Auto detecting deliveries in elite cricket fast bowlers using microsensors and machine learning.

Cricket fast bowlers are at a high risk of injury occurrence, which has previously been shown to be correlated to bowling workloads. This study aimed to develop and test an algorithm that can automatically, reliably and accurately detect bowling deliveries. Inertial sensor data from a Catapult OptimEye S5 wearable device was collected from both national and international level fast bowlers (n = 35) in both training and matches, at various intensities.

The Response to and Recovery From Maximum-Strength and -Power Training in Elite Track and Field Athletes.

Unlabelled: There is a great deal of research on the responses to resistance training; however, information on the responses to strength and power training conducted by elite strength and power athletes is sparse.

Purpose: To establish the acute and 24-h neuromuscular and kinematic responses to Olympic-style barbell strength and power exercise in elite athletes.

Methods: Ten elite track and field athletes completed a series of 3 back-squat exercises each consisting of 4 × 5 repetitions.

Reliability of a combined biomechanical and surface electromyographical analysis system during dynamic barbell squat exercise.

An analysis system for barbell weightlifting exercises is proposed to record reliable performance and neuromuscular responses. The system consists of surface electromyography (sEMG) synchronized with electrogoniometry and a barbell position transducer. The purpose of this study was to establish the reliability of the three components of the system.
