Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…

Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?
2022
Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…

Force transmission and interactions between synergistic muscles
2023
The classical view of muscles as independent motors has been challenged over the past decades. An alternative view has emerged in which muscles are not isolated but embedded in a three-dimensional connective tissue network that links them to adjacent muscles and other non-muscular structures in the body. Animal studies showing that the forces measured at the distal and proximal ends of a muscle are not equal have provided undisputable evidence that these connective tissue linkages are strong enough to serve as an extra pathway for muscular force transmission. In this historical review, we first introduce the terminology and anatomy related to these pathways of muscle force transmission and …
Rhythmic Memory Consolidation in the Hippocampus
2022
Functions of the brain and body are oscillatory in nature and organized according to a logarithmic scale. Brain oscillations and bodily functions such as respiration and heartbeat appear nested within each other and coupled together either based on phase or based on phase and amplitude. This facilitates communication in wide-spread neuronal networks and probably also between the body and the brain. It is a widely accepted view, that nested electrophysiological brain oscillations involving the neocortex, thalamus, and the hippocampus form the basis of memory consolidation. This applies especially to declarative memories, that is, memories of life events, for example. Here, we present our vie…
Laulaminen puhehäiriöiden kuntoutuksessa
2014
Kandidaatintutkielmani on tarkka kuvaus äänentuottoprosessista ja siinä ilmenevistä vaikeuksista. Tutkielmani alkuosioissa perehdyn laulun ja puheen äänentuoton neurologiseen ja fysiologiseen prosessiin ja äänentuottoelimistön toimintaan. Lisäksi selvitän laulun ja puheen yhtäläisyydet ja eroavaisuudet, jotka toimivat osittain perusteluina puhehäiriöiden musiikilliselle ja laululliselle kuntoutukselle. Selvitän eri puhehäiriöiden aiheuttajia ja kuvaan niiden oirekuvia, sillä erilaisten puhehäiriöiden kuntouttamisessa tulee ottaa huomioon millaisesta puhehäiriöstä on kyse ja millaisia terapiamalleja niihin tulee soveltaa. Määrittelen ”lauluterapia”-termin musiikkiterapian ja puheterapian väl…
