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...

The aim of this study was to identify the dry land strength and power tests that can better relate with sprint swimming performance in young competitive swimmers. Twenty-eight (16 boys and 12 girls) young competitive swimmers of national level (12.01 ± 0.56 years-old, Tanner stage 1-2) volunteered to participate in this study. Swimming performance (25 m and 50 m freestyle sprint tests), muscle ...

Although of prime ecological relevance, acceleration capacity is a poorly understood locomotor performance trait in terrestrial vertebrates. No empirical data exist on which design characteristics determine acceleration capacity among species and whether these design traits influence other aspects of locomotor performance. In this study we explore how acceleration capacity and sprint speed have...

The aim of this study was to examine the relationship between short sprint time (5 m) and strength metrics of the countermovement jump (CMJ) using a linear transducer in a group of trained athletes. Twenty-five male, trained subjects volunteered to participate in the study. Each volunteer performed 3 maximal CMJ trials on a Smith machine. Peak instantaneous power was calculated by the product o...
