We tested the hypothesis that older men (n = 9, 69 +/- 2 years) would experience greater resistance-training-induced myofiber hypertrophy than older women (n = 5, 66 +/- 1 years) following knee extensor training 3 days per week at 65-80% of one-repetition maximum for 26 weeks. Vastus lateralis biopsies were analyzed for myofiber areas, myosin heavy chain isoform distribution, and levels of mRNA...

in arabic poetry, the device of repetition functions at two levels: form and meaning. in form, repetition makes for musical richness, and in meaning, it makes for emphasis. the present article is a study of repetition in “an address from the market of idleness” by palestinian poet samä«h al-qäsim. the poem depicts actual and possible palestinian sufferings inflicted by israelis and stresse...

This study highlights the blood lactate response of weightlifters (N = 5) in two modes of olympic lifts: Snatch (SN) and Clean & Jerk (CJ), during three types of training namely (1) one repetition lift (ORL), (2) Multiple set session (MSS) and (3) one set session (OSS). In ORL, 30, 40, 50, and 60 kg, each of one repetition only, were lifted with an interval of 5 min between two consecutive load...

BACKGROUND The role of deliberate practice in medical students' development from novice to expert was examined for preclinical skill training. METHODS Students in years 1-3 completed 34 Likert type items, adapted from a questionnaire about the use of deliberate practice in cognitive learning. Exploratory factor analysis and reliability analysis were used to validate the questionnaire. Analysi...

PURPOSE To investigate the relationship between repeated high-intensity-effort (RHIE) ability and selected physical qualities in rugby league players. METHODS Sixteen rugby league players underwent measurements of upper-body strength (4-repetitionmaximum [4RM] bench press, weighted chin-up, weighted dips), upper-body muscle endurance (body-mass maximum-repetition chin-up, body-mass maximum-re...

This work deals with methods for finding optimal neural network architectures to learn particular problems. A genetic algorithm is used to discover suitable domain specific architectures; this evolutionary algorithm applies direct codification and uses the error from the trained network as a performance measure to guide the evolution. The network training is accomplished by the back-propagation...

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training trials were conducted in which a stimulus of known le...

A. Scalable training The bottleneck of the training procedure is the expectation step (E-Step) of the Expectation-Maximization algorithm. This E-Step requires the computation of the first and second order moments of the latent variables. 1) Estimating the first order moment of the Latent Variables: The most computationally expensive part when estimating the latent variables is the inversion of ...

BACKGROUND We examined the relationship of musculoskeletal risk factors underlying force and repetition on tissue responses in an operant rat model of repetitive reaching and pulling, and if force x repetition interactions were present, indicative of a fatigue failure process. We examined exposure-dependent changes in biochemical, morphological and sensorimotor responses occurring with repeated...
