“…In addition, according to the predictive equation of the MIP and MEP values of the participants should be 67.6 and 76.2 cm H 2 O, respectively. So, the participants presented 22% lower values of MIP and 19% lower values of MEP, compared to the predictive values of the equation of Souto-Miranda et al 20 These findings have also been reported in other observational studies with post-COVID-19 patients 21 . Handgrip strength showed inverse moderate correlations with the 30-day mortality, length of hospital stay, and length of ICU stay.…”

OBJECTIVE: Patients with severe coronavirus disease 2019 develop high muscle weakness. The objective of this study was to analyze the physical fitness of post-COVID-19 patients and its relationship with dyspnea and health-related quality of life (HrQoL). METHODS: This observational, retrospective, cross-sectional study was conducted between October and November 2021 in the Universidad Europea de Madrid (Spain), with 32 post-COVID-19 patients aged 63.2 (14.1) years. Muscle strength, aerobic capacity, maximal respiratory mouth pressures, dyspnea, and HrQoL were analyzed 6-12 months after discharge for COVID-19. To analyze the relationship between continuous variables, Spearman's correlation test and Pearson's correlation test were performed. RESULTS: The participants had a mean handgrip strength of 22.1 (9.0) kg and very poor HrQoL. Negative moderate correlations were found between handgrip strength and length of hospital and intensive care unit stay (r=−0.37; p=0.002). In addition, muscle strength was negatively correlated with dyspnea (r=−0.37; p=0.008) and HrQoL, and moderate-large negative correlations were found between dyspnea and HrQoL. CONCLUSION: Higher handgrip strength was associated with lower COVID-19 severity and less sequelae. Therefore, either the patients with severe COVID-19 suffered greater muscle breakdown, or higher muscle strength acted as a mitigating factor for the disease. It is suggested that post-COVID-19 rehabilitation programs should focus on increasing muscle strength. Also, adequate physical fitness could mitigate the physical and mental post-COVID-19 sequelae.

“…As it was not the case, it may be that the COVID-19 infection caused an impairment in the strength of the inspiratory muscles. Nevertheless, in a recent systematic review about predictive MIP and MEP mouth equations, they conclude that there is high heterogeneity in these equations, and none is reliable enough 20 .…”

BACKGROUND:The infection caused by coronavirus disease 2019 can lead to respiratory sequelae in individuals who have experienced severe or mild symptoms. METHODS: An observational, cross-sectional study was developed, following the STROBE guidelines. Maximal inspiratory and expiratory mouth pressures were assessed in 50 healthy young students (26 women, 24 men; age 22.20±2.41 years). The inclusion criteria were as follows: aged between 18 and 35 years; control group: not diagnosed with coronavirus disease 2019; and coronavirus disease 2019 group: diagnosed with coronavirus disease 2019, at least 6 months ago. The exclusion criteria were as follows: obese/overweight; infected with coronavirus disease 2019 or coronavirus disease 2019 symptoms in the last 6 months; smokers; and asthmatics. RESULTS: When comparing with groups, the coronavirus disease 2019 group presented statistically significant lower maximal inspiratory pressure values compared with the control group (88.32±16.62 vs. 101.01±17.42 cm H 2 O; p=0.01). Regarding the maximal expiratory pressure, no significant differences were found. Similar results were found when performing a subgroup analysis by sex and group. CONCLUSIONS: Young students who suffered from coronavirus disease 2019 asymptomatically or mildly at least 6 months ago presented a significant decrease in the inspiratory muscle strength as a sequel, so we believe that patients affected by this disease should have a brief postinfection assessment of this musculature to detect the indication for cardiorespiratory rehabilitation.

“… 13 Therefore, the evaluation of respiratory muscle strength is clinically important and must be accurately measured and interpreted. 14 15 When providing respiratory training to patients whose respiratory muscles have weakened due to acute or chronic diseases, treatment should be initiated according to the patient's ability. This means that each country must have a normal level of respiratory muscle strength to set its final training goal.…”

Background In Korea, tests for evaluating respiratory muscle strength are based on other countries’ clinical experience or standards, which can lead to subjective evaluations. When evaluating respiratory function based on the standards of other countries, several variables, such as the race and cultures of different countries, make it difficult to apply these standards. The purpose of this study was to propose objective respiratory muscle strength standards and predicted values for healthy Korean adults based on age, height, weight, and muscle strength, by measuring maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and peak cough flow (PCF). Methods This cross-sectional study analyzed MIP, MEP, and PCF in 360 people, each group comprising 30 adult men and women aged 20–70, diagnosed as healthy after undergoing medical check-ups at a general hospital. Hand grip strength (HGS) and the five times sit-to-stand test (FTSST) results were also recorded. Correlations among respiratory muscle strength, participant demographics, and overall muscle strength were evaluated using Pearson’s correlation analysis. The predicted values of respiratory muscle strength were calculated using multiple regression analysis. Results Respiratory muscle strength differed from the values reported in studies from other countries. In the entire samples, both MIP and MEP had the highest correlations with peak HGS ( r = 0.643, r = 0.693; P < 0.05), while PCF had the highest correlation with forced expiratory volume in 1 s ( r = 0.753; P < 0.05). Age, body mass index, peak HGS, and FTSST results were independent variables affecting respiratory muscle strength. A predictive equation for respiratory muscle strength was developed using the multiple regression equation developed in this study. Conclusion Respiratory muscle strength index may differ by country. For more accurate diagnoses, standard values for each country are required. This study presents reference values for Korea, and a formula for estimation is proposed when no respiratory muscle strength measurement equipment is available.
