Determining Soil Hydraulic Properties Using Infiltrometer Techniques: An Assessment of Temporal Variability in a Long-Term Experiment under Minimum- …

2020

Conservation agriculture is increasingly accepted by farmers, but the modeling studies on agro-environmental processes that characterize these agricultural systems require accurate information on the temporal variability of the soil&rsquo

Variable mycorrhizal benefits on the reproductive output ofGeranium sylvaticum, with special emphasis on the intermediate phenotype

2012

In several gynodioecious species, intermediate sex between female and hermaphrodite has been reported, but few studies have investigated fitness parameters of this intermediate phenotype. Here, we examined the interactions between plant sex and arbuscular mycorrhizal (AM) fungal species affecting the reproductive output of Geranium sylvaticum, a sexually polymorphic plant species with frequent intermediate sexes between females and hermaphrodites, using a common garden experiment. Flowering phenology, AM colonisation levels and several plant vegetative and reproductive parameters, including seed and pollen production, were measured. Differences among sexes were detected in flowering, fruit …

Sedentary behaviours and obesity in adults: the Cardiovascular Risk in Young Finns Study

2013

Objective Sedentary behaviour may contribute to the development of obesity. We investigated the relations between different types of sedentary behaviour and adiposity markers in a well-characterised adult population after controlling for a wide range of potential confounders. Design Cross-sectional study. Setting The Cardiovascular Risk in Young Finns Multicenter Study. Participants Sedentary time (TV viewing, computer time, reading, music/radio listening and other relaxation) was assessed with a questionnaire for 1084 women and 909 men aged 30–45 years. Other study variables included occupational and leisure-time physical activity, sleep duration, socioeconomic status, smoking, alcohol con…

New technologies for promoting physical activity in healthy children and in children with chronic respiratory diseases: A narrative review

2021

Physical activity (PA) is proven to benefit children and adolescents in several ways. New technologies may provide children with stimulating modalities for organizing their leisure time, accessing fitness programs, and obtaining daily goal reminders and peer support. Due to the current COVID-19 pandemic, following WHO recommendations for PA is difficult for many children, especially for those living in urban areas. Therefore, the use of digital tools to support and maintain PA could be useful in healthy children, as well as in those with chronic respiratory diseases (CRDs). This narrative review aims to summarize the most recent evidence about the role of new technologies in promoting PA in…

Changes in Physical Activity, Motor Performance, and Psychosocial Determinants of Active Behavior in Children : A Pilot School-Based Obesity Program

2020

The obesity epidemic and the decline of fitness among children highlights the need for suitable interventions designed to promote Physical Activity (PA) and healthy habits. The purpose of our pilot study was to assess the feasibility of a school-based program among overweight and obese children, by examining changes in their body composition, PA, physical fitness, and some psychosocial determinants of active behavior. An additional objective was to investigate the reciprocal relationship over time between PA and body image. Self-reported PA and health-related fitness tests were administered to 18 overweight and obese children (11.3 ± 0.4 years), before and after a 6-month intervention inclu…

Effective strategies for promoting physical activity through the use of digital media among school-age children: A systematic review

2021

Digital media are widespread among school-age children, and their incorrect use may lead to an increase in sedentary levels and the consequences associated with it. There are still few studies that have investigated whether physical activity levels could be increased through their use. The aim of this study was to systematically review the scientific literature in order to identify whether digital strategies and technologies are capable of increasing the level of physical activity. A literature search was performed using the following databases: Pubmed, Scopus, and Web of Science. The main outcomes evaluated the increase in physical activity levels, the number of steps, and the reduction of…

Health Implications of Judo Training

2021

Although current physical activity (PA) guidelines regarding aerobic and anaerobic training are helpful for the population at large, many individuals prefer to engage in alternative forms of PA such as combat sports. As both a martial art and sport, judo is a physically demanding form of PA that potentially offers a novel experience, consequently leading to greater PA adherence. This study aimed to thoroughly search the existing literature to determine the health benefits of judo-specific training. PubMed and Web of Science were searched for original research studies. Only peer-reviewed studies that examined the effects of judo training in males and females aged 18–35 were included in the s…
