Aging and strength training influence knee extensor intermuscular coherence during low- and high-force isometric contractions
2019
Aging is associated with reduced maximum force production and force steadiness during low-force tasks, but both can be improved by training. Intermuscular coherence measures coupling between two peripheral surface electromyography (EMG) signals in the frequency domain. It is thought to represent the presence of common input to alpha-motoneurons, but the functional meaning of intermuscular coherence, particularly regarding aging and training, remain unclear. This study investigated knee extensor intermuscular coherence in previously sedentary young (18–30 years) and older (67–73 years) subjects before and after a 14-week strength training intervention. YOUNG and OLDER groups performed maximu…
Resistance Training Load Effects on Muscle Hypertrophy and Strength Gain : Systematic Review and Network Meta-analysis
2020
PURPOSE This study aimed to analyze the effect of resistance training (RT) performed until volitional failure with low, moderate, and high loads on muscle hypertrophy and muscle strength in healthy adults and to assess the possible participant-, design-, and training-related covariates that may affect the adaptations. METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases were searched. Including only studies that performed sets to volitional failure, the effects of low- (>15 repetitions maximum (RM)), moderate- (9-15 RM), and high-load (≤8 RM) RTs were examined in healthy adults. Networ…
Physical activity on days with and without soccer practice in 12-13-year-old boys
2019
Introduction: Majority of children are unable to meet the recommended 60min of daily moderate to vigorous physical activity (MVPA). Even participation into organized sport may not guarantee that recommended amount of activity is reached. Objectives: Purpose of this study was to examine the amount and intensity of physical activity (PA) on days with and without practices and to find out whether daytime PA preceding soccer practice is associated with certain practice-time PA intensity level. Methods: Daily light, moderate and vigorous PA of 18 boys between 12 and 13 years of age engaged in soccer was measured for 9 days with and without soccer practices with wrist-worn Polar A300 activity met…
Effects of Combined Strength and Endurance Training on Body Composition, Physical Fitness, and Serum Hormones During a 6-Month Crisis Management Oper…

Pihlainen, K, Kyröläinen, H, Santtila, M, Ojanen, T, Raitanen, J, and Häkkinen, K. Effects of combined strength and endurance training on body composition, physical fitness, and serum hormones during a 6-month crisis management operation. J Strength Cond Res XX(X): 000-000, 2020-Very few studies have examined the impact of training interventions on soldier readiness during an international military operation. Therefore, the present study investigated the effects of combined strength and endurance training on body composition, physical performance, and hormonal status during a 6-month international military deployment consisting of typical peacekeeping tasks, e.g., patrolling, observation, a…
Maximum Dynamic Lower-Limb Strength Was Maintained During 24-Week Reduced Training Frequency in Previously Sedentary Older Women.
2018
Walker, S, Serrano, J, and Van Roie, E. Maximum dynamic lower-limb strength was maintained during 24-week reduced training frequency in previously sedentary older women. J Strength Cond Res 32(4): 1063-1071, 2018-There is little study into the effects of reducing strength training below the recommended twice weekly frequency, particularly in older women, despite the possibility that individuals will encounter periods of reduced training frequency. The purpose of the present study was to determine the effects of a period of reduced training frequency on maximum strength and muscle mass of the lower limbs in comparison with the recommended training frequency of twice per week. After an initia…
Increased fascicle length but not patellar tendon stiffness after accentuated eccentric-load strength training in already-trained men
2020
Purpose This study examined whether additional external load during the eccentric phase of lower limb strength training exercises led to greater adaptations in knee extensor strength, muscle architecture, and patellar tendon properties than traditional concentric–eccentric training in already-trained men. Methods Twenty-eight men accustomed to strength training were randomized to undertake 10 weeks of supervised traditional (TRAD) or accentuated eccentric loading (AEL) or continue their habitual unsupervised (CON) strength training. TRAD and AEL trained 2∙week−1 with a six-repetition maximum (RM) session and a ten-RM session. TRAD used the same external load in both concentric and eccentric…
Duurisävellajin epäkonventionaalinen käyttö musiikillisen emootion välityksessä
2011
Tutkimuksessa tarkasteltiin, miten duurisävellajissa menevä musiikki voi välittää melankolisen tai surullisen emootion. Kysymyksenasettelulla pyrittiin kyseenalaistamaan yksinkertaistava emootiokonventio duurisävellajin iloisuudesta ja kiinnitettiin huomiota perusemootiokategorisoinnin (ilo-suru-dikotomia) riittämättömyyteen kuvaamaan musiikillista emootionvälitystä. Tutkimuksessa tarkasteltiin perinteisen ilo-suru perusemootiokategorisoinnin välissä olevia emootioita kuten nostalgia ja melankolia. Epäkonventionaalista sävellajin käyttöä pyrittiin selittämään soveltamalla Brunswikin linssimallia musiikilliseen emootionvälitykseen. Tämän lisäksi Balkwillin ja Thompsonin esittelemä kulttuurit…
Nie ma takiej wiedzy, która jest ostateczna. Każda stanowi przedsionek prowadzący do nowych obszarów niewiedzy. "Götz i Meyer" Davida Albahariego
2018
This article’s aim is to analyze David Albahari’s Götz and Meyer as the only Serbian literary text whose main theme is the extermination of the native Jews. The recurring key-word of the analysis is the notion of void, which appears both on the plot level and a more metaphorical one that connotes a less perceptible meaning of Albahari’s prose which can be summarized as a conviction about the insufficient memory of the Holocaust in Serbia. The main aim of this paper is to demonstrate what method Albahari employs to build his story. Consequently, juxtaposing history (ostensibly objective, linked with the order of reason) with fiction proves to be here of the utmost importance. It demonstrates…
