As a predictor for anerobic performance in many sports, the maximal glycolytic rate (νLamax) is assessed in a laboratory setting. However, differences between lab-based test and a sport specific field setting remain unclear. The aim of this study was to compare ergometer and on-water tests for νLamax in elite youth canoe polo players. Fifteen elite...

Purpose This study investigates the intra- and inter-individual time courses of physiological adaptation to high-intensity interval training (HIIT), comparing single and duplicate pre-to-post testing with session-by-session analysis to more accurately identify “genuine” adaptations. Methods Seventeen participants (nine men) engaged in repeated 4x4...

BACKGROUND Inadequate sleep is prevalent among athletes, affecting adaption to training and performance. While education on factors influencing sleep can improve sleep behaviors, Large Language Models (LLMs) may offer a scalable approach to provide sleep education to athletes. OBJECTIVE This study aims to i) investigate the quality of sleep recomm...

Purpose The aim was to assess the accuracy of a continuous blood glucose monitoring (CGM) device (Abbott FreeStyle Libre 3) against capillary blood glucose measurement (BGM) before, during, and after an intense lower body strength training session in connection with high- versus low-carbohydrate breakfasts. Methods Nine adults (22 ± 2 years) compl...

Resistance training constitutes a crucial element in the athletic training regimen for augmenting performance abilities or preventing injuries. Conventionally, resistance training programs are designed by prescribing relative intensities as a percentage of the individual’s one-repetition maximum for a predetermined number of sets and repetitions. H...

The present review examines retrospective analyses of training intensity distribution (TID), i.e., the proportion of training at moderate (Zone 1, Z1), heavy (Z2) and severe (Z3) intensity by elite-to-world-class endurance athletes during different phases of the season. In addition, we discuss potential implications of our findings for research in...

Beim Velocity-based Training (VBT) wird die Geschwindigkeit des Gewichts oder der Hantel während einer Einzelwiederholung im Krafttraining gemessen. Es ermöglicht eine präzise Steuerung der Intensität und Ermüdung im Krafttraining, basierend auf den individuellen Kraft und Leistungsfähigkeiten der Sportler. Durch die Verwendung von VBT können Train...

Background Research results on the training intensity distribution (TID) in endurance athletes are equivocal. This non-uniformity appears to be partially founded in the different quantification methods that are implemented. So far, TID research has solely focused on sports involving the lower-body muscles as prime movers (e.g. running). Sprint kaya...

Purpose: To evaluate retrospectively the training intensity distribution (TID) among highly trained canoe sprinters during a single season and to relate TID to changes in performance. Methods: The heart rates during on-water training by 11 German sprint kayakers (7 women, 4 men) and one male canoeist were monitored during preparation periods (PP) 1...

Purpose: (1) To compare various physiological indicators of performance during a 5 × 1500-m incremental kayak test performed on an ergometer and on-water and (2) to analyze the relationships between these indicators and the actual competition performance of elite sprint kayakers, aiming to provide information to coaches for evaluating and planning...

Dehnen ist oft ein fester Bestandteil von Training und Therapie. Doch notwendig, um gesund und leistungsfähig zu bleiben, scheint diese Intervention gar nicht immer zu sein. Die Trainings- beziehungsweise Therapiezeit könnte demnach bei manchen Athleten und Patienten sinnvoller genutzt werden.

This study was designed to assess systemic cardio-respiratory, metabolic and perceived responses to incremental arm cycling with concurrent electrical myostimulation (EMS). Eleven participants (24 ± 3 yrs; 182 ± 10 cm; 86 ± 16.8 kg) performed two incremental tests involving arm cycling until volitional exhaustion was reached with and without EMS of...

Aim: To characterize the impact of the German strategy for containment of Coronavirus SARS-CoV-2 (social distancing and lockdown) on the training, other habitual physical activity, and sleep in highly trained kayakers and canoeists. Method: During the 4 weeks immediately prior to and following the beginning of the German government's strategy for c...

Purpose: (1) To compare various physiological indicators of performance during a 5 × 1500-m incremental kayak test performed on an ergometer and on-water and (2) to analyze the relationships between these indicators and the actual competition performance of elite sprint kayakers, aiming to provide information to coaches for evaluating and planning...

The aim of the present study was to analyze the correlation between aerobic performance measures during an incremental test on a kayak-ergometer and on-water competition race times in highly trained kayakers. Fourteen participants performed an incremental test on a kayak ergometer one to two weeks post an official competition where they performed a...

Introduction The sport of Olympic sprint kayaking depends on both high aerobic and strength capabilities. Concurrent development of these components is a common training aim. However, concurrent training (CT) appears to have a negative impact on strength development, with no detrimental effects on endurance performance. García-Pallarés et al. (2010...
