Determining a Relationship Between Posterior Chain Flexibility and Linear Sprint Speed
… flexibility using the sit-and-reach test and speed in the 40-yard dash. All test subjects were male between the ages of 18-22, and members of a Division I university football team. All 95 test subjects had participated in at least one semester of a strength and conditioning program designed by …

Effects of Temperature on Foraging, Endurance, and Sprint Speed in Agkistrodon Piscivorus and Nerodia Sipedon
… performance at 10, 20 and 30°;C, and found that sprint speed and endurance increase with temperature in both species. All snakes swam faster than they crawled in sprint trials and thermal effects on endurance were more apparent in aquatic than terrestrial conditions. Water snakes were faster and …

A Series of Studies Examining the Development of Sprint Speed and Momentum of International Rugby Union Players
Sprinting speed is a highly valued physical ability in rugby. There is little research examining sprinting biomechanics in rugby players and it is unclear the extent that sprinting speed and sprint momentum can even be improved in highly trained rugby players and how different speed and strength …

The Effects Of Depth Jump Implementation Of Sprint Performance In Collegiate And Club Sport Athletes
… strength and power have a transfer effect to sprint speed; however, few have examined if implementing DJs into training can increase sprint speed. Purpose; The purpose of this study was to determine if the implementation of DJs into a sprint training program would increase sprint speed more so …

Home Field Advantage: Sprint Sensitivity to Ecologically Relevant Substrates in Lizards
… in an attempt to link ecology and morphology. Sprint sensitivity is the decrease in sprint speed due to change in substrate. This study measures sprint sensitivity to substrate rugosity among six lizard species that occupy rocky, sandy, and/or semi-arboreal habitats. Lizards that use rocky …

The Effects of Locomotor Posture on Kinematics, Performance and Behavior during Obstacle Negotiation in Lizards
… body forms and ecology. I also examined how sprint speed changed when crossing obstacles with a quadrupedal versus a bipedal posture. I quantified kinematics from high-speed video (300 frames/second) of lizards running down a 3m runway both with and without the presence of an obstacle. Among …

Influence of Diet on Growth and Health of Captive Hatchling Gopher Tortoises (Gopherus polyphemus)
… hatchling tortoises, we compared growth rates, sprint speeds, and blood chemistry parameters of gopher tortoise hatchlings reared on four different diets over a period of 168 days. Tortoises fed Mazuri brand tortoise diet or a mixture of horse feed and vegetables had significantly higher growth …

The effect of a 4-week sprint training program on sprint ability of female soccer players: a single-subject research design
… modern soccer has led to an increased number of sprints a player performs, and the total sprint distance he covers during a game. Therefore, a greater emphasis should be placed on improving sprint ability than before. Objectives: 1. To develop a sprint training program for soccer players, A) …

Genotypic and Phenotypic Variation of the Florida Scrub Lizard (Sceloporus Woodi)
… of the Florida scrub lizard by examining sprinting and jumping ability. These are key performance measures that have been widely studied in vertebrates. The vast majority of these studies, however, use methodologies that lack ecological context by failing to consider the complex habitats …

Phenotypic Responses to Invasion in the Brown Anole (Anolis sagrei)
… lower temperatures, exhibited greater maximum sprint speeds, and had higher metabolic rates than native populations. Next, I examined how life-history traits may change in the invasive range in order to facilitate reproduction under shorter breeding and growing seasons. I found that compared to …

Unlocking the Potential: Exploring the Impact of Generative Artificial Intelligence in Agile Software Engineering
… redundant work and accelerate Agile processes. Sprint speed improvements (β = 0.39, p < 0.001) further optimizes efficiency. While organizational AI support fosters transformation, its direct effect on efficiency is less pronounced (β = 0.079, p = 0.294), suggesting that success depends on …

Effects of deep-water running and land-based running program on aerobic power, physical fitness and motivation on female youth footballers
… jumping height, kicking velocity, agility, sprint speed, intrinsic motivation, extrinsic motivation, and amotivation. The intervention took seven weeks, with two-to-three endurance session per week, per group at the start of the pre-season in January 2018. The intensity was matched with …

The effectiveness of resistance, plyometric and sprint training at different stages of maturation in male youth athletes
… of physical capacities such as movement speed, strength and power is difficult to predict in youth meaning that the structuring of training can be a significant challenge for coaches. Accordingly, methodologically sound research is required to underpin a more informed approach to the …

The role of lactate supplementation and metabolism in invasion sport performance
… rugby union match play to determine whether sprint speed and intermittent sprint performance could be improved. Ten recreationally active participants were recruited for part one of the study to determine the rate at which orally consumed lactate solution appears in the blood. For part two of …

An Australian perspective on talent identification and development in soccer
… assessments (lower body muscular power, linear speed, change of direction skill, and intermittent aerobic endurance), along with a participation history questionnaire (start age in competitive soccer, total volume of soccer-specific practice, total volume of peer-led play, number of other …

Acute Effects of Whole-Body Vibration on 30 Meter Fly Sprint Performance in NCAA Division I Sprinters and Jumpers.
… a potentiation effect on 30 meter (m) fly sprint performance in collegiate sprinters and jumpers (M=21, W=5) following an acute bout of whole-body vibration. The WBV protocol consisted of one 30 second bout at 50 Hz, ~3 mm amplitude, and 60 seconds rest before a 30m fly sprint. Sprint times …

A unique specific jumping test to estmate explosive power for basketball players: validity, reliability and differences in age, gender and playing position
… tools relevant to the game: 5-meter and 10-meter sprint speed tests; standing broad jump assessment; horizontal and vertical drop jump tests; 2x5-meter change of direction ability test; countermovement jump test; squat jump test; bounding power test; and spike jump test. As some of these tests …

The Interrelationships of Fitness Characteristics in Division 1 Athletes
… power, vertical jump height, shortdistance sprinting ability, muscularity, and body fat percentage. These variables have been shown in previous research to independently affect athletic performance outcomes, but their relationships to one another are less clear. Eighty Division I athletes …

The epidemiology of injuries in elite soccer and the impact of injury-induced detraining on physiological performance
… differences in tests to evaluate flying 20 m sprint speed, counter-movement jump height and hamstring flexibility. Significant decreases in performance were however, found in estimated V? O?max, and repeated sprint ability (RSA) performance. It was suggested that the decrements in aerobic …

The application of maximal mean and critical speed and metabolic powers for the quantification of external load in soccer
… more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to determine individual work capacities. …
