An experimental strategy for determining the extent to which multiply isotopically labeled fragments are incorporated intact into relatively complicated compounds of interest is presented. The NMR methods employed are based on isotope-filtered one-dimensional spectra and difference HSQC spectra incorporating a spin echo designed to report on the presence of a second NMR active isotope at a coup...
The purpose of this study was to examine the effect of self-control feedback on the learningof generalized motor program and parameters during physical and observational practice. Participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked and instructor KR) groups. They practiced a sequential timing task. The task required participants to press four k...
Objective: Theories are in paradox in relation to the variability pattern with being skilled. Then this research has investigated two types of absolute and coordination variability during basketball free throw learning, with isolating mechanical and dynamical degrees of freedom. Methods: Twenty self-declared participants were randomly assigned into two groups: physical practice and control. Ex...
Background. Although some research showed the benefits of a systematic increase in contextual interference (CI), it is not completely proved in young children and novices. Objectives. On the other hand, considering the recommendation of researchers about the advantages and the use of the mental practice, the aim of the present study was to combine mental practice with CI to improve motor perfo...
background: non communicable diseases (ncd) will account for 73% of deaths and 60% of the global disease burden by 2020. physical activity plays a major role in the prevention of these non‑communicable diseases. the stress involved in meeting responsibilities of becoming a physician may adversely affect the exercise habits of students. so, the current study aimed to study the practice of physic...
Objectives: Mental practice, as a neuropsychological factor effective in motor recovery, is a cognitive rehearsal of a physical skill without muscular activity. Considering the high level of fatigue in patients with Multiple Sclerosis (MS), we hypothesized that using mental practice as a low-level energy-consuming method added to physical practice could be a useful therapeutic strategy. Therefo...
Background. Recent research has proposed that environmental factors affect the development of expertise. Objectives. The present study aimed to compare the history of training activities amongst expert athletes of different sport disciplines regarding the level of risk. Methods. Participants included 187 athletes from six sports disciplines, which were allocated to "low-risk," "medium risk," o...
The taxonomy of cyanobacteria has been substantially modified in the last few decades, particularly after application of modern ultra structural and molecular methods. The present research, therefore, aimed to investigate, through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacteria strains isolated from different agricultural and freshwaters areas...
