The aim of this study was to investigate the effects of relations between body composition parameters and lung functions including VC, FVC, FEV1, FEV1/VC, FEV1/FVC after 6-months callisthenic exercise program in healthy women.
The tenth of the study's participants who had the most para-dichlorobenzene in their blood--more than 4.4 micrograms per liter--had about 4 percent lower FEV1 values than did the tenth of participants with the lowest blood concentrations--averaging 0.1 [micro]g/1.
Lung function test (FEV1 and PEF) were completed one day before treatment and one day post-treatment.
The risk for developing vascular dementia was increased with low PEF but not FVC or FEV1, Dr.
Sample Size: Sample size was calculated for proportions using PASS version 15.0 software, and using reported frequency of FEV1 abnormalities of 25% in patients of HCV.12 It was also calculated for one Proportion using parameters of P0 = 0.5; P1 = 0.25; Power = 0.95; Alpha = 0.01; n = 65.
Table 3 shows that in obese group showed significant negative correlation of BMI with FVC (r = -0.2563), FEV1 (r = -0.3659), and PEFR (r = -0.4526).
The values of Forced Expiratory Volume in first second (FEV1) less than 80% of the expected value and ratio of forced expiratory volume in first second to the forced vital capacity less ([FEV.sub.1]%) than 0.7 (70%) after post-bronchodilator inhalation were included in this study.
The following parameters of the pulmonary function test were measured: (a) forced expiratory volume in the first second (FEV1) pre- and postadministration of a bronchodilator, (b) forced vital capacity (FVC), and (c) peak expiratory flow (PEF).
The study confirmed a statistically highly significant decline in FVC, FEV1, FEF 25-75%, PEFR and FEV1/FVC ratio among different types of welders.
The difference in forced vital capacity (FVC) and forced expiratory volume (FEV1) was highly significant between Group-1 and Group-2 and between Group-1 and Group-3 (P < 0.001).
Spirometry: Spirometry was conducted using SPIROVIT SP-1 (Schiller, Switzerland) to assess lung function test parameters including "Forced Vital Capacity (FVC), Forced Expiratory Volume in First Second (FEV1), Forced Expiratory Ratio (FEV1/FVC%), Peak Expiratory Flow (PEF), Forced Expiratory Flow-25% (FEF25%); Forced Expiratory Flow-50% (FEF50%); and Forced Expiratory Flow-75% (FEF75%)".
