Capacidades físicas y su relación con la actividad física y composición corporal en adultos (Physical capacities and their relationship with physical activity and body composition in adults)

La práctica regular de actividad física sugiere un aumento de la condición física y una mejora de la composición corporal; sin embargo, a pesar de que las personas cumplen con las directrices propuestas no logran obtener buenos indicadores de condición física los cuales brindan más información acerca de la salud. Objetivo: Analizar la relación entre las capacidades físicas de fuerza prensil, potencia en piernas, consumo máximo de oxígeno, actividad física con la composición corporal en adultos. Metodología: Estudio descriptivo correlacional de corte transversal, se evaluaron 100 adultos, se valoró fuerza prensil con dinamometría, potencia en piernas con tres tipos de saltos, VO2máx, la actividad física por cuestionario IPAQ y la composición corporal con bioimpedancia eléctrica. Resultados: Los varones poseen valores mayores de capacidades físicas, masa magra y actividad física realizada con mayor intensidad en comparación con las mujeres; los resultados muestran una estrecha relación entre la práctica de actividad física realizada con intensidades moderadas y altas en relación a las capacidades físicas de fuerza prensil y potencia en piernas en aquellas personas sin peso bajo u obesidad; Además, en todas éstas, mediante el análisis Post Hoc, se encontró que las diferencias se presentan entre la actividad baja en comparación con la vigorosa y en la moderada con respecto a la vigorosa. Conclusiones: Personas con normo y sobrepeso muestran mejores capacidades físicas, así como valores elevados de actividad física, mientras que altos índices de grasa corporal total y un IMC elevado son un factor determinante para el desarrollo de las mismas. Abstract: The regular practice of physical activity suggests an increase in physical condition and an improvement in body composition, despite the fact that people comply with the proposed guidelines, they are unable to obtain good indicators of physical fitness, which provide more information about the Health. Objective: To analyze the relationship between physical capacities of grip strength, leg power, maximum oxygen consumption, physical activity and body composition in adults. Methodology: Cross-sectional correlational descriptive study, 100 adults were evaluated, grip strength was assessed with dynamometry, leg power with three types of jumps, VO2max, physical activity by IPAQ questionnaire and body composition with electrical bioimpedance. Results: Men have higher values of physical capacities, lean mass and physical activity carried out with greater intensity compared to women; The results show a close relationship between the practice of physical activity carried out with moderate and high intensities in relation to the physical capacities of grip strength and power in the legs in those without underweight or obesity; In addition, in all of these, by means of Post Hoc analysis, it was found that the differences are presented between low activity compared to vigorous activity and moderate activity compared to vigorous activity. Conclusions: Normal and overweight people show better physical capacities as well as high levels of physical activity, while high levels of total body fat and a high BMI are a determining factor for their development.

