“…These structural changes, together with physical (increasing height and change in body composition) and hormonal changes (females secrete more estrogen and males more testosterone) [ 13 , 19 , 22 ] lead to an increase in height and muscle mass in boys and an increase in body fat in girls during the onset of puberty [ 23 , 24 , 25 ]. Weight gain during puberty in girls has been associated with the increased accumulation of fat mass, possibly related to low motor skills and low participation in physical activities [ 15 , 17 ].…”

Puberty is a vulnerable period for musculoskeletal disorders due to the existence of a wide inter-individual variation in growth and development. The main objective of the present study was to describe the prevalence of back pain (BP) in the past year and month in school-aged children according to sex, age, maturity status, body mass index (BMI) and pain characteristics. This study involved 513 students aged between 9 and 16 years. Anthropometric measures were recorded to calculate the maturity stage of the students using a regression equation comprising measures for age, body mass, body height, sitting height and leg length. An ad hoc questionnaire composed of eight questions was used to describe BP prevalence in school-aged children. The results showed that the prevalence of BP in school-aged children was observed in 35.1% over the last year (45% boys and 55% girls), and 17.3% (40.4% boys and 59.6% girls, with an association found between female sex and BP) in the last month. The prevalence of back pain in the past year and month was higher the older the students were, or the more pubertal development they had experienced. The prevalence of BP in the last year was also higher in those with overweight or obesity. After adjustment for sex, there was an association between BP and older age and higher BMI in boys and an association between BP and higher pubertal development in girls. In summary, the present study showed that the prevalence of BP was related to the maturity stage and weight of the participants, with different prevalence patterns found according to sex.

Objective Core muscle dysfunction might serve as a risk factor for future musculoskeletal dysfunctions considering the high percentages of adults employed in mainly sedentary occupations in Iran, there is a need to clarify the strength of evidence on the potentially deleterious impact of prolonged sitting at work on the biomechanics of core/trunk muscles. This study aims to evaluate trunk/core muscle endurance in employees of seated and non-seated jobs in Shiraz University of Medical Sciences. Method A total number of 100 employees of Shiraz University of Medical Sciences (SUMS) were studied in 2 groups, seated jobs (n=50) and non-seated jobs (n=50). Seated jobs (office employees) defined as the jobs’ nature requiring the employees to sit more than half of their work time in a day, whereas non-seated jobs were those requiring less than half a workday to sit. Trunk endurance time measured by the 4 different stabilization tests including McGill’s trunk flexor endurance test, Sorenson’s trunk extensor endurance test and right and left trunk lateral flexor endurance test (Side-Bridge test). Results Statistical analysis was performed using the SPSS software version 21 (SPSS, Chicago, IL) Independent t test was used individuals in non-seated group had a statistically significant higher trunk endurance time for all 4 static tests (all P-values<0.001). Conclusion Prolonged occupational sitting is associated with reduced core muscle endurance. It may cause relationship between weakened core/trunk muscles and development of specific occupational musculoskeletal dysfunctions such as low back pain.

“…McGill test are used extensively in clinical practice and research to measure core muscle endurance (59)(60)(61)(62)(63). The flexor muscle endurance test engages the transverse abdominal muscles, the internal and external oblique muscles, and the rectus abdominis muscles (64).…”

Background. Musculoskeletal dysfunction is one of the most important occupational health issues. Prolonged sitting may be a risk factor for low back pain (LBP) associated with reduced muscle endurance, although many people with a sedentary lifestyle and sitting-type job report no pain and discomfort in the lumbar region. In the present study, endurance of the core muscles in individuals with sedentary jobs with nonspecific chronic LBP were compared with those without LBP. Objective. The present study compared core muscle endurance in individuals with sedentary jobs with and without nonspecific chronic low back pain. Methods. A total of 50 sedentary staffs were selected and divided into LBP and control group. Trunk muscle endurance was measured in seconds using the McGill's trunk flexor endurance test, the Sorenson's trunk extensor endurance test, and the right and left trunk flexor endurance test (Side-bridge test). Differences between the two groups were analyzed using multivariate general linear models in 2 ways ANOVA. Results. There were no significant between-group differences in the raw endurance of the extensor, flexor, right/ left flexor muscles (P ≥ 0.05). However, there were significant betweengroup differences in some self-reported physical fitness subscales (P < 0.05), duration of sitting at home (P = 0.035), frequency of assuming a slump sitting position (P = 0.049), and sitting with leaning back to the backrest (P = 0.02) at work. We developed uni-and multivariate general linear models, which showed adjustments to these parameters and unmasked fundamental between-group differences in extensor muscle endurance. Conclusions. Our finding does not support the popular opinion that daily sitting-while-at-work for long durations is necessarily associated with LBP. Instead, sitting posture, lower physical fitness levels, and shorter duration of sitting activities at home may be associated with reduced extensor muscle endurance in nonspecific chronic low back pain.
