Recreational use of a marine protected area: Point Lonsdale, Victoria

This This article reports findings from observational and questionnaire surveys of visitors to a Marine Protected Area (MPA) at Point Lonsdale, Victoria. The MPA was established primarily to protect the biodiversity of intertidal rock platforms, with only limited restrictions being placed on fishing. Visitor surveys were undertaken to identify and quantify recreational uses, assess level of compliance with regulations, identify the uses most likely to have damaging impacts on biota, and to assess awareness of, and support for, this MPA and for MPAs in general. A questionnaire survey of visitors supported observational survey findings concerning recreational use patterns and provided information on awareness about and attitudes towards conservation measures for this location and for Victoria's marine environment. The finding that about half the visitors were not aware that
they were visiting a marine protected area has implications for future management of this area and MPAs in general. Most visitors indicated support for the concept of marine conservation areas and marine protected areas.

The effects of short-term sprint training on MCT expression in moderately endurance-trained runners

The purpose of this study was to assess the effects of short-term sprint training on transient changes in monocarboxylate lactate transporter 1 (MCT1) and MCT4 protein and mRNA content. Seven moderately endurance-trained runners (mean ± SE; age 27.7±2.9 years, body mass 81.1±5.9 kg, VO₂ max 58.1±2.0 ml kg⁻¹ min⁻¹) completed a VO₂ max and a supramaximal running test to exhaustion (RTE) before and after a 6-week period of sprint training. The sprint training was progressive and consisted of 18 sessions of near maximal short duration (5–15 s) sprints to compliment the athlete’s endurance training. Prior to the training period there was a significant (P<0.05) increase in MCT1, but not MCT4 protein, 2 h after the RTE. This occurred without any change in corresponding mRNA levels. After the training period, there was a significant increase in MCT1 protein but no significant change in the MCT4 isoform. Both MCT1 and MCT4 mRNA was significantly lower at rest and 2 h post-RTE after the completion of the training period. After the training period, there was a significant increase in the time to exhaustion and distance covered during the RTE. This study demonstrates that sprint training of this length and type results in an upregulation of MCT1 protein, but not MCT4 content. Additionally, this study shows conflicting adaptations in MCT1 and MCT4 protein and mRNA levels following training, which may indicate post-transcriptional regulation of MCT expression in human muscle.

Work and recreational changes among people with neurological illness and their caregivers

Background. Progressive neurological illnesses alter the health and well-being of people who experience them, and frequently lead to changes in the activities of both patients and their carers.

Purpose. The current study investigated changes in work and recreational activities among people with four of these illnesses.

Method. In total, the following numbers of people with neurological illnesses and their carers participated in the study: 28 with multiple sclerosis; 27 with motor neurone disease; 31 with Parkinson's; and 24 with Huntingtons disease. In addition, 28 professionals who worked with these populations participated in the study. Individual interviews were conducted with each of the above respondents to determine the impact of the neurological illness.

Results. The results demonstrated a high level of agreement from each of the participants. Most of the people with the illnesses and many of the carers had reduced their level of paid work. Generally, all groups of respondents perceived these changes as being negative. Changes in recreational activities were also seen to be primarily negative.

Conclusions. These results are discussed in terms of proposed prevention and intervention programmes to prepare patients and their carers for the changes that result from the neurological illness, strategies to stay at work longer and to help them develop alternative strategies to assist them in filling the gap left in their lives that was previously occupied by paid work.

Rural sports and recreational injuries in Australia: what do we know?

Objective: It is widely recognised that individuals residing in regional or rural areas have poorer health outcomes than those from metropolitan areas. Factors associated with these poorer health outcomes include geographical isolation, population declines, limited health care provision and higher levels of inactivity compared to urban areas. The mental, social and physical health of individuals and communities in rural areas can be improved through active participation in sport and recreation activities. Unfortunately, participation in such activities can potentially lead to injury. There is a suggestion that there is an increased risk of sports injuries in rural areas due to the lack of health professionals and coaching personnel, fewer available volunteers to organise and deliver sport, and the general attitude towards injuries in rural settings.

Results: There is very limited information about the number and types of injuries sustained during participation in sports activities in rural and regional settings. This is largely related to a lack of formal sporting structures and support mechanisms including research funding and trained personnel.

Conclusion: A range of factors need to be implemented to improve safety for sporting and recreational participants in these areas. These include improved monitoring of injury occurrence, stronger promotion of safety initiatives and wider implementation of education strategies.

Harm reduction and decision making among recreational ecstasy users

Recent research indicates that 3,4-methylene-dioxymethamphetamine (MDMA), also known as ‘ecstasy’, is becoming increasingly popular as an illicit drug among young people. This study investigated risk and harm reduction practices among recreational ecstasy users. A semi-structured interview with 40 participants was designed to investigate how ecstasy users identify and manage the harms associated with their drug use, and the underlying decision-making process. Overall, the participants identified both positive and negative effects. The reported positive effects predominantly centred around enhanced psychological, physiological and social experiences. However, there were a number of factors that contributed to regulating ecstasy use. These included specific in-group and out-group practices executed within the peer group, preventative harm-reducing practices, shared decision making, and shared responsibility for harm prevention. Recommendations for promoting harm reduction strategies and suggestions for future research are discussed.

Recreational facilities and leisure-time physical activity : an analysis of moderators and self-efficacy as a mediator

Objective: To examine socio-demographic and psychosocial moderators, and self-efficacy as a mediator of the cross-sectional relationships between having access to recreational facilities and leisure-time physical activity (LTPA); to investigate the extent to which the environment-LTPA associations could be explained by self-selection to neighborhoods.

