Abstract

Aim of this study was to identify the physical and strength profile of Indian elite rowers categorically and finding relation of those variables with rowing performance. The study also aimed to develop rowing performance predicting different regression models to specify their essential performance limiting elements that could be used to maximize performance. To fulfill the research purpose, 139 light weight category and 60 open category elite male rowers with more than five years of rowing experience were evaluated. Height, weight, skin caliper, sliding caliper and strength dynamometer, respectively. Body fat percentage was calculated with Siri's equation and somatotype using Heath-Carter formula. A 2000m rowing test was conducted on a rowing ergometer. Results showed higher body weight (10.3%,p<0.0001), height (1.9%,p<0.0001), age (8.2%,p<0.01), body fat percentage (18.2%,p<0.0001), endomorph (30.3%,p<0.0001), mesomorph (17.8%,p<0.0001), back strength (8.9%,p<0.0001), right hand grip strength (5.8%,p<0.001), left hand grip strength (6.5%,p<0.001), less ectomorph (14.1%,p<0.001) and less time to finish 2000m (2.2%,p<0.0001) in open category rowers than light weight category. The 2000m rowing time was significantly (p<0.001) correlated with age (r=-0.459), height (r=-0.340), weight (r=-0.506), back strength (r=-0.458), right hand grip strength (r=-0.311) and left hand grip strength (r=-0.333). Body fat percentage (r = 0.191) and mesomorphic somatotype (r=-0.223) were correlated significantly (p<0.05) with performance. Multiple regression analysis identifies age, height, weight and body fat percentage as strong predictors of 2000m rowing ergometer performance (R=0.730). Combining strength components with the above is also a good predictor of 2000m rowing time (R=0.704). 2000m time(s)=519.211-0.480x age+0.111x height-1.836x weight+1.503x body fat%+0.010x back strength-0.099x right hand grip strength-0.075x left hand grip strength. In this context, these decisive physical and strength variables can be used to predict performance, improving training capability and identifying talents.

Research of the results of the Ukrainian Championship in rowing on ergometers as a stage of selection for the national team.

“…Показники відсотку жиру в організмі (r = 0,191) та характеристики мезоморфного соматотипу (r = -0,223) корелювали з результатом веслування на ергометрі на дистанції 2000 м (p<0,05). Множин ний регресійний аналіз дозволив визначити вік, довжину та масу тіла, відсоток жиру в організмі як значні фактори для прогнозування ефективності веслуванні на ергометрах 2000 м (r = 0.730) [8].…”

Equation for analyzing the peak power in aquatic environment: An alternative for olympic rowing athletes

“…Thus, performing simulations of the official competitions of the sport can be of great value for the evaluation and advancement of the athletes' performance [2,6]. In addition, given the importance of force capacities, anthropometric variables (i.e., weight, height, length of legs and body span) and muscular strength of the trunk and upper and lower limbs are also associated with the performance of rowers [2,[6][7][8]. To further support this relationship, Durkalec-Michalski et al, [9] stated that muscle power and body mass are determinants for the specific performance of rowers during official tests and competitions.…”

“…cannot be modulated by sports training [2,[5][6][7][8][9]. However, these variables influence the "biomechanical levers" of the human body during the production of muscle strength [2,[5][6][7][8][9]. This fact can be interesting during the selection process of young sports talents in relation to the specificity of force production in rowing [2,[5][6][7][8][9].…”

Uso de suplementos nutricionales deportivos en remeros de elite: diferencias entre nacionales e internacionales (Use of sports nutritional supplements in elite rowers: difference between national and international)

“…Estas demandas funcionales y fisiológicas dependen principalmente de las características antropométricas del atleta, factor crucial en deportes de élite (Battista, Pivarnik, Dummer, Sauer, & Malina, 2007;Rakovac et al, 2011), como ocurre en el remo de alta competición (Bechard et al, 2009). El remo es un deporte de potencia y resistencia (Jensen, 2011;Jürimäe et al, 2010;Majumdar, Das, & Mandal, 2017;Rakovac et al, 2011) consistente en superar una distancia de 2000 m oficiales (Boegman & Dziedzic, 2016;Majumdar et al, 2017), en un intervalo de tiempo que varía entre los 320 y 460 segundos (Bourgois, Steyaert, & Boone, 2014;Majumdar et al, 2017). La competición se desarrolla en diferentes modalidades deportivas, en función del género y el peso del atleta, además del tipo de embarcación competitiva (Boegman & Dziedzic, 2016;G.…”
