1. Heredity:

The genes that we get from our parents are responsible for motor development.
The percentage of fast twitch muscle fibers and slow twitch muscle fibers depends
upon biological factors. These factors affect the rate and ability of motor
development.

2. Environmental factors

Clean, safe and natural environment is healthy and good for motor development
activities.

3. Nutritional factors:
Nutritious food promotes good motor development.
Children become stronger and healthy with good diet that improves motor
development.

4. Physical activities:
Performing regular physical activities or exercise, enhances motor development at
faster rate in children.

5. Obesity:
Obesity and overweight have negative effect on motor development.

Obese and overweight children have less motor development whereas healthy child has
more skill perfection or good motor development.

6. Postural deformity:
Postural deformities also have negative effects on motor development.
It reduces perfection and accuracy in motor skills whereas a healthy person gains
faster motor development.

7. Opportunities:

Children should get ample opportunities to do more and more physical activities or
motor activities. Opportunities to participate in motor activities give a better chance
for developing sensory motor abilities.

8. Sensory Impairment:
Sensory Impairment such as visual impairments, hearing impairments, etc. are like
to affect the motor development in children.
