Background Inhibition processing is sensitive to aging, and an age-related decline in inhibition processing has been associated with an accelerated rate of progression to Alzheimer disease. Elderly women are two to three times more likely than age-matched men to have Alzheimer disease. Therefore, this study examined whether long-term high physical activity affects inhibitory processing, specifically among postmenopausal women. Methods In total, 251 candidates were screened using the Montreal Cognitive Assessment and the Raven’s Standard Progressive Matrices to assess their cognitive abilities and the International Physical Activity Questionnaire (Chinese version) to assess their physical activity levels. The participants were then grouped into either a long-term high physical activity group (defined as more than 3 days of high intensity activity per week and gross metabolic equivalent minutes (MET-minutes) higher than 1,500 MET-minutes/week or a gross MET higher than 3,000 MET-minutes/week obtained through walking or other moderate or high intensity activity) or a control group and matched for demographic and health characteristics as well as cognitive scores. Event-related potentials (ERPs) were recorded as participants performed a Go/No-go task to assess inhibition processing. Results The long-term high physical activity group (n = 30) had faster Go reaction times than the control group (n = 30), whereas no significant difference between the two groups was found in their performance accuracy on the No-go task. For the ERP results, the latency of N2 component was significantly shorter in the long-term high physical activity group than that in the control group. Discussion The results of this study suggested that long-term high physical activity may increase the efficiency of the inhibitory control system by increasing the activity of response monitoring processes.

Physical activity is a promising intervention to restore cognitive function after prolonged sedentary periods. However, little is known about the effect of short physical activity bouts on cognition especially among individuals that are used to physical activity. Therefore, the goal of the present study was to assess the impact of a single ten-minute physical activity bout on the cognitive domain of visual attention compared to sedentary behavior in a population of physically active sport students. Using a randomized controlled design, 51 healthy and physically active sport students [mean age: 22.3 (SD: 2.0) years, 33.3% female] were allocated to one of the following interventions in the break of a two-hour study course: physical activity group (running for ten minutes) and sedentary control group. Visual attention was measured post-intervention using a modified trail making test. Pre-, post-, and 30 min after intervention, perceived attention, and affective states were measured. Between-group comparisons were used to analyze whether visual attention and/or changes in perceived attention or affective states differed between groups. The physical activity group showed significantly higher visual attention post-intervention compared with the sedentary control group, p = 0.003, d = 0.89. Perceived attention, p = 0.006, d = 0.87, and arousal, p < 0.001, d = 1.68, showed a significantly larger pre- and post-intervention increase in the physical activity group compared with the sedentary control group, which was not evident 30 min after intervention. A single ten-minute running intervention in study breaks might help to restore the basal visual attentional domain of cognition after prolonged sedentary periods more effectively compared with common sedentary behavior in breaks between study lessons.

Abstract Aims To investigate the associations of physical-activity trajectories with the level of cognitive performance (CP) and its decline in adults 50 years of age or older. Methods We studied 38 729 individuals (63 ± 9 years; 57% women) enrolled in the Survey of Health, Ageing and Retirement in Europe (SHARE). Physical activity was self-reported and CP was assessed based on immediate recall, verbal fluency and delayed recall. Physical-activity trajectories were estimated using growth mixture modelling and linear mixed-effects models were used to investigate the associations between the trajectories and CP. Results The models identified two trajectories of physical activity: constantly high physical activity (N = 27 634: 71%) and decreasing physical activity (N = 11 095; 29%). Results showed that participants in the decreasing physical-activity group exhibited a lower level of CP compared to the high physical-activity group (immediate recall: ß = 0.94; 95% confidence interval [CI] = 0.92–0.95; verbal fluency: ß = 0.98; 95% CI = 0.97–0.98; delayed recall: ß = 0.95; 95% CI = 0.94–0.97). Moreover, compared with participants in the constantly high physical-activity group, participants in the decreasing physical-activity group showed a steeper decline in all cognitive measures (immediate recall: ß = −0.04; 95% CI = −0.05 to −0.04; verbal fluency: ß = −0.22; 95% CI = −0.24 to −0.21; delayed recall: ß = −0.04; 95% CI = −0.05 to −0.04). Conclusions Physical-activity trajectories are associated with the level and evolution of CP in adults over 50 years. Specifically, our findings suggest that a decline in physical activity over multiple years is associated with a lower level and a steeper decline in CP.

