47 Using next generation, transcriptome-wide, RNA sequencing (RNA-Seq) technology we 48 assessed the effects of exercise training on transcriptional profiles in skeletal muscle arterioles 49 isolated from the soleus and gastrocnemius muscles of Otsuka Long Evans Tokushima Fatty 50 (OLETF) rats that underwent an endurance exercise training program (EX; n=13), interval sprint 51 training program ...

The purpose of the study was to examine the relationships among aerobic fitness, anaerobic capacity, and performance indices of 2 different repeated sprint test (RST) protocols in a group of 33 elite adolescent soccer players (age range 16-18 years). All participants performed 4 tests: an aerobic power test (20-m shuttle run), the Wingate Anaerobic Test (WAnT), and 2 different RST protocols (12...

Postactivation potentiation (PAP), an acute and temporary enhancement of muscular performance resulting from previous muscular contraction, commonly occurs after heavy resistance exercise. However, this method of inducing PAP has limited application to the precompetition practices (e.g., warm-up) of many athletes. Very few studies have examined the influence of plyometric activity on subsequent...

PURPOSE Two studies involving 122 handball players were conducted to assess the reliability, usefulness, and validity of a repeated shuttle-sprint and jump ability (RSSJA) test. The test consisted of 6x(2x12.5-m) sprints departing on 25 s, with a countermovement jump performed during recovery between sprints. METHODS For the reliability and usefulness study, 14 well-trained male handball play...

The blood lactate concentration is generally considered an indicator for evaluating anaerobic work capacity in man. It has been reported that the peak blood lactate concentration measured after supramaximal exercise lasting for about 1 min highly correlated with running time for the 400-m sprint in untrained subjects and long-distance runners (FUJITSUKA et al., 1982; OIKUWA et al., 1984a). We o...

The aim of this study was to investigate the changes in the relationships between repeated sprint ability (RSA) and anthropometric measures as well as fitness qualities in soccer players. Twenty-one professional soccer players performed several anthropometric and physical tests including countermovement vertical jumps (CMJs), a straight-line 30 m sprint (T30), an RSA test (6 x 20 + 20 m with 20...
