Background: Heart Rate Variability (HRV) in soccer training provides important indicators for coaches to evaluate and monitor training. High-Intensity Interval Training (HIIT) and Short-Game Sprints (SSG) have also been used and tested for athletes to enhance soccer performance. For this reason, this experimental study aimed to compare the effects of SSGs and HIIT on Heart Rate (HR) key indicators for continuous and targeted monitoring of training sessions of soccer players. Methods: Twenty-four male U-15 soccer players were divided into two groups with 12 people. The duration of both training protocols was 20 minutes. daily Heart Rates(d.HR), Resting Heart Rate (RHR), Maximum Heart Rate (MHR), Training zone Heart Rates (Tz.HR), were observed and recorded using a Polar team HR monitor app. TRIMP was calculated using the Edwards training load method that determines the internal load by measuring the product of the accumulated training duration of five HR zones by a coefficient related to each zone. The results were considered significant at the 95% confidence level (p ≤ 0.05). Results: HIIT and SSG showed no significant difference in MHR, HR reserve, HR mean, HRmax and TRIMP-Edwards of pre and post-test. Among SSG group, recorded a significant improvement in RHR (P=0/001) also, among HIIT group recorded significantly improved RHR (P=0/001). The HR mean for each training session, the HR mean in five minutes, and The HR mean in the associated training zones were monitored and recorded. Conclusion: In general, the results of this research showed that the HRV and other HR indicators in the training program are important for monitoring training by soccer coaches, and that through these indicators, the goals of progress in training will be achieved.
