NCAA and IRA performance times of men and women improved across competition year [* denotes a significant effect of time, p < 0.001]; however, women improved more than men [† denotes a significant time × sex interaction, P = 0.001] for the heavyweight (A) and lightweight class (B). Note that heavyweight women compete in the NCAA and lightweight men and women and heavyweight men in the IRA.
Fig 2.
NCAA and IRA relative performance (% 1st place) across finishing place for heavyweight (A) and lightweight class (B). The reduction in relative performance was greater for men than women [# denotes greater reduction in men, place × sex, P < 0.001] for the heavyweight class (A). Conversely, the reduction in relative performance was greater for women compared with men [† denotes greater reduction in women, place × sex, P < 0.001] for the lightweight class (B). Note that heavyweight women compete in the NCAA and lightweight men and women and heavyweight men in the IRA.
Fig 3.
Ergometer performance times (“erg times”) of men and women in the Junior World Indoor Rowing Championships improved across competition year [* denotes significant time effect, P < 0.001]; although, women improved more than men [† denotes a significant time × sex interaction, P = 0.001] for the heavyweight (A) and lightweight class (B) during the World Indoor Championships.
Fig 4.
In the Junior World Indoor Rowing Championships, relative ergometer performance (% 1st place) reduced across finishing place (place effect, P < 0.001); further, women had greater reductions compared to men [† denotes a significant place × sex interaction, P = 0.001] for heavyweight (A) and lightweight class (B).
Fig 5.
Sex difference in performance increased across finishing place for Junior World Indoor Championships [* denotes significant place effect, P < 0.001]; although, the sex difference was less for the heavyweight (open triangle) compared with the lightweight rowers (filled triangle) [† denotes a significant place × weight class interaction, P = 0.001] for top 16 place finishers.
Fig 6.
Participation of men (filled circles) and women (open circles) competing in the NCAA regardless of weight class (A), in the heavyweight division of Junior Championships (B), and in the lightweight division of the Junior Championships (C). A: Participation among the heavyweight women in the NCAA increased linearly (y = 113.1x + b, r2 = 0.847, P < 0.001); however, there was no significant regression among men in the NCAA. B: Participation increased among heavyweight men and women competing in the Junior Championships (y = 10.3x + b, r2 = 0.908, P < 0.001; y = 11.7x + b, r2 = 0.889, P < 0.001, respectively). C: Participation increased among lightweight men and women competing in the Junior Championships (y = 9.9x + b, r2 = 0.861, P < 0.001; y = 7.4x + b, r2 = 0.714, P < 0.001, respectively). (y = total number of participants, x = year of competition, b = constant).
