Effect of warm-up protocols using lower and higher loads on multiple-set back squat volume-load.

Background: The present study aimed to investigate the effects of post-activation performance enhancement (PAPE) after three warm-up protocols on back squat performance in trained men.

Methods: Fourteen resistance-trained men performed conditioning activity (CA) with high-load (HL-CA), low-load (LL-CA), or usual specific warm-up as a control (CON). HL-CA consisted of one set of three repetitions with 90% of one repetition maximum (RM); LL-CA consisted of one set of six repetitions with 45% of 1 RM performed at maximal velocity; CON involved eight repetitions with 45% of 1 RM at controlled velocity.

Acute and Chronic Effects of Interval Training on the Immune System: A Systematic Review with Meta-Analysis.

Purpose: To summarize the evidence regarding the acute and chronic effects of interval training (IT) in the immune system through a systematic review with meta-analysis.

Design: Systematic review with meta-analysis.

Data Source: English, Portuguese and Spanish languages search of the electronic databases Pubmed/Medline, Scopus, and SciELO.

[Formula: see text] Neuropsychological functioning and its relationship with brain anatomical measures of children and adolescents with non-syndromic cleft lip and palate.

Children and adolescents with non-syndromic cleft lip and palate (NSCLP) show cognitive performance below expected. This difficulty can be associated with alterations in the cortical thickness and volume of brain regions. The aim of this study was to investigate anatomical brain characteristics and their relationship with the neuropsychological scores of children and adolescents with NSCLP.

Acute effects of different resistance training loads on cardiac autonomic modulation in hypertensive postmenopausal women.

Background: Individuals with arterial hypertension often have an autonomic nervous system (ANS) imbalance with predominance of sympathetic ANS. This predominance can lead to injury of several organs affecting its functioning. There is evidence that performing high intensity resistance training (RT) with heavier loads and a lower number of repetitions results in lower cardiovascular stress when compared with lighter loads and a higher number of repetitions.

Effect of nitrous oxide on fentanyl consumption in burned patients undergoing dressing change.

Background And Objectives: Thermal injuries and injured areas management are important causes of pain in burned patients, requiring that these patients are constantly undergoing general anesthesia for dressing change. Nitrous oxide (N2O) has analgesic and sedative properties; it is easy to use and widely available. Thus, the aim of this study was to evaluate the analgesic effect of N2O combined with fentanyl in burned patients during dressing change.
