Abstract
The availability of stand-up exercise tests for the detection of AT (anaerobic threshold) in hemiplegic patients were discussed from following four standpoints.
1) Fourty-seven hemiplegic patients participated in stand-up exercise tests to detect AT. Each subject was ordered to stand up at the frequency of 20 times per minute from height-changeable seat controlled by oil pressure mechanism. The intensity of the work load was increased by lowering the seat height 5cm per min. At the peak work load, the mean HR was 86.0% of age-predicted maximal HR and the mean oxygen consumption was 77.5% of predicted maximal oxygen consumption. These values seemed to be sufficient to detect their AT.
AT of 44 subjects could be determined by arising point of VE/VO2 and AT of 42, by V-slope method. The mean AT was 52.4% of predicted maximal oxygen consumption, and the value seemed to be reasonable.
2) Two sets of stand-up exercise tests were conducted for 10 subjects to evaluate the reproducibility of this method. The statistically significant correlation was indicated between two ATs.
3) AT values were detected by both the stand-up and bicycle ergometer method in 11 hemiplegics. The statistically significant correlation was indicated between them.
4) AT of ambulant subjects was found to be significantly higher than that of non-ambulant ones. It seemed that the stand-up method was more practical for hemiplegic patients than any other ordinary ones because of its easiness in determining AT which suggested their physical fitness.
