Comparison of physical fitness outcomes of young South African military recruits following different physical training programs during basic military training
Physical training (PT) is an integral part of developing operational fitness. The objective of the study was to compare the physical fitness outcomes of two groups of young South African military recruits completing 12 weeks of Basic Military Training (BMT) who followed different PT programs. A historical control group (NCPG: female n=115, male n=73) that followed a traditional PT program and an experimental group (CPG: female n=85, male n=100) that followed a new cyclic-progressive PT program participated. The standardised PT test was taken at the beginning, the fifth week and the end of the BMT period. The changes in the fitness components evaluated by the South African National Defence Force (SANDF) standardised PT test were compared. Although the new cyclic-progressive PT program elicited more change (p<0.05) in the fitness parameters measured, it only yielded superior performance at the final measurement in the men’s push-ups (p=0.0001). This may be attributed to the relatively greater amount of upper body exercises performed by the CPG and by the additional resistance offered by pole PT. The new cyclic-progressive PT program has been mandated for all BMT units across the SANDF.http://academic.sun.ac.za/sajrsper/am201
Flexibility as risk factor for stress-fracture development in South African male soldiers
BACKGROUND : Stress fractures are a common military training injury. Flexibility of muscles and joints may directly influence
stress-fracture risk by way of altering the forces applied to bone. Hip external rotation and ankle plantar- and dorsiflexion have
been inconsistently reported to pose a risk to stress fracture development in military soldiers. Thus this study aimed to present
results that could help define the risk flexibility may pose in the development of stress fractures amongst military male soldiers.
METHODS : An experimental one-group pretest–posttest study design assessing the injury incidence, bilateral hip external
rotation, ankle plantar- and dorsiflexion of South African male military soldiers (n = 100) undergoing 12 weeks of basic military
training (BMT) was undertaken. The parametric t-test for dependent samples (α = 0.05) and effect size (ES) was used to analyse
the data.
RESULTS : No stress fractures were diagnosed in the 100 operational military training injuries reported. BMT resulted in significant
mean decreases of 10% (L) and 17% (R) in hip external rotation and 18% (L) and 14% (R) in ankle plantar flexion respectively,
whilst a significant increase of 37% (L) and 39% (R) dorsiflexion was observed.
CONCLUSIONS : Although normal ankle and limited hip external flexibility do not appear to predispose these male soldiers to stress
fracture development these variables should not be excluded as possible intrinsic risk factors.http://medpharm.tandfonline.com/loi/ojfp20am201
The effect of chronic low back pain on daily living and fear-avoidance beliefs in working adults
Low back pain (LBP) has become one of the most influential musculoskeletal diseases of modern
society. Exercise has been shown to be very effective in the treatment of chronic low back pain
(CLBP). The goal of the study was to test the effect of two exercise intervention programmes
(conservative and progressive-aggressive programmes) for 12 weeks on CLBP and their impact
on the activities of daily living, and fear avoidance beliefs about physical activities and workrelated
activities. In total 22 participants were recruited for the study and randomly assigned to
one of two exercise groups: 11 participants in the conservative exercise group and 11 in the
progressive-aggressive group). The Oswestry Disability Index (ODI), the Functional Rating
Index (FRI), and the Visual Analogue Scale (VAS) for pain measurement was completed by the
participants pre- and post-test. There were no statistically significant differences at the 5% level
