Research has suggested that caffeine enhances aerobic performance. The evidence for high-intensity, short-term exercise, particularly resistance exercise is mixed and has not fully examined the psychological changes that occur after this mode of exercise with caffeine ingestion. This study examined the effect of caffeine (5 mg · kg(-1)) vs. placebo on bench press exercise to failure and the moo...

BACKGROUND Resistance training has been introduced in cardiac rehabilitation to give more benefit than traditional training. Haemodynamic evaluation of cardiac patients to resistance training has generally consisted of continuous HR monitoring and discontinuous blood pressure measurements. DESIGN AND METHODS Blood pressure (BP) and heart rate (HR) responses to resistance training were evaluat...

Introduction: Thermography records the skin temperature, which can be influenced by: muscle mass and subcutaneous fat layer. Thus, the aim of this study was to investigate the influence of subcutaneous fat layer in the skin temperature variation rate, during exercise. Methods: This is a short-longitudinal study that involved 17 healthy male trained volunteers. Volunteers were divided in two gro...

We have demonstrated a quantum cascade laser (QCL) with generation frequency of about 3.8 THz, grown by metal-organic vapor phase epitaxy. The multilayer heterostructure for QCLs consists 185 repetitions an active module containing four GaAs/Al0.15Ga0.85As wells. threshold current and voltage the fabricated QCL were 2.25 kA/cm2 19.7 V, respectively. was generated in multimode regime, detection ...

Repetition is one of the most striking features Émile Zola's prose style. It was also frequently commented-upon, and criticized, aspects his writing among contemporaneous critics. This article reads critical responses to repetitions, as well own comments on matters style, for what they can reveal about assumptions at work in fin-de-siècle literary criticism's conception craft. suggests that hos...
