IS HYPOXIA A TRAINING STIMULUS FOR ENDURANCE ATHLETES’ PERFORMANCE? A BRIEF REVIEW.
2012
ABSTRACT: Background. There is increasing popularity among elite athletes to endorse altitude training to enhance performance levels. Altitude training may be used for enhanced performance at sea level, or to acclimatise to a competition at altitude. Enhancement of muscle oxidative capacity, muscle glycolytic capacity, skeletal muscle oxygenation, oxygen transport and storage within the muscle, and hormonal regulation have been reported with altitude training. Aim. The aim of this review is to analyse current knowledge on hypoxic training and its possible relation to enhanced endurance performance. This paper will consider factors including the process of enhanced sea level performance in r…
The metabolic responses to electrical pulse-induced contractions in C2C12 myotubes are greater in high glucose medium
2021
Osaa liikunnan terveyshyötyjen mekanismeista on vaikeaa tutkia ihmisillä tai koe-eläimillä. Viljeltyjen C2C12 myotuubien sähköpulssistimulaatiolla (EPS, engl. electrical pulse stimulation) voidaan mallintaa lihassupistuksia ja liikuntaa in vitro –olosuhteissa. EPS:n vaikutusta C2C12 myotuubien aineenvaihduntaan ei kuitenkaan tunneta tarkasti. Lisäksi C2C12 myotuubeja viljellään yleensä korkeassa ei-fysiologisessa 25 mM glukoosipitoisuudessa, mikä voi vaikuttaa EPS-vasteisiin. Tässä tutkimuksessa C2C12 myotuubeja sähköpulssistimuloitiin 24 tunnin ajan sekä matalan 5.5 mM (MG) että korkean 25 mM (KG) glukoosipitoisuuden olosuhteissa, ja aineenvaihduntatuotteiden konsentraatiot analysoitiin se…
Complete Genome Sequence of a New Ruminococcaceae Bacterium Isolated from Anaerobic Biomass Hydrolysis
2018
ABSTRACT A new Ruminococcaceae bacterium, strain HV4-5-B5C, participating in the anaerobic digestion of grass, was isolated from a mesophilic two-stage laboratory-scale leach bed biogas system. The draft annotated genome sequence presented in this study and 16S rRNA gene sequence analysis indicated the affiliation of HV4-5-B5C with the family Ruminococcaceae outside recently described genera.
Biochemical methane potential (BMP) of solid organic substrates: evaluation of anaerobic biodegradability using data from an international interlabor…
2011
Background: This paper describes results obtained for different participating research groups in an interlaboratory study related to biochemical methane potential (BMP). In this research work, all experimental conditions influencing the test such as inoculum, substrate characteristics and experimental conditions were investigated. The study was performed using four substrates: three positive control substrates (starch, cellulose and gelatine), and one raw biomass material (mung bean) at two different inoculum to substrate ratios (ISR). Results: The average methane yields for starch, cellulose, gelatine and mung bean at ISR of 2 and 1 were 350 ± 33, 350 ± 29, 380 ± 42, 370 ± 36 and 370 ± 35 …
UNA PANORAMICA SULL’ANEMIA SIDEROPENICA NEGLI ATLETI/AN OVERVIEW ON IRON DEFICIENCY ANEMIA IN ATHLETES
2012
Diversi studi in letteratura riportano come la capacità prestativa degli atleti di endurance sia fortemente compromessa in seguito all’insorgenza di anemia sideropenica. Questa, infatti, è una delle più importanti cause di overtraining negli atleti che pratica attività sportive di lunga durata come: la maratona, la marcia, il ciclismo. Tra le diverse cause di anemia ferropriva ricordiamo: una dieta inadeguata a soddisfare le richieste di ferro dell’organismo, una riduzione dell’assorbimento di ferro a livello intestinale e/o un’eccessiva perdita di questo elemento da parte dell’atleta. Il controllo periodico tramite analisi ematochimiche, metaboliche e funzionali potrebbe essere un valido s…
The Role of Physical Exercise and Rehabilitative Implications in the Process of Nerve Repair in Peripheral Neuropathies: A Systematic Review
2023
Background: The various mechanisms involved in peripheral nerve regeneration, induced by exercise and electrical nerve stimulation, are still unclear. Objective: The aim of this review was to summarize the influence of physical exercise and/or electrical stimulation on peripheral nerve repair and regeneration and the variation of impact of intervention depending on timing, as well as kind and dosage of the intervention. A literature survey was conducted on PubMed, Scopus, and Web of Science, between February 2021 to July 2021, with an update in September 2022. Methodology: The literature search identified 101,386 articles with the keywords: “peripheral nerve” OR “neuropathy” AND “sprouting”…
2016 Antiaging Medicine
2016
• The factors best demonstrated to delay aging are fruit and vegetables, exercise, not smoking, drinking one or two glasses of alcohol daily, and fish consumption. • Vitamin D replacement, in persons with low 25[OH] vitamin D levels, decreases hip fractures, improves muscle strength, enhances function, and decreases mortality. • Antiaging medicine has been hijacked by charlatans who promote unproven or dangerous remedies to a naïve aging public. • Too often animal studies that produce longevity are directly ap-plied to humans before appropriate clinical trials have been carried out. • There is no evidence that hormones or megadoses of vitamins prolong life. • Numerous products of varying qu…

Knee arthroscopy and exercise versus exercise only for chronic patellofemoral pain syndrome: a randomized controlled trial
2007
BACKGROUND: Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS). As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS. METHODS: A total of 56 patients with chronic PFPS were randomized into two treatment groups: an arthroscopy group (N = 28), treated with knee arthroscopy and an 8-week home exercise program, and a control group (N = 28), treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and function …
Fonētisko traucējumu mazināšana vidējā pirmsskolas vecuma bērniem artikulācijas vingrinājumos
2022
Ar literatūras izpēti sākas jebkurš pētnieciskais darbs. (Albrehta, 1998, 9). Darba autore izvēlētajam darba tematam piemeklēja un aplūkoja daudzus literatūras avotus, lai sekmīgi veiktu pētījumu, kuri vienmēr balstās uz teorētiskiem uzskatiem, un kā tiks veikts arī šajā diplomdarbā. Darba autore 1. nodaļā veic teorētiskās literatūras analīzi, lai izzinātu noteiktā vecumposma (4-5 gadu jauna) bērna attīstības raksturojumu veselumā. 2.nodaļā autore pēta un analizē literatūru par runas traucējumu rašanās cēloņiem, izpausmēm un fonētisko traucējumu raksturojumu. Balstoties uz vairāku autoru darbiem, 3.nodaļā tika veikta izpēte par artikulācijas aparātu un tā vingrinājumiem, un artikulācijas ap…
