It is a highly contagious disease, which elicits high levels of fear amongst the world population and is considered a threat to the world economy. As a response to this pandemic, international governments have devised unconventional measures to guard the health of their citizenry. Among these are the “new normal” country lockdown that mandates working from home, home-schooling of children, and physical/social distancing from friends and family. For the majority, this has resulted in momentary job loss and loneliness, and other psychological illnesses. Hence millions are frightened, depressed and panic easily as a result of the tension due to the uncertainty, which interferes with their job performance, livelihoods, international trade and the world economy. If not mitigated, this is likely to cause physical health deterioration, with severe mental illness being the outcome. To reduce mental health illnesses during and after the COVID-19 pandemic, evidence suggests prioritising regular participation in physical activity and exercise across lifespan. It is also important for medical experts who specialise in the care and management of mental health to recognise physical activity and exercise as a medicine that can ameliorate some mental illnesses and their associated risk factors. © 2021 Onagbiye et al.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":"14 1","pages":"30-33"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46454601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physical training is one of the main subjects of professional training and an important means of psychophysical readiness formation of servicemen of various military specialties for modern extreme professional and combat activities. The aim of the study is to examine the efficiency of the experimental academic program of the discipline of Physical Education, and Special Physical Training concerning the formation of psychophysical readiness of cadets of technical higher military educational institutions for future professional and combat activity. The study was conducted at S. P. Koroliov Zhytomyr Military Institute. 120 male cadets participated in the experiment. An experimental group (EG), which consisted of the cadets who were studying according to the experimental working academic program of the discipline (n=60), and a control group (CG), which included the cadets studying according to the current working academic program of the discipline (n=60) were formed. The criteria of the efficiency of the experimental program are determined to be the indicators of general and special physical fitness of cadets and the level of professionally important psychological qualities. Research methods: theoretical analysis and generalization of scientific and methodical literature, pedagogical observation, pedagogical experiment, methods of mathematical statistics. It was discovered that conducting classes according to the experimental program contributed to the improvement of the level of development of the cadets’ special physical qualities, mastering military-applied skills, the formation of professionally important psychological qualities. The most significant changes in EG cadets occurred in overcoming obstacle course, holding the angle on parallel bars, holding the body in a horizontal position, tests for determination of attention distribution and volume, mental performance – at the end of the experiment, and the indicators of EG cadets were significantly (p˂0.05-0.001) better than those of CG.It proves the necessity of correcting the academic program of Physical Education and Special Physical Training for senior cadets with the aim of their psychophysical readiness formation for future professional and combat activity.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":"14 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41925824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
