Background: Stationary (SE) and dynamic (DE) rowing ergometers, that are utilized for indoor training and physical assessment of competitive rowers, may elicit different physiological and biomechanical responses. The present study used SE and DE ergometers to examine submaximal and peak physiological and biomechanical responses during an incremental rowing test. Methods: Twelve National Collegiate Athletic Association (NCAA) Division I oarswomen performed seven-stage rowing tests with the last stage performed with maximal effort. Heart rate (HR), lactate (LA), oxygen uptake (VO2), ventilation (VE), stroke rate (SR), gross efficiency (GE), and rating of perceived exertion (RPE) were obtained; while trunk, hip, knee, shoulder, and elbow ranges of motion (ROM) were measured. Results: SR was higher at maximal stage DE (29.3 vs. 34.8 strokes/min, p = 0.018, d = 1.213). No difference occurred in responses of maximal stage HR, RPE, VO2, VE, LA, or GE between the two ergometers. Submaximal LA and SR were greater on the DE for all submaximal stages. Submaximal VE was greater on the DE for all submaximal stages except Stage 3 (p = 0.160, d = 0.655). VO2 was higher on the DE Stages 2–5. GE was higher on the SE for Stages 2–5. Athletes showed increased trunk (p = 0.025, η p 2 = 0.488) and knee (p = 0.004, η p 2 = 0.668) ROM on SE. Conclusion: Rowing on the DE appears to elicit a greater stroke rate and more optimal joint angles especially at high intensities. Hence, the DE is worthy of consideration as a preferred ergometer for women rowers. [ABSTRACT FROM AUTHOR]

Modern diagnostics in rowing enables more and more possibilities for recording, and comparing numerous stroke variables. At the same time, many coaches fall into the trap of strict respect for the prescribed norms, ratios, and temporarily results, which the athlete must achieve if he wants to stay in the world of competitive rowing. On the example of the comparison of rowing schools RC "Danubius" and RC "Partizan", descriptive indicators are on the side of RC "Danubius" at a time of 2000m, average force and average power. No significant differences were found in average force (sig = 0,167) between rowers of RC "Danubius" and RC "Partizan", while statistically significant differences were recorded in time at 2000m (sig = 0,036) and power (sig = 0,02) in favor of rowers of RC “Danubius”. On the other hand, a higher correlation of average force (-0,955) and power (-0,928) with time on 2000m was achieved by RC "Partizan" than RC "Danubius" (-0,931) and (-0,896). The correlation between the average force, and the average power within one team shows a higher correlation for RC “Partizan" (0,95) compared to RC "Danubius" (0,755). The obtained results are not enough for single rower or crew elimination from competition to recreational section in the process of too frequent and strict selection of rowers, considering different possible ways of building rowing techniques and numerous parasitic factors that may affect measured variables, specialy at the age under 14 and novice rowers in general.

Aim of this study was to investigate changes in blood sugar level after aerobic workout on rowing ergometer. Tested group consisted of Slovak rowers (n: 6, average age: 22.2±4.9 years, average height: 183.5±4.0 cm, average weight: 79.5±6.0 kg). Group undertook 4 tests: lactate curve, glycaemic profile, rowing exercise at intensity of anaerobic threshold (IANT) and rowing exercise at intensity of aerobic threshold (IAT). Blood sugar level was measured during 120 min. intervals before workout and after workout with Accu-Chek Active unit. We used nonparametric Wilcoxon signed-rank test (p<0.05) for dependent files for evaluation of the results. Results have shown that the difference between average fluctuation of blood sugar during 120 minutes post- and pre-workout is not significant. Difference of glycaemia (by 2.2 mmol.l-1, 46% resp.) immediately before and after the IANT test was significant (p<0.05). Difference of glycaemia (by 0.4 mmol.l-1, 7% resp.) immediately before the IAT test and after the test was not significant. [ABSTRACT FROM AUTHOR]

This case study reports the results of a 12-year (2005-2016) follow-up study of two Olympic champion rowers. The rowers were prospective athletes at the junior level when the study began, and we monitored their relevant physiological and performance data annually. Our findings indicated that their VO2max gradually increased up to about 22 years of age and leveled off at a value of approximately 7 l·min-1 with minimal fluctuations thereafter. However, the variables that directly influence the VO2max changed. There was an age-related decline in maximal heart rate of about 0.5 beats·year-1, while oxygen pulse, which serves as an indirect measure of stroke volume, correspondingly increased by about 1 ml O2·beat-1 per year, allowing the athletes to maintain exceptional VO2max values. Maximal minute power of the studied rowers, derived each year from their ramp-wise tests, closely resembled the mean power output sustained during the 2000-m all-out tests on a rowing ergometer. A 12-year improvement of 28% and 33% occurred for the mean power output sustained over 2000 and 6000-m on a rowing ergometer, respectively. The findings contribute to the body of knowledge on athletes representing the true elites of their respective sports. [ABSTRACT FROM AUTHOR]

