Purpose
Reduced cardiovascular fitness post-stroke may negatively impact recovery. There is little information regarding exercise testing performance and cardiorespiratory response to an aerobic exercise intervention in subacute stroke. The purpose of this study was to examine cardiorespiratory response in subacute stroke after an 8-week aerobic exercise intervention using a total body recumbent stepper (TBRS).Methods
Nine individuals with mean age 61.2 (SD 4.7) years and mean 66.7 (SD 41.5) days post-stroke completed the exercise intervention. Participants had a mean Fugl-Meyer score of 100.3 (SD 29.3). Outcome measures were obtained at baseline and postintervention. A peak exercise test using a TBRS assessed oxygen consumption, heart rate, and minute ventilation. Participants completed an 8-week exercise intervention on a recumbent stepper 3 times per week at a prescribed heart rate intensity.Results
Submaximal VO2 was significantly lower from baseline to postintervention with a main effect of Study Visit (F1,8 = 8.5, p = 0.02). Heart rate was not significantly different pre- to postintervention. Minute ventilation exhibited no main effect of Study Visit or Test Minute.Conclusion
Moderate-high intensity aerobic exercise in subacute stroke appears to be beneficial for improving cardiovascular outcomes during submaximal performance of an exercise test.Key Words: oxygen uptake, cerebrovascular accident, cardiovascular fitness, submaximal exercise 相似文献2.

Purpose
To determine if 30 minutes of Nintendo Wii Sports boxing provides cardiorespiratory benefits and contributes to the daily exercise recommendations for healthy young adults.Methods
Twenty healthy 23- to 27-year-olds participated in two sessions to measure maximum heart rate (HRmax) via a treadmill test and heart rate (HR) response to 30 minutes of Wii Sports boxing. Heart rate in beats per minute (bpm) was measured continuously, and exercise intensity during each minute of play was stratified as a percentage of HRmax. Mixed designs analysis of variance (ANOVA) and Pearson product moment correlations were used to analyze the data.Results
Mean (SD) HR response to boxing was 143 (15) bpm or 77.5% (10.0%) of HRmax. The mean HR response for experienced participants was significantly lower than inexperienced participants, P = .007. The ANOVA revealed a significant interaction between experience and time spent at various intensities, P = .009. Experienced participants spent more time in light to vigorous intensities, inexperienced participants in moderate to very hard intensities. Fitness was not correlated with mean HR response to boxing, P = .49.Conclusion
Thirty minutes of Nintendo Wii Sports boxing provides a moderate to vigorous aerobic response in healthy young adults and can contribute to daily recommendations for physical activity.Key Words: exergaming, cardiorespiratory training, active video games 相似文献5.

Purpose
Large therapeutic rolls (LTR) and balls are popular rehabilitation tools and have also been advertised as cardiovascular training devices. The aim of this study was to determine if individuals of varying fitness levels would reach aerobic training levels by evidence-based standards as described in American College of Sports Medicine (ACSM) publications.Methods
Fourteen volunteers performed a maximal exercise test and on subsequent days, two submaximal exercise tests on the LTR (LTR-A and -B). LTR-A consisted of four 5-minute stages of exercise at progressive intensity levels. LTR-B included 20 minutes of continuous exercise. Oxygen consumption (VO2) and heart rate (HR) during exercise on the LTR were compared with ACSM recommended standards.Results
The average (range) peak intensity achieved during LTR-A was 66.8% (51.7-82.7%) of maximal VO2 reserve (VO2R) and 82.9% (70.7%-91.2%) of maximal heart rate (HRmax). During LTR-B, HR and VO2 of all participants was maintained at moderate exercise intensity and averaged 56% of VO2R and 78% of HRmax during the 20 minute exercise period.Conclusions
These findings suggest that individuals with a wide range of aerobic fitness are able to reach and maintain aerobic training levels with appropriate exercise on a large therapeutic roll or ball.Key Words: large therapeutic roll, Swiss Ball, aerobic exercise, exercise intensity 相似文献6.

Purpose
To determine the opinions and attitudes toward exercise in people with chronic obstructive pulmonary disease (COPD) who had completed a randomised controlled trial of 12-months maintenance exercise.Methods
Participants were eligible for recruitment to the maintenance exercise study if they had COPD and had completed an 8-week pulmonary rehabilitation program. They were randomized into an Intervention Group (IG) that consisted of once weekly, supervised hospital-based maintenance exercise plus home exercise for 12 months or a Control Group that undertook unsupervised home maintenance exercise for 12 months. At the end of the 12 months, participants completed a survey consisting of 23 questions using a visual analogue scale (VAS) of 100 mm.Results
Forty-eight participants completed the 12 month study and 36 participants (75%) completed the survey [IG mean (SD): age 65 (8) years, FEV1 58 (20) % predicted; CG: age 66 (8) years, FEV1 67 (17) % predicted]. No between group difference was found for the importance of exercise, the benefits of the program or the importance of support from the physiotherapist. However, the IG reported exercising more regularly, having more enjoyment of being involved in the maintenance exercise program, greater benefit in general well-being, and better physical fitness.Conclusions
At the completion of the 12 month exercise study, the survey results showed that all participants reported positive attitudes towards both supervised and unsupervised maintenance exercise programs, with the IG reporting greater benefits.Key Words: COPD, survey, maintenance exercise program 相似文献7.

