Abstract

Background: Low level of physical activity can reduce physical fitness. Aerobic training can improve physical fitness. A precise aerobic training based on anaerobic threshold (AT) is recommended by American College of Sports Medicine (ACSM) whenever possible. Methods: This was a randomized-single blinded control trial including 24 male subjects with low level of physical activity in Kariadi hospital during December 2023 until February 2024. It was randomized with a sealed envelope. Subjects were allocated in 2 groups (above AT and below AT). Physical performance was measured using SPPB score and muscle endurance that was presented using total repetition of 1RM of knee flexor muscle. Results: There was no significant difference between two groups for total SPPB score (p=0.053). There was a significant difference of muscle endurance between two groups (p=0.010) with the above AT group resulting in higher improvements of muscle endurance (12.00 ± 5.71 vs. 6.67 ± 3.26). Conclusion: Aerobic exercise with intensity based on AT did not show significant differences in total SPPB score. However, aerobic exercise above AT showed a better improvement of muscle endurance in healthy adult men with low levels of physical activity.

Abstract

BACKGROUND: Coronavirus Disease 2019 (COVID-19) can lead to long-lasting complications such as ongoing respiratory issues and functional impairments. Damage to the alveoli and respiratory muscles, particularly the diaphragm, may result in lower maximal inspiratory pressure (MIP) and decreased physical performance. Although prior studies have examined the connection between MIP and functional tests in various respiratory conditions, research focusing on post-COVID-19 populations, particularly in Indonesia, is scarce. AIMS:  To investigate the correlation between Maximal Inspiratory Pressure (MIP) and 30-second Sit-to-Stand (30s STS) test performance in adult post-COVID-19 patients. METHOD: A cross-sectional study was conducted at two tertiary hospitals in Jakarta, Indonesia, involving 40 adults post-COVID-19 patients aged 18–59 years. Participants underwent clinical screening, spirometry, MIP measurement using the MicroRPM device, and the 30s STS test. Pearson correlation analysis was used for normally distributed variables with significance set at p < 0.05. RESULT:  The average MIP was 79.03 ± 26.68 cmH₂O, while the mean score for the 30s STS test was 12.78 ± 2.47 repetitions. Spirometric measurements revealed an average FEV₁ of 2.23 ± 0.57 L, FVC of 2.84 ± 0.69 L, and an FEV₁/FVC ratio of 81.19%. A moderate positive correlation between MIP and 30s STS performance was identified (r = 0.515, p = 0.001). CONCLUSION: There is a significant moderate correlation between MIP and 30s STS performance among post-COVID-19 patients, suggesting that simple functional tests can be effective tools for assessing respiratory muscle strength and informing rehabilitation strategies in clinical environments.
