Physical inactivity is a global problem which is related to many chronic health disorders. Physical activity scales which allow cross-cultural comparisons have been developed. The goal was to assess ...the reliability and validity of a Turkish version of the International Physical Activity Questionnaire (IPAQ). 1,097 university students (721 women, 376 men; ages 18–32) volunteered. Short and long forms of the IPAQ gave good agreement and comparable 1-wk. test-retest reliabilities. Caltrac accelerometer data were compared with IPAQ scores in 80 participants with good agreement for short and long forms. Turkish versions of the IPAQ short and long forms are reliable and valid in assessment of physical activity.
Purpose
This study aimed to evaluate respiratory muscle strength and endurance, maximal oxygen consumption, and fatigue of colorectal cancer (CRC) survivors and compare them with healthy individuals.
...Methods
Demographic and clinical characteristics were recorded. Respiratory muscle strength (maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP)) was measured using an electronic mouth pressure device, and respiratory muscle endurance was assessed using a constant workload protocol with linear workload device. Peak oxygen consumption (VO
2
peak) was measured using the cardiopulmonary exercise test (CPET) with modified Bruce protocol. Fatigue was assessed using the Brief Fatigue Inventory (BFI).
Results
The patients had similar demographic characteristics (
p
> 0.05). MEP (cmH
2
O and %predicted) were lower in the CRC group than in healthy controls (
p
< 0.05). MIP (cmH
2
O and %predicted) and test duration did not differ between the groups (
p
> 0.05). VO
2
peak (ml/min and %predicted) and VO
2
peak/kg (%predicted) were significantly lower in the CRC group (
p
< 0.05). BFI score differed significantly in the CRC and control groups (
p
< 0.05).
Conclusion
Respiratory muscle strength, maximal exercise capacity, and fatigue are adversely affected in CRC survivors. Cancer treatment may cause loss of muscle strength and impair energy metabolism and oxygen transmission. These changes can result in decreased exercise capacity and respiratory muscle strength and increased fatigue. Studies examining the effects of different exercise training programs in CRC survivors are needed.
Functional changes are essential determinants of mortality and morbidity in individuals with chronic liver disease. However, there is limited information about whether these changes persist long-term ...after liver transplantation (LT). We aimed to compare physical fitness, physical activity, balance, kinesiophobia, and fatigue between patients with LT and healthy controls. All participants underwent evaluation with the Senior Fitness Test (SFT) for exercise capacity and physical fitness, the International Physical Activity Questionnaire (IPAQ) for physical activity, the Timed Up-and-Go Test (TUG) and the Berg Balance Scale (BBS) for balance, the Tampa Scale for Kinesiophobia (TSK) for kinesiophobia, and the Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) for fatigue. We studied 16 persons with LT (M age = 40.56, SD = 15.73 years; M time since LT = 66.81, SD = 72.05 months) and 16 control participants (M age = 39.87, SD = 13.98 years). Compared to controls, participants with LT showed significantly poorer performance on the SFT components assessing upper and lower body strength, aerobic endurance, agility, and dynamic balance (p < .001 for all), significantly lower IPAQ physical activity scores (p = .002) and BBS score (p = .017), and significantly higher TUG time (p < .001) and TSK, FSS, and FIS scores (p = .001, p = .001, and p = .004, respectively). Individuals with post-LT had lower exercise capacity, physical fitness, balance, and physical activity, and higher kinesiophobia and fatigue levels in the long-term compared to their peers. Future studies should focus on frailty in individuals in the long term after LT.
PURPOSE:The purpose of this study was to investigate the effects of inspiratory muscle training (IMT) on functional capacity, respiratory muscle strength, pulmonary function, quality of life, and ...fatigue and dyspnea perception in patients with pulmonary arterial hypertension (PAH).
METHODS:Twenty-nine clinically stable PAH patients were included in this study. These patients were randomly assigned to a 6-week IMT program (14 patients) or to a sham IMT protocol (15 patients). Before and after the treatment, pulmonary function, respiratory muscle strength, functional capacity, dyspnea and fatigue perception, and quality of life were evaluated.
RESULTS:There were significant increases in maximal inspiratory and expiratory pressure, forced expiratory volume in 1 second (% predicted) and 6-minute walk distance in the IMT group compared with the control group (P < .05). There were significant decreases in the Fatigue Severity Scale score, Modified Medical Research Council dyspnea scores, and Nottingham Health Profile emotional reactions subscale in the IMT group compared with the control group (P < .05).
CONCLUSIONS:Inspiratory muscle training promotes significant improvements in respiratory muscle strength and functional capacity, thus resulting in a reduction of dyspnea during activities of daily living and less fatigue in PAH patients. Inspiratory muscle training is a clinically practical treatment for PAH without any complications.
Background
Primary ciliary dyskinesia (PCD) is a rare, hereditary, autosomal recessive disorder characterized by recurrent upper and lower respiratory tract infections. This study aimed to compare ...pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and activities of daily living (ADLs) retrospectively between patients with PCD and healthy controls.
Methods
Data from 20 patients with PCD and 20 matched, healthy counterparts recorded between July 2015 and January 2017 were analyzed. The data evaluated and recorded included pulmonary function using a portable spirometer, respiratory muscle strength (using a mouth pressure device, exercise capacity using the incremental shuttle walk test,), physical fitness (using the Munich Fitness Test), and ADLs (using the Glittre ADL test).
Results
Pulmonary function, respiratory muscle strength, incremental shuttle walk test scores (all parameters), and total Munich Fitness Test scores were lower in the PCD group relative to controls (P < 0.05). The duration to complete the Glittre ADL test was higher in PCD patients than in healthy subjects (P < 0.05).
