Stress Assessment of Vestibular Endurance Training for Civil Aviation Flight Students Based on EEG

2021

AbstractObjectiveThe main goal of our study is to clarify the EEG characteristics of the stress response caused by vestibular endurance training under the real conditions.MethodsTen pilot trainees received a series of acute anti-vertigo training stimulations on the rotary ladder while recording electroencephalographic data (64 electrodes). Afterwards, the subject’s anti-vertigo ability was tested for the best performance after 1 month of training, and verifying whether it is relating to the EEG signals we collected before.Results(1) The absolute power ofαwaves in the C3 and C4 regions is same as the difference between 1 min before and 2 min after stimulation, and their activity is enhanced …

Quale tipo di allenamento fa bene al cuore?

2006

L’antica evidenza che i cuori dei così detti animali “atletici” (lepri, ratti selvaggi) abbiano una più alta densità capillare rispetto a quelli di specie più sedentarie con un simile peso corporeo (conigli, ratti di laboratorio) supporta l’ipotesi che sedute di allenamento ripetute nel tempo siano in grado di aumentare la vascolarizzazione del miocardio. Il rimodellamento vascolare capillare del cuore in risposta all’esercizio fisico è noto dipendere dalla sezione e dall’allocazione dei vasi lungo l’albero coronarico, dai fattori molecolarie meccanici, dall’età dei soggetti e dal tipo di programma di allenamento. Un lungo allenamento di endurance, in particolare, sembra essere il modello e…

Effects of nine months resistance training on cycling economy in elderly men and women

2016

The aging process, along with the lifestyle, is associated with loses in functional capacity and independence due to factors such as decreases in muscle mass, strength, and aerobic capacity, among others. Resistance training (RT) has been shown to induce strength and muscle size gains in the elderly. Improvements in maximal endurance capacity have been shown in some studies, while others have found no change. The purpose of the present study was to examine the effects of RT on the cycling economy in the elderly. A group of 47 older men and women (65-75 years) participated in the study. Subjects were assigned into one of two groups: 1) a training group performing 3 months of RT focusing on l…

Mental Fatigue Effects on the Produced Perception of Effort and Its Impact on Subsequent Physical Performances.

2022

The purpose of this study was to investigate the relationship between mental fatigue induced by a demanding cognitive task and impaired physical performance in endurance due to a higher perception of effort. A total of 12 healthy adults and volunteers, who had previously practiced endurance activities for 4 to 8 h per week, performed a one-hour cognitive task involving either the process of response inhibition (Stroop task) or not (visualization of a documentary as control task), then 20 min of pedaling on a cycle ergometer at a constant perception of effort while cardio-respiratory and neuromuscular functions were measured. The Stroop task induces subjective feelings of mental fatigue (vig…

Analysis of ultra-triathlon performances

2011

Romuald Lepers1, Beat Knechtle2,3, Patrizia Knechtle2, Thomas Rosemann2 1INSERM U887, Faculty of Sport Sciences, University of Burgundy, Dijon, France; 2Institute of General Practice and Health Services Research, University of Zurich, Switzerland; 3Gesundheitszentrum St Gallen, St Gallen, Switzerland Abstract: Despite increased interest in ultra-endurance events, little research has examined ultra-triathlon performance. The aims of this study were: (i) to compare swimming, cycling, running, and overall performances in three ultra-distance triathlons, double Ironman distance triathlon (2IMT) (7.6 km swimming, 360 km cycling, and 84.4 km running), triple Ironman distance triathlon (3IMT) (11.…

Risk of Low Energy Availability, Disordered Eating, Exercise Addiction, and Food Intolerances in Female Endurance Athletes

2022

Relative energy deficiency in sport (RED-S) is a complex syndrome describing health and performance consequences of low energy availability (LEA) and is common among female endurance athletes. Various underlying causes of LEA have been reported, including disordered eating behavior (DE), but studies investigating the association with exercise addiction and food intolerances are lacking. Therefore, the aim of this cross-sectional study was to investigate the association between DE, exercise addiction and food intolerances in athletes at risk of LEA compared to those with low risk. Female endurance athletes, 18–35 years, training ≥5 times/week were recruited in Norway, Sweden, Ireland, and Ge…

Participation and performance trends in ultra-triathlons from 1985 to 2009.

2011

International audience; We examined the changes in participation and performance trends in ultra-triathlons, from the Double Iron (7.6 km swimming, 360 km cycling, 84.4 km running) to the Deca Iron (38 km swimming, 1800 km cycling, 422 km running), between 1985 (first year of a Double Iron) and 2009 (25 years). The mean finish rate for all distances and races was 75.8%. Women accounted for ∼8-10% of the ultra-triathlons starters. For Double and Triple Iron, the number of finishers per year increased, from 17 to 98 and from 7 to 41, respectively. In the Deca Iron, the finishers per race have remained <20 since the first event was held, up to 2009. Concerning World best performances, the men …