BACKGROUND Commercially acquired wearable activity trackers such as the Fitbit provide objective, accurate measurements of physically active time and step counts, but it is unclear whether these measurements are more clinically meaningful than self-reported physical activity. OBJECTIVE The aim of this study was to compare self-reported physical activity to Fitbit-measured step counts and then determine which is a stronger predictor of BMI by using data collected over the same period reflecting comparable physical activities. METHODS We performed a cross-sectional analysis of data collected by the Health eHeart Study, a large mobile health study of cardiovascular health and disease. Adults who linked commercially acquired Fitbits used in free-living conditions with the Health eHeart Study and completed an International Physical Activity Questionnaire (IPAQ) between 2013 and 2019 were enrolled (N=1498). Fitbit step counts were used to quantify time by activity intensity in a manner comparable to the IPAQ classifications of total active time and time spent being sedentary, walking, or doing moderate activities or vigorous activities. Fitbit steps per day were computed as a measure of the overall activity for exploratory comparisons with IPAQ-measured overall activity (metabolic equivalent of task [MET]-h/wk). Measurements of physical activity were directly compared by Spearman rank correlation. Strengths of associations with BMI for Fitbit versus IPAQ measurements were compared using multivariable robust regression in the subset of participants with BMI and covariates measured. RESULTS Correlations between synchronous paired measurements from Fitbits and the IPAQ ranged in strength from weak to moderate (0.09-0.48). In the subset with BMI and covariates measured (n=586), Fitbit-derived predictors were generally stronger predictors of BMI than self-reported predictors. For example, an additional hour of Fitbit-measured vigorous activity per week was associated with nearly a full point reduction in BMI (–0.84 kg/m2, 95% CI –1.35 to –0.32) in adjusted analyses, whereas the association between self-reported vigorous activity measured by IPAQ and BMI was substantially smaller in magnitude (–0.17 kg/m2, 95% CI –0.34 to –0.00; P<.001 versus Fitbit) and was dominated by the Fitbit-derived predictor when compared head-to-head in a single adjusted multivariable model. Similar patterns of associations with BMI, with Fitbit dominating self-report, were seen for moderate activity and total active time and in comparisons between overall Fitbit steps per day and IPAQ MET-h/wk on standardized scales. CONCLUSIONS Fitbit-measured physical activity was more strongly associated with BMI than self-reported physical activity, particularly for moderate activity, vigorous activity, and summary measures of total activity. Consumer-marketed wearable activity trackers such as the Fitbit may be useful for measuring health-relevant physical activity in clinical practice and research.

Significant Difference

Background: Physical inactivity and overweight are leading risk factors for global mortality, responsible for 6% and 5% of deaths worldwide due to chronic non communicable diseases. It is well established that regular moderate or vigorous-intensity exercise lowers the risks and symptoms associated with the co-morbidities of obesity. The stress involved in meeting responsibilities of becoming a physician may adversely affect the exercise habits of students. So, the current study aimed to study physical activity and its relation with body composition among under-graduate medical students.Methods: It was a cross-sectional study among 282 medical students. International Physical Activity Questionnaire (IPAQ) Short form was used to measure total physical activity (PA) and body composition parameters including Waist circumference, WHR, BMI, Body Fat% were assessed and analyzed using SPSS version 21.Results: Out of 282 medical students 33%, 45.3%, &21.3% were involved in low, moderate and high physical activity. ANOVAs between different levels of physical activities according to IPAQ categories showed significant difference for Waist Hip Ratio (F:3.8; p=0.02) and Body Fat percentage (F=5.7; p=0.00). There was an inverse and statistically significant correlation between physical activity and Waist circumference, Body Fat% and Waist –Hip Ratio.Conclusions: Medical Students involved in higher level of physical activity have significantly lower body Fat% level and WHR as compared to those belonging to lower and moderate activity group thus there is a need to actively promote physical activity among medical students.

Objectives. To highlight the pattern of vigorous physical activity among freshmen university students and to evaluate the association between sociodemographic factors, perceived barriers, support factors, sedentary behaviours and body mass index. Methods. A cross-sectional study was conducted on Mansoura University students at the beginning of the academic year 2008 - 2009. A total of 500 freshmen students were selected by systematic random sample. Participants responded to the short form of International Physical Activity Questionnaire and other questions. Results. The study revealed that the prevalence of vigorous activity among the students was 9.8% (N=49) versus 90.2% (N=451) for mild and moderate activity. Body-related barriers were significantly higher among those reporting mild and moderate activities as shyness from others when doing exercise (6.9% versus 0.0%) and shyness from body looks in front of people (14.6% versus 4.1%). Lack of equipment was also perceived to be a barrier (31.0% versus 16.3%), for those doing mild to moderate versus vigorous, respectively. A significantly higher proportion of persons doing vigorous activity reported the influence of support factors such as perceived benefit for health (53.1% versus 33.7%), encouragement from others (53.1% versus 30.4%) and participation from others (51.0% versus 23.9%), compared with the more sedentary students. The majority of both groups spent <4 hours daily in front of a computer, but the overall proportion was significantly higher among those only reporting mild and moderate activity (88.0% versus 63.3%). Conclusion. The prevalence of most of the barriers studied was higher among those reporting mild and moderate activities and support factors were higher among those reporting vigorous activity. These results highlight the importance of environmental factors, social norms and intra-personal factors in determining the pattern of activity among Egyptian freshmen university students.SAJSM, vol 23 No. 4 2011