between the conservative and progressive-aggressive programmes. In conclusion, the results
from the present study indicate that both types of programmes have shown to be very effective in
the improvement of daily living and fear avoidance beliefs. On the basis of the magnitude of
improvement, an aggressive-progressive exercise programme may be a little more effective than
a more conservative exercise programme.http://www.ajol.info/journal_index.php?jid=153&ab=ajpherd2017-03-31am201
Study protocol on advance care planning in multiple sclerosis (ConCure-SM): intervention construction and multicentre feasibility trial
Multiple sclerosis (MS) is the most common cause of progressive neurological disability in young adults. The use of advance care planning (ACP) for people with progressive MS (pwPMS) remains limited. The ConCure-SM project aims to assess the effectiveness of a structured ACP intervention for pwPMS. The intervention consists of a training programme on ACP for healthcare professionals caring for pwPMS, and a booklet to be used during the ACP conversation. Herein, we describe the first two project phases
A comparison between the cardio-stress indices of an active and a sedentary population
Die moderne leefwyse bring dikwels mee dat ons die belangrikheid van liggaamlike oefening uit die oog verloor. Ons toenemend passiewe leefwyse het gelei tot ’n aansienlike toename in die voorkoms van lewenstylsiektes soos hipertensie en verskeie vorme van vaskulêre
patologie. In hierdie studie word die kardiostres-indekse (KSI’e) van aktiewe en sedentêre individue met mekaar vergelyk ten einde insig te verkry in die uitwerking van die aansienlike veranderinge wat in die gemoderniseerde samelewing plaasgevind het. Die aktiewe populasie
het bestaan uit 217 weermagrekrute wat reeds 20 weke van hul basiese weermagopleiding voltooi het. Die (n = 126) lede van die sedentêre populasie is gewerf uit ’n tradisionele tersiêre onderwysinstansie. Die deelnemers uit beide populasies moes drie toetssessies bywoon
wat gedurende week 1, week 12 en week 20 gehou is. Hulle het ’n nie-ingrypende ViportTMtoets ondergaan om hul KSI, harttempo en QRS-duur te bepaal. Die resultate het getoon dat alhoewel die basislyn vir KSI, bloeddruk en harttempo aanvanklik hoër was onder die aktiewe
populasie, die aanvang van die liggaamsoefeningprogram ten opsigte van hierdie drie faktore ’n geleidelike afname en dus ’n verandering in die rigting, en uiteindelik gesonder marges tot gevolg gehad het. Die KSI het egter nie die normale reikwydte ten opsigte van een van die twee groepe bereik nie, wat daarop gedui het dat alhoewel liggaamlike aktiwiteit fisiologiese stresvlakke verminder, ander sleutelfaktore, te wete leefwyse en stresvlakke, ook in ag geneem moet word. Die studie onderskryf die idee dat ’n toename in liggaamlike aktiwiteit die potensiaal het om ’n individu se vatbaarheid vir kardiovaskulêre siektes te verminder. Die
studie ondersoek ook die uitwerking van oefening op die hart deur die gebruik van KSI as ’n meetinstrument.A comparison between the cardio-stress indices of an active and a sedentary population.
Our modern lifestyle often results in the importance of physical exercise being overlooked. The increasingly passive way of life has resulted in a notable increase in the prevalence of lifestyle disorders, such as hypertension and some forms of vascular pathology. This study compares the cardio-stress indices (CSIs) of active and sedentary individuals to provide insight into the impact of the significant changes that have taken place in the modernised society. The active
population consisted of 217 military recruits who had completed 20 weeks of basic military training. The sedentary population (n = 126) was sourced from a traditional tertiary institution where the focus is on attending lectures. Participants from both populations were required to
attend three testing sessions, which were held during Week 1, Week 12 and Week 20. Subjects underwent a non-invasive ViportTM test to measure their CSI, heart rate and QRS duration.
