The purpose of this study was to investigate the effect of a short-term Swiss ball training on core stability and running economy. Eighteen young male athletes (15.5 +/- 1.4 years; 62.5 +/- 4.7 kg; sigma9 skinfolds 78.9 +/- 28.2 mm; VO2max 55.3 +/- 5.7 ml.kg(-1).min(-1)) were divided into a control (n = 10) and experimental (n = 8) groups. Athletes were assessed before and after the training pr...

A 6-wk group balance-training program was conducted with physically active older adults (based on American College of Sports Medicine requirements) to investigate the effect of dose-related static and dynamic balance-specific training. All participants, age 60-87 yr, continued their regular exercise program while adding balance training in 1 of 3 doses: three 20-min sessions/wk (n = 20), one 20...

STUDY DESIGN Randomized clinical trial. OBJECTIVE To examine the effect of attentional focus instructions during training on the transfer of a learned balance capability to a more challenging condition among subjects with ankle ligament injury. BACKGROUND Current evidence suggests that instructions inducing an external focus of attention may be more effective at promoting learning than inst...

We aimed to examine the trial-to-trial changes in the reactive balance response to large magnitude slip-like treadmill perturbations in stance and whether the acquired adaptive changes could be appropriately scaled to a higher intensity perturbation. Seventeen young adults experienced 15 slips for training on level I intensity. Pre- and post-training slips were delivered at a higher intensity (...

Various forms of mental training have been shown to improve performance on cognitively demanding tasks. Individuals trained in meditative practices, for example, show generalized improvements on a variety of tasks assessing attentional performance. A central claim of this training, derived from contemplative traditions, posits that improved attentional performance is accompanied by subjective i...

The talk consists of two parts: in the first part, we review the notion of algorithmic stability to obtain bounds on generalization error using training error estimates. We introduce the new notion of training stability that is sufficient for tight concentration bounds in general and is both necessary and sufficient for PAC learning. In the second part, we consider several algorithms for which ...

ABSTRACT Introduction: Recent research shows that swimmers with greater stability and better balance reflect water performance adjustment ability. Objective: Explore the influence of training on fitness swimmers. Methods: The volunteers selected in this paper were aged 18 to 22 years old a sports school. They randomly divided into experimental control groups for an experiment lasting 8 weeks. B...
