Aerobic exercise is known to improve health-related quality of life (QoL). The aim of this study was to compare the effects of a 16-week walking program on eating behaviors and QoL between late premenopausal and early postmenopausal obese and sedentary women, once chronological aging is taken into account.
Sixteen women 49 +/- 2 years old and 14 women 53 +/- 2 years old, whose body mass index ranged between 29 and 35 kg/m, were subjected to three sessions per week of 45-minute walking at 60% of their heart rate reserve. Fat mass and lean mass (bioelectrical impedance), cardiorespiratory fitness estimated by maximum oxygen consumption (2-km walking test), eating behaviors (Three-Factor Eating Questionnaire), and QoL, estimated by the Short Form-36 Health Survey, Pittsburgh Sleep Quality Index, and Perceived Stress Scale-10 questionnaires, were recorded before and after exercise.
With the exception of a higher attitude of self-regulation in postmenopausal than in premenopausal women (P = 0.05), no between-group differences were observed in body composition, eating behaviors, and QoL at baseline. In all participants, body weight and fat mass decreased, whereas cardiorespiratory fitness increased after walking (0.001 < P < 0.0001). Situational susceptibility was the only eating behavior reduced after training in all women (P = 0.02). Neither the sleep quality index nor the perceived stress score changed in response to endurance exercise. Finally, in all women, Short Form-36 physical and mental scores increased after walking (0.001 < P < 0.05).
Despite modest body weight and fat mass losses, a 16-week walking program seems to be sufficient to improve physical and mental well-being, irrespective of menopause status.

ABSTRACT: To assess body weight composition in postmenopausal women and determine correlations with metabolic and hormonal parameters.
Medical records of 574 postmenopausal Caucasian Spanish women first time attending a menopause clinic were retrospectively reviewed. Retrieved information included general demographic data, type of menopause, time since menopause onset and baseline hormonal and metabolic parameters. A body mass index (BMI) value of >28.8 kg/m(2) was used to define obesity. The metabolic syndrome (METS) was diagnosed with three or more criteria: fasting glycemia ≥ 100 mg/dL, high density lipoprotein cholesterol (HDL-C) <50 mg/dL, triglycerides (TG) ≥ 150 mg/dL, blood pressure ≥ 130/85 mmHg and obesity (as defined above).
Mean age of the whole cohort was 49.9 ± 6.1 years, with 66% having a natural menopause. A 38.9% and 23.1% of all women were obese or had the METS, respectively. Obese women were older, had a higher parity, smoked less, had more time since menopause onset and a higher rate of surgical menopause as compared to non-obese ones (p = 0.001). BMI values positively correlated with age, time since menopause, parity, and glucose, TG and systolic blood pressure levels; displaying an inverse correlation with HDL-C and SHBG levels. SHBG levels inversely correlated with glucose, TG, HDL-C and systolic blood pressure levels.
In this Spanish postmenopausal population BMI significantly increased with age, time since menopause and parity displaying significant correlations with hormonal and metabolic parameters.

ABSTRACT: To estimate whether aerobic training has an effect on frequency of hot flushes or quality of life.
A randomized controlled trial.
Symptomatic, sedentary women (n = 176), 43-63 years, no current use of hormone therapy.
Unsupervised aerobic training for 50 minutes four times per week during 6 months.
Hot flushes as measured with Women's Health Questionnaire (WHQ) and Health-Related Quality of Life (HRQoL, SF-36), daily reported hot flushes on phone-based diary, cardiorespiratory fitness (CRF), and body composition.
Intervention group had larger decrease in the frequency of night-time hot flushes based on phone diary (P for month × group = 0.012), but not on WHQ scale. Intervention group had less depressed mood (P = 0.01) than control women according to change in WHQ score. Changes in WHQ score in depressed mood (P = 0.03) and menstrual symptoms (P = 0.01) in the intervention group were significantly dependent on frequency of training sessions. HRQoL was improved among the intervention group women in physical functioning (P = 0.049) and physical role limitation (P = 0.017). CRF improved (P = 0.008), and lean muscle mass increased (P = 0.046) significantly in the intervention group as compared to controls.
Aerobic training may decrease the frequency of hot flushes and improve quality of life among slightly overweight women.

ABSTRACT: Phototherapy improves cellular activation which is an important factor for the treatment of cellulite. The objective of this research was to develop and evaluate the effects of a new (noninvasive and nonpharmacological) clinical procedure to improve body aesthetics: infrared-LED (850 nm) plus treadmill training. Twenty women (25-55 years old) participated in this study. They were separated in two groups: the control group, which carried out only the treadmill training (n = 10), and the LED group, with phototherapy during the treadmill training (n = 10). The training was performed for 45 minutes twice a week over 3 months at intensities between 85% and 90% maximal heart rate (HR(max)). The irradiation parameters were 39 mW/cm(2) and a fluence of 106 J/cm(2). The treatment was evaluated by interpreting body composition parameters, photographs and thermography. This was primarily a treatment for cellulite with a reduction of saddlebag and thigh circumference. At the same time, the treadmill training prevented an increase of body fat, as well as the loss of lean mass. Moreover, thermal images of the temperature modification of the thighs are presented. These positive effects can result in a further improvement of body aesthetics using infrared-LED together with treadmill training.
