Work-time profile, blood lactate concentration and rating of perceived exertion in the 1998 Greco-Roman wrestling World Championship

Abstract

The aim of this study was to examine work-time profiles, blood lactate concentrations and perceived exertion among Greco-Roman wrestlers in the 1998 World Championship. Forty-two senior wrestlers from nine nations were studied in 94 matches. Each match was recorded with a video camera (Panasonic AG 455, film rate: 25 Hz) and analysed for duration of work (wrestling) and rest (interrupt) periods. Blood lactate concentration was determined with an electrochemical device (Analox P-LM5) and a rating of perceived exertion scale (Borg) was used to estimate general exertion and exertion in the extremity and trunk muscles. The mean duration of the matches was 427 s (range 324-535 s), with mean durations of work and rest of 317 and 110 s, respectively. The mean periods of work and rest were 37.2 and 13.8 s, respectively. Mean blood lactate concentration was 14.8 mmol x 1(-1) (range 6.9-20.6). The difference in mean blood lactate concentration between the first- and final-round matches was not significant (P > 0.05). Blood lactate concentration was significantly higher (P < 0.04) in matches of long duration than in those of short duration. The mean general rating of perceived exertion for all matches was 13.8 according to the scale used. Most of the wrestlers (53.3%) perceived exertion to be highest in the flexors of the forearm, followed by the deltoids (17.4%) and the biceps brachii muscles (12.0%). In addition to a relatively high rating of perceived exertion in the arm muscles, this indicates a high specific load on the flexor muscles of the forearm.

Demandas técnico-táticas e fisiológicas de combates da luta olímpica

“…Na luta greco-romana, Nilsson et al (2002) mostraram que, no Mundial Sênior Campeonato de 1998, a duração média de trabalho e descanso foi de 37,2 ± 9,8 s e 13,8 ± 6,0 s, respectivamente. A média de tempo total dos combates foi 427 s com um tempo total de esforço de 317 s e pausa de 110 s.…”

Comparison of Somatotype Characteristics and Anthropometric Proportional Relations of Elite Wrestlers Between Styles and Weights

“…Bompa had stated that the age for achieving high performance in wrestling sport is between 24 and 28 (Bompa & Haff, 2009). Average age of wrestlers who had taken place in the Greco-Roman Style World Wrestling Championship was detected to be 25.8 years (Nilsson, Csergö, Gullstrand, Tveit & Refsnes, 2002). By the study in which age depending samples of anthropometric characteristics of young wrestlers within the ages of 8 and 14 were examined, the subjects were separated into six groups according to their age ranges, and many anthropometric measurements were compared and at the end of the study only femur circumferences were found to be different (Camic et al, 2009).…”

Can Amateur Football Help Players Meet the Requirements for a Healthy Lifestyle? A Case Study

“…Based on Borg's RPE scale, Nilsson, Csergö, Gullstrand, Tveit, and Refnes [23] validated a modified version to estimate athletes' perceived exertion in specific body parts (muscles). At the end of each one of the training session, every participant was given an anatomical diagram showing anterior and posterior views of the body.…”
