Direct-To-Consumer Genetic Testing For Predicting Sports Performance And Talent Identification: Consensus Statement., Nick Webborn, Alun Williams, Mike Mcnamee, Claude Bouchard, Yannis Pitsiladis, Ildus Ahmetov, Euan Ashley, Nuala Byrne, Silvia Camporesi, Malcolm Collins, Paul Dijkstra, Nir Eynon, Noryuki Fuku, Fleur Garton, Nils Noppe, Soren Holm, Jane Kaye, Vassilis Klissouras, Alejandro Lucia, Kamiel Maase, Colin Moran, Kathryn North, Fabio Pigozzi, Guan Wang

Nuala Byrne

The general consensus among sport and exercise genetics researchers is that genetic tests have no role to play in talent identification or the individualised prescription of training to maximise performance. Despite the lack of evidence, recent years have witnessed the rise of an emerging market of direct-to-consumer marketing (DTC) tests that claim to be able to identify children's athletic talents. Targeted consumers include mainly coaches and parents. There is concern among the scientific community that the current level of knowledge is being misrepresented for commercial purposes. There remains a lack of universally accepted guidelines and legislation for DTC testing in …

Soldier Occupational Load Carriage – A Narrative Review Of Associated Injuries, Robin Orr, Rodney Pope, Venerina Johnston, Julia Coyle

Rodney P Pope

This narrative review examines injuries sustained by soldiers undertaking occupational load carriage tasks. Military soldiers are required to carry increasingly heavier occupational loads. These loads have been found to increase the physiological cost to the soldier and alter their gait mechanics. Aggregated research findings suggest that the lower limbs are the most frequent anatomical site of injury associated with load carriage. While foot blisters are common, other prevalent lower limb injuries include stress fractures, knee and foot pain, and neuropathies, like digitalgia and meralgia. Shoulder neuropathies (brachial plexus palsy) and lower back injuries are not uncommon. Soldier occupational load carriage …
