EFFECTS OF PURTURBATIONS ON KICKING LIMB CO-ORDINATION DURING THE SEPAKTAKRAW SERVE – A PRELIMINARY ANALYSIS WITH COACHING IMPLICATIONS

The purpose of this study was to describe kicking limb joint co-ordination between sepaktakraw serve techniques and to establish the effects of a perturbation on joint co-ordination when executing serve skills of different complexity to determine if the intended perturbations are required during training. A total of 25 kuda and 25 sila serve trials, performed by a trained male sepaktakraw player, were captured using a high-speed optical camera system. Kicking limb joint co-ordination differs between technique possibly due to differences in kicking kinematics. When subjected to perturbations (not receiving an ideal ball position in mid-air because the ball is tossed by another player), it took a longer time to return to normal kuda kicking patterns. Even with perturbations, players made adaptations to the kicking limb co-ordination and this strategy is key for repeated successful serves to unknown ball tossed positions in mid-air for optimal performance outcome measures. It is therefore recommended that perturbations be included during training so that, when perturbations occur, servers will be more aware of how to re-adjust their kicking patterns most quickly at the next serve

AFFORDANCE AND ITS ROLE IN SEPAKTAKRAW KUDA AND SILA SERVE NON-PLANAR KICKING TECHNIQUES – A PRELIMINARY QUALITATIVE ANALYSIS FOR COACHING IMPLICATION

This study aimed to establish the affordance and its role in Sepaktakraw serve for coaching implications. Five successful kuda and sila trials performed by two trained male players, captured using a high-speed optical camera system, were analyzed. Variations in kicking limb hip-knee joint coordination to impact suggest ball placements be an affordance in Sepaktakraw serve. This affords what the server must do to ensure optimal foot-to-ball impact velocities without compromising ball velocities. With differences in kicking limb length, this coordination becomes player specific, and the ability to adapt and adjust his coordination pattern depends on such affordance. Servers must vary their movement pattern when executing the kuda or sila serve kicking by manipulating the knee-hip joint coordination with what the affordance affords the servers to do as it swings to impact

Association of maternal sleep practices with pre‐eclampsia, low birth weight, and stillbirth among Ghanaian women

ObjectiveTo assess sleep practices, and investigate their relationship with maternal and fetal outcomes, among pregnant Ghanaian women.MethodsIn a cross‐sectional study conducted at Korle Bu Teaching Hospital, Accra, Ghana, between June and July 2011, postpartum women were interviewed within 48 hours of delivery about sleep quality and practices during pregnancy. Interviews were coupled with a systematic review of participants’ medical charts for key outcomes including maternal hypertension, pre‐eclampsia, premature delivery, low birth weight, and stillbirth.ResultsMost women reported poor sleep quality during pregnancy. Snoring during pregnancy was independently associated with pre‐eclampsia (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.4–8.5; P = 0.007). The newborns of women who reported supine sleep during pregnancy were at increased risk of low birth weight (OR, 5.0; 95% CI, 1.2–20.2; P = 0.025) and stillbirth (OR, 8.0; 95% CI, 1.5–43.2; P = 0.016). Low birth weight was found to mediate the relationship between supine sleep and stillbirth.ConclusionThe present findings in an African population demonstrate that maternal sleep, a modifiable risk factor, has a significant role in pre‐eclampsia, low birth weight, and subsequently stillbirth.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135150/1/ijgo261.pd

Adverse events following immunisation (AEFI) of COVISHIELD vaccination among healthcare workers in Ghana

Objective To describe the incidence of adverse events following immunisation (AEFI) and determine the factors that affect the onset and duration of AEFI after COVISHIELD vaccination among healthcare workers.Design Prospective cohort study.Setting Tertiary healthcare, Korle-Bu, Ghana.Participant Three thousand and twenty-two healthcare workers at least 18 years of age were followed up for 2 months after receiving two doses of the COVISHIELD vaccine.Primary outcome The occurrence of the AEFI was identified by self-reporting to the AEFI team members.Results A total of 3022 healthcare workers had at least one AEFI (incidence rate of 706.0 (95% CI 676.8 to 736.1) per 1000 doses) with an incidence rate of 703.0 (95% CI 673.0 to 732.0) per 1000 doses for non-serious AEFI and an incidence rate of 3.3 (95% CI 1.6 to 6.1) per 1000 doses for serious AEFI. The most commonly reported systemic adverse events were headache (48.6%), fever (28.5%), weakness (18.4%) and body pains (17.9%). The estimated median time to onset of the AEFI following the first-dose vaccination was 19 hours and the median AEFI duration was 40 hours or 2 days. Delayed-onset AEFI occurred in 0.3% after first dose and 0.1% after second dose. Age, sex, previous SARS-CoV-2 infection, history of allergies and comorbidity were not significantly associated with the onset and duration of AEFI. However, participants who used paracetamol seemed to be significantly protected (HR 0.15; 95% CI 0.14, 0.17) from having a long duration of AEFI.Conclusion The results of our study indicate a high incidence of non-serious AEFI and the rare occurrence of serious AEFI after COVISHIELD vaccination in healthcare workers. The rate of AEFI was higher after the first dose than after the second dose. Sex, age, previous SARS-CoV-2 infection, allergies and comorbidity were not significantly associated with the onset and duration of AEFI

Cardiovascular disease prevention: Community Based Asset Mapping within religious networks in a rural Sub-Saharan African neighbourhood.

Prevalence of conditions which raise cardiovascular risk, such as hypertension and type 2 diabetes are seeing a dramatic rise in Sub Saharan Africa. A large proportion of these cases remain undiagnosed and there is limited resource to provide patients with self-management support and education once diagnosed. This study aimed to identify and catalogue community-based assets for the purposes of developing and deploying a screening and education programme for cardiometabolic risk factors (diabetes and hypertension) within religious organisations in a local community in a rural Ghanaian context. We utilised a community-based form of participatory research made up of a number of different components including community-based asset mapping and stakeholder consultation, supplemented by 18 in-depth interviews and 10 focus groups with n = 115 service users, to map existing assets with relevance to cardiometabolic health in this setting and context. Thematic analysis of interview and focus group data was performed to identify themes related to successful implementation of health screening. Two stakeholder workshops with local healthcare professionals, faith leaders and health policy makers were delivered to co-produced a prioritised list of recommendations and 'asset map' to aid deployment of mass screening within faith organisations in this context. The findings of this research highlight a number of 'hidden' community assets and motivational mechanisms at an individual, community and institutional levels; these have informed a list of recommendations which have been co-developed with the stakeholder group and local community to support the development of effective screening strategies for cardiometabolic conditions within faith organisations in this context. We have identified key mechanisms and assets which would support a sustainable screening approach designed to engage an underserved community at high CVD risk to promote general community health and well-being
