Influence of Goal Contents on Exercise Addiction: Analysing the Mediating Effect of Passion for Exercise

et al., 2009 ). Indeed, Sebire et al. (2009) have shown that the way in which exercise is internalised into a person’s identity can be a mediator in this relationship. A construct which reflects the way a person internalizes the value attributed to a particular activity and thus submits to it, is that of passion ( Parastatidou et al., 2014 ). Dualistic Model of Passion The SDT suggests that people naturally orientate themselves towards activities that satisfy their needs (e.g. their relationships with other people, autonomy and competence), and that these

The mediation effect of Perceived Social Support and Perceived Stress on the relationship between Emotional Intelligence and Psychological Wellbeing in Male Athletes

Introduction Researchers have investigated the relationship between emotional intelligence (EI) and psychological wellbeing in a number of ways and from different disciplinary perspectives, examining various associations with other variables. The researchers within the field of sport and exercise psychology have focused on potential mediating variables which can account for this relationship, for instance, perceived social support ( Roohafza et al., 2016 ; Smith et al., 1995 ) and perceived stress ( Laborde et al., 2016 ; Raedeke and Smith, 2004 ; Roohafza

Ketogenic Diet and Skeletal Muscle Hypertrophy: a Frenemy Relationship?

; Volek et al., 2016 ; Webster et al., 2016 ). Histone acetylation mechanisms Histone acetylation plays numerous roles in muscle control and different classes of histone deactylase have different effects on skeletal muscle such as control of contracting proteins, calcium channels and, in general, muscle health. BHB mediates inhibition of histone deacetylase (HDAC) activity in vivo ( Roberts et al., 2017 ). HDAC inhibitors increased the lifespan by a still not very well known mechanism, yet associated with hyperacetylation of histones and a large number of other

Genetic Markers Associated with Power Athlete Status

sports level). The molecular aspects of this SNP have not been yet described and further studies on the role of rs7458 alleles are required. Another cytoskeletal protein that occurs together with actin myofilaments, and binds to myosin phosphatase and RhoA is a myosin phosphatase Rho interacting protein (MPRIP). This protein is known as a fusion partner of the receptor TK gene NTRK1 . A specific domain at the amino terminus of MPRIP has been shown to mediate actin binding in vivo . The human MPRIP gene is located in the 17p11.2 locus . The genome wide analyses

Which Factors Affect Hand Selection in Adults? Combined Effects of Ocular Dominance, Task Demand and Object Location

Which Factors Affect Hand Selection in Adults? Combined Effects of Ocular Dominance, Task Demand and Object Location

Eighty-five right-handed subjects (39 female and 46 male, 47 being right-eye dominant and 38 being left-eye dominant) were tested on three tasks of different levels of difficulty, performed in five locations. In the current study, participants were required to pick up the tool, pick up and pantomime how to use it and pick up and actual use on the materials provided. Our goal was to evaluate how the effect of object location interacts with task difficulty on adult hand selection. We also tried to evaluate the effect of eye dominance as a biological factor on hand selection. The result showed that the frequency of preferred hand reaches was greater for pantomime and real use than the pick up condition. This effect was mediated by the position of the object in hemispace, with more right hand reaches occurring for the use and pantomime task than the pick up task. The result also revealed that there is no difference between frequency of preferred hand reaches in left- and right-eye dominant. Based on results of this study, it can be suggested that limb selection depends on task and environmental constraints, rather than a biological factor like eye dominance.
