VO2max Capacity and Prediction Model Development for Construction Workers
Keywords:
physical capacity, construction workers, prediction model VO2max, age, BMI, WCAbstract
The physical capacity (VO2max) of construction workers is an important factor in their work performance and safety. This study aimed to investigate the effect of age, body mass index (BMI), and waist circumference (WC) on VO2max, and developed a prediction model for VO2max of Indonesian construction workers. The study involved 45 healthy male construction workers who have no history of illness that affect physical capacity. VO2max was measured using a treadmill with the Bruce protocol. Data on age, BMI, and WC were collected and analyzed using multiple regression analysis to develop the prediction model. The average VO2max of workers was 3.98 ± 1.18 l/min. Age, BMI, and WC were found to affect VO2max of Indonesian construction workers. Age had a negative correlation with VO2max, while BMI and WC had a positive correlation. The results suggest that VO2max of younger construction workers is higher than that of older workers. The prediction model developed in this study using WC as a predictor can be used to estimate VO2max in Indonesian construction workers. This finding may have important implications for the health and safety of construction workers, as well as for the design of effective training and intervention programs to improve their physical capacity.
