As the amount of correlation increases, then the first eigenvalue will slowly start to id, and the later ones will decrease to whats 420 mean in text. Entrenamiento total. Adipose tissue is a determining variable in the difference between genders with respect to oxygen consumption, as noted in Table 4given that a reason why women present less oxygen consumption is precisely because of their higher percentage of body fat For binary and ordinal corrleation, we used kappa index and weighted kappa index tests. Nephrol Dial Transplant ; In post-dialysis what is a good correlation, the mean weighted kappa index was 0. However, the values for phase angle were statistically different. This last aspect was negatively associated to the number of sessions and hours per week dedicated to physical exercise, permitting that inference that with higher weekly frequency and number of what is a good correlation of physical exercise, the i of body fat are reduced.

Correlation of anthropometric variables, conditional and exercise habits in activite olders. Objective: This study sought to correlate the anthropometric and functional variables, and exercise habits in a group of elderly adults who regularly attend exercise programs. Method: participation of subjects between 60 and 85 years of age, from 13 regions of Colombia. Anthropometric and functional assessment was conducted as a questionnaire on exercise habits.

Results: negative correlations were shown between exercise habits and body fat and positive correlations between hand strength and VO2 max. Conclusions: The functional capacity is influenced by increased age and body fat. With higher frequencies of physical exercise, VO2 max. Método: participación de sujetos entre 60 y 85 años de edad, procedentes de 13 regiones de Colombia. Conclusiones: la capacidad funcional se ve influenciada por el incremento de la edad y grasa corporal.

Aging implies structural and functional changes in humans; these appear in physical and mental aspects, generating deterioration that is reflected in lower capacity to perform basic activities of daily life BADL like eating and showering; in advanced activities of daily life AADL like walking and climbing stairs; inabilities that generate functional limitation, being a factor that causes detriment in the quality of life in the enderly 1.

Added to these inevitable modifications is a phenomenon regularly present in the elderly like overweight conditions, which if not controlled, worsens problems of functionality and independence that impact upon their morbidity and mortality. But it is also true that physical exercise programs developed with scientific rigor, bearing in mind anatomical and functional changes present in the elderly population, impact upon their health and functionality by generating increased muscle mass, strength, bone density, flexibility, Vo2 max.

The variables determining physical condition are related to movement, that is, a person in good physical shape can perform activities with ease and autonomy; hence, aerobic capacity, body composition, strength, muscular endurance, flexibility, and balance, are essential an individual's health 3. This study sought to identify existing correlations among anthropometric and functional variables and physical exercise habits in a group of elderly adults who regularly attend physical exercise programs.

Instruments : for the anthropometric evaluation, the following were used: Martin type GMP anthropometer with cm capacity, 1-mm precision, Harpenden fat folds calibrator with an 8-mm capacity, 0. Body density was calculated via the Jackson and Pollock equation 5 and the percentage of fat via the Siri equation 6. The functional variables were evaluated with ECFA-INEFG tests by Camiña 7evaluating abdominal muscle strength with a test of 75 torso flexions during a three-minute period; manual pressure strength through manual dynamometry with a Takei dynamometer Smedly III model; range of articular what is a good correlation through anterior flexion of the torso with knees extended in sitting position Wells and Dillon test ; postural balance with can case studies show cause and effect monopodal balance test with vision for one minute; Vo2max from the Rockport test by walking a Fenstermarker mile 8.

In exercise habits, a self-administered questionnaire was used and with support by the study conducted by Osorio et al. Procedure : data was collected during the Olympiads for the Elderly, held in Palestina, Caldas, between the 24 th and 28 th of August The inclusion criteria were: being older than 60 years of age and having what is a good correlation engaged in a physical exercise program during at least the last year.

Authorization was obtained from the bioethics committee from the Faculty of Health Sciences at Universidad de Caldas, complying with regulations in Resolution ofissued by the Colombian What is a good correlation of Health; permission from delegates and informed signed consent from the participants were also obtained. Data analysis : the correlation coefficient was determined through Spearman, being the most appropriate method when relating parametric and non-parametric variables, as in this case.

Correlation was established with the following criteria: 1. Also, a multivariate regression model was made for the Vo2max. Data were analyzed via the SPSS program v. In the distribution by age groups, there are fewer participants as age increases, as noted in Table 1. In the correlation of variables from Table 2the highest value was presented between BMI and hip circumference. Percentage of fat showed positive correlation with hip and waist circumference.

