Improved Physical Health in Middle-Older Aged Golf Caddies Following 24 Weeks of High-Volume Physical Activity.

BACKGROUND: The physical demands of golf caddying, including walking while carrying a golf bag, may potentially affect body composition, and markers of metabolic, cardiovascular, and musculoskeletal health. Therefore, this study examined the impact of 24 weeks of caddying on physical health in middle-older aged males. METHODS: Eleven full-time experienced male caddies (age: 59 [8] y; caddying experience: 14 [12] y) were recruited from a local golf course. The following were assessed at preseason and after 24 weeks of caddying (March-September 2022): body composition, heart rate, blood pressure, blood lipids, and performance tests (static and dynamic balance, strength, and submaximal fitness). Physical activity (PA) levels were assessed at preseason and at the mid-point of the caddying season. Across the caddying season, participants completed a monthly average of 24.0 (3.8) rounds. RESULTS: Following the caddying season, improvements in static balance (Δ = 13.5 s), dynamic balance (Δ = -1.8 s), and lower back absolute strength (Δ = 112.8 N), and muscle quality (Δ = 2.0 N·kg-1) were observed (all P < .05). Additionally, blood lipids, including total cholesterol (Δ = -0.6 mmol·L-1), high-density lipoprotein cholesterol (Δ = 0.1 mmol·L-1), low-density lipoprotein cholesterol (Δ = -0.6 mmol·L-1) (all P < .05), and body composition, including body mass (Δ = -2.7 kg), fat mass (Δ = -1.9 kg), fat percentage (Δ = -1.4%), fat-to-muscle ratio (Δ = -0.03), and body mass index (Δ = -0.9 kg·m-2) (all P < .05) improved. Caddying did not offer beneficial changes to cardiovascular variables or cardiorespiratory fitness (P > .05), while coronary heart disease risk score decreased (Δ = -3.3%) (P < .05). In relation to PA, light- (Δ = 145 min) and moderate-intensity (Δ = 71 min) PA, moderate to vigorous PA (Δ = 73 min), and total PA (Δ = 218 min) between preseason and the mid-point of the caddying season increased, while sedentary time (Δ = -172 min) decreased (all P < .05). CONCLUSION: Golf caddying can provide several physical health benefits such as improvements in various markers of cardiometabolic health, lower back absolute strength, and static and dynamic balance. The physical health improvements that caddying offers is likely contributed to by increased PA volume and intensity through walking on the golf course. Therefore, caddying may represent a feasible model for increasing PA volume and intensity and achieve physical health-related benefits.

Professional development themes in strength and conditioning coaches.

The purpose of this study was to explore professional development themes in experienced strength and conditioning coaches. Strength and conditioning coaches (N = 15, mean age = 34.3 years, SD = 5.2 years) with 11.4 (SD = 4.9) years experience working with elite, professional, or talented athletes were interviewed about their professional development. The interviews were transcribed verbatim and content analyzed. Over time, subjects' service-delivery practices became more flexible and client driven. Their role understanding also broadened to include various dimensions, such as the need to consider various stakeholders and the value of good relationships with athletes. The subjects shifted from relying on external justification for professional decision making to their experience-based knowledge. The subjects believed athlete work experience, interactions with senior strength and conditioning coaches and other colleagues, the professional literature, and nonprofessional experiences, such as their own athletic experience and sales or managerial training, were the primary influences on their professional development. Typically, the subjects experienced anxiety about their competence, both early in their careers and when working in new contexts or with new athlete groups, but over time, they developed increased confidence. In addition, the subjects experienced reduced narcissism over time about the control they had over athletes and their competitive results. The current results provide information about the characteristics of effective strength and conditioning coaches, the ways they develop their competencies to help athletes, and the emotions they experience throughout their careers. These results may help strength and conditioning practitioners in planning and optimizing their professional development and effectiveness with athletes.

Golf and Physical Health: A Systematic Review.

