Design of a Wireless Wereable DAQ System for the Evaluation of Sports Performances

An accurate monitoring of the professional athletes\u2019 exercises during training sessions is able to improve their performance by helping them in improving the effectiveness of the movement, in the injury prevention and in the rehabilitation protocols. Wearable and non-encumbrance DAQ (Digital Acquisition) systems are required because it is important to collect data from the athlete\u2019s performance in his natural environment rather than in the unspecific spaces of a laboratory. This paper deals with the design of a wireless data logger for the evaluation and analysis of the sport performance. In particular, the system is composed of a multichannel sEMG (surface Electromyography) system synchronized the kinematic signals obtained by an Inertial Measurement Unit (IMU) placed on the back of the athlete by the use of a belt. The system can be wirelessly connected with a proper terminal for data display and analysis

Technical skill differences in stroke propulsion between high level athletes in triathlon and top level swimmers

In the latest decades the arm propulsion mechanism in human swimming has been an issue of great interest for researchers. The availability of new devices which can easily measure the stroke propulsion by means of a non invasive gauge allows the study of technical skills in real swimming, without artificial and distorting conditions like in a swimming flume or in tethered swimming. Performance in swimming is a crucial factor in another sport such as Olympic Triathlon, however we saw that the triathlon athletes presented shortfalls and differences with respect to expert swimmer, particularly in mean pressure and resultant momentum, but not maximum pressure. Each athlete showed a distinctive shape of the pressure curve, but triathletes present a greater variability in the pressure pattern than competitive swimmers, as is the case of novice vs. expert swimmers observed in previous studies. The possibility of pointing out some differences in stroke propulsion between top level swimmers and high level athletes in triathlon could give some useful indications for coaches in planning triathlon training
