Abstract:
To determine the concurrent validity and responsiveness of the 6 minute walk test (6-MWT) as a measure of cardiorespiratory fitness in people with fibromyalgia.Subjects completed the 6-MWT, a Fibromyalgia Impact Questionnaire (FIQ), and a peak oxygen consumption (pVO2) exercise test before (n = 28) and after (n = 20) a 12 week exercise program.The correlations between 6-MWT distance and pVO2 before (r = 0.328) and after (r = 0.420) the exercise program were not significant. Significant correlations were obtained between 6-MWT distance and FIQ total (r = -0.494, p < 0.01) and physical impairment (r = -0.403, p < 0.05) scores. Fifteen of 28 subjects completed the exercise program, with significant (p < 0.05) changes in 6-MWT distance (+78 m), pVO2 (+1.8 ml/kg/min), and FIQ total score (-9.9). The change in 6-MWT distance was correlated significantly (p < 0.05) with change in FIQ total score but no change in pVO2.The 6-MWT was not a valid predictor of cardiorespiratory fitness. However, it was sensitive to change and was also significantly related to FIQ total score.Keywords:

Fibromyalgia is a chronic widespread unexplained musculoskeletal pain syndrome with decreased pain threshold. Because the etiology of fibromyalgia is unknown and the pathogenesis is unidentified, treatment is largely symptomatic and not standardised. The pain and fatigue reported by individuals with fibromyalgia results in a relative sedentary lifestyle, hence also a decrease in the fitness level of skeletal muscles.In order to assess the effect of exercise in fibromyalgia, the Cochrane Controlled Trials Register was reviewed; 17 studies of exercise interventions on cardiorespiratory endurance, muscle strength and/or flexibility were selected.The results from the studies are inconsistent but low-intensity aerobic exercise regimens were found to be one of the few effective treatments. In these studies, however, subjective pain levels fail to show significant improvement, although improvements are seen on other parameters such as improvement in the number of tender points, in total myalgic scores and reduced tender point tenderness, improved aerobic capacity, physical function, subjective well-being and self-efficacy.The group exercises varied from 1-3 times per week, sessions from 25 minutes to 90 minutes; the duration of the programmes from 6 weeks to 6 month. Most of the programmes were low-intensity dynamic endurance training with a working rate at 50-70 % of maximal heart rate in relation to age.

Introduction: VO2 max is the maximum oxygen amount of that can be consumed during intense physical activity until eventually fatigue occurs. A person with a good level of VO2 max means having good physical fitness as well. Physical fitness gives the ability to a person to do daily productive work in the absence of excessive fatigue. The low one cardiorespiratory fitness may incrase the risk of death from heart disease and hypertension. Giving freeletic exercise is one of the techniques used to improve cardiorespiratory fitness or VO2 max. Methods: This research is Pre-experimental research with one group pre-post test design. The sample of the study amounted to 20 people and freeletic exercise was given 12 times. The measuring tool used is Multistage Test of Fitness / Beep Test to know the level VO2 max of sample before and after freeletic sporting practice. Results: The results of this study indicate that 17 respondents experienced a significant increase in VO2 max and 3 other respondents did not experience improvement by giving 12 times freeletic sports exercise. Conclusion: Based on Paired T test to know whether or not there is influence, it can be concluded that there is influence of giving freeletic sport to max VO2 level on freeletic community member after given 12 times (p< 0,001, p<0,05) freeletic sport practice.

This review presents and addresses the conflicting results on cardiorespiratory fitness among adults with fibromyalgia. The heterogeneity in study designs, symptom severity and the assessment protocols might partly explain these conflicting results. It also presents the possible relationship between cardiorespiratory fitness and exercise prescription, attrition from exercise/rehabilitation programmes and independence with activities of daily living. Cardiorespiratory fitness might impact aerobic exercise and independence in daily activities of patients with fibromyalgia, which is often concomitantly diagnosed in patients with sleep disordered breathing, including patients with obstructive sleep apnoea. Therefore, cardiorespiratory fitness evaluation should be considered by general and respiratory physicians as well as physiotherapists who treat patients diagnosed with fibromyalgia for more accurate diagnosis, exercise prescription and monitoring of patients’ status. Key points Adults with fibromyalgia often present with reduced cardiorespiratory fitness. Reduced cardiorespiratory fitness might have an important impact on functional capacity and quality of life. Adults with fibromyalgia who have a secondary condition affecting their ventilatory anaerobic threshold and/or V ′ O 2 peak , for example chronic obstructive pulmonary disease, might present with a greater reduction of their cardiorespiratory fitness which may not be entirely related to their lung disease. Educational aims To better understand the cardiorespiratory fitness results among adults with fibromyalgia in general, and when taking into account differences in assessment protocol (maximal versus submaximal testing protocol; cycle ergometer versus treadmill testing protocol) and symptom severity (fibromyalgia severity level). To better understand how cardiorespiratory fitness among adults with fibromyalgia could: 1) assist in exercise prescription; 2) minimise dropout rates from exercise/rehabilitation programmes; and 3) promote independence with activities of daily living. To learn why fibromyalgia might be important to consider in adults who have concurrent fibromyalgia and lung disease.

