Effects of an incremental maximal endurance exercise stress-induced cortisol on cognitive performance
2019
Exercise; Cognitive functions; Cortisol Ejercicio físico; Funciones cognitivas; Cortisol Exercici físic; Funcions cognitives; Cortisol Objectives: It can be hypothesized that cognitive performance decreases after fatigue protocol when it coincides with the maximum peak of cortisol. The first aim of this study was to elucidate the effects of a single bout of high intensity exercise on behavioural (i.e., attention and memory) and physiological (i.e., salivary cortisol) responses. The second objective was to evaluate the effect of the performance of the cognitive tasks on cortisol levels. Methods: Thirty-four physically active men (at least 5 days/week of physical activity practice) 38.11 (1.5…
Positive effects of an extracellular matrix hydrogel on rat anterior cruciate ligament fibroblast proliferation and collagen mRNA expression
2015
Summary Background/Objective We have previously shown that an extracellular matrix (ECM) bioscaffold derived from porcine small intestine submucosa (SIS) enhanced the healing of a gap injury of the medial collateral ligament as well as the central third defect of the patellar tendon. With the addition of a hydrogel form of SIS, we found that a transected goat anterior cruciate ligament (ACL) could also be healed. The result begs the research question of whether SIS hydrogel has positive effects on ACL fibroblasts (ACLFs) and thus facilitates ACL healing. Methods In the study, ECM-SIS hydrogel was fabricated from the digestion of decellularised and sterilised sheets of SIS derived from αGal-…
Liiketoimintatiedon hallinnan soveltuvuus urheiluorganisaation käyttöön : case AKK Sports Oy
2016
Nykyisessä tietoyhteiskunnassa johtamisen roolin tulisi perustua aiempaa enemmän liiketoimintatietoon, joka on systemaattisempaa ja ennakoivampaa kuin ennen. Tietotarpeiden määrittäminen ja tunnistaminen toimii lähtökohta- na tiedolla johtamisen prosesseissa ja tehokkaan liiketoimintatiedon hallinnan hyödyntämisessä. Liiketoimintatiedon hallinta on toimintaa, jonka avulla orga- nisaatio kerää, analysoi, jakaa ja hyödyntää oman toimintansa kannalta merkit- tävää liiketoimintatietoa. Kypsyysmallien tarkoitus on tuottaa organisaatiosta analyyttinen arviointi, joka toimii tukipilarina organisaation kehittymisproses- sissa. Kypsyysmalleja käytetään kuvaamaan, selittämään ja arvioimaan organi- sa…
1,4-Dihidropiridīnu atvasinājumu nanodaļiņu toksiskuma novērtējums mikroorganismos
2017
1,4 Dihidropiridīnu (1,4 DHP) atvasinājumi ir plaša organisko vielu grupa, kurā arvien tiek sintezēti jauni savienojumi ar plašām pielietojuma iespējām. Jauno savienojumu toksicitātes raksturojums ir nepieciešams, lai paredzētu to pielietojuma iespējas un novērtētu to iedarbību uz vidi un dzīvajiem organismiem. Darbā pielāgota universāla un efektīva atšķaidījumu metode, lai noteiktu deviņu katjono amfifilo 1,4 DHP atvasinājumu toksicitātes robežkoncentrācijas sešām baktērijām un vienam raugam. Papildus noteikta 1,4 DHP atvasinājumu ietekme uz iekššūnas ATP daudzumu, skābekļa patēriņa ātrumu un etīdija bromīda transportu šūnās. Noskaidrojot toksicitātes robežkoncentrācijas un gūstot ieskatu …

Specific muscle-tendon architecture in elite Kenyan distance runners
2013
The Achilles tendon moment arm (MA_AT) and foot lever ratio (FLR) can play important roles for force production and movement economy during locomotion. This notion has become more relevant, and suggestion has been given that the Kenyan runners belonging to the world elite would have specific anatomical, mechanical, and functional properties in their lower limbs and that this feature could be responsible for their high running economy. The present study aimed to characterize the AT of elite Kenyan distance runners as compared with Japanese ones, and to examine the potential relationship with their running performance. Ultrasonography was used to measure AT cross-sectional area and AT soleus …
Medial gastrocnemius muscle and tendon interaction during gait in typically developing children and children with cerebral palsy
2020
1. IntroductionEfficient gait is dependent on optimal interaction between musclesand tendons [1]. Pathological changes in the extensibility of the MGmuscle fascicles, whole muscle-belly and Achilles tendon have beenreported in children with spastic cerebral palsy (CP) [2]. Studying therelative length of these tissues during gait can improve our understandingof their dynamics and, inferably, the control strategies used inCP. In-vivo dynamic ultrasound imaging has been used to visualise theinteraction between the MG muscle and tendon during 3D gait analysis.However, most studies combined ultrasound imaging of one variable(either fascicles or muscle-belly and tendon) with some form ofmusculosk…
The influence of physical activity during youth on structural and functional properties of the Achilles tendon
2013
Achilles tendinopathy is a highly prevalent sports injury. Animal studies show a growth response in tendons in response to loading in the immature phase but not after puberty maturation. The aim of this investigation was to examine the structural and material properties in long distance runners who were either physically active (HAY) or inactive (LAY) in young age. Twelve men in HAY group and eight men in LAY group participated. Structural, functional, and biochemical properties of Achilles tendon were estimated from magnetic resonance imaging, ultrasound video recordings, mechanical tests, and tendon biopsies, respectively. There was no difference between the groups with respect to tendon …
5 Effects Of Low-intensity Concentric Combined With Blood Flow Restriction On Achilles Tendon
2014
Introduction Weight training is a useful tool in order to achieve muscular hypertrophy. However, the American College of Sports Medicine (ACSM) recommends intensities of 70% of one repetition maximum (1-RM). Those intensities may not be suitable for everyone because of the high mechanical stresses placed upon the joints [Loenneke, 2012]. Nowadays, it is common to combine low-intensity exercise (20–30% 1-RM) with blood flow restriction (BFR) because of the beneficial effects in increased muscular strength, hypertrophy, localised endurance and cardiorespiratory endurance [Pope, 2013]. Despite there is not many papers about the beneficial of this training, it is know that the tendon suffers so…
