In brick making industry, brick carrying activity requires extreme physical efforts and imposes additional load on cardiovascular system of the workers in hot environment. Lack of data about age associated alteration of cardiac cost among the brick carriers impinged us for this study. The purpose of this study was to assess the cardiac cost of two age groups of brick carriers in summer seasons. 156 brick carriers, having minimum one years experiences, were divided into two groups i.e., younger carriers and older carriers. Anthropometric parameters along with different cardiac indices were calculated with Polar Heart-Rate Monitor. The wet bulb globe temperature (WBGTout) index of the worksite was also measured. Group-wise comparison of cardiac indices and effect of age on those indices were performed using t - test and correlation coefficients respectively adjusting for confounders. All cardiac parameters were positively correlated with one another except for average working HR with PREC, Relative CC and Net CC; Working HR max with PREC and Relative CC; and SRHB with Relative CC. It was seen that the brick carriers surpassed the recommended limits of cardiac strain indices like Net CC and Relative CC, especially with increasing age. This indicates the job used to heavy to extremely heavy in accordance with the cardiac parameters.
