In this study, we compared measured maximal heart rate (HRmax) to two different HRmax prediction equations [220-age and 208-0.7(age)] in 52 children ages 7-17 years. We determined the relationship of chronological age, maturational age, and resting HR to measured HRmax and assessed seated resting HR and HRmax during a graded exercise test.…

Individuals with intellectual and developmental disabilities (IDD) are in need of effective and motivating physical fitness training programs. The aim was to test the effectiveness of a virtual reality (VR)-based exercise program in improving the physical fitness of adults with severe IDD when implemented by on-site caregivers. A research group (N…

Autism spectrum disorder (ASD) as defined by the revised Diagnostic and Statistical Manual of Mental Disorders: DSM IVTR criteria (American Psychiatric Association [2000] Washington, DC: American Psychiatric Publishing) as impairment before the age of 3 in language development and socialization with the development of repetitive behaviors, appears…

Successful physical educators should always search for fun and effective ways to keep their students fit and active. According to Garber, McKinney, and Carleton (1992), an aerobic dance program can be "an effective alternative to a traditional walk-jog training regime." Such a program can provide students with a unique, creative, and worthwhile…

Ten adolescent judokas performed circuit training consisting of six 40-s periods of judo exercises separated by 40 s (CT1:1), 120 s (CT1:3), or 200 s (CT1:5) of rest. Heart rate, blood lactate concentration, and the number of repetitions were recorded. Heart rate reached [approximately]180 beats[middle dot]min-1 at the end of work periods, with…

Arm swing in human walking is an active natural motion involving the upper extremities. Earlier studies have described the interrelationship between arms and legs during walking, but the effect of arm swing on energy expenditure and dynamic parameters during normal gait, is inconclusive. The aim of this study was to investigate the effect of…

Background: Effective emotion regulation should be reflected in greater coherence between physiological and subjective aspects of emotional responses. Method: Youths with normative to clinical levels of internalizing problems (IP) and externalizing problems (EP) watched emotionally evocative film-clips while having heart rate (HR) recorded, and…

The education of new allied health professionals and nurses in proper endocrine evaluation and care has become critical in recent years, especially considering the greatly increased prevalence of diabetes in adults and children. The evaluation of blood glucose levels in human volunteers over time is a powerful teaching tool for endocrinology that…

The present functional magnetic resonance imaging (fMRI) study was designed, in order to investigate the neural substrates involved in the audiovisual processing of disyllabic German words and pseudowords. Twelve dyslexic and 13 nondyslexic adults performed a lexical decision task while stimuli were presented unimodally (either aurally or…

Pathological laughing and crying is a disorder of emotional expression seen in a number of neurological diseases. The aetiology is poorly understood, but clinical descriptions suggest a disorder of emotion regulation. The goals of this study were: (i) to characterize the subjective, behavioural and physiological emotional reactions that occur…

Aim: It has been suggested that high levels of prenatal testosterone exposure are implied in the aetiology of attention-deficit-hyperactivity disorder (ADHD). This study examined the association between the ratio of the length of the second and fourth digits (2D:4D ratio), a marker of fetal testosterone exposure, and the presence of ADHD-related…

To examine the ontogeny of emotion-attention interactions, we investigated whether infants exhibit adult-like biases in automatic and voluntary attentional processes towards fearful facial expressions. Heart rate and saccadic eye movements were measured from 7-month-old infants (n = 42) while viewing non-face control stimuli, and neutral, happy,…

Following hypoxia-ischaemia (HI), an early biomarker of insult severity is desirable to target neuroprotective therapies to patients most likely to benefit; currently there are no biomarkers within the "latent phase" period before the establishment of secondary energy failure. Brief transient phosphocreatine (PCr) recovery overshoot (measured…

Incorporating technology into the physical education curriculum is becoming a popular strategy in which teachers can assess, motivate, and provide feedback to students regarding their physical activity participation during class. The purpose of this exploratory study was to gain a greater understanding of high school students' perceptions of using…

The current study is one of the first prospective examinations of longitudinal associations between observed father caregiving behaviors and child cortisol reactivity and regulation in response to emotional arousal. Observations of father and mother caregiving behaviors and child cortisol levels in response to challenges at 7 months and 24 months…
