Challenge Not Only to the Muscles - Surface Instability Shifts Attentional Demands in Young and Older Adults While Performing Resistance Exercise
(2023-11-28)
Regular physical activity is an important factor in maintaining and improving physical and cognitive functions in an aging society. Compared to resistance and endurance training, motor tasks with attentional demands and cognitive activation are considered to have a greater potential for improving executive functions. Unstable devices increase the coordinative demands and could thus lead to increased cognitive engagement during acute resistance exercises. This study aimed to investigate the required attentional resources ...

Maintain your mind, mantain your focus: Effects of focused attention and intensity in experienced runners
(2024-02-26)
The intensity that people choose for their endurance activities has a major influence on their affective experience. Furthermore, the direction of attention (e.g., internal or external) during endurance activities may significantly influence performance and ersonal perceptions. Therefore, in the current study, we focus on the interaction between intensity and attentional focus. We aim to address the question of whether adopting an internal (IAF; breathing) or an external attentional focus (EAF; environment), compared ...

Instability Resistance Training improves Working Memory, Processing Speed and Response Inhibition in Healthy Older Adults: A Double-Blinded Randomised Controlled Trial
(2020-02-13)
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 and balance, i.e., instability resistance training, promotes executive functions in older adults is unknown. In the present trial, we tested the effects of unstable vs. ...

Accuracy of outcome anticipation, but not gaze behavior, differs against left- and right-handed penalties in team-handball goalkeeping
(Frontiers Research Foundation, 2015)
Low perceptual familiarity with relatively rarer left-handed as opposed to more common right-handed individuals may result in athletes' poorer ability to anticipate the former's action intentions. Part of such left-right asymmetry in visual anticipation could be due to an inefficient gaze strategy during confrontation with left-handed individuals. To exemplify, observers may not mirror their gaze when viewing left- vs. right-handed actions but preferentially fixate on an opponent's right body side, irrespective of ...

Lower-extremity resistance training on unstable surfaces improves proxies of muscle strength, power and balance in healthy older adults: a randomised control trial
(2016-11-24)
Background:
It is well documented that both balance and resistance training have the potential to mitigate intrinsic fall risk factors in older adults. However, knowledge about the effects of simultaneously executed balance and resistance training (i.e., resistance training conducted on unstable surfaces [URT]) on lower-extremity muscle strength, power and balance in older adults is insufficient. The objective of the present study was to compare the effects of machine-based stable resistance training (M-SRT) and ...

“Some hate it, others love it”: Formation of automatic and reflective affective processes toward exercising in fitness centers and mountain biking
(2022-03-18)
Based on a dual process approach, this study was conducted to test whether automatic affective processes toward exercise are not only interrelated with the amount of exercise but also distinctive for different types of exercise. In a quasi-experimental setting, N = 60 participants (30.87 years ± 7.53; 33% female) completed an Evaluative Priming task to assess automatic affective processes toward exercising in fitness centers, mountain biking and exercise in general and completed a questionnaire about their exercise ...

Weight estimations with time-reversed point-light displays
(2020-11-24)
Interpreting other’s actions is a very important ability not only in social life, but also in interactive sports. Previous experiments have demonstrated good estimation performances for the weight of lifted objects through point-light displays. The basis for these performances is commonly assigned to the concept of motor simulation regarding observed actions. In this study, we investigated the weak version of the motor simulation hypothesis which claims that the goal of an observed action strongly influences its ...

Left preference for sport tasks does not necessarily indicate left-handedness
(2014)
In the elite domain of interactive sports, athletes who demonstrate a left preference (e.g., holding a weapon with the left hand in fencing or boxing in a ‘southpaw’ stance) seem overrepresented. Such excess indicates a performance advantage and was also interpreted as evidence in favour of frequency-dependent selection mechanisms to explain the maintenance of left-handedness in humans. To test for an overrepresentation, the incidence of athletes’ lateral preferences is typically compared with an expected ratio of ...

Instability Resistance Training Decreases Motor Noise During Challenging Walking Tasks in Older Adults: A 10-Week Double-Blinded RCT
(2019-02-27)
Locomotor stability is challenged by internal perturbations, e.g., motor noise, and external perturbations, e.g., changes in surface compliance. One means to compensate for such perturbations is to employ motor synergies, defined here as co-variation among a set of elements that acts to stabilize, or provide similar trial-to-trial (or step-to-step) output, even in the presence of small variations in initial conditions. Whereas evidence exists that synergies related to the upper extremities can be trained, the extent ...
