Effects of Moderate Intensity Interval Training in workers suffering from Restrictive Lung Diseases involved in Polluted environment at Iron Ore Mine

Impaired lung function (Restricted) is the one of major problems in those workers that are exposed to occupational dust. As regards, evidence of the benefit of pulmonary rehabilitation in restrictive lung disease is limited. Forever, the purpose of this study was to investigate the effect of 12 weeks of moderate intensity periodic exercises on the basic parameters of pulmonary function in practitioner patients with Restrictive pulmonary disease (RLD) working in polluted environment of Iron ore mine.

To do this 30 patients with restrictive pulmonary disease (average degree), were selected from workers of Sangan Iron mine in Khaf city and randomly divided into two groups: 1) periodic exercise with moderate intensity and 2) control. The study period was 12 weeks (3 sessions per week). During this period, the travelled Time, increased progressively from 10 to 32 minutes. At the beginning and end of the study, pulmonary indices (FEV1 and FVC) and functional (Test for maximum aerobic speed (MAS)) as well as Rate of Perceived Exertion (RPE) was performed and used for final statistical Analysis.

The results showed the respiratory parameters (FEV1 and FVC) in groups 1 significantly increased (p˂0.001). Moreover, mean travelled distance in MAS test significantly increased in experimental group (P<0.0001). Rate of Perceived Exertion (RPE) also decreased significantly after intervention period.

Based on our research results, the moderate intensity periodic exercises improved the cardio-pulmonary performance indicators of RLD workers. Also this protocol can be used in another jobs exposed with pollution