BACKGROUND: No previous systematic review has examined the physical health benefits of playing golf or caddying. OBJECTIVE: To establish the influence of golf participation and physical health in golfers and caddies. More specifically, the review intended to explore the domains of cardiovascular, metabolic and musculoskeletal health, in addition to body composition. DESIGN: Systematic review. DATA SOURCES: Electronic literature searches were conducted using PubMed, SPORTDiscus and CINAHL databases in July 2021. ELIGIBILITY CRITERIA: Experimental (randomised controlled trials, quasi-experiment, pre-post) and non-experimental (case-control, cross-sectional, cohort) articles relating to health and golf, written in English and published in peer-reviewed journals. RESULTS: Of the 572 articles initially identified, 109 full-text articles were assessed for eligibility with 23 meeting the inclusion criteria. Sixteen articles were rated 'good 'and seven 'fair'. The influence of golf on physical health was mixed, although various articles displayed improvements in balance, systolic blood pressure (SBP) and diastolic blood pressure (DBP), high density lipoprotein-cholesterol (HDL-C) and the ratio of HDL to total cholesterol within golfers. Caddies observed improvements in bone mineral density (BMD), stiffness index and strength. Most of the findings indicate that playing golf or caddying does not influence body mass index (BMI); however, playing golf can positively change other body composition markers such as lean and fat mass. CONCLUSION: This review demonstrated that golf participation may be an effective method for improving musculoskeletal and cardiovascular health, although mixed findings were observed. Moreover, limited longitudinal evidence suggests that playing golf can positively impact metabolic health and the influence on body composition may be parameter dependent. Additionally, the initial evidence suggests that caddying may improve musculoskeletal health. However, the studies included were limited by their methodological inconsistencies such as: study design, participant demographics and intervention prescription.

Variability in muscle dysmorphia symptoms: the influence of weight training.

The purpose of this study was to examine the influence of a weight training session on muscle dysmorphia symptoms in young men who regularly weight trained. Using a within-subjects crossover design, 30 men (mean ± SD; 20.93 ± 2.60 years, 86.87 ± 10.59 kg, and 1.76 ± 0.01 m) were randomly allocated to 1 of 2 groups, and completed the Muscle Dysmorphic Disorder Inventory twice, once each on 2 separate days. One day 1, group 1 completed the questionnaire after a weight training session and group 2 on a rest day. One day 2, group 1 completed the questionnaire on a rest day and group 2 after a weight training session. The mean score for drive for size was significantly higher on a rest day (18.00) than on a training day (15.87; p = 0.001, d = 1.03). The mean score for appearance intolerance was significantly higher on a rest day (10.10) compared with that on a training day (8.97; p = 0.001, d = 0.69). The mean score for functional impairment was significantly higher on a rest day (10.20) than on a training day (9.47; p = 0.037, d = 0.40). These results provide evidence that muscle dysmorphia symptoms have state-like properties and may be influenced by situational variables. The results may indicate that strength and conditioning specialists and mental health professionals need to observe clients over time and take into account environmental variables before making decisions about the presence or absence of the condition.

The Impact of the Closure and Reopening of Golf Courses in the United Kingdom on Wellbeing During the COVID-19 Pandemic: A Multi-Study Approach.

The purpose of this multi-study was to assess what impact the closure and reopening of golf courses had on: personal competence; sense of belonging; enjoyment; self-esteem; self-confidence; resilience; social connections; wellbeing and life satisfaction (hereafter referred to collectively as "key variables of interest") during the COVID-19 pandemic. Golfers (Study 1: n = 298, Study 2: n = 124) ≥16 years old residing in the UK participated in this study which collected data using online surveys. Study 1 was conducted during a period of quarantine restrictions (4-12th May 2020), whilst study 2 took place following the easing of the COVID-19 quarantine restrictions (6-14th July 2020). Within study 1 and study 2, key variables of interest levels were also collected to investigate the association with golf related activities. The findings of study 1 highlighted that negligible and non-significant correlations were observed between golf physical and sedentary activities and key variables of interest (r < 0.3, p > 0.05) except sense of belonging and sedentary golf activities (r = 0.178, p = 0.003). Study 2 highlighted that sense of belonging, enjoyment and wellbeing were significantly associated with outdoor golf course activity (r = 0.186-0.252, p ≤ 0.05). Furthermore, when comparing study 1 and study 2, sense of belonging and life satisfaction significantly improved (p < 0.05, d = 0.2). Based on these findings, playing golf on outdoor golf courses appears to be positively related to sense of belonging, enjoyment and wellbeing. Also, with the reopening of golf courses life satisfaction improved which, together, highlights the beneficial impact that outdoor golf can impart.