Background:Physical inactivity is now a public health priority because of the high rates of inactivity observed worldwide. Achievement of physical activity guidelines could be attained with vigorous, moderate, or both activities combined. Our aim was to explore the prevalence and correlates of compliance with vigorous physical activity guidelines (CVAG).Methods:Cross-sectional population-based survey in Pelotas, a southern Brazilian city, including 3182 adults (≥ 20 years). The short version of the International Physical Activity Questionnaire was applied by face-to-face interviews. CVAG was defined as at least 60 min/wk of vigorous activity.Results:Only 29% of the subjects achieved the vigorous activity threshold. Women, older adults, individuals with low BMI (< 18.5 kg/m2) or obese (≥ 30 kg/m2) were less likely to present CVAG. Compliance with moderate activity guidelines was associated with a higher likelihood of CVAG.Conclusions:Concurrent promotion of moderate and vigorous physical activities is warranted in terms of public health.

The Impact

Physical activity (PA) during pregnancy is beneficial for mother and child. Little is known regarding the effects of PA on specific adipokines/myokines and their impact during pregnancy. This study investigates the correlation between PA during late pregnancy, body composition, and maternal levels of leptin, IL-6, and TNF-α at delivery. In a cross-sectional study of 91 pregnant participants (mean age 33.9 ± 4.6 years) without gestational diabetes mellitus or preeclampsia, anthropometric data and blood samples were taken at delivery. PA during the third trimester was measured via the Pregnancy Physical Activity Questionnaire. Activities were ranked by intensity: sedentary (<1.5 metabolic equivalent (METs)), light (1.5–3.0 METs), moderate (3.0–6.0 METs), and vigorous activity (>6.0 METs). Leptin at delivery correlated positively with body composition and negatively with light PA intensity. Sedentary behaviour showed a positive correlation with IL-6 levels at delivery. Moderate activity during the last trimester, sedentary activity levels, and body composition had the greatest influence on maternal IL-6 at delivery. Completed weeks of pregnancy, moderate and light PA, and sedentary activity had the greatest influence on maternal TNF-α at delivery. PA during late pregnancy potentially affects circulating (adipo-)/myokines. Further studies are needed to examine causal relationships and the impact on maternal and new-born health.

Adolescents And Adults

Measures of body fat and lean mass may better predict important clinical outcomes in patients with cystic fibrosis (CF) than body mass index (BMI). Little is known about how diet quality and exercise may impact body composition in these patients. Dual X-ray absorptiometry (DXA) body composition, 24-h dietary recall, and physical activity were assessed in a cross-sectional analysis of 38 adolescents and adults with CF and 19 age-, race-, and gender-matched healthy volunteers. Compared with the healthy volunteers, participants with CF had a lower appendicular lean mass index (ALMI), despite no observed difference in BMI, and their diets consisted of higher glycemic index foods with a greater proportion of calories from fat and a lower proportion of calories from protein. In participants with CF, pulmonary function positively correlated with measures of lean mass, particularly ALMI, and negatively correlated with multiple measures of body fat after controlling for age, gender, and BMI. Higher physical activity levels were associated with greater ALMI and lower body fat. In conclusion, body composition measures, particularly ALMI, may better predict key clinical outcomes in individuals with CF than BMI. Future longitudinal studies analyzing the effect of dietary intake and exercise on body composition and CF-specific clinical outcomes are needed.

