Physiological factors to predict on traditional rowing performance

Abstract

The purpose of this study was to determine the best prediction factors of traditional rowing performance in traditional elite (ER) and amateur (AR) rowers. Average power during the 20-min all-out test (W(20 min)), average power output which elicited a blood lactate concentration of 4 mmol l(-1) (W(4 mmol l(-1))), power output in 10 maximal strokes (W(10 strokes)), maximal strength and muscle power output during a bench pull (BP) and anthropometric values were all measured for 46 trained male rowers aged 21-30 with 8-15 years of rowing training experience. The ER group showed greater body mass (5%, p < 0.05), greater fat free body mass (5%, p < 0.05), greater 1RM(BP) (13%, p < 0.001), longer training experience (43%, p < 0.001), and a shorter time in the 2,000 m test (4%, p < 0.05) than the AR group. The ER group showed higher power output values in W(10 strokes) (9%, p < 0.01), W(20 min) (15.4%, p < 0.01) and (W(4 mmol l(-1))) (17.8%, p < 0.01) compared with the AR group. Significant relationships were observed between (W(4 mmol l(-1))) and W(20 min) (r = 0.65 and 0.80; p < 0.01 in ER and AR, respectively). The indices for rowing performance suggested that W(20 min), (W(4 mmol l(-1))), W(10 strokes) and 1RM(BP) were the most important predictors of traditional rowing performance in elite and amateur rowers.

Predição Do Desempenho a Partir Das Características Antropométricas, Fisiológicas E De Força No Remo

“…O estudo de Izquierdo-Gabarren et al 8 avaliaram fatores fisioló-gicos preditores do desempenho e também encontraram correlação significativa entre massa magra e desempenho no remoergômetro. Em outro estudo 1 aonde foram avaliados os preditores de desempenho, os autores encontraram forte correlação entre a massa magra (r=-0,812; p<0,01), a estatura (r=-0,801; p<0,01), o agachamento 1RM (r=-0,755; p<0,01), a envergadura (r=-0,715; p<0,01) e potência média (r=-0,796; p<0,01) com o desempenho no remoergômetro, propondo que essas variáveis podem predizer o desempenho, assim como os dados apontados no presente estudo.…”

“…Com a avaliação individual do remador, os técnicos são capazes de avaliar o ranking de cada atleta na equipe em ambiente controlado 1 . Assim, os resultados das avaliações de potência e força máxima são preditores de desempenho no remoergômetro no teste máximo de 2000 metros [8][9][10][11] . Além disso, o comportamento físico está relacionado com a composição e dimensão corporal do remador de alto nível, por serem fatores determinantes da força muscular e amplitude de movimento nas fases da remada 12,13 .…”

The use of Neuro Emotional Technique with competitive rowers: A case series

“…The 2000m ergometer time trial is recommended, which has demonstrated excellent test-retest reliability, 39,40 and which is thought to better correlate with actual rowing performance. 38,41 Other assessment measures that future researchers may want to consider as an alternative to the Max Power Test are the 1-rep-max (1RM) leg press, a measure of lower body strength, 9 or the vertical jump, a measure of lower body power. 6,30 Another limitation of this study is that other factors that may impact performance were not monitored, such as caffeine consumption 42 and menstruation.…”

“…6 Prior research has shown that the single best predictor of rowing performance is bilateral leg power. [6][7][8][9][10] Moreover, optimal rowing performance requires a consistent power output over time. 4 Since muscular power is the application of force (i.e.…”

“…Traditionally, resistance training is used to develop strength; however, recent studies have shown that concurrent resistance and endurance training may compromise gains in strength and power. 9,12,13 Therefore, an alternative method of optimizing consistent power output would be beneficial.…”