Contrasting Pathways for Anaerobic Methane Oxidation in Gulf of Mexico Cold Seep Sediments.

Gulf of Mexico sediments harbor numerous hydrocarbon seeps associated with high sedimentation rates and thermal maturation of organic matter. These ecosystems host abundant and diverse microbial communities that directly or indirectly metabolize components of the emitted fluid. To investigate microbial function and activities in these ecosystems, metabolic potential (metagenomic) and gene expression (metatranscriptomic) analyses of two cold seep areas of the Gulf of Mexico were carried out. Seeps emitting biogenic methane harbored microbial communities dominated by archaeal anaerobic methane oxidizers of phylogenetic group 1 (ANME-1), whereas seeps producing fluids containing a complex mixture of thermogenic hydrocarbons were dominated by ANME-2 lineages. Metatranscriptome measurements in both communities indicated high levels of expression of genes for methane metabolism despite their distinct microbial communities and hydrocarbon composition. In contrast, the transcription level of sulfur cycle genes was quite different. In the thermogenic seep community, high levels of transcripts indicative of syntrophic anaerobic oxidation of methane (AOM) coupled to sulfate reduction were detected. This syntrophic partnership between the dominant ANME-2 and sulfate reducers potentially involves direct electron transfer through multiheme cytochromes. In the biogenic methane seep, genes from an ANME-1 lineage that are potentially involved in polysulfide reduction were highly expressed, suggesting a novel bacterium-independent anaerobic methane oxidation pathway coupled to polysulfide reduction. The observed divergence in AOM activities provides a new model for bacterium-independent AOM and emphasizes the variation that exists in AOM pathways between different ANME lineages. IMPORTANCE Cold seep sediments are complex and widespread marine ecosystems emitting large amounts of methane, a potent greenhouse gas, and other hydrocarbons. Within these sediments, microbial communities play crucial roles in production and degradation of hydrocarbons, modulating oil and gas emissions to seawater. Despite this ecological importance, our understanding of microbial functions and methane oxidation pathways in cold seep ecosystems is poor. Based on gene expression profiling of environmental seep sediment samples, the present work showed that (i) the composition of the emitted fluids shapes the microbial community in general and the anaerobic methanotroph community specifically and (ii) AOM by ANME-2 in this seep may be coupled to sulfate reduction by Deltaproteobacteria by electron transfer through multiheme cytochromes, whereas AOM by ANME-1 lineages in this seep may involve a different, bacterium-independent pathway, coupling methane oxidation to elemental sulfur/polysulfide reduction.

The adjunctive role of imagery on the functional rehabilitation of a grade II ankle sprain.

The purpose of the present study was to examine the effectiveness of imagery on muscular endurance, dynamic balance, and functional stability in athletes who sustained a grade II ankle sprain. The sample consisted of 20 active athletes (aged from 18 to 30 years) with a grade II ankle sprain, as confirmed by ultrasound testing. The participants were randomly divided into two groups of 10 participants each; one experimental and one control group. The experimental group received 12 individual sessions of imagery rehearsal in addition to a normal course of physical therapy, while the control group followed only the physical therapy treatment. Results revealed significant differences only in the variable of muscular endurance. This study partly supports the contribution of imagery to the functional rehabilitation of grade II ankle sprain. Further research should be conducted to examine the effect of imagery on the functional rehabilitation of sport injuries using other tests of functional rehabilitation along with larger sample sizes.

