“…This percentage of arterial Hb with oxygen is evaluated by measuring percutaneous arterial oxygen saturation (SpO 2 ), and SpO 2 indicates the oxygen level in the body. A lower SpO 2 occurs in acute mountain sickness, which can include various severe symptoms [6,7]. Therefore, to maintain oxygen levels, people who stay at high altitude and Andean highlanders have increased Hb concentrations or SpO 2 .…”

Background Many studies have reported specific adaptations to high altitude, but few studies have focused on physiological variations in high-altitude adaptation in Andean highlanders. This study aimed to investigate the relationships between SpO2 and related factors, including individual variations and sex differences, in Andean highlanders. Methods The participants were community-dwelling people in La Paz, Bolivia, aged 20 years and over (age range 20–34 years). A total of 50 men and 50 women participated in this study. Height, weight, SpO2, hemoglobin concentration, finger temperature, heart rate, and blood pressure were measured. Information about lifestyle was also obtained by interview. Results There were individual variations of SpO2 both in men (mean 89.9%, range 84.0–95.0%) and women (mean 91.0%, range 84.0–96.0%). On Student’s t test, men had significantly lower heart rate (p = 0.046) and SpO2 (p = 0.030) than women. On the other hand, men had significantly higher SBP (p < 0.001), hemoglobin (p < 0.001), and finger temperature (p = 0.004). In men, multiple stepwise regression analysis showed that a higher SpO2 was correlated with a lower heart rate (β = − 0.089, p = 0.007) and a higher finger temperature (β = 0.308, p = 0.030) (r2 for model = 0.18). In women, a higher SpO2 was significantly correlated with a higher finger temperature (β = 0.391, p = 0.015) (r2 for model = 0.12). A higher SpO2 was related to a higher finger temperature (β = 0.286, p = 0.014) and a lower heart rate (β = − 0.052, p = 0.029) in all participants (r2 for model = 0.21). Residual analysis showed that individual SpO2 values were randomly plotted. Conclusion Random plots of SpO2 on residual analysis indicated that these variations were random error, such as biological variation. A higher SpO2 was related to a lower heart rate and finger temperature in men, but a higher SpO2 was related to finger temperature in women. These results suggest that there are individual variations and sex differences in the hemodynamic responses of high-altitude adaptation in Andean highlanders.

“…Another factor implemented by the HCM was collecting of physiological data, especially SpO 2 , the amount of which increased with the personal use of convenient devices. The focus of pulse oximetry discussions was on the prediction of AMS 23,24) . We considered that measuring SpO 2 could help to prevent AMS because pulse oximetry reflects personal respiratory status at high altitude and thus encourages load reduction and more respiration.…”

The crew members of an endurance motor sports rally team developed acute high-altitude illness (AHAI) during the first year of a route that included driving at high altitude for three days. Therefore, a health care manager (HCM) was assigned to the team to help prevent AHAI during the second and third years. We evaluated the effect of the HCM on the prevalence of AHAI. Methods: The numbers of individuals who presented at the official medical tent of the rally were recorded. Reports from another team without an HCM served as the control. Results: The rates of visits were essentially the same between the two teams (5 [20.8%] of 24 vs. 3 [20.0%] of 15) respectively during 2016. These values were reduced in the team with the HCM during 2017 and 2018, but did not change in the control team (1 [4%] of 25 and 0 [0%] of 25, respectively vs. 3 [18.8%] of 16; P = 0.0128 Fisher exact test). Conclusions: An HCM with knowledge of AHAI was effective in preventing the development of AHAI among endurance rally crews.

“…An alteration in the athlete's arterial blood oxygenation (SpO 2 ) may explain decrements in performance (Siegler et al, 2007 ), especially at altitudes where this value is lowered, and may also help to predict acute mountain sickness (Basnyat, 2014 ).…”

Athletes adapt their training daily to optimize performance, as well as avoid fatigue, overtraining and other undesirable effects on their health. To optimize training load, each athlete must take his/her own personal objective and subjective characteristics into consideration and an increasing number of wearable technologies (wearables) provide convenient monitoring of various parameters. Accordingly, it is important to help athletes decide which parameters are of primary interest and which wearables can monitor these parameters most effectively. Here, we discuss the wearable technologies available for non-invasive monitoring of various parameters concerning an athlete's training and health. On the basis of these considerations, we suggest directions for future development. Furthermore, we propose that a combination of several wearables is most effective for accessing all relevant parameters, disturbing the athlete as little as possible, and optimizing performance and promoting health.
