Aim. To develop novel strategies of patients selection and risk stratification after coronary artery bypass surgery before starting aerobic cardiorespiratory training programs.
Material and methods. ...One hundred thirty seven patients 4 weeks after coronary artery bypass surgery were included in our study. RARE scale (risk of activity related events), ergospirometric test, FIT treadmill score and certain laboratory parameters like hemoglobin and alaninaminotransferase were used.
Results. Logical interdependence is revealed between certain indicators of cardiorespiratory capacity and risk of developing unfavorable events due to aerobic training activities. Comprehensive protocol is developed based on multifactorial regression analysis, which allows to differentiate patients into low and high class of readiness to physical activities, including aerobic cardiorespiratory training programs.
Conclusion. The protocol includes following variables METs, RARE scale, FIT treadmill score, left ventricular ejection fraction, hemoglobin and alaninaminotransferase levels. It is very userfriendly, easy, practical and efficient.

The survey involved 40 athletes (20 sports pairs of the Juvenaly category). Results: the use of the means of functional training of the experimental technique has improved the level of special physical readiness of athletes. Conclusion: the positive effect of the means of functional training in the components of speed, power and speed-strength training on the dynamics of the level of special physical readiness of athletes from acrobatic rock'n'roll.
Police officers must perform various tasks in unpredictable work environments and potentially volatile situations. This study aimed to determine if cardiovascular fitness, body composition, and ...physical activity levels could predict performance in a Midwest Police Department's Physical Readiness Assessment (PRA).
Researchers collected data from thirty incumbent police officers (33.9 ± 8.3 years, female = 5). Anthropometric data included height, body mass, body fat percentage (BF%), fat-free mass (FFM), and maximal hand grip strength. The police officers also completed a physical activity rating (PA-R) scale to estimate maximal oxygen consumption (
O
) and the International Physical Activity Questionnaire (IPAQ). Police officers then conducted their department's PRA. Stepwise linear regression analyses were used to determine the relationship between predictor variables and PRA performance. Pearson's product-moment correlations investigated relationships between anthropometric, physical fitness, and physical activity variables and PRA performance using SPSS (v.28). The significance level was set at
< 0.05.
Descriptive data for the sample includes BF%: 27.85 ± 7.57%, FFM: 65.73 ± 10.72 kg, hand grip strength: 55.51 ± 11.07 kg, weekday sedentary time (WST): 328 ± 28.26 min, weekend day sedentary time (WDST): 310 ± 28.92 min, daily moderate-to-vigorous physical activity (MVPA): 29.02 ± 39.41 min, PRA: 273.6 ± 51.4 s and estimated
O
: 43.26 ± 6.35 mL kg
min
. The stepwise regression analyses indicated that BF% was predictive of PRA time (
= 0.32,
< 0.01); estimated
O
predictive of PRA time (
= 0.45,
< 0.001). There were significant correlations between BF % and PRA time (
= 0.57,
< 0.001), PA-R and MVPA (
= 0.71,
< 0.001), %BF % and WDST (
= -0.606,
< 0.001), hand grip and FFM (
= 0.602,
< 0.001) and PA-R and PRA time (
= -0.36,
< 0.05).
The results of this exploratory study highlight that higher estimated
O
and lower BF% were the best predictors for faster PRA completion times, accounting for 45% and 32% of the variance, respectively. The findings of this study support the need for wellness and fitness initiatives in law enforcement agencies focused on increasing cardiovascular fitness and physical activity while decreasing BF% to ensure optimal performance in policing and overall health.
The purpose of the work is to develop model characteristics of physical development, physical and technical preparedness of players of 15 years of different playing roles. Material and methods. ...Participants. In the study, 47 football players took part in 15 years of the Sports School "Areal" in Kharkov. Methods. Analysis of scientific and methodological literature, determination of physical development indicators testing of physical and technical preparedness, methods of mathematical statistics. The course of the study. The results of physical development, physical and technical preparedness of football players for 15 years are fixed. Model characteristics of physical and technical preparedness of young football players are developed. Analyzed comparative characteristics of the physical and technical preparedness of players 15 years of different playing roles. Results. It is established, according to the indicators of the physical development of players, players of different playing roles practically do not differ from each other. It is shown that the goalkeepers have practically the lowest technical and physical readiness indicators practically in all test results, in contrast to the attackers, defenders and midfielders. It is recommended that the development of a program for the development of physical qualities for goalkeepers, as well as the development of a separate program for improving the technical preparedness for players of each playing role. Conclusions. It is fixed, significant differences in the level of physical and technical preparedness between field players and goalkeepers. It is established that the greatest differences between representatives of different playing roles in terms of juggling, holding the ball on the foot, accuracy and range of strikes. It was revealed, not the reliability of the difference between the indicators of physical and technical preparedness of attackers, defenders and midfielders, which indicates their universality, and, therefore, possible replacement of each other.

Abstract
Introduction
Active duty Navy women participate in biannual Physical Fitness Assessments (PFAs), which include height and weight measurements and a Physical Readiness Test (PRT). PFAs are ...waived during pregnancy and resume the cycle after 6 months following maternity leave. The purpose of this study was to compare changes in PFA results over time between women who had or did not have a live birth during the follow-up period, and identify characteristics of women with lower PFA results postpartum.
Materials and Methods
This longitudinal study included 14,142 active duty Navy women, aged 19–40 years, with PFA results during July 2011–June 2015. Multivariable logistic regression, Stuart-Maxwell tests, and mixed effects modeling were used to examine changes in PRT scores and body mass index over time between women with and without a live birth during follow-up. All data were analyzed in 2017. This study was approved by the institutional review boards at the Uniformed Services University Office of Research and the Naval Health Research Center, and informed consent was waived in accordance with 32 CFR § 219.116(d).
Results
Postpartum women had increased odds of PRT failures (AOR = 3.88, 95% CI: 1.44–10.40) and lower PRT scores (AOR = 1.47, 95% CI: 1.12–1.92) up to 2.5 years postpartum, versus women without a live birth. Being enlisted, obese/overweight prepregnancy, and younger were risk factors for suboptimal PFA outcomes. Mean core strength and cardiovascular endurance, but not upper body strength, scores were significantly lower in postpartum women at 1 year postpartum versus women without a live birth.
Conclusions
Our findings show that additional interventions may be needed to assist women in returning to prepregnancy fitness up to 1 year postpartum. Future studies should examine additional factors that may improve postpartum fitness in addition to enhancing maternity leave policies.
