Background: Proprioception is important for stability of body segments, postural control, and functionality. However, there are no studies in literature showing effects of online Pilates exercises that create proprioceptive inputs on vertebra on trunk proprioception., Aims: This study aims to reveal effect of online Pilates exercises conducted on trunk proprioception and core muscle endurance in healthy individuals., Methods: We included thirty-three healthy individuals between ages of 18 and 25 in study. Individuals were randomly divided into two groups. There were 17 individuals in Pilates group (PG), and 16 individuals in control group (CG). The PG was given online Pilates exercises by the physiotherapist in groups 3 days a week for 6 weeks, 1 h a day. There was no exercise program recommended for individuals in CG. We evaluated trunk proprioception with an inclinometer, core muscle endurance with three core endurance tests created by McGill, and prone bridge tests. All evaluations completed just before start of study and 2 days after 6-week training., Results: Two groups had similar demographic characteristics, and there was no difference between baseline measurements (p > 0.05). While improvement observed in PG in trunk proprioception and all of core muscle endurance tests (p < 0.05), no statistically significant difference reported in CG (p > 0.05)., Conclusions: We revealed that online Pilates exercises performed at mat level for 6 weeks in healthy individuals had positive effects on trunk proprioception and core muscle endurance with this study. Contribution of Pilates exercises to development of both muscular endurance and proprioceptive senses, even if performed at a distance, is important., (© 2021.

Background: Symptoms related to Coronavirus-19 disease (COVID-19) and quarantine measures have caused pulmonary function abnormality and impaired respiratory mechanics. However, no studies are evaluating pulmonary functions and respiratory muscle strength in female volleyball players according to COVID-19 status in the pandemic., Aims: This study aims to compare pulmonary functions and respiratory muscle strength in female players with and without COVID-19., Methods: Seventeen players (23.47 ± 5.89 years) who were recovered from COVID-19 and 25 female volleyball players (20.48 ± 5.05 years) who were not infected by SARS-CoV-2 were included in the study. Maximal inspiratory and expiratory pressure, pulmonary functions, body composition, symptom severity, and perceptions of performance were evaluated., Results: Measured and predicted percent maximal inspiratory pressure and measured maximal expiratory pressure values of COVID-19 players were statistically significantly lower than non-COVID-19 players (p < 0.05). Dynamic lung volumes were similar in groups (p > 0.05)., Conclusions: Inspiratory and expiratory muscle strength in COVID-19 players were more affected compared with non-COVID-19 players. Pulmonary functions were mostly preserved in COVID-19 players. Respiratory muscle weakening can affect the performance of female players. Therefore, respiratory muscle strength training could be suggested in female players with COVID-19 to increase respiratory muscle strength and prevent deterioration in performance.
