The Influence of Physical Training on The Flight Performance of Cadets

This research was conducted to investigate the effect of physical exercise on the flight performance of fixed-wing cadets at Indonesia Civil Pilot Academy in Banyuwangi. The research employed a quantitative methodology, utilizing data collection through a questionnaire. The questionnaire was distributed to the cadets selected as samples, specifically DIII PST 2, DIII PST 3, and DIII PST 4 cadets, with 43 participants. Based on the instrument test conducted using regression analysis with ANOVA, it was found that the regression model (H1) significantly explained the variation in the observed data, with a significant F-ratio of 33.153 and a very low p-value (<.001). The hypothesis test results revealed that the coefficient for the dependent variable, flight performance, was 0.728, with a standard error of 0.126. The standardized coefficient (standardized) for this variable was 0.669. The obtained t-value was 5.758. The research findings indicate a significant influence of the independent variable, "physical exercise", on the dependent variable, flight performance. Aviation training facilities can use the results of this study to develop policies that encourage the inclusion of hands-on training in the flight curriculum. By doing this, you can ensure cadets are in good enough physical shape to complete their flight training. This study's results may open the door for the creation of fresh hypotheses on the connection between physical preparation and flying performance. The results of this study may serve as the foundation for creating a novel conceptual framework in this area.

High Decibels as Causing Deconcentration and Hearing Damage in Pilots, Crew Members and Passengers Passengers: Experimental Study in the Brazilian Air Force

Hearing is one of the main senses for aeronautical activities and plays a key role in the intelligibility of communications between pilots. Noise is a factor that impairs good hearing and can lead to various health problems, as well as impairing the performance of aviation cadets when they perform multiple tasks during flight. It is important to educate airmen about how noise can negatively affect instructional flights and the conditions that expose them to too much of a drop in concentration during flights. The sound pressure levels to which cadet airmen are exposed during their training is an aggravating factor for their communication and safety. The aim of this study was to determine whether there is a relationship between noise and loss of concentration during instruction in the Neiva T-25 aircraft, with the aim of collecting and analyzing data in order to improve air mission instruction in terms of health and flight safety by highlighting the harmful nature of noise in the Second Air Instruction Squadron (2º EIA). A questionnaire with eight questions about the influence of noise on the performance of aerial mission practices was administered to a sample of 20 Cadet Aviators from the Second Squadron who were taking part in the aerial instruction course in the Neiva T-25. The results of the questionnaires showed the importance of raising awareness about the harmful effects of noise in military activity, as it is a matter of flight safety.

The changes of these indicators under the influence of Hand-to-Hand Combat classes in annual dynamics have been presented. Positive influence of Hand-to-Hand Combat classes on functional state of cadets has been established, which contributes to increase of the efficiency of their professional activities in future. At the end of the study, cadets of the experimental group had significantly better indicators of functional fitness than the cadets of the control group. The obtained results proved that the developed training program based on the application of Hand-to-Hand Combat is effective and proves expediency of its application in practice.

Professional and applied physical training as the main type of military professional activity of cadets

Abstract. The readiness of the Armed Forces to repel the armed aggression of the Russian Federation is determined by many factors, one of which is the training of personnel. The activities of all military specialists, including physical training specialists, are aimed at ensuring a high level of personnel training. This is due to the fact that the development of physical qualities, formation and improvement of military-applied skills and abilities of servicemen is the key to successful combat operations.
 Physical readiness is the physical condition of a serviceman characterized by appropriate bodily development, certain functional resources of the body and the required level of motor fitness, which ensures the successful performance of combat missions for the purpose.
 Automation, computerization of military equipment and changes in the methods of warfare have led to a decrease in the share of physical effort in its control and muscle work in the structure of professional combat activity of servicemen in general, and at the same time increased the level of neuropsychological stress and tension, expanded the range of adverse factors of military combat activity. The connection between physical fitness and combat activity of servicemen of some military specialties has become hidden and indirect.
 Reforming educational institutions in the Armed Forces of Ukraine requires addressing global issues of improvement and finding new ways to solve the problems of vocational training of military personnel. The effective performance of cadets in educational institutions largely depends on their professional and applied training.
 One of the main tasks of teaching cadets the techniques and methods of ensuring professional and personal safety in emergency circumstances and in extreme conditions is to improve their firearms skills, as well as to increase the level of resistance to physical activity in training and service activities.
 The most important components of the professional skills of cadets of educational institutions are physical, professional and applied physical, psychological and firearms training.
 They belong to the cycle of professional disciplines and are designed to promote readiness for armed defense of the law, to maintain the constant readiness of future defenders to resolutely and skillfully stop illegal acts using physical force, special means and firearms.