Psychological responses to injury in competitive sport: a critical review.

Research has attempted to examine the psychological impact of athletic injury to assist rehabilitation personnel when treating injured athletes. Sports trainers, sports therapists, physiotherapists, medical staff and sports psychologists should be aware of psychological factors impacting on the injury experience when involved in an athlete's rehabilitation. A number of models have been proposed as useful frameworks for investigating and describing the psychological response to athletic injury. Many researchers have relied upon applying or adapting grief and cognitive appraisal models originally derived from the clinical and stress related psychology literature in an attempt to describe the psychological response to athletic injury. This article provides an overview of these models and offers a critical appraisal of this research, specifically focusing on the grief response models and the integrated model of response to sport injury and rehabilitation. Criticisms focus on the lack of research supporting a uniformed sequence of stages as a feature of response to athletic injury. Further grief criticisms centre on the absence of denial in much of the research to date. The article then focuses on the dynamic core of the integrated response to sport injury and rehabilitation model. It is argued that the interrelationships between emotional responses, behavioural responses, cognitive appraisals and recovery outcomes are not as simple as suggested in the model.

Comparative metagenomics of hydrocarbon and methane seeps of the Gulf of Mexico.

Oil and gas percolate profusely through the sediments of the Gulf of Mexico, leading to numerous seeps at the seafloor, where complex microbial, and sometimes animal communities flourish. Sediments from three areas (two cold seeps with contrasting hydrocarbon composition and a site outside any area of active seepage) of the Gulf of Mexico were investigated and compared. Consistent with the existence of a seep microbiome, a distinct microbial community was observed in seep areas compared to sediment from outside areas of active seepage. The microbial community from sediments without any influence from hydrocarbon seepage was characterized by Planctomycetes and the metabolic potential was consistent with detrital marine snow degradation. By contrast, in seep samples with methane as the principal hydrocarbon, methane oxidation by abundant members of ANME-1 was likely the predominant process. Seep samples characterized by fluids containing both methane and complex hydrocarbons, were characterized by abundant Chloroflexi (Anaerolinaceae) and deltaproteobacterial lineages and exhibited potential for complex hydrocarbon degradation. These different metabolic capacities suggested that microorganisms in cold seeps can potentially rely on other processes beyond methane oxidation and that the hydrocarbon composition of the seep fluids may be a critical factor structuring the seafloor microbial community composition and function.

Family experiences of living with an eating disorder: a narrative analysis.

Families are considered important in the management and treatment of eating disorders. Yet, rarely has research focused on family experiences of living with an eating disorder. Addressing this gap, this study explores the experiences of an elite 21-year-old triathlete with an eating disorder in conjunction with the experiences of her parents. Family members attended interviews individually on three separate occasions over the course of a year. In line with the narrative approach adopted, whereby stories are considered the primary means to construct experience, interviews encouraged storytelling through an open-ended, participant-led structure. Narrative analysis involved repeated readings of the transcripts, sensitising towards issues of narrative content (key themes) and structure (overarching plot). Family difficulties arose when personal experiences strayed from culturally dominant narrative forms and when family members held contrasting narrative preferences. Suggestions are forwarded as to how an appreciation of eating disorder illness narratives might inform treatment and support.

UK adults' implicit and explicit attitudes towards obesity: a cross-sectional study.

BACKGROUND: Anti-fat attitudes may lead to stigmatisation of and lowered self-esteem in obese people. Examining anti-fat attitudes is warranted given that there is an association with anti-fat behaviours. Previous studies, mainly outside the UK, have demonstrated that anti-fat attitudes are increasing over time. METHODS: The study was cross-sectional with a sample of 2380 participants (74.2 % female; aged 18-65 years). In an online survey participants reported demographic characteristics and completed a range of implicit and explicit measures of obesity related attitudes. RESULTS: Perceptions of obesity were more negative than reported in previously. Main effects indicated more negative perceptions in males, younger respondents and more frequent exercisers. Attitudes about obesity differed in relation to weight category, and in general were more positive in obese than non-obese respondents. CONCLUSIONS: This is the first study to demonstrate anti-fat attitudes across different sections of the UK population. As such, this study provides the first indication of the prevalence of anti-fat attitudes in UK adults. Interventions to modify these attitudes could target specific groups of individuals with more negative perceptions as identified here. Future work would be useful that increases understanding of both implicit and explicit attitudes towards obesity.

