Psychobiosocial states in competitive badminton: Similarities and differences between juniors, adolescents and adults

Emotions affect the way elite athletes respond during competitive play. Elite athletes who identify and regulate emotions can increase their consistency and optimize high quality play. This cross-sectional study examined the extent to which psychobiosocial states of elite badminton players vary by age. Ninety-one elite badminton players in three age groups (lower juniors, upper juniors, and adults) rated their post-play perceptions on eight components of psychobiosocial states (Bortoli, et al., 2008) for both their best and worst performance during the tournament. Descriptive statistics assessed the relative strength of emotions on each item and an analysis of variance examined differences between the three groups. Age differences were found in the perception of the psychobiosocial states in competitive badminton matches in terms of most identified states and intensity. The findings inform coaches’ understanding athlete's individual zone of optimal function (IZOF) and can help them cope with psychobiosocial states during matches

Human Fatal Zaire Ebola Virus Infection Is Associated with an Aberrant Innate Immunity and with Massive Lymphocyte Apoptosis

Ebolavirus, especially the species Zaïre (ZEBOV), causes a fulminating hemorrhagic fever syndrome resulting in the death of most patients within a few days. In vitro studies and animal models have brought some insight as to the immune responses to ZEBOV infection. However, human immune responses have as yet been poorly investigated, mainly due to the fact that most outbreaks occur in remote areas of central Africa. Published studies, based on small numbers of biological samples have given conflicting results. We studied a unique collection of 50 blood samples obtained during five outbreaks that occurred between 1996 and 2003 in Gabon and Republic of Congo. We measured the plasma levels of 50 soluble factors known to be involved in immune responses to viral diseases. For the first time, using a cell staining technique, we analyzed circulating lymphocytes from ZEBOV-infected patients. We found that fatal outcome in humans is associated with aberrant innate immunity characterized by a “cytokine storm,” with hypersecretion of numerous proinflammatory mediators and by the noteworthy absence of antiviral interferon. The adaptive response is globally suppressed, showing a massive loss of CD4 and CD8 lymphocytes and the immune mediators they produce. These findings may have important pathological and therapeutic implications
