Physiological predictors of flat-water kayak performance in women

Abstract

This study was conducted to investigate the relationship between selected physiological variables and 500-m flat-water kayak (K500) performance. Nine female, high-performance kayak paddlers, mean (SD) age 23 (5) years, participated in this investigation. Testing was conducted over 6 days and included anthropometric measurements (height, body mass and skinfolds), an incremental test to determine both peak VO2 and the "anaerobic threshold" (Th(an)), and a 2-min, all-out test to calculate accumulated oxygen deficit (AOD). Blood lactate concentrations were measured during the incremental test and at the completion of both tests. Subjects also completed a K500 race under competition conditions. K500 time was significantly correlated with both peak VO2 (r = -0.82, P < 0.05) and the power output achieved at the end of the incremental test (r = -0.75, P < 0.05). However, the variable most strongly correlated with K500 time was Th(an) (r = -0.89, P < 0.05). A stepwise multiple regression, for which r = 0.95 and the standard error of estimate = 1.6 s, yielded the following equation: K500time(s) = 160.6-0.154 x AOD x kg(-1) - 0.250 x Th(an). In conclusion, the results of this study have demonstrated that although K500 performance is a predominantly aerobic activity, it does require a large anaerobic contribution. The importance of both the aerobic and anaerobic energy systems is reflected by the K500 time being best predicted by a linear combination of Th(an) and AOD x kg(-1). This suggests the need to develop and implement training programmes that develop optimally both of these physiological attributes. Further research is required to elucidate the most effective means by which to develop both the aerobic and anaerobic energy systems.

Análise da cinética de remoção de lactato em atletas de canoagem slalom

“…Os mesmos autores realizaram estudo semelhante com nove canoístas de velocidade do sexo feminino de alto nível competitivo com desempenho em kayak ergômetro por 2 minutos. Os resultados demonstraram alta correlação entre o desempenho total no teste de K 500 e VO 2 pico (r= 0.82; P<0.05) e limiar anaeróbico (r=0.89; P<0.05) (BISHOP et al, 2000b). Resultados similares foram encontrados por Franchini et al (2009) com lutadores de judô.…”

“…Estudos indicam que atletas desta modalidade dispõem de valores elevados de capacidade anaeróbia e força muscular de membros superiores (BISHOP, 2000a;NAKAMURA et al, 2006;AKCA;MUNIROUGLU, 2008;MICHAEL et al, 2009;IZQUIERDO, 2011). Os atletas, além de dispor, na maior parte do tempo, de treinamento para aperfeiçoamento da técnica, também enfatizam adaptações de ordem cardiorrespiratória e neuromusculares, buscando o desenvolvimento da capacidade oxidativa, além de potência muscular de membros superiores (KEARNEY;MCKINSEY, 2000;BISHOP, 2000a;ZAMPARO et al, 2006;GARCÍA-PALLARÉS et al, 2009;IZQUIERDO, 2011).…”

Training Of Young Female Kayak Sprint Rowers in Yearly Cycle and Changes of Their Physical and Functional Capacities

“…Nuolatos didėjanti konkurencija pasaulio baidarių ir kanojų irklavimo varžybų vandens takeliuose įrodo, kad jaunųjų baidarininkių ugdymas priklauso nuo daugelio veiksnių, iš kurių svarbiausias yra treniruotės vyksmo kryptingumas, jo valdymas, atsižvelgiant į sportininkių organizmo adaptacijos prie treniruotės ir varžybų krūvių individualius ypatumus (Nedari, 1998;Bishop, 2000).…”

“…Moterų baidarininkių rengimą atskirais aspektais tyrinėjo D. Bishop (2000), A. Alekrinskis ir kt. (2013), tačiau Lietuvos jaunųjų baidarininkių rengimo, jų fizinių ir funkcinių galių kaitos metiniu ciklu problemas nagrinėjančių tyrimų dar nepakanka.…”