Conclusions
Pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and ADL were affected by PCD. Thus, pulmonary rehabilitation regimens should be tailored according to these impacts.
Purpose This study investigated functional capacity, physical activity, and respiratory and peripheral muscle strength in different functional classes of pulmonary arterial hypertension (PAH) ...compared with healthy subjects. Subjects and Methods This study included 31 patients with class II (n = 16) or class III (n = 15) PAH, classified according to the World Health Organization. Fifteen healthy subjects served as controls. Functional capacity was assessed using the 6-minute walk test (6MWT). Physical activity was determined using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Respiratory muscle strength was measured using a mouth pressure device. Peripheral muscle strength was evaluated using a dynamometer. Results The 3 groups had similar demographic variables (p > 0.05). There were significant differences in 6MWT distance, maximal inspiratory pressure, and IPAQ categorical classification between the 3 groups (p < 0.05). Maximal expiratory pressure; total IPAQ score; and knee extensor, shoulder abductor, and hand grip strength were significantly lower in PAH patients (classes II and III) than in healthy subjects (p < 0.05). Conclusion As PAH progresses, respiratory muscle strength, functional exercise capacity, and physical activity decrease. Functional class should be taken into consideration when planning rehabilitation programs for this patient group.
For generations, cigarette smoking has presented an important public health concern. This study aimed to compare the health-promoting behavior, exercise capacity, physical activity level, health ...literacy, and knowledge level of smoking-related diseases between smokers and non-smokers.
The study included 71 smokers (mean age, 32.69±8.55 years) and 72 non-smokers (mean age, 31.88±9.94 years) between the ages of 20 and 60 years. Assessments included a 6-minute walking test (6MWT), Godin Leisure-Time Physical Activity Questionnaire, Health-Promoting Lifestyle Profile II (HPLP-II), Cardiovascular Risk Factors Knowledge Level Scale (CARRF-KL), Asthma/COPD Awareness Questionnaire, the World Health Organization Quality of Life-Bref questionnaire (WHOQoL-Bref TR), and Health Literacy Questionnaire (HLQ).
The results from the study show that the number of coronary artery disease risk factors measured significantly higher among the smoker group members when compared to that of the non-smoker group members (p=0.001). Smokers had significantly lower %6MWT distance than non-smokers (84.83±4.72 and 93.45±7.16, respectively; p<0.05). However, there were no significant differences between the smokers and non-smokers in terms of physical activity, CARRF-KL, HLQ, WHOQoL-Bref, and HPLP-II subscales or total scores (p>0.05). Additionally, while only forty-one smokers (57.7%) were active, 48 of the non-smoker group was active (66.7%).
Smokers suffer greater negative effects to their exercise capacity in comparison to non-smokers. Although smokers and non-smokers have similar levels of health literacy and similar levels of knowledge about cardiovascular disease risk factors and obstructive lung diseases, health professionals could continue to further increase individuals' awareness of smoking-related risk factors and continue to emphasize the importance of physical activity and exercise for protecting cardiopulmonary health.
Purpose The aim of this study was to compare functional capacity and peripheral muscle strength in preterm children with bronchopulmonary dysplasia (BPD) with those of age-matched full-term healthy ...controls. Subjects and Methods Eighteen BPD subjects and 20 healthy subjects were enrolled in the study. Pulmonary function testing was performed. Body composition was determined using the skinfold method. An analysis of posture was scored. Muscle strength was evaluated using a dynamometer. Functional capacity was assessed using the six-minute walking test (6MWT). Results Pulmonary function testing parameters, 6MWT distance, and quadriceps strength of the children with BPD were significantly lower than those of healthy peers. The scores of posture analysis of the children with BPD were significantly higher than those of healthy subjects. Exercise heart rate was significantly higher in the children with BPD compared to healthy children. The 6MWT distance correlated with height, fat-free mass, exercise dyspnea perception, and hand grip strength in BPD children. Conclusion The study showed that preterm children with BPD had disturbed pulmonary and extrapulmonary characteristics. BPD had lower fat free mass, reduced lung function, worsen postural function, a shorter 6MWT distance, and lower quadriceps strength than healthy children. These features may provide insights into the choice of outcome measures for pulmonary rehabilitation for BPD.

Background
Although both self‐paced and externally paced field tests are widely used in cystic fibrosis (CF), it is still unclear whether they induce clinically relevant and similar cardiorespiratory ...responses. The aim of this study was therefore to compare the incremental shuttle walk test (ISWT) and 6 min walk test (6MWT), and to determine the factors influencing exercise capacity in CF.
Methods
Fifty clinically stable CF patients were included in the study. Pulmonary function, peripheral and respiratory muscle strength were assessed, anthropometric measurements were recorded, and 6MWT and ISWT carried out.
Results
The CF patients covered significantly more distance in the ISWT than 6MWT (P < 0.001). Heart rate response and dyspnea score at the end of the tests and during the recovery phase were significantly higher in the ISWT compared with the 6MWT (P < 0.05). The 6MWT and ISWT had similar moderate–strong correlations with age, height, weight, pulmonary function, respiratory and peripheral muscle strength (P < 0.05). Forty‐nine percent of the variance in 6MWT distance was explained by age and forced expiratory volume in 1 s (FEV1; R2 = 0.49, F(2–48) = 22.033, P < 0.001). The variables contributing to ISWT distance were FEV1, inspiratory muscle strength, and body mass index (R2 = 0.596, F(3–44) = 20.176, P < 0.001).
Conclusions
The ISWT is a better reflection of exercise tolerance in CF than 6MWT. ISWT is a preferable alternative assessment of exercise tolerance in terms of cardiorespiratory response.
