Improving Children’s Physical Development and Performance
In recent years, the strength and performance of children have been changing for the better. This phenomenon is largely due to improvements in the social environment, such as nutrition and quality of living. This notwithstanding, a worrying trend is the increase observed in the number of overweight children, which is detrimental to the enjoyment of sport. It is all the more important, therefore, to pay attention to the nutrition and healthcare of children playing volleyball. Regarding the strength and performance of children, very few differences exist when one compares boys and girls between the ages of 10 and 12. These findings would tend to suggest that the same rules of mini-volleyball can be used for both genders.

More generally, the physical performance in humans consists of five elements: muscular strength, agility, general endurance, flexibility, and body control abilities. Of these, body control abilities such as timing, rhythm, balance, feeling of direction, concentration, and relaxation start to develop first. Figure 1 depicts the increase in human brain weight by age. As can be seen, the nerve centres controlling perception and movement develop rapidly up to the age of 8. Figure 2 shows that reaction times improve particularly between the ages of 8 and 15, when children are in primary or junior high school.

These data underscore the fact that consistent and well-planned coaching is necessary to achieve body control and attain ideal fitness in volleyball. The most suitable time for players to develop these athletic and body control abilities is when they are young. If incorrect movement patterns are learned, considerable effort is required to correct them subsequently. This means that mini-volleyball coaches must carefully study the basic techniques of volleyball so they can modify wrong patterns or bad habits.
