Effects of intra-session exercise sequence during water-based concurrent training.

2013

The aim was to investigate the effects of the intra-session exercise order during water-based concurrent training on the neuromuscular adaptations in young women. 26 women (25.1±2.9 years) were placed into 2 groups: resistance prior to (RA) or after (AR) aerobic training. Subjects performed resistance (sets at maximal effort) and aerobic training (exercises at heart rate corresponding to the second ventilatory threshold) twice a week over 12 weeks, performing both exercise types in the same training session. Upper (elbow flexion) and lower-body (knee extension) one-repetition maximum test (1RM) and peak torque (PT) were evaluated. The muscle thickness (MT) of upper (sum of MT of biceps brac…

Mechanical efficiency in athletes during running.

2007

The purpose of this study was to compare the external mechanical efficiency (ME) between power-trained athletes (n = 5) and endurance-trained athletes (n = 5). The relationships between biomechanical variables and metabolic cost were also investigated. The subjects ran at 3 different speeds (2.50 m.s-1, 3.25 m.s-1 and 4.00 m.s-1) both on the treadmill and on the track. The external work of the subjects was determined by a kinematic arm, and energy expenditure was determined by measuring oxygen consumption and respiratory exchange ratio. Biomechanical parameters included ground reaction forces, angular displacements of the knee and ankle joints and electromyography (EMG) of the selected musc…

Healthy Lifestyle and Complementary and Alternative Medicine.

2021

Having a healthy lifestyle is one of the main personal goals, and multiple behaviors can be used to achieve this goal. However, people do not always develop appropriate health behaviors. One of the consumption alternatives is the use of complementary and alternative medicine (CAM), which has been increasing significantly in recent years, although not always adequately. This study aimed to determine whether CAM use is associated with a healthy lifestyle in Spanish adults. To achieve these objectives, 2486 adults were interviewed as part of the 2018 Barometer of the Centro de Investigaciones Sociologicas about their lifestyle and CAM use. The findings show a relationship between healthy lifes…

Effect of biomass features on oxygen transfer in conventional activated sludge and membrane bioreactor systems

2019

Abstract The aim of the present study was to compare the oxygen transfer efficiency in a conventional activated sludge and a membrane bioreactor system. The oxygen transfer was evaluated by means of the oxygen transfer coefficient and α-factor calculation, under different total suspended solids concentration, extracellular polymeric substances, sludge apparent viscosity and size of the flocs. The oxygen transfer coefficient and α-factor showed an exponential decreasing trend with total suspended solid, with a stronger oxygen transfer coefficient dependence in the conventional activated sludge compared to the membrane bioreactor. It was noted that the oxygen transfer coefficient in the conve…

On the Macroeconomic Effect of Extortion: An Agent-Based Approach

2021

This work proposes an agent-based approach to study the effect of extortion on macroeconomic aggregates, despite the fact that there is little data on this criminal activity given its hidden nature. We develop a Bottom-up Adaptive Macroeconomics (BAM) model that simulates a healthy economy, including a moderate inflation and a reasonable unemployment rate, and test the impact of extortion on various macroeconomic signals. The BAM model defines the usual interactions among workers, firms and banks in labour, goods and credit markets. Subsequently, crime is introduced by defining the propensity of the poorest workers to become extortionists, as well as the efficiency of the police in terms of…

Seasonal changes in some thermoregulatory variables of the house sparrow (Passer domesticus L.)

1975

Abstract 1. The body weight, plumage, insulation, oxygen consumption and body lipids were studied seasonally in the house sparrow, Passer domesticus L. 2. The weights of body and plumage were greater in autumn and winter than in summer. 3. The insulative property of the plumage was better in autumn and winter birds than in summer birds. 4. The oxygen consumption of young birds was higher than that of plucked and adult birds. 5. The amount of subcutaneous depot fat tissue and its lipid content was greatest in autumn. The C18-unsaturated fatty acids were most prominent in the subcutaneous fat. Palmitic acid was the most prevalent fatty acid in the liver. The relative amount of C18-unsaturated…

Age affects the metabolic rate of insect brain.

1984

Abstract Brains of adult insects can be isolated and studied vitro. In female blowflies the oxygen uptake of the brain is age dependent. A steady increase is followed by a precipitous decrease around the middle of the life span. These changes are accompanied by alterations of mitochondrial structure and deposits of lipofuscin-like material.

Differential cysteine depletion in respiratory chain complexes enables the distinction of longevity from aerobicity.

2010

Mitochondrially encoded proteins in long-lived animals exhibit a characteristic anomaly on the amino acid usage level: they abstain from the use of cysteine in a lifespan-dependent fashion. Here, we have further investigated this phenomenon by analyzing respiratory chain complex subunits individually. We find that complex I cysteine depletion is the almost exclusive carrier of the cysteine-lifespan correlation, whereas complex IV cysteine depletion is uniform in all aerobic animals, unrelated to longevity, but even more pronounced than complex I cysteine depletion in the longest-lived species. In nuclear encoded subunits of the respiratory chain, we find lifespan-independent cysteine deplet…

Quality Markers and Consumer Communication Strategies: Empirical Evidence in the 'Very Fresh' Sector in Italy

2008

Quality is a key factor when consumers choose agri-food products, but at the same time is difficult for them to assess. On the demand side, consumers require protection measures, and on the supply side, efficient communications need to be available to all operators, including those who cannot afford to supply their own. In this context, quality markers such as logos, brands and indications or denominations that distinguish a product from its competitors can be a strategic way of transmitting information, especially for firms which cannot afford resources for communications or their own brand name. This research analyses and assesses the role of brands and territorial markers (PDO, PGI) in e…
