“…Thus, absolute HR measurements may be meaningless if they do not take into consideration individual characteristics. To avoid this issue, a relative HR (RHR) can be expressed in relation to individual maximal HR (HRmax) and resting HR (HRrest) (Rodahl, 1989;Vitalis et al, 1994):…”

The monitoring of construction workforce physical strain can be a valuable management strategy in improving workforce productivity, safety, health, and quality of work. Nevertheless, clear relationships between workforce performance and physical strain have yet to be established. An exploratory investigation of the relationship between task level productivity and physical strain was conducted. Nine participants individually performed a four-hour simulated construction task while a wearable physiological status monitor continuously assessed their physiological condition. Heart rate, relative heart rate, and breathing rate were utilized as predictors of physical strain, and task level-single factor productivity was used as an index of productivity. Numerous regression models were generated using the collected data. This investigation initially unsuccessfully attempted to establish a relationship between physiological condition and productivity at the individual worker level. However, an analysis of the regression models showed that there is a relationship between productivity and either heart rate or relative heart rate at the group level, and that this relationship is parabolic. Breathing rate was proved to not be a significant predictor of productivity. Research results significantly improve understanding of the relationship between work physiology and task productivity. Researchers and practitioners may use the tested monitoring devices, analysis methods, and results to design further applied studies and to improve workforce productivity.

“…From the comparative study of CSI of china clay mine workers with that of other industrial workers, it was noted that the stress was much higher in mine workers than that of the car assembly workers [32] and little higher than steelworkers [33]. Such variation of the CSI among different group of industrial workers might be due to difference in the degree of severity of job, environmental conditions and also duration of activity [22].…”

Background: Several risk factors are associated with cardiopulmonary stress of industrial workers. Most important factors are job strain, job demand, physical effort, work station environment etc. In India, study on occupational cardiopulmonary stress among china clay miners is scanty. Objectives: The present study was aimed to evaluate the cardiopulmonary stresses of the china clay mine workers. Methods: The investigation was carried out on male workers from different china clay mines in the Birbhum district, West Bengal. The cardiovascular stress was evaluated by noting pulse rate of the subjects both during rest and during performance of different types of mine tasks. The cardiovascular stress index (CSI) was evaluated in different mine task. The work rest cycle of different china clay mine tasks was analyzed by video-photographic method. Different pulmonary function parameters, viz, FVC, FEV1, FER and PEF were measured by a digital spirometer to assess the severity of Chronic Obstructive Pulmonary Disease (COPD). Results: The results showed that the working pulse rate and CSI vary with different mine task. It was highest in subjects carrying china clay by head mode. The magnitude of CSI was found to vary with the change of work time and the rest time among the workers. Pulmonary function parameters of china clay mine workers were significantly lower (P<0.01) than other industrial workers. About 79% of total population was suffering from different grades of COPD. Among them, 12% were suffering from severe COPD and 60% from moderate COPD. The higher prevalence of COPD among china clay mine workers might be due to exposure of china clay dust in the work place. Conclusion: It was concluded that the china clay mine workers were suffering from high degree of physiological stress while performing different mine tasks.DOI: http://dx.doi.org/10.3126/ijosh.v2i2.6594 International Journal of Occupational Safety and Health, Vol 2.
