I am writing all those who are not the tallest to stick to swimming.
looking at boxing as a sport and we see different classes of boxers, according to their weight, they can fight an equal partner. But then in boxing, each fight accumulates significant revenues and it is therefore profitable.
Swimming is not such a money raker, though lately, the increasingly impressive bodies and nice personalities of top swimmers, especially Adam Peaty, attract more viewers, now that the healthy body image is on the top of the agenda for many
I think it is because of financial considerations that swimming is merely portioned into age-groups. A big breakthrough lately has been a further distinction into able and various ability groups. Though if swimming was further portioned into height, then the swimming competitors would take considerably longer to process and already there are shortages of officials as it is in the average level 3 age-group competitions.
Though, when looking at swimming results I now straightaway, go to the swimmer’s Wikipedia page and see how high they are. I am always very relieved when I see that the tallest didn’t win.
The latest victory of Pellegrini in the 200 free for example, see Swimmingworld article, shows her not to be the tallest out of Katie Ledecky and McKeon, she is however only very marginally shorter than both.
The most significant height difference could be seen in the German Frankziska Hentke who won the prelims heat and gotten the silver in the finals of the World Championships in Budapest 2017. See FINA review.
I would say that it often depends on the kind of stroke, whether shorter physical height can achieve.
Katinka Hosszu who currently holds the most world records for women is a mere 175cm.
I’ve also come across Katie Matts who was considerably shorter than her fellow competitors but won the British Champs 2 times in a row. Picture here on a podium in a different race where she won bronze, just to show the relative height. I am unable to find an article with her body height in it.
Last year, using the typical height charts I calculated Madison’s ultimate body height to become 175-78 but now I am not so sure. I think that height might play a big factor in how much one invests into the sport because the more time you invest the less time you have to do anything else.
I feel that endurance and bodybuilding can out-swim height and sprint ability in especially the 200m races in Butterfly and Breaststroke.
There is no need to be obsessive about height because the ultimate power of decision-making is with the swimmer and if the swimmer thinks they can win, they will want to try their hardest. Especially if swimming as sport increases the happiness factor of a swimmer and aids with learning there is no question that every length spent in the pool is time well spent.
Especially when Madison was younger and she was put into a fast heat, despite being so young, she always complaint, that everybody else was much taller than her. I think a swimmer learns to overcome certain fears and deal with it in a positive way.
But Hannah Miley must be an inspiration to anybody who is not very tall, she is a very fierce swimmer and full of winning energy.
