patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...

Inspiratory muscle dysfunction has been shown to be related to hypercapnia and hence, to ventilatory insufficiency in patients with chronic obstructive pulmonary disease (COPD) [1]. Accordingly, treatment of inspiratory muscle dysfunction has gained interest in the last decade. Among other treatment modalities, such as pharmacotherapy and respiratory muscle rest, training of the inspiratory mus...

BACKGROUND AND OBJECTIVES Dynamic hyperinflation (DH) and expiratory flow limitation (EFL) are physiologically linked and seem to be involved in the genesis of dyspnea and the quality of life (QL) impairment in chronic obstructive pulmonary disease (COPD). Advanced COPD patients often show expiratory muscles dysfunction that could be involved in DH development. AIM Study the relationships bet...

This study examines the relationships between ultrasonography measurements of skeletal muscle size and echo intensity (EI) with strength local endurance in a habitually resistance-trained population. Twenty young, healthy participants underwent imaging biceps brachii sagittal transverse planes extended field view (EFOV) technique. Linear regression was used to examine measures thickness (MT), c...

We used allometric models to identify the optimal body size/shape characteristics associated with physical and motor performance tests in Peruvian schoolchildren. The sample consisted of 3624 subjects (1669 boys and 1955 girls) aged 11-17 years from 31 public schools belonging to four cities located in the three natural regions in central Peru. Motor performance included 12-min run, standing lo...

101 youngsters aged 8 to 25 (mean 13.3 years) underwent a 5-stage fitness check at six different investigational sites. The 5-stage fitness check comprises a coordination measurement element measuring the excursion of a two-dimensional mobile floor platform (Posturomed) in millimeters over a period of 30 seconds with the subject standing on one leg. Flexibility testing analyzes chest muscles an...

Objective assessment Objective assessment of the pelvic floor muscles includes an abdominal, perineal, neurological and digital rectal examination. This assessment can be undertaken by a nurse or physiotherapist with specialist supervised training. The patient should be allowed to be chaperoned by a partner, friend or a member of staff. The objective assessment should always begin with an expla...

Abstract Purpose Gymnastics is a sport characterized by acrobatic and postural strength exercises that require great trunk muscles activation control. Males females can be different morphological neuromuscular characteristics of such muscles, this might importance for training injury prevention. The aim study was to measure aspects flexors extensors in sample young female male gymnasts. Methods...

BACKGROUND Exercise is one of the few treatments that provide significant improvements in chronic low back pain (CLBP). We developed an innovative exercise device for abdominal trunk muscles. This device can be used in a sitting or standing position and contains a built-in system to measure abdominal trunk muscle strength. We examined whether subjects can adequately use the device to perform th...

BACKGROUND The mining industry has one of the highest occupational rates of serious injury and fatality. Mine staff involved with rescue operations are often required to respond to physically challenging situations. This paper describes the physical attributes of mining rescue personnel. METHODS 91 rescue personnel (34 +/- 8.6 yrs, 1.79 +/- 0.07 m, 90 +/- 15.0 kg) participating in the Queensl...
