Impact of Prescribed Exercise on Physical Activity Compensation in Young Adults

Use of accelerometers and inertial measurement units to quantify movement of tactical athletes: A systematic review

The dynamic work environments of tactical athletes are difficult to replicate in a laboratory. Accelerometers and inertial measurement units provide a way to characterize movement in the field. This systematic review identified how accelerometers and inertial measurement units are currently being used to quantify movement patterns of tactical athletes. Seven research and military databases were searched, producing 26,228 potential articles with 78 articles included in this review. The articles studied military personnel (73.1%), firefighters (19.2%), paramedics (3.8%), and law enforcement officers (3.8%). Accelerometers were the most used type of sensor, and physical activity was the primarily reported outcome variable. Seventy of the studies had fair or poor quality. Research on firefighters, emergency medical services, and law enforcement officers was limited. Future research should strive to make quantified movement data more accessible and user-friendly for non-research personnel, thereby prompting increased use in tactical athlete groups, especially first responder agencies.

CADETS' MOTIVATION FOR MOTOR ACTIVITY AS AN IMPORTANT FACTOR IN IMPROVING THEIR HEALTH

OBJECTIVE

Aim: To investigate cadets' motivational priorities for physical exercises and sports in the process of their training and the dynamics of their health indicators.

PATIENTS AND METHODS

Materials and methods: The research was conducted at the National Academy of Internal Affairs in 2018-2022. The research of motivational priorities involved 372 male cadets from the 1st to the 4th instructional years aged 17 to 22. Two groups were formed to investigate the state of cadets' health: group A (n = 39) included motivated cadets who were additionally engaged in sports, group B (n = 66) was represented by insufficiently motivated cadets who undertook training according to the traditional physical education program and did not additionally engage in physical exercises and sports.

RESULTS

Results: It was found that the motivational priorities of cadets for physical exercises and sports vary depending on the instructional year. Group A cadets showed a significantly better level of health than those from group B, by 2.98 points (p ≤ 0.001) during the 4th instructional year.

CONCLUSION

Conclusions: A high level of cadets' health formed in the process of physical exercises and sports during training will contribute to the mastering of the educational program and, in the future, will ensure the effectiveness of their service activities. Therefore, the formation of cadets' conscious motivation for motor activities during training in order to improve their health is an important task of higher educational institutions.

Exploring activity compensation amongst youth and adults: a systematic review

BACKGROUND

Globally, significant efforts have focused on increasing physical activity and reducing sedentary behaviour in youth and adults across a range of settings (e.g., schools, workplaces, community, and home). Despite this, interventions have had varied efficacy and typically have failed to sustain changes in behaviours over time. One explanation that has been put forth to explain the mixed success of interventions is activity compensation. However, little is known about activity compensation, including whether compensation occurs, and perceptions and potential mechanisms of activity compensation. Understanding activity compensation would assist in tailoring and targeting of potential intervention strategies. The primary aim of this review was to synthesise research that has investigated activity compensation in youth and adults. The secondary aim was to identify potential reasons for and/or awareness of compensatory changes that may have occurred.

METHODS

An electronic search of the EBSCOhost (via Academic Search Complete, CINAHL Complete, Education Source, Health Source: Nursing/Academic Edition, PsycINFO, SPORTdiscus with Full Text), MEDLINE Complete, Global Health, EMBASE, Scopus and Web of Science databases up to May 2021 was conducted. Quality assessment of included quantitative studies used a modified compensation-specific McMaster Quality Assessment Tool.

RESULTS

A total of 44 studies met the inclusion criteria (22 = adult populations; 22 = youth populations) and were classified as (1) quantitative (n = 31); (2) combination of quantitative and behavioural (n = 11); (3) behavioural only (n = 1); and (4) qualitative (n = 1). Of the 42 studies that included a quantitative component, 11 (26%) reported compensation occurred. Within the 13 studies examining specific behaviours, 35 behaviours were assessed, and evidence of compensation was inconsistent. Compensation mechanisms included fatigue, time constraints, lack of motivation, drive to be inactive, fear of overexertion, and autonomous motivation.

CONCLUSION

Little evidence of compensation was reported in the included quantitative studies; however, inconsistencies between studies makes comparisons difficult. There was considerable variability in the types of behaviours assessed in quantitative studies, and few studies examined potential compensatory mechanisms. Future research, using compensation specific study designs, methods, and analytic techniques, within different population sub-groups, should address these evidence gaps.
