Reliability and validity of the fulltrack AI application to determine cricket bowling line and length compared to 3D motion capture.

This study examined reliability and validity of the application to identify cricket ball landing position (line, length). Nine hundred and thirty-two deliveries were compared to 3D motion capture, the criterion measure, with 836 included in analysis (516 bowled (pace = 420, spin = 96), 320 Sidearm; 301 facing a batter). Agreement analysis indicated an intraclass correlation coefficient of >0.

A Radiographic Technique for Assessment of Morphologic Variations of the Equine Caudal Cervical Spine.

Equine Caudal Cervical Morphologic Variation (ECCMV) is a congenital malformation of the caudal cervical spine distinct from the more commonly recognized Cervical Vertebral Stenotic Myelopathy (CVSM). The most common presentation of ECCMV is recognized on the sixth cervical vertebra (C6). In "normal" presentations, the transverse processes on the left and right sides have a caudal lamina projecting ventrally below the caudal vertebral body in a heel shape.

Ground force kinetic adaptations associated with canine boots.

Introduction: Dog boots are being utilized to improve performance and welfare of dogs exposed to a range of adverse conditions; however, there is a lack of empirical evidence establishing the impact of these on gait characteristics. The aim of this research was to quantify alterations to ground force kinetics associated with the introduction of canine boots.

Methods: Six clinically sound beagles were analyzed on two separate occasions using a cross-over study design to enable randomization between barefoot and shod conditions.

Changes in Unilateral Upper Limb Muscular Strength and Electromyographic Activity After a 16-Week Strength Training Intervention in Survivors of Breast Cancer.

Hagstrom, AD, Shorter, KA, and Marshall, PWM. Changes in unilateral upper limb muscular strength and Electroymographic activity after a 16-week strength training intervention in survivors of breast cancer. J Strength Cond Res 33(1): 225-233, 2019-Upper limb strength deficits are frequently observed following breast cancer (BC) and its treatments.

Creatine kinase, neuromuscular fatigue, and the contact codes of football: A systematic review and meta-analysis of pre- and post-match differences.

Physiological or performance tests are routinely utilised to assess athletes' recovery. At present, the ideal tool to assess recovery remains unknown. Therefore, the aim of this systematic review was to examine the change in creatine kinase (CK) and neuromuscular function as measured via a countermovement jump (CMJ) following a match in the contact codes of football.

Modelling Movement Energetics Using Global Positioning System Devices in Contact Team Sports: Limitations and Solutions.

Quantifying the training and competition loads of players in contact team sports can be performed in a variety of ways, including kinematic, perceptual, heart rate or biochemical monitoring methods. Whilst these approaches provide data relevant for team sports practitioners and athletes, their application to a contact team sport setting can sometimes be challenging or illogical. Furthermore, these methods can generate large fragmented datasets, do not provide a single global measure of training load and cannot adequately quantify all key elements of performance in contact team sports.

A Novel Non-Invasive Selection Criterion for the Preservation of Primitive Dutch Konik Horses.

The Dutch Konik is valued from a genetic conservation perspective and also for its role in preservation of natural landscapes. The primary management objective for the captive breeding of this primitive horse is to maintain its genetic purity, whilst also maintaining the nature reserves on which they graze. Breeding selection has traditionally been based on phenotypic characteristics consistent with the breed description, and the selection of animals for removal from the breeding program is problematic at times due to high uniformity within the breed, particularly in height at the wither, colour (mouse to grey dun) and presence of primitive markings.

Energetic Demands of Interchange and Full-Match Rugby League Players.

Cummins, CJ, Gray, AJ, Shorter, KA, Halaki, M, and Orr, R. Energetic demands of interchange and full-match rugby league players. J Strength Cond Res 32(12): 3456-3464, 2018-The purpose of this study was to describe and compare the metabolic demands of rugby league for interchange and full-match players in relation to positional groups.

Running-Intensity Fluctuations in Elite Rugby Sevens Performance.

Purpose: To investigate temporal variation in running intensity across and within halves and evaluate the agreement between match-analysis indices used to identify fluctuations in running intensity in rugby sevens.

Methods: Data from a 15-Hz global positioning system (GPS) were collected from 12 elite rugby sevens players during the IRB World Sevens Series (N = 21 full games). Kinematic (eg, relative distance [RD]) and energetic (eg, metabolic power [MP]) match-analysis indices were determined from velocity-time curves and used to investigate between-halves variations.

A comparison of ballistic and nonballistic lower-body resistance exercise and the methods used to identify their positive lifting phases.

This study compared differences between ballistic jump squat (B) and nonballistic back squat (NB) force, velocity, power, and relative acceleration duration, and the effect that the method used to identify the positive lifting phase had on these parameters. Ground reaction force and barbell kinematics were recorded from 30 resistance trained men during B and NB performance with 45% 1RM. Force, velocity, and power was averaged over positive lifting phases identified using the traditional peak barbell displacement (PD) and positive impulse method.
