We sought to determine whether the angiotensin-converting enzyme (ACE) insertion (I)/deletion (D) polymorphism is associated with submaximal exercise cardiovascular hemodynamics. Postmenopausal healthy women (20 sedentary, 20 physically active, 22 endurance athletes) had cardiac output (acetylene rebreathing) measured during 40, 60, and 80% VO(2 max) exercise. The interaction of ACE genotype an...

OBJECTIVE To evaluate within- and between-days reliability of two normalization methods of surface electromyography (sEMG) recordings of the trapezius muscle. METHODS Nineteen women were allocated into 2 groups (healthy and with neck-shoulder pain). The sEMG was recorded in two sessions with 7 days in between sessions. The four portions of the trapezius muscle (the clavicular and acromial fib...

Monitoring training progress during exercise training in cancer survivors: a submaximal exercise test as an alternative for a maximal exercise test? Arch Phys Med Rehabil 2010;91:351-7. Objective: To examine the use of a submaximal exercise test in detecting change in fitn...

Compared with maximal exercise testing, submaximal exercise testing appears to have greater applicability to physical therapists in their role as clinical exercise specialists. This review contrasts maximal and submaximal exercise testing. Two major categories of submaximal tests (ie, predictive and performance tests) and their relative merits are described. Predictive tests are submaximal test...

BACKGROUND Submaximal oxygen uptake measures are more feasible and may better predict clinical cardiac outcomes than maximal tests in older adults with heart failure (HF). We examined relationships between maximal oxygen uptake, submaximal oxygen kinetics, functional mobility, and physical activity in older adults with HF and reduced ejection fraction. METHODS Older adults with HF and reduced...

We examined how obese children perceive a maximal cardiorespiratory fitness test compared with a submaximal cardiorespiratory fitness test. Twenty-one obese children (body mass index ≥95th percentile, ages 10-17 years) completed maximal and submaximal cardiorespiratory fitness tests on 2 separate occasions. Oxygen consumption (VO2) and overall perceived exertion (Borg 15-category scale) were me...

background and aims: due to the anti-inflammatory properties of the ginger plant, it has attracted researchers’ attentions for treating menstrual problems. the aim of this study was to investigate the effect of a program which contains submaximal aerobic exercises and ginger on pain duration in the college girls with primary dysmenorrhea. methods: this quasi-experimental research was performed ...

introduction: exercise training increases skeletal muscle capillary density, but the molecular mechanisms of this process are not yet clear. the aim of the present study was to investigate the effect of acute long- term submaximal exercise on serum vascular endothelial growth factor (vegf) as the main angiogenic factor, and matrix metalloproteinases 2 and 9 ( mmp-2 and mmp-9), as the degrading ...