Updating the content of the special physical training of cadets of higher education institutions with specific training conditions during martial law

It has been established that the official activity of police officers places increased demands on the level of special physical fitness of personnel. It has been established that a graduate of a higher education institution with specific learning conditions must possess not only a complex of knowledge, practical skills and abilities, but also a formed motivation and psychological readiness for the proper performance of official tasks in extreme situations caused by the introduction of martial law.
 On the basis of a survey of inspectors on self-defense tactics and personal safety of training centers of the State Government of Ukraine (n=27), gaps in the physical fitness of law enforcement officers with up to one year of practical experience were determined, directions for improving the content of special physical training for cadets of higher education institutions with specific training conditions were considered during martial law, the role of general physical fitness of law enforcement officers is outlined. The need to develop a single thematic content of the educational discipline for all institutions of higher education that train police officers has been established; the introduction of practical tasks into the educational process, which involve modeling situations of official activity with the complex application of police coercive measures. Emphasis is placed on strengthening the role of general physical training through the cadet's performance of various physical exercises while in full equipment.
 We see prospects for further research in the development of a set of exercises that will contribute to the development of professional and applied physical qualities of law enforcement officers.

НЕКОТОРЫЕ ПРЕДЛОЖЕНИЯ ПОВЫШЕНИЯ НАГЛЯДНОСТИ ПРИ ИЗУЧЕНИИ КОНСТРУКЦИИ И ЛЕТНОЙ ЭКСПЛУАТАЦИИ АВИАЦИОННОЙ ТЕХНИКИ

This article discusses the issue of increasing the use of the visual aids of the educational process when studying aviation technology at a flight school. An analysis of the educational and methodological complex of the educational disciplines selected for the study was carried out. The contradictions between the increasing requirements for the training of an aviation specialist and the possibilities of its training in modern conditions are identified. The introduction of simulation dynamic 2D models into the training process of flight personnel is justified as a way of increasing the use of visual aids of educational material taught. A version of a computer program for creating 2D models is presented. Using the example of the author's developments, the advantage of simulating dynamic 2D models in studying the design and operation of aircraft and engine systems and assemblies is shown. An analysis of the results of the implementation of developed innovations to improve visual aids was carried out. An increase in the performance of cadets in theoretical training before flying the aircraft under study was recorded. The recommendations for the development of 2D models and their use in the learning process are also offered.

The Influence Of Understanding The Collision Regulations (COLREG) 1972 On Competence Of Navigation Supervision Tasks On Ships

This research examined the impact of understanding the 1972 Collision Regulations (COLREG) on navigational watch competence on ships. COLREG, established by the International Maritime Organization (IMO), provides essential guidelines to prevent sea accidents, which every crew member must know. Mastery of COLREG is crucial for cadets in Nautical programs, ensuring they perform effectively during Marine Practice and as future officers. This study utilized a quantitative approach, with structured research objectives, subjects, objects, samples, and data sources. Methodology spanned from data collection to analysis. Findings indicated significant direct correlations: understanding of COLREG with navigation watch duty competence (coefficient = 0.201, p < 0.05), application of COLREG rules (coefficient = 0.235, p < 0.05), situation analysis (coefficient = 0.154, p < 0.05), and taking appropriate actions (coefficient = 0.188, p < 0.05). Similarly, cadet performance showed significant correlations with understanding and applying COLREG rules, situation analysis, and taking appropriate actions, with coefficients ranging from 0.078 to 0.174 (all p < 0.05). Additionally, a strong link was found between cadet performance and navigation watch duty competence (coefficient = 0.458, p < 0.05). The results of the study showed that the competence of navigation surveillance tasks on board ships was closely related to the factors of understanding the 1972 colreg regulations. The findings demonstrate that seafarers with a strong grasp of COLREG can more effectively identify navigational priorities and make appropriate decisions and actions in emergency situations.

