The objective of the study was to investigate the influence of serial administration of a carbohydrate (CHO) mouth rinse on performance, metabolic and perceptual responses during a cycle sprint. Twelve physically active males (mean (± SD) age: 23.1 (3.0) years, height: 1.83 (0.07) m, body mass (BM): 86.3 (13.5) kg) completed the following mouth rinse trials in a randomized, counterbalanced, dou...

BACKGROUND Repeated-sprint training in hypoxia (RSH) is a recent intervention regarding which numerous studies have reported effects on sea-level physical performance outcomes that are debated. No previous study has performed a meta-analysis of the effects of RSH. OBJECTIVE We systematically reviewed the literature and meta-analyzed the effects of RSH versus repeated-sprint training in normox...

A hypertrophy of psoas muscle (PM) is assigned to be one of the major determinants for sprint running [2]. Moreover, the erector spinae and quadratus lumborum muscles related to the sprint performance [3]. These results suggest that higher sprint performance require the stabilization of the trunk lateral movement. The main function of PM is to flex the thigh on the pelvis, but also counteract a...

PURPOSE OF REVIEW The optimal blood pressure (BP) goal during treatment of hypertension has been controversial. In this report, recent articles that elaborate on this issue are reviewed. RECENT FINDINGS Results from the Systolic Blood Pressure Intervention Trial (SPRINT) have suggested substantial benefits from more intensive BP lowering than is recommended in current US BP management guideli...

The primary purpose of this paper was to provide insight into the methodological issues and associated reliability of assessments used to quantify running sprint ability in youth athletes aged 8-18 years. Over-ground sprinting was the most reliable and common used choice of assessment to measure sprint performance of youth. In addition, the performance data of those athletes over distances rang...

Systolic Blood Pressure Intervention Trial (SPRINT) was a multicenter randomized controlled trial showing the significant benefit of intensive reduction of blood pressure to a target of 120 mm Hg in individuals with hypertension and elevated cardiovascular risk. Because SPRINT includes the largest cohort of adults with chronic kidney disease (CKD) to be prospectively studied in a hypertension i...

The purpose of this study was to determine indices of swimming repeated sprint ability (RSA) in 19 elite water polo players compared to 16 elite swimmers during a repeated sprint swimming test (RST), and to examine the relationships between these indices and aerobic and anaerobic performance capabilities in both groups. Indices of RSA were determined by the ideal sprint time (IS), the total spr...

The study examined the (1) interrelation of cognitive-athletic performance concerning game time and (2) injuries; (3) relation between executive functions intelligence. A total 172 elite soccer players (age: 12–34 years) performed tests assessing multiple-object-tracking, working memory capacity (WMC), cognitive flexibility (CF), inhibition. General specific-endurance-performance, physical (jum...

The aim was to investigate the effect of a dietary supplementation on the repeated sprint ability (RSA) performance in recreationally trained team sports athletes. Twelve young men underwent a RSA exercise protocol in five trials, in which participants ingested carbohydrates (CHO) plus caffeine (Caf), CHO plus arginine (Arg), CHO plus branched-chain amino acids (BCAA), CHO plus Caf, Arg, and BC...

talent identification is a process through which those with the highest chance to succeed in the future will be determined. the purpose of the present study was to investigate the application of a multivariate approach in talent identification of adolescent soccer players. the research population consisted of all soccer players in tehran province aged between 12 and 16 years old. a battery of t...
