Acute stress and strain due to backpack loading among primary school pupils.
(2011) Abrahams, Sumaya.; Ellapen, Terry Jeremy.; Van Heerden, H. J.
Schoolbag carriage represents a considerable daily occupational load for children (Negrini et al., 1999). Whittfield et al., (2001) and Puckree et al., (2004) have reported that the carriage of heavy schoolbags is a suspected aetiological factor of the daily physical stress of school pupils. Methods: One hundred and eighty-seven pupils voluntarily participated in a controlled, descriptive, epidemiological retrospective study. Subjects’ biographical, epidemiological, exercise history and lifestyle information was gathered by a self-report questionnaire (adapted from Puckree et al., 2004). Subjects’ body mass, stature and mass of their schoolbags were measured using a Detecto stadiometer scale. Digital images, electromyographical muscular activity and a posture profile assessments were captured in the frontal and sagittal planes whilst the pupils were in the loaded (carrying a schoolbag) and the unloaded phases (not carrying schoolbags). These images were analyzed using biomechanical software, Dartfish. The study being retrospective in nature recorded the prevalence of schoolbag carriage musculoskeletal pain over the last 12 months. Descriptive statistical tests such as mean, mode, frequency, percentages and inferential chi-square statistical test (set at a probability of 0.05) were employed to analyze the data. Results: The result indicated that 78.99% of the cohort experience musculoskeletal pain due to schoolbag carriage (p<0.0001). The most prevalent anatomical sites of pain were the shoulders (37.04%), neck (20.37%), lumbar (11.73%) and thorax (10.49%) (p<0.0001). The mean mass of the schoolbag carried by the cohort was 5.45kg which was approximately 11.5% of their body mass. The predisposing factors of the musculoskeletal pain were the methods employed to carry the schoolbag (single strap (20.21%) versus double straps (76.6%), altered posture due to excessive schoolbag mass together with a reduced craniovertebral angle (p<0.05). Discussion & Conclusion: The excessive schoolbag mass carried by the pupils placed strain on the immature vertebral column of these pupils thus causing postural deviations which induced musculoskeletal pain and discomfort.
The effects of exercise on the aged.
(2002) Ellapen, Terry Jeremy.; Coopoo, Yoganathan.; Ramiah, Pramila Devi.
This study aimed to document the effects of regular exercise and physical activity on the aged. Subjects (n=S8) over the age of sixty-five participated in the study. All subjects were patrons from various retirement centers of the DAFTA organization (Durban Association for the Aged). The subjects completed a PAR-Q and informed consent form, which allowed the eligible to participate in the study. A pre and post-test battery was administered to measure the following parameters; body mass, height, girth measurement, agility and dynamic balance, muscle strength and endurance, flexibility, co-ordination, dynamic grip strength and aerobic capacity. During the experimental period the subjects engaged in a structured intervention exercise programme of 30 weeks. The intervention programme composed of games, walking, stretching, flexibility and resistance training exercises aimed at improving the following fitness components; agility and dynamic balance, strength, flexibility, co-ordination and aerobic capacity. Inferential and differential statistical methods were employed in order to analyzethe data. The study indicated that regular exercise and physical activity positively impacted the senior citizens' functional capacity and improved their quality of life (p
