Summary: This study investigated the exercise performance and ventricular function of ARVC patients during follow-up, taking into account their adherence to exercise restriction recommendations. The results showed that if intensive sports activities are not discontinued, exercise capacity and left ventricular function of athletes with ARVC deteriorates over time. Therefore, it is essential for all ARVC patients to strictly adhere to the recommendation to cease intense sports activity in order to halt disease progression.

Summary: A novel reliability evaluation scheme for quantitative reliability calculation of power converter in switched reluctance motor system is proposed, combining electrical model, thermal circuit model, and dynamical Markov model. The proposed failure criterion simplifies the model, decreases the number of states, and avoids result divergence, emphasizing the interconnected relationship between the three models. The validity of the proposed reliability evaluation scheme is verified through simulations and experiments.

Summary: Recreational divers are required to undergo medical examinations, but current bicycle ergometry systems may not effectively assess diving performance. Underwater physical performance is significantly reduced compared to on land, leading to fatigue and potential diving incidents. Thus, it is crucial for divers to understand and improve factors limiting their physical performance underwater.

Summary: This study presents the challenges faced in implementing a new converter topology for switched reluctance motor drives. A novel converter configuration that can directly excite the motor from the AC grid supply is proposed. The uniqueness of this converter topology lies in its ability to use 4 switches per phase, increasing system redundancy. Additionally, this topology is well-suited for SRM excitation due to the structure of the machine coils.

Summary: This paper explores the potential of the JT/ST algebraic relationship in identifying ischemic changes in the human cardiovascular system and highlights the specifics of complex dynamical processes during the load and recovery processes in the heart system through a suggested visualization technique. It demonstrates the benefit of the nonlinear algebraic relationship between the duration of the JT interval and the ST amplitude for interpreting dynamical processes in the human cardiovascular system more deeply.

Summary: This paper proposes a method focusing on the influence of the change of the turn-on angle and turn-off angle on the vibration of Switched Reluctance Motors (SRMs). The study shows that by varying the switching angles, the vibration can be effectively reduced, providing a new perspective on vibration suppression for SRMs.

Summary: A novel position sensorless torque control strategy is proposed for SRMs with fewer current sensors to decrease cost, enhance torque performance, and improve system reliability. Real-time rotor position can be obtained using a flux linkage-current-based method, and instantaneous phase torque and torque sharing function can be determined for direct torque control based on current and position information, leading to significantly improved system reliability and achieving a compact, high-reliable, and high-performance SRM drive.

Summary: This article introduces the use of cascade repeaters in a multiload inductive power transfer (ML-IPT) system. The cascade repeaters serve as both power transmitters and load carriers, and high-order compensations are designed to achieve constant load currents. A bilateral-excitation (BE) scheme is proposed to improve output currents and system reliability.

Summary: Quantification of ATP7B peptide effectively identified Wilson disease patients in 92.1% of presented cases, reducing ambiguities from ceruloplasmin and genetic analysis. It provides clarity to patients with ambiguous genetic results, aiding significantly in noninvasive diagnosis. A proposed diagnostic score and algorithm incorporating ATP7B peptide concentrations can be a rapid supplement to current Leipzig scoring systems.

Summary: This study aims to describe the racing and training demands of the Cape Epic. The results show that participants need to sustain high submaximal power outputs for several hours and repeat high-intensity efforts throughout the race. A well-balanced training program with a pyramidal intensity distribution can serve as an optimal starting point for training approaches.

Summary: The study showed that IP significantly reduced mean arterial pressure during metaboreflex activation, likely due to a reduced end diastolic volume. MP was significantly higher during IP compared to SHAM treatment, while PPT showed no significant differences. MP remained unchanged during exercise but was significantly lower during PEMI following IP.

Summary: This study assessed whether adding intermittent vibration to varied-intensity work intervals could further increase cyclists' fractional maximal oxygen uptake. The results showed that adding vibration did not increase the maximal oxygen uptake, and further research is needed to determine the effect of intermittent vibration on cyclists' adaptive stimulus during high-intensity interval training.

Summary: The purpose of this study was to compare the ability of different methods of relative intensity prescription to normalize performance, physiological, and perceptual responses to HIIT between individuals. The study found that all relative intensity normalization methods were poor, with high inter-individual variability, making it difficult to predict individual responses to HIIT. Therefore, the present study suggests that the investigated methods of intensity prescription do not normalize acute responses to HIIT between individuals.

Summary: This study examined the physiological responses during exercise at FTP and FTP+15W. The results showed that the time to task failure and VO2peak were significantly different between FTP and FTP+15W. Additionally, there was a significant difference in blood lactate levels. Therefore, FTP should not be considered a threshold marker for heavy and severe intensity.

Summary: The purpose of this study was to investigate the effects of exercise intensity normalisation on intra- and inter-individual acute and adaptive responses to an interval training programme. The results showed that normalising exercise intensity based on the maximal sustainable work rate achieved in a self-paced interval training session led to higher training completion rates. Ratings of perceived exertion and heart rates were not affected by the type of intensity normalisation, but the %(W)over dot(max-SP) group had lower intra-individual variability. There were individual responses in maximal oxygen uptake and self-paced interval training performance, but the inter-individual variability was similar between groups. The study concluded that %(W)over dot(max-SP) should be used to normalise completion rates in interval training, but the variability in adaptive responses may not be influenced by the way exercise intensity is normalised.