To compare 2 exercise modalities, aerobic fitness training and stretching exercises, in patients with fibromyalgia (FM) in relation to function, pain, quality of life, depression, and anxiety, and to correlate the cardiorespiratory fitness gain with symptom improvement.Seventy-six women with FM between 18 and 60 years old were randomized to either an aerobic program or stretching program, for 20 weeks. They were evaluated at the beginning of the program and after 10 and 20 weeks in relation to the improvement of aerobic fitness, flexibility, function, Fibromyalgia Impact Questionnaire (FIQ), Short-form Health Survey (SF-36), and depression and anxiety levels. Ventilatory anaerobic threshold (VT) and maximum oxygen uptake (VO2max) were determined by expired gas analyses.Aerobic exercise was superior to stretching in relation to VO2 max, VT, function, depression, pain, and the emotional aspects and mental health domains of SF-36. Patients in the stretching group showed no improvement in depression, "role emotional," and "mental health." No association was noted between improvement in aerobic fitness as measured by VT and the improvement of pain, function, or scores in FIQ and SF-36.Our results confirm that aerobic exercise is beneficial to patients with FM, but the cardiorespiratory fitness gain is not related to improvement of FM symptoms.

Objective: The aim of this study was to evaluate the cardiorespiratory fitness and perceived exertion of female patients with fibromyalgia syndrome (FMS) compared with that of healthy female subjects. Design and Subjects: This was designed as a cross-sectional case-control study, with a consecutive sample of 30 female patients with FMS and an age-matched control group of 67 healthy female subjects. Setting: This study was conducted at the multidisciplinary pain center of a university hospital in a city of more than 1 million inhabitants. Outcome Measures: A cardiorespiratory fitness index (PWC65%/kg) and an original perceived exertion index (B65%) were obtained from the heart rates and perceived exertions scored on a 10-point Borg scale during a submaximal cycle ergometer test. Average indexes for the FMS patients and control subjects were compared. Results: The mean cardiorespiratory fitness index of the FMS patients was not significantly different from that of the controls. The mean perceived exertion index in the FMS patients was significantly greater than that of the controls, meaning that the FMS patients systematically reported higher ratings of perceived exertion during exercise. Conclusions: Cardiorespiratory fitness, as expressed by a submaximal work capacity index, seems normal in female patients with FMS compared with age- and sex-matched healthy individuals. The fact that FMS patients overscore their perception of exertion may be due to a greater overlap of peripheral pain and perceived exertion perceptions during exercise. This observation should be noted when using perceived exertion scores to prescribe and monitor exercise in FMS patients.

There are evidences that physical exercise is an effective instrument for improving physical fitness, health, and quality of life and causes beneficial effects on the symptoms of patients with fibromyalgia. The purpose of this study was to analyze effects of a functional training program on pain, fitness, and quality of life in patients with fibromyalgia in a 9-year prospective longitudinal cohort study. Forty women with fibromyalgia participated in this study; 24 received an exercise program and were called the active group; and 16 were the control group. Tender points, visual analogical scale (VAS) of pain, physical fitness, Fibromyalgia Impact Questionnaire (FIQ), and Short-Form Health Survey 36 (SF-36) were analyzed. The active group experienced significant improvements in FIQ, TP, and VAS (P < .001), whereas the control group showed significant worsening in the FIQ scale (P = .004). Moreover, the active group experienced significant improvements in leg strength (P < .001), balance (P = .033), cardiorespiratory fitness (P < .001), emotional role (P = .024), and mental health (P = .025); whereas the control group significantly worsened on handgrip strength (P = .017), balance (P = .043), cardiorespiratory fitness (P = .020), and in general health (P < .001). A Pearson correlation analysis revealed a significant relationship between the improvement in physical fitness variables and the improvements in FIQ, TP, and VAS. In conclusion, a regular practice of moderate-intensity physical activity shows a positive effect long-term on fitness, pain, the impact of the disease, and the quality of life in women with fibromyalgia.

Abstract The purpose of this study was to examine the effects of a 6-month cycling aerobic exercise intervention on cardiorespiratory fitness and the dose-response relationship in community-dwelling older adults with mild-to-moderate Alzheimerʼs dementia. The FIT-AD trial was a single blind, 2-parallel group, pilot randomized controlled trial. The aerobic exercise group participated in a 6-month, thrice weekly, moderate-vigorous intensity cycling intervention while control group performed stretching. Cardiorespiratory fitness was evaluated by peak oxygen consumption from cardiopulmonary exercise test and peak walking distance from the shuttle walk test and 6-minute walk test. Aerobic exercise dose was calculated using the novel heart rate physical activity score. The aerobic exercise group significantly increased peak oxygen consumption (1.28 ml/kg/min; p=0.03) in subgroup who achieved maximal criteria on cardiopulmonary exercise test. Changes in peak oxygen consumption and peak walking distance on the shuttle walk and 6-minute walk tests did not significantly differ between aerobic exercise and stretching groups. Notably, the aerobic exercise dose was strongly and significantly correlated to change in peak oxygen consumption (r=0.60; n=16; p=0.01), in subset who met maximal test criteria. Emphasis on exercise dose is needed in aerobic exercise programs to maximize cardiorespiratory fitness gains in persons with mild-moderate Alzheimerʼs dementia.

Fibromyalgia (FM) is a chronic syndrome characterized by widespread musculoskeletal pain that causes a significant reduction in functional capacity, affecting thus health and quality of life (QOL).The aim of the present study was to evaluate the performance of FM patients in the 6-Minute Walk Test (6MWT) and its relation with health and QOL.Thirty-six FM patients (all women), differentiated by degree of severity of disease, and 14 healthy women were evaluated. Distance walked in the 6MWT, cardiorespiratory responses, heart rate responses, kinematic parameters of gait, the results of the Fibromyalgia Impact Questionnaire (FIQ), and the results of the Short-Form Healthy Survey (SF-36) were analyzed.Women with FM covered a shorter distance in the 6MWT, had a lower cardiorespiratory response, and had lower spatio-temporal parameters of gait than healthy women. No correlation was found in FM patients between the total FIQ score and the distance walked in the 6MWT.The analysis of performance parameters in the 6MWT may be an element of clinical relevance in FM patients.
