The impact of manipulating shear stress on conduit artery vasodilation has not been comprehensively described in vivo. We hypothesized that manipulation of SR through the brachial and radial arteries would be associated with corresponding changes in diameter. We performed a series of studies involving the following: (1) leg cycle exercise at increasing intensities (≈70 and 85% maximum heart rat...

Aim of the study was to examine cardiorespiratory parameters at individual ventilatory threshold (IVT) and peak exercise capacity ([Formula: see text]) in outpatient diabetic and sarcopenic obese subjects. Seventeen obese subjects (BMI: 36.6 ± 4.1 kg·m(-1)) and sixteen SO subjects (BMI: 37.0 ± 7.3 kg·m(-1)) were compared with sixteen T2DM subjects (BMI: 37.7 ± 5.6 kg·m(-1)). All groups performe...

Heart rate (HR) is arguably one of the most often measured physiological responses in relation to physical fitness or health. HR measured at rest, during submaximal exercise, at maximal exercise and during recovery can provide some level of assessment of fitness and health. In the past, HR was most often measured from manual palpitation of a pulse (palpation), using a stethoscope (auscultation)...

To compare the effects of 6 weeks of long or short high-intensity interval training (long- or short-HIIT) on body composition, hunger perception, food intake and rating of perceived exertion (RPE). Twenty previously untrained women (25±5 years) were randomly assigned to do a long-HIIT (n=10) or a short-HIIT (n=10). The long-HIIT group performed fifteen 1-min bouts at 90% of maximum heart rate (...

Low-volume, time-efficient high-intensity interval training (HIIT), which involves whole-body (WB) callisthenics exercises, has gained worldwide popularity in recent years. However, the physiological and perceptual impact of WB-HIIT comparison to specialised, equipment-based is relatively less studied. This study compared acute responses a single session WB-HIIT, ergometer-based HIIT (ERG-HIIT)...

PURPOSE The aim of the present study was to investigate effects of low cadence training at moderate intensity on aerobic capacity, cycling performance, gross efficiency, freely chosen cadence, and leg strength in veteran cyclists. METHOD Twenty-two well trained veteran cyclists [age: 47 ± 6 years, maximal oxygen consumption (VO2max): 57.9 ± 3.7 ml · kg(-1) · min(-1)] were randomized into two ...

This study aimed to prove the effect of moderate-intensity aerobic exercise on increasing Peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1α) levels in obese women. A total 12 women aged 20-25, with body mass index (BMI) 25-30 kg/m2, normal systolic blood pressure, and resting heart rate as subjects study. Subjects were randomly divided into 2 groups, namely K1 (n=6; co...

The purpose of this study was to examine the influence of different team formation methods on the physiological responses to and time-motion characteristics of 4-a-side small-sided games (SSG4) in young soccer players. Thirty-two young soccer players (age 16.2 ± 0.7 years; height 172.9 ± 6.1 cm; body mass 64.1 ± 7.7 kg) voluntarily participated in this study. Anthropometric measurements, techni...

This study aimed to assess the external and internal loads of Brazilian soccer referees during official matches. A total of 11 field referees (aged 36.2 ± 7.5 years) were monitored during 35 matches. The external (distance covered, mean and maximal speed) and internal load parameters (session ratings of perceived exertion [RPE] training load [TL], Edwards' TL, and time spent in different heart ...
