“…But as per Brouha (1967) HR in the industry should not exceed 110 beats/min as cumulative fatigue would likely to ensue beyond this HR level. Later, Saha et al, (1979) proposed that the acceptable workload for sustained physical activity might be considered as 35% of the maximum aerobic power for Indian male workers, which corresponded to working heart rate of 110 beats/min. The mean average working HR was found to be 127.80 ±4.68 beats/min and 130.13 ± 4.21 beats/min in the YC and OC respectively.…”

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 (WBGT out ) 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.

“…According to Maritz [18] the working heart rate of 105 beats min -1 , with a range of 95 to115 beats min -1 would be accepted for 8 h industrial work shift. Brouha [7] re-stated that the working heart rate should not exceed 110 beats.min -1 otherwise there is a chance of cumulative fatigue.…”

“…Considering the severe muscular stress, shift in body axis, heart rate determining the acceptable load [20,21,22] it can be concluded from that the maximum acceptable load for the head mode should be around 15 kg and that for shoulder and waist mode should not be more than 10 kg at the speed of 3.5 km.hr -1 . It was also estimated in a study conducted on adult female construction workers and household workers that the MAWL is around 15 kg [23].…”
