- Description: Little is known about how to promote physical activity in single-parent families. We evaluated physical activity, barriers to physical activity and social connectedness changes in single-parent families following a one year YMCA programme. At baseline, 106 single parents completed a survey about physical activity, barriers to activity and social connectedness. Sixty-four parents provided data after 12 months. Self-reported minutes of physical activity per week decreased over the 12 months (p < 0.05). However, perceptions of activity over the 12 months increased 44% for parents and 66% for children. Family-related barriers that decreased following the programme included a lack of time and affordability of existing opportunities. Compared with their baseline responses, parents at 12 months showed an increased frequency of visits with friends (p < 0.05). Difficulties in recruiting and retaining single parents to complete the evaluation are testimony to the current poor understanding of the leisure needs of single-parent families. The results provide direction for future research.

- Description: Background: To commence injury prevention efforts, it is necessary to understand the magnitude of the injury problem. No systematic reviews have yet investigated the extent of injuries in field hockey, despite the popularity of the sport worldwide. Objective: Our objective was to describe the rate and severity of injuries in field hockey and investigate their characteristics. Methods: We conducted electronic searches in PubMed, Embase, SPORTDiscus, and CINAHL. Prospective cohort studies were included if they were published in English in a peer-reviewed journal and observed all possible injuries sustained by field hockey players during the period of the study. Results: The risk of bias score of the 22 studies included ranged from three to nine of a possible ten. In total, 12 studies (55%) reported injuries normalized by field hockey exposure. Injury rates ranged from 0.1 injuries (in school-aged players) to 90.9 injuries (in Africa Cup of Nations) per 1000 player-hours and from one injury (in high-school women) to 70 injuries (in under-21 age women) per 1000 player-sessions. Studies used different classifications for injury severity, but—within studies—injuries were included mostly in the less severe category. The lower limbs were most affected, and contusions/hematomas and abrasions were common types of injury. Contact injuries are common, but non-contact injuries are also a cause for concern. Conclusions: Considerable heterogeneity meant it was not possible to draw conclusive findings on the extent of the rate and severity of injuries. Establishing the extent of sports injury is considered the first step towards prevention, so there is a need for a consensus on injury surveillance in field hockey. © 2018, The Author(s).

- Description: Background: The potential of whole-body vibration (WBV) as a mode of dyspnoea free physical activity for people with chronic obstructive pulmonary disease (COPD) is unknown among community-based settings. Furthermore, the acute effects of WBV on people with COPD have not been profiled in community-based settings. The aim of this community-based proof-of-concept trial was to describe acute effects of WBV by profiling subjective and objective responses to physical activity. Findings. Seventeen community-dwelling older adults with COPD were recruited to participate in two sessions; WBV and sham WBV (SWBV). Each session consisted of five one-minute bouts interspersed with five one-minute passive rest periods. The gravitational force was ~2.5 g for WBV and ~0.0 g for SWBV. Reliability of baseline dyspnoea, heart rate, and oxygen saturation was first established and then profiled for both sessions. Acute responses to both WBV and SWBV were compared with repeated measures analysis of variance and repeated contrasts. Small changes in dyspnoea and oxygen saturation lacked subjective and clinical meaningfulness. One session of WBV and SWBV significantly increased heart rate (p ≤ 0.02), although there was no difference among WBV and SWBV (p = 0.67). Conclusions: This community-based proof-of-concept trial showed that a session of WBV can be completed with the absence of dyspnoea for people with COPD. Furthermore, there were no meaningful differences among WBV and SWBV for heart rate and oxygen saturation. There is scope for long-term community-based intervention research using WBV given the known effects of WBV on peripheral muscle function and functional independence.

- Description: Eccentric contractions that provide spring energy can also cause muscle damage. The aim of this study was to explore leg and vertical stiffness following muscle damage induced by an eccentric exercise protocol. Twenty active males completed 60 minutes of backward-walking on a treadmill at 0.67 m/s and a gradient of − 8.5° to induce muscle damage. Tests were performed immediately before; immediately post; and 24, 48, and 168 hours post eccentric exercise. Tests included running at 3.35 m/s and hopping at 2.2 Hz using single- and double-legged actions. Leg and vertical stiffness were measured from kinetic and kinematic data, and electromyography (EMG) of five muscles of the preferred limb were recorded during hopping. Increases in pain scores (over 37%) occurred post-exercise and 24 and 48 hours later (p < 0.001). A 7% decrease in maximal voluntary contraction occurred immediately post-exercise (p = 0.019). Changes in knee kinematics during single-legged hopping were observed 168 hours post (p < 0.05). No significant changes were observed in EMG, creatine kinase activity, leg, or vertical stiffness. Results indicate that knee mechanics may be altered to maintain consistent levels of leg and vertical stiffness when eccentric exercise-induced muscle damage is present in the lower legs. © 2014 Taylor & Francis.

- Description: Sport is a common context for injury. It is the most common reason for hospital-treated injury in adolescents and young adults and there is some evidence that injury rates at the population level are increasing. Sports injuries can occur to participants across all forms of sport ranging from elite/professional sport to competitive sport in clubs/colleges/schools to school sport to a range of fitness and physical activity programs usually undertaken for health and social reasons. Over recent years, evidence has accumulated that the majority of these injuries should be preventable if sports injury interventions are successfully implemented. The challenge remains to demonstrate the effectiveness of many sports injury interventions in appropriate real-world settings and to better understand the drivers and barriers to sports injury prevention implementation efforts. © 2014 Elsevier Inc.

