Aerobic workout on a rowing ergometer and blood sugar level

Abstract

Aim of this study was to investigate changes in blood sugar level after aerobic workout on rowing ergometer. Tested group consisted of Slovak rowers (n: 6, average age: 22.2±4.9 years, average height: 183.5±4.0 cm, average weight: 79.5±6.0 kg). Group undertook 4 tests: lactate curve, glycaemic profile, rowing exercise at intensity of anaerobic threshold (IANT) and rowing exercise at intensity of aerobic threshold (IAT). Blood sugar level was measured during 120 min. intervals before workout and after workout with Accu-Chek Active unit. We used nonparametric Wilcoxon signed-rank test (p<0.05) for dependent files for evaluation of the results. Results have shown that the difference between average fluctuation of blood sugar during 120 minutes post- and pre-workout is not significant. Difference of glycaemia (by 2.2 mmol.l-1, 46% resp.) immediately before and after the IANT test was significant (p<0.05). Difference of glycaemia (by 0.4 mmol.l-1, 7% resp.) immediately before the IAT test and after the test was not significant.
