The 15-step oximetry test: a reliable tool to identify candidates for lung transplantation among patients with idiopathic pulmonary fibrosis.
Shitrit D, Rusanov V, Peled N, Amital A, Fuks L, Kramer MR
This study was design to determine whether the simple 15-step climbing exercise oximetry test accurately characterised disease severity and survival in patients with idiopathic pulmonary fibrosis (IPF). Results of performance on the 15-step climbing test, pulmonary function tests… Continue reading
Gluteal Muscle Activation During Common Therapeutic Exercises.
Distefano LJ, Blackburn JT, Marshall SW, Padua DA
The objective of this study was to quantify and compare electromyographic signal amplitude of the gluteus maximus and gluteus medius muscles during exercises of varying difficulty to determine which exercise most effectively recruits these muscles. Surface electromyography was used to quantify the activity level of the gluteal muscles in 21 healthy, physically active subjects while performing 12 exercises. Gluteus medius activity was significantly… Continue reading
Rationale of the combined use of inspiratory and expiratory devices in improving maximal inspiratory pressure and maximal expiratory pressure of patients with chronic obstructive pulmonary disease.
Battaglia E, Fulgenzi A, Ferrero ME
Thirty-two adults with a mean age of 68 years and mild to very severe COPD were randomised into two groups. The control group received sham training on devices with a training load insufficient to improve maximal inspiratory pressure (MIP) or maximal expiratory
Within-day repeatability of the endurance shuttle walk test
Revill S.M, Williams J., Sewell L., Collier R., Singh S.J.
This study was designed to determine the need for a practice walk for the endurance shuttle walk test (ESWT) following the performance of two incremental shuttle walk tests (ISWTs) – one practice and one test – on the same day… Continue reading
Distance and Oxygen Desaturation During the 6-min Walk Test as Predictors of Long-term Mortality in Patients With COPD
Casanova C, Cote C, Marin JM, Pinto-Plata V, de Torres JP, Aguirre-Jaíme A, Vassaux C, Celli BR.
In this study 576 stable COPD outpatients in Spain and the United States were enrolled and observed them for at least 3 years. FEV1, body mass… Continue reading
Prognostic Usefulness of Dyspnea Versus Fatigue as Reason for Exercise Test Termination in Patients With Heart Failure
Chase P, Arena P, Myers J, Abella J, Paberdy MA, Guazzi M, Kenjale A, Bensimhon D.
This investigation examined differences in cardiopulmonary exercise testing (CPX) variables and prognosis according to reason for test termination. One hundred eighty-three patients with… Continue reading
A cardiopulmonary exercise testing score for predicting outcomes in patients with heart failure.
Meyers J, Arena R, Dewey F, Bensimhon D, Abella J, Hsu L, Chase P, Guazzi M, Peberdy MA
This study set out to evaluate the predictive accuracy of a cardiopulmonary exercise test (CPX) score. Cardiopulmonary exercise test responses, including peak VO2, markers of ventilatory inefficiency, and hemodynamic responses are strong… Continue reading
Repeated sets or single set of resistance training – A systematic review
Sofia Bågenhammar ; Eva Ekvall Hansson
The aim of the study was to review studies concerning single-set and multiple-set resistance training. Twenty-six articles were found, 19 randomized controlled trials and seven studies without randomization process. Out of the 26 articles, 11 showed similar increases in strength when comparing number of sets, mostly one set compared with three sets. Eight of the articles showed a greater increase when training with multiple… Continue reading
Sensitivity, specificity and predictive value of the clinical trunk muscle endurance tests in low back pain
Massoud Arab, A., Salavati, M., Ebrahimi, I., Ebrahim Mousavi, M.
The objective of this study was to describe the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of five clinical tests used to measure trunk muscle endurance in low back pain. A convenience sample of 200 subjects were categorized into four groups: men without low back pain, women without low back pain, men with low back pain and women with low back… Continue reading
Comparison of Recovery Strategies on Muscle Performance After Fatiguing Exercise.
Mika, Anna; Mika, Piotr; Fernhall, Bo; Unnithan, Viswanath B.
The objective of this study was to assess the influence of different relaxation modes: stretching (ST), active recovery (AR), and passive recovery (PR) on muscle relaxation after dynamic exercise of the quadriceps femoris. Ten healthy male volunteers between 24 and 38 yrs of age participated in this study. After the warm-up, subjects performed three sets of dynamic leg extension… Continue reading
