Are the Timed Up and Go Test and Functional Reach Test useful predictors of temporal-spatial gait parameters in older persons?
Journal Title: Human Movement - Year 2016, Vol 17, Issue 3
Abstract
Purpose. The aim of the study was to analyze relationships between the results of commonly used functional fitness tests for older persons, the Times Up and Go (TUG) test and Functional Reach Test (FRT), and temporal-spatial gait parameters determined with the GAITRite system. Methods. The study included 60 healthy, physically active older persons with mean age of 70.4 ± 5.1 years. Functional fitness of the study subjects was evaluated with the TUG test and FRT, and their temporal-spatial parameters were determined with the GAITRite system. Results. Results of the TUG test correlated inversely with step length (r= -0.70 and r= -0.61 for preferred and fast speed, respectively), stride length (r= -0.71 and r= -0.61, respectively) and velocity (r= -0.69 and r= -0.38, respectively). Regression model with these explanatory variables explained 43% of variance in the TUG test results (p≤0.0001). Results of FRT correlated positively with step length (r=0.61 and r=0.54, for preferred and fast speed, respectively), stride length (r=0.60 and r=0.56, respectively) and velocity (r=0.37 and r=0.38), and regression model with these variables explained 26% of variance in the FRT outcome. Conclusions. Basic temporal-spatial parameters of gait at a preferred speed, i.e. velocity, step length, stance time, single support time, swing time and double support time, explain up to 43% of variance in the TUG test outcome and 26% of variance in the FRT results.

The relationship between 500 m and 2000 m simulated rowing times for schoolboy rowers over a training period of three years
Purpose. Available data finds that for schoolboy rowers the 2000 m on-water or laboratory rowing distance causes fatigue and depresses their ability to train during the following days. Thus, looking for a less demanding...
