PURPOSE We investigated reliability, construct validity, and feasibility of two sprint tests for children with cerebral palsy (CP). METHODS Twenty-six children with CP participated (7-18 years of age; Gross Motor Function Classification System [GMFCS] level I or II). On different occasions, the 10 x 5-Meter Sprint Test and the Muscle Power Sprint Test were scored by different assessors. RES...

In this paper we examine sprint-driven software development as it occurs in a specific Open Source community, PyPy. Applying a situated learning perspective, we report the findings from a study focused on the activities leading up to, taking place during, and following after sprints. The study included analyses of sprint reports, email archives and other documents available on the community web...

This investigation describes the sprint performances of the highest internationally ranked professional male road sprint cyclist during the 2008-2011 Grand Tours. Sprint stages were classified as won, lost, or dropped from the front bunch before the sprint. Thirty-one stages were video-analyzed for average speed of the last km, sprint duration, position in the bunch, and number of teammates at ...

this study aimed to assess the effects of four weeks of detraining after eight weeks of intense sprint training on risk factors of atherogenic inflammatory damages. for this purpose, 42 male rats were divided randomly into two groups: sprint training group (experimental) (n=24 and weight 210±7) and control group (n=18 and weight 211±3). the training program was performed for 12 weeks, three ses...

The supernova yields of r-process elements are obtained as a function of the mass of their progenitor stars from the abundance patterns of extremely metalpoor stars on the left-side [Ba/Mg]-[Mg/H] boundary with a procedure proposed by Tsujimoto and Shigeyama. The ejected masses of r-process elements associated with stars of progenitor massMms ≤ 18M⊙ are infertile sources and the SNe II with 20M...

The specific objectives of this study were to determine whether sprint performance in juvenile rainbow trout is correlated with either voluntary swimming activity or aggressive behaviors and to determine the reciprocal: the effect of swimming activity and aggression on sprint performance. Sprint performance was assessed by rapidly accelerating trout (5-7-cm fork length) to a fixed velocity (40,...

PURPOSE This study aimed to determine the pattern of neuromuscular fatigability that manifests during repeated-sprint running exercise. METHODS Twelve male participants (mean ± SD: age, 25 ± 6 yr; stature, 180 ± 7 cm; body mass, 77 ± 7 kg), currently training and competing in intermittent sprint sports, performed a repeated maximal sprint running protocol (12 × 30 m, 30-s rest periods). Pre- ...

Methods Physically active male and female volunteers (n = 13) completed 24 × 50 yard sprints following NEC and DC (counterbalanced). Sprints were completed in 2 halves (12 sprints per half) with 2 minutes recovery between each sprint and a 10-minute recovery period between halves. Acute-RPE (A-RPE) (0–10 omni scale) was recorded after every sprint and Session RPE (S-RPE) was recorded 20 min aft...

The effect of heat acclimatization on aerobic exercise tolerance in the heat and on subsequent sprint exercise performance was investigated. Before (UN) and after (ACC) 8 days of heat acclimatization, 10 male subjects performed a heat-exercise test (HET) consisting of 6 h of intermittent submaximal [50% of the maximal O2 uptake] exercise in the heat (39.7 degrees C dB, 31.0% relative humidity)....

The purpose of this study was to use three-dimensional methods to determine whether there are distinct kinematic differences between sprint and distance front crawl swimmers when swimming at a sprint pace. Seven sprint and eight distance specialists performed four 25-m sprints through a 6.75-m(3) calibrated space recorded by six gen-locked cameras. The variables of interest were: average swim v...
