      Owen, Wendy (Tempus, 2005-06-01)
      This book is the autobiography of former English international footballer Wendy Owen. It discusses the rise of women's football in England after the success of the 1966 World Cup and how women's football was slowly accepted by the FA and society in general.
    • ‘Life in the Travelling Circus’: A Study of Loneliness, Work Stress, and Money Issues in Touring Professional Golf

      Fry, John; Bloyce, Daniel; Myerscough College; University of Chester (Human Kinetics, 2017-06-31)
      This article examines the effects of globalization on the well-being of migrant professional athletes. Interviews with 20 touring professional golfers reveal that players experience many of the personal problems – such as loneliness, isolation, low decision latitude, low social support, and effort-reward imbalance – which have been identified as “strong predictors of mental ill-health” (Leka & Jain, 2010, p. 65). Feelings of loneliness and isolation developed as players were regularly apart from family and friends, and spent most of their time with other golfers whom they had somewhat superficial relationships with. These feelings coupled with, for many, uncertain income generated through golf added further to their work-related anxieties. Overall, results highlight the importance of considering how workplace anxieties and vulnerabilities impact on athlete migrants’ health and well-being.
    • The link between knowledge and visual fixation in gymnastics coaching and judging: A case study approach

      Page, Jennifer L.; Lafferty, Moira E.; Wheeler, Timothy J.; University of Chester (2007-09)
      Whilst little information exists to explain how coaches and judges process observed movement into performance scores, it wouls seem logical to suggest that a relationship exists between attention and knowledge. This study examines the relationship between these phenomena by examining whether a relationship exists between visual fixation data and knowledge in gymnastic judging scenarios, using a two-phase case study design.
    • Local status and power in area-based health improvement partnerships

      Powell, Katie; Thurston, Miranda; Bloyce, Daniel; University of Sheffield ; Hedmark University College, Norway ; University of Chester (SAGE, 2014-04-01)
      Area-based initiatives (ABIs) have formed an important part of public policy towards more socio-economically deprived areas in many countries. Co-ordinating service provision within and across sectors has been a common feature of these initiatives. Despite sustained policy interest in ABIs, little empirical work has explored relations between ABI providers and partnership development within this context remains under-theorised. This paper addresses both of these gaps by exploring partnerships as a social and developmental process, drawing on concepts from figurational sociology to explain how provider relations develop within an ABI. Qualitative methods were used to explore, prospectively, the development of an ABI targeted at a town in the north west of England. A central finding was that, although effective delivery of ABIs is premised on a high level of coordination between service providers, the pattern of interdependencies between providers limits the frequency and effectiveness of cooperation. In particular, the interdependency of ABI providers with others in their organisation (what is termed here ‘organisational pull’) constrained the ways in which they worked with providers outside of their own organisations. ‘Local’ status, which could be earned over time, enabled some providers to exert greater control over the way in which provider relations developed during the course of the initiative. These findings demonstrate how historically constituted social networks, within which all providers are embedded, shape partnership development. The theoretical insight developed here suggests a need for more realistic expectations among policy makers about how and to what extent provider partnerships can be managed.

    • Low body fat does not influence recovery after muscle-damaging lower-limb plyometrics in young male team sport athletes

      Fernandes, John; Lamb, Kevin; Twist, Craig; University of Chester
      Aim: This study assessed the influence of fat mass to fat-free mass ratio (FM:FFM) on recovery from plyometric exercise. Method: After assessment of body composition, 20 male team sport players (age 20.7 1.1 years; body mass 77.1 11.5 kg) were divided into low- (n = 10; 0.11 0.03) and normal- (n = 10; 0.27 0.09) fat groups based on FM:FFM ratio. Thereafter, participants completed measurements of knee extensor torque at 60 and 240 s􀀀1, countermovement jump flight time, plasma creatine kinase (CK) activity and perceived muscle soreness (VAS) before and at 0, 24 and 48 h after 10 10 maximal plyometric vertical jumps. Results: Evidence of muscle damage was confirmed by alterations in VAS, peak torque at 60 and 240 s􀀀1 and flight time at 0, 24 and 48 h after plyometric exercise (P < 0.05). CK was increased at 0 and 24 h (P < 0.05) but returned to baseline values by 48 h. No time by group e ects were observed for any of the dependent variables (P > 0.05). Conclusion: The current findings indicate that while muscle damage was present after plyometric exercise, the magnitude was similar across the two body composition groups. Applied practitioners can allow for a similar recovery time after plyometric exercise in those with low and normal body fat.
    • Low Body Fat Does Not Influence Recovery after Muscle-Damaging Lower-Limb Plyometrics in Young Male Team Sport Athletes.

