The effectiveness of exercise interventions to increase physical activity in Cystic Fibrosis: A systematic review.

Physical activity (PA) and exercise have numerous benefits in Cystic Fibrosis (CF) including improved lung function, exercise capacity and quality of life. Despite these benefits, the effectiveness of interventions to promote PA in this population are still largely unknown. The objective of this review was to synthesise existing research and determine whether exercise interventions are effective in promoting PA in people with CF. Using the PRISMA guidelines, a comprehensive search was conducted. Fifteen studies (463 participants) met the inclusion criteria. Eleven studies demonstrated improvements in PA in both short- and long-term interventions. However, the interventions were variable across the included studies, with a large inconsistency in PA assessment tools used. Aerobic training and activity counselling were the two elements identified in this review which most consistently improved PA. Future research should consider larger sample sizes and the use of accurate instruments to assess and track PA levels longitudinally.

General health complaints and sleep associated with new injury within an endurance sporting population: A prospective study.

OBJECTIVES: To examine the association between subjective health complaints, sleep quantity and new injury within an endurance sport population. DESIGN: Prospective cohort study. METHODS: Ninety-five endurance sporting participants were recruited from running, triathlon, swimming, cycling and rowing disciplines. Over 52-week period participants submitted weekly data regarding subjective health complaints (SHCs) (cardiorespiratory, gastrointestinal and psychological/lifestyle), sleep quantity, training load and new injury episodes. Applying a 7- and 14-day lag period, a shared frailty model was used to explore new injury risk associations with total SHCs and sleep quantity. RESULTS: 92.6% of 95 participants completed all 52 weeks of data submission and the remainder of the participants completed ≥30 weeks. Seven-day lag psychological/lifestyle SHCs were significantly associated with new injury risk (Hazard ratio (HR)=1.32; CI 95%=1.01-1.72, p<0.04). In contrast, cardiorespiratory (HR=1.15; CI 95%=0.99-1.36, p=0.07) and gastrointestinal (HR=0.77; CI 95%=0.56-1.05, p=0.09) SHCs were not significantly associated with new injury risk. New injury risk had a significant increased association with 14-day lag <7h/day sleep quantity (HR=1.51; CI 95%=2.02-1.13, p<0.01) and a significant decreased association with >7h/day sleep quantity (HR=0.63, CI 95%=0.45-0.87, p<0.01. A secondary regression analysis demonstrated no significant association with total SHCs and training load factors (Relative Risk (RR)=0.08, CI 95%=0.04-0.21, p=0.20). CONCLUSIONS: To minimise an increased risk of new injuries within an endurance sporting population, this study demonstrates that psychological/lifestyle subjective health complaints and sleep quantity should be considered. The study also highlights a lag period between low sleep quantity and its subsequent impact on new injury risk. No association was demonstrated between subjective health complaints, sleep quantity and training load factors.

The associations between training load and baseline characteristics on musculoskeletal injury and pain in endurance sport populations: A systematic review.

OBJECTIVES: To determine the associations between training load, baseline characteristics (e.g. age or previous injury) and rate of musculoskeletal injury and/or pain specifically within an Endurance Sporting Population (ESP). DESIGN: Prospectively registered systematic review. METHODS: Eight electronic databases were searched by two independent reviewers. Studies were required to prospectively monitor both (i) training loads and (ii) musculoskeletal injury and/or pain for >3 months. Methodological quality and risk of bias were determined utilising the Critical Skills Appraisal Program (CASP). Reported effect sizes were categorised as small, medium or large. RESULTS: Twelve endurance sport studies were eligible (running, triathlon, rowing). Increased injury and/or pain risk was associated with: (i) high total training distances per week/month (medium effect size) (ii) training frequency <2 sessions/week (medium effect size) and (iii) both low weekly (<2hours/week) and high monthly (large effect size) training durations. None of the studies reported internal training load data or acute:chronic workload ratios. Baseline characteristics found to increase the rate of injury and/or pain included: (i) a history of previous injury (medium effect size), (ii) age >45 years (small effect size), (iii) non-musculoskeletal comorbidities (large effect size), (iv) using older running shoes (small effect size) and (v) non-competitive behaviour. CONCLUSIONS: This review identifies a range of external training load factors and baseline characteristics associated with an increased rate of injury and/or pain within ESPs. There is an absence of research relating to internal training loads and acute:chronic workload ratios in relation to rate of injury and/or pain within ESPs.

The impact of spinal cord injury on the quality of life of primary family caregivers: a literature review.

STUDY DESIGN: Literature review. OBJECTIVES: To provide a detailed review of the literature regarding the impact of spinal cord injury (SCI) on the quality of life (QOL) of family members who have become the primary caregiver and to highlight potential interventions available. METHODS: Appropriate databases were searched for relevant peer-reviewed studies. Twenty-five studies (four qualitative and 21 quantitative) were identified which investigated the role that family members play in caring for people with SCI and the impact it has on their QOL. RESULTS: Depression, anxiety, physical symptoms and reduced satisfaction with life in primary family caregivers of patients with SCI were commonly reported across the literature. Isolation, loss of identity and role changes were also regularly reported as negative outcomes of caregiving for someone with an SCI. A range of interventions (including family training, problem-solving training and support groups) have been shown to have benefits for family caregivers' QOL. CONCLUSION: SCI impacts significantly on the QOL of family caregivers, with major implications for physical, mental and social aspects of caregiver health. This review highlights that these important issues are problematic internationally and may persist over several decades. The need for focused interventions to support family caregivers of spinal cord injured persons, with particular emphasis on increasing patient/family education and access to support groups, is recommended.

Inability to perform because of pain/injury in elite adult Irish dance: A prospective investigation of contributing factors.

Previous research in Irish dancing (ID) has recorded high levels of pain/injury. Screening protocols in other genres have been developed to identify at-risk dancers. The aims of the study were to examine the factors that relate to absence from dancing because of musculo-skeletal pain/injury in ID, and to inform guidelines for the development of an evidence-based screening protocol. Baseline subjective data (n = 85) and physical data (n = 84) were gathered. Subjects completed a monthly online questionnaire for 1 year providing data on general physical and psychological health and rates of pain/injury. Subjects were allocated to a "More Time Absent (MTA)" or "Less Time Absent (LTA)" category depending on their duration of absence from performance over the year. Eighty-four subjects completed the year-long follow-up (MTA: n = 32; LTA: n = 52). Two hundred seventy-eight complaints of pain/injury were recorded. Factors significantly associated with membership of the MTA group included greater anger-hostility (P = 0.003), more subjective health complaints (P = 0.026), more severe previous pain/injury (P = 0.017), more general everyday pain (P = 0.020), more body parts affected by pain/injury (P = 0.028), always/often dancing in pain (P = 0.028), and insufficient sleep (P = 0.043). Several biopsychosocial factors appear to be associated with absence from ID because of pain/injury. Biopsychosocial screening protocols and prevention strategies may best identify at-risk dancers.