The associations of modifiable lifestyle-related factors with cardiovascular and all-cause mortality were examined in a population-based sample of older Taiwanese people. A total of 4176 individuals aged 50 years and older, with 11 years of follow-up, were analyzed. Current and former smokers had a higher risk of all-cause mortality compared with never smokers ([HR = 1.33; 95% CI = 1.12, 1.58], [HR = 1.39; 95% CI = 1.16, 1.68]). Low intake of vegetables and fruits was associated with a significantly higher risk of 1.43 (95% CI = 1.13, 1.81) for cardiovascular mortality and 1.22 (95% CI = 1.09, 1.38) for all-cause mortality. The low physical activity group at baseline who became part of the low, moderate, and high physical activity groups during follow-up had the following risks of cardiovascular mortality: ([HR = 2.89; 95% CI = 1.91, 4.36], [HR = 2.17; 95% CI = 1.29, 3.63], [HR = 1.59; 95% CI = 0.90, 2.82]). Similarly, the moderate physical activity group at baseline who became part of the low, moderate, and high physical activity groups during follow-up had the following risks of cardiovascular mortality: ([HR = 3.52; 95% CI = 2.14, 5.80], [HR = 2.25; 95% CI = 1.34, 3.80], [HR = 1.44; 95% CI = 0.78, 2.66]). The same tendencies were found in all-cause mortality. Smoking, diet, and physical activity were significantly modifiable lifestyle-related factors for mortality.Besides, individuals who decreased their physical activity had a significantly higher risk, whereas those who increased their physical activity had a significantly lower risk.

Abstract Objectives Although the effectiveness of high-intensity training has been widely recognized as positive in athletes, its application in a clinical context is not well established. There is enough evidence to confirm that high-intensity routines are safe and that at-risk populations, such as for overweight and obese subjects, can help from these weight loss treatments. The purpose of this study was to lead a trial to test whether manipulation of physical activity in extension to high protein diet intake would induce changes in total weight and body composition. Methods Sixty-eight healthy male volunteers were randomly assigned to one of the experimental groups: a control group with a low-level prescription of physical activity (1–4 METs), moderate physical activity group that performed 10.000 steps walking per day (5–8 METs) and intense physical activity group that trained exercises by at least 70% of VO2max three times a week (> 8 METs). All subjects followed a high-protein diet designed with a reduction of 500 kcal/day. Nutritional counseling was provided throughout the study period to help ensure dietary adherence. This intervention was delivered over twenty-four sessions as weekly one-on-one, face-to-face 30-min consultations. Results A significant reduction in body fat percentage was observed in the intense physical activity group (-20.9 ± 8.8 (CI95%: -25.6 – -16.2), p < 0.001). The change in muscle mass did not produce any significant differences between groups (p > 0.05). Concerning weight, a notable weight loss was found in those subjects who performed moderate or intense physical exercise, vs. those who did light exercise, (p < 0.001) and (p < 0.003), respectively. Conclusion our data strongly suggest that resistance training should be included, whenever possible, in any dietary treatment for improving the body composition of men with overweight or obesity.

The objective of this study was to compare the cardiac autonomic control of dyslipidaemia patients engaged in different levels of physical activity and to determine the predictive ability of physical activity for cardiac autonomic dysfunction in these patients. This study also aimed to compare the cardiac autonomic control of dyslipidaemia patients and healthy adults. 52 patients (age: 49.1±4.53 years) with dyslipidaemia were recruited along with 16 healthy adults. Physical activity levels were assessed by International Physical Activity Questionnaire, and subjects were divided into three categories – low, moderate, and high physical activity. Heart rate variability (HRV) analysis was performed for obtaining time and frequency domain parameters. Presence of cardiac autonomic dysfunction was defined as standard deviation of N-N intervals <44 ms. HRV parameters were compared between 3 groups of dyslipidaemia patients and healthy controls. Predictive ability of physical activity for cardiac autonomic dysfunction in dyslipidaemia was evaluated after adjusting clinical covariates. There was a significant difference between low-frequency power (cardiac sympathetic control), and ratio of low- and high-frequency (HF) power (sympatho-vagal balance) in low versus moderate physical activity group and low versus high physical activity group (P<0.001). Significant differences were also observed for HFnu power (cardiac vagal activity) and total power between the dyslipidaemia groups. Physical activity was found to be a significant (P=0.03), independent predictor of cardiac autonomic dysfunction in dyslipidaemia patients. Findings of the present study suggest that cardiac autonomic profile of dyslipidaemia patients with different physical activity levels varied significantly. Dyslipidaemia patients engaged in moderate and high physical activity demonstrated significantly less sympathetic activity and better sympatho-vagal balance than those engaged in low levels of physical activity; also, vagal cardiac control was significantly greater in high physical activity group. Lower levels of physical activity determined the presence of cardiac autonomic dysfunction in these patients at an optimal cut-off value of ≤1,558 Metabolic Equivalent of Tasks- min/week.