The goals of this article are to provide power-to-weight relationships, changes in which are predictive of changes in performance for athletics (running, jumping and throwing), for swimming and for rowing. Also this article will estimate improvements in the efficient application of power exhibited by Olympic champions in those same events over the span of the modern Games. For the former goal, the ergometer power output of an athlete, measured under laboratory conditions, is modeled in terms of training, lean body mass and a cranking term as reflected in upper arm and shoulder volume. The laws of physics are used to relate event performance to efficiency and to a power-to-weight relationship specific to each event, with both efficiency and power-to-weight raised to an exponent specific to each event. The power-to-weight relationship, in turn, depends on training and on a lean-to-total body mass relationship. The ratios of female/male Olympic championship performances are then used since significant differences may be observed. Further, the relative need for upper arm and shoulder strength may be estimated for throwing and rowing. Physiological values estimated from the ratio of female/male Olympic winning performances in athletics and swimming compare closely with actual physiological relationship, validating that analysis. Rowing relationships were also validated from performance-physiological considerations. Having validated the analysis, reliable relationships then follow between changes in the power-to-weight ratio and event performance. As to the latter goal, the observed mean improvement in winning performance per Olympiad is found for each event, leading to estimated efficiency improvement per Olympiad. [ABSTRACT FROM AUTHOR]

The aim of the study was to determine the effect of selected individual factors (independent variables) on the dependent variable of a simulated rowing distance in a group of physically inactive females. The independent variables were the women's age, body mass (kg) and height (cm), and the BMI index. The time required to cover the simulated distance of 1000 m was adopted as the dependent variable. The study involved 258 female students who participated only in the obligatory physical education classes. Research revealed that the relationships between anthropometric parameters and the time required to complete 1000 m on a rowing ergometer differ among physically inactive women and elite rowers. In both physically inactive women as well as elite rowers an increase in body height had a positive influence on the time (shorter time). In the case of body mass, its increase in our study subjects resulted in poorer times, which is contrary to the results of studies conducted on elite rowers. This is most likely due to the fact that the body mass of athletes consists mainly of lean body mass, whereas physically inactive females are characterized by a higher percentage of body fat. Moreover, the time taken to complete the rowing trial was shortest for students with BMI values ranging from 17 to 21. The conducted research led to the conclusion that the analyzed anthropometric parameters affect the time needed by women to cover a distance of 1000 m on a rowing ergometer. Further studies should be conducted to include additional anthropometric and physiological parameters. [ABSTRACT FROM AUTHOR]

The aims of this study were to establish whether anthropometry, muscle strength and endurance accounted for differences between junior and senior elite rowing ergometer performance, and to determine annual development rates for juniors associated with training. Twenty-six junior (8 females, age 18.0±0.3 years and 18 males, age 17.9±0.2 years) and 30 senior (12 females, 23.7±3.0 years and 18 males, 24.0±3.9 years) heavyweight rowers, were assessed anthropometrically, performed a 2000-m ergometer time-trial, and completed various muscular strength and endurance tests. There were no anthropometrical differences between males; however after controlling for body-fat and standing-height, senior females were of greater body-mass (70.5±4.6 kg and 77.2±5.9 kg, P = 0.01) and sitting-height (89.8±2.2 cm and 92.2±6.1 cm, P = 0.04) than juniors. Moderate to very large standardised differences in all strength and endurance tests were observed between juniors and seniors (effect size (ES) range 0.9–1.9). Greater development rates (5.0% to 6.0%) and adjusted 2000-m performance was associated with upper-body strength (males) and endurance (females). In conclusion, after identification of desirable anthropometry, the 2000-m ergometer potential of juniors may be accounted for by upper-body strength and endurance. [ABSTRACT FROM AUTHOR]

This study evaluated the impact of a high-intensity strength training session on rowing sprint performance. Ten male club rowers performed a baseline counter-movement jump (CMJ) and a 250 m rowing ergometer sprint (250 m). Twenty-four hours after baseline, participants performed a high-intensity strength training session (ST) consisting of multi-joint barbell exercises. At 24 h, 48 h and 72 h post-ST, CMJ and 250 m were repeated alongside assessment of plasma creatine kinase (CK) and perceived muscle soreness. At 24 h post-ST 250 m performance decreased significantly (90% CI: 0.3 - 0.7 s), but returned to pre-test values at 48 h. There was a significant decrease in CMJ height at 48 h post ST (90% CI: -0.7 - -4.1 cm). Perceived muscle soreness was significantly greater than baseline at all assessed time points following ST (p < 0.05). There was a significant increase in CK from baseline to 24 h (90% CI: 146 - 390 U/L). High-intensity strength training was observed to adversely affect 250 m rowing ergometer performance after 24 h and coincided with transient muscle damage. [ABSTRACT FROM AUTHOR]

