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

Area of Science:

• Sports Science
• Exercise Physiology
• Biomedical Engineering

Background:

• Submaximal exercise testing is crucial for assessing cardiovascular fitness.
• The Bruce protocol is a standard but resource-intensive method.
• Developing cost-effective alternatives is essential for wider accessibility.

Purpose of the Study:

• To evaluate the relationship between heart rate, perceived exertion, and blood lactate in cricket players.
• To validate the continuous backward medicine ball throw (CBMB) test as an alternative to the modified Bruce protocol for submaximal exercise assessment.

Main Methods:

• Recruited 13 recreational cricket players.
• Measured heart rate, rate of perceived exertion, and blood lactate during modified Bruce and CBMB tests.
• Recorded data at rest, ventilatory threshold, and during recovery.

Main Results:

• Found significant correlations between the two tests for heart rate (r=.975, p<.001) and blood lactate (r=.824, p=.001).
• Demonstrated strong agreement in physiological responses between the protocols.

Conclusions:

• The continuous backward medicine ball throw (CBMB) test is a valid and cost-effective alternative for submaximal exercise testing in recreational cricket players.
• CBMB test offers a practical option for assessing fitness in this population.
