Adventure-based teaching can foster social and personal growth yet can scare and cause long-lasting anxiety in some group members. This study examined the effects of a simple distraction to lower stress levels during an approaching scary event. Forty-eight males (M = 20.2 years) were randomly assigned to one of four groups. The stressor involved…

Fetal androgen exposure may be associated with autism spectrum disorder (ASD). We studied 1777 mother-child pairs in the prospective Odense Child Cohort. Prenatal androgen exposure was assessed by maternal 3rd trimester testosterone concentrations, maternal polycystic ovary syndrome (PCOS), and 3 months offspring anogenital distance. ASD traits…

Objective: Heightened nocturnal blood pressure (BP) may be attributed to the disruption of sleep, a condition worsened by alcohol ingestion. This study investigated the effects of acute alcohol ingestion on hemodynamics and sleep architecture in a young, healthy cohort of male. METHODS: Subjects (n = 17) underwent acute alcohol ingestion reaching…

Autism Spectrum Disorder (ASD) is a serious neurodevelopmental disorder with no clinical biomarker. This study used untargeted metabolomic analysis to identify metabolic characteristics in plasma that can distinguish ASD children. 29 boys with ASD (3.02 ± 0.67 years) and 30 typically developing (TD) boys (3.13 ± 0.46 years) were recruited.…

This study evaluated the reliability of the portable Lactate Pro 2 analyzer (LP2), and its validity compared to a laboratory-based analyzer, YSI 1500 Sport (YSI). Blood samples (n = 258) were collected during 44 graded incremental rowing tests, with data from 17 tests used to quantify load, heart rate, and oxygen consumption at lactate threshold.…

Purpose: To compare the effects of a single bout of eccentric cycling (ECC) and eccentric cycling with blood flow restriction (ECC[subscript BFR]) on the changes in cardio-metabolic demand and indirect markers of muscle damage in healthy men. Method: Twenty-one young men (24.0 ± 3.2 y) were randomly allocated in two groups to perform a 30-min…

Purpose: The purpose of this study was to investigate (a) time-dependent changes in muscle damage (MD) biomarkers, oxidative stress (OS) indices, and maximum strength performance; (b) the relationship between changes in maximum strength performance and changes in MD and OS indices; and (c) whether eccentric exercise-induced MD is related to OS.…

Ischemic preconditioning (IPC) has recently been experimented with the hypothesis that it can acutely improve exercise performance. IPC's ergogenic effects have been a novel approach to improve anaerobic power and sprint performances. Since the beneficial effects of the underlying mechanisms on anaerobic power have not been clearly understood, the…

This study aims to investigate the effect of acute handball training on the irisin, leptin, insulin and blood lipids. 19 male handball players, who are between 15-17, regularly train and play for Turkish Super Young League, have been volunteer for this research. All of the members of this research group are healthy and play handball for at least 3…

Sleep deprivation in healthy adults has been associated with disrupted autonomic nervous system function, which in turn has been linked to cardiovascular health. High-intensity interval exercise (HIIE) may affect both sleep and cardiac autonomic modulation. Purpose: To investigate the impact of acute partial sleep deprivation on autonomic cardiac…

Purpose: This study examined the relationships between the Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1) and resting heart rate variability (HRV) and submaximal 5'-5' test derived measures in novice male soccer players. Methods: Forty players (11.54 [plus or minus] 0.58 years) from a soccer academy participated in this study, performing…

Purpose and Methods: To compare the effects of a set of 12--30 min, maximal effort, constant load cycle bouts (HICT) to 12 short work: shorter rest (10 s: 5 s) interval sessions (INT) of similar duration and effort, performed on alternate days over 4 weeks, on performance and V?O[subscript 2] l.min[superscript -1]. INT sessions consisted of…

We explored sensory features as distinguishing characteristics of Autism spectrum disorder (ASD). Four groups of males (n = 36): Six with 47, XYY syndrome and ASD (XYY+ASD), six with 47, XYY syndrome and no ASD (XYY-ASD), 12 with idiopathic ASD (ASD-I) and 12 typically developing (TYP). The short sensory profile (SSP) the sensory challenge…

Purpose: The purpose of this study was to compare the acute effects of general warm-up (GWU) and GWU plus dynamic stretching (GWU + DS) on endurance running performance in well-trained male runners. Method: The endurance running performances of eight well-trained long-distance male runners were assessed on a treadmill after 2 types of intervention…

Maximal exercise capacity (W[subscript max]) and anaerobic threshold (A[subscript T]) are important tools used non-invasively to evaluate aerobic fitness levels and clinically possible risk. It has been shown that O[subscript 2] uptake to heartbeat ratio (O[subscript 2] pulse) at the maximal exercise test is an important parameter used to evaluate…
