This study in female and male rowers demonstrates that hemoglobin mass (Hb mass ), V̇o 2peak , and muscle strength increases with 8 wk of heavy strength training and that this response is not different between conventional (3 × 10 repetitions) and high-volume strength training (10 × 10 repetitions). Moreover, female rowers exhibited less hemoglobin per kilogram of lean body mass compared with their male counterparts, which likely contributes to sex differences in V̇o 2peak and rowing performance.