A Social Identity Approach to Sport Psychology: Principles, Practice, and Prospects.

Drawing on social identity theory and self-categorization theory, we outline an approach to sport psychology that understands groups not simply as features of sporting contexts but rather as elements that can be, and often are, incorporated into a person's sense of self and, through this, become powerful determinants of their sport-related behavior. The underpinnings of this social identity approach are outlined, and four key lessons for sport that are indicative of the analytical and practical power of the approach are presented. These suggest that social identity is the basis for sports group (1) behavior, (2) formation and development, (3) support and stress appraisal, and (4) leadership. Building on recent developments within sport science, we outline an agenda for future research by identifying a range of topics to which the social identity approach could fruitfully contribute.

Efficacy of physical activity interventions in post-natal populations: systematic review, meta-analysis and content coding of behaviour change techniques.

This systematic review and meta-analysis reports the efficacy of post-natal physical activity change interventions with content coding of behaviour change techniques (BCTs). Electronic databases (MEDLINE, CINAHL and PsychINFO) were searched for interventions published from January 1980 to July 2013. Inclusion criteria were: (i) interventions including ≥1 BCT designed to change physical activity behaviour, (ii) studies reporting ≥1 physical activity outcome, (iii) interventions commencing later than four weeks after childbirth and (iv) studies including participants who had given birth within the last year. Controlled trials were included in the meta-analysis. Interventions were coded using the 40-item Coventry, Aberdeen & London - Refined (CALO-RE) taxonomy of BCTs and study quality assessment was conducted using Cochrane criteria. Twenty studies were included in the review (meta-analysis: n = 14). Seven were interventions conducted with healthy inactive post-natal women. Nine were post-natal weight management studies. Two studies included women with post-natal depression. Two studies focused on improving general well-being. Studies in healthy populations but not for weight management successfully changed physical activity. Interventions increased frequency but not volume of physical activity or walking behaviour. Efficacious interventions always included the BCTs 'goal setting (behaviour)' and 'prompt self-monitoring of behaviour'.

A cognitive-behavioural analysis of mental toughness in national rugby league football teams.

This study examined the relations between demographic characteristics of rugby players and selected aspects of psychological performance in rugby league football. Mental toughness was assessed using Psychological Performance Inventory and Hardiness on the Personal Views Survey III-R. Participants (N=70) were international rugby league footballers representing four teams (Wales, France, Ireland, England) in the 2000 Rugby League World Cup. Participants completed the questionnaires in training camp. Welsh-nationality players had a significantly higher mean score on two of the hardiness subscales. Hardiness measures displayed the greatest and most frequently statistically significant differences. The findings concur with previous work indicating superior hardiness is related to improved performance in sports.

A Social Support Intervention to Reduce Intentions to Drop-out from Youth Sport: The GAA Super Games Centre / Una intervención basada en el apoyo social para reducir la intención de abandonar el deporte juvenil: el Centro de Superjuegos GAA

Research has highlighted that drop-out from youth sport has emerged to become a global trend with drop-out rates exceeding 30% in some countries. This study aimed to investigate the effect of a change in perceived support on intentions to drop out from youth sport at the end of a social support intervention. A pre-intervention examination of the Gaelic Athletic Association (GAA) in 2012 identified a 19.38% drop-out rate involving 3,491 participants between the ages of 12-16 years. A psychosocial intervention developed for the GAA called the Super Games Centre was delivered and evaluated over a 24-week period to 103 participants. The findings demonstrated that higher perceived available support was significantly associated with lower levels of intentions to drop out at the end of the intervention. Furthermore, social identity emerged as a significant mediating factor in explaining the association between changes in perceived support and intentions to drop out. A post-intervention examination in 2018 found that the GAA had established 95 Super Games Centres since 2015, and this has led to an increase in 7,012 new participants between the ages of 12-16 years. Future research and implications for social support intervention methodology are discussed

