The aim of the present study was two-fold: (i) to analyze progression and variability swimming performance (from entry times best performances) in 50, 100, 200 m at most recent FINA World Championships (ii) compare Top16, semifinalists, finalists between all rounds. Swimmers who qualified with A B standards for Budapest 2022 were considered. total 1102 individual performances swimmers analyzed ...

Detecting humans and classifying their activities on the water has significant applications for surveillance, border patrols, and rescue operations. When humans are illuminated by radar signal, they produce micro-Doppler signatures due to moving limbs. There has been a number of research into recognizing humans on land by their unique micro-Doppler signatures, but there is scant research into d...

purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

Wearable inertial and magnetic measurement units (IMMUs) have recently gained much attention in investigations approaching human kinematic analysis in sports scenario. Running, tennis, baseball, snowboarding, rowing, and swimming are some examples of sports already approached. In swimming, many studies proposed several methods to identify the temporal phases of a single swimming stroke or the s...

This paper presents a method for detecting swimmers in swimming pool. A vision based system for locating individual swimmers and recognizing the activities demands accurate detection of swimmer’s body parts such as head and limbs. Swimmer detection can be regarded as a background subtraction problem, which is very difficult due to a dynamic background with ripples, splashes, specular reflection...

Performance trends in breaststroke swimmers competing at world class level in pool competitions are well investigated for elite swimmers, but not for age group swimmers. This study investigated trends in participation, performance and sex difference in performance in a total of 35,143 (16,160 women and 18,983 men) age group breaststroke swimmers aged 25-29 to 95-99 years competing in the Fédéra...

Abstract Study aim : Determination of changes in thrust force and effect size training load swimmers using four swimming strokes monitored 4 times a year. Material methods Five elite male were examined macrocycle 9 months. The times: at baseline (September), immediately after the winter Polish Championships (December), end transition period (March), summer (late May). Results In all participant...
