In this article, we outline the overarching research program that links the specific research stran...
INTRODUCTION
In swimming, the standard method of monitoring heart rate (HR) in practice is the palpation of the pulse for 10 seconds at the end of a training set. However, this method has an error of at least 6 bpm. A more accurate ECG-based method is to measure the HR with a chest strap. But also this method is error-prone as the strap slips often...

The ability for quick multidirectional accelerations is crucial for athletic performance in team and racquet sports. So far, there has been little research dedicated to different initial step patterns usually applied by players. Therefore, the present study investigated the kinematic characteristics and effectiveness of the following step patterns:...
Tennis match performance is often evaluated by a player's internal (heart rate) and external (match analytics) outcomes. Numerous factors could influence these outcomes, including the time of day, which may be advantageous or not depending on a player's chronotype. This study aimed to determine the influence time of day, chronotype and sleep–wake b...

INTRODUCTION | In many sports, heart rate (HR) monitoring is used to quantify internal training load and to control and steer exercise intensity [1]. In swimming, the standard method of ECG-based HR recording is error-prone, as chest straps may slip during swimming and wall push-offs, especially when no swim suit is worn. The optical HR sensor Veri...
Abstract to the oral presentation of my master thesis during the 27th annual ECSS 2022 in Sevilla, Spain.
Talent identification often begins at the age of entry into a sport: namely, even under the age of 9 years old (U9). However, the success of such early talent identification is questionable. Therefore, the aim of this long-term retrospective study is to examine whether today’s more successful junior tennis players already differed from today’s less...

Poster Talk --- INTRODUCTION | Exercise intensity was described as a main determinant of acute changes in heart rate variability (HRV) following endurance-based exercise [1]. Yet, it remains unclear if (intensity-dependent) acute HRV patterns can be consistently observed in single athletes, due to a typically large day-to-day variability. We theref...

Introduction
Assessing changes in fatigue, fitness and (aerobic) performance with exercise heart rate (HRex) during submaximal, non-exhaustive tests became very popular in training research and practice. As HRex may decrease due to (acute) fatigue and/or (long-term) adaptation [1], contextualization and multivariate approaches are required for a va...