Introduction: People with stroke commonly show low levels of physical activity and reduced functional capacity, independent of the severity of the impairments. The use of simple measures that are able to produce transferable information from clinical practice to life in society is crucial within clinic contexts. Objective: To compare the functional capacity of patients with chronic stroke based upon their physical activity levels. Methods: For this cross sectional study, functional capacity and levels of physical activity were assessed by the Duke Activity Status Index (DASI) and the adjusted activity score (AAS) of the Human Activity Profile (HAP), respectively. One-way analysis of variance (ANOVA), followed by LSD post-hoc tests were employed to investigate differences between the physical activity groups regarding their DASI scores. Results: Fifty-one individuals with mean age 58.8 ± 13.5 and a mean time since the onset of stroke of 25.5 ± 13.9 months participated. According to their HAP AAS, 18 individuals were classified as impaired, 28 as moderately active, and five as active. Between-group differences were observed for the DASI scores [F(2,48)=13.72; p < 0.01]. Conclusion: Increases in functional capacity were observed with increases in physical activity levels.Key-words: stroke, motor activity, activities of daily living.

ObjectiveAssociations between self-reported sleep duration and obesity indices in children are well recognised; however, there are no studies on associations between objectively measured other sleep parameters and physical activity with body composition in preschoolers. Therefore, the aim of this study was to determine the associations between sleep parameters and moderate-to-vigorous physical activity (MVPA) with body composition indices in preschoolers using objective measures.DesignA cross-sectional study.ParticipantsThe study group consisted of 676 children aged 5–6 years, who were enrolled in kindergartens in the 2017/2018 school year.Outcome measuresSleep parameters and MVPA were measured using accelerometers for 7 days. Bioelectrical impedance analysis was used to estimate body composition.ResultsSleep duration and sleep efficiency were inversely associated with body fat percentage (BFP) (β=−0.013 and β from –0.311 to −0.359, respectively) and body mass index (BMI) (β from −0.005 to −0.006 and from −0.105 to –0.121, respectively), and directly associated with fat-free mass (FFM) (β from 0.010 to 0.011 and from 0.245 to 0.271, respectively) and muscle mass (β from 0.012 to 0.012 and from 0.277 to 0.307, respectively) in unadjusted and adjusted models. BFP was inversely associated with MVPA and positively associated with number of awakenings and sleep periods. Number of sleep periods was inversely associated with FFM, and positively with BMI and muscle mass. Correlation matrix indicated significant correlation between BFP, FFM and muscle mass with sleep duration, sleep efficiency, number of sleep periods and MVPA.ConclusionsPeriodic assessment of sleep parameters and MVPA in relation to body composition in preschool children may be considered, especially in those who are at risk for obesity.

Introduction: In our daily life, arm activities, whether supported or unsupported play a major role. Both simple and omplex activities require the muscles, namely trapezius, pectoralis minor, scalene, and intercostals, to participate in arm positioning. These muscles also enact as the accessory respiratory muscles. Therefore, arm elevation increases the load on these muscles and they fail to perform dual activities, resulting in arm fatigue and a feeling of dyspnoea in healthy individuals as well as in chronic obstructive pulmonary disease patients. Various upper limb exercise tests were designed to measure this impairment, one of them being the six-minute peg board and ring test. The aim of the study is to derive a reference value for the six-minute peg board and ring test among healthy Indian population (Mangalore) from the age of 20-70 years of either gender. Also, to find a correlation among the number of rings and body mass index, arm length, arm and forearm circumference, the strength of shoulder and elbow flexors-extensors, grip strength of both sides and level of physical activity.Methods: Participants performed two tests, thirty minutes apart. They were asked to load as many rings as possible in 6 minutes. Arm length, arm and forearm circumference were measured with a measuring tape. Shoulder and elbow flexors-extensors were assessed using a handheld push-pull dynamometer. Grip strength was measured with the Jamar hand-held dynamometer. Level of physical activity was assessed using International Physical Activity Questionnaire long form.Results: The samples consisted of 450 healthy individuals between the age of 20-70 years. Reference values for each age group for both genders were reported. We found that age was correlated with the six-minute peg board and ring test score (p<0.05). We also found a correlation between the strength variables and the test results (p=0.001). However, no correlation was found between the arm length, arm and forearm circumference and the level of physical activity with the number of rings.Conclusion: In this study, we derived a reference value for the six-minute peg board and ring test. There was a correlation amongn age, strength variables and the number of rings.
