Abstract

Project paper (B.Sc.(Environmental & Occupational Health)) - Universiti Putra Malaysia, 2015 Introduction: Motorcyclist faced more ergonomic hazard that related to the human body especially to the lower back. Objective: The main objective of this study is to determine the effectiveness of lumbar support. 'The main issues were approached in ergonomics based on the supportive of back pain which include 1) the analysis of muscle activation and 2) the analysis of muscle fatigue. Methodology: One hundred and twenty motorcyclists have participated in this study. All motorcyclists should in good physical condition and do not have musculoskeletal disorder symptoms. The subjects have divided into two groups which are control group and experimental group. Each participant was asked to sit for 2 hours on motorcycle in two different sessions in controlled room environment. This study is carried out by electromyography (EMG) to evaluation of muscular strain for each participant in each session and Borg 'Scale questionnaire to identify the rating of discomfort at interval 15 minutes in every session. The statistical analysis will find out by paired t-test by identifying the relationship between back support, muscle activation and muscle fatigue. Result: There is significant (t= 6.81, p = <0.001) when using lumbar support in muscle activity evaluation because the protection of staining back muscle helps to avoid putting too much strain on the lumbar area. There is also significant in Borg' Scale questionnaire evaluation (t = 4.82. p= <0.001) because by using a lumbar support improved posture because it trained the body to seated and stand upright in good posture. Conclusion: The intervention (lumbar support) is engineering improvement that gives the effectiveness and relaxation riding for motorcyclist. There is a significant different between pre evaluation without an intervention and post evaluation without an intervention.
