An additional 17 healthy control participants were recruited. Cardiorespiratory fitness (CRF) was measured using oxygen consumption (VO_2peak), and additional measures of walking speed (m s^-1), leg strength and body composition were also assessed. Differences between groups were assessed by matched pairs t-tests. Effect sizes were calculated using Cohen's d. Results: There were no significant differences in age, BMI, muscle mass or body fat between groups (p > 0.05). Peak VO₂ was lower in the stroke group for the shuttle walk test (p = 0.037) and progressive cycle test (p = 0.019), as were all CRF test performance measures (p < 0.05). Stroke survivors walked significantly (p < 0.001) slower at both self-selected and fast speeds. Effect sizes of group differences for all leg strength variables were medium to large, with peak torque lower in the stroke group for all trials. Conclusions: Despite being independently ambulant and community dwelling, the CRF, walking speed and leg strength of this group were reduced compared to non-stroke comparison participants. These patients may benefit from undertaking targeted exercise programmes.]]> Wed 19 Jan 2022 15:16:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31501 2 ) was recorded continuously using a portable metabolic system. The average VO₂ during each 30-second epoch was determined. VO₂ ≥10.5 mL/kg/min was categorised as ≥moderate intensity. Findings: Participants exercised at VO₂ ≥10.5 mL/kg/min for the majority of the time on the workstations [functional: 369/472 epochs (78%), ergometer: 170/204 epochs (83%)]. Most (69%) participants exercised for ≥30 minutes. No serious adverse events occurred. Conclusions: Applying interval training principles to a circuit of functional and ergometer workstations enabled ambulant participants to exercise at an intensity and for a duration that can improve cardiorespiratory fitness. The training approach appears feasible, safe and a promising way to incorporate both cardiorespiratory fitness and functional training into post-stroke management.]]> Wed 19 Jan 2022 15:16:20 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33277 2peak) was evaluated using a portable metabolic system during the 6-minute walk test (6MWT), the Shuttle Walk Test (SWT) and the cycle graded exercise test (cGXT). Walking speed, balance, body composition, fatigue, depression and HRQoL were also measured. Results: CRF improved significantly from pre-intervention to 12-month follow-up on the 6MWT (Effect Size, ES = 0.87; p = 0.002) and cGXT (ES = 0.60; p<0.001), with more modest improvements on the SWT (ES = 0.52; p = 0.251). From baseline to 12 months, significant within-participant improvements were found for self-selected walking speed, balance and HRQoL. Performances on the remaining tests were maintained over the post-intervention period. Conclusion: There may be health benefits of providing people with stroke an exercise intervention with long-term support that encourages increased regular physical activity.]]> Wed 10 Nov 2021 15:12:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47793 Tue 31 Jan 2023 15:05:01 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42384 2peak) and heart rate (HR_peak) were recorded. There were no differences (p > 0.05) in mean VO_2peak among the three tests (min-max: 17.08–18.09 mL kg⁻¹ min^−1,). For individuals, small discrepancies in VO_2peak between the 6MWT and other tests were greater with higher fitness levels. HRpeak was significantly (p = 0.005) lower during the 6MWT. Correlations between VO_2peak and performance measures within each test were high (6MWT VO_2peak and distance: r = 0.78, SWT VO_2peak and shuttles: r = 0.73, cycle GXT VO_2peak and workload: r = 0.77) suggesting the performance measures may be clinically useful as proxy measures of CRF. Common comorbidities, such as lower-limb joint pain and poor balance, and participant’s fastest walking speed, should inform the choice of CRF test.]]> Tue 23 Aug 2022 11:15:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9581 Sat 24 Mar 2018 08:39:12 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10667 Sat 24 Mar 2018 08:12:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19897 2peak) assessed preintervention and postintervention via a progressive aerobic exercise test. Results: From 3209 citations identified, 28 studies were included, reporting results for 920 participants. Studies typically included chronic, ambulant participants with mild to moderate deficits; used an aerobic or mixed (with an aerobic component) intervention; and prescribed 3 sessions per week for 30 to 60 minutes per session at a given intensity. Baseline VO_2peak values were low (8-23 mL/kg/min). Meta-analysis of the 12 randomized controlled trials demonstrated overall improvements in VO_2peak of 2.27 (95% confidence interval = 1.58, 2.95) mL/kg/min postintervention. A similar 10% to 15% improvement occurred with both aerobic and mixed interventions and in shorter (≤3 months) and longer (>3 months) length programs. Only 1 study calculated total dose received and only 1 included long-term follow-up. Conclusions: The results demonstrate that interventions with an aerobic component can improve cardiorespiratory fitness poststroke. Further investigation is required to determine effectiveness in those with greater impairment and comorbidities, optimal timing and dose of intervention, whether improvements can be maintained in the longer term, and whether improved fitness results in better function and reduced risk of subsequent cardiovascular events.]]> Sat 24 Mar 2018 08:03:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52271 Mon 09 Oct 2023 10:04:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38018 Fri 23 Jul 2021 15:47:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54843 Fri 15 Mar 2024 15:08:40 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49426 Fri 12 May 2023 15:16:21 AEST ]]>
