Introduction
Armin works at the Institute for Sports and Sport Science, University of Kassel. His research interests refer to the biomechanics of swim starts and turns, instability (or better: metastability) strength training to be applied to older adults as well, and non-conscious action control in ball games and combat sports. Armin is conducting projects, as well, in Teacher Education. One of his current projects concerns digital teaching materials and AI applications to be used in high school.

Conference Paper
Mit zunehmendem Alter nehmen die körperliche und kognitive Leistungsfähigkeit ab. Während es keine Zweifel an den positiven Auswirkungen körperlicher Betätigung auf Kraft- und Gleichgewichtsfaktoren gibt, ist die Evidenz für positive Effekte von Kraft- und Gleichgewichtstraining auf kognitive Funktionen (kF) eher uneinheitlich. Als mögliche Wege zu...

In recent years, there has been a substantial increase in the number of studies investigating the effects that transcranial direct current stimulation (tDCS) can have on exercise performance. Currently, there exists substantial conflict in the literature, with many studies reporting that 10-20 min of tDCS can result in augmented performance, while...
Article
Elite swimmers are individual athletes competing mostly on their own. However, when competing in a relay team, they are exposed to social influences possibly leading to effort gains compared to their individual performance. This study investigated effort gains in relay team members during 4 x 100 m freestyle races of Olympic Games and World Champio...
Article
The purpose of the present study was twofold: (i) to compare the kinematic characteristics of individual and relay swimming starts; and (ii) to relate the kinematic variables to 5 m performance for both starts. Twelve elite-level swimmers performed 2 × 25 m at maximal effort (one with an individual and one with a relay start randomly). Two-dimensio...

›Using resistance training on unstable supports or with instability devices athletes aim to prepare their neuromuscular system for sudden and unforeseen impairments in equilibrium impeded by the environment or through sports partners. In contrast to athletes, older adults aim to avoid such situations impeded by instability to reduce a possible risk...

Background. This study investigated the effects of two 14-week resistance training protocols with different repetition duration (RD) performed to muscle failure (MF) on gains in strength and muscle hypertrophy as well as on normalized electromyographic (EMG) amplitude and force-angle relationships. Methods. The left and right legs of ten untrained...

For more than twenty years we have been studying perceptual-motor processes related to penalty kicks with decelerated run-ups. Our starting point goes back to the 1990s with Winton Rufer (previously with SV Werder Bremen) and Rodolfo Esteban Cardoso (previously with SC Freiburg) exercising pentalty kicks with decelerated run-ups. Interviews with bo...

In swimming relay races, various start techniques are performed by swimmers, but it remains unclear which technique leads to a better start performance. Therefore, the purpose of the present study was to compare the kinematic characteristics of different relay start techniques with the new starting block Omega OSB11. Eleven international youth swim...

Aging is associated with declines in physical and cognitive performance. While there is no doubt about beneficial effects of physical exercise on proxies of strength and balance, the overall evidence for positive effects of resistance and balance training on executive functions is rather inconsistent. Whether the simultaneous exercising of strength...

Is the control of movement less stable when we walk or run in challenging settings? Intuitively, one might answer that it is, given that challenging locomotion externally (e.g. rough terrain) or internally (e.g. age-related impairments) makes our movements more unstable. Here, we investigated how young and old humans synergistically activate muscle...

A means to compensate for perturbations is to employ motor synergies that act to stabilize or provide similar trial-to-trial output. Whereas evidence exists that synergies related to the upper extremities can be trained, the extent to which lower limb synergies can be altered remains unknown. The purpose of this study was to evaluate whether resist...

Is the control of movement less stable when we walk or run in challenging settings? One might intuitively answer affirmatively, given that adding constraints to locomotion (e.g. rough terrain, age-related impairments, etc.) imply less stable movements.

Short change-over times (COT) in swimming relays can play an important role in winning a race. Therefore, experts recommend to specifically train change-overs between swimmers to minimize COT (Maglischo, 2003; Siders, 2010; Saavedra et al., 2014). But, change-overs in swimming constitute a quite risky situation, since a false start and hence a disq...

The aim of this study was to examine the importance of the change-over time in swimming relay races. Top-class international 4 x 100 m freestyle races were analysed across a 10-year period including three Olympic Games and five European and World Championships. A total of 220 swimmers (116 female, 104 male) were included in this study with an avera...

Most actions we perform in daily life consist of multiple movement elements. In two Simon task experiments, we investigated the impact of stimulus-response compatibility on planning and execution of action sequences. A total of 38 participants were instructed to perform action sequences consisting of multiple key presses (two to four key presses) a...
Chapter
Swimming a relay is different from swimming in an individual race. The most visible difference can be found in the starting behavior from the block. For the individual start, swimmers initiate, at rest, their take-off movement as soon as a starting signal appears. For relay starts, swimmers may initiate their take-off behavior any time they wish. H...

In our daily life, we regularly walk and run in complex environments. To deal with unexpected perturbations, the central nervous system must adaptively modify its control strategies. However, the continuous integration of sensory and motor information likely undergoes some simplification for achieving precise control, possibly by activating muscles...

The accurate detection of gait events is essential for clinical gait analysis. Aside from speed, surface characteristics like planarity and compliance can affect gait kinematics. Therefore detection of kinematic gait events on uneven surfaces may be inaccurate. To date, no study has investigated the possible influence of surface characteristics on...

Visually perceived motion can affect observers' motor control in such a way that an intended action can be activated automatically when it contains similar spatial features. So far, effects have been mostly demonstrated with simple displays where objects were moving in a two-dimensional plane. However, almost all actions we perform and visually per...

In the past, studies and book recommendations on relay starts in swimming have been predominantly focused on the change-over time (COT) as a performance criterion. Aside from the circular backswing start with parallel foot placement, few studies have analysed differences in the take-off movement including step approaches as well. Although trends co...

Cognitive and neurocognitive approaches to human healthy aging attribute age-related decline to the biologically caused loss of cognitive-control functions. However, an embodied-cognition approach to aging implies a more interactive view according to which cognitive control emerges from, and relies on a person’s active encounters with his or her ph...

A new testing procedure is introduced to evaluate the alactic running performance in a 10s sprint task with near-maximal movement velocity. The test is performed on a motor-equipped treadmill with inverted polarity that increases mechanical resistance instead of driving the treadmill belt. As a result, a horizontal force has to be exerted against t...
