Introduction It is important for swimmers to possess excellent turning skills, especially in distance swimming. Freestyle swimmers spend 20 to 38% of their time turning in short-course races and improving turning can decrease race time by at least 0.20 s per length ( Maglischo, 2003 , Slawson et al., 2011). The most difficult process in turn training is diagnosis because the turn is complex (i.e., it contains different parts and must be completed within a brief period of time). A thorough analysis on turns and practice enabled Chinese Olympic champion Sun Yang to

Abstract

In this paper we wanted to demonstrate that improving swimming performance, even over a short period of time, requires a centralized training program. The subjects of the research were checked on a distance of 50m freestyle before and after the application of the centralized training program, and the results were compared with those from the control group who did not benefit from the centralized training program, the latter ones having participated only in the classes of the approved syllabus. All the results from the research were interpreted objectively, the resulting figures being the actual support of this study. The tests and the program applied proved relevant in view of the purpose of this study

Abstract

Swimming is a very important component of the military training. This can be proven by the fact that swimming is a beneficial sport for the human body because the joints are not tensed like in running, increases heart rate, but also stimulates blood circulation. At the same time, while swimming, absolutely all muscle groups are involved, which means automatically shaping them and, over time, increasing the body’s resistance.

The study found the following:

• students’ results at the 50 m freestyle swimming test are positively influenced if an additional training program is respected;

• additional physical training leads to improved performance.

sample was 709.6 ± 71.1. All participants were informed of the procedures to be utilized and signed a written informed consent form prior to investigation. For swimmers under 18 years old, consent was obtained from their legal guardians. The study protocol adhered to the tenets of the Declaration of Helsinki and was approved by the University of Granada Institutional Review Board. Study design A correlation study was designed to examine the relationship between different dry land strength and power tests and freestyle track start performance (times to 5, 10 and 15 m

Summary

The start and the turn are factors that influence performance in different swimming disciplines. The aim of this study was to find out the relationship of selected time parameters of the start and the turn with sport performance of 100 m and 1 500 m freestyle finalists in the Olympic Games 2016. Monitored parameters of the start were the start reaction, time under water after the start, and time at a distance of 15 m after the start. The monitored parameters of the turn were the time of 5 m before the turn, the duration of the turn, the time under water after the turn, and time reached at a distance of 15 m after the turn. There was any significant correlation of the resulting time to 1 500 m and the observed start indicators. The significant correlation of the resulting time to 1 500 m and the observed turn indicators was time 5 m before the turn r = 0.952 (p = 0.000); the duration of the turn r = 0.830 (p = 0.011); time at a distance of 15 m after the turn r = 0.886 (p = 0.003). The significant correlation of the resulting time to 100 m and the observed start indicators was time under water after the start r = −0.714 (p = 0.047). The significant correlation of the resulting time to 100 m and the observed turn indicators was the duration of the turn was r = 0.905 (p = 0.002). The results point out the existing relations between 100 m freestyle and time under water after start and duration of the turn. And for 1 500 m existing relations with time 5 m before the turn, the duration of the turn and time at a distance of 15 m after the turn. Therefore, our recommendations for sports practice include development of speed, power and coordination skills with technical execution of the start and the turn into regular swimming training.

of male 50 m freestyle swimmers in a local championship ( Hlavaty, 2010 ). Finally, focusing on the evolution of size and shape in swimming, Charles and Bejan (2008) analyzed the data of men’s world records for 100 m freestyle from 1912 to 2009 revealing proportionality between body height and speed. The aim of the present study was to evaluate in a much broader context the relationship between body height and performance in elite swimmers by means of data from men and women medalists in 50 and 100 m freestyle swimming.
