Background: Older adults with Alzheimer’s disease (AD) may be unable to perform treadmill testing due to balance issues. We investigated whether older adults with AD could successfully complete a peak cycle ergometer test. Methods: Peak oxygen consumption (peak [Formula: see text]) assessed via a cycle ergometer test in 44 participants with AD (age 78.4 ± 6.8). Physical function was assessed via the incremental shuttle walk, 6-minute walk, and the Short Physical Performance Battery (SPPB). Results: All participants completed the cycle ergometer test successfully. Peak [Formula: see text] was correlated with SPPB ( r = .35, P = .023), shuttle walk ( r = .35, P = .024), 6-minute walk ( r = .31, P = .05), and inversely with age ( r = −.4, P = .009). There was no correlation between peak [Formula: see text] and cognition. Conclusion: Older adults with AD are able to safely complete a peak cycle ergometer exercise testing protocol. We provide an individualized cycle ergometer test for determining aerobic capacity in older adults with AD who may be unable to perform treadmill testing due to balance or gait issues.

Dual Task Performance

Abstract Impairments in dual-task performance can be observed in healthy older adults when motor and cognitive assignments are applied simultaneously. According to the hypofrontality hypothesis, there may be a reduction in frontal cognitive function during exercise. Objective: The aim of the present study was to compare the performance changes on cognitive tests of depressive elderly (n=10), healthy older adults (n=10), and healthy young individuals (n=10) during cycle ergometer exercise. Methods: The groups were submitted to a working memory test, a short memory test and a semantic memory test, before and during a 20-minute cycle ergometer exercise at 80% of their age-predicted maximal heart rate. Results: Significant differences (p=0.04) were observed in scores on the digit backward test during exercise when young individuals were compared to healthy older adults. This result indicates that young subjects, as expected, had better performance than elderly. No significant differences were found among the groups for the digit forward subtest (p=0.40) or the vocabulary test (p=0.69). Conclusion: Data from this study showed that healthy older adults had impaired performance on higher cognitive tasks when these assignments were applied together with motor tasks.

Aim. The article deals with comparing the data obtained from exercise load tests by using various ergometers. Materials and methods. Twenty professional athletes (15 triathletes and 5 ski-racers) aged 14–38 participated in the test performed with the help of the cycle ergometer, treadmill, and Thorax Trainer ski machine. The experiment took place at the premises of UrFU sports research laboratory (Yekaterinburg, Russia). Cycle ergometer and treadmill tests were conducted with a maximal RAMP protocol and a system for exercise testing (Schiller). A high-intensity interval test was conducted with the help of Thorax Trainer ski machine. All tests were performed with the analysis of gas exchange and heart rate. Results. It was established that there were no significant differences in the reaction of the cardiorespiratory system to load when comparing the data from cycle ergometer and treadmill tests as well as cycle ergometer and ski machine tests. In particular, we found no significant differences in the values of maximum oxygen consumption, ventilation, maximum HR, HR at aerobic and anaerobic thresholds, and HR during recovery after the test. Conclusion. Cycle ergometer test with a maximal RAMP protocol is the most informative and universal method for the aerobic testing of functional capacity in professional athletes