Research background and hypothesis. Lack of physical activity is influenced by a number of chronic non-infectious, mental (Corbin et al. 2001; Golden et al., 2004) and other diseases (Katzmarzyk et al., 2003). Students’ physical activity and nutrition research remains relevant, especially for those students the future profession of which is not related to physical activity and health. Research aim. The aim of the study was to estimate the relation between physical activity and health among highly and moderately active students.Research methods. All the subjects (n = 327) were grouped according to their physical activity levels. The group highly physically active students – female athletes (n = 32) and male athletes (n = 79) who were physically active more than 3000 minutes per week. The group of moderate physical activity included females (n = 47) and males (n = 169) who were physically active 600–3000 minutes per week (Ainsworth, Levy, 2004). The respondents filled in anonymous questionnaires: the International Physical Activity Questionnaire (IPAQ). The questions dealt with the time being physically active in the last seven days. The survey took place in February–April, 2012. Research results. The subjects in high physical activity group gave a subjective evaluation of their physical activity as high (53%) and moderate (32%). The subjects in the moderate physical activity group evaluated their physical activity as moderate (60%) and high (26%). All subjects in both groups indicated that their health was good. The headache symptoms, stomach, abdominal or back pains, sadness, depression, insomnia and dizziness were rare or not common at all to subjects in high (63%) physical activity group. Sadness, depression, nervous tension and irritability, and bad mood were common to subjects in moderate (59%) physical activity group. The subjects in high physical activity group had their meals three – four times per day (76%), but subjects in moderate group ate only two - three times per day (61%). Irregular lunch and dinner were common to subjects in moderate physical activity group (63%). Discussion  and  conclusions.  Research  results  showed  that  subjects  in  high  and  moderate  physical  activity groups gave correct subjective evaluations of their physical activity forms. Also subjects in high physical activity group had breakfast, dinner and supper on regular basis and they had balanced diets more often (p < 0.05).Keywords: physical activity, health, nutrition

Abstract Introduction Physical activity may reduce the development of breast cancer. Whereas hypercoagulability has been linked to adverse outcomes in breast cancer patients, the effects of physical activity on their hemostatic factors are unknown. The study aimed to assess whether long-term (1 year) physical activity can affect hemostatic factors in breast cancer patients. Methods Fifty-five women (35–75 years) with invasive breast cancer stage I/II were randomized to a physical activity intervention (n = 29) lasting 1 year or to a control group (n = 26), and analyzed as intention to treat. Fibrinogen, factor VII antigen, tissue factor pathway inhibitor, and von Willebrand factor (VWF) antigen as well as prothrombin fragment 1 + 2, the endogenous thrombin potential and D-dimer, were measured in plasma before intervention (baseline), and then after 6 and 12 months. Results Maximal oxygen uptake (measure of cardiorespiratory fitness) decreased the first 6 months among the controls, but remained stable in the intervention group. We found no significant differences between the two study groups regarding any of the hemostatic factors, except a significantly higher increase in factor VII antigen in the intervention group. The effect of the intervention on VWF was, however, significantly affected by menopausal stage, and a significant effect of the intervention was found on VWF among postmenopausal women, even after adjustment for dietary intake. Conclusion Long-term physical activity had no effect on the majority of the hemostatic factors measured, but led to increased plasma concentrations of factor VII antigen and prevented an increase in VWF concentration after breast cancer treatment in postmenopausal women. The clinical impact of these findings for risk of vascular thrombosis warrants further studies.

