Nurse facilitated 5000 m running at Parkrun improves vulnerable adolescent health in a high deprivation area: A matched pair randomized control trial.

OBJECTIVE: To examine the effect of weekly nurse facilitated 5000 m running at Parkrun on markers of health in vulnerable adolescents from a high deprivation area. DESIGN: A matched pair randomized control trial. SAMPLE: Twenty-five adolescents aged 13-18, 90% identifying as Maori/Pasifika ethnicity. INTERVENTION: The intervention (INT) group participated in 6-10 Parkruns within 10 weeks, and a control group (CON) participated in one Parkrun only. A nurse facilitated the intervention offering support and encouragement at each Parkrun. MEASUREMENTS: Pre- and post-intervention testing sessions for cardiorespiratory fitness (CRF), glycated hemoglobin, body mass index (BMI), skeletal muscle mass (SMM), body fat, and hand grip strength (STR) were conducted. RESULTS: Parkrun improved CRF (F = 5.308, p = 0.035) and 5000 m time (t = 2.850, p = 0.019) by 5.5 ± 4.9 min (11.2%). Parkrun conferred a large beneficial effect on CRF (η2 = 0.249) a moderate beneficial effect on glycated hemoglobin levels (η2 = 0.119), and small beneficial effects upon SMM (η2 = 0.037) and body fat (η2 = 0.017). CONCLUSION: A weekly dose of nurse facilitated Parkrun can be recommended as a simple, accessible intervention that confers multiple beneficial effects on markers for health in adolescents from a high deprivation area.

Physical, functional and personal variables affecting shoulder complaints in healthcare workers.

BACKGROUND: Work-related shoulder disorders adversely affect the quality of life and lead to increased costs related to decreased productivity and injury treatment. Therefore, understanding the relationship between strength, upper extremity function and work ability contributes to the development of interventions aimed to improve the well-being of healthcare workers. OBJECTIVE: Correlate shoulder abduction and handgrip strength with upper extremity function and work ability in healthcare workers with shoulder complaints. METHODS: 67 workers with shoulder pain in the last year were assessed by Disability of Arm, Shoulder and Hand (QuickDASH), Work Ability Index (WAI), isokinetic shoulder strength and isometric handgrip strength dynamometers. Data were analysed with Spearman's Correlation Coefficient (ρ= 0.05), SPSS 20.0®. RESULTS: 52% males, mean age 48.4 years, 42% physically active, most administrative and general services workers. Low correlation between handgrip strength and QuickDASH (r=-0.359; p = 0.004); low correlation between handgrip strength and WAI (r = 0.359; p = 0.003) and between shoulder abduction strength and the QuickDASH (r = -0.267; p = 0.049); no significant correlation between shoulder abduction strength and WAI (r = 0.001; p = 0.997). CONCLUSIONS: Handgrip and shoulder abduction strength were inversely associated with upper extremity dysfunction. Shoulder abduction strength was associated with work ability. The inclusion of strength assessment in workers is important to guide strategies to prevent musculoskeletal disorders.
