Wake after sleep onset and get up time were moderately longer (g = 0.61 [0.22;1.26]) and later (g = 0.62 [0.27;1.17]) before. Twenty20 matches compared to One-Day International matches respectively. Further, sleep duration significantly declined from pre-match to post-match during the multi-day Test format (p = 0.04, g= 0.75 [0.40;1.12]). Late alcohol consumption was significantly (p < 0.05) correlated with a decrease in total sleep time, regardless of match venue (home: rs (49) = -0.69; away: rs (27) = -0.57). During the away condition, an increase in age was significantly associated with longer wake after sleep onset durations (rs (13) = 0.52, p = 0.0003), while greater elite experience was significantly associated with longer total sleep time (rs (72) = 0.36, p = 0.02). The non-sleep medication group took significantly longer to fall asleep compared to the sleep medication group during the first week of the away condition (p = 0.02, g = 0.75 [0.25;1.26]) particularly on nights following transmeridian travel. Although not significant ( p > 0.05), Asian/Indian players had moderately longer sleep onset latencies (g = 1.07 [0.66;1.47]), wake after sleep onset durations (g = 0.86 [0.42;1.29]), and lower subjective sleep quality (g = 0.86 [0.46;1.26]) and morning freshness scores (g = 0.89 [0.47;1.27]) compared to Whites. Similarly, Black Africans had moderately lower subjective sleep quality scores compared to Whites (g = 0.71 [0.43;0.97]). Longer sleep onset latencies and shorter total sleep times were significantly (p < 0.05) associated with poorer One-Day International (rs (28) = -0.57) and Test (rs (12) = 0.59) batting performances respectively. Higher subjective sleep quality scores were significantly associated with better Twenty20 bowling economies (rs (8) = -0.52). Discussion: There was no evidence of poor pre-match sleep behaviour, irrespective of venue; however, the most apparent disruption to sleep occurred post-match (similar to that found in other team-sports). Most disparities in sleep between match venues existed post-travel, with better sleep behaviour observed during the home condition. The differences in sleep patterns found in all three match formats were expected given the variations in format scheduling and duration. Although sleep medication was shown to promote better sleep, its long-term effectiveness was limited. The results promote the implementation of practical strategies aimed to reduce bedtime light-emitting technology use, late evening alcohol consumption and muscle pain. Inter-individual sleep behaviour was found between player roles, age, experience level and race. Moderate associations existed between sleep and markers of batting performance, specifically for the longer, strategic formats of the game. Conclusion: The current study provided new insight of the sleep behaviour in elite South African cricket players during competition. Individualized sleep monitoring practices are encouraged, with specific supervision over older, less experienced players as well as the racial minorities and allrounders of the team. The poor post-match sleep behaviour, together with the sleep and performance correlations, provide ideal opportunities for future interventions to focus on match recovery and the use sleep monitoring as a competitive advantage.]]> Wed 12 May 2021 22:35:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:37671 A in exon 41 is the most prevalent LRRK2 variation which causes a substitution of glycine to serine in G2019S in the highly activated loop of its MAP kinase domain. The LRRK2 G2019S variant is the most common genetic determinant of Parkinson’s disease identified to date. This work focused on building accurate 3D models of the LRRK2 kinase domain, that were used for large-scale in silico docking against South African natural compounds from the South African Natural Compounds Database (SANCDB; https://sancdb.rubi.ru.ac.za/). Molecular docking was performed to identify compounds that formed interactions with the active site of the protein and had the lowest binding energy scores. Molecular dynamics simulations showed different movements of the protein-ligand complexes and behavioural difference of the wildtype and the variants, all three structures proved to be compact.

High levels of weekly sedentary behaviour and sitting time (302.60 ± 169.96 minutes) were reported. A weak, non-significant, positive correlation was found between total sedentary time and BMI (p>0.05, R2 = 0.1). A weak, non-significant, negative correlation was found between age and sedentary time (p>0.05, R2 = 0.002). More participants below 50 years were insufficiently active compared to above the age of 50 years. 1.7 to 2.6 years since diagnosis saw the greatest number of insufficiently active survivors and the category over 2.6 years since diagnosis saw the most active survivors. Most breast cancer survivors (71.10% & 82.05%) indicated being interested in and feeling capable of participating in an exercise programme (p>0.05, R2 = 0.72). The favoured preference for receiving physical activity advice was face-to-face with an exercise specialist at a cancer centre before treatment. Participation preferences included starting a programme immediately after treatment, in a home-based setting with one or two other people, where walking and a moderate exercise intensity were the preferred exercise type and level of intensity. Data collection occurred both immediately prior to (42% of participants) and during (56% of participants) the South African Covid-19 lockdown, so the results should be seen in light of this context. Conclusion: The current study is one of the first to explore physical activity rates and preferences of South African breast cancer survivors. As a group and individually these survivors were meeting public physical activity guidelines and engaging in the recommended weekly minutes. The high sitting time coupled with the high overweight and obesity levels highlight the need for positive behavioural changes including improved levels of physical activity and reduced sedentary behaviour. These changes need involvement from the numerous levels of society that affect health. Broad physical activity guidelines need to be developed not only to improve physical activity levels in breast cancer survivors but to work as a preventative measure by facilitating physical activity promotion in the general population. The findings of this study demonstrate that this group of South African breast cancer survivors is open to physical activity advice, to programmes and to improving physical activity levels.]]> Wed 12 May 2021 15:00:22 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42946 Wed 12 May 2021 14:59:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42918 Wed 12 May 2021 14:59:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41439 Wed 12 May 2021 14:58:15 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41467 Wed 12 May 2021 14:57:17 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41332 Wed 12 May 2021 14:56:24 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42024 Wed 12 May 2021 14:54:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42940 Wed 12 May 2021 14:54:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42812 Wed 12 May 2021 14:53:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41128 Wed 12 May 2021 14:51:15 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41036 Wed 12 May 2021 14:38:58 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42806 Wed 12 May 2021 14:38:27 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41447 Wed 12 May 2021 14:38:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42133 Wed 12 May 2021 14:36:35 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41377 Wed 12 May 2021 14:34:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42173 Wed 12 May 2021 14:32:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41484 Wed 12 May 2021 14:28:57 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42196 Wed 12 May 2021 14:25:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41496 Wed 12 May 2021 14:24:42 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42480 0:5 h Mpc-1.
