Is young age a limiting factor when training balance? Effects of child-oriented balance training in children and adolescents

Wälchli, Michael ; Ruffieux, Jan ; Mouthon, Audrey ; Keller, Martin ; Taube, Wolfgang

In: Pediatric Exercise Science, 2017, p. 1–26

Purpose: Balance training studies in children reported conflicting results without evidence for improvements in children under the age of eight. The aim of this study therefore was to compare balance training adaptations in children of different age groups to clarify whether young age prevents positive training outcomes.Method: The effects of five weeks of child-oriented balance training were...

Enhanced jump performance when providing augmented feedback compared to an external or internal focus of attention

Keller, Martin ; Lauber, Benedikt ; Gottschalk, Marius ; Taube, Wolfgang

In: Journal of Sports Sciences, 2015, vol. 33, no. 10, p. 1067–1075

Factors such as an external focus of attention (EF) and augmented feedback (AF) have been shown to improve performance. However, the efficacy of providing AF to enhance motor performance has never been compared with the effects of an EF or an internal focus of attention (IF). Therefore, the aim of the present study was to identify which of the three conditions (AF, EF or IF) leads to the...

Ice skating promotes postural control in children

Keller, Martin ; Röttger, K. ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sports, 2014, vol. 24, no. 6, p. e456-461

High fall rates causing injury and enormous financial costs are reported for children. However, only few studies investigated the effects of balance training in children and these studies did not find enhanced balance performance in postural (transfer) tests. Consequently, it was previously speculated that classical balance training might not be stimulating enough for children to adequately...

Supervised slackline training improves postural stability

Pfusterschmied, Jürgen ; Buchecker, Michael ; Keller, Martin ; Wagner, Herbert ; Taube, Wolfgang ; Müller, Erich

In: European Journal of Sport Science, 2013, vol. 13, no. 1, p. 49-57

The present study investigated whether or not four weeks of supervised slackline training (SLT) performed on nylon webbing improves postural stability. Twenty-four healthy adults participated in the study and were assigned to either SLT (n=12) or a control (CON) group (n=12). The SLT group completed a four week training program, while the CON group received no training. Centre of gravity...

Spinal reflex plasticity in response to alpine skiing in the elderly

Lauber, B. ; Keller, Martin ; Gollhofer, Albert ; Müller, E. ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sports, 2011, vol. 21, no. s1, p. 62–68

The present study was designed to assess the influence of 12 weeks (28.5±2.6 skiing days) of alpine skiing on spinal reflex plasticity, strength and postural control in senior citizens. Therefore, soleus H-reflexes and postural stability were measured during bipedal quiet and unstable stance in 22 (12 male and 10 female) elderly subjects aged 66.6±1 years. Furthermore, the maximal isometric...
