The following collage of sequences from some of the world's best backstrokers are presented as teaching aids in Dr. Rushall's Stroke Clinics. Each item is presented to show important features of the stroke that should be adapted to each individual's capabilities.

The time between each frame is not known (this analysis is from a slow motion clip). Because of the quality of the video, it is only possible to view Jodie Henry's right arm pull. Jodie Henry's time for this event was 53.84 seconds.

This stroke analysis includes a moving sequence in real time, a moving sequence where each frame is displayed for .5 of a second, and still frames.

The time between each frame is .1 seconds. Libby Lenton did not swim the 200-m freestyle individual event at the Australian Trials or the World Championships. The reason she is featured here is that this swim, the lead-off leg for Australia in the 4 x 200 m freestyle relay, was timed at 1:57.06, the fastest time in the world in 2005 and faster than Solonne Figues' time of 1:58.6 in winning the individual event at the World Championships. Libby Lenton established herself as the premier women's sprinter of 2005.

Each frame is .1 seconds apart. Inge De Bruijn's time for this event was 53.83 seconds. This series is offered purely because the standard of visual is slightly better than other analyses from this side.

The time between each frame is not known. Hannah-Maria Seppala's time for this race was 54.37.

안녕하세요,

수영 훈련 할 때 풀 훈련시 자주 사용하는 풀보이를 아주 쉽게 제작하였습니다.

만들어 보니 양산된 제품보단 만족도가 높습니다.

그리고 제품을 만들게 된 이유는 일반적으로 수영장에서 많이 사용하는 일명 땅꽁 풀보이는 허벅지에 사용되지만, 저같은 경우는 발목에 착용을 하기위해서 만들어봤습니다. 일반 땅꽁 풀보이로 발목에 사용하니 힘들더라구요.

안녕하세요, KSCA회원 coachhoon입니다.

시중에 판매하고 있는 훈련용 LED시계는 가격이 부담되어 시간을 짬내어 만들어 봤습니다.

현재 선수들 훈련을 할때 가시거리가 좋아 25m거리에서도 잘보입니다.(제 시력은 0.6정도 됩니다.)

다들 가격때문에 부담되었던 훈련용 LED시계를 직접 만들어보는것도 어렵게 생각이 들지만, 그렇지 않습니다. 해볼만합니다.

The respiratory system is not typically associated as the limiting factor in maximal exercise, and the influence of inspiratory (breathing inward) muscle fatigue during maximal exercise is unclear. Studies suggest long and short duration high intensity exercise causes inspiratory muscle fatigue leading to impaired performance. Breathing during swimming is especially important since breathing frequency is less compared to land sports.

What do athletes competing in the following sports have in common Swimming, rowing, synchronized swimming, shot putting, tennis, karate, archery, discus, weight lifting, paddling, shooting and many others.

Stroke rate and length are two essential players in swimming speed. These two factors play a HUGE role in every stroke, but their impact on swimming velocity is still unknown. Some have gone as far as stating, swimming velocity is the product of stroke length and stroke rate.

Ice baths and cold water baths (cyrotherapy) are commonly seen in sports medicine. From experience, ice baths are cold…obviously, but after a few minutes you are able to relax. At the Beijing Olympics ice baths were frequently used with swimmers, but do ice baths really work and how do they work? Ice baths are proposed to help the athlete recover faster, reduce pain/soreness, and prevent injuries, but what does the literature indicate.

ScienceDaily (Jan. 19, 2007) Swimmers and scuba divers can improve their swimming endurance and breathing capacity through targeted training of the respiratory muscles, researchers at the University at Buffalo have shown.

All endurance athletes are familiar with the term VO2 or VO2max. We know elite endurance athletes have high VO2max, whether it is Lance Armstrong (84 mL/kg/min) or Steve Prefontaine (84.4 mL/kg/min). VO2max is the maximal amount of oxygen in liters the body can transport and utilize during exercise. Swimmers VO2max can be assessed outside the pool (running/biking), but performing this test with a different stimulus can stress the body providing invalid results.