Fuzzy Comprehensive Evaluation of Pilot Cadets’ Flight Performance Based on G1 Method

In this paper, to better evaluate the flight performance of pilot cadets, a flight performance evaluation index system was constructed based on the task of the traffic pattern, the flight training manual, and interviews with instructors. The fuzzy comprehensive evaluation model established by the G1 method was used to evaluate the flight performance of pilot cadets. The flight data of 30 flight cadets were collected to verify the applicability of the fuzzy comprehensive evaluation model. The results showed that the index system established in this paper can meet the requirements of flight performance evaluation. In addition, the fuzzy comprehensive evaluation results were consistent with the evaluation results of experts. Therefore, the system is effective and feasible for the evaluation of pilot cadets’ flight performance through the fuzzy comprehensive evaluation model established by the index system and G1 method.

Hardiness, leadership style and gender as predictors of leader performance in military academy cadets.

The U.S. Military Academy at West Point is widely considered the premier leader development institution in the United States. Since first admitting women in 1976, few studies have examined factors that may influence female cadets to perform as leaders in this environment. The present study analyzed archival data collected during a unique longitudinal study of leader development conducted at West Point during the years 1993-2000, the Baseline Officer Leader Development Study (BOLDS). Personality hardiness, transformational and transactional leadership styles were evaluated as potential predictors of performance as leaders, according to supervisor ratings. Regression results showed that female cadets excel as leaders, outperforming male cadets as a group. Hardiness and transformational leadership style predicted leader performance for both male and female cadets. Additional analyses indicated it is the transformational leadership element of "charismatic" (or idealized influence) leadership that accounts for this finding. The transactional component "management by exception-active" also predicted leader performance, but for male cadets only. This study confirms that hardiness and charismatic leadership style are important for leadership performance of both male and female cadets. For male cadets, leader performance was also tied to actively identifying and addressing failures in subordinates. Leader development programs for both men and women may thus be enhanced by including programs to develop personality hardiness and transformational leadership qualities.

Self-confidence Predicts Cadet Performance In A Hand-to-hand Combatives Course

EFFECTS OF TWO 8-WEEK PHYSICAL TRAINING MODELS (TRADITIONAL AND SPECIFIC) ON IMPROVED MILITARY PHYSICAL PERFORMANCE

The aim of this study was to compare the effect of eight weeks of traditional physical training (TPT) and military-specific physical training (MSPT) on the physical and operational performance of infantry cadets of the Brazilian Air Force (BAF). This study consisted of 27 male cadets (22.8±1.6 years, 76.0±9.2 kg, 1.77±0.05 m) stratified according to initial levels of physical fitness and randomly allocated in TPT (n= 13) or MSPT (n= 14) groups. The TPT group performed the basic military physical training provided for the military and the MSPT group conducted specific operational training. The variables were analyzed through two evaluations at the beginning and end of the eight-week training protocol. Anthropometric evaluations, physical fitness, and military operational physical tests were performed. Internal training load was determined through session rating of perceived exertion. Two-way (group and time) analysis of variance was used to compare groups and periods of training. Bonferroni test was used as a post-hoc when necessary. The effect sizes were presented by partial eta squared (ηp²) and Cohen dz. No group and time interaction was found for any variable. Regarding the time effect, there was a decrease in both groups in the anthropometric variables. The variables that increased over time for both groups were push-up and sit-up repetitions in 1 min, aerobic power, and squat jump height, whereas time in the military operational physical test decreased. Regarding the internal training load, no interaction between the group and period was observed. Therefore, both TPT and MSPT groups were effective in improving the physical and operational performance of military personnel after eight weeks of training.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0036/a.php" alt="Hit counter" /></p>

Weekly cumulative extracurricular core training time predicts cadet physical performance: A descriptive epidemiological study

