Item The relationship between work stress and years of experience amongst male mental health care practitioners within tertiary psychiatric hospitals in the uMgungundlovu Health District(2020-11-30) Smith, Mark Albert; Orton, Penelope; Adams, CarolPsychiatric nursing is a speciality within the nursing profession in which the nurse directs his or her efforts to the early identification of and intervention in emotional problems and work towards the promotion of mental health. In addition, effort is placed on the prevention of mental disturbances, and follow - up care to minimize long - term effects of mental disturbance (Uys and Middleton, 2014:18-20). According to the South African Depression and Anxiety Group (SADAG) (2015), 16.5% of South Africans suffer from common mental disorders like depression and anxiety. Even more concerning is the fact that 17% of children and adolescents suffer from mental disorders. Mental illness adversely affects the person’s brain and at times requires long-term treatment. In this study a total of 158 male mental health care nurse practitioners’ were questioned and a quantitative non- experimental cross sectional descriptive survey was conducted to describe male mental health care nurse’s practitioners’ years of experience in psychiatric nursing and the levels of stress of these nurses was identified. The researcher also determined whether there was any relationship between the stress reported and the years of experience amongst male mental health care nursing practitioners in tertiary psychiatric hospitals in Pietermaritzburg.Item The effect of core stability on male water polo players’ jump height and throwing velocity(2020-11-30) McKenzie, Nicole Ashley; Matkovich, GrantBACKGROUND Water polo is a highly competitive and physical sport where athletes are continuously looking for ways to improve their performance and reduce injuries. Core stability has been extensively studied in its role to improve athletic performance and to reduce the risk of injuries in overhead throwing athletes. AIM To determine the role of core stability in male water polo players’ by identifying the relationship between core stability, jump height and throwing velocity. OBJECTIVES To measure core stability, jump height (cm) and throwing velocity (km/h) in male water polo players and to identify if any correlations exist between them. METHOD Core stability was assessed in twenty-six asymptomatic male water polo athletes using the PRONE and SUPINE tests. Participants jump height (cm) and throwing velocity (km/h) were measured using a modified yard stick and speed radar gun. IBM SPSS version 24 was used to analyse the data. A probability (p) value less than 0.05 was considered statistically significant. RESULTS The mean values for jump height were calculated at maximum head height (64.22 cm) and head height at ball release (59.50 cm) respectively. Throwing velocities ranged from 50.33 km/h to 77.33 km/h. There was a significant relationship between: core stability and maximum head height (p=0.027), head height at ball release (p=0.025) and throwing velocity (p=0.001). Significant correlations were depicted among the three outcome measures. The strongest relationship was between maximum head height and head height at ball release (r = 0.945). CONCLUSION The results of this study show that core stability significantly affects throwing velocity and jump height in water polo athletes with the largest difference being between moderate and excellent core stability.