La investigación ha destacado que el abandono del deporte juvenil se ha convertido en una tendencia mundial con tasas que superan el 30% en algunos países. Este estudio tiene como objetivo investigar el efecto de un cambio en el apoyo percibido sobre la intención de abandonar el deporte juvenil al finalizar una intervención basada en el apoyo social. La Asociación Atlética Gaélica (GAA) en 2012 identificó una tasa de abandono del 19.38% que involucraba a 3,491 participantes de edades comprendidas entre 12-16 años. Una intervención psicosocial desarrollada para la GAA, llamada Centro de Superjuegos (Super Games Centre), se realizó con 103 participantes y se evaluó durante un período de 24 semanas. Los resultados muestran que la percepción de una mayor disponibilidad de apoyo social se asocia significativamente a niveles más bajos de intención de abandono al final de la intervención. Además, la identidad social demostró ser un importante factor de mediación para explicar la asociación entre los cambios en el apoyo percibido y la intención de abandono. Un examen posterior a la intervención en 2018 encontró que la GAA había creado 95 Centros de Superjuegos desde 2015, lo que ha llevado a un aumento de 7,012 nuevos participantes en el mismo rango de edad (12-16 años). Se debaten las investigaciones futuras y las implicaciones para la metodología de intervención basada en el apoyo social

Counter-Conditioning as an Intervention to Modify Anti-Fat Attitudes.

This study examined the effect of anti-fat attitude counter-conditioning using positive images of obese individuals participants completed implicit and explicit measures of attitudes towards fatness on three occasions: no intervention; following exposure to positive images of obese members of the general public; and to images of obese celebrities. Contrary to expectations, positive images of obese individuals did not result in more positive attitudes towards fatness as expected and, in some cases, indices of these attitudes worsened. Results suggest that attitudes towards obesity and fatness may be somewhat robust and resistant to change, possibly suggesting a central and not peripheral processing route for their formation.

Efficient, physiologically realistic lung airflow simulations.

One of the key challenges for computational fluid dynamics (CFD) simulations of human lung airflow is the sheer size and complexity of the complete, multiscale geometry of the bronchopulmonary tree. Since 3-D CFD simulations of the full airway tree are currently intractable, researchers have proposed reduced geometry models in which multiple airway paths are truncated downstream of the first few generations. This paper investigates a recently proposed method for closing the CFD model by application of physiologically correct boundary conditions at truncated outlets. A realistic, reduced geometry model of the lung airway based on CT data has been constructed up to generation 18, including extrathoracic, bronchi, and bronchiole regions. Results indicate that the new method yields reasonable results for pressure drop through the airway, at a small fraction of the cost of fully resolved simulations.

A preliminary development of the Re-Injury Anxiety Inventory (RIAI).

OBJECTIVES: The present paper outlines the initial development of an instrument to measure re-injury anxiety. METHODS: Face, content and factorial validity were examined over three stages of exploratory factor analyses. PARTICIPANTS: 248 injured sport participants completed the scale. RESULTS: A 28-item measure was produced to measure re-injury anxiety, comprising of two factors: re-injury anxieties regarding rehabilitation (RIA-R: 15 items) and re-injury anxieties regarding returning to training/competition (RIA-RE: 13 items). These two factors accounted for 80.56% of the total variance. The internal consistency for both factors was above the .70 criterion value; rehabilitation re-injury anxiety (alpha=.98); re-entry into competition re-injury anxiety (alpha=.96). CONCLUSIONS: Future research needs to test the proposed 2-factor model presented in the current research using confirmatory factor analysis.
