Ecotourism : characteristics and involvement patterns of its consumers in the United Kingdom

Diamantis, Dimitrios January 1998 (has links)
Over the last ten years the increased demand for ecotourism has represented not only a growing trend in the tourism industry, but also one of the most significant challenges to the sector. It became evident over this type of consumer had shifted away from mass tourism towards experiences perceived to be more individualistic and enhancing. In part, this trend was stimulated by the increased global awareness of environmental issues which in turn, encouraged a growth in visits to natural areas and placed ecotourism at the centre of the re-orientation of tourism. This growth of demand for ecotourism initially ran ahead of the supply of ecotourism products, and created a new challenge for researchers and scholars in tourism. In particular, the consumer-driven demand for ecotourism created a disequilibrium in academic circles. For example,there are uncertainties and confusions both in terms of the definition of ecotourism and also in the enumeration of its fundamental principles; confusions which in part are derived from a lack of understanding of the behaviour of ecotourists. Indeed, it can be suggested that until the behaviour of ecotourists is fully explored it will continue to be difficult to clarify the concept of ecotourism. Having said this, there are a number ofstudies in the supply environments of North America and Australia which provide evidencet that ecotourists are consumers with strong motivations to be in and protect rather than profligate the natural environment. However, such studies have not been carried out in Europe and it is therefore the aim of this doctoral research to remedy this gap by examining the consumer behaviour of British ecotourists by using the involvement concept and techniques. In particular, this research concentrated on the assessment of the so-called occasional and frequent ecotourists, derived from their presence in the natural areas. These types of individuals provided the basis for the research analysis in which both qualitative and quantitative procedures were used to outline their characteristics and involvement patterns. The occasional ecotourists were subject to a quantitative assessment, where their involvement and ecotourism knowledge confirmed the existence of this type of ecotourist as well as their primary characteristics and values. With the intention to explore the product knowledge of frequent ecotourists the so-called laddering interviews were conducted which presented ecotourists knowledge structures,as well as providing a back bone for the quantitative assessment.In turn, this enabled both their profiles and involvement elementsto emerge aswell ashighlighted their value domains. Overall, this study underlined the behavioural andinvolvement patterns of thesetwo types ofecotouristsand indicatedthe elements of an ecotourism holiday experience which are not usually associated with this form of travel.

Soccer : physical characteristics, physical demands of match-play and effective physical conditioning

