Validation of AI-based markerless gait event detection during perturbed walking using smartphone videos from two camera perspectives
Background Perturbation-based balance training (PBT) requires objective quantification of reactive stepping responses, yet gait event detection during perturbed walking remains methodologically challenging. Markerless smartphone-based gait analysis offers a scalable alternative to laboratory motion capture systems, but its robustness under perturbation-induced gait irregularities is insufficiently validated. This pilot study including five partic…
Effects of jump training on power, strength, balance and aerobic performance in non-exercising young adults
Physical inactivity is a major risk factor for noncommunicable diseases and associated mortality. A high-intensity jump training has proven to be efficient in counteracting inactivity related declines in physical function during two months of bed rest. In the present study, we tested the effects of such a training program under real-life conditions. Seventy-five young adults (38 female, 23 ± 3 years) were randomly assigned to either a training or…
In-game monitoring of adolescent handball players
Subjective fatigue measures, particularly RPE, were more sensitive than objective neuromuscular testing for detecting match-related fatigue in adolescent handball players. Coaches' ratings aligned increasingly with players' perceptions, highlighting the practical value of subjective monitoring for in-game load management
Reliability of the adapted compensatory arm and leg movements scale during perturbation treadmill walking in older adults
The A-CALM scale showed high intra-rater consistency and moderate-to-substantial inter-rater agreement, with greater reliability for arm than leg movements. Single-rater use is recommended to enhance stability, while future work should refine leg scoring and validate the scale in larger cohorts with outcomes like falls and functional decline
A complex systems view on physical activity with actionable insights for behaviour change
Motor learning in golf—a systematic review
Golf is a sport that consists of complex movement skills that need to be executed with utmost precision. Consequently, motor skill learning plays a crucial role in golf, and large numbers of studies address various methods of motor learning. In the present review, we give a systematic overview of randomized controlled trials (RCTs) on motor learning of golf-specific motor skills. Three electronic databases were searched for RCTs looking at the ef…
Interaction between the leg recovery test and subjective measures of fatigue in handball players
Background The physical and mental demands of handball during training or competition often lead to fatigue which can impair performance. Many attempts have been made to assess the level of fatigue in athletes either by objective (neuromuscular performance) or subjective (questionnaires) measures, however, their interplay over short-, mid-, and long-term periods is currently unknown. Knowledge about both types of assessments is important as load …
Associations between upper quarter Y-balance test performance and sport-related injuries in adolescent handball players
Handball players are at a high risk of suffering a sport-related injury. Recent studies in various adult populations (e.g., US Army soldiers/warrior athletes, and military members) showed that poor scores in the upper quarter Y-balance test (YBT-UQ) are related to an increased risk of injury. Yet, it is unclear whether this also applies to adolescent handball players. Thus, the present study aims to determine if pre-season YBT-UQ performance is a…
Correlations between core muscle strength endurance and upper-extremity performance in adolescent male sub-elite handball players
Handball is an Olympic contact sport with high physical, tactical, and technical demands by the players. Out of the different techniques, throwing is the most important one to be able to score. The objective of the study was to investigate the relationships between core muscle strength endurance (Bourban test: ventral, dorsal and lateral chain) and shoulder mobility/stability (Upper Quarter Y Balance test [YBT-UQ]) as well as throwing velocity in…
The validity and reliability of counter movement jump height measured with the Polar Vantage V2 sports watch
The purpose of the present study was to assess the validity and reliability of the jump height measured by the Polar Vantage V2 sports watch in comparison to a gold-standard force plate measurement. Fifteen healthy adults, seven female, age 20-42 years participated in the study and performed six sets of three CMJs, on two consecutive days. The participants wore the Polar Vantage V2 sports watch (Polar Electro Oy, Kempele, Finland) whilst performi…

As a critical journal for all classical studies, the GNOMON fosters the links between the distinct classical disciplines. It has thus an exceptional position among the classical review journals and allows familiarization with research and publications in neighbouring disciplines. The reviews address an international readership from all fields in classical studies. The GNOMON publishes reviews in German, English, French, Italian and Latin

Der Chor in den Tragödien des Aischylos
In der ersten Monographie zum Chor in allen sechs erhaltenen Tragödien des Aischylos (525-456 v.Chr.), des "Vaters der Tragödie", steht die Frage im Mittelpunkt, welche Funktion der Chor für den Zuschauer hat. Nach einem methodischen Teil, der auch eine Darstellung des frühgriechischen Chores insgesamt enthält und in dem ein rezeptionsästhetisches Interpretationsparadigma aufgestellt wird, orientieren sich die ausführlichen Einzelinterpretationen…
