Impart backspin and pitch the ball up: strategies cricket fast bowlers can employ to generate late swing.

In cricket fast bowling, late swing can increase interception difficulty for opposition batters. However, little is known about the occurrence and cause of late swing. This study investigated ball kinematics and the effect of changing kinematics on late swing with new cricket balls.

The repeatability of stride time variability, regularity, and long-range correlations.

Background: Detrended fluctuation analysis (DFA) and sample entropy (SE) measure the long-term correlations and regularity of gait patterns, respectively, having previously been used to identify participants at risk of falling, previous history of injury, or patients with motor diseases. Since these measures are more sensitive to gait impairment than linear measures (e.g.

The effect of weapon handling during load carriage across a range of military-relevant walking speeds.

This study investigated the effects of weapon handling on the physiological responses and walking-gait kinematics during load carriage. Seventeen soldiers completed four twelve-minute bouts of treadmill walking at incremental speeds (3.5, 5.

The use of small-arms stability measures in combat shooting assessments.

The acquisition of weapons at scale requires objective measures to discriminate between products and inform decisions. Testing of weapons commonly occurs on known-distance ranges in static positions at static targets using accuracy and timing as the main variables of interest. However, testing weapons in more representative environments may better show variations in ergonomic-related factors such as centre-of-gravity (CoG) changes.

Nasal sprays and behavioural interventions compared with usual care for acute respiratory illness in primary care: a randomised, controlled, open-label, parallel-group trial.

Background: A small amount of evidence suggests that nasal sprays, or physical activity and stress management, could shorten the duration of respiratory infections. This study aimed to assess the effect of nasal sprays or a behavioural intervention promoting physical activity and stress management on respiratory illnesses, compared with usual care.

Methods: This randomised, controlled, open-label, parallel-group trial was done at 332 general practitioner practices in the UK.
