Inactivity during COVID-19 Quarantine and its Effects in Strength and Functional Parameters in Elderly: A Case-Study

Abstract

Background: Coronavirus 2019 (COVID-19) may be defined as a disease with pandemic characteristics. Although social distance may be able to combat the spreading of the virus, negative repercussions in general population ́s health may occur, especially in older people. Then, the aim of the present case-study was to assess the effects of a 6 month-detraining period in strength and functional parameters of a previously strength-trained elderly woman. Methods: Lower limbs maximal strength (one maximum repetition test [1RM]), timed-up and go (TUG) and Sit to Stand (STS) tests were performed pre and post the inactivity period. Results: Relevant reductions in 1RM (-25.9%) and in the number of repetitions performed in STS (-28.5%) were observed. In addition, the performance in TUG (+30.5%) was also impaired after the detraining phase. Conclusion: In conclusion, physical inactivity during the COVID-19 quarantine induced important reductions in strength and functional parameters in the elderly participant. Then, it can be recommendable that older people initiate or maintain their RT practices even at home during this period in order to maintain optimal general health and quality of life.

Also, the participant was free from any muscle or skeletal injury and negatively responded all the questions in the PAR-Q. Before initiating the study, the participant was informed about all the details and procedures adopted during the study, read and signed a consent form. In addition, the voluntary was also familiarized with the testing procedures. The study followed all the norms of the Brazilian National Health Council (CNS), according to the 510/2016 resolution.
