This blog comes from our colleague Jeff Overholt, Co-Founder of Golf Performance Coaches and PGA of Ontario 2013 Coach of the Year. This entry was initially published on the Golf Performance Coaches' blog under the title of "'Growing Up' - Acorns Becoming Oak Trees". Please visit their site for more excellent junior athlete development information.
Can you guess which of these junior golfers is the oldest? Which player would have an advantage if they were all competing on a golf course which was around 5500 yards?
Believe it or not the player on the left is actually the youngest (chronological age), but he is the oldest from a development age standpoint. Developmental age refers to the child’s age of physical, mental, emotional or intellectual maturity as opposed to chronological age, which represents the number of years and days which have elapsed since birth.
These concepts are very important for coaches and parents to understand if they have athletes of any sport between 10 – 15 years of age. During this time, children typically go through their growth spurt and hit a critical marker in their development called Peak Height Velocity (PHV).
