Résumé:
Purpose: This study aimed to examine the differences in heart rate variability (HRV) between athlete and non-athlete students in middle school using unimplemented sensor heart rate. Materials and Methods: Sixty-seven judo athlete and non-judo-athlete students were recruited to the study from middle school were divided into experimental groups (n = 39, height 162.4 ± 7.6 cm, weight 52.7 ± 6.3 kg, Age 12.8 ± 1.3 years), and Control group student (n = 37, height 159.1 ± 6.9 cm, weight 53.2 ± 7.3 kg, age 13.2 ± 0.8 years),The CG students did not take part in any competitive sport at any level, Measure mean heart rate (Mean HR), mean R-R, standard deviation of all normal R-R intervals; (SDNN) and relative, root of the mean squared differences of successive RR intervals (RMSSD),low-frequency (LF), high-frequency (HF) and low-frequency ratio (LF/HF) indicators were used. The T-tests was used to compare sports teams with general differences between athlete and non-judo-athlete students. The significance level was set at p < .05. Results: HRV analysis software analyses the (RR) interval time domain components and the results were given as standard deviation of RR intervals (SDNN), square root of the mean of the sum of the squares of differences between adjacent RR intervals (RMSSD), adjacent RR interval differing more than 50ms (NN50), The Mean (iRR) of the EG is significantly higher than that of the average CG (t = 2.245, p < .05); in terms of Mean HR, the EG are significantly lower than the average CG (t = -2.149, p < .05). Conclusion: Judo training and combat field exercises utilising connected sensors are effective for middle-aged individuals, helping to maintain and reduce resting heart rate while enhancing cardiopulmonary function.