Bloomfield, Jonathan R. January 2005 (has links)
The overall purpose of this thesis was to examine the physical aspects of high performance soccer. As such, four interrelated studies were designed to pursue this purpose. Each study was designed to overcome certain distinct methodological limitations of previous science and football (soccer) research and build upon existing research. The research designs for each of the four studies were methodologically different and progressed from previous research design incorporating data collected and analysed from text and internet sources, computerised video-analysis of interactive televised material and combined performance and laboratory assessments. In the following section the purpose of each study included in this thesis is provided and the rationale underpinning the selection of each research design is explained. Study 1: Analysis of Age, Stature, Body Mass, BNH and Quality of Elite Soccer Players from four European Leagues For many sports, there are specific physical characteristics that indicate suitability for, or potential to compete in that sport at the highest level. Various anthropometric characteristics of athletes have been shown to be reasonable predictors for participation at the highest level in sports such as swimming (Ackland et al., 1993), basketball, rugby league and American football (Norton and Olds, 2000). Surprisingly, there is no research available exploring these characteristics in soccer, particularly within the elite European soccer. It might well be that the recent changes in demands in soccer( Williams et al., 1999) PhD Thesis 6 Jonathan R- Bloomfield have been accompanied by physical characteristic changes in soccer players that have been of greater magnitude than that of the normal population. This is an important issue because even small changes in these physical characteristics of players could result in a large reduction in the pool of people to draw from in the general population who have the suitable physical characteristics to be successful in soccer (Olds, 2001). Furthermore, the comparison of players in different leagues and in different positions might provide some valuable information regarding the different demands placed on soccer players in different leagues (Reilly et al, 2000a; Rienzi et al, 2000; Strudwick et al., 2002). It is well documented that different positions in soccer constitute various different demands. Such findings suggest heterogeneity in physical characteristics that might be important for success in particular positions in soccer (Strudwick et al., 2002). The first aim of the present study was to investigate whether there are physical differences (age, stature, body mass, body mass index) between players in different positions in four European soccer leagues. This will also provide information into the diversity in playing style as well as the variation in what is being valued in soccer players in the various countries. This results in valuable information for the adaptation of different physical conditioning regimes as well as implications for talent identification (Fisher and Dean, 1998). The second aim of the present study was to assess the quality of the players of each of the four European leagues by surveying their international status, nationality and FIFA world ranking as well as participation in the FIFA World Cup 2002. This will offer information regarding the actual quality of international players within these leagues which, in turn, provides information about which league would be of the highest quality, differences in playing style and player selection. As the four leading European leagues were selected for analysis, the results provide beneficial information concerning the current status and possible future development of European soccer. Study 2: The 'Bloomfield Movement Classification': Motion Analysis of Individual Soccer Players In close relation with the investigation of the physical characteristics of elite level players, it was also aimed to identify the physical demands of performance. Computerised video-analysis was selected as the most appropriate platform to incorporate a study using the time-motion analysis methodology. This involves the notation of various subjectively or objectively chosen modes of motion which are digitally timed throughout the performance. To date, fewer than 8 modes of motion have often been chosen in time-motion investigation in soccer which arguably does not provide a sufficient degree of specificity to detail the physical demands. A high element of performance specificity must be established to elicit a high degree of transfer from competition into a training regime to optimise competitive performance (Henry, 1968; Barnett et al., 1973; Sale and MacDougall, 1981; Rosenbaum, 1987; Morrissey et al., 1995; Hill et al., 1998). The present study outlined a new approach to time-motion analysis through a method involving a greater depth of detail concerning modes of timed-motion, as well as other non-timed movements, directions, intensities, turning and 'On the Ball' categories. The aim of this study was to present a new methodology and establish reliability. The purpose was to provide a new method to perform a more detailed time-motion analysis study in soccer performance to be used in the third study of this thesis. PhD Thesis 8 Jonathan R. Bloomfield Study 3: Physical Demands of Outfield Positions in FA Premier League Soccer. To elicit an enhancement in soccer performance, it is considered important to analyse the physical demands of match-play (Reilly and Thomas, 1976; All and Farrally, 1991a; Hughes, 2003). Time-motion analysis has been used to investigate these demands. However, many limitations exist with previous research, one of which being the range of classifications used in the collection of data- A high degree of performance specificity is desired to improve coaching practices such as physical conditioning (Barnett et al., 1973). To this end, a new time-motion analysis methodology was designed (see Study 2) and aimed at providing a new level of specificity of performance into the physical demands of high level soccer. Also, the majority of soccer-related time-motion analyses have reported macroscopically with total frequency, total duration or total distance covered providing a summary of the overall physical requirements of soccer. As soccer match-play is essentially an intermittent exercise (Bangsbo, 1994e), it is important to progress the knowledge of the physical nature of the sport and further provide a higher level of specific detail. The aims of the present study were to provide detail regarding intermittent patterns of Purposeful Movement (PM) and Recovery (R), performed by players of three different positions (defender, midfielder and striker), to investigate the reoccurrence of bouts of PM and R within selected time phases and finally provide time-motion analysis of the PM using the BMC. PhD Study 4: Effective Conditioning for Soccer Match-Play The interaction of multiple dynamic physical activities often produces a hybrid of physiological and biomechanical stresses. Higher levels of soccer require increased levels of physical fitness through increased demands from high intensity activity (O'Donoghue et al., 2001; Strudwick and Reffly, 2001; Mohr et al., 2003). Therefore, increased ability to perform complex chains of movement skills (agility) in conjuncture with speed (both acceleration and deceleration) and quickness (overcoming inertia) are relative to high level performance (Withers et al., 1982; Bangsbo, 1992; Reilly, 1994a). This occurs through processes of motor learning and physical conditioning with the rules of specificity and overload as key underlying principles.

Judo : a historical, statistical and scientific appraisal

Onda, Tetsuya January 1994 (has links)
This thesis presents the sport of Judo from historical, statistical and scientific perspectives. Modern Judo introduced in 1882 by Professor Jigoro Kano, used the combat element of Jujitsu, stressing the importance of mental and physical preparation. Judo rules evolved with changes in the scoring categories and style of Judo suit. Gradually Judo spread from Japan, and the International Judo Federation was created in 1951, initially consisting of only 12 countries, increasing to 157 in 1992. Statistical analysis of the 1991 World Championships and 1992 Olympic Games showed significant differences in scoring patterns between standing and groundwork techniques for male and female competitors. Groundwork techniques consistently resulted in Ippon. Uchi-Mata and Seoi-Nage were the most successful standing techniques, whilst Osae-Waza was the most successful groundwork technique for both genders. Based on these observations strength programmes to improve Uchi-Mata and Seoi-Nage were developed. A statistical comparison of the two championships indicated that all subgroups of competitors, except male non-medallists displayed the same scoring patterns. Judo can be considered as a multiple activity sport, where flurries of activity are interspersed with periods of recovery. Video analysis of the World Championship and Olympic Games showed that the average activity to recovery ratio was about 1-9: 1. Exercise intensity was studied by measuring cardiorespiratory and metabolic responses to Judo practice and competition. The intensity of exercise, based on blood lactate concentration, during competition was higher than the intensity of exercise during practice. To supplement Judo practice a specifically designed rowing exercise was prescribed. An interval programme was based on the average activity-to-rest ratio determined from the video analysis. Blood lactate concentration was higher, and heart rate lower, for rowing compared to Judo practice. Rowing with short intervals of high intensity separated by short recoveries appears to be a good whole body exercise for conditioning the power endurance component of Judo. Further research is required to confirm this preliminary observation.
