The purpose of the present study was to identify mitochondrial DNA (mtDNA) polymorphisms and rare variants that associate with elite Japanese athletic status. Subjects comprised 185 elite Japanese athletes who had represented Japan at international competitions (that is, 100 endurance/middle-power athletes: EMA; 85 sprint/power athletes: SPA) and 672 Japanese controls (CON). The entire mtDNA sequences (16?569?bp) were analyzed by direct sequencing. Nucleotide variants were detected at 1488 sites in the 857 entire mtDNA sequences.

The sirtuin family of proteins consists of seven members in mammals (SirT1-T7). Sirtuins share NAD dependency for their enzymatic activity, but some show NAD-dependent deacetylase activity, others exhibit ADP ribosyltransferase activity or both. Sirtuins have gained considerable attention due to their impact as physiological targets for treating diseases associated with aging. Sirtuins interact with metabolic pathways and may serve as entry points for drugs. This review discusses the biology of sirtuins and their potential as mediators of caloric restriction and pharmacological targets.

Little is known about the biopsychological underpinnings of expert performance in team sports. In this paper we show that there is a vast support for oxytocin as a neuropeptide involved in the encouragement of important processes linked to greater team performance in sport.

This study evaluated the effects of hypnosis on self-efficacy and soccer performance. Fifty-nine collegiate soccer players were randomly allocated to either a hypnosis (n = 30) or video attention-control group (n = 29). A pretest-posttest design with an additional 4-week follow-up was used. Self-efficacy was measured via a task-specific questionnaire comprising 10 items relating to good performance on a soccer wall-volley task. The hypnotic intervention comprised three sessions using ego-strengthening suggestions. The control group watched edited videos of professional soccer games.

A model for the use of clinical hypnosis with a Little League population was proposed and outlined with dual emphasis: performance enhancement and resolving traumatic experiences. The Performance Enhancement Training Model was developed to enhance performance with this non-patient population. It employed clinical hypnosis to bring to fruition recommendations made by coaches to enhance players' batting proficiency.

This study examined the effects of a hypnosis intervention on the performance and flow-state experiences of an elite senior European Tour golf professional. The experimental effect was assessed during 11 Senior European Tour golf events. Performance and flow data were analyzed using a single-subject design combined with a procedure to monitor the player's internal experience. The results indicated that the player's mean stroke average and mean flow scores increased from baseline to intervention.

Massage is a commonly utilized therapy within sports, frequently intended as an ergogenic aid prior to performance. However, evidence as to the efficacy of massage in this respect is lacking, and massage may in some instances reduce force production. The aim of this study was to investigate the effect of massage on subsequent 30-m sprint running performance. Male university level repeat sprint sports players volunteered for the study (n = 37).

INTRODUCTION: Nutritional supplements used by athletes can be classified as sports food, dietary supplements and ergogenic aids. The aim of this study was to examine the use of such supplements among university athletes in Singapore. METHODS: 82 athletes from 16 sport disciplines completed a questionnaire which sought information on demographical parameters, type of supplements, frequency of use, motivations, knowledge, expenditure and side effects. RESULTS: The prevalence of supplement use was 76.8 percent and 20 different products were used.