This case study reports the results of a 6-year (2005-2010) follow-up study of a world-class rowing crew, the current world champions. The rowers were 15-16 years old and prospective competitors at the junior level when the study began in 2005, and we monitored their physical, physiological, and rowing ergometer performance data annually. Our findings indicated that over the 6-year period gains in stature, averaged across rowers, amounted to only +2 cm (+1%). In contrast, body mass increased by +9 kg (+10%) and fat-free mass by +11 kg (+15%). A significant linear trend (R (2) = 0.998, P < 0.001) and a +26% increase in maximal oxygen uptake (in L min(-1)) was evident from 2005 to 2009, resulting in a leveling-off and a crew average of ~6.6 L min(-1) (~70 mL kg(-1) min(-1)) during the last 2 years of assessment. Power output at anaerobic threshold increased by +23%, subsequently amounting to a crew average of 359 W in 2010. Oxygen uptake at anaerobic threshold, expressed as a percentage of maximal oxygen uptake, changed little and ranged between 82 and 85%. A curvilinear regression provided the best fit to describe the 6-year improvement (+7%) in 2000 m (R (2) = 0.984, P < 0.001) and 6000 m (R (2) = 0.989, P < 0.001) rowing ergometer performance times. Performance-related physical and physiological parameters seem to level-off at about 20 years of age, which may partly explain the corresponding stabilization in ergometer performance times over the last years of assessment.

We evaluated (1) the test-retest reliability of the Wingate test conducted on a rowing ergometer, and (2) the sensitivity of this test in determining the differences in performance attained by 12- to 18-year-old rowers. Altogether, 297 male rowers aged 12.0-18.9 years (mean ± s: 14.8 ± 1.7) completed a maximal 30-s test on a rowing ergometer, and 80 rowers representing all age groups were retested after 5-7 days. No change was evident in participants' performance in terms of mean power output (P = 0.726; Cohen's d = 0.04), maximal power output (P = 0.567; Cohen's d = 0.06), and minimum power output (P = 0.318; Cohen's d = 0.11) in the second test. The intra-class correlation coefficients were high (≥0.973) and coefficients of variation were low (≤7.3%). A series of analyses of variance were used to compare the performances among 12- to 18-year-old rowers, and age-related increases in performance were evident (P < 0.001; Cohen's d = 1.91-1.96). The age-related increases in performance were similar, although reduced, when the effects of body mass were partitioned out when using analysis of covariance (P < 0.001; Cohen's d = 0.82-0.85). The results suggest that: (1) the described test is reliable and can be used for maximal-intensity exercise assessment in youth rowing, and (2) it discriminates performance among 12- to-18-year-old rowers.

The purpose of the present study was to test the hypothesis that large increases in blood lactate concentration ([La]b) and/or body temperature may occur during an endurance training on a rowing ergometer and disrupt training. The influence of an increase in air convection on the capacity to perform a prolonged exercise was also explored. Ten trained oarsmen were asked to undergo twice, in control (C) and increased air ventilation (AV) conditions, two 30-min trainings on a rowing ergometer at a work rate corresponding to 2.5 mmol·L-1 of [La]b determined during a previous incremental exercise (P2.5). Four subjects did not complete the training session in C despite a steady state in [La]b in two of them. In these four subjects, the end of the exercise was associated with the highest measured rectal temperatures (Tre, 39.4 ± 0.1 °C) and rate of perceived exertion (RPE, 17.8 ± 0.3). Regarding the six other subjects, their heart rate, oxygen uptake, RPE, Tre and water loss values were lower (p <0.05) in AV than in C. [La]b displayed the same profile in C and AV. This study suggests that i) high body temperature may constitute a significant factor of perceived exertion and disrupt indoor training session, and ii) capacity to perform an endurance training on a rowing ergometer was improved by increasing air convection.

During 2000m indoor rowing performances, the estimated aerobic and anaerobic contribution are 65-75% and 25-35%, respectively2. In considering that anaerobic power could be an important predictor of performance1, the aim of this studywas to analyse the relationship between the power outputs during a Wingate anaerobic test (WAnT) on a cycling ergometer and a 2000m rowing ergometer performance in young rowers. In two separate days, 11 young (14.9±1.1yrs) male rowers performed a 2000mindoor rowing ergometer performance and a 30s WAnT on a cycling ergometer. WAnT peak power (PP) and mean power (MP), and 2000m time indoor rowing performance (t2000) were collected. Moreover, PP and MP were normalized with respect to body mass. Pearson correlation coefficients (r) were used to determine the association between t2000 and absolute and normalized PP and MP values. Absolute PP and MP were 888.1±133.2W and 548.5±74.4W, respectively. The relative picture for normalized values was 13.4±1.5 W·kg-1 and 8.2±0.6 W·kg-1. High associations emerged between t2000 (431.5±19.5s) and absolute PP (r=-0.900, P=<0.05) and MP (r=-0.800, P>0.05) values, whereas no significant relationship was observed for normalized PP (r=-0.585, P=0.058) and AP (r=-0.561, P=0.072) values. These findings indicate that PP and MP could be considered significant predictors of 2000m rowing ergometer performances, substantiating also the relevance of the anaerobic energy pathways to the 2,000m rowing performance.
