AB  - Purpose – The purpose of the study is to determine the prevalence of stress and to identify the occupational
stressors among Lebanese police officers.
Design/methodology/approach – Operational Police Stress Questionnaire (PSQ-op) was addressed to 100
randomly selected male Lebanese Police officers. Twenty items from the PSQ-op were run through the principal
component analysis to determine the most significant factors of stress and loading within each of the factors.
Findings – The results indicated that 59% of officers reported moderate stress level and 41% reported
strenuous stress. Principal component analysis identified six independent factors or stress among Lebanese
police officers explaining in total 72.1% of the total variance: excessive workload (30.6%), social-life time
management (12.8%), occupational fitness (9.1%), success-related stress (8.6%), physical and psychological
health (5.8%), and working alone at night (5.2%).
Research limitations/implications – This research approach encountered some limitations so further
research must: use a larger sample size, include female gender and identify other sources of stressors mainly
organizational or job context stressors.
Originality/value – Addressing and understanding stress factors among Lebanese police officers helps
improving awareness and developing individualized treatment strategies leading police officers to engage in
stress-management training to learn coping strategies and use effective tools for preventing stress before it
becomes chronic.

AB  - The aim of the research is to determine the reliability of testing various contractile functions of a male hand based on motoric and functional dominance and age. The examinee takes a seat with their arm extended or mildly flexed in a mildly abducted position. For the measuring purposes, dynamometric probe with isometric straining conditions fixed to a special construction was used. The 'Isometrics' (ver. 3.1.1) was used and frequency of data selection was realized on the level of 500 Hz. The sample includes 269 male examinees aged from 14.0 to 69.9. The results of descriptive statistics have shown that in relation to the tested sample for the non-dominant hand, values for maximum force (Fmax) range from 462.8 to 529.0 N, for explosive force (RFDmax) the range is from 1621.6 to 1972.8 N/s and for muscular force impulse (ImpF50%max) from 8203.9 to 15552.3 Ns, while Fmax values the dominant hand ranges from 478.1 to 566.2 N, for RFDmax it ranges from 1742.6 to 2119.0 N/s and for ImpF50%max 9516.7 to 16845.1 Ns. The results have shown that it is reliable to measure all three examined contractile hand characteristics where by ICC ranges from 0.938 to 0.977 for Fmax, from 0.903 to 0.971 for RFDmaxand from 0.747 to 0.943 for ImpF50%max. The second try as the better result should be considered the representational value for Fmaxand RFDmaxvariables, regardless of the hand dominance or age group. While for the variable ImpF50%max, in the age groups from 35.0 to 49.9 and from 50.0 to 69.9, the first tested try for both hands should be considered, in 14.0 to 19.9 years group the second try should be taken into consideration, and in 20.0 to 34.9 age range, the better result of the non-dominant hand is the first try, and of the dominant is the second try.
AB  - Cilj istraživanja je da se utvrdi pouzdanost testiranja različitih kontraktilnih funkcija šake muškaraca, u zavisnosti od motoričko-funkcionalne dominantnosti i uzrasta. Ispitanik zauzima sedeći položaj sa opruženom ili blago fleksiranom rukom, postavljenom u blago abdukcioni položaj. Za potrebe merenja upotrebljena je dinamometrijska sonda, sa izometrijskim uslovima naprezanja, fiksirana za specijalnu konstrukciju. Korišćen je softver 'Isometrics' (ver. 3.1.1), a frekvencija odabira podataka realizovana je na nivou od 500 Hz. Uzorak je obuhvatio 269 ispitanika muškog pola, uzrasta od 14.0 do 69.9 godina. Rezultati deskriptivne statistike su pokazali da se u odnosu na testirani uzorak za nedominantnu ruku vrednosti ispoljene maksimalne jačine (Fmax) nalaze u rasponu od 462.8 do 529.0 N, za eksplozivnu jačinu (RFDmax) u rasponu od 1621.6 do 1972.8 N/s i za impuls mišićne jačine (ImpF50%max) od 8203.9 do 15552.3 Ns, dok su vrednosti Fmax za dominantnu ruku u rasponu od 478.1 do 566.2 N, za RFDmax u rasponu od 1742.6 do 2119.0 N/s i za ImpF50%max od 9516.7 do 16845.1 Ns. Utvrđeno je da se pouzdano mogu meriti sve tri ispitivane kontraktilne karakteristike šake, pri čemu se ICC nalazi u rasponu od 0.938 do 0.977 za Fmax, od 0.903 do 0.971 za RFDmax, i od 0.747 do 0.943 za ImpF50%max.Kao reprezentativnu vrednost za varijable Fmax i RFDmax, bez obzira na dominantnost ruke, ili uzrasnu grupu, treba uzimati drugi pokušaj kao bolji rezultat. Dok za varijablu ImpF50%max, u uzrasnim grupama od 35.0 do 49.9 i od 50.0 do 69.9 godina, uglavnom treba uzimati prvi testirani pokušaj za obe ruke, u grupi od 14.0 do 19.9 godina drugi testirani pokušaj, a u uzrastu od 20.0 do 34.9 godina bolji rezultat nedominantne ruke je prvi, a dominantne drugi pokušaj.

AB  - The increase in body mass at the expense of fat mass can lead to impaired health, professional-working and morphological status. The aim of this study was to define the descriptive indicators in measured morphological components and the establishment of standards for the initial values of their assessment. The sample of examinees included 144 female students of the Academy of Criminalistic and Police Studies (ACPS): Age - 19.7 ± 1.1 years; BH - 169.3 ± 5.3 cm, BM - 61.3 ± -6.9 kg, BMI - 21.2 ± 2 kg/m2. The measurements were performed at the Faculty of Sport and Physical Education, University of Belgrade, by standardized procedures with multichannel bioelectrical body composition analyzer 'InBody 720'. Variables for classification were: Body Weight (BW, kg), Body Height (TV, cm), Body Mass Index (BMI, kg/m2), Body Fat Mass (BFM, kg), Percent of Body Fat (PBF, %), Visceral Fat Area (VFA, cm2), Fat Control (FC, kg), Trunk Fat (TF, kg) and Trunk Fat Index (TF_BFM, %). Classes are defined by the characteristic seven subclasses: very poor, insufficient, below average, average, over, overly and unacceptable, in accordance with the sport metrology procedures. The results were statistically analyzed using descriptive statistics. Based on the obtained results, the examinees were distributed in the respective clusters. It was found that ACPS students have a distribution of results indicator of body fat shifted toward lower values , but it can be concluded that in general level the examinees belong to a population with normal values in relation to the criteria of the World Health Organization.
