The effects of pre-task music on choice visual reaction time in elite taekwondo athletes.

OBJECTIVES: The effects of music on sport performance mainly involved endurance or resistance exercises overlooking possible effects on reaction time, which is deemed essential in martial arts for a proficient performance. Therefore, the aim of this study was to investigate the effects of the exposure to pre-task music on choice visual reaction time in elite taekwondo athletes. DESIGN: Repeated measure study design. METHODS: Reaction time and mean Heart Rate (HRmean) were recorded in twenty young taekwondo athletes (17.5 ±â€¯2.5 years old) while performing a roundhouse kick in response to different visual stimuli after three warmup conditions: listening to self-selected music (SM), research-selected music (RM) or no music (CC). Moreover, Feeling Scale (FS), Felt Arousal Scale (FAS) were recorded before (T0) and after warmup (T1) in each testing session. RESULTS: SM and RM elicited significantly faster reaction times compared to CC (-3.3 % and -5.2 %, respectively). No significant difference in reaction time was observed between SM and RM. The FS and FAS scores were significantly higher at T1 compared to T0 in the SM and RM conditions, whereas no difference between T0 and T1 was observed in the CC condition. No difference was observed for HRmean between SM, RM and CC conditions. CONCLUSIONS: Listening to SM and RM during the warmup improved choice visual reaction times in elite taekwondo athletes. These results suggest the use of music as a performance-enhancing strategy prior to combat competition or training in martial arts.

Positive effects of dietary supplementation with nutraceuticals on male subclinical hypogonadism: a pilot study.

BACKGROUND: Lifestyle modifications (i.e., physical activity [PA] and lower dietary intake) often are not sufficient to improve testosterone (TE) levels and promote weight loss in men with metabolic hypogonadism. The aim of the study was to investigate the effects of a nutraceutical formulation containing myoinositol, alpha lipoic acid, folic acid and SelectSIEVE® as add-on treatment to lifestyle modifications in improving obesity-related subclinical hypogonadism. METHODS: Body composition, insulin resistance, testicular and erectile function were investigated in 15 males (age=39.5±14.5 years; Body Mass Index [BMI]=30.2±3.8 kg/m2, with subclinical hypogonadism (TE levels <14 and normal luteinizing hormone [LH]). After a run-in three months unsupervised PA period (T1), the nutraceutical supplement was administered two-times per day for three additional months (T2). RESULTS: BMI, the percentage fat mass, insulinemia and Homeostasis Model Assessment Index (P<0.01) along with glycemia (P<0.05) were significantly reduced at T2 compared to T1, respectively; fat free mass (FFM) was significantly higher at T2 compared to T1 (P<0.01). Also, TE, LH and 5-item international index of erectile function score were significantly increased at T2 compared to T1 (P<0.01), respectively. CONCLUSIONS: The combination of unsupervised PA and nutraceutical supplement improves body composition, insulin sensitivity and TE production in overweight-obese men with metabolic hypogonadism. Further controlled studies in the long-term are warranted to elucidate potential changes in fertility.

Emerging nanomedicine applications and manufacturing: progress and challenges.

APS 6th International PharmSci Conference 2015 7-9 September 2015 East Midlands Conference Centre, University of Nottingham, Nottingham, UK As part of the 6th APS International PharmSci Conference, a nanomedicine session was organised to address challenges and share experiences in this field. Topics ranged from the reporting on latest results and advances in the development of targeted therapeutics to the needs that the community faces in how to progress these exciting proof of concept results into products. Here we provide an overview of the discussion and highlight some of the initiatives that have recently been established to support the translation of nanomedicines into the clinic.
