However,relatively few systematic reviews of the scientific evidence for their health benefits, especially for older Chinese adults, have been undertaken.Evidence acquisition: Between January and March 2016, a systematic search was conducted using the CNKI and Pub Med databases to identify studies published between 2000 and 2015. Studies were selected for review if they were designed specifically to evaluate the health benefits of traditional Chinese sports and PAs in adults aged 50 years and older in the Mainland of China. The studies included observational, uncontrolled,and randomized and controlled designs. Papers published without an English title or abstract were excluded.Evidence synthesis: The initial search identified a total of 229 studies. After removing duplicates and studies that did not meet the inclusion/exclusion criteria, 95 studies were selected for review. Special attention was given to studies of the most commonly practiced activities: Tai Ji Quan,Qigong, and Yangko exercises. A positive association between these types of exercise and health benefits was noted for healthy older adults and those with chronic diseases. Evidence on other types of activities was less clear due to the limited number of studies conducted.Conclusion: There is promising evidence that traditional Chinese sports and PAs provide many health benefits for older Chinese adults. While additional scientifically rigorous research is warranted, promoting these traditional and culturally-based sports and PAs as forms of behavioral medicine in primary and secondary prevention of diseases among the aging Chinese population will help fulfill an urgent public health need.展开更多

It is related to the boxing practice-derived systemic responses and adaptations. The first part of the review has dealt with kinanthropometric parameters, skeletal muscle recruitment and ergometry. The following and third part of the review is going to deal with dietary supplementation, weight control, recovery, altitude, faith, life expectancy, gender and childhood. Search engines and printed documents have helped gather the information that have been commented in the present and second part: responses and/or adaptations relating to 1) metabolism, 2) skeleton, 3) nervous system, 4) endocrine system, 5) cardiovascular system, 6) urinary tract and 7) pulmonary system. Detailed titles and subtitles of this part of the review are found at the end of the journal paper introduction. The main teachings from the present journal paper may be acquired through the consultation of the tables and figures that are positioned in the text, not forgetting the reminders and advice(s) that appear at the end of each of the seven parts of the journal paper (2.1.6., 2.2.2., 2.3.2., 2.4.2., 2.5.4, 2.6.4. and 2.7.3.).展开更多

It is associated with an increased risk of low birth weight and prematurity and can contribute to impaired cognitive development in early childhood, as well as to maternal mortality. The impact on the fetus is even greater if maternal anemia onset is at an early stage, or prior to pregnancy. Iron salts, such as sulfate or fumarate, are widely used in the treatment of gravidic anemia, but due to various gastrointestinal side effects, many pregnant women are not compliant with treatment. Sodium iron EDTA, on the other hand, is highly absorbable and bioavailable. The latter improves hematological values and appears to be free from the usual iron-related side effects, hence compliance with this supplementation. Objectives: To evaluate the evolution of hemoglobin levels after sodium iron EDTA supplementation at the university Clinics of Kinshasa, to determine the frequency of gravidic anemia, the dose-dependent benefit of sodium iron EDTA supplementation in pregnant women and to identify factors associated with insufficient hemoglobin gain after supplementation. Methods: This longitudinal cohort will take place in the gynecology department of the University Clinics of Kinshasa from September 2022 to August 2023 and will include at least 54 pregnant women with anemia. Conclusion: The study will enable us to better assess the benefits of sodium iron EDTA in improving hematological values, as well as its tolerability in pregnant women suffering from anemia during pregnancy in our environment.展开更多

The objectives of this cross-sectional exploratory study were to compare flexibility, muscular endurance, body composition, and simple reaction time between TKD-trained adolescents and controls. Twenty TKD-trained adolescents aged between 10 and 14 and 20 age-matched healthy controls were asked to perform five physical fitness tests: a sit-and-reach test, leg split test, skinfold measurement, one-minute curl-up test, and ruler-drop reaction time test. The results revealed no significance differences between the two groups in sit-and-reach distance (p = 0.690), leg split angle (p = 0.789), percentage of body fat (p = 0.342), or number of repetitions in the one-minute curl-up test (p = 0.250). However, the TKD group had significantly faster reaction times in the rulerdrop test than the control group (p = 0.005). The results thus suggest that although TKD training may improve reaction times in adolescents, it may have little effect on flexibility, muscular endurance, and body composition (percentage of fat). TKD may be a suitable exercise for improving simple reaction time, but it may not be suitable for improving general physical fitness in adolescents.展开更多

This contribution challenges that narrative for overlooking, or being ignorant of, the way that societies around the world have approached the matter of the captured enemy fighter. Traces of some of the critical principles about humane treatment that we see in our present law can actually be found in much older societies from outside of Europe. A more accurate and representative way of understanding humanitarianism in the treatment of captured enemy fighters can and must be crafted, with the prevailing Euro-centric account balanced with practices, cultures and faiths from elsewhere. The quest to achieve more humane treatment in armed conflict is first and foremost a battle of the intellect. Narratives and conceptualisations that are more inclusive, recognising and appreciating of the ways of the rest of the world are likely to be more effective in communicating humanitarian ideals. This work adopts a new method of approaching the richness and diversity of the treatment of captured enemy fighters over time and space. This new framework of analysis uses six cross-cutting themes to facilitate a broader international and comparative perspective, and develop a more sophisticated level of understanding. The first theme is how older and indigenous societies approached the matter of captured enemy fighters. The second focuses on religions of the world, and what they teach or require. The third section examines the matter of martial practices and codes of ethics for combatants in certain societies. The fourth category engages with colonisation and decolonisation, and regulation （or non-regulation） of the treatment of captives of war. Fifth is the issue of modernisation and the impact it has had on armed forces and fighters, including on the treatment of captives. The final issu展开更多

All alone, the test proposal, which utilizes rapid repetitions of one judo technique off-balancing and body positioning by the same practitioner (Uchi-komi) may be usable instead of three non-judo specific tests: the vertical jump test of Sargent (1921), the multistage fitness test of Léger et al. (1984) and the Australian shuttle run test described by Cazorla et al. (2004). However, the judo specific test proposal 1) specificity is still to be increased and must ideally turn into test individualization (using the proposal as a template), as in judo, trained individuals have favorite techniques they use in preference to others;2) represents competing judo practitioners efforts quantitatively but not qualitatively (throws are represented, but neither hold downs, arm-locks, strangle holds nor chokeholds);3) brings subjects to physiological exhaustion but psychological exhaustion emotional component is left out of account. Uchi-komi utilized by the test proposal could better be replaced by continual completions of variable judo techniques by the same practitioner (Kakari-geiko) which allow the practitioner who is attacking by means of judo techniques (Tori) to utilize linked up techniques. Nevertheless, to date, the test proposed for assessing the suitability of judo practitioners to meet competition demands is the most judo specific and the most economic.展开更多
