Resistance exercise and lipoproteins in postmenopausal women.

The specific aims of this study were to quantify the effects of 12 weeks of resistance training, as well as a single session of resistance exercise on lipids and lipoproteins in obese, postmenopausal women. 21 obese, postmenopausal women, not on hormone replacement therapy (age=65.9 ± 0.5 yr; BMI=32.7 ± 0.8 kg/m(2)), were randomly assigned to control (n=12) and exercise (n=9) groups matched for age and BMI. For 12 weeks, 3 days/week, the exercise group performed 10 whole body resistance exercises (3 sets at 8-RM). Fasting (10 h) blood samples were collected immediately prior to and 24 h after the first and last exercise and control session. Serum was assayed for concentrations of total cholesterol, triglycerides, LDL-C, HDL-C, HDL 2-C, HDL 3-C, non-HDL-C and TC:HDL and LDL:HDL ratios. The exercise group exhibited a significant (P<0.01) improvement in muscular strength, but no change in BMI, body mass or body composition post-training. Total cholesterol, LDL-C and non-HDL-C were significantly (P<0.05) lower in the exercise compared to the control group following the 12 weeks of resistance training. Whole body resistance training provides obese, postmenopausal women a non-pharmacological approach for the reduction of lipid and lipoprotein-cholesterol concentrations.

Criminal responsibility and mental disorder in Britain and North America: a comparative study.

The relationship between criminal responsibility and mental disorder is traced and described in England, Scotland, Canada and the United States of America. In Britain the Mental Health Acts have now made argument over criminal responsibility and mental disorder largely obsolete, also bringing an increased medical influence to the dispositions, by the Courts, of mentally disordered offenders. In North America the question of the criminal responsibility of a mentally disordered accused remains an essential cornerstone in the equitable management of such individuals by the legal system. This article explores some of the problems encountered in the differing approaches.