BackgroundCore training can enhance athletic performance by enhancing core strength and stability. To achieve this outcome, however, a tailored training program is required; the normal military training curriculum is inadequate. The connection between cumulative weekly extracurricular training time, cumulative weekly extracurricular core training time and cadet performance is unknown. MethodsThe association between cumulative weekly extracurricular training time, cumulative weekly extracurricular core training time and performance has been discovered using a descriptive epidemiological study methodology. Questionnaires were used to collect information on personal characteristics and weekly cumulative extracurricular (core) training time, as well as the results of the Chinese Army Physical Fitness Test (C-APFT), which included 100-m dash, 5000-m run, 3000-m armed training run, 400-m steeplechase, 800 m breaststroke, horizontal bar pull-ups, 2-min sit-ups, 2-min push-ups, and hand grenade throwing. This study recruited two hundred and twenty male cadets (aged 18 to 23 years, 19.68 ± 0.91) from a military medical university. Results(a) The correlation between cumulative weekly extracurricular training time and C-APFT score is significant. The 100-m dash, 5000-m run, 3000-m armed training run, 400-m steeplechase, and 2-min push-ups performed the best when participants exercised for 5 to 10 h per week. (b) The number of cadets scoring good or excellent on the C-APFT improves with cumulative weekly extracurricular core training time. The recommended amount of core training for cadets per week is 120 min. (c) The average cumulative weekly extracurricular core training time was a effective predictor of performance on the 400-m steeplechase (R2 = 0.470, F = 10.641, P＜0.01), horizontal bar pull-ups (R2 = 0.238, F = 68.191, P＜0.01), 2-min sit-ups (R2 = 0.280, F = 84.710, P＜0.01), 100-m run (R2 = 0.031, F = 6.920, P＜0.01), 3000-m armed training run (R2 = 0.025, F = 5.603, P＜0.05), 2-min push-ups (R2 = 0.019, F = 4.295, P＜0.05), and hand grenade tossing (R2 = 0.025, F = 5.603, P＜0.05). ConclusionsActive participation in extracurricular core training can improve cadets' C-APFT scores. An average cumulative weekly extracurricular training duration of 5–10 h showed the most progress, and more than 120 min per week was ideal for extracurricular core training. The amount of extracurricular time spent on core training exercises each week can be used as a predictor of the C-APFT.

The Effectiveness of Utilizing HRV Indices as a Predictor of ACFT Performance Outcomes.

The Army Combat Fitness Test (ACFT) is a performance assessment used by the U.S. Army to assess a cadet's strength, endurance, and agility with a series of six events to ensure that cadets are combat ready. Heart rate variability (HRV) is an instrument that measures cardiac autonomic modulation and has been incorporated to predict the performance of athletes in daily training and competition since acute bouts of exercise alter HRV variables. To assess the applicability of using HRV to predict ACFT score performance outcomes in cadets. Fifty army cadets (n = 36 male; n = 14 female; age = 20.60 ± 3.61 years; height = 173.34 ± 10.39 cm; body mass = 76.33 ± 14.68 kg; body fat percentage = 17.58 ± 5.26%) completed the ACFT and reported for HRV assessment. HRV assessment had the participant lay supine for 5 minutes, and traditional time and frequency domain variables were assessed. A Pearson's correlation and multiple linear regressions were run. HRV time and frequency domains were not significantly correlated in linear regression models except the stress index (SI) and the 2-mile run (2MR). The standing power throw and sprint drag carry were significantly correlated with traditional HRV variables. HRV was not a predictor of ACFT performance for individual events or overall ACFT. The SI presented predictive properties only for 2MR, with no other significant correlations between HRV variables with standing power throw and sprint drag carry. The SI ability to predict 2MR performance outcome via HRV is a promising tool to assess army cadet performance and recovery.

Testing a supervisor‐led extension of self‐reflection resilience training: A controlled trial randomized by platoon at the Royal Military College

AbstractThe study tested an extension of a promising adaptive self‐reflective approach to resilience training. The extension integrated resilience training content in routine workplace activities via supervisors. Participants were military cadets (N = 168), randomized by platoon into two conditions. The control condition received the original self‐reflective resilience training only (n = 85), and the intervention condition additionally received a supervisor‐led extension of this programme (n = 83). Participants completed assessments of depression and anxiety symptoms and perceived stress at four time points over five months. Cadet performance scores were also obtained. Findings indicated that participants receiving the supervisor‐led extension demonstrated better psychological outcomes earlier than cadets in the control condition. However, at Time 4 both interventions had equivalent levels of mental health outcomes and perceived stress. The supervisor‐led condition demonstrated better average performance than the control condition for the performance measure congruent to the workplace activity in which the extension was applied. Mechanisms for the effectiveness of the supervisor‐led extension were explored. Analysis suggested that perceived supervisor support for the individual mediated the intervention–psychological outcome relationship. This research demonstrates the effectiveness of a scalable resilience intervention and speaks to a role of supervisors in facilitating resilience via supportive interactions.

