  • The Effect of Ice on Shoulder Proprioception in Badminton Athletes
    Publication . Marouvo, Joel; Tavares, Nuno; Dias, Gonçalo Nuno Figueiredo; Castro, Maria António
    This study aims to analyze the influence of the application of cryotherapy on shoulder proprioception in badminton athletes. Thirty federated badminton athletes were included in this study, all of whom belonged to three of the teams currently competing in national competitions (Portugal). Their mean ages were 21.00 ± 5.60 years, and their experience in the modality was 8.40 ± 6.93 years. They practiced in an average of 2.93 ± 1.26 training sessions per week. All of them used their right hand to hold the racket. Each participant’s dominant shoulder joint position and force senses were evaluated for four consecutive time points through the isokinetic dynamometer Biodex System 3. The experimental procedure consisted of applying ice for 15 min and the control procedure consisted of no therapeutic intervention. The proprioception outcomes were expressed using the absolute error, relative error, and variable error. All statistical analysis was performed using PASW Statistics 18 software (IBM-SPSS Statistics). There were no statistically significant changes in the joint position and force senses after the intervention, as well as during the subsequent 30 min. We conclude that, after this cryotherapy technique, there is no increased risk of injury associated with a proprioception deficit that prevents athletes from immediately returning to badminton practice.

    Introduction: Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. This disease harmed people's lives, compromising a healthy lifestyle. Objective: This study aims to analyze the impact of COVID-19 lockdown on the Portuguese population's physical activity and seated time during quarantine. Methodology: This retrospective longitudinal study was based on an online Google Forms survey concerning the lockdown period from 18th March to 30th April, 2020. A total of 541 responses were analyzed; all Portuguese (42.2 ± 14.8 years) completed the survey concerning the period. The valid responses were obtained from the 4th to 30th of May 2020. The physical activity during a week and the average seated time on a weekday before (T0) and during (T1) the quarantine were studied. Results: When comparing T0 and T1, there was a decrease in moderate-vigorous physical activity (p < 0.0001), walking time (p < 0.0001), and an increase in seated time (p < 0.0001), considering the whole sample group. All age groups decreased the time spent walking and increased the time seated. The highest value of seated time was displayed in the age interval of 26–35. Compared to the others, the age interval of 46—55 years showed the lowest values for vigorous and moderate activity. Conclusion: The first quarantine had a significantly negative effect on the Portuguese population's physical activity hours and contributed to a significant increase in the seating time during a weekday.
