The growth of sport science technology is enabling more sporting teams to implement athlete monitoring practices related to performance testing and load monitoring. Despite the increased emphasis on youth athlete development, the lack of longitudinal athlete monitoring literature in youth athletes is concerning, especially for indoor sports such as basketball. The aim of this study was to evaluate the effectiveness of six different athlete monitoring methods over 10 weeks of youth basketball training. Fourteen state-level youth basketball players (5 males and 9 females; 15.1 ± 1.0 years) completed this study during their pre-competition phase prior to their national basketball tournament. Daily wellness and activity surveys were completed using the OwnUrGoal mobile application, along with heart rate (HR) and inertial measurement unit (IMU) recordings at each state training session, and weekly performance testing (3x countermovement jumps [CMJs], and 3x isometric mid-thigh pulls [IMTPs]). All of the athlete monitoring methods demonstrated the coaching staff's training intent to maintain performance and avoid spikes in workload. Monitoring IMU data combined with PlayerLoad™ data analysis demonstrated more effectiveness for monitoring accumulated load (AL) compared to HR analysis. All six methods of athlete monitoring detected similar trends for all sessions despite small-trivial correlations between each method (Pearson's correlation: −0.24 < r < 0.28). The use of subjective monitoring questionnaire applications, such as OwnUrGoal, is recommended for youth sporting clubs, given its practicability and low-cost. Regular athlete education from coaches and support staff regarding the use of these questionnaires is required to gain the best data.

An up-to-date review of the scale of the electronic waste problem, the impact of recent legislation, current and future methods for treatment, recycling and disposal, Electronic waste includes such items as TVs, computers, LCD and plasma displays, and mobile phones, as well as a wide range of household, medical and industrial equipment which are simply discarded as new technologies become available. Huge and growing quantities of waste are discarded every year and this waste contains toxic and carcinogenic compounds which can pose a risk to the environment. However, if handled correctly, electronic waste presents a valuable source of secondary raw materials. This book brings together a group of leading experts in the management of electrical and electronic waste to provide an up-to-date review of the scale of the waste problem, the impact of recent legislation such as the Waste Electrical and Electronic Equipment Directive (WEEE) and the "restriction of the use of certain hazardous substances in electrical and electronic equipment" directive (RoHS), and of current and future methods for treatment, recycling and disposal of this waste. The book discusses these latest directives, examines current worldwide legislation and considers the opportunities and threats posed by this form of waste. While the emphasis is on European practice, comparisons with other countries such as the USA, Japan and China are made. The book deals with the full range of waste management issues, including recycling and recovery of materials, design considerations for waste minimisation, and contains a wide variety of illustrative case studies eg: LCD displays. With detailed and comprehensive coverage of the subject matter it also contains an extensive bibliography with each chapter. Key chapters cover areas such as: -electronic waste -materials -EU directives -landfill and incineration -recycling and recovery -'cradle to grave' design considerations -engineering thermoplastics It is essential reading for all involved with electrical and electronic waste management through its comprehensive review of recent EU legislation and the subsequent impact on manufacturers and users of electronic equipment