      Fernandes, John F T; Lamb, Kevin L; orcid: 0000-0003-4481-4711; Twist, Craig; orcid: 0000-0001-6168-0378 (2020-11-05)
      This study assessed the influence of fat mass to fat-free mass ratio (FM:FFM) on recovery from plyometric exercise. After assessment of body composition, 20 male team sport players (age 20.7 ± 1.1 years; body mass 77.1 ± 11.5 kg) were divided into low- ( = 10; 0.11 ± 0.03) and normal- ( = 10; 0.27 ± 0.09) fat groups based on FM:FFM ratio. Thereafter, participants completed measurements of knee extensor torque at 60 and 240°∙s , countermovement jump flight time, plasma creatine kinase (CK) activity and perceived muscle soreness (VAS) before and at 0, 24 and 48 h after 10 × 10 maximal plyometric vertical jumps. Evidence of muscle damage was confirmed by alterations in VAS, peak torque at 60 and 240°∙s and flight time at 0, 24 and 48 h after plyometric exercise ( < 0.05). CK was increased at 0 and 24 h ( < 0.05) but returned to baseline values by 48 h. No time by group effects were observed for any of the dependent variables ( > 0.05). The current findings indicate that while muscle damage was present after plyometric exercise, the magnitude was similar across the two body composition groups. Applied practitioners can allow for a similar recovery time after plyometric exercise in those with low and normal body fat.
    • Lower-volume muscle-damaging exercise protects against high-volume muscle-damaging exercise and the detrimental effects on endurance performance

      Burt, Dean G.; Lamb, Kevin L.; Nicholas, Ceri; Twist, Craig; University of Chester; Staffordshire University (Springer Verlag, 2015-02-21)
      Purpose: This study examined whether lower-volume exercise-induced muscle damage (EIMD) performed 2 weeks before high-volume muscle-damaging exercise protects against its detrimental effect on running performance. Methods: Sixteen male participants were randomly assigned to a lower-volume (five sets of ten squats, n = 8) or high-volume (ten sets of ten squats, n = 8) EIMD group and completed baseline measurements for muscle soreness, knee extensor torque, creatine kinase (CK), a 5-min fixedintensity running bout and a 3-km running time-trial. Measurements were repeated 24 and 48 h after EIMD, and the running time-trial after 48 h. Two weeks later, both groups repeated the baseline measurements, ten sets of ten squats and the same follow-up testing (Bout 2). Results: Data analysis revealed increases in muscle soreness and CK and decreases in knee extensor torque 24–48 h after the initial bouts of EIMD. Increases in oxygen uptake ˙V O2 , minute ventilation ˙V E and rating of perceived exertion were observed during fixed-intensity running 24–48 h after EIMD Bout 1. Likewise, time increased and speed and ˙V O2 decreased during a 3-km running time-trial 48 h after EIMD. Symptoms of EIMD, responses during fixed-intensity and running time-trial were attenuated in the days after the repeated bout of high-volume EIMD performed 2 weeks after the initial bout. Conclusions: This study demonstrates that the protective effect of lower-volume EIMD on subsequent high-volume EIMD is transferable to endurance running. Furthermore, time-trial performance was found to be preserved after a repeated bout of EIMD.
    • Marathon des Sables: A scientific case study

      Ryder, J. J.; Grantham, N. J.; Kellett, David; Jones, G. E.; University of Hull ; University College Chester ; University College Chester ; University College Chester ; University College Chester (Taylor & Francis, 2004-01)
      The Marathon des Sables is an ultra-endurance foot race across the Sahara Desert. The event lasts 6 days, and competitors are susceptible to a variety of specific injuries, including dehydration, heat stress, and ultimately poor performance. This study involved the monitoring of a highly trained 42-year-old male competitor through a 6-month training program and immediately after the event. The monitoring sessions assessed maximal oxygen uptake (VO2 Max), pulmonary function, anthropometric characteristics, body composition, resting metabolic rate, training, and nutritional status. The subject also completed a period of acclimation during the taper phase of the training program in an environmental chamber. The last pre-race VO2max of 4.5 1-min showed a decrease of 0.5 1-min. The subject's diet successfully maintained body weight during the training period, and the subject's weight increased from 67.7kg at 12.2% body fat to 71kg at 13.2% body fat during the taper. The subject sustained no chronic injuries during the training or race periods. We concluded that the intervention strategies adopted were successful in preparing the subject to successfully complete the Marathon des Sables. The athlete covered the 229km in 29hr 21min 21sec, finishing in 75th place.
    • Measurement procedures affect the interpretation of metatarsophalangeal joint function during accelerated sprinting

