ABSTRACT 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: Various exercise interventions have been shown to benefit weight control and general health in different populations. However, very few studies have been conducted on martial arts exercise (MAE). The objective of this pilot study is to evaluate the efficacy of 12 weeks of MAE intervention on body composition, serum biomarkers and quality of life (QOL) in overweight/obese premenopausal women. We found that subjects in the MAE group did not lose body weight, while they significantly decreased fat-free mass and muscle mass as compared to those in the control group, who demonstrated an increase in these parameters. The MAE group demonstrated an increase in serum IGF-I concentration, but no change in others. MAE may be a feasible and effective approach to improve body composition and QOL in overweight/obese premenopausal women. Our study underscores the need for further studies using larger samples to establish possible benefits of MAE in various populations.

    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.

    ABSTRACT: Our aim was to determine the effects of resistance training on cardiovascular risk factors in postmenopausal women. Forty-five women were included in the study. Resistance exercises were done with an intensity of 60% of 1-Repetition Maximum, for 12 weeks. Heart rate, blood pressure, estimated peak VO(2), lipid profiles, and homocysteine levels were evaluated. There were significant time and group interactions for body mass index (p = .02), heart rate (p = .04), systolic blood pressure (p = .03), estimated mean peak VO(2) (p = .00), and total cholesterol (p = .00), but there were no interactions with other evaluated parameters. Resistance training has beneficial effects on particular cardiovascular risk factors in postmenopausal women.
