Previous studies have shown that induction of long-term potentiation (LTP) induces phosphorylation of ribosomal protein S6 (rpS6) in postsynaptic neurons, but the functional significance of rpS6 phosphorylation is poorly understood. Here, we show that synaptic stimulation that induces perforant path LTP triggers phosphorylation of rpS6 (p-rpS6)…

Purpose: To assess the role of interaural time differences and interaural level differences in (a) sound-source localization, and (b) speech understanding in a cocktail party listening environment for listeners with bilateral cochlear implants (CIs) and for listeners with hearing-preservation CIs. Methods: Eleven bilateral listeners with MED-EL…

Purpose: The purpose of this research was to learn the extent to which healthy individuals vary in their ability to achieve velopharyngeal closure for speech. Method: Twenty healthy adult volunteers (10 women, 10 men) were tested using an endoscopic phototransducer system that tracks variations in velopharyngeal closure during speech production.…

The purpose of this study was to investigate the effect of post-challenge acute values of serum cortisol levels in elite and sedentary athletes before aerobic exercise. This study included 22 elite middle-distance runners from various clubs around Turkey and 16 voluntary non-athlete men. The Cooper test was applied to study subjects. Heart rate…

This study aims to analyze running distances in national teams during 2010 and 2014 FIFA World Cup and to propose a new program which estimates oxygen consumption capacity based on running distances. The data were evaluated by SPSS 22.0 statistical package program. The findings demonstrate that among teams participating in 2010 and 2014 FIFA World…

Purpose: This experiment sought to determine whether children's increased susceptibility to nonsimultaneous masking, particularly backward masking, is evident for speech stimuli. Method: Five- to 9-year-olds and adults with normal hearing heard nonsense consonant-vowel-consonant targets. In Experiments 1 and 2, those targets were presented between…

Purpose: This study investigated the physiological effects of wearing a mouthguard during submaximal treadmill exercise. Method: Twenty-four recreationally active males (M[subscript age] = 21.3 ± 2.4 years, M[subscript height] = 1.78 ± 0.06 m, M[subscript weight] = 81.9 ± 10.6 kg, M[subscript body mass index] = 25.8 ± 3.4 kg·m[superscript -2])…

Music education is being explored by researchers as a means of improving hearing acuity for children with hearing loss, particularly those with cochlear implants. Music educators are uniquely positioned to contribute to this important endeavor. This article describes normal and impaired hearing and how music perception is affected for students…

Purpose: The purpose of this study was to determine the impact of adjunctive resistance training (RT) in aerobically trained patients with coronary artery disease on systolic blood pressure (SBP), heart rate (HR), rating of perceived exertion (RPE; using the traditional 6-to-20 scale), and rate-pressure product (RPP) responses to lifting fixed…

The main purpose of this research was to study the effect of rapid dehydration on some motor fitness of wrestlers. So 30 wrestlers were voluntarily selected and randomly divided into two groups (n=15); active and sauna groups. They participated in some motor fitness factors tests such as; reaction time, 9 × 4 meters test to measure agility and 60…

The main purpose of this research was to investigate the effect of weight loss on some physical fitness factors of wrestlers. So thirty wrestlers were voluntarily selected and randomly divided into two groups (n=15); active and sauna groups. They participated in some motor fitness factors tests such as; Sargent tests to measure the anaerobic…

Many undergraduate students in kinesiology are interested in clinical careers and seek research opportunities for advanced study and unique learning experiences. This article describes a process of engaging undergraduate students in a multi-disciplinary, National Institutes of Health (NIH)-funded program project investigating factors that may…

Purpose: The purpose of this study is to quantify the interactions of the 3 vocalization subsystems of respiration, phonation, and resonance before, during, and after a perturbation to the larynx (temporarily induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Using dynamic systems theory as a guide, we hypothesized that…

The role of flexibility on athletic performance is going on to be studied both acutely and how it affects the performance in the long-term. It is important to understand the effects of various stretching types and define the most appropriate form in order to maximize the human movement and performance. Proprioceptive neuromuscular facilitation…

Canadian post-secondary institutions are increasingly introducing a fall break into their term calendars, with the stated goal of reducing student stress and improving academic success. We conducted a pilot study around the time of this fall break during which we collected saliva samples to measure the ratio of two metabolic hormones (cortisol and…
