Η επίδραση του ρυθμού και της αγωνιστικής τακτικής στα φυσιολογικά και κινητικά χαρακτηριστικά κατά την κωπηλατοεργομέτρηση 2Km
Translated title:
The effect of stroke rate and pacing on kinetic and physiological variables during 2 km rowing ergometer
Summary:
The aim of the study was to investigate the relationship of stroke rate and pacing in physiological and kinetic parameters during 2 km rowing ergometer. In the first part of the study, 36 male (15.09±0.7 yrs) and 12 female (14.9±0.5 yrs) rowers participated in the study. Both sexes were asked to row 2 km on the Concept 2 Model D rowing ergometer at the best possible time. For the statistical analysis Anova repeated measures were used and Pearson’s product. The results showed that male rowers decreased the SL in higher stroke rate(r= -0.6, p=0.001). Strong relationship for both genders was found between SL and height and upper and lower extremities. Kinetic variables changed every 500m. Both sexes, rowed the 2km using the parabolic-shaped pacing strategy. In the second part, 15 male rowers aged 15.37± 1.34 yrs, height 175.96±6.34 cm, body mass 72.84±10.13 kg completed 3 different pacing strategies in Concept II rowing ergometer. The purpose of the study was to investigate the influence of different pacing strategies on performance and selected metabolic and kinetic parameters. Participants first performed in Concept 2 an incremental test to determine VO2peak (59.97±4.86 ml•kg-1•min-1). After a week, performed a baseline 2km ergometer rowing trial. From the baseline data (BPS), pacing strategies were developed for the first 1000m. A slow pacing strategy (SPS) 4% slower from mean velocity of BSP and an even pacing strategy (EPS) were developed. The results showed best performance time in BPS. Kinetic characteristics were found to be consisted over BPS, SPS and EPS with the exception of stroke length which was greater in SPS. No differences were found in La (mmol.l-1) in recovery between pacing strategies (p=0.308) No significant differences were found in metabolic parameters.
In conclusion, stroke rate has a strong relationship with stroke length (SL) and the kinetic characteristics of male and female rowers change every 500m of the race. In addition, male and female performance is different. BPS allowed rowers to cover the 2 km distance in higher stroke rate and in shorter performance time compared to SPS and EPS pacing strategies presenting same physiological responses.
