Physical activity of Estonian family doctors and their counselling for a healthy lifestyle: a cross-sectional study.

Background: Physical activity offers major health benefits and counselling for it should be integrated into the medical consultation. Based on the literature, the personal health behaviour of the physician (including physical activity) is associated with his/her approach to counselling patients. Our hypothesis is that family doctors (FD) in Estonia are physically active and their recommendation to counsel patients with chronic diseases to use physical activity is high.

Lower limbs function and pain relationships after unilateral total knee arthroplasty.

The aim of the study was to evaluate gait characteristics, lower limbs joint function, and pain relationships associated with knee osteoarthritis of female patients before and 3 months after total knee arthroplasty at an outpatient clinic rehabilitation department. Gait parameters were registered, the active range of lower extremity joints was measured, and pain was evaluated. Gait characteristics, walking velocity, and knee joint's extension improved and pain diminished considerably 3 months after arthroplasty, nevertheless did not reach control group level.

Physical activity of depressed patients and their motivation to exercise: Nordic Walking in family practice.

The objectives of this study were to find out how motivated depressed patients are to exercise regularly, to measure the physical activity of depressed patients and to find out how regular Nordic Walking affects the mood and physical fitness of depressed patients. A cross-sectional study was carried out. Three years after the Prediction of Primary Episodes of Depression in Primary Medical Care study, telephone calls were made to 178 patients who had had depression during that study.

Evaluation of viscoelastic parameters of the skeletal muscles in junior triathletes.

Five male triathletes of the Estonian national junior team were observed during a seven-week competition period. The Myoton-2 equipment was used to describe the viscoelastic parameters of the skeletal muscles. The frequency of damped mechanical oscillation of the muscle tissue (Hz - indicating the tension in the muscle), logarithmic decrement of the oscillations (Theta - indicating the elasticity of the muscle) and stiffness (N m(-1)) of the muscle tissue were registered bilaterally in eight muscles in both the relaxed and the contracted states: BB - biceps brachii (caput longum); TB - triceps brachii (caput longum); BF - biceps femoris (caput longum); RF - rectus femoris; TA - tibialis anterior; GC - gastrocnemius (caput mediale); LD - latissimus dorsi; PM - pectoralis major (pars sternocostalis).

Growth hormone, cortisol and prolactin responses to physical exercise: higher prolactin response in depressed patients.

This study was designed to compare growth hormone, cortisol and prolactin responses to physical exercise in depressed patients and healthy comparison subjects. Patients fulfilled the DSM-IV diagnostic criteria for current major depressive disorder; subjective depressive symptoms were rated with Montgomery-Asberg Depression Rating Scale (MADRS) immediately before the experiment. Growth hormone, cortisol and prolactin were measured before and immediately after physiologically stressful bicycle cardiopulmonary exercise test.
