**Sitting light (cm)** & 88.83 & 3.89 & 83.10-10.0 & 0.00 & 3.61 & 8.84-0.99 & 91.01 & 2.01 & 8.80 & 8.03-0. Body height did not differ significantly between the groups. However, seniors (+10.50 kg, \(p\) = 0.001) and older juniors (+5.25 kg, \(p\) = 0.019) had significantly higher body mass than female juniors. Additionally, senior females had significantly higher values of body fat percentage (+6.34%, \(p\) = 0.026), BMI (+2.31 kg/m\({}^{2}\), \(p\) = 0.014), arm span (+7.97 cm, \(p\) = 0.028), and thigh skin fold (+7.13 mm, \(p\) = 0.018) than junior female rowers. As for anthropometric characteristics, the groups did not differ significantly in terms of SMM, lower limb length, body fat percentage (Parizkova formula), and measurements of skin folds on the biceps, triceps, scapula, suprailiac, abdomen, and lower leg. In motor performance tests, the senior female rowers covered the distance of 2000 m in the best time (7.45 min), which was significantly shorter than that of the older juniors (-0.45 min, \(p\) < 0.032) and juniors (-0.80 min., \(p\) < 0.001). Additionally, the older juniors had a significantly shorter time than the juniors (-0.40 min, \(p\) < 0.001). Female seniors and older juniors achieved significantly higher values of VO2 max in both relative (+11.01 mL/kg/min, \(p\) = 0.005 and +5.86 mL/kg/min, \(p\) = 0.034, respectively) and absolute (+1.34 L/min, \(p\) < 0.001 and +0.66, \(p\) = 0.002, respectively). The senior rowers developed the greatest power (254.80 W), which was significantly higher than that of the juniors (+72.66 W, \(p\) < 0.001) and older juniors (+41.83W, \(p\) = 0.004), and the older juniors generated significantly more power than the juniors (+30.83 W, \(p\) = 0.001). The senior females achieved significantly higher relative power and force max than the juniors (+0.56 W/kg, \(p\) = 0.002; and +207.13 N, \(p\) = 0.009).
