Comparison Among Heart Rate, Perceived Exertion, and Blood Lactate Concentration for 2 Different Submaximal Exercise...

The purpose of the study was to determine the relationship between heart rate, rate of perceived exertion, and blood lactate concentration in recreational cricket players between the modified Bruce protocol and the continuous backward medicine ball throw (CBMB) test. The goal was to develop an alternate, inexpensive test for submaximal exercise testing.

Thirteen recreational cricket players were recruited from Jamia Millia Islamia, New Delhi. The heart rate and rate of perceived exertion were recorded at rest during standing, at the time of reaching the ventilatory threshold, and after 1, 2 and 3 minutes of the recovery period during the modified Bruce protocol and continuous backward medicine ball throw test. The blood lactate levels were recorded at rest while standing, at the time of reaching VT, and after 3 minutes of the recovery period during the modified Bruce protocol and the continuous backward medicine ball throw (CBMB) test, and also at the end of stage 1 for modified Bruce protocol and at the end of 10 reps for continuous backward medicine ball throw test.

The mean age of the recreational cricket player in the study was 22.23±1.87 years. Significant 'r' values were found for heart rate (r=.975, p<.001), and blood lactate concentration (r=.824, p=.001) between the modified Bruce protocol and the continuous backward medicine ball throw test.

The continuous backward medicine ball throw (CBMB) test for submaximal exercise testing showed validity when compared to the Bruce protocol in recreational cricket players.