      Smith, Grace; Lake, Mark; Lees, Adrian; Worsfold, Paul R.; University of Chester ; Liverpool John Moores University ; Liverpool John Moores University ; University of Chester (Routledge, 2012-08-07)
      The metatarsophalangeal joint (MPJ) is a significant absorber of energy in sprinting. This study examined the influence of MPJ axis choice and filter cut-off frequency on kinetic variables describing MPJ function during accelerated sprinting. Eight trained sprinters performed maximal sprints along a runway. Three dimensional high-speed (1000 Hz) kinematic and kinetic data were collected at the 20 m point. Three axis definitions for the five MPJs were compared. MPJ moments, powers and energies were calculated using different filter cut-off frequencies. The more anatomically appropriate dual axis resulted in less energy absorbed at the MPJ compared to the oblique axis which also absorbed less energy compared to the perpendicular axis. Furthermore, a low cut-off frequency (8 Hz) substantially underestimated MPJ kinematics, kinetics and the energy absorbed at the joint and lowered the estimate of energy production during push-off. It is concluded that a better understanding of MPJ function during sprinting would be obtained by using an oblique or anatomically appropriate representation of the joint together with appropriate kinematic data sampling and filtering so that high frequency movement characteristics are retained.
    • Mental practice, motor performance, and the late CNV

      Smith, Dave; Collins, Dave; University College Chester ; University of Edinburgh (North American Society for the Psychology of Sport and Physical Activity, 2004-09)
      The aim of these two studies was to examine the application of Lang’s (1979, 1985) bioinformational theory to the mental practice (MP) of a strength task, the maximal voluntary contraction of the abductor digiti minimi, and the MP of a computerized barrier knockdown task. Study 1 divided 18 males into three groups: a physical practice (PP) group; a stimulus and response proposition mental practice (SRP) group; and a stimulus proposition mental practice (SP) group. Each participant either physically or mentally practiced 40 contractions twice a week for 3 weeks, and electroencephalograms (EEGs) were recorded during testing sessions. All three groups significantly increased abduction strength, but there were no significant between-group differences in the mag-nitude of the improvements. In addition, late contingent negative variation (CNV) waves were apparent prior to both real and imagined movements in all conditions. Study 2 allocated 24 participants to PP, SRP, SP, and control groups. Participants performed 120 imaginary or actual barrier knockdown trials, with EEGs recorded as in Study 1. A Group x Test ANOVA for movement time revealed that the PP and SRP groups improved to a significantly greater degree than the SP and control groups. Also, the late CNV was observed prior to real and imagined movement in the SRP group, but not prior to imagined movement in the SP group. These results support bioinformational theory with respect to cognitively oriented motor tasks, but not strength tasks.
    • Metabolic demands and replenishment of muscle glycogen after a rugby league match simulation protocol.

      Bradley, Warren J.; Hannon, Marcus P.; Benford, Victoria; Morehen, James C.; Twist, Craig; Shepherd, Sam; Cocks, Matthew; Impey, Samuel G.; Cooper, Robert G.; Morton, James P.; et al. (2017-02-22)
      Objectives: The metabolic requirements of a rugby league match simulation protocol and the timing of carbohydrate provision on glycogen re-synthesis in damaged muscle were examined. Design: Fifteen (mean ± SD: age 20.9 ± 2.9 y, body-mass 87.3 ± 14.1 kg, height 177.4 ± 6.0 cm) rugby league (RL) players consumed a 6 g•kg•day-1 CHO diet for 7-days, completed a time to exhaustion test (TTE) and a glycogen depletion protocol on day-3, a RL simulated-match protocol (RLMSP) on day-5 and a TTE on day-7. Players were prescribed an immediate or delayed (2-h-post) re-feed post-simulation. Methods: Muscle biopsies and blood samples were obtained post-depletion, before and after simulated match-play, and 48-h after match-play with PlayerLoad and heart-rate collected throughout the simulation. Data were analysed using effects sizes ± 90% CI and magnitude-based inferences. Results: PlayerLoad (8.0 ± 0.7 AU•min-1) and %HRpeak (83 ± 4.9%) during the simulation were similar to values reported for RL match-play. Muscle glycogen very likely increased from immediately after to 48-h post-simulation (272 ± 97 cf. 416 ± 162 mmol•kg-1d.w.; ES ± 90%CI) after immediate re-feed, but changes were unclear (283 ± 68 cf. 361 ± 144 mmol•kg-1d.w.; ES ± 90%CI) after delayed re-feed. CK almost certainly increased by 77.9 ± 25.4% (0.75 ± 0.19) post-simulation for all players. Conclusions: The RLMSP presents a replication of the internal loads associated with professional RL match-play, although difficulties in replicating the collision reduced the metabolic demands and glycogen utilisation. Further, it is possible to replete muscle glycogen in damaged muscle employing an immediate re-feed strategy.
    • Metatarsophalangeal joint function during sprinting: A comparison of barefoot and sprint spike shod foot conditions

