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.]]> Sat 24 Mar 2018 08:44:07 AEDT ]]> Characteristics of exercise training interventions to improve cardiorespiratory fitness after stroke: a systematic review with meta-analysis 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 VO2peak values were low (8-23 mL/kg/min). Meta-analysis of the 12 randomized controlled trials demonstrated overall improvements in VO2peak 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 ]]> A home- and community-based physical activity program can improve the cardiorespiratory fitness and walking capacity of stroke survivors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29962 Sat 24 Mar 2018 07:30:59 AEDT ]]> Exercise capacity is not decreased in children who have undergone lung resection early in life for congenital thoracic malformations compared to healthy age-matched children https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33278 2max) and heart rate were measured. Prior to and immediately post CPET, lung function measures including Nitrogen Multiple Breath Washout (MBW) and spirometry were performed. Results: There were no significant between group differences in pre CPET lung function (P > 0.05) or maximal exercise capacity (VO2max CPAM: 39.4mL·kg-1·min-1, Control: 40.5mL·kg-1·min-1). Post CPET, FEV₁ was significantly lower in the CPAM group, with two participants diagnosed subsequently with exercise induced bronchospasm based on post-CPET spirometry and follow-up clinical investigations. Conclusion: Early life lung resection for CPAM does not appear to have negative implications for exercise capacity later in childhood. Clinicians should be aware that dyspnoea following exercise may be due to asthma rather than residual effects of CPAM in these children.]]> Mon 24 Sep 2018 15:53:24 AEST ]]> Independently ambulant, community-dwelling stroke survivors have reduced cardiorespiratory fitness, mobility and knee strength compared to an age- and gendermatched cohort https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33280 -1. An additional 17 healthy control participants were recruited. Cardiorespiratory fitness (CRF) was measured using oxygen consumption (VO2peak), 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.]]> Mon 24 Sep 2018 15:53:22 AEST ]]> Cardiorespiratory fitness and walking endurance improvements after 12 months of an individualised home and community-based exercise programme for people after stroke 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.]]> Mon 24 Sep 2018 15:53:19 AEST ]]> AExaCTT - Aerobic Exercise and Consecutive Task-specific Training for the upper limb after stroke: protocol for a randomised controlled pilot study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30579 max) immediately prior to the 1 hour of task-specific training with the therapist. Recruitment, adherence, retention, participant acceptability, and adverse events will be recorded. Clinical outcome measures will be performed pre-randomisation at baseline, at completion of the training program, and at 1 and 6 months follow-up. Primary clinical outcome measures will be the Action Research Arm Test (ARAT) and the Wolf Motor Function Test (WMFT). If aerobic exercise prior to task-specific training is acceptable, and a future phase 3 randomised controlled trial seems feasible, it should be pursued to determine the efficacy of this combined intervention for people after stroke.]]> Fri 24 Aug 2018 09:07:00 AEST ]]>
