The effects of taurine on repeat sprint cycling after low or high cadence exhaustive exercise in females

This study investigated the effects of taurine on repeated sprint exercise, performed after fixed incremental ramp exercise to exhaustion at isokinetic high (90 r/min) or low (50 r/min) cadences. In a double-blind, repeated measures design, nine females completed an incremental ramp test to volitional exhaustion, followed by 2 min active recovery and 6 × 10 s sprints on a cycle ergometer, in one of four conditions: high cadence (90 r/min) + taurine (50 mg/kg body mass); high cadence + placebo (3 mg/kg body mass maltodextrin); low cadence (50 r/min) + taurine; low cadence + placebo. Heart rate (HR) and blood lactate concentration B[La] were measured before and after the ramp test and after the sprints. Taurine lowered HR vs. placebo prior to the ramp test (P = 0.004; d = 2.1). There was an effect of condition on ramp performance (P < 0.001), with higher end-test power (d = 3.7) in taurine conditions. During repeated sprints, there was a condition × time interaction (P = 0.002), with higher peak sprint power in the placebo conditions compared to taurine (sprint 2–6; P < 0.05). B[La] was higher in taurine compared to placebo post-ramp (P = 0.004; d = 4.7). Taurine-lowered pre-exercise HR and improved incremental end-test power output, with subsequent detrimental effects on sprint performance, independent of cadence. Short endurance performance can be acutely enhanced after taurine ingestion but this effect might not be maintained across longer periods of exercise or induce the need for longer recovery periods

The Effects of an Oral Taurine Dose and Supplementation Period on Endurance Exercise Performance in Humans: A Meta-Analysis

BackgroundTaurine is central to many physiological processes, some of which are augmented by exogenous supply and have the potential to facilitate endurance performance; however, its independent effects on performance have not been systematically analysed.ObjectiveTo evaluate the effects of isolated oral taurine ingestion on endurance performance and to assess the contribution of (1) the dose and (2) the supplementation period to the ergogenic effect.MethodsA search was performed using various databases in September 2017. The studies were screened using search criteria for eligibility. Ten peer-reviewed articles were identified for inclusion. A sub-analysis of time-to-exhaustion (TTE) trials (n = 7) was also performed. The effects of (1) dose and (2) the acute (single dose) or chronic (> 1 day) supplementation periods were assessed using meta-regression. The doses of taurine ranged from 1 to 6 g/day and were provided in single doses and for up to 2 weeks among a range of subjects.ResultsTaurine ingestion improved overall endurance performance (Hedges’ g = 0.40, 95% CI 0.12–0.67, P = 0.004), which was similar in TTE trials (Hedges’ g = 0.43, 95% CI 0.12–0.75, P = 0.007). There were no differences between acute or chronic supplementation for the full sample (P = 0.897) or the TTE group (P = 0.896). The dose of taurine did not moderate its effect on endurance performance (P > 0.05).ConclusionHuman endurance performance can be improved by orally ingesting a single dose of taurine in varying amounts (1–6 g)

An enigma in the genetic responses of plants to salt stresses

Soil salinity is one of the main factors restricting crop production throughout the world. Various salt tolerance traits and the genes controlling these traits are responsible for coping with salinity stress in plants. These coping mechanisms include osmotic tolerance, ion exclusion, and tissue tolerance. Plants exposed to salinity stress sense the stress conditions, convey specific stimuli signals, and initiate responses against stress through the activation of tolerance mechanisms that include multiple genes and pathways. Advances in our understanding of the genetic responses of plants to salinity and their connections with yield improvement are essential for attaining sustainable agriculture. Although a wide range of studies have been conducted that demonstrate genetic variations in response to salinity stress, numerous questions need to be answered to fully understand plant tolerance to salt stress. This chapter provides an overview of previous studies on the genetic control of salinity stress in plants, including signaling, tolerance mechanisms, and the genes, pathways, and epigenetic regulators necessary for plant salinity tolerance

Three different pathway of time perspective toward adolescents’ life satisfaction

Introduction The adolescents can cope life experience from different time perspectives: basing on their negative/positive past and pursuing present gratification or personal future development (Ferrari, et al. 2010; Hesketh, 2000; Peetsma, et al. 2005). According to Zhang, Howell, and Stolarski (2013) and Boniwell and Zimbardo (2004), if adolescents live exclusively in the present they are undermined in their ability to cope with life circumstances, and so they are not likely satisfied with their live (Barcaccia, et al. 2013). Objective The present study examined the cross-sectional relations between three different time perspective (edonistic present, future, and positive past), hedonic balance, hope (agency and pathway) and life satisfaction in adolescence. Method Participants were 702 adolescents (50% males and 50% females) with a mean age of 19,7 years (SD = .78). The measures were all self-report scales and included: Zimbardo Time Perspective Inventory (Zimbardo & Boyd, 1999), PANAS (Watson, Clark, & Tellegen, 1988), The Hope Scale (Snyder, et al., 1991) and Satisfaction with Life Scale (Diener, et al., 1985). A structural equation modeling and mediational analyses were used. Results This study showed that the three different time perspectives marked three different pathway toward the life satisfaction in adolescence. Positive Past predicts directly the life satisfaction; Future predicts indirectly the life satisfaction; Edonistic Present predicts both directly and indirectly (through hedonic balance and hope) the life satisfaction. This model fit the data well, χ2(4) = 26.750, p<.01, CFI = .98, TLI = .91, RMSEA = .08 (.06, .12), SRMR = .03. Conclusions These results evidenced the well-known relationship between time perspective, hedonic balance, hope, and life satisfaction (Sailer, et al. 2014; Drake, et al. 2008; Zhang, Howell, and Stolarski, 2013); however them emphasize the important mediational role played by hope and affectivity on establishing the link between future time perspective and satisfaction with life.