      Smith, Grace; Lake, Mark; Lees, Adrian; University of Chester ; Liverpool John Moores University ; Liverpool John Moores University (2013-09-13)
      The metatarsophalangeal joint is an important contributor to lower limb energetics during sprint running. This study compared the kinematics, kinetics and energetics of the metatarsophalangeal joint during sprinting barefoot and wearing standardised sprint spikes. The aim of this investigation was to determine whether standard sprinting footwear alters the natural motion and function of the metatatarsophalangeal joint exhibited during barefoot sprint running. Eight trained sprinters performed maximal sprints along a runway, four sprints in each condition. Three dimensional high speed (1000 Hz) kinematic and kinetic data were collected at the 20 m point. Joint angle, angular velocity, moment, power and energy were calculated for the metatarsophalangeal joint. Sprint spikes significantly increase sprinting velocity (0.3 m/s average increase), yet limit the range of motion about the metatarsophalangeal joint (17.9 % average reduction) and reduce peak dorsiflexion velocity (25.5 % average reduction), thus exhibiting a controlling affect over the natural behaviour of the foot. However, sprint spikes improve metatarsophalangeal joint kinetics by significantly increasing the peak metatarsophalangeal joint moment (15 % average increase) and total energy generated during the important push-off phase (0.5 J to 1.4 J). The results demonstrate substantial changes in metatarsophalangeal function and potential improvements in performance-related parameters due to footwear.
    • Misperception: No evidence to dismiss RPE as regulator of moderate-intensity exercise

      Eston, Roger; Coquart, J.; Lamb, Kevin L.; Parfitt, Gaynor; University of South Australia; Universite´ de Rouen; University of Chester (American College of Sports Medicine, 2015-12-01)
      Dear Editor-in-Chief, Shaykevich et al. (7) demonstrate the efficacy of auditory feedback anchored at 75% of age-predicted HRmax to regulate intensity (claimed as ‘‘moderate’’) during several 20-min bouts of cycling. Their technical approach is novel, but 76% HRmax is the upper limit of moderate intensity, so given the large error in age-predicted HRmax, it is unlikely that their exercise bandwidth was ‘‘moderate’’ for all participants. This is not our major concern, but it reveals one among other inaccuracies: the most serious include training, interpretation, and inferences relating to the RPE.
    • Mission impossible? Reflecting upon the relationship between physical education, youth sport and lifelong participation

      Green, Ken; University of Chester (Taylor & Francis, 2012-05-08)
      It is widely believed that school physical education (PE) is or, at the very least, can (even should) be a crucial vehicle for enhancing young people’s engagement with physically active recreation (typically but not exclusively in the form of sport) in their leisure and, in the longer run, over the life-course. Despite the prevalence of such beliefs there remains a dearth of evidence demonstrating a ‘PE effect’. Indeed, the precise nature of the relationship between PE, youth sport and lifelong participation is seldom explored other than in implicit, often speculative and discursive, ways that simply take-for-granted the positive effects of the former (PE) on the latter (youth and adult participation in sport and physically active recreation). Using largely European studies to frame the issue, this paper reflects upon the supposedly ‘causal’ relationship between PE, youth sport and lifelong participation and, in doing so, highlights the inherent problems associated with attempts to identify, characterise and establish a ‘PE effect’.
    • More than a game? The role of sports governing bodies in the development of sport education programmes

      Reid, Paul; University College Chester (SAGE, 2003-10-01)
      This article explores the extent to which young people can transfer the skills and knowledge gained from a sport education programme to contexts experienced outside the curriculum. Furthermore, it seeks to identify how and where governing bodies of sport can be influential in the promotion of sport education values outside the school context; that is to say, are governing bodies able to develop initiatives to encourage community clubs to adopt a supporting role in the promotion and delivery of sport education?
    • The movement and physiological demands of international and regional men's touch rugby matches