Purpose
The purpose of this study was to compare an Exercise Training Group (EX) with an Attention-Control Group (AT-C) to more specifically assess the impact of exercise training on individuals with heart failure (HF).Methods
Forty-two individuals with HF were randomized to AT-C or EX that met with the same frequency and format of investigator interaction. Baseline, 12- and 24-week measurements of B-type naturetic peptide (BNP), 6-minute walk test (6-MWT), and the Kansas City Cardiomyopathy Questionnaire (KCCQ) were obtained.Results
BNP tended to increase in the AT-C while remaining stable in the EX over time. A clinically significant increase in 6-MWT was demonstrated by the EX but not the AT-C. The EX achieved a clinically significant change on the KCCQ at 12 weeks, with further improvement by 24 weeks, while the AT-C demonstrated a clinically significant change at 24 weeks.Conclusions
Attention alone was inadequate to positively impact BNP levels or 6-MWT distances, but did have a positive impact on quality of life after 24 weeks. Although exercise offers enhanced benefits, individuals with HF unable to participate in an exercise program may still gain quality of life benefits from participation in a peer-support group that discusses topics pertinent to HF.Key Words: heart failure, attention, exercise 相似文献8.

PURPOSE
The primary purpose of this study was to investigate 6-minute walk test (6MWT) performance in young children who were normal weight (NW) and overweight (OW).METHODS
Seventy children, 5-9 years of age, participated in this study. The 6MWT was performed on an indoor walkway. Heart rate (HR), blood pressure (BP), and oxygen saturation (SaO2) were measured. A self-reported physical activity questionnaire was completed by a parent/guardian. Data were analyzed with independent t tests, ANOVA, correlation analyses, and logistic regression.RESULTS
The systolic BP values were higher in the children who were OW compared with their NW peers (resting mean 104.1 (8.9) mmHg vs. 97.5 (7.8) mmHg, P < 0.05; post-6WMT: mean 118.4 (10.78) mmHg vs. 109.9 (9.1) mmHg, P < 0.05). The SaO2 values were lower in the children who were OW compared to their NW counterparts (resting: mean 97.2 (1.1) % vs. 98.0 (1.0) %, P < 0.05; post-6WMT: mean 96.8 (1.0) % vs. 97.7 (1.0) %, P < 0.05).CONCLUSIONS
The children who were OW had higher systolic BP and lower SaO2 levels at rest and post-6WMT. More research is needed to determine if these differences contribute to children who are OW having difficulty performing exercise.Key Words: obesity, children, exercise capacity 相似文献10.

Purpose
The purpose of this review is to evaluate the literature related to mobilization of the critically ill patient with an emphasis on functional outcomes and patient safety.Methods
We searched the electronic databases of PubMed, CINAHL, Medline (Ovid), and The Cochrane Library for a period spanning 2000–2011. Articles used in this review included randomized and nonrandomized clinical trials, prospective and retrospective analyses, and case series in peer-reviewed journals. Sackett''s Levels of Evidence were used to classify the current literature to evaluate the strength of the outcomes reported.Results
Fifteen studies met inclusion criteria and were reviewed. According to Sackett''s Levels of Evidence, 9 studies were level 4 evidence, one study was level 3, 4 studies were level 2, and one study was level one evidence. Ten studies pertained to patient safety/feasibility and 10 studies pertained to functional outcomes with 5 fitting into both categories.Conclusion
A search of the scientific literature revealed a limited number of studies that examined the mobilization of critically ill patients in the intensive care unit. However, literature that does exist supports early mobilization and physical therapy as a safe and effective intervention that can have a significant impact on functional outcomes.Key Words: mobilization, exercise, intensive care unit, critical illness, physical therapy 相似文献13.

Purpose
The study purpose was to assess perceptions of physical therapists (PTs) regarding the role of physical therapy in cardiovascular disease (CVD) prevention.Methods
A 25-item survey, validated by expert cardiovascular/pulmonary (CVP) PTs, was sent electronically to 2,673 PTs. Each item represented an element of clinical practice behavior: education of CVD/risk factors (EDCVD), administration of primary CVD prevention (PRECVD), identifying underlying CVD/risk factors (IDCVD), monitoring CV status in patients with CVD (MONCVD). Responses were assigned numeric values (strongly agree = 5 to strongly disagree = 1), and mean element scores were analyzed.Results
Most of the 516 respondents were APTA Section members (34% CVP Section, 42% other Section membership) and worked in academia (53%). Items showing a high (> 95%) level of agreement included patient education of smoking (97%) and monitoring exercise intensity (99%), assessing exercise benefits (99%), clinically identifying obesity (97%) and hypertension (97%), and monitoring CV response to exercise (99%). Items failing to reach 80% overall agreement were patient education of CVD medications (79%) and blood chemistry (72%), and assessing CVD family history (75%), patient BMI (60%), and body composition (33%). Identifying underlying CVD (77.2%) was the only practice behavior failing to reach 80% agreement. Outpatient PTs agreed significantly less to all elements vs. academics, and to IDCVD vs. all PTs except home health.Conclusions
Physical therapists support most CVD prevention behaviors, but not given elements of patient education and identifying underlying CVD/risk factors.Key Words: cardiovascular disease, primary disease prevention, secondary disease prevention 相似文献15.

