This paper analyses the dynamics of changes between the performances of elite freestyle swimmers recorded at particular Olympic Games. It also uses a set of chronologically ordered results to predict probable times of swimmers at the 2012 Olympic Games in London. The analysis of past performances of freestyle swimmers and their prediction have revealed a(More)
PURPOSE The main purpose of this study was to analyze the coordination, propulsion and non-propulsion phases in the 100 meter breaststroke race. METHODS Twenty-seven male swimmers (15.7 ± 1.98 years old) with the total body length (TBL) of 247.0 ± 10.60 [cm] performed an all-out 100 m breaststroke bout. The bouts were recorded with an underwater camera(More)
The breaststroke kick is responsible for a considerable portion of the forward propulsion in breaststroke swimming. The aim of this study was to measure selected anthropometric variables and functional properties of a swimmer's body: length of body parts; functional range of motion in the leg joints and anaerobic power of the lower limbs. Chosen kinematic(More)
It is possible to plan an altitude training (AT) period in such a way that the enhanced physical endurance obtained as a result of adaptation to hypoxia will appear and can be used to improve performance in competition. Yet finding rationales for usage of AT in highly trained swimmers is problematic. In practice AT, in its various forms, is still(More)
Purpose. The authors tried to point out the crucial factors determining swimming results in a 2000m front crawl race. Basic procedures. Two groups of subjects: G1 (16.8 ± 0.77 years) and G2 (14.7 ± 0.49 years) of 15 swimmers each took part in two incremental tests for assessing aerobic endurance of arms in arm cranking (V̇O 2max AR) and of legs in cycling(More)
OBJECTIVES this study, conducted in two male age groups, was aimed at analysing the influence of body properties, dry-land strength and swimming strength on 50 m crawl (VCrawl). METHODS We examined two competitive groups, Youth (20.6 ± 1.05), and Junior, (17.3 ± 0.59), through: a. (lean) body mass (BM and LBM), (total) body height (BH and TBL) and arm(More)
Freediving is a sport in which athletes aim to achieve the longest or the deepest breath-hold dive. Divers are at risk of gradually increasing hypoxia and hypercapnia due to a long time spent underwater and additionally of increasing hyperoxia while depth diving. Exceeding the limits of hypoxia endurance leads to loss of consciousness or even to death(More)
BACKGROUND This work is aimed at examining how coordination and kinematic indices interplay with swimming performance measured by average speed in 50m all-out test. METHODS The group of 34 male competitive swimmers (19.1± 1.91 years old) participated in the study. The underwater movements of swimmers' bodies were recorded providing side- shots.(More)