Vo2 max. Torso flexibility was negatively correlated to the waist circumference and age of the individuals. Manual pressure strength was positively correlated to the number of years engaged in sports activities, weekly frequency, and number of hours of physical exercise; likewise, pressure strength was negatively associated to static balance and age.

Static balance was positively associated to Vo2 max. This last anthropometric component was negatively associated to the number of hours and weekly sessions of physical exercise. As noted in Table 3a multivariate regression model was estimated for Vo2 max. All the coefficients of the model Bi are significantly different from zero, which indicates that the predictive variables explain Vo2 max; likewise, the global predictive model is highly significant.

Additionally, the model fulfills all the assumptions of the classical model normality of residuals, homocedasticity, and lack of autocorrelation and absence of multicollinearity. Percentage of fat was negatively correlated to Vo2 max. It must be highlighted that Adipose tissue is a determining variable in what is a good correlation difference between genders with respect to oxygen consumption, as noted in Table 4given that a reason why women present less oxygen consumption is precisely because of their higher percentage of body fat This last aspect was negatively associated to the number of sessions and hours per week dedicated to physical exercise, permitting that inference that with higher weekly frequency and number of hours of physical exercise, the levels of body fat are reduced.

These previously mentioned findings are coherent with the fundamentals of exercise physiology, where it has been shown that to reduce body fat, calorie intake must be reduced and energy expenditure increased through physical exercise, which - if possible - must be of low what is a good correlation, long duration and developed under an appropriate weekly frequency. This is also corroborated by Anton et al. The results of the current study call for reflection upon the pertinence of creating physical exercise programs with greater weekly frequency to that reported by the general average of subjects, given that this factor is related to diminished fat, which contributes to lower risks of functional limitation1 and cerebrovascular disease The BMI was negatively correlated to Vo2 max.

These causes support the reason why children have higher relative oxygen consumption as compared to adults. Hip circumference showed good correlation with BMI, percentage of fat, and waist circumference, variables related to body example of a cause and effect text structure and which permit predicting changes in fat at general levels These results reveal that hip circumference is determining in predicting functionality in this age group, especially when the results of this variable showed negative correlation with Vo2 max.

This indicates that subjects with good levels of strength have greater ease to carry out activities that imply vigor and energy expenditure, which for this specific case will have enabled their covering a longer distance in the Rockport test; hence, having a favorable Vo2. These results coincide with the study by Osorio et al. Regarding the positive correlation among manual pressure strength and the variables of number of years practicing sports activities, amount of sessions and hours per week of physical exercise, diverse authors support the direct relationship among these aspects; initially, Frontera et al.

Likewise, Ramírez JF. Age was what are examples of risk factors in food associated to manual strength, Vo2 max. These results were expected, given that although exercise contributes what is my common law wife entitled to slow down organic involution, it is inevitable that with increased age, deterioration occurs in the structural and functional levels, even in individuals who engage in physical exercise.

Balance influences one of the main dysfunctionality phenomena in elderly adults like falls, which are related to morbidity and what is a good correlation in the elderly It is worth noting that balance was negatively correlated to the percentage of fat and hip circumference, which are related to levels of overweight and obesity in an older population according to Moreno and Ramos 22being counterproductive to preserving balance It is important to highlight that the static balance has a positive association with Vo2 max.

This variable was also positively associated to Vo2 max. It can be seen in the regression model for Vo2 what is a good correlation, in Table 3that with greater age and hip circumference there is lower oxygen consumption, as with greater manual pressure strength this variable increases, which is coherent with findings shown in the correlation of variables, inasmuch as hip circumference and age present negative correlation with Vo2 max. Also, the percentage of fat is inversely proportional to oxygen consumption according to Ogawa et al.

A favorable relationship was observed of physical exercise with increased strength and diminished body fat. Although it is true that a negative association was found between age and functional capacity, strength was favorably correlated to engaging in physical exercise, which at the same time was associated negatively to body fat, favoring Vo2 max. Strength, aerobic resistance, balance, and flexibility are variables that should be transversally developed and what is a good correlation an appropriate weekly frequency in physical exercise programs to what is a good correlation the functional capacity of the elderly.
