Peak Expiratory Flow Rate

Thirteen healthy undergraduate students at the University of Brighton (8 males, 5 females; mean ± SD, age: 19.2 ± 1.5 years; body mass: 67.4 ± 16.1 kg; height: 177 ± 28.2m) were briefed with the study procedure. Their anthropometric data was collected, along with a medical questionnaire and their consent to participate in the study. All of the participants were familiar with the laboratory testing procedures.

1. Dependent Variable. respiratory volumes 2. Independent Variable. level of physical activity [resting or exercising] 3. Controlled Variables. height; age; sex 4. Which respiratory volume was calculated? Breating rate, TV, ERV, and IRV. 5. What was the purpose of the nose clip? the nose clip was used for the lung function testing to prevent leakage with

Nevertheless, the unidentified person may have had malnutrition, which would lead to stunted growth in certain areas that happened to not affect the humerus or femur. Back to how the results came out, the students plugged the measurements into certain formulas according to race and gender. By having these differences in formula, it made it more accurate because each race and gender, due to genetics, can make the height different.

Statistical Analysis. The data analysis that was provided, shows percentages of obese children at baseline and after the 12 months period. Furthermore, the logistic regression analysis conducted on the 3 serum parameters describe the changes at the 12 months mark to address the research questions about hs-CRP. Study constructed means of measuring samples by differentiating between gender and POW. Although there were no specific instrument developed for this particular study. The researchers were able to drawn blood samples for the latex-enhanced immuno-nephelometric apparatus (BN II analyzer) to measure serum parameter proteins in the plasma. The collection process was conducted in a constant manner as the researchers collected the samples at the same time during both times. With the accuracy and precision of the instrument set to detect CRP at 0.02 mg/dL. POW were obtained by measuring weight and height and obesity/percentage overweight was described as POW>20%. Never the less, mentioned measuring techniques for height and weight were not discussed other the than using weight scale and measuring meter scale. McNemar statistical analysis was used to determine the relation between gender and hs-CRP. And odds ratio were used then to link relation between obesity and serum blood cholesterol levels, Age, Sex (objective Variables). The logistic regression analysis used had 95% confidence level of the odds ratio of log CRP. Data revealed sex different is

In the Past AIx has been reported as changing linearly with age i.e. as age increases so dose AIx [77, 78]. However, two more recent studies [79, 80] have shown changes in AIx are non-linear. It was shown that any change in AIx is more marked in younger individuals (<50) and age had a greater effect when below the age of 50 (Fig 4). It has also been demonstrated that low birth weight gives increased risk of elevated AIx in adolescence [81]. However the literature disagrees what AIx does over the age of 60, one study has shown a gradual decline in AIx past the age of 60 [79], where as another reports a plateau past the age of 60, It is unclear whether this is an effect of sample size or a difference in demographic between the studies [80]. It should also be noted that AIx is commonly higher in females [82].

The information I gathered allowed me to calculate my waist circumference to height ratio, which resulted to be 0.4923. My score of 0.4923 yielded me a fitness classification of acceptable with a very low disease risk. To be placed in the category I was placed in, women must have a ratio between the range of 0.4-0.5, if its below or above this range then it would result in a category classification of take care and increased risk of disease.

Now you need to take into consideration yourself with regard to fitness along with height:

Necessary increase in ventilation to maintain blood gas homeostasis during exercise was compromised in some individuals resulting in a high work of breathing. When these ventilatoy demands exceed the capacity for the lung and chest wall to generate flow and volume, expiratory flow limitation can develop which may result in diaphragm fatigue. Expiratory flow limitation (EFL), is an important physiological phenomenon since it is associated with dynamic hyperinflation, which increases the work of breathing and causes dyspnea and potential exercise

A wide range of different levels and body adiposity of moderate to vigorous physical activity in children with the range from twenty-seven to two hundred thirty-one and having multiple frequencies of bioelectrical impedance analysis. The body mass index in children and the fat mass percentage is an operating characteristic that curves each count per minute and the physical activity have shown that the children did not meet the required body mass with resulted an increase in obesity and overweight children and with the risk of having a mass excess of

A healthy male volunteered to participate in the study. His age was 24 years old, height 180cm, weight 66.4kg, body mass index (BMI) 20.5kg/m2 and VO2max 57.7mLkg-1min-1. Participant was required to complete medical-history questionnaires. Participate had moderate levels of physical activity. Participant gave his written informed consent.

It is expected that PEFR will vary significantly between individuals due to the many different factors that may affect pulmonary function. Therefore, it is important to consider an individual’s characteristics when determining the normality of their PEFR measurement. Two such characteristics that appear to impact PEFR are gender and fitness levels.

Even though we humans are all same species, some difference exist between nationality, race, or gender. Height is one example, which can be mentioned as a difference between people. Human height differs in countries, gender, and age. For example, the average height of Japanese are around 170cm for men and 158cm for women. Compared to these numbers, the average height of men are 183cm and 169cm for women in the Netherlands (“Disabled World”). As being seen in numbers, most people have a stereotype that Japanese are tend to be small compared to people in other countries. Genetic factors and environmental factors can be considered as the reasons of this phenomenon. Although our heights are determined by those factors, people can enhance their

Studies propose that serum cystatin C is able to predict GFR better than serum creatinine in adult and paediatric populations. The GFR estimated using Cystatin C are independent of age and body composition and are therefore useful in both children and adults, while GFR estimated using creatinine depends on age and obesity. Also, studies reveal that cystatin C methods of analysis may offer better precision than serum creatinine assays 23, 24, 25, 26.

Contrary to our findings, this study’s analysis provided evidence for sex differences that could contributions to an energy balance, patterns of EI and weight changes. However, this study has used different methodologies and subject group to carry out their investigation which may have led to this variance in results.
