PURPOSE: The purpose of this study was to ssytematically investigate rowing related characterisctics of energy supplement of rowing in different distance, to provide biological basis for different training load.
METHODS: eleven elite athletes carried K4B2 portable metabolizing instrument and rowed 45s, 90s, 3.5min, 5min and 6.5min (the equivalent of 250m, 500m, 1000m and 1500m) strenuously with ergometer. Blood lactate gathered at resting and 1, 3, 5, and 7min after testing. According to Beneke’s method to calculate the situations of three energy supply systems.
RESULTS: The energy supply system ratio of rowing 2000m was 6.2% of ATP-CP ES (energy supply), 10.1% of anaerobic ES and 83.7% of aerobic ES. See the attached figure for more details.
CONCLUSIONS: Aerobic capacity was paramount for rowers, comparing with the literature, aerobic capacity has further improvement. Fifty percent cut-off point of aerobic and anaerobic in rowing emerged at about 690m. Rowing 45’s (simulating 250M) was the most suitable way to improve athletes’ ATP-CP ability. Rowing 90’s (simulating 500M) further stimulated the anaerobic ES. Rowing 3.5min (simulating 1000M) made the accumulation of blood lactate up to peak level, and the distance (1500m) was appropriate for improving athletes’ acid-resisting ability. The ratio of energy supply systems of rowing 5min (simulating 2000M) was close to competition distance and it can substitute 2000m’s training.
