PURPOSE CrossFit(®) is a new but extremely popular method of exercise training and competition that involves constantly varied functional movements performed at high intensity. Despite the popularity of this training method, the physiological determinants of CrossFit performance have not yet been reported. The purpose of this study was to determine whether physiological and/or muscle strength m...
objective: alpha-thalassemia is one of the most prevalent hemoglobin disorders in the world and it is a common hereditary condition caused by deletion of one or more α-globin genes. common α-thalassemia deletions like 3.7 kb, 4.2 kb, 20.5 kb and med can be detected by multiplex pcr. there are, however, some unknown deletions that can not be detected by the mentioned method or even by direct dna...
the effect of different training modes on serum apelin and pain threshold in morphine-dependent rats
conclusions the results showed that endurance training reduced pain by increasing apelin in morphine-dependent rats. therefore, it is suggested that this type of training be considered for the morphine-dependent patients for pain relief. objectives therefore, the aim of this study was to evaluate apelin and pain threshold changes in healthy and morphine-dependent rats in response to two exercis...
background: acupuncture is an indispensable part of traditional chinese medicine for relief of pain. the purpose of this study was the immediate & latent of low power laser ga-al-as irradiation applied to acupuncture points on experimental pain threshold. methods: this quasi-experimental study was conducted on seventy adult women ranging from 20 to 40 years old assigned randomly into two groups...
Two modified go/no-go tasks are compared for the measurement of frequency discrimination in albino rats. The first task required detection of an instantaneous, phase-matched frequency change, called a "tone-step," within a continuous reference tone. The more traditional second task required detection of a frequency change between repetitions of a reference sequence of repeating discrete tones. ...
In a forward-masked intensity discrimination task, we manipulated the perceived lateralization of the masker via variation of the interaural time difference (ITD). The maskers and targets were 500 Hz pure tones with a duration of 30 ms. Standards of 30 and 60 dB SPL were combined with 60 or 90 dB SPL maskers. As expected, the presentation of a forward masker perceived as lateralized to the othe...
The dependence of O(2) uptake (V(O(2))) kinetics on the muscle mass recruited under conditions when fiber and muscle recruitment patterns are similar following the onset of exercise has not been determined. We developed a motorized cycle ergometer that facilitated one-leg (1L) cycling in which the electromyographic (EMG) profile of the active muscles was not discernibly altered from that during...
The Modified Bark Spectral Distortion (MBSD), used for an objective speech quality measure, was presented previously [1, 2]. The MBSD measure estimates speech distortion in loudness domain taking into account the noise masking threshold in order to include only audible distortions in the calculation of the distortion measure. Preliminary simulation results have shown improvement of the MBSD ove...
