Introduction: The one-minute sit-to-stand test (1min-STST) is a practical assessment tool for measuring functional ability. Reference values are currently unavailable for populations residing at high altitudes. Aims: To establish reference values for the 1min-STST in people living at high altitudes by sex and age range. Additionally, we correlate the variables analyzed with the number of repetitions obtained in the tests. Methods: Multicenter cross-sectional research was conducted, collecting data from two cities at high altitudes. Healthy adults between 18 and 80 years old were recruited. Anthropometric measurements, physical activity levels, smoking habits, and the number of repetitions during the 1min-STST were recorded. A multiple linear regression was performed to determine the predictive equations by sex. The stepwise method was used to generate the predictive model. Results: As many as 400 healthy subjects (58% women) were included. Participants had a median (P25-P75) height of 1.62 (1.56-1.68) cm, a weight of 63.0 (57.8-70.1) kg, and a BMI of 24.2 (22.5-26.0) kg/m2. The predictive equations were: 1minSTSTMen=19.833 - (age* 0.168) + (height * 0.204) - (weight * 0.122); 1minSTSTWomen= 27.845 - (age * 0.198) + (height * 0.145) - (weight* 0.094). Conclusion: The reference values for 1min-STST were determined for the healthy population aged 18-80 years living at high altitudes.

Background: Several studies have shown that pulmonary telerehabilitation (PTR) improves respiratory capacity. However, there is little evidence of its effectiveness in youth with post-COVID-19 conditions (PCC). This study analyzed the effects of a PTR program on young adults with PCC. Methods: Sixteen youths were randomly assigned to a control group (CG) or an experimental group (EG), with eight participants each. The EG participated in a PTR program that included twelve remote, asynchronous four-week sessions with diaphragmatic breathing and aerobic exercises. Vital signs (SpO2, HR, RR, BP), physical capacity (sit-to-stand test), cardiorespiratory capacity (6-Minute Walk Test), and perceived exertion (Borg scale) were assessed in both groups. Results: Statistical analyses showed a significant decrease in RR and HR (p < 0.012) and an increase in SpO2 (p < 0.042), physical (p < 0.012), and respiratory (p < 0.028) capacity. Perceived effort decreased significantly in both groups (CG: p < 0.006; EG: p < 0.001) only for physical but not for cardiorespiratory capacity (p < 0.106). There were no statistical changes registered in BP (p > 0.05). Conclusions: The PTR program, which includes respiratory and aerobic exercises, is feasible and effective in improving physical and cardiorespiratory capacity in young people with PCC, as well as reducing HR, RR, and dyspnea.

Web-based pulmonary telehabilitation: a systematic review

Web-based pulmonary telerehabilitation (WBPTR) can serve as a valuable tool when access to conventional care is limited. This review assesses a series of studies that explore pulmonary telerehabilitation programmes delivered via web-based platforms. The studies involved participants with moderate to severe chronic obstructive pulmonary disease (COPD). Of the 3190 participants, 1697 engaged in WBPTR platforms, while the remaining 1493 comprised the control groups. Sixteen studies were included in the meta-analysis. Web-based pulmonary telerehabilitation led to an increase in daily step count (MD 446.66, 95% CI 96.47 to 796.86), though this did not meet the minimum clinically important difference. Additionally, WBPTR did not yield significant improvements in the six-minute walking test (MD 5.01, 95% CI − 5.19 to 15.21), health-related quality of life as measured by the St. George’s Respiratory Questionnaire (MD − 0.15, 95% CI − 2.24 to 1.95), or the Chronic Respiratory Disease Questionnaire (MD 0.17, 95% CI − 0.13 to 0.46). Moreover, there was no significant improvement in dyspnoea-related health status, as assessed by the Chronic Respiratory Disease Questionnaire (MD − 0.01, 95% CI − 0.29 to 0.27) or the modified Medical Research Council Dyspnoea Scale (MD − 0.14, 95% CI − 0.43 to 0.14). Based on these findings, this review concludes that WBPTR does not offer substantial advantages over traditional care. While slight improvements in exercise performance were observed, no meaningful enhancements were noted in dyspnoea or quality of life metrics. Overall, WBPTR remains a complementary and accessible option for managing and monitoring COPD patients. However, further research and innovation are required to improve its efficacy and adapt it to various clinical environments.
