Abstract/OtherAbstract:
ABSTRACT: Over the past 30 years, endurance volumes have increased by more than 20% among the rowing elite, therefore informed decisions about the value of weight training over other possible activities in periodized training plans for rowing, need to be made. The purpose of this study was to quantify the changes in lower body strength development following two 14-week phases of intensive resisted on-water rowing, either incorporating weight training or rowing alone. Ten elite females performed two resisted rowing ('towing ropes' e.g. 8 x 3 mins) plus six endurance (e.g. 16 - 28 km at 70-80% maximum heart rate) and two rate regulated races (e.g. 8000 m at 24 spm) on-water each week. After a four week washout phase, the 14-week phase was repeated with the addition of two weight training sessions (e.g. 3-4 sets x 6-15 reps). Percent (±SD) and standardized differences in effects (ES ± 90% Confidence Interval) for five repetition leg pressing and isometric pulling strength were calculated from data ratio scaled for body mass, log transformed and adjusted for pre-test scores. Resisted rowing alone did not increase leg pressing (-1.0% ± 5.3%, P = 0.51) or isometric pulling (+5.3% ± 13.4%, P = 0.28) strength. In contrast, after weight training, a moderately greater increases in leg pressing strength was observed (ES = 0.72; ±0.49, P = 0.03), although differences in isometric pulling strength were unclear (ES = 0.56; ±1.69, P = 0.52). In conclusion, intensive on-water training including resisted rowing maintained but did not increase lower body strength. Elite rowers or coaches might consider the incorporation of high intensity non-fatiguing weight training concurrent to endurance exercise if increases in lower body strength without changes in body mass are desired.
