“…It is well established that these elements are determinants of walking speed. (37,38) These results therefore are consensual, which is an argument for the consistency of our study and confirms the relevance of the association with vitamin D.…”

The purpose of this study was to determine whether there was an association between serum 25-hydroxyvitamin D [25(OH)D] concentration and walking speed measured at usual and fast pace among older women. Usual-and fast-pace walking speeds and 25(OH)D concentrations were assessed in 739 randomized older women (mean age 80.2 AE 3.5 years) from the EPIDOS study. The following 25(OH)D thresholds were used: 10, 20, and 30 ng/mL. Walking speed was dichotomized on being in the worst quintile or not. Age, body mass index, number of chronic diseases, physical activity, quadriceps strength, cognition, use of psychoactive drugs, and serum parathyroid hormone were used as potential confounders. The results show that 90% of subjects had 25(OH)D insufficiency. Only fast-pace walking speed was significantly different between groups ( p ¼ .

“…These findings confirm those of previous studies and indicate that when compared with young people, older people exhibit slower comfortable walking speed [5,9], reduced ability to quickly rise from a chair [3,10]. These age-related differences in functional mobility have been attributed to impaired sensorimotor function [11,12], in particular reduced lower extremity strength and power [13][14][15], but also increased fear of falling [8] and reduced aerobic capacity [16].

Aging induces decrease of locomotor capacity and its decrease is associated with an increased risk of falls. Several lines of evidence indicate that both change in muscle power and aerobic fitness are causative. Mobility tests are usually based on a maximal exercise stress test; however, this test is often difficult and sometimes frightening to older persons. Therefore, the objective of this study was to examine age and gender differences in 3-min walk distance test (3WDT), and time of chair-rising test (CRT) of functional mobility. 153 men and 159 women aged from 20 to 78 years were recruited as subjects of the present study. The body composition measured the height, body mass (BM), body mass index (BMI), lean tissue mass (LTM), and waist circumference (WC). The Functional mobility tests measured the peak oxygen uptake (V O2peak ), 3WDT, leg extension strength (LES), and times of CRT. Both in men and women, height and BMI, WC decreased and increased, respectively, with age. Height, BM, LTM, WC in men are higher than in women. We found no correlation between ages and 3WDT in women and a significant, negative correlation in men. All parameters of fitness performance were negatively correlated with age. Both in men and women, all parameters of fitness performance were positively correlated with sex. Both in men and women, V O2peak , 3WDT, and LES decreased with age. All parameters of fitness performance in men are higher than in women. Both in men and women were observed for the correlation between 3WDT and V O2peak , LES and CRT respectively. Although as the correlation coefficient between 3WTD and V O2peak , LES and CRT were low (r = 0.28 -0.38), an error may occur, this study shows that 3WDT and CRT test can be a feasible method of providing the information for muscle power and aerobic fitness, possibly avoiding the need for a maximal stress test.

Purpose: To evaluate the effects of prehabilitation (enhancing physical capacity before total hip or knee joint arthroplasty) on pain and physical function of adults with severe hip and knee osteoarthritis (OA). Methods: Consecutive patients (n ¼ 650) from 2006 to 2008 with hip or knee OA awaiting total joint arthroplasty (TJA) attended a hospital outpatient clinic for a prehabilitation assessment. All participants completed self-report (Lower Extremity Functional Scale [LEFS] and visual analogue scale for pain [VAS]) and functional performance measures (self-paced walk [SPW], timed stair, and timed up-and-go [TUG] tests). A subset of 28 participants with severe disability participated in a structured outpatient prehabilitation programme. Between-group differences were assessed via independent t-tests; paired Student's t-tests and Wilcoxon signed rank tests were used to compare changes in pain and function following the prehabilitation programme. Results: A total of 28 individuals (16 female) with mean age 67 (SD 10) years and BMI 33 (8) kg /m 2 awaiting TJA (10 hips, 18 knees) participated in a prehabilitation programme of 9 (6) weeks' duration. Relative to baseline, there was significant improvement in LEFS score (mean change 7.6; 95% CI, 1.7-13.5; p ¼ 0.013), SPW (mean change 0.17 m/s; 95% CI, 0.07-0.26; p ¼ 0.001), TUG (mean change 4.2 s; 95% CI, 2.0-6.4; p < 0.001), and stair test performance (mean change 3.8 s [SD 14.6]; p ¼ 0.005) following prehabilitation. Conclusion: This study presents preliminary evidence that prehabilitation improves physical function even in the most severely compromised patients with OA awaiting TJA.Key Words: arthroplasty; exercise; osteoarthritis; physical therapy specialty; rehabilitation.
