Do Obese Children Achieve Maximal Heart Rate during Treadmill Running?

2019

Objective: Maximal heart rate (HR) is commonly defined as the highest HR obtained during a progressive exercise test to exhaustion. Maximal HR is considered one of the criteria to assess maximum exertion in exercise tests, and is broadly used when prescribing exercise intensity. The aim of the present study was to compare peak HR measurements during maximal treadmill running and active play in obese children and adolescents. Design: Comparison of peak heart rate during active play vs. maximal treadmill running in 39 (7&ndash

Differences in myoelectric activity of the lumbar muscles between recurrent and chronic low back pain: a cross-sectional study

2021

Abstract Background Altered lower back muscle activity is proposed as a contributing factor to the reoccurrence and chronicity of low back pain (LBP). This study compared lumbar muscle activity during trunk extension in patients with continuous chronic LBP (CLBP), non-continuous CLBP, recurrent LBP (RLBP) and healthy subjects. Methods In 75 subjects (16 continuous CLBP, 15 non-continuous CLBP, 23 RLBP, 21 healthy controls), surface electromyographic (EMG) activity of the lumbar erector spinae (ES), multifidus (MF), latissimus dorsi (LD) and gluteus maximus (GM) was recorded during the concentric, holding and eccentric phase of a modified Biering Sorenson exercise. Results Continuous CLBP pa…

Muscle cramping in the marathon: dehydration and electrolyte depletion vs. muscle damage

2020

Martinez-Navarro, I, Montoya-Vieco, A, Collado, E, Hernando, B, Panizo, N, and Hernando, C. Muscle Cramping in the marathon: Dehydration and electrolyte depletion vs. muscle damage. J Strength Cond Res XX(X): 000-000, 2020-Our aim was to compare dehydration variables, serum electrolytes, and muscle damage serum markers between runners who suffered exercise-associated muscle cramps (EAMC) and runners who did not suffer EAMC in a road marathon. We were also interested in analyzing race pacing and training background. Nighty-eight marathoners took part in the study. Subjects were subjected to a cardiopulmonary exercise test. Before and after the race, blood and urine samples were collected and…

MYOCARDIAL POTENCY OF AQUEOUS EXTRACT OF HARUNGANA MADAGASCARIENSIS STEM BARK AGAINST ISOPROTERENOL-INDUCED MYOCARDIAL DAMAGE IN RATS

2018

Objectives: The present study was undertaken to evaluate the effects of Harungana madagascariensis on electrocardiographical, biochemical and histopathological changes in isoproterenol (ISO)-induced myocardial infarction in rats. Methods: Male Wistar albino rats were randomly divided and treated with the aqueous extract of Harungana madagascariensis stem bark (AEHM, 200 and 400 mg/kg per os), or normal saline or vitamin E for 7 days with concomitant administration of ISO (85 mg/kg, subcutaneously) on 8th and 9th days, at 24 h interval. Results: The ISO injections to the rats caused cardiac dysfunction evidenced by a marked (P<0.01) elevation in ST-segment, a reduction in R wave amplitude (P…

Risk-Reducing Gynecological Surgery in Lynch Syndrome: Results of an International Survey from the Prospective Lynch Syndrome Database.

2020

Purpose: To survey risk-reducing hysterectomy and bilateral salpingo-oophorectomy (BSO) practice and advice regarding hormone replacement therapy (HRT) in women with Lynch syndrome. Methods: We conducted a survey in 31 contributing centers from the Prospective Lynch Syndrome Database (PLSD), which incorporates 18 countries worldwide. The survey covered local policies for risk-reducing hysterectomy and BSO in Lynch syndrome, the timing when these measures are offered, the involvement of stakeholders and advice regarding HRT. Results: Risk-reducing hysterectomy and BSO are offered to path_MLH1 and path_MSH2 carriers in 20/21 (95%) contributing centers, to path_MSH6 carriers in 19/21 (91%) and…

Concept of an extracellular regulation of muscular metabolic rate during heavy exercise in humans by psychophysiological feedback.

