Depending on a sport (sometimes position in a team) - height may play more or less of a role.
For example, on average - Basketball players are Tall, whereas Marathon runners tend to be short.
For sure, genetic attributes do not determine results - in many cases, height or specific body type
creates initial advantage. Consider boxing, taekwondo or fencing - in these cases reach (wingspan)
may serve as advantage and the reach is usually proportional to one's height. So, all in all,
height does create some level of advantage having a longer range of attack.
In this article though, we'll take a look on people who stand away from average height for their sport
and yet, they were able to achieve considerable results.
In basketball, on average players are tall. The height usually makes it easier to start. As for example, think of vertical jump and two persons of different height without specific training - a taller person will most of the time outperform a shorter one.
Dawn Staley is listed at 168 cm (5'6") and yet she got considerable achievements. Dawn is also a successful coach since 2000. Her highlights during career as a WNBA player (1999 - 2006) - include:
Allen Ezail Iverson is 183 cm (6'0") tall. That might be considered above average for general population, however in Basketball it is far from mathematical mean. That fact could not hold him down, Iverson player professionally during 1996-2011 and as a result:
In athletics (sprint in particular) the height question comes a little tricky - as Taller does not equal better. Instead, there seem to be a golden ratio at which person should be strong enough to get maximum speed, but not too tall to have optimal speed-to-weight ratio for good acceleration. The height range for sprinters tends to be around 175 cm (5'9") and 188 cm (6'2"). On top of that, a discussion goes, that shorter ones often do better on 100-race, whereas taller ones perform better on 800 distance.
Despite the introduction above, there is Usain St. Leo Bolt, 195 cm (6'5"), who has been dominating Olympic games since 2008. Achievement list includes:
Gymnasts are on a shorter side of a scale. Usually, explanation for that goes as follow - shorter individual has lower center of mass, which provides better balance and easier time to perform rotation moves (e.g. front flip).
Svetlana Vasilyevna Khorkina is listed at 165 cm (5'5"). However, for an average gymnast that can be considered as tall. For example, Carly Patterson (2004 Olympics gold) is only 152cm (5'0"). Despite unusual height for the sport, Svetlana collected considerable amount of Olympic and World championship medals:
Same story goes for male gymnast Alexei Yuryevich Nemov. Alexei is 173cm (5'8") tall participated in 1996, 2000, 2004 Olympics. His results contain:
