Predictive modelling of football injuries

arXiv.org Machine Learning

The goal of this thesis is to investigate the potential of predictive modelling for football injuries. This work was conducted in close collaboration with Tottenham Hotspurs FC (THFC), the PGA European tour and the participation of Wolverhampton Wanderers (WW). Three investigations were conducted: 1. Predicting the recovery time of football injuries using the UEFA injury recordings: The UEFA recordings is a common standard for recording injuries in professional football. For this investigation, three datasets of UEFA injury recordings were available. Different machine learning algorithms were used in order to build a predictive model. The performance of the machine learning models is then improved by using feature selection conducted through correlation-based subset feature selection and random forests. 2. Predicting injuries in professional football using exposure records: The relationship between exposure (in training hours and match hours) in professional football athletes and injury incidence was studied. A common problem in football is understanding how the training schedule of an athlete can affect the chance of him getting injured. The task was to predict the number of days a player can train before he gets injured. 3. Predicting intrinsic injury incidence using in-training GPS measurements: A significant percentage of football injuries can be attributed to overtraining and fatigue. GPS data collected during training sessions might provide indicators of fatigue, or might be used to detect very intense training sessions which can lead to overtraining. This research used GPS data gathered during training sessions of the first team of THFC, in order to predict whether an injury would take place during a week.


Women's Sport Week 2017: Gender prize money gap narrowing, new study shows

BBC News

The gender prize money gap in sport is closing with more sports than ever achieving parity at the top level, a BBC Sport study has found. A total of 83% of sports now reward men and women equally, according to the study commissioned for Women's Sport Week. Cricket, golf and football showed some of the biggest disparities although prize money for women has increased substantially in these sports over the past three years. Other sports that do not reward male and female competitors equally according to the study are cliff diving, ski jumping, darts and snooker plus some cycling events. Women are allowed to enter the world championships in darts and snooker but also have their own separate competitions.


Coroner finds no evidence of trauma in Colton sixth-grader who died after school soccer game

Los Angeles Times

A Colton sixth-grader who collapsed during a school soccer game and died Tuesday suffered from an enlarged heart and early signs of congestive heart failure, according to a preliminary coroner's report. The death of 12-year-old Dominick Gallegos stunned classmates at Ulysses S. Grant Elementary School this week, while the boy's parents claimed that a bully had stomped on their son's chest. On Thursday, however, the San Bernardino County Coroner posted a preliminary autopsy that reported no evidence of trauma in the boy's death. "An autopsy was performed on Dominick today," the report stated. "No evidence of trauma was found.



Japan startup's superflies may hold key to food self-sufficiency -- even in space

The Japan Times

Houseflies, the Soviet space program and manned missions to Mars -- these aren't plot devices for a Cold War space thriller, but key terms to understand the history behind Fukuoka-based startup Musca Inc.'s project to provide a solution to some of the world's most pressing agricultural problems: food and animal waste and dwindling supplies of livestock feed. As far-fetched as it may sound, the company's plans for harnessing flies to recycle waste and create natural fertilizer and fish meal has evolved into a small but growing sector in recent years, spawning a crop of insect growers and sparking the interest of global food-production behemoths looking for alternative sources of protein. Fast-food giant McDonald's, for example, is backing studies using insects and algae for chicken feed to reduce reliance on soy and to hold off deforestation. "In terms of variety, we possess G1-level flies," says Ayano Ryugo, the interim chief executive officer of Musca, referring to the term used for horse races featuring the highest caliber thoroughbreds. Ryugo says Musca's technology is based on research that a Japanese man named Kazutoshi Kobayashi purchased from Soviet scientists following the collapse of the USSR.
