“…[9] Children between the age group of 13-16 years are of great concern as junior students in secondary school have a critical spinal development stage. [3] Osgood-Schlatter syndromeone of the most common orthopedic diseases can be related by heavy loading on the patellar tendon leading to tendinopathy. Adding load can further worsen the condition for these school going children.…”

Postural and physiological changes are the distinct changes occurring in the adolescence which contributes fitness level of a child. The biomechanics of these children are highly affected by load carriage while climbing stairs which results in increase in cardio respiratory responses. Evaluation of the cardio respiratory changes is necessary in curbing further damage. In the study we evaluated the effect of backpack load influencing the cardio respiratory measures in stair climbing adolescents. 100 adolescents subjects aged 13-16 yrs were selected for the study, with graded loading for three consecutive days. Heart rate, rate of perceived exertion and respiratory rate were measured pre and post loading. Values of all the parameters on each day were compared. With increase in load, increase in heart rate, rate of perceived exertion and respiratory rate were significant when compared with progression in load. Although the measure which is highly affected amongst these was heart rate. The backpack with 30% load produces the elevation of variables at a greater extent hence there should be curbing of weight of 30% of adolescent’s body weight. Key words: Adolescence, Backpack load, Rate of Perceived Exertion.

“…Finally, they concluded that females should carry load less than 10% of BW, whereas, men can carry up to 15% static load of BW for the time period of 15 minutes. [2] reported the relation between musculoskeletal pains or discomforts associated with heavily loaded school bags. A treadmill test was conducted on 105 students walking with different loads such as right side, left side, and back loads, respectively.…”

Ergonomics is defined as the study of people's efficiency in their working environment. This scientific discipline is concerned with understanding the interactions among humans and professions that apply theories, principles, data, and methods to design in order to optimize the human well-being and overall system performance. This discipline comprises of three main fields of research such as; cognitive, organizational, and physical ergonomics. The Journal of Ergonomics is an open access journal that aims to publish complete and reliable sources of the information. The present issue of Volume 6 Issue 5 published 3-Research articles, 2-Editorials, and 1-Commentry paper.

BACKGROUND: Unsuitable schoolbags may stress the spine and promote poor body posture, particularly for school students. Global recommendations have suggested that schoolbag weight must not exceed 10% of a healthy student’s body mass, which would need continuous monitoring and enforcement. OBJECTIVES: The present study presents a comparison between an ergonomically designed schoolbag, which helps reduce the potential effects of carrying a load, and a commercial one. METHODS: A total of 30 healthy male students were recruited for this experiment. Independent variables determined were schoolbag type (ergonomically designed and commercial schoolbags) and three load levels based on body mass percentage (i.e., 10%, 15%, and 20% of body mass). Heart rate variability (HRV) and body discomfort rating were then measured. RESULTS: Our results showed that the developed schoolbag promoted enhanced subjective measures and HRV response at 15% and 20% of body mass. Participants who wore the developed schoolbags experienced significantly lesser neck, shoulder, upper and lower trunk discomfort than those who wore the traditional ones. Changing the load percentage from 10% to 15% caused an increase in heart rate among participants carrying a commercial schoolbag but a decrease in heart rate among those carrying the developed schoolbag. CONCLUSIONS: The findings presented herein suggest introducing strategies for reducing the potential impact of load carrying through the combined effect of new educational inventions and policy changes.
