Effect of BMI on Knee Joint Torques in Ergometer Rowing
Karen Roemer, Tibor Hortobagyi, Chris Richter, Yolanda Munoz-Maldonado, and Stephanie Hamilton
Although an authoritative panel recommended the use of ergometer rowing as a non-weight-bearing form of exercise for obese adults, the biomechanical characterization of ergometer rowing is strikingly absent. We examined the interaction between body mass index (BMI) relative to the lower extremity biomechanics during rowing in 10 normal weight (BMI 18–25), 10 overweight (BMI 25–30 kg·m−2), and 10 obese (BMI > 30 kg·m−2) participants. The results showed that BMI affects joint kinematics and primarily knee joint kinetics. The data revealed that high BMI leads to unfavorable knee joint torques, implying increased loads of the medial compartment in the knee joint that could be avoided by allowing more variable foot positioning on future designs of rowing ergometers.
Effect of Beta-Alanine With and Without Sodium Bicarbonate on 2,000-m Rowing Performance
Ruth M. Hobson, Roger C. Harris, Dan Martin, Perry Smith, Ben Macklin, Bruno Gualano, and Craig Sale
Purpose:
To examine the effect of beta-alanine only and beta-alanine with sodium bicarbonate supplementation on 2,000-m rowing performance.
Methods:
Twenty well-trained rowers (age 23 ± 4 y; height 1.85 ± 0.08 m; body mass 82.5 ± 8.9 kg) were assigned to either a placebo or beta-alanine (6.4 g·d−1 for 4 weeks) group. A 2,000-m rowing time trial (TT) was performed before supplementation (Baseline) and after 28 and 30 days of supplementation. The post supplementation trials involved supplementation with either maltodextrin or sodium bicarbonate in a double-blind, crossover design, creating four study conditions (placebo with maltodextrin; placebo with sodium bicarbonate; beta-alanine with maltodextrin; beta-alanine with sodium bicarbonate). Blood lactate, pH, bicarbonate, and base excess were measured pre-TT, immediately post-TT and at TT+5 min. Performance data were analyzed using magnitude based inferences.
Results:
Beta-alanine supplementation was very likely to be beneficial to 2,000-m rowing performance (6.4 ± 8.1 s effect compared with placebo), with the effect of sodium bicarbonate having a likely benefit (3.2 ± 8.8 s). There was a small (1.1 ± 5.6 s) but possibly beneficial additional effect when combining chronic beta-alanine supplementation with acute sodium bicarbonate supplementation compared with chronic beta-alanine supplementation alone. Sodium bicarbonate ingestion led to increases in plasma pH, base excess, bicarbonate, and lactate concentrations.
Conclusions:
Both chronic beta-alanine and acute sodium bicarbonate supplementation alone had positive effects on 2,000-m rowing performance. The addition of acute sodium bicarbonate to chronic beta-alanine supplementation may further enhance rowing performance.
Individual and Crew Level Determinants of Collective Efficacy in Rowing
T. Michelle Magyar, Deborah L. Feltz, and Ian P. Simpson
The purpose of this study was to examine individual (i.e., task self-efficacy, rowing experience, and goal orientations) and group/boat level (perceptions of motivational climate and boat size) determinants of collective efficacy in the sport of rowing. Participants were 154 male and female rowers ages 13 to 18 years (M = 16.19, SD = 1.29). Approximately 24 hours prior to the regional championship regatta, participants completed a demographic measure, the Task and Ego Orientation in Sport Questionnaire, the Perceived Motivational Climate in Sport Questionnaire-2, and sport-specific individual and collective efficacy measures developed for the current study. Multilevel modeling revealed that task self-efficacy significantly predicted individual perceptions of collective efficacy, while perceptions of a mastery climate significantly predicted average collective efficacy scores at the group level.
Rowing Performance, Body Composition, and Bone Mineral Density Outcomes in College-Level Rowers after a Season of Concurrent Training
Kaelin C. Young, Kristina L. Kendall, Kaitlyn M. Patterson, Priyanka D. Pandya, Ciaran M. Fairman, and Samuel W. Smith
Purpose:
To assess changes in body composition, lumbar-spine bone mineral density (BMD), and rowing performance in collegelevel rowers over a competition season.
Methods:
Eleven Division I college rowers (mean ± SD 21.4 ± 3.7 y) completed 6 testing sessions throughout the course of their competition season. Testing included measurements of fat mass, bone-free lean mass (BFLM), body fat (%BF), lumbar-spine BMD, and 2000-m time-trial performance. After preseason testing, rowers participated in a periodized training program, with the addition of resistance training to the traditional aerobic-training program.
Results:
Significant (P < .05) improvements in %BF, total mass, and BFLM were observed at midseason and postseason compared with preseason. Neither lumbar-spine BMD nor BMC significantly changed over the competitive season (P > .05). Finally, rowing performance (as measured by 2000-m time and average watts achieved) significantly improved at midseason and postseason compared with preseason.
Conclusion:
Our results highlight the efficacy of a seasonal concurrent training program serving to improve body composition and rowing performance, as measured by 2000-m times and average watts, among college-level rowers. Our findings offer practical applications for coaches and athletes looking to design a concurrent strength and aerobic training program to improve rowing performance across a season.
Rowing in Los Angeles: Performance Considerations for the Change to 1500 m at the 2028 Olympic Games

At their Ordinary Congress in November 2021, World Rowing announced that they had accepted the proposal to host the 2028 Los Angeles (LA) Olympic Rowing regatta at the Long Beach Marine Stadium, a venue that is restricted to a maximum racing length of 1500 m. 1 Pending formal approval, a possible
The 1,500-m Rowing Performance is Highly Dependent on Modified Wingate Anaerobic Test Performance in National-Level Adolescent Rowers

Purpose:
The aim of the current study was to determine whether the anaerobic performance assessed by a modified Wingate test could account for the 1,500-m rowing ergometer performance in young competitive rowers.
Methods:
Fourteen national-level adolescent rowers performed on a rowing ergometer i) a 30-s allout exercise (i.e., modified Wingate test) and ii) a 1,500-m all-out exercise (i.e., rowing performance). For each of these two exercises, the mean power output was considered as the main performance criterion (PWIN and P1500, respectively).
Results:
PWIN was correlated to P1500 (r 2 = .83, p < .0001, β = 100%). Furthermore, the estimated total muscle mass was correlated to PWIN and P1500 (r 2 = .72 and r 2 = .83, p < .0001, β = 100%, respectively). The allometric scaling also indicated that total muscle mass accounts 62% for the relationship between PWIN and P1500.
Conclusion:
Our results highlight the importance of considering the contribution of total muscle mass and anaerobic energy pathways to 1,500-m rowing performance in competitive adolescent rowers. Therefore, the modified Wingate test could be used by rowing coaches to potentially identify talented young rowers.

Lightweight double sculls (LM2x) will be the only lightweight rowing discipline to be retained in the Paris 2024 Olympic Games. With rowing times in LM2x typically ranging between 6 minutes 15 seconds and 6 minutes 40 seconds, rowers require both a high aerobic and anaerobic performance level. 1