- Description: Downhill backwards walking causes repeated, cyclical loading of the muscle-tendon unit. The effect this type of repeated loading has on the mechanical behaviour of the Achilles tendon is presently unknown. This study aimed to investigate the biomechanical response of the Achilles tendon aponeurosis complex following a downhill backwards walking protocol. Twenty active males (age: 22.3 +/- 3.0years; mass: 74.7 +/- 5.6kg; height: 1.8 +/- 0.7m) performed 60min of downhill (8.5 degrees), backwards walking on a treadmill at -0.67m center dot s(-1). Data were collected before, immediately post, and 24-, 48- and 168-h post-downhill backwards walking. Achilles tendon aponeurosis elongation, strain and stiffness were measured using ultrasonography. Muscle force decreased immediately post-downhill backward walking (P=0.019). There were increases in Achilles tendon aponeurosis stiffness at 24-h post-downhill backward walking (307 +/- 179.6N center dot mm(-1), P=0.004), and decreases in Achilles tendon aponeurosis strain during maximum voluntary contraction at 24 (3.8 +/- 1.7%, P=0.008) and 48h (3.9 +/- 1.8%, P=0.002) post. Repeated cyclical loading of downhill backwards walking affects the behaviour of the muscle-tendon unit, most likely by altering muscle compliance, and these changes result in tendon stiffness increases.

- Description: Background: Team bat-or-stick sports, including cricket, softball and hockey, are popular among women. However, little is known about the injury profile in this population. Objective: The aim was to describe the incidence, nature and anatomical location of injuries in bat-or-stick sports played by women in a competitive league. Methods: This review was prospectively registered (PROSPERO CRD42015026715). CINAHL, MEDLINE, PsycINFO, PubMed, SPORTDiscus were systematically searched from January 2000 to September 2016, inclusive. Peer-reviewed original research articles reporting the incidence, nature and anatomical location of injuries sustained by women aged 18 + years in competitive bat-or-stick sports were included. Two meta-analyses based on injury incidence proportions (injury IP) and injury rates per 1000 person-days of athletic exposure (AE) were performed. Results: A total of 37 studies satisfied the inclusion criteria, and five had low risk of bias. The weighted injury IP was 0.42 [95% confidence interval (CI) 0.39–0.45]. The weighted injury rate was 6.12 (95% CI 6.05–6.18) overall, and greater in games [15.79 (95% CI 15.65–15.93)] than in practice [3.07 (95% CI 2.99–3.15)]. The ankle was the most commonly injured anatomical location, followed by the hand (including wrist and fingers), knee and head. Soft tissue and ligament injuries were most common types of injuries. Conclusion: Injury prevention in women’s sports is a novel and emerging field of research interest. This review highlights that injury incidence is high among female bat-or-stick players, but little information is known about direct causal mechanisms. This review clearly establishes the need for enhancements to injury data collection. Without this information, it will not be possible to develop evidence-based injury prevention interventions. © 2017, Springer International Publishing AG, part of Springer Nature.

- Description: Objectives: To present the first comprehensive epidemiological profile of hospital-treated injuries sustained by female cricketers from 2002-2003 to 2013-2014 in Victoria, Australia. Design: Analysis of routinely collected hospital data (detailed case-series). Methods: A retrospective analysis of hospital-treatment data associated with cricket injuries sustained by women between 1 July 2002 and 30 June 2014, inclusive were extracted from databases held by the Victorian Injury Surveillance Unit in Australia. Results: Over the 12-year period, 668 cases were treated in Victoria. Of these, 547 were emergency department (ED)-presentations. There were 121 hospital-admissions, of which, the length of stay was <2 days for 78.5% cases. All cases were treated and released, and no fatalities were reported. The 10-14 year age group most frequently presented to ED (19.9%) and were most commonly admitted to hospital (16.5% of the total admissions). Fractures were the most common cause of hospital-admissions (47.1%) but only accounted for 17.2% of the ED-presentations. Dislocations, sprains and strains, were the most common (36.4%) cause of ED-presentations. The head was the most commonly injured anatomical location (27.8% of ED-presentations and 28.1% of hospital-admissions), followed by the wrist and hand (27.8% ED-presentations and 17.4% hospital-admissions). Conclusions: These findings provide the first overview of the nature of injuries requiring hospital attendance in female cricketers, and a foundation to inform the development of targeted injury prevention programs for female cricketers.

- Description: Objectives: Incidence, prevalence, nature, severity and mechanisms of injury in elite female cricketers over two seasons from March 2014 to March 2016, inclusive. Design: Prospective cohort study. Methods: Injury data collected via Cricket Australia's Athlete Management System on all elite female players over two seasons were analysed. Profiles of the nature, anatomical location and mechanism of injuries were presented according to dominant player position. Injury incidence rates were calculated based on match playing hours. Results: There were 600 medical-attention injuries; with 77.7% players reporting ≥1 injury. There were 79.5% acute injuries compared to gradual onset injuries. Of the all medical-attention injuries, 20.2% led to time-loss; 34.7% were match-time-loss injuries. Match injury incidence was 424.7 injuries/10,000 h for all injuries and 79.3 injuries/10,000 h for time-loss injuries. Of all the injuries, 31.8% were muscle injuries and 16.0% joint sprains. Wrist and hand (19.8%), lumbar spine (16.5%) and knee (14.9%) injuries were the most common time-loss injuries. Six players sustained lumber spine bone stress injury that resulted in the most days missed due to injury (average 110.5 days/injury). Conclusions: There is a need to focus on specific injuries in female cricket, including thigh, wrist/hand and knee injuries because of their frequency, and lumbar spine injuries because of their severity.
