Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise

2015

International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …

Electromyostimulation and EMG real time device with muscle fatigue estimation

2012

International audience; This study presents a system composed of an electromyostimulation (ES) and an electromyograph (EMG) modules which analyze in real time EMG during ES and proposes a new method based on wavelet decomposition to analyze changes in M wave. It leads to introduce a new muscular fatigue index. Different methods to filter the EMG noise are then compared. The results show that this new index gives reliable and robust results even when noise corrupts significantly the signal.

''No Gender Difference in Peak Performance in Ultra-Endurance Swimming Performance - Analysis of the 'Zurich 12-h Swim' from 1996 to 2010''

2012

Eichenberger, Evelyn | Knechtle, Beat | Christoph, Alexander Rust | Knechtle, Patrizia | Lepers, Romuald | Rosemann, Thomas; International audience; ''The aims of the study were to [1] investigate the performance trends at the 'Zurich 12-h Swim' in Switzerland from 1996 to 2010; and [2] determine the gender difference in peak performance in ultra-endurance swimming. In total, 113 male and 53 female swimmers competed in this indoor ultra-endurance event while swimming in a heated pool. The number of male participants significantly increased (r(2) = 0.36, P = 0.04) over time while the participation of females remained unchanged (r(2) = 0.12, P = 0.26). In the age group 0.05). The best perform…
