Key result
Cricketers show a lower resting heart rate of ~57 bpm versus others, with similar HRV.
Why the study?
Resting heart rate and heart rate variability at rest are important for evaluating training load, recovery, and adaptation in sports, prompting exploration of these parameters across different athletic groups.
Cross-Sectional (n=43)
p-value: p=< 0.05
Cricketers demonstrate a significantly lower resting heart rate compared to other athletes and non-athletes, without significant differences in heart rate variability.
No practice change for athlete evaluation; leaves open sport-specific autonomic effects for prospective study.
Resting heart rate (RHR) is a primary marker to understand the overall physical state of an individual. Rhythmic changes in heart rate (HR) at any given point reflect the complex interactions between parasympathetic and sympathetic nerves system. Assessment of workload through HR can be confusing unless RHR is known. RHR & heart rate variability (HRV) at rest are important to justify training load, recovery and adaptation in sports. The study was carried out to explore the values of RHR and HRV parameters of cricketers, athletes and non-athletes of West Bengal. Forty three male volunteers with a mean age of 20.2 ± 2.1 years were selected for the study. Five minutes R-R intervals were recorded during resting state in the supine position. Mean HR, SDNN, and rMSSD of cricketers has been found to be 57 ± 5 bpm, 54.5 ± 15.7 ms, and 66.8 ± 21.6 ms respectively. No significant difference found in SDNN and rMSSD of three groups but a significant (p < 0.05) difference has been observed in RHR of cricketers. A low resting heart rate, a kind of bradycardia, has been found in the cricketers.

Subhashis Biswas (2020) reported a cross-sectional. Athletic status (cricketers and athletes) vs. Non-athletes was evaluated on Resting heart rate (RHR) and heart rate variability (SDNN, rMSSD) (p=< 0.05). Cricketers exhibited a significantly lower resting heart rate (57 ± 5 bpm) compared to athletes and non-athletes (p < 0.05), with no significant differences in heart rate variability.
