Resting HR, i.e., HR before the first and second match in TT (resting HR1 TT, resting HR2 TT) and before the step test in XC skiers, is shown in **Figure 1** and **Table 2**. As shown in **Figure 2**, the difference in resting HR between TT players and XC skiers competing at 1 km and 3 km race is slight. Only in the case of XC skiers competing in 50 m race, resting HR was noticeably lower than the other athletes. In

The difference between the resting HR and HR after a 2-minute exercise was the most distinctive in XC skiers competing in 50 m race, for both men (23.6 beats per

When comparing HR after 2 minutes of exercise, the values are similar for all sport groups. An interesting finding for HR after 2 minutes of exercise was observed in male TT players whose HR after 2 minutes of exercise differed noticeably between the first and second analyzed match, the difference consisted of 26 beats per minute. In female TT players, no difference in the HR after 2 minutes of exercise was observed between the matches. Additionally, in TT a significant difference between female and male players in HR after 2 minutes of exercise was observed, whereas XC skiers had HR very similar in both men and women depending on the distance they specialized. The values and differences are shown in

The data collection was provided by the Healthy Athletes Clinical Directors and trained volunteers. All participants were in the spectrum of moderate levels of intellectual disability (below 70 points of IQ ) and practiced the sports for at least 1 year as according to the Special Olympics rules participants of the national SO games have to pass minimum 1 year training before the competition. Their characteristics are shown in **Table 1**. The informed consent with Healthy Athletes noninvasive screenings is provided by athletes and their caregivers prior the sport events. The athletes with ID liked to participate in Healthy Athletes screening as the HR mea-
