BACKGROUND: This study investigated the influence of resistance exercise training on components and markers of metabolic syndrome in pre and postmenopausal women.
METHODS: Forty-three women were randomly divided in trained premenopausal (PRE-MR, N.=9, 44.0±5 years), trained postmenopausal (POS-MR, N.=11, 54.7±8 years), control premenopausal (PRE-MC, N.=11, 39.5±4 years) and control postmenopausal (POS-MC, N.=12, 54.9±6 years). The training was conducted for 12 weeks, 3-5 sessions per week with progressive loads (10 to 12 repetitions; 50% to 80% of 10RM). Blood pressure, glucose, lipid profile and waist circumference, gamma glutamyl transferase and malonildehyde was measured at pre and post training.
RESULTS: Despite the strength gains seen in trained women, did not change in any of the variables. Values between pre- and post-training periods in PRE-MR and POS-MR respectively were 85.4±8 mg/dL vs. 86.0±5 mg/dL and 99.7±24 mg/dL vs. 91.2±20 mg/dL to glucose; 192.0±43 mg/dL vs. 186.5±44 mg/dL and 212.7±34 mg/dL vs. 208.9±37 mg/dL to total lipoproteins; 94.7±9 cm vs. 92.6±7 cm and 97.1±12 cm vs. 94.2±12 cm to waist circumference. Blood pressure showed descritively reduction (116.0±14 mmHg vs. 118.0±10 mmHg and 127.8±12 mmHg vs. 119.8±11 mmHg to pre- and postmenopausal respectively). Effect size to postmenopausal was 0.69. Results for markers was 15.8±4 U/L vs. 14.3±3 U/L and 15.9±6 U/L vs.14.8±5 U/L to gamma glutamyl transferase and 3.7±1μM vs. 4.2±1 μM and 2.8±1 μM vs. 2.5±1 μM to malonildehyde.
CONCLUSIONS: Twelve weeks of resistance training do not affect blood pressure, glycaemia, body composition or metabolic syndrome markers and lipidic peroxidation in pre and postmenopausal women. However increasing sample size can result in statistical reduction to blood pressure only in postmenopausal woman.
