Cardio Respiratory Fitness

The objective of the present research was to determine whether aerobic capacity of fourteen-year-old girls is higher than that of ten-year-old girls. The research aimed to establish if the level of cardio respiratory fitness in girls decreases with age, and if their overall physical activity also decreases. A low level of cardio respiratory fitness from an early age has been confirmed in a number of studies, and it has been highly correlated with a sedentary lifestyle. Research participants were 94 fourth and eighth grade primary school girls. The variables were anthropometric measures for body height, body weight, waist circumference, and hips circumference. All the measurements were done in accordance with the International Biological Program (IBP). Body fat percentage (BF%) was also measured with the Omron (Type BF511, Japan). A multistage 20m shuttle run test was used to obtain the values for aerobic capacity, and PAQ-C questionnaire was used to estimate the level of physical activity. The results indicate that only 5% of female students meet the recommendations for physical activity while 83% engage in moderate physical activity. Statistically significant differences were determined for the variables used to estimate the aerobic capacity, with ten-year-old girls (p=0.00) having better aerobic capacity than the fourteen-year-old girls. Furthermore, ten-year-old girls were found to be significantly more physically active (p=0.00). The results of the correlation test between the aerobic capacity (VO2 max) and the overall physical activity (PA) indicate significant positive correlation (r = 0.42; p = 0.00). Girls who do not engage in physical activity at least for the recommended 60 minutes need to be directed towards various forms of healthy lifestyle with a special emphasis on everyday physical exercise that may increase their aerobic capacity.

Abstract Background Physical activity has anti-inflammatory effects and reduces morbidity and mortality in general population, but its role in the clinical, CD4/CD8 ratio and immune activation status in HIV-infected patients has been poorly studied. Methods A cross-sectional study was carried out in a cohort of 155 HIV-infected patients on stable ART to compare clinical, biochemical, CD4/CD8 ratio and immune-activation status according to their physical activity in the last two years (sedentary/low vs. moderate/intense) assessed by the iPAQ. A binary logistic regression and mixed ANOVA were performed to evaluate the impact of levels of physical activity on CD4/CD8 ratio. Results In our series 77 (49.7%) out of 155 patients were sedentary and 78 (50.3%) practiced moderate/intense physical activity. Moderate/intense physical activity was associated with lower CDC HIV-stage (p=0.046), better metabolic control (lower BMI, p=0.024; glucose, p=0.024; and triglyceride, p=0.002), higher CD3 +CD4 + T lymphocytes (p=0.016), lower CD8 + T lymphocytes (p=0.018), higher CD4/CD8 ratio (p=0.001), lower CD4 +CD8 + (p=0.026), CD4 +CD86 + (p=0.045), CD4 +HLA-DR + (p=0.011), CD8 +HLA-DR + (p=0.048) T lymphocytes and CD16 +HLA-DR + NK cells (p=0.026). Sedentary lifestyle (OR=2.12, p=0.042), CD4 nadir (OR=1.005, p<0.001) and CD8 +CD38 + T cells (OR=1.27, p=0.006) were independently associated with low CD4/CD8 ratio (<0.8). Earlier and more intense CD4/CD8 ratio recovery was observed in patients with higher physical activity in the two-year follow-up with a significant interaction between these variables: F(2, 124) = 3.31, p=0.049, partial η2=0.042). Conclusions Moderate to high physical activity is associated with beneficial health effects, improving metabolic profile and reducing chronic inflammation in patients living with HIV. Although more studies and clinical trials are needed to confirm these findings, healthy lifestyle, including at least moderate physical activity, should be recommended to HIV patients on stable ART.

