OBJECTIVES To evaluate the impact on voice of 2 hours of continuous oral reading. METHODS Fifty normophonic women underwent two sessions of voice loading in which the required intensity level varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. Ten expert judges evaluated the breathiness of one sentence recorded before and after each loading session. Pairs of sti...

Smoking can weaken immune function as reported in previous studies. However, benefits of exercise reducing negative effects smoking on salivary lactoferrin responses is scarce to date. Hence, the purpose this study determine an acute bout among smokers and non-smokers. Eighteen sedentary men were recruited; nine (age = 22.4 ± 1.4 years; BMI 22.1 1.1 kg/m2) non-smokers 0.7 years old; 22.5 1.9 kg...

BACKGROUND The purpose of this study was to assess the repeatability and limits of agreement of corneal thickness values measured by a high-frequency ultrasound (Artemis-2), hand-held ultrasound pachymeter (DGH-500) and a specular microscope (SP-3000P). METHODS Central corneal thickness (CCT) was analyzed in this prospective randomized study that included 32 patients (18 men and 14 women) age...

INTRODUCTION regular exercise has been recommended as an important behavior in controlling blood pressure. In recent years it has been demonstrated that a single session of exercise can lower blood pressure levels compared to pre-exercise period, becoming an effective non-pharmacological therapy for the treatment of hypertension. OBJECTIVE the purpose of this study was to analyze the levels o...

AIM The aim of the present study was to analyze the response of vascular circulating microRNAs (miRNAs; miR-16, miR-21, miR-126) and the VEGF mRNA following an acute bout of HIIT and HVT in children. METHODS Twelve healthy competitive young male cyclists (14.4 ± 0.8 years; 57.9 ± 9.4 ml·min(-1)·kg(-1) peak oxygen uptake) performed one session of high intensity 4 × 4 min intervals (HIIT) at 90...

current research attempted to compare the effect of 10-day oral supplementation with saffron and indomethacin in the prevention of delayed onset muscle soreness (doms). thirty-nine healthy and inactive male students divided into three groups: saffron (300 mg), indomethacin (75 mg), and control groups. muscle soreness protocol performed with 80% of 1rm in four sessions and each session had 20 re...

Humans show implicit memory for complex spatial layouts, which aids in subsequent processing of these layouts. Research efforts in the past 5 years have focused primarily on a single session of training involving a dozen repeated displays. Yet every day, people encounter many more visual layouts than were presented in such experiments. In this study, we trained subjects to learn 60 repeated dis...

BACKGROUND The aim of the present study was to evaluate the acute effects of resistance exercise (RE) leading to failure and RE that was not to failure on 24 h blood pressure (BP) and heart rate variability (HRV) in sedentary normotensive adult women. METHODS Ten women (33.2 ± 5.8 years; 159.3 ± 9.4 cm; 58.0 ±6.4 kg; body fat 28.4 ± 2.8%) randomly underwent three experimental sessions: contro...

It is unclear how athletes regulate their performance prior and during exercise when deceptive methods are applied. Therefore, the aim of this study was to test if time manipulation can influence pacing strategy running performance. Ten recreationally active subjects were informed they would complete four 60-min trials only with feedback. The first session a familiarization trial (60-min), in f...