Purpose
Recently there has been increased interest in early mobilization of critically ill patients. Proposed benefits include improvements in respiratory function, muscle wasting, intensive care unit (ICU), and hospital length of stay. We studied the frequency of early mobilization in our intensive care unit in order to identify barriers to early mobilization.Methods
A 4-week prospective audit of 106 patients admitted to a mixed medical-surgical tertiary ICU (mean age 60 ± 20 years, mean APACHE II score 14.7 ± 7.8) was performed. Outcome measures included number of patient days mobilized, type of mobilization, adverse events, and reasons for inability to mobilize.Results
Patients were mobilized on 176 (54%) of 327 patient days. Adverse events occurred in 2 of 176 mobilization episodes (1.1%). In 71 (47%) of the 151 patient days where mobilization did not occur, potentially avoidable factors were identified, including vascular access devices sited in the femoral region, timing of procedures and agitation or reduced level of consciousness.Conclusions
Critically ill patients can be safely mobilized for much of their ICU stay. Interventions that may allow more patients to mobilize include: changing the site of vascular catheters, careful scheduling of procedures, and improved sedation management.Key Words: intensive care units, mobility, physical therapy 相似文献18.

Purpose
The purpose of this review was to assess the quality of evidence on inspiratory muscle training (IMT) in patients with heart failure and to provide an overview on subject selection, training protocols, and outcome achieved with IMT.Methods
Literature search was first performed via the PubMed database, and additional references were identified from the Scopus citation index. Articles of the review type and of clinical trials published in English were included. Quality of the articles was assessed using Sackett''s levels of evidence and rigor of methodology was assessed using PEDro (Physiotherapy Evidence Database) criteria for randomized controlled trials and the Downs & Black tool for cohort studies.Results
Twelve articles of clinical trials were included. Typical training protocols involved daily training with intensity greater than 30% of maximal inspiratory pressure (PImax), duration of 20 to 30 minutes (continuous or incremental) and using a pressure threshold muscle trainer. The effect sizes of PImax, walk test distance, and dyspnea were moderate to large across these studies. Effects on quality of life scores were inconsistent.Conclusion
Inspiratory muscle training is beneficial for improving respiratory muscle strength, functional capacity, and dyspnea in patients with stable heart failure and respiratory muscle weakness.Key Words: inspiratory muscle training, heart failure, maximal inspiratory pressure 相似文献19.

Purpose
The purpose of the present pilot study was to provide a preliminary estimate of the minimum detectable difference (MDD) and minimum clinically important difference (MCID) of the six-minute walk test (6MWT) and daily activity in outpatients with chronic heart failure (CHF).Methods
A convenience sample of 22 adults with stable New York Heart Association Functional Class II and III CHF performed two baseline 6MWTs separated by 30 minutes of rest. Subjects then wore a triaxial accelerometer for 7 days to monitor daily activity. After 7 weeks of usual care, subjects again wore the accelerometer for 7 days and then returned to the clinic to complete the Global Rating of Change Scale (GRS) with regard to their heart disease and perform another set of 6MWTs. For the 6MWT, the MDD was calculated using the two baseline 6MWT distances. For daily activity, the MDD was calculated using two methods: (1) day-to-day test-retest reliability during baseline monitoring, and (2) baseline to follow-up test-retest reliability in those who reported no change on the GRS. The MCID for the 6MWT and daily activity was calculated using the mean and 95% confidence interval (CI95%) for those subjects who reported ‘improvement’ on the GRS.Results
The MDD at the CI95% for the 6MWT was 32.4 meters. The MCID for the 6MWT was 30.1 (CI95% 20.8, 39.4) meters. The MDD for daily activity was 5,909 vector magnitude units (VMU·hr.−1) The MCID for daily activity was 1,337 VMU·hr.−1 There was good alignment of the MDD and MCID for the 6MWT, suggesting that clinically meaningful change is approximately 32 meters. However, the calculated MCID was substantially less than measurement error as represented by the MDD, indicating that the MCID was underestimated in this sample or that daily activity may be robust to change in overall disease status.Key Words: six-minute walk test, daily activity, heart failure, clinically meaningful change 相似文献20.