AbstractBackground:Physical inactivity contributes to many health issues. The WHO-recommended physical activity for adolescents encompasses aerobic, resistance, and bone strengthening exercises aimed at achieving health-related physical fitness. Heart rate variability (HRV) and maximal aerobic capacity (VO2max) are considered as noninvasive measures of cardiovascular health. The objective of this study is to compare the effect of structured and unstructured physical training on maximal aerobic capacity and HRV among adolescents.Methods:We designed a single blinded, parallel, randomized active-controlled trial (Registration No. CTRI/2013/08/003897) to compare the physiological effects of 6 months of globally recommended structured physical activity (SPA), with that of unstructured physical activity (USPA) in healthy school-going adolescents. We recruited 439 healthy student volunteers (boys: 250, girls: 189) in the age group of 12–17 years. Randomization across the groups was done using age and gender stratified randomization method, and the participants were divided into two groups: SPA (n=219, boys: 117, girls: 102) and USPA (n=220, boys: 119, girls: 101). Depending on their training status and gender the participants in both SPA and USPA groups were further subdivided into the following four sub-groups: SPA athlete boys (n=22) and girls (n=17), SPA nonathlete boys (n=95) and girls (n=85), USPA athlete boys (n=23) and girls (n=17), and USPA nonathlete boys (n=96) and girls (n=84).Results:We recorded HRV, body fat%, and VO2 max using Rockport Walk Fitness test before and after the intervention. Maximum aerobic capacity and heart rate variability increased significantly while heart rate, systolic blood pressure, diastolic blood pressure, and body fat percentage decreased significantly after both SPA and USPA intervention. However, the improvement was more in SPA as compared to USPA.Conclusions:SPA is more beneficial for improving cardiorespiratory fitness, HRV, and reducing body fat percentage in terms of magnitude than USPA in adolescent individuals irrespective of their gender and sports activities.

Abstract Background The aim of this study was to determine whether physical activity volume and intensity in mid-childhood and early adolescence were associated with cardiometabolic risk factors at 13.5 years. Methods Participants were recruited from the Mysore Parthenon observational birth cohort. At ages 6–10 and 11–13 years, volume and intensity of physical activity were assessed using AM7164 or GT1M actigraph accelerometers worn for ≥4 days, and expressed as mean counts per day and percentage time spent in light, moderate and vigorous physical activity according to criteria defined by Evenson et al. At 13.5 years, fasting blood samples were collected; lipids, glucose and insulin concentrations were measured and insulin resistance (HOMA) was calculated. Systolic and diastolic blood pressure were measured at the left arm using a Dinamap (Criticon). Anthropometry and bio-impedance analysis were used to assess body size and composition. Metabolic and anthropometric measures were combined to produce a metabolic syndrome risk score. Results At 6–10 years, boys and girls respectively spent a median (IQR) of 1.1 (0.5, 2.0) % and 0.8 (0.4, 1.3) % of recorded time vigorously active. At 11–13 years, boys and girls respectively spent a median (IQR) of 0.8 (0.4, 1.7) % and 0.3 (0.1, 0.6) % of time vigorously active. All of the physical activity parameters were positively correlated between the 6–10 year and the 11–13 year measurements indicating that physical activity tracked from childhood to early adolescence. There were no associations between physical activity at 6–10 years and individual 13.5 year risk factors but % time vigorously active was inversely associated with metabolic syndrome score (B = −0.40, 95% CI −0.75, 0.05). Volume of physical activity at 11–13 years was inversely associated with 13.5 year HOMA and fat percentage and vigorous physical activity was associated with HOMA, fat percentage, sum of skinfolds, waist circumference and total: HDL cholesterol ratio. Vigorous physical activity was inversely associated with metabolic syndrome score (B = −0.51, 95% CI −0.94, −0.08). Conclusions Volume and intensity of physical activity in early adolescence were negatively associated with metabolic and anthropometric risk factors. Interventions that aim to increase adolescent physical activity, especially vigorous, may prevent cardiometabolic disease in later life.

Abstract Background Behaviour change interventions targeting physical activity, diet, sleep and sedentary behaviour of teenagers show promise when delivered through smartphones. However, to date there is no evidence of effectiveness of multicomponent smartphone-based interventions. Utilising a user-centred design approach, we developed a theory-based, multi-dimensional system, PEGASO Fit For Future (PEGASO F4F), which exploits sophisticated game mechanics involving smartphone applications, a smartphone game and activity sensors to motivate teenagers to take an active role in adopting and maintaining a healthy lifestyle. This paper describes the study protocol to assess the feasibility, usability and effectiveness (knowledge/awareness and behavioural change in lifestyle) of the PEGASO system. Methods We are conducting a quasi-experimental controlled cluster trial in 4 sites in Spain, Italy, and UK (England, Scotland) over 6 months. We plan to recruit 525, in a 2:1 basis, teenagers aged 13–16 years from secondary schools. The intervention group is provided with the PEGASO system whereas the comparison group continues their usual educational routine. Outcomes include feasibility, acceptance, and usability of the PEGASO system as well as between and within group changes in motivation, self-reported diet, physical activity, sedentary and sleeping behaviour, anthropometric measures and knowledge about a healthy lifestyle. Discussion PEGASO F4F will provide evidence into the cross-cultural similarities and differences in the feasibility, acceptability and usability of a multi-dimensional smartphone based behaviour change intervention for teenagers. The study will explore facilitating factors, challenges and barriers of engaging teenagers to adapt and maintain a healthy lifestyle when using smartphone technology. Positive results from this ICT based multi component intervention may have significant implications both at clinical level, improving teenagers health and at public health level since it can present an influential tool against the development of chronic disease during adulthood.