The results showed that although baseline readings for CSI, blood pressure (BP) and heart rate (HR) were initially higher among the active population, the commencement of the physical training programme resulted in a steady decline in respect of these three factors to approach
healthier margins. However, the CSI for neither population reached the normal range, indicating that although physical activity reduces physiological stress levels, other key factors, namely lifestyle stress levels, must also be taken into account.The study supports the notion
that increased physical activity has the potential to reduce the predisposition of an individual to cardiovascular disorders and contributes towards establishing the effect of training on heart health by using CSI as a means of measurementhttp://www.satnt.ac.zaay201
Postural variations in Cardio Stress Index scores
Numerous factors influence heart rate variability, including age, exercise and posture. The Cardio Stress Index (CSI) is a transformed measure of heart rate variability that is determined via a miniature digital multi-channel electrocardiogram system. Although the CSI and heart rate variability are reportedly analogous, little is known about how the two concepts compare in peer-reviewed research. The aim of this study was to examine the differences between CSI and heart rate as measured on a mini- electrocardiogram device when subjects were sitting upright and when they were lying down (in supine position). This is a case-series study with no intervention or follow-up. Sitting and supine CSI and heart rate readings were compared in a random sample of 55 women volunteers recruited through advertising in Pretoria, South Africa. The mean age of the sample was 25.01 years (SD = 7.56). After completing a biographical questionnaire, subjects’ CSI and heart rates were evaluated using a digital medical device, the ViportTM. The combined CSI for the group was elevated above the normative value of 20% (31.00%; SD = 14.03). The seated, supine and combined CSI all differed significantly from one another (p<0.05) and the CSI was significantly correlated with heart rate (p=0.41). In conclusion, the CSI readings, like heart rate variability measurements taken in different postures, cannot be used interchangeably in clinical practice or in research. The CSI appears to mirror existing research evidence on heart rate variability and posture.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher

Comparison of the performances of male and female armed services recruits undergoing sports vision testing
Research has shown that a strong correlation exists between vision and performance. In the sporting environment, it is believed that athletes perform better than non-athletes and males perform better than females. In this study we used sports vision to compare performance between males and females. One hundred and thirty male and one hundred female armed service recruits were tested, using techniques of visualization, eye-hand coordination, focusing, sequencing, tracking and reflexes. Previous research has shown that the difference in performance in both males and females is the result of brain lateralization, test familiarity and nerve conduction velocity in the brain. This was, however, not reflected in the study. Results showed a significant difference in performance with regard to visualization (p=0.006), tracking (p=0.048), reflexes (p=0.0001) and sequencing (p=0.046). The increased performance might become more evident with repetition of tests. Future research should therefore investigate the exact physiological mechanisms and interrelation of variables thought to affect performance.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher
Evaluation of visual skills in sedentary and active work environments
The two fundamental categories of vision include visual-perceptual and visual-motor skills. Visual-motor skills encompass three essential ocular motor skills, namely focusing, eye-hand coordination and tracking. The aspects of the visual perceptual process include visual memory and visualization. This study aims to determine whether there is a difference in the visual performance of individuals exposed to a sedentary work environment and those exposed to an active work environment. The participants consisted of military recruits, who underwent a 12 week intense training regimen, and second year university students, who were subjected to a battery of vision testing to determine their visual performance. It was hypothesized that training recruits will possess superior visual skills in comparison to university students. The results indicate that training recruits possess superior skills in eye-hand coordination and visualization, while students showed enhanced tracking and sequencing skills. Cardio stress indices and blood pressures were tested to determine the heart health of the subjects and whether these factors influence visual attributes. Although not significant, the results indicate a decrease in cardio stress index in training recruits although their blood pressures were higher than those of students. The results concur with previous studies, which have shown that individuals exposed to physical activity, even for a short period of time, tend to acquire superior visual skills. However, the skills are honed according to the field of expertise due to the transfer effect that occurs in the brain. The findings of the study support as well as contradict evidence regarding sports vision testing and training, thus further investigation is required to elucidate the controversy regarding vision testing.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher
Initial assessment of well-being in South African armed services personnel
As professionals in law enforcement and defence (armed services) function under high pressure, the maintenance of overall health should be emphasized and closely monitored in training facilities. The aim of this research was to assess current health status and risk factors of the members of three armed service training facilities. This represents the first step in an integrated approach toward health maintenance in this important sector. The sample consisted of 323 members from three different armed service training facilities in South Africa. The subjects completed a questionnaire on health history and coping with stress. Heart health, body composition, general fitness and co-ordination were then examined. The mean age of the sample was 38.08 years (SD=8.81). The mean blood pressure readings were pre-hypertensive (Systolic 127.4mmHg, SD=16.67; Diastolic 82.74mmHg, SD=10.94) and the mean BMI was in the overweight category (27.97kg/m2, SD=8.81). The percentage (more than 40 %) of subjects that require physical fitness intervention reflects an urgent need for effective implementation of wellness programmes in this sector.http://www.ajol.info/journal_index.php?jid=153&ab=ajpher
