Propulsion power is an important metric in wheelchair racing. For a flat surface, it can be estimated from the sum of friction power and kinetic power. Usually, to determine friction power, the rolling and air drag coefficient first need to be determined with coast-down tests or other time-consuming methods. The aim of this paper was to...

Insight into in-field mechanical power estimation in wheelchair racing is useful for athletes and coaches. A non-invasive method to estimate mechanical power is by using inertial measurement units (IMUs) to estimate the power lost to resistive forces during wheelchair propulsion. During the recovery phase, no propulsive force acts on the athlete...

A baseball pitch is an explosive and dynamic motion during which one of the highest angular rates achieved by the human body in sports activity was noted. The nature of the baseball pitch puts shoulder structures at risk, and one of the most common injuries among pitchers is a rotator cuff tear, frequently connected with internal impingement. It...

Activity classification in sports is a powerful tool for athlete monitoring, enhancing performance and injury prevention. In handball, detection and classification of throws during a practice or a (practice) match has not been done. Therefore, the aim of this study is to use machine learning algorithms to detect handball throws and to classify...

The main resistive force acting on the wheelchair during manual wheelchair propulsion is the rolling resistance. The magnitude of this rolling resistance is heavily influenced by the actions of the wheelchair user. By optimizing how wheelchair athletes move, this rolling resistance can be minimized, thereby improving their effective power output...

Classification of pitch types outside the laboratory or game environment provide benefits in designing and outlining training routines to reduce injury and improve performance. Current classification approaches are based on vision-based optical data, however these optical data is often not available in training sessions. The aim of the current...

Ulnar collateral ligament (UCL) injuries are common in baseball pitching. The elbow external valgus torque is assumed to be indicative for the applied load on the UCL. This study investigated the maximum external valgus and extension torque and their corresponding load variability during a baseball pitch and the relationship between the...

Aerodynamics are an important factor in competitive cycling and easy and realistic aerodynamic measurement methods are helpful for the riders and coaches. An indoor velodrome, minimizing the environmental effects, could be a suitable location for quick, reliable, and easy measurements on cyclist CdA. However, the effect of banked straights and...

The relay in short track skating is a team effort with the possibility to regain strength during the race by performing an exchange with a team member. Couples can gain time and conserve kinetic energy with a well performed exchange. However, the exchange is a difficult operation. With few studies done to find out what makes a good relay...

The purpose of this study was to determine whether a change of an accuracy restriction (AR) leads to a change in the separation time between the peak rotational velocities of the pelvis and the trunk during a pitching motion, while the ball velocity is kept constant. The peak rotational velocities of the pelvis, trunk, the separation time and...

Dutch children achieve an insufficient amount of physical activity. For that reason, Delft University of Technology is looking to develop a wearable that contributes to motivating children to move more frequently and more intensely while collecting data on the movements made by its wearer. In this thesis it was investigated whether it would be...

Energy harvesting has become a popular topic for battery substitution in recent years. In particular, mechanical vibrational energy, one of the most common energy sources, has been intensely studied. Piezoelectric materials play a crucial role in vibrational energy harvesting as they can directly convert the mechanical energy to the desired...

Baseball pitching is a movement wherein an external valgus moment around the elbow joint regularly causes an ulnar collateral ligament (UCL) injury. A proven relationship between the muscle activation around the elbow joint and its capacity to compensate for the external valgus moment during a baseball pitch allows predicting the likelihood of a...

One interesting part of the application of human activity recognition is sports motion recognition and classification. In recent years, many commercial wearable devices have been used for recording and supervising motion data information during sports. However, their claimed high-accuracy results but motion recognition and classification method...

The recent advancements in inertial sensors technology and its promising results in motion tracking, catch the expert’s eyes to these new horizons in sports engineering. In baseball, which is the interest of this study, almost 90% of the pitchers got injured once a year due to wrong training and pitching techniques. Screening and real-time...

Many falls occur in speed skating, most of which end up in protective padding that is placed along the ice rink. In this research project a testing method was established that can be used to test the influence of different padding parameters on the performance of the padding in relation to the skaters’ injury risks. An existing numerical model...

Musculoskeletal models can be used to distinguish too short or too slow muscles in Cerebral Palsy patients. Therefor muscle-tendon geometry needs to be modeled accurately in order to predict the need and effectiveness of muscle-tendon lengthening. This geometry is strongly related to the location and orientation of the joint centres. In clinic...

The technique of speed skating is unique in comparison to other sports that require human propulsion. Skaters generate a forward velocity by pushing off sideways. The ideal push-off technique is a trade-off: a more sideward directed push-off facilitates power production, but a more forward directed push-off increases the transfers rate of push...
