title = "The Association between a Minimum Amount of Physical Activity and Subsequent Muscle Strength and Balance in Older Adults: A Prospective Study",
abstract = "This study aimed to investigate the association between 15 min of daily moderate-to-vigorous physical activity (MVPA) and subsequent muscle strength and balance in older adults. Data concerning community-dwelling older Taiwanese adults (mean age, 69.5 years) were collected during the baseline period (2018) and at a 12-month follow-up survey (2019). Time spent performing MVPA was objectively assessed using a triaxial accelerometer (ActiGraph wGT3x-BT) at baseline. Upper and lower limb muscle strength were measured using handgrip strength and a five-times sit-to-stand test, respectively. Balance was assessed using a one-leg standing test. The 12-month variations in muscle strength and balance were calculated through subtracting follow-up data from baseline data. A forced entry-adjusted logistic regression analysis was conducted. In total, 65.2% of participants engaged in at least 15 min of daily MVPA in the baseline survey. After adjusting for confounders, older adults who achieved 15 min of daily MVPA during the baseline period were more likely to maintain or improve balance performance (odds ratio, 8.12). Performing 15 min of daily MVPA was found to benefit older adults{\textquoteright} subsequent balance performance but not muscle strength.",

note = "Funding Information: In total, 218 potential participants were randomly recruited using convenience sampling. Of these, 19 declined to attend the on-site examination and 29 did not meet the inclusion criteria for age (n = 24) and independent walking ability (n = 5). A total of 170 participants completed self-administered questionnaires, of whom, 148 completed an on-site examination and wore an accelerometer for seven days. After data cleaning, 127 participants provided complete data for analysis. After our follow-up estimation 12 months later, participants who could not be reached, who were unable to attend, or who were unwilling to attend were excluded (n = 38). Complete data concerning 89 participants were included in this study. No recommendation was given to the participants in terms of PA after baseline, and no PA was registered at follow-up. A flowchart of the participant recruitment process is shown in . Each participant provided written informed consent prior to study participation.
