Effects of Off-Season Weight Training Programs on Development of Strength and Explosive Power of Football Players

Training to improve athletic performance is as old as the history of man. The ancient Persians began training their boys at the age of six, toughening them psychologically as well as physically by arduous activity under difficult and uncomfortable conditions. The ancient Greeks were fond of the training technique of running in sand with weights around the wrists and ankles. Some of these training techniques were remarkably scientific while others were based on tradition, ritual, or myth. From this colorful past have evolved our present day training programs which are based upon research results and tradition. With our present day football at such a high level of competitiveness, an off-season training program is certainly necessary. In this age of mechanization, many of the young men who desire to play and do play football lack the strength and endurance to compete safely and effectively. Statistics show an increase in the number of football injuries in the past few years, with almost fifty percent of those injuries occurring in the first three weeks of practice. The off-season football training program is of considerable value to the individual player who has the desire, determination and time to develop his potential to the fullest. Besides being an aid to the football player, such a program is of definite value to the coach who desires to prevent injuries and to develop a better team. Numerous studies have been completed to examine the effects of selected weight training programs upon various aspects of conditioning. However, it has been only recently that an attempt has been made to design an off season training program specifically for football. The present study was undertaken with the intent of providing football players and coaches with objective and practical knowledge about off-season football training programs

Service utilisation and family support of people with dementia: a cohort study in England.

Objectives This study aimed to compare costs of caring for people with dementia in domiciliary and residential settings, central England. Methods A cohort of people with dementia was recruited during a hospital stay 2008–2010. Data were collected by interview at baseline, and 6- and 12-month follow-up, covering living situation (own home with or without co-resident carer, care home); cognition, health status and functioning of person with dementia; carer stress; utilisation of health and social services; and informal (unpaid) caring input. Costs of formal services and informal caring (replacement cost method) were calculated. Costs of residential and domiciliary care packages were compared. Results Data for 109 people with dementia were collected at baseline; 95 (87.2%) entered hospital from their own homes. By 12 months, 40 (36.7%) had died and 85% of the survivors were living in care homes. Over one-half of people with dementia reported social care packages at baseline; those living alone had larger packages than those living with others. Median caring time for co-resident carers was 400 min/day and 10 h/week for non co-resident carers. Residential care was more costly than domiciliary social care for most people. When the value of informal caring was included, the total cost of domiciliary care was higher than residential care, but not significantly so. Carer stress reduced significantly after the person with dementia entered a care home. Conclusions Caring for people with dementia at home may be more expensive, and more stressful for carers, than care in residential settings

Theorising social class and its application to the study of health inequalities

The literature on health inequalities often uses measures of socio-economic position pragmatically to rank the population to describe inequalities in health rather than to understand social and economic relationships between groups. Theoretical considerations about the meaning of different measures, the social processes they describe, and how these might link to health are often limited. This paper builds upon Wright’s synthesis of social class theories to propose a new integrated model for understanding social class as applied to health. This model incorporates several social class mechanisms: social background and early years’ circumstances; Bourdieu’s habitus and distinction; social closure and opportunity hoarding; Marxist conflict over production (domination and exploitation); and Weberian conflict over distribution. The importance of discrimination and prejudice in determining the opportunities for groups is also explicitly recognised, as is the relationship with health behaviours. In linking the different social class processes we have created an integrated theory of how and why social class causes inequalities in health. Further work is required to test this approach, to promote greater understanding of researchers of the social processes underlying different measures, and to understand how better and more comprehensive data on the range of social class processes these might be collected in the future

Modification of plant cell walls with hydroxycinnamic acids by BAHD acyltransferases

In the last decade it has become clear that enzymes in the "BAHD" family of acyl-CoA transferases play important roles in the addition of phenolic acids to form ester-linked moieties on cell wall polymers. We focus here on the addition of two such phenolics-the hydroxycinnamates, ferulate and p-coumarate-to two cell wall polymers, glucuronoarabinoxylan and to lignin. The resulting ester-linked feruloyl and p-coumaroyl moities are key features of the cell walls of grasses and other commelinid monocots. The capacity of ferulate to participate in radical oxidative coupling means that its addition to glucuronoarabinoxylan or to lignin has profound implications for the properties of the cell wall - allowing respectively oxidative crosslinking to glucuronoarabinoxylan chains or introducing ester bonds into lignin polymers. A subclade of similar to 10 BAHD genes in grasses is now known to (1) contain genes strongly implicated in addition of p-coumarate or ferulate to glucuronoarabinoxylan (2) encode enzymes that add p-coumarate or ferulate to lignin precursors. Here, we review the evidence for functions of these genes and the biotechnological applications of manipulating them, discuss our understanding of mechanisms involved, and highlight outstanding questions for future research

Renewing Criminalized and Hegemonic Cultural Landscapes

The Mafia's long historical pedigree in Mezzogiorno, Southern Italy, has empowered the Mafioso as a notorious, uncontested, and hegemonic figure. The counter-cultural resistance against the mafiosi culture began to be institutionalized in the early 1990s. Today, Libera Terra is the largest civil society organization in the country that uses the lands confiscated from the Mafia as a space of cultural repertoire to realize its ideals. Deploying labor force through volunteer participation, producing biological fruits and vegetables, and providing information to the students on the fields are the principal cultural practices of this struggle. The confiscated lands make the Italian experience of anti-Mafia resistance a unique example by connecting the land with the ideals of cultural change. The sociocultural resistance of Libera Terra conveys a political message through these practices and utters that the Mafia is not invincible. This study draws the complex panorama of the Mafia and anti-Mafia movement that uses the ‘confiscated lands’ as cultural and public spaces for resistance and socio-cultural change. In doing so, this article sheds new light on the relationship between rural criminology and crime prevention policies in Southern Italy by demonstrating how community development practice of Libera Terra changes the meaning of landscape through iconographic symbolism and ethnographic performance

Theory driven analysis of social class and health outcomes using UK nationally representative longitudinal data

Background Social class is frequently used as a means of ranking the population to expose inequalities in health, but less often as a means of understanding the social processes of causation. We explored how effectively different social class mechanisms could be measured by longitudinal cohort data and whether those measures were able to explain health outcomes. Methods Using a theoretically informed approach, we sought to map variables within the National Child Development Study (NCDS) to five different social class mechanisms: social background and early life circumstances; habitus and distinction; exploitation and domination; location within market relations; and power relations. Associations between the SF-36 physical, emotional and general health outcomes at age 50 years and the social class measures within NCDS were then assessed through separate multiple linear regression models. R2 values were used to quantify the proportion of variance in outcomes explained by the independent variables. Results We were able to map the NCDS variables to the each of the social class mechanisms except ‘Power relations’. However, the success of the mapping varied across mechanisms. Furthermore, although relevant associations between exposures and outcomes were observed, the mapped NCDS variables explained little of the variation in health outcomes: for example, for physical functioning, the R2 values ranged from 0.04 to 0.10 across the four mechanisms we could map. Conclusions This study has demonstrated both the potential and the limitations of available cohort studies in measuring aspects of social class theory. The relatively small amount of variation explained in the outcome variables in this study suggests that these are imperfect measures of the different social class mechanisms. However, the study lays an important foundation for further research to understand the complex interactions, at various life stages, between different aspects of social class and subsequent health outcomes