Background: Physical activity (PA) is said to be beneficial to many bodily functions. However, the effects of PA in the brain are still inadequately known. The authors aimed to uncover possible brain modulation linked with PA. Here, they combine 4 of their studies with monozygotic twins, who were within-pair discordant in PA for a minimum of 1 year. Methods: The authors performed brain imaging, brain electrophysiology, and cardiovascular and body composition assessments, and collected questionnaire-based data. The present synopsis elucidates the differences associated with differing PA history in conditions without genetic variability. They present new structural and electrophysiological results. Participants, healthy, 45 male monozygotic twins (mean age 34.5 [1.5] y) differed in aerobic capacity and fat percentage (P < .001). Results: More active co-twins showed larger gray matter volumes in striatal, prefrontal, and hippocampal regions, and smaller gray matter volumes in the anterior cingulate area than less active co-twins. Functionally, visual and somatosensory automatic change detection processes differed between more and less active co-twins. Conclusions: In monozygotic twins, who differed in their PA history, differences were observed in identifiable anatomic brain locations involved with motor control and memory functions, as well as in electrophysiological measures detecting brain’s automatic processes. Better aerobic capacity may modify brain morphology and sensory function.

Purpose – The purpose of this paper is to evaluate Feel WonderFull Fitness (FWF), a program adhering to the Health At Every SizeTM (HAES) paradigm, on larger women's physical activity and psychosocial health. FWF was tailored to overcome barriers based on weight bias. Design/methodology/approach – The study compared “overweight” and “obese” women in FWF to those not currently enrolled in formal exercise programs. Controls were divided into low physical activity (LPA) and moderate physical activity (MPA) conditions based on pretest exercise level. Outcome measures were collected at pretest and three months later at posttest. Findings – FWF participants had the greatest gains in physical activity and demonstrated significantly greater improvements in depression than the LPA group. FWF and the MPA group showed more improved scores on perceived body attractiveness than the LPA group. Scores on an eating disorders measure improved for all groups, but somewhat more so for the FWF group. Improvements occurred in the absence of weight loss or decreases in body mass index and body fat percentage. Research limitation – The study was based on a small, homogenous sample using a quasi-experimental design. Practical implications – The study illustrates HAES strategies that practitioners might incorporate into various health and fitness settings. Social implications – The study highlights weight bias as a social justice issue and as a barrier to physical activity participation for larger women. Originality/value – The study adds to a growing body of literature evaluating HAES approaches, with HAES representing a novel alternative to weight-loss interventions for improving psychosocial health among larger women. It also contributes to the literature on weight bias that has been understudied relative to bias based on other areas of difference.

SummaryStudy aim: the aim of this study was to determine how body height, body weight, and moderate physical activity affected postural stability in young schoolchildren.Materials and methods: the study population consisted of 148 primary school pupils. To assess postural stability, we used the CQStab2P stabilometric equipment (the bi-platform version), and an assessment of physical activity was conducted via questionnaire.Results: the study revealed that both greater body weight and greater body height positively affected postural stability in the studied population. We found a low, yet significant correlation regarding postural stability in children who attended sports classes. In the cases of path length and mean amplitude of sway with eyes closed, the children who were more active in sports had better vertical postural stability. We did not find any relationships between static balance and the number of sports classes attended in a week, or with participating in extra academic classes.Conclusions: 1. Children’s postural stability improved with age. 2. Children who took part in sports classes had better body balance. 3. The number of sports classes attended did not correlate with better postural stability.
