BACKGROUND Adults <50 years old, with diabetes mellitus, or a history of stroke were not enrolled in the Systolic Blood Pressure Intervention Trial (SPRINT). Estimating the size and characteristics of these excluded groups who meet the other SPRINT eligibility criteria may provide information on the potential impact of providers extending the SPRINT findings to these populations. METHODS AND ...

We quantified four gait characteristics (stride length, stride frequency, step length and floating distance) over a range of running speeds in 11 lacertid lizard species known to vary in maximal sprint speed and microhabitat use. For each species, we measured snout-vent length (SVL), body mass and hindlimb length. We tested which variables determine sprint speed, how each species modulates spri...

The relationships between 30m sprint time and performance on a non-motorized treadmill test, as well as a vertical jump test were determined in the present investigation. Seventy-eight physically active men and women (22.9±2.7 y; 73.0±14.7 kg; 170.7±10.4 cm) performed a 30-s maximal sprint on the Curve™ non-motorized treadmill (TM) following one familiarization trial. Pearson product-moment cor...

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (...

PURPOSE The anticipation of exercise-induced stress influences performance during continuous exercise. However, not all exercise is continuous. This study explores the influence of prior knowledge of sprint number on mechanical work, surface EMG, and RPE during repeated-sprint exercise (RSE). METHODS Fourteen athletes performed three RSE in random order. In one trial, subjects were informed t...

Vibration exercise (VbX) has been a popular modality to enhancing physical performance, where various training methods and techniques have been employed to improve immediate and long-term sprint performance. However, the use of acute side-alternating VbX on sprint and agility performance remains unclear. Eight female athletes preformed side-alternating vibration exercise (VbX) and control (no V...

The purpose of this study was to examine gender differences in repeated sprint exercise (RSE) performance among male and female athletes matched for VO2max relative to FFM (VO2max FFM). Thirty nine male and female college athletes performed a graded exercise test for VO2max and hydrostatic weighing to determine FFM. From the results, 11 pairs of males and females matched for VO2max FFM (mean ± ...

We investigated how substrate diameter affects acceleration performance in three Anolis lizard species (A. sagrei, A. carolinensis and A. valencienni), representing three different ecomorphs (trunk-ground, trunk-crown, and twig, respectively). We did so by measuring maximal acceleration capacity of the three species on a broad and narrow dowel. In addition to acceleration capacity, we quantifie...

the purpose of this study was to determine the effect of interval sprint exercise and a detraining period on lipid peroxidation (mda) and the response of antioxidant system (frap, uric acid, bilirubin and total protein). for this purpose, 35 male rats were divided randomly into two groups: sprint group (experimental) (n=20) and control group (n=15, without any training). experimental group trai...