      Beaven, Robert; Highton, Jamie M.; Thorpe, Cari; Knott, Emma; Twist, Craig; University of Chester; Manchester Metropolitan University; Huddersfield University (Lippincott, Williams & Wilkins, 2014-05-14)
      This study compared the internal and external match demands imposed on international and regional standard male touch rugby players. The study adopted a cohort design with independent groups. Twelve international players (mean age 27.8 ± 6.2 y, body mass 72.8 ± 3.7 kg, stature 174.5 ± 5.4 cm) and nine regional players (mean age 25.5 ± 5.5 y, body mass 74.2 ± 7 kg, stature 174.1 ± 7 cm) were analysed during nine competitive matches from the 2013 season. Movement demands were measured using a 5 Hz global positioning system (GPS), alongside heart rate and session rating of perceived exertion (s-RPE) to quantify internal load. Total distance covered by international players was lower than regional players (2265.8 ± 562.3 cf. 2970 ± 558.9 m, p<0.05). However, international players had greater relative distance (137.1 ± 13.6 cf. 126.2 ± 17.2 m·min) due to shorter playing times per match (p<0.05). Absolute high speed running (>14 km·h) was not different between groups (p>0.05), but relative high speed running (39.3 ± 12.0 cf. 26.0 ± 13.6 m·min) was higher for international players. Regional players performed more absolute low speed activity (≤14 km·h) than international players (p<0.05), whereas relative low speed activity was not different between groups (p>0.05). Very high speed running (>20 km·h) distance, bout number and frequency, peak and average speed were all greater in international players (p<0.05). Higher average heart rate, summated heart rate and s-RPE (p<0.05) indicated higher internal loads during matches for regional players. These data indicate that performance in men's touch rugby is characterised by more relative high speed running and better repeated sprint capacities in higher standard players.
    • Movement characteristics, physiological and perceptual responses of elite standard youth football players to different high intensity running drills

      Gibson, Neil; Henning, Greig; Twist, Craig; Heriot-Watt University; University of Chester (Taylor & Francis, 2018-04-06)
      Purpose: To examine responses to high intensity running drills in youth football players. Methods: Seventeen players completed the YoYo Intermittent Recovery test level one (YYIR1) and a 15 m maximal sprint to quantify target running speeds. Players performed three conditions on separate occasions comprising: 12 x 15 s high intensity runs at 100% of the final YYIRT1 speed, 12 x ~4 s repeated sprints with ~26 s recovery, and combination running using both modalities. Heart rate was monitored continuously with PlayerLoadTM and movement characteristics using microtechnology. Ratings of perceived exertion and blood lactate responses were measured 2 min after the final repetition. The ratio of Flight:contraction time was calculated from a countermovement jump before and at 2 min and 14 hours after each condition. Data analysis used magnitude based inferences and effect sizes statistics. Results: Peak speed (1.1%; ES 0.23 ± 0.44) and mean speed over the initial 4s (6.3%; ES 0.45 ± 0.46) were possibly faster during combination compared to high intensity running with unclear differences when compared to repeated sprinting. This was despite most likely (21.6%; ES 7.65 ± 1.02) differences in prescribed speeds between conditions. There were likely reductions in F:C at 14 hours ratio after high intensity (-5.6%; ES –0.44 ± 0.32) and combination running (-6.8%; ES -0.53 ± 0.47). Changes in the repeated sprinting condition were unclear. Conclusions: Actual movement characteristics of high intensity running drills may not reflect those used to prescribe them whilst reductions in F:C ratio are still evident 14 hours after their completion.

    • Moving primary physical education forward: start at the beginning

      Jess, Mike; McEvilly, Nollaig; Carse, Nicola; The University of Edinburgh; University of Chester; The University of Edinburgh (Taylor & Francis, 2016-03-07)
      This paper presents selected findings from a questionnaire completed by 509 primary school teachers in Scotland. Drawing on policy enactment theory, the paper focusses on teachers’ personal experiences of physical education and perceptions of the importance of physical education in their schools. More than half (56%) reported that physical education was either ‘very important’ or ‘important’, while almost 40% perceived it to be of ‘limited’ or ‘very limited importance’. ‘Staff’, ‘time’ and ‘subject status’ were the main themes they drew on to explain their responses. Our findings highlight the diverse nature of the physical education professional cultures in Scottish primary schools. From this, we propose that future initiatives to support change in primary physical education should, as a starting point, acknowledge these diverse professional cultures and move beyond the simplistic one-size-fits-all change projects that have been shown to have limited impact on practice.
