Physical activity, cardiorespiratory fitness, and metabolic outcomes in monozygotic twin pairs discordant for body mass index.

This study aims to investigate (i) how monozygotic (MZ) twin pairs who are discordant for body mass index (BMI) differ for objectively and subjectively measured physical activity (PA) and cardiorespiratory fitness (VO max) and (ii) associations of PA and VO max with adiposity and measures of metabolic health, in individual twins and independent of genetic and shared environmental effects within twin pairs. We examined 27 BMI-discordant and 14 BMI-concordant MZ twin pairs. Fat and fat-free mass (ffm) were measured by dual-energy X-ray absorptiometry and VO max by spiroergometry.

From the subarctic to the tropics: effects of 4-month deployment on soldiers' heat stress, heat strain, and physical performance.

The aim of the study was to evaluate the heat stress of Finnish male soldiers (N = 20, age 22.0 ± 2.5 years, body mass 78.

Orthopaedic manual therapy, McKenzie method or advice only for low back pain in working adults: a randomized controlled trial with one year follow-up.

Objective: To examine the effects of 2 manual therapy methods compared with one counselling session with a physiotherapist with "advice-only to stay active" for treating low back pain/leg pain and disability.

Design: A randomized, controlled trial with a 1-year follow-up.

Subjects: A total of 134 subjects with low back disorders.

Heritability of BMD of femoral neck and lumbar spine: a multivariate twin study of Finnish men.

Unlabelled: Of the 80% variation in BMD among male twins that is caused by genetics, part was explained by genetic influences on lifting strength and lean body mass/height. Lifting strength was significant in both the femoral and spine BMD and body weight only for lumbar BMD.

Introduction: The dominant role of heritability in BMD has been shown in twin studies among women.

Impairments, activity limitations and participation restrictions 6 and 12 months after breast cancer operation.

Objective: To describe the impairments of upper body and limbs, activity limitations and participation restrictions 6 and 12 months after operation for breast cancer and to examine the impact of impairments on activity limitations.

Design: A prospective survey 6 and 12 months after operation.

Patients: Ninety-six breast cancer patients.
