Size matters

It does make a physical difference how tall a swimmer is.

Taking a 50 m pool and assuming that a 150cm tall swimmer achieves propelling forward by half the body length and assuming that in the 3 strokes of freestyle, backstroke or butterfly a swimmer reaches the water surface after 10 m during the start it takes the 150cm tall swimmer 17.78 strokes to reach the end of the pool.

Assuming that a 180cm tall swimmers swims in a 50m pool and assuming that this taller swimmer comes up at 15m after the starting jump it takes the 180 cm tall swimmer 12.97 strokes to reach the end of the pool.

That is assuming that both swimmers have the same stroke efficiency. Hence we see that in most sprint events at the major international competitions the taller swimmers seem to dominate at the short distances.

Katinka Hosszu

I did not include breaststroke into the calculation because there is no rule that a swimmer has to surface after 15m neither at the start or after a turn, meaning that efficient kicking during the under-water phase can propel a swimmer half-way across the pool.

Yet it is quite interesting that in disciplines like the Individual Medley, we see it time and time again that those swimmers who are most proficient at the breaststroke also win the whole race that consists of a combination of all four strokes.

MCASA Development silver

The medals are getting prettier, this MCASA silver medal is one of the nicest in appearance, tucked into a smart case with wonderful decorations.

MCASA silver medal

Won at the Middlesex Winter Development meet on 15. October 2017.

It is Madison’s first medal won whilst swimming for Hackney Aquatics.

@gllsf, @HackneyAquatics

Madison was very brave to attend this competition because she sprained her wrist 3 days before and had lots of ice packs. Of course she was slower than her PB and could not improve her speed but still maintained the competitive spirit.

400 IM Mireia Belmonte SC record

Mireia managed to overturn Katinka Hosszu’s 400 IM short-course record recently. As shown in the video

Mareia’ great breaststroke term manged to achieve this new world record. But looking at the preceding fly and backstroke legs, if a swimmer would be perfect in all 4 strokes the 400IM world record could still be faster.

Quite often in IM the breaststroke is the deciding leg.

Katinka Hosszu was considerably ahead in the fly and then especially the backstroke and could not even overturn Mareia’s breaststroke lead in the final front crawl leg.

Belmonte set a new 400 IM WR of 4:18.94 at the SC Worldcup in Eindhoven. That eclipses the previous record held by Hungary’s Katinka Hosszu of 4:19.46 set at the 2015 European Short Course Championships.

Usually I think swimmers are either good in the stretchy strokes or the breaststroke but Mareia’s freestyle was equally as good as her breaststroke and so her breaststroke advances could not be overturned by Katinka in the final leg.
