Heart rate variability–guided endurance training
Heart rate variability (HRV) has been used to guide individualized endurance training prescription. By supporting training adjustments according to recovery status, HRV-guided approaches may improve the alignment between training load and physiological readiness. However, the practical value depends on the decision framework used to translate HRV measurements into training prescriptions. This paper applies a Strengths, Weaknesses, Opportunities, …
A comparison of lessons planned by different publicly available large language models in the context of physical education
Introduction Large Language Models (LLMs) have the potential to assist teachers, particularly in lesson planning. The quality of lessons generated by various LLMs remains unexplored. Methods We investigated the quality of different LLMs for lesson planning, using the basketball layup as example and surveying experts in the field. A prompt was submitted to three LLMs (GPT-4o, Claude Sonnet, and Google Gemini). Twenty-eight quality criteria to eval…

Acute physiological, biomechanical, and perceptual responses of runners wearing downward-curved carbon fiber insoles
In a randomized controlled cross-over study ten male runners (26.7 ± 4.9 years; recent 5-km time: 18:37 ± 1:07 min:s) performed an incremental treadmill test (ITT) and a 3-km time trial (3-km TT) on a treadmill while wearing either carbon fiber insoles with downwards curvature or insoles made of butyl rubber (control condition) in light road racing shoes (Saucony Fastwitch 9). Oxygen uptake, respiratory exchange ratio, heart rate, blood lactate c…
The proportional distribution of training by elite endurance athletes at different intensities during different phases of the season
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 this field, as well as for training by these athletes. Altogether, we included 175 TIDs, of which 12…
Type and intensity distribution of structured and incidental lifestyle physical activity of students and office workers
The present study provides initial insights regarding the type, amount, and distribution of intensity of structured and incidental lifestyle PA ≥ 50% HRR. Findings show a substantial amount of incidental lifestyle PA during waking hours and display the importance of promoting a physically active lifestyle. Future research could employ ambulatory assessments with integrated electronic diaries to detect information on the type and context of MVPA d…
The Relationship Between the Distribution of Training Intensity and Performance of Kayak and Canoe Sprinters
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 and 2, as well as during the period of competition (CP) (total monitoring period: 37 weeks). The zones…
Some Personal Advice Concerning How to Write Precise, Concise and Eloquent Research Articles
Naturally, you want other scientists to read your article and the title is your major form of advertising. Make it as specific and concrete as possible. If a conclusion can be stated simply, do so and indicate its significance. At the same time, do these things as concisely as possible, since this might possibly
Virtual Training of Endurance Cycling - A Summary of Strengths, Weaknesses, Opportunities and Threats
Virtual online training has emerged as one of the top 20 worldwide fitness trends for 2021 and continues to develop rapidly. Although this allows the cycling community to engage in virtual training and competition, critical evaluation of virtual training platforms is limited. Here, we discuss the strengths, weaknesses, opportunities and threats associated with virtual training technology and cycling in an attempt to enhance awareness of such aspe…
The Impact of the German Strategy for Containment of Coronavirus Sars-CoV-2 on Training Characteristics, Physical Activity and Sleep of Highly Trained Kayakers and Canoeists
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 containment of Coronavirus SARS-CoV-2 on March 23, 2020, 14 highly trained athletes (VO2peak: 3,162 ±…
