Sporis,Goran; Dujic,Ivan; Trajkovic,Nebojsa; Milanovic,Zoran; Madic,Dejan.
Soccer players are usually selected based on their anthropometry characteristics rather than their performances. Therefore, the purpose of this cross-sectional study was to examine the relationship between morphological and match performances among junior soccer players. Thirty seven junior soccer players were randomly selected using as stratification criteria age and playing role. Skinfolds (mm) were measured at six sites: triceps skinfold thickness, subscapular skinfold thickness, thigh skinfold thickness, calf skinfold thickness, supraspinal skinfold thickness and abdominal skinfold thickness. In addition, total distance covered during the match, as well as the distance traveled by walking, jogging, moderate and high intensity running and sprinting was...

Ergonomic evaluation of cashew nut shelling machine CIGR Journal
OYELAKIN, OLATUNJI OBAFEMI.
This paper presents the ergonomic evaluation of a manually operated village-level cashew nut shelling machine. A manually operated cashew nut cracking machine was evaluated. Fifty subjects took part in the study, with physiological, postural, and subjective measurements being taken. Comfort Questionnaire for cashew nut cracking machine (CQC) was also evaluated. Using the machine resulted in postural discomfort. The perception of the subjects as per the efficiency of the machine was neutral; 50% accepted that the machine is efficient, while the other 50% were unsatisfied. Following a participatory ergonomic process and using appropriate anthropometric measurements, an improved, adjustable prototype was developed. The lever arm was designed based on 5th...