Design: A two-stage stratified sampling design was used to recruit 2,650 adults (aged 20-65) from 32 urban communities varying in walkability and socioeconomic status. Participants reported perceived access to facilities and home equipment for LTPA, weekly minutes of LTPA, self-efficacy for and enjoyment of LTPA, reasons for neighborhood selection, and socio-demographic characteristics.

Main Outcome Measures: Self-reported recreational walking and other forms of moderate-to-vigorous LTPA expressed in MET-minutes.

Results: Specific types of recreational facilities were independently  associated with LTPA. Age, education, being overweight/ obese, reasons for neighborhood selection, enjoyment of, and self-efficacy for LTPA moderated these relationships. Self-efficacy was not a significant mediator of these cross-sectional associations.

Conclusion: These findings have potentially significant implications for the planning of environmental interventions aimed at increasing population-level LTPA particularly in those who are less attitudinally inclined to being physically active.

Building brand identity : Does it pay? An investigation into cultural and recreational services

This conceptual paper aims to contribute to current services branding literature by conceptualising the relationship between brand identity and critical antecedents and empirically verifying whether the creation of a strong brand identity results in the ultimate pay off in terms of improved organisational performance. A conceptual model is developed in the context of the cultural and recreational services sector and central constructs and subsequent propositions are discussed.

Area variation in recreational cycling in Melbourne : a compositional or contextual effect?

Objective: To examine whether compositional and/or contextual area characteristics are associated with area socioeconomic inequalities and between-area differences in recreational cycling.

Setting: The city of Melbourne, Australia.

Participants: 2349 men and women residing in 50 areas (58.7% response rate).

Main outcome measure: Cycling for recreational purposes (at least once a month vs never).

Design: In a cross-sectional survey participants reported their frequency of recreational cycling. Objective area characteristics were collected for their residential area by environmental audits or calculated with Geographic Information Systems software. Multilevel logistic regression models were performed to examine associations between recreational cycling, area socioeconomic level, compositional characteristics (age, sex, education, occupation) and area characteristics (design, safety, destinations or aesthetics).

Results: After adjustment for compositional characteristics, residents of deprived areas were less likely to cycle for recreation (OR 0.66; 95% CI 0.43 to 1.00), and significant between-area differences in recreational cycling were found (median odds ratio 1.48 (95% credibility interval 1.24 to 1.78). Aesthetic characteristics tended to be worse in deprived areas and were the only group of area characteristics that explained some of the area deprivation differences. Safety characteristics explained the largest proportion of between-area variation in recreational cycling.

Conclusion: Creating supportive environments with respect to safety and aesthetic area characteristics may decrease between-area differences and area deprivation inequalities in recreational cycling, respectively.

Slow component of VO2 during level and uphill treadmill running : relationship to aerobic fitness in endurance runners

The aim of this study was to compare the oxygen uptake (VO^sub 2^) slow component (SC) during level and uphill running in endurance runners, and to identify associations between the SC and the following aerobic fitness indicators: peak VO^sub 2^, running speed associated with the peak VO^sub 2^ (Vpeak), running speed at the lactic threshold and the VO^sub 2^ fraction elicited at the lactic threshold. Fourteen male endurance-trained runners underwent several 6-min bouts of level (LTR) and 10.5% uphill treadmill running. VO^sub 2^ SC was calculated as the difference between mean VO^sub 2^ during the 6th and the 3rd minutes. The highest mean values for the SC were 181.9±240.2 mL*min^sup -1^ for level running at ~94% peak VO^sub 2^ and 105.4±154.6 mL*min^sup -1^ for uphill running at ~90% peak VO^sub 2^. The SC observed during the last bout of the LTR correlated with peak VO^sub 2^ and with Vpeak (-0.71 and -0.76, P<0.05, respectively). The results show that for endurance-trained runners the magnitude of the SC is not affected by the treadmill gradient and that within a homogeneous sample of endurance-trained runners the SC does not correlate with indicators of aerobic fitness.

Vigorous exercise and birth outcomes in a sample of recreational exercisers : a prospective study across pregnancy

Objective: This study examined the question of whether vigorous exercise undertaken by recreational exercisers across pregnancy, defined in two ways, were associated with reduced infant birthweight and gestational age at birth.

Methods: A prospective approach was implemented. A total of 148 pregnant women participated. Average intensity duration and frequency of vigorous exercise reported were examined and compared with two existing definitions of vigorous exercise. Participants completed questionnaires (including retrospective reports on 3 months prepregnancy) and an exercise diary at 16–23 weeks pregnancy, 24–31 weeks pregnancy and 32–38 weeks pregnancy, and at 7 to 14 days post-partum a birth outcomes questionnaire was completed.

Results: There were no significant differences between exercise groups for birthweight and gestational age at birth.

Conclusions: There was no evidence that the intensity duration and frequency of vigorous exercise were associated with significant reductions in mean birth outcomes for the infants of women who participated in the study. Replication in a large, more diverse sample is recommended.

Risk and harm reduction among recreational ecstasy users

Ecstasy users' perceptions of risk, harm reduction and decision making practices were examined in 153 adults. Identified were a range of positive and negative effects attributed to using ecstasy. There was only a weak association between risk perception, other risk taking behaviours and high ecstasy use. However, the role of the peer group was found to be an important factor in the reducation of harm, and in particular, the decision making process.

Anaerobic capacity and adaption of endurance-trained runners

Demonstrates that anaerobic capacity, using the accumulated oxygen deficit technique, can be measured rapidly and with a high degree of precision, however significant difficulties remain to be addressed. Significant further insights into some of the underlying cellular mechanisms associated with increases in anaerobic capacity were also obtained.
