Scientific analysis in swimming typically involves either 2D or 3D camera systems. Particularly for coaches, 3D camera systems present with limitations of considerable setup time and cost, which limits their general accessibility. Standard (2D) video technology has become easily accessible due to a general reduction in price, leading to regular use within by: 5. Discussing the effect of kinetics and kinematics on the efficiency of the front crawl.

  This is a video analysis for an age group triathlete who shows signs of the very typical errors that most swimmers make. She is considered a very good swimmer in . Material. The study involved 9 highly qualified crawl-stroke swimmers, members of Russia national team. The age of the participants ranged from 18 to 24 years. It is studied the kinematic and kinetic characteristics of the front crawl swimming technique of highly Author: A.I. Krylov, A.A. Gorelov, A.A. Tretyakov.

Freestyle Swimming Muscle Analysis 9 swimmer rotates his or her head varies, depending on the swimmers preference. However, when the swimmer uses cervical rotation, it is contralateral to the side of the arm that is extended forward in front of the head. The muscle used in this action is the Size: KB. III. Front Crawl. The arms contribute more to propulsion than the legs in front crawl swimming, with reports of up to 90%, but generally agreed at 85%7, 8, 9, In addition to this, the swimmer's arm motions, and the coordination of them, are of importance in relation to performance.

The purpose of this study was to describe and analyze, by kinematic techniques, selected movements of the trunk and upper extremity as displayed by world-class crawl stroke swimmers engaged in competition.

In her best-selling book Swim Speed Secrets, 4-time Olympian and gold medalist Sheila Taormina revealed the freestyle swimming technique used by the world's fastest swimmers.

Now in Swim Speed Strokes Taormina shows swimmers and triathletes how they can swim with elite technique in all four swimming strokes--butterfly, backstroke, breaststroke, and freestyle/5(82).

The Swimming Strokes Book is designed to break each stroke down into its component parts, those parts being body position, legs, arms, breathing and timing and coordination. An exercise or series of exercises are then assigned to that part along with relevant teaching points and technique tips, to help focus only on that stroke part.

Biomechanics of Competitive Swimming Strokes limb’s behavior. For instance, at Front Crawl, Deschodt et al.

As the upper limb’s velocity increased, the horizontal velocity of the swimmers increased as Size: KB.

We have chosen to place the sensor on the swimmer’s head, as for certain swimming styles, e.g. front crawl, the head angle. This study evaluated three-dimensional kinematic parameters of the front crawl stroke in physically impaired swimmers across a range of functional classification levels.

For example, the mean swimming velocity during 25 m of maximal breaststroke swimming was m s −1 for the two male and two female world-class competitive swimmers (Olstad et al., b), whereas the estimated swimming velocity during competition for 50 m breaststroke in accordance with the International Swimming Federation (FINA) point Author: Sohei Washino, Sohei Washino, Dean L.

Abstract The purpose of this study was to use three-dimensional methods to determine whether there are distinct kinematic differences between sprint and distance front crawl swimmers when swimming at a sprint pace.

Therefore we have set the following hypotheses for our front crawl research H1: Swimmers with a deeper stroke have a higher mean speed. H2: Swimmers with lower frequency of arm strokes have lower mean Size: 1MB.Differences between sprint and distance swimmers were assessed with an independent t-test for each variable, in addition to effect size calculations.

Differences between sprint and distance front crawl swimmers were generally small and not significant when swimming at a sprint pace.
