“…However, the OG covered a greater distance during the tread6MWT compared to the CPX, which may be attributed to the self-selection of walking speed and lower physical requirements. Regarding the submaximal test, several studies have demonstrated shorter 6MWT distances covered by obese individuals, with an increase in distances after weight loss and/or aerobic training 6,12 .…”

“…However, given the increasing recognition of the value of functional capacity assessments in numerous populations in conjunction with acknowledgement of the difficulty in broadly applying CPX, there is a need for valid and reliable exercise testing assessments that can be implemented in a time-and costefficient manner 3 . The six-minute walking test (6MWT) is a well-established functional assessment 4 that may provide a reasonable estimation of functional capacity in obese patients 5,6 , even with associated diseases 7 . However, more work is needed in this area to validate initial findings.…”

years were included. Fourteen were allocated to the obese group and 15 to the eutrophic group. Anthropometric measurements and body composition assessment were performed. Results: In both tests, obese women presented with significantly higher absolute oxygen uptake, minute ventilation, and systolic and diastolic blood pressure; they also presented with lower speed, distance walked, and oxygen uptake corrected by the weight compared to eutrophics. During the maximal exercise test, perceived dyspnea was greater and the respiratory exchange ratio was lower in obese subjects compared to eutrophics. During the submaximal test, carbon dioxide production, tidal volume, and heart rate were higher in obese subjects compared to eutrophic women. When analyzing possible correlations between the CPX and the tread6MWT at peak, there was a strong correlation for the variable heart rate and a moderate correlation for the variable oxygen uptake. The heart rate obtained in the submaximal test was able to predict the one obtained in the maximal test. Bland-Altman plots demonstrated the agreement between both tests to identify metabolic and physiological parameters at peak exercise. Conclusions:The six-minute walking test induced ventilatory, metabolic, and cardiovascular responses in agreement with the maximal testing. Thus, the six-minute walking test proves to be important for functional evaluation in the physical therapy routine.Keywords: obesity; exercise test; physical fitness; physical therapy. ResumoContextualização: A reduzida tolerância ao exercício está relacionada à diminuída capacidade funcional consequente da obesidade.Objetivos: Analisar e comparar respostas cardiopulmonares, metabólicas e subjetivas durante um teste de esforço cardiopulmonar e um teste de caminhada de seis minutos na esteira em mulheres obesas e eutróficas. Métodos: Foram incluídas 29 mulheres com idades entre 20 e 45 anos. Catorze voluntárias foram alocadas no grupo de obesas e 15, no grupo de eutróficas. Foram realizadas medidas antropométricas e de composição corporal. Resultados: Em ambos os testes, as obesas apresentaram maiores valores de consumo absoluto de oxigênio, ventilação-minuto e pressão arterial sistólica e diastólica; ainda apresentaram menor velocidade de caminhada, distância percorrida e consumo de oxigênio relativo, quando comparadas com as eutróficas. Durante o teste máximo de exercício, a dispneia percebida foi maior e o quociente respiratório menor nas obesas em relação às eutróficas. Durante o teste submáximo, produção de dióxido de carbono, volume corrente e frequência cardíaca foram maiores nas obesas, comparadas às eutróficas. Houve forte correlação entre a frequência cardíaca e moderada correlação entre o consumo de oxigênio no pico dos testes. A frequência cardíaca obtida no teste submáximo aplicado foi capaz de predizer a frequência cardíaca obtida no teste máximo. IntroductionObesity-induced limitations of the cardiopulmonary and metabolic systems, commonly resulting in exertional dyspnea, collectively contribute to th...

Abstract:Introduction: Obesity is associated with a sedentary life style, which has a negative impact on physical fitness.Aim: To investigate physical fitness, physical activity level and time spent sitting in Swedish women before and one year after laparoscopic Roux-en-Y Gastric Bypass surgery (LRYGB).Method: Thirty-seven women (age: 41.2±9.6 years and Body Mass Index (BMI): 42±6.5 kg/m 2 ) were tested before and one year after LRYGB. (BMI: 30.5±5.8 kg/m 2 ). Physical fitness was assessed using the six minute walk test (6MWT), and three muscular endurance and one handgrip test. Physical activity level and sitting time were assessed using the short form of the International Physical Activity Questionnaire (IPAQ).Results: One year after surgery the mean distance walked during 6MWT increased from 532 m to 599 m (p=<0.001) and the muscular endurance was significantly improved (p 0.016), while no statistical significant difference was found in grip force compared to pre-operatively. After surgery, the women walked significantly more minutes/week (p=0.018) and increased their level of moderate (p=0.039) and vigorous (p=0.033) physical activity, but there were no significant differences in sitting time (p=0.206) compared to preoperatively. Conclusions:The physical activity level as well as physical fitness increased while grip strength remained same in Swedish women one year after LRYGB, compared to before surgery. The improved physical fitness and the considerable weight loss are important factors in reducing the risk of developing lifestyle associated diseases and risk of premature death in this group of women. But even if both physical activity and physical fitness increased at group level one year after LRYGB, some individuals still needed to be more physically active and to enhance the physical fitness level. These patients might benefit from physiotherapy to be able to be more physically active.

“…So far, the 6MWT has been used mainly in patients with chronic heart failure and pulmonary diseases to evaluate prognosis and treatment efficacy (16)(17)(18)(19). Few studies have been performed in obese subjects (20)(21)(22). Studies in obese children, adolescents, and adults show a high degree of reproducibility, indicating that the test is suitable for obese individuals as a group (23,24).…”

Obejctive: Weight loss and physical activity have shown favorable effects on risks associated with obesity. It is therefore of interest to evaluate exercise capacity and related co-morbidities in obese patients. Design and Methods: We present data from obese subjects evaluated by the 6-minute walk test (6MWT) before and after a 7.3 (6.1-8.2) month weight reduction program. Results: 251 subjects completed the test at baseline .6] kg/m 2 ) and 129 (51.4%) repeated the test after intervention .5] kg/m 2 ). The six minute walking distance (6MWD) at baseline (535 [480-580] m) and at follow up (599 [522-640] m) correlated to several cardiovascular risk markers. Age, weight, height, resting heart rate, smoking status, fP-glucose and use of b-blockers explained 43 % of the variance in predicted 6MWD at baseline. The effect of smoking status, fP-glucose, b-blockers, and resting heart rate lost significance at follow up. Presence of diabetes and the metabolic syndrome had a negative influence on 6MWD but did not affect the impact of intervention based on percentage increase in walking distance. Gender had no impact on 6MWD. Reported pain during the test was common but decreased after intervention (57.0% vs. 28.7%, P < 0.001). Conclusions: The 6MWT may be used to evaluate intervention success beyond kilogram weight loss in obese subjects. We present formulas to predict 6MWD and the effect of weight loss on walking distance in clinical practice. Pain is a common problem which has to be considered when giving advice on exercise as a part of weight loss intervention.