BACKGROUND Lack of physical activity (PA) and sedentary behaviors are leading risk factors for non-communicable diseases (NCD). Web-based interventions are effective in increasing PA in older adults and in NCD patients. In many countries a course of spa therapy is commonly prescribed to NCD patients and represents an ideal context to initiating lifestyle changes. OBJECTIVE The main objective of this study was to evaluate in NCD patients the effectiveness of an intervention combining an individual face-to-face coaching during spa therapy and, when returning home, a web- and smartphone-based PA program including a connected wrist pedometer and a connected weighing scale, on the achievement of physical activity guidelines (PAG) 12 months after the end of spa therapy. METHODS This was a 12-month, prospective, parallel-group, randomized controlled trial. Patients were enrolled during spa therapy and randomized 1:1 to intervention or control group who received usual advices about PA. From the end of spa therapy, PA, weight, waist circumference, and quality of life of the participants in both groups, were assessed by phone every 2 months. Primary outcome was meeting PAG (PA≥600 METs) at 12 months after the end of spa therapy. Secondary outcomes were: meeting current PAG at 6 months of follow-up; sedentary time, weight and waist circumference, PA and quality of life, at 6 and 12 months. Objective use data of the web-and smartphone-based PA program were collected. Analytic methods include intention-to-treat and constrained longitudinal data analyses. RESULTS The study sample was 228 patients (female : 77.2% (176/228), mean age: 62.4 years (SD 6.7), retired: 53.9% (123/228), mean BMI = 28.2 kg.m-2 (SD 4.2)). No group differences were found for any baseline variable. At 12 months, the proportion of patients achieving PAG was significantly higher in intervention group versus control group (81% vs 67% respectively, OR = 2.34 (95% CI 1.02- 5.38; P=.045). No difference between intervention and control group was found neither in achieving PAG at 6 months nor for sedentary time, weight and waist circumference, at 6 and 12 months. Regarding quality of life, the physical component subscale score was significantly higher at 12 months in intervention group versus control group (mean difference: 4.1 (95% CI 1.9-6.3; P<.001). The mean duration use of the program was 7.1 months (SD 4.5). Attrition rate during the first 2 months of the program was 20.4% (23/113) whereas 39.8% (45/113) of the participants used the program for at least 10 months. CONCLUSIONS The results showed significantly more participants meeting PAG at one year in the intervention group compared to controls. A course of spa therapy offers the ideal time and setting to implement education in PA. Digital coaching seems to be more efficient than usual coaching for increasing the level of PA and decreasing sedentariness on the long term.

Keeping a physically active lifestyle requires consistent self-regulatory effort such as action control (e.g., continuously monitoring and evaluating a behavior in terms of one’s goals). Involving the romantic partner in interventions might be particularly effective in the long run. The present study examined the long-term and transfer effects of an action control intervention in couples using text messaging for promoting target persons’ and partners’ physical activity, anthropometric measures and physical fitness 6 months post baseline. A total of 121 overweight and obese romantic couples, randomly allocated to an intervention (n = 60; information + action control text messages) or a control group (n = 61; information only) and to participating as target person or partner, completed baseline assessments (T1). 100 couples (82.6%) completed the 6-month follow-up (T3) assessment. Primary outcomes included self-reported moderate-to-vigorous physical activity (MVPA) and objective MVPA and MVPA adherence using triaxial accelerometers across a diary period of 14 days after T3. Secondary outcomes included BMI, waist-to-hip circumference and physical fitness (target persons only) using a submaximal aerobic cycle test. At T3, there were no significant between-group differences between target persons and partners with regard to their objective MVPA, self-reported MVPA, BMI, waist-hip ratio or physical fitness. No significant changes in outcomes were observed from T1 to T3; however, changes in BMI from T1 to T3 between target persons and partners in the intervention group were associated. Overall, the brief 14-days action control intervention was not effective in improving target person’s physical activity, body measures and physical fitness in the long-term. Moreover, no long-term benefits for partners emerged. While brief ecological momentary interventions might be a promising tool for short-term effects, future studies are needed to test features enhancing long-term effectiveness. Associations in romantic partners’ changes suggest that dyadic interventions can be a promising approach, as changes induced in one partner may then transfer over to the other (controlled-trials.com ISRCTN15705531).
