Effect of the Game Design, the Goal Type and the Number of Players on Intensity of Play in Small-Sided Soccer Games in Youth Elite Players
2015
Abstract The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not f…

Is It Easy to Synchronize Our Minds When We Are Forced to Cooperate?
2019
There is increasing scientific interest in elucidating the biological mechanisms underlying cooperative behaviors. Humans have developed a high degree of complexity in their cooperativity, which has been defined as hyper-cooperativity. An interesting biological marker to study how two individuals are emotionally linked when they cooperate is their psychophysiological synchronization (the overlapping of signals as indicators of Autonomous Nervous System activation). Hence, the main aim of this study was to explore participants&rsquo
Five insights from the Global Burden of Disease Study 2019
2020
The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a rules-based synthesis of the available evidence on levels and trends in health outcomes, a diverse set of risk factors, and health system responses. GBD 2019 covered 204 countries and territories, as well as first administrative level disaggregations for 22 countries, from 1990 to 2019. Because GBD is highly standardised and comprehensive, spanning both fatal and non-fatal outcomes, and uses a mutually exclusive and collectively exhaustive list of hierarchical disease and injury causes, the study provides a powerful basis for detailed and broad insights on global health trends and emerging challenges. GBD …
Acute Cardiovascular Responses after a Single Bout of Blood Flow Restriction Training.
2018
Different types of exercise might produce reductions in blood pressure (BP). One physiological mechanism that could explain the lowering adaptation effect on BP after an exercise program is an improved in baroreflex control of muscle sympathetic nerve activity. Consequently, exploring the different methods of training and their post-exercise hypotension (PEH) becomes of interest for healthcare providers. Recently, it has been suggested that blood flow restriction training (BFR) can generate PEH. The aim of this study was to determine the acute response on cardiovascular variables after low intensity resistance training with BFR in normotensive subjects. Twenty-four male (24.38±3.88 years) p…
Negative responses to strategic innovation, a case study of record labels facing streaming
2021
Record labels are organizations in charge of phonographic production at the interface between musicians and the audience. Since the arrival of digital technologies such as the mp3 and the Internet, record labels have had to adapt to several changes: wider distribution channels, dematerialized competitors, customers’ demands for free music, more ephemeral cooperation. Specifically, streaming platforms like Spotify brought a major change known as a strategic innovation. A strategic innovation is a strong change that overturns all previously established values in the sector (renewal of values attached to the product, values attached to the customer relationship and power relations). However, f…
Serum hormone concentrations and physical performance during concurrent strength and endurance training in recreational male and female endurance run…
2011
To investigate the effects of concurrent strength and endurance training on physical performance and serum hormone levels a total of 32 recreational endurance runners were trained for 18 weeks. Subjects were divided into four training groups separated by the strength training mode and gender. The groups were women’s and men’s combined maximal and explosive strength training group (WME; n=9 and MME; n=9), and women’s and men’s muscle endurance strength training group (WE; n= 8 & ME; n=8). The training was executed in three consecutive periods (I; 10 weeks, II; 4 weeks and III; 4 weeks). The endurance training in all groups was low-intensity (below lactate threshold) running throughout the wh…
Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults
2017
AbstractIn normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial for both. We recorded event-related potentials to somatosensory and auditory stimuli in a passive change detection paradigm from 81 older and 38 young women and investigated their associations with cognitive performance. In older adults also associations to physical fitness were studied. The somatosensory mismatch response was attenuated in older adults and it associated with executive functions. So…
Metabolism via arginase or nitric oxide synthase: two competing arginine pathways in macrophages
2014
Macrophages play a major role in the immune system, both as antimicrobial effector cells and as immunoregulatory cells, which induce, suppress or modulate adaptive immune responses. These key aspects of macrophage biology are fundamentally driven by the phenotype of macrophage arginine metabolism that is prevalent in an evolving or ongoing immune response. M1 macrophages express the enzyme nitric oxide synthase (NOS), which metabolizes arginine to nitric oxide (NO) and citrulline. NO can be metabolized to further downstream reactive nitrogen species, while citrulline might be reused for efficient NO synthesis via the citrulline-NO cycle. M2 macrophages are characterized by expression of the…
cis-regulatory variation modulates susceptibility to enteric infection in the Drosophila genetic reference panel
2020
Abstract Background Resistance to enteric pathogens is a complex trait at the crossroads of multiple biological processes. We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understanding of how the effects of genetic variants affect different molecular mechanisms to determine gut immunocompetence is still limited. Results To address this, we perform a systems genetics analysis of the gut transcriptomes from 38 DGRP lines that were orally infected with Pseudomonas entomophila. We identify a large number of condition-specific, expression quantitative trait loci (local-eQTLs) with infection-specific ones located …