Индивидуально-психологические особенности курсантов, обучающихся по образовательной программе среднего профессионального образования, определяющие успешность их обучения в военно-учебном заведении

The article discusses how personal qualities of cadets on the programmes of secondary vocational military education correlate with training outcomes. The paper outlines the importance of training mid-level professionals (ensigns) for the Armed Forces of the Russian Federation. Research in psychology and pedagogy most commonly focuses on cadets on university degree programmes (future officers). However, there is a dearth of psychological studies exploring how personal qualities of cadets receiving secondary vocational education impact training in a military school. The purpose of the article is to identify differences in the quality of cognitive processes (attention, memory, thinking, imagination, etc.) between “successful” and “less successful” students of military schools. It also aims to reveal the relationship between personal qualities of cadets (behavioral regulation, communicative potential, moral normativity, personal adaptive potential) and the results of training. The analysis is based on the data obtained during the psychological examination of applicants as part of the professional psychological selection to a military educational institution. The analysis identified differences in the level of general intellectual development (namely, cognitive processes: attention, memory, thinking, imagination, etc.) and personal qualities (communicative abilities, moral normativity, etc.) of cadets. These were compared with the results of their training at the end of the first year of a secondary military vocational education programme. The article explains which scores (the results of training) determine academically “successful” and “less successful” cadets. The success of training is assessed by the two following criteria: progress in academic disciplines; achievements in military service, sports, R&D, amateur art work, etc. This allows to identify exactly which individual psychological qualities have a higher impact on the effectiveness of academic performance and other activities of cadets during their studies. As a result, statistically significant differences between “successful” and “less successful” cadets were revealed in their level of memory, thinking, imagination, communication skills, moral normativity, and ability to adapt. The article provides recommendations for experts in professional psychological selection, teachers, commanders and psychologists on taking into account personal qualities of cadets during the selection and training of cadets at a military education institution.

The Effectiveness of STEM for Sea Project to Improve Cadets’ Performance as Preparation for Onboard Training

305 Subjective sleep predicts Cadet performance during U.S. Army Reserve Officer Training Corps Advanced Camp

Abstract Introduction U.S. Army Reserve Officer Training Corps (ROTC) Advanced Camp (AC) is a 29-day training that assesses military skills and leadership potential in college students training to become Commissioned Officers (i.e. Cadets). Military trainings are widely known to disrupt normative sleep. Additionally, operational sleep disruption is linked to performance decrements. This study examined the ability for objective and subjective sleep during ROTC AC to predict Cadet performance. Methods One hundred and fifty-nine ROTC Cadets (age 22.06±2.49 years; 76.1% male) wore an actiwatch device continuously for 29 days during AC. Paper surveys administered at the end of AC captured subjective sleep metrics during the training. ROTC instructors evaluated Cadet performance and provided scores of overall class rank and summary performance. Multiple and ordinal linear regressions assessed the predicative utility of subjective (sleep duration [SD]; Global score [Global] from the Pittsburgh Sleep Quality Index) and objective (Total Sleep Time [TST]; Sleep Efficiency [SE]; Sleep Latency Onset [SOL]; Wake After Sleep Onset [WASO] from actigraphy) sleep on performance. Results The interaction of SD and Global, when controlling for age and gender, significantly predicted increased Cadet rank, F(4,153) = 3.09, p = 0.018. Models testing the prediction of SD and Global on summary performance score were non-significant. Further, regressing of both Cadet rank and summary performance individually on objective sleep metrics, when controlling for age and gender, resulted in non-significant findings. Conclusion Subjective and objective sleep showed no significant individual predictive utility on performance. However, the combined subjective model significantly predicted that Cadets who slept worse (lower SD; higher Global) during AC received a lower rank at the end of the training. These findings suggest there may be a unique combined predictive utility of subjective sleep on performance when compared to the predictive power of individual variables. Therefore, subjective sleep may be better for predicting operational performance than objective sleep. Future analyses will refine these models and examine how performance on individual AC events may be influenced by sleep. Support for this study came from the Military Operational Medicine Research Program (MOMRP) of the United States Army Medical Research and Development Command (USAMRDC). Support (if any):
