Children aged between 5 and 12 years are in their most productive and responsive period of movement learning. This is known as the ‘skill-hungry’ period and is the ideal time to further challenge the ever-growing muscular-skeletal system. Many of the limitations seen in the teen-age and senior years are traced back to this important period of a child’s development. It is during this period that the child will encounter the start of their growth spurt and so it is important to begin the process of movement learning and progression as soon as possible. All future sports-specific actions e.g. running, jumping, throwing, kicking, catching and striking begin their journey here. If there is any intention of trying to achieve sporting excellence in later years this is THE period within which to start the process towards movement efficiency. Without movement efficiency NOW there will be problems later. There is much evidence linking physical activity and physical literacy to improved academic achievement so the 5in5 can act as a catalyst to learning.
