We employed next-generation, transcriptome-wide RNA sequencing (RNA-Seq) technology to assess the effects of two different exercise training protocols on transcriptional profiles in diaphragm second-order arterioles (D2a) and in the diaphragm feed artery (DFA) from Otsuka Long Evans Tokushima Fatty (OLETF) rats. Arterioles were isolated from the diaphragm of OLETF rats that underwent an enduran...

PURPOSE The purpose of this study was to determine the relationships between split times within sprint tests over 30 m and 40 m in elite Australian Rules footballers. METHODS Data were analyzed from two Australian Football League (AFL) clubs. The first club (n = 35) conducted a 40-m sprint test and recorded split times at 10 m and 20 m. The second club (n = 30) conducted a 30-m sprint test an...

The purpose of the present study was to investigate the bilateral deficit (BLD) in elite sprinters and examine the relationship between the BLD and sprint start performance. Twelve male elite sprinters (age: 22.41±3.39 years, 100m personal best: 10.82±.25s) performed sprint starts, twoand one-leg counter-movement jumps (CMJ). A system of eight CCD cameras with a frequency of 200 Hz was used for...

McBride, JM, Blow, D, Kirby, TJ, Haines, TL, Dayne AM, and Triplett, NT. Relationship between maximal squat strength and five, ten, and forty yard sprint times. J Strength Cond Res 23(6): 1633–1636, 2009—The purpose of this investigation was to examine the relationship between maximal squat strength and sprinting times. Seventeen Division I-AA male football athletes (height = 1.78 6 0.04 m, bod...

Determining which traits enable organisms to colonize and persist in new environments is key to understanding adaptation and ecological speciation. New environments can present novel selective pressures on colonists’ morphology, behaviour, and performance, collectively referred to as ecomorphology. To investigate ecomorphological change during adaptation and incipient ecological speciation, we ...

PURPOSE The aim of this study was to determine the effects of sodium bicarbonate ingestion on prolonged intermittent exercise and performance. METHODS Eight healthy male subjects (mean +/- SD: age 25.4 +/- 6.4 yr, mass 70.9 +/- 5.1 kg, height 179 +/- 7 cm, VO(2max) 4.21 +/- 0.51 L.min-1) volunteered for the study, which had received ethical approval. Subjects undertook two 30-min intermittent...

Objective: To evaluate the effect of hyperventilation during a repeated sprint training on a cycle ergometer. Method: Seven cyclists performed two training sessions (10 maximal sprints of 10 s, with 60 s of rest), one with free ventilatory frequency and another one with hyperventilation (the participants breathed 60 cycles per minute during the last 30 s of recovery). Power, fatigue index and b...

BACKGROUND Cardiovascular morbidity and mortality was reduced by 25% when blood pressure (BP) was targeted to 120 mm Hg systolic compared with 140 mm Hg systolic in Systolic Blood Pressure Intervention Trial (SPRINT); however, BP was measured using a research technique. SPRINT specified 5 minutes of seated rest in a quiet room followed by 3 oscillometric measurements without an observer in the ...
