and power of a person. This helps the individual to sit or stand upright which brings in confidence.

Causes of Bad Posture

Poor posture is the posture that results from certain muscles tightening up or shortening. There are different factors which can impact on posture. Some common causes for bad posture are given below

  1. Pain or Past Injuries In order to avoid the pain in the body such as back pain or simply to avoid pain from past injuries, people try to overcome the pain by holding the body in a different position. When this posture is continued for a long time, it can become a daily habit. Hence holding yourself differently can be due to some pain or muscle injury in any part of your body.
  2. Low Nutrition Low nutrition and lack of vitamins and calcium in the diet can affect the bones and muscles by not providing adequate strength and flexibility to hold your body in a correct posture.
  3. Hereditary Reasons Having a family history of bent back or flat foot, may cause bad posture. The genes may be responsible for poor posture.
  4. Overweight and Obesity Extra body weight can also be the reason for poor posture. Obese and overweight people tend to collect excess fat around their stomach and hips. This puts strain on the skeletal system as well as muscles thereby resulting in poor posture.
  5. Habit Sometimes, the way you walk or . the way you hold things can be the reason of bad posture. For instance, if you always walk with your head down or slump your shoulders, this can cause your posture to pull out from proper alignment. Sometimes, carrying weight on only one side of the body can contribute to imbalanced or poor posture. This is especially true for children who carry heavy bags to school on one side of their body, as the bones are soft at this age. .
  6. Type of Job People who have desk jobs often push their neck and head forward and hunch their shoulders. All these factors contribute to our inability to keep our spines straight and results in – poor posture.
  7. Lifestyle and Fashion Clothing and shoes especially affect posture. Women who walk in pencil heels are more prone to cause problems to their posture. Besides high heeled shoes, wearing boots, tight fitting clothes, low waist jeans and wide belts can cause bad posture. This changes your centre of gravity, which ultimately causes your posture to suffer.

Common Postural Deformities

This refers to the deformation in the skeletal structure or where the body parts are not aligned that results in some kind of postural deformities. People having postural deformities cannot perform their work efficiently. Some common postural deformities are Knock Knee, Flat Foot, Round Shoulders, Lordosis, Kyphosis, Bow Legs and Scoliosis.
