M1_Microfluidics_for_CNT

2018

High-frequency droplet production in step-emulsification microfluidic device. The abrupt change in channel cross section causes creation of the droplets. The closely-packed droplets automatically order in hexagonal pattern.

M5_Microfluidics_for_CNT

2018

The features of the sorting junction. Pressure balancer helps to equilibrate the pressure difference created by the presence of a droplet. The transition from shallow to deep channel mediates the transition from free to confined regime. The droplets are separated in the sorting junction according to the flow rate ratio.

M8_Microfluidics_for_CNT

2018

A comparation of two sorting strategies. While the shallow channel guides the droplets more precisely to the sorting point, the confined droplets are more vulnerable to coalescence and break-up. The deep channel lowers the positioning precision, however, the droplets are more stable.

Fuerza muscular inspiratoria dinámica y aptitud cardiorrespiratoria en función de edad y sexo

2020

espanolObjetivo: Analizar la relacion entre fuerza inspiratoria y aptitud cardiorrespiratoria en un grupo de adultos mayores sanos y entrenados, atendiendo a edad y sexo. Metodo: Estudio descriptivo, de corte transversal y prospectivo. De los 153 participantes en el programa de entrenamiento multicomponente EFAM-UV© y mayores de 60 anos, 87 fueron evaluados de composicion corporal, presion arterial, saturacion de oxigeno, fuerza inspiratoria maxima y test de 6 minutos marcha. Como criterios de exclusion: fumador, padecer/haber padecido enfermedad respiratoria, cardiaca, neuromuscular o de la caja toracica, padecer/haber padecido deterioro cognitivo y/o llevar protesis dental. 67 adultos may…

Directrices científicas de ejercicio para personas adultas con lesión medular: proceso de desarrollo, resultados y recomendaciones para su implementa…

2020

espanolEl presente articulo describe el proceso sistematico seguido para desarrollar unas directrices cientificas de ejercicio para personas con lesion medular, asi como sus resultados. Para mejorar la condicion fisica, las personas adultas con lesion medular deben realizar al menos 20 minutos de ejercicio aerobico de intensidad moderada-vigorosa, dos veces por semana, combinados con tres series de ejercicios de fuerza de intensidad moderada-vigorosa por cada grupo muscular con funcionalidad, dos veces por semana. Para mejorar la salud cardiometabolica, se sugiere que las personas adultas con lesion medular realicen al menos 30 minutos de ejercicio aerobico de intensidad moderada-vigorosa t…

Dare to jump: The effect of the new high impact activity SuperJump on bone remodeling. A new tool to maintain fitness during COVID-19 home confinement

2021

SuperJump is a high impact activity performed on an elastic trampoline that mixes aerobic and anaerobic exercises already proposed as home-based activity for preventing a sedentary lifestyle. We determined in a randomized controlled trial whether 20 weeks of SuperJump activity would promote bone formation and reduce resorption in eumenorrheic women. Twenty-four women were randomized to a non-exercise group (control group) or an exercise group that performed SuperJump activity three times a week for 20 weeks. Blood samples were collected in both groups at baseline and at the end of the 20 weeks and compared within and between the groups for C-terminal telopeptide (CTX), a marker of bone reso…

Force-, power-, and elasticity-velocity relationships in walking, running, and jumping

1980

Ground reaction forces and mechanical power were investigated when the subjects walked normally, while they were racing or running at four speeds, and when they performed the running long jump take-off. In addition, the apparent spring constants of the support leg in eccentric and concentric phases were investigated at the four running speeds, during the running long jump take-off, and in the triple jump. Six club level track and field athletes, four national level long jumpers, and six national level triple jumpers took part in the study. Cinematographic technique and a mathematical model of hopping (Alexander and Vernon 1975) were employed in the analysis. Force and power values were foun…

Réponses cardiovasculaires lors de la distribution du courrier postal avec un vélo à assistance électrique

2010

Cette etude a evalue les reponses cardiovasculaires lors de la distribution du courrier postal. Vingt-deux facteurs ont ete testes sur deux journees de travail, l’une realisee avec un velo electrique (VE), l’autre avec un velo traditionnel (VT). Les resultats ont montre une diminution significative (p < 0,05) de la frequence cardiaque moyenne avec l’utilisation d’un VE (90 ± 15 bpm) en comparaison d’un VT (94 ± 14 bpm), dont l’importance semble dependante du type de tournee realisee (type Pavillon vs. type Centre-ville). La duree de travail (≈ 660 min) et la depense energetique (≈ 330 Kcal) n’etaient pas affectees par le type de velo utilise. Le VE semble donc etre une alternative interessa…

Stacking et discrimination : le cas de deux études en contexte virtuel

2013

Resume A partir de la theorie du stacking, cette recherche vise a questionner les processus de discrimination mis en œuvre (couleur de peau et genre) en sport. Plus precisement, les deux etudes proposees montrent l’existence de biais de placement des joueurs, au basketball et au football. La premiere etude met en evidence une surrepresentation des basketteurs noirs aux postes non centraux et une surrepresentation des basketteurs blancs aux postes centraux (racial stacking). La deuxieme etude met en evidence une surrepresentation des footballeuses aux postes non centraux et une surrepresentation des footballeurs aux postes centraux (gender stacking). Les processus sont discutes en termes de …

Modèles internes et imagerie motrice

2013

L’imagerie motrice (IM) est la representation mentale d’une action, sans production concomitante de mouvement. Les techniques d’enregistrement et de stimulation du systeme nerveux central ont montre au cours de ces trois dernieres decennies que l’IM partageait des sites d’activation corticale et sous-corticale avec l’action reellement executee. Cette similitude, sans pour autant etre parfaitement identique, se retrouve aussi dans les activations peripheriques nerveuses et vegetatives. De plus, le travail mental est un element facilitateur de l’apprentissage, favorisant l’amelioration de la performance. Certains courants de pensee attribuent les mecanismes sous-jacents de l’IM et les benefic…
