Research into factors for suicide has revealed relations between trauma exposure and suicidality (e.g., Bridge, Goldstein, & Brent, ; Joiner, Sachs-Ericson, Wingate, Brown, Anestis, & Selby, ) wherein painful and provocative experiences (e.g., nonsuicidal self-injury [NSSI]) are an important link (e.g., Van Orden, Witte, Cukrowicz, Braithwaite, Selby, & Joiner, ; Smith, ). No prior research has assessed the relationship between functions of NSSI and suicidality among childhood trauma survivors. Participants who endorsed childhood trauma exposure (N = 121; Mage  = 18...

(1) BACKGROUND: studies with able-bodied athletes showed that performance might possibly be influenced by vitamin D status. Vitamin D seems to have a direct impact on neuromuscular function by docking on vitamin D receptors in the muscle tissue. Additionally, a high prevalence of vitamin D deficiency was shown not only in infants and in the elderly but also in healthy adults and spinal cord injured individuals. Therefore, the aim of our study was to investigate whether a vitamin D dose of 6000 IU daily over 12 weeks would be sufficient to increase vitamin D status in indoor wheelchair athletes to a normal or optimal vitamin D level and whether vitamin D deficiency is associated with an impairment in muscle performance in these individuals; (2) METHODS: vitamin D status was assessed in indoor elite wheelchair athletes in order to have a baseline measurement...

Adequate cerebral perfusion is necessary to maintain consciousness in upright humans. Following maximal anaerobic exercise, cerebral perfusion can become compromised and result in syncope. It is unknown whether post-exercise reductions in cerebral perfusion can lead to visual-cognitive deficits prior to the onset of syncope, which would be of concern for emergency workers and warfighters, where critical decision making and intense physical activity are combined. Therefore, the purpose of this experiment was to determine if reductions in cerebral blood velocity, induced by maximal anaerobic exercise and head-up tilt, result in visual-cognitive deficits prior to the onset of syncope...

Objective. Probiotics have been reported to support healthy digestive and immune function, aid in protein absorption, and decrease inflammation. Further, a trend to increase vertical jump power has been observed following co-administration of protein and probiotics in resistance-trained subjects. However, to date the potential beneficial effect of probiotics on recovery from high intensity resistance exercise have yet to be explored. Therefore, this study examined the effect of co-administration of protein and probiotics on muscle damage, recovery and performance following a damaging exercise bout...

PURPOSE: To examine the reliability and validity of a newly developed anaerobic and repeated sprint (RST0 performance capability. METHODS: A total of 35 untrained adolescent schoolchildren (age range 16-18 years) performed four tests: The newly developed 4 x 30 m RST, the Wingate Anaerobic Test (WAnT) and 200 m and 50 m sprint runs. The reliability of the test was assessed by comparing the test and retest performances of the test. The validity of the 4x30m RST was evaluated by computing the relationships among the various indices of the four studied anaerobic tests, and by comparing the effect of a well-defined anaerobic training program on the performance of the four anaerobic tests...

[Purpose] The aim of the present study was to examine the effects of respiratory muscle warm-up on anaerobic power. [Subjects and Methods] Thirty male field hockey players (age, 20.5 ± 2.0 years) each participated in a control (CAN) trial and an experimental (EAN) trial. The EAN trial involved respiratory muscle warm-up, while the CAN trial did not. Anaerobic power was measured using the Wingate protocol. Paired sample t-tests were used to compare the EAN and CAN trials. [Results] There were significant increases in peak power and relative peak power, and decreases in the time to peak after the EAN trial by 8...

Despite the potential of repetitive transcranial magnetic stimulation (rTMS) to improve performances in patients suffering from motor neuronal afflictions, its effect on motor performance enhancement in healthy subjects during a specific sport task is still unknown. We hypothesized that after an intermittent theta burst (iTBS) treatment, performance during the Wingate Anaerobic Test (WAnT) will increase and supraspinal fatigue following the exercise will be lower in comparison to a control treatment. Ten subjects participated in two randomized experiments consisting of a WAnT 5 min after either an iTBS or a control treatment...
