Effects Of Brisk Walking Research Articles

Acute effects of brisk walking on sugary snack cravings in overweight people, affect and responses to a manipulated stress situation and to a sugary snack cue: a crossover study.

Research has shown that acute exercise reduces urges for chocolate in normal weight people. This study aimed to examine the effects of an acute exercise bout on urges to consume sugary snacks, affect as well as ‘psychological and physiological responses’ to stress and a ‘sugary snack cue’, in overweight individuals. Following 3 days of chocolate-abstinence, 47 overweight, sugary snack consumers were assessed, in 2 randomly ordered conditions, in a within-subject design: 15-min brisk walk or passive control. Following each, participants completed 2 tasks: Stroop color–word interference task, and handling sugary snacks. Urges for sugary snacks, affective activation and valence were assessed. ANOVAs revealed significant condition x time interaction effects for: urges to consume sugary snacks, affective valence and activation. Obtained data show that exercise reduces urges for sugary snacks and attenuates urges in response to the stress situation and the cue in overweight people.

Effect of Brisk Walking in 1 or 2 Daily Bouts and Moderate Resistance Training on Lower-Extremity Muscle Strength, Balance, and Walking Performance in Women Who Recently Went Through Menopause: A Randomized, Controlled Trial

Menopause may induce a phase of rapid decreases in bone mineral density, aerobic fitness, muscle strength, and balance, especially in sedentary women. The purpose of this study was to examine the effects and feasibility of an exercise program of 1 or 2 bouts of walking and resistance training on lower-extremity muscle strength (the force-generating capacity of muscle), balance, and walking performance in women who recently went through menopause. The subjects were 134 women who recently went through menopause. The study was a 15-week, randomized, controlled trial with continuous and fractionated exercise groups. The outcomes assessed were lower-extremity muscle strength, balance, and walking time over 2 km. Feasibility was assessed by questionnaires, interviews, and training logs. One hundred twenty-eight women completed the study. Adherence to the study protocol was 92%. Both continuous and fractionated exercise groups improved equally in lower-extremity muscle strength and walking time but not in balance. Almost 70% of the subjects considered the program to be feasible. Two daily walking sessions caused fewer lower-extremity problems than did continuous walking. Brisk walking combined with moderate resistance training is feasible and effective. Fractionating the walking into 2 daily sessions is more feasible than continuous walking.

An 8-week randomized controlled trial on the effects of brisk walking, and brisk walking with abdominal electrical muscle stimulation on anthropometric, body composition, and self-perception measures in sedentary adult women

Objectives The aim of this randomized controlled trial was to examine the effects of an 8-week program of regular brisk walking, regular brisk walking with abdominal electrical muscle stimulation (EMS), and no exercise on hierarchical self-perceptions, and consider the mediating role of changes in anthropometric measures and body composition. Methods Thirty-seven sedentary healthy women (mean age=38.1; SD=9.3) provided written informed consent and participated in baseline testing on a range of anthropometric, body composition, and hierarchical self-perception measures. Subsequently participants were randomly assigned to an 8-week program of walking ( n = 13 ), walking+EMS ( n = 14 ), or a control ( n = 10 ) condition. At 8 weeks anthropometric, body composition and self-perception measures were re-assessed. Results In comparison with the control group, both walking groups had significant reductions in a number of anthropometric measures and improvements in self-perception measures. The improvements on both anthropometric measures and self-perceptions were greater for the walking+EMS condition, which indicated that changes in self-perception might be mediated by body changes. However, an assessment of the mediation effect between changes in anthropometric measures and self-perception changes did not support this finding. Conclusions An 8-week exercise program results in significant improvements in anthropometric measures and self-perceptions compared with no exercise. Changes in anthropometric measures appear to have limited influence on exercise-induced changes in self-perception and it is suggested that a subjective feeling that one's body is improving may be sufficient to enhance self-perceptions.

The Effects of Brisk Walking on Markers of Bone and Calcium Metabolism in Postmenopausal Women

The Effects of Brisk Walking on Markers of Bone and Calcium Metabolism in Postmenopausal Women

The effects of brisk walking on markers of bone and calcium metabolism in postmenopausal women.

Weight-bearing exercise has been shown to maintain or increase bone mass in younger as well as older individuals but the mechanisms by which mechanical loading affects bone metabolism are not known in detail. Twelve postmenopausal women participated in a single bout of brisk walking (50% of VO2 max) for 90 minutes. Calciotropic hormones and markers of type I collagen formation (PICP) and degradation (ICTP) were measured before the exercise, and 1, 24, and 72 hours following the exercise. Total body bone mineral content (BMC) and density (BMD) were measured by dual energy X-ray absorptiometry (DXA). Brisk walking did not induce any significant changes in the concentrations of ionized calcium, parathyroid hormone (PTH), calcitonin, or osteocalcin. A significant increase of PICP was noted 24 and 72 hours (P < 0.01) after exertion and a significant decrease in the concentration of serum ICTP at 1 hour (P < 0.05) was followed by an increase at 72 hours (P < 0.001). There was no significant difference between the increases in the concentrations of PICP and ICTP at 72 hours. Strong inverse correlations between the basal levels of PTH and BMD (r = -0.78; P < 0.01) as well as between osteocalcin and BMD (r = -0.83; P < 0.01) were noticed. The changes in serum levels of bone collagen markers indicate an altered bone collagen turnover due to this moderate endurance exercise. The results also support the fact that serum levels of PTH as well as those of osteocalcin are associated with total body BMD in postmenopausal women.