1996

Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but al…

Ētikas diskursi par "oligarhu sarunām" un to publicēšanu Latvijas latviešu valodā rakstošajos medijos

2018

“Oligarhu sarunu” publicēšana žurnālā “Ir” 2017. gada 15. jūnijā Latvijas publiskajā telpā aktualizēja diskusiju par sarunās iesaistīto pušu ētisko atbildību šajā notikumā. Pētījuma “Ētikas diskursi par "oligarhu sarunām" un to publicēšanu Latvijas latviešu valodā rakstošajos medijos” mērķis ir atklāt ētikas diskursus ziņu portālu Irir.lv, NRA.lv, Diena.lv, LA.lv publikācijās laika periodā no 2017. gada 15. jūnija līdz 20. jūlijam. Pētījuma jautājums ir – kādi ētikas diskursi tiek veidoti Irir.lv, NRA.lv, Diena.lv, LA.lv publikācijās par “oligarhu sarunām” un to publicēšanu? Darba teorētiskajā daļā apzināts ētikas jēdziens un teorijas, lai pēc tam, izmantojot kvantitatīvās kontentanalīzes u…

Vārda brīvība ir neatņemama Eiropas Savienības pamatvērtība, kas ir nostiprināta Eiropas Savienības dibināšanas līgumos un praktiski visos cilvēktiesību dokumentos, kas tai ir saistoši. Vārda brīvība aptver ikvienu Eiropas Savienības tiesību subjektu – gan juridiskas, gan fiziskas personas. Mūsdienās dalīties ar informāciju un pilnvērtīgi izmantot piešķirtās tiesības uz vārda brīvību ir vieglāk kā jebkad agrāk pasaules vēsturē. Lielu nozīmi tam piešķir ne tikai straujā tehnoloģiskā attīstība, bet arī Eiropas Savienības tiesību aktos nostiprinātās vērtības – informācijas dažādība un mediju plurālisms. Lai arī tā ir brīnišķīga iespēja, dzīvot tādā vidē, kur katrs tiesību subjekts pats var izv…

COMPARAZIONE DEI PROFILI METABOLICI DI VARIETÀ DI CILIEGIO DOLCE (Prunus avium L.) MEDIANTE TECNICHE DI METABOLOMICA UNTARGETED

La diffusione di cultivar altamente produttive ha influito negativamente sulla tutela dell’agro-biodiversità di Prunus avium L. determinando disinteresse nei confronti di varietà meno produttive ma meritevoli di attenzione per il valore delle loro caratteristiche organolettiche e del relativo patrimonio genetico. Il mondo scientifico ha mostrato interesse nei confronti di tale tematica e ha condotto azioni di conservazione in situ ed ex situ per preservare il germoplasma ancora esistente. La presente ricerca analizza l’agrobiodiversità del ciliegio dolce in relazione alla diversa composizione metabolomica dei frutti, espressione del genotipo che le caratterizza. L’attività di ricerca svolta…

"Carmen, mene ja taiteile maailman lankoja pitkin" : Saila Susiluodon Carmen metalyyrisenä allegoriana

2012

Pro gradu -tutkielmassani luen Saila Susiluodon teosta Carmen (2010) metalyyrisenä allegoriana: narratiivisena vertauskuvallisena jatkumona, joka kertoo runoudesta ja omasta rakentumisestaan. Lähtökohtana on ajatus,että runojen nimikkopuhujana toimiva Carmen on eräänlainen runon ruumiillistuma. Tarkastelen, mitä metalyyrinen allegoria paljastaa runon luonteesta sekä suhteesta runoilijaan ja muihin taiteisiin. Tutkin, mikä on runon tehtävä ja paikka maailmassa ja miten ne kytkeytyvät runon puhujan sukupuoleen. Samalla pyrin havainnoimaan, millaisin keinoin metalyyristä allegoriaa rakennetaan. Luentani teoreettisena viitekehyksenä on metalyriikka, johon muut keskeiset käsitteet suhteutetaan. …
