Suenaga 25) , for the purpose of assessing the pattern of physical activity more precisely, further revised the usual Japan Government 4-point classification, into 6 groups: 1) sedentary, 2) sedentary and walking, 3) sedentary and brisk walking, 4) sedentary and exercise, 5) active with no regular job but spending spare time actively and, 6) active with no regular job but spending spare time actively with exercise. In the study of Suenaga 25) , all groups showed significantly higher values of V O 2 max than the sedentary group.…”

Work Form Affects Maximum Oxygen Uptake for One Year in Workers

et al. 2011

Our previous study suggested that the work form is related to the maximum oxygen uptake (VO 2 max). Therefore, we test the hypothesis by a longitudinal study that, besides these lifestyle-related factors, the work form increases VO 2 max among workers. Seven hundred and ninety nine males aged 37.1 ± 10.6 and 395 females aged 37.7 ± 10.5 (range: 20 to 59 yr old), who participated in The Total Health Promotion Plan (THP) at their respective workplaces twice in one year from 1997 to 1998, were selected. Data on VO 2 max were analyzed for age, systolic blood pressure (SBP), body mass index (BMI), work form (sedentary, standing, and ambulatory), exercise, and smoking. Age and the baseline variables for BMI and for VO 2 max showed significant negative relationships with a change in V O 2 max in males and females. Further, a change in the BMI showed a significant negative relationship with a change of VO 2 max in males. However, exercise habit and an ambulatory work form showed significant positive relationships with a change of V O 2 max in males. It was suggested that after adjusting for other factors in males, an ambulatory work form may be associated with an increase in VO 2 max in one year.

“…Suenaga 27) reported that, five years or more after stopping an exercise habit, there was significant negative partial regression coefficient between V · O 2 max and years stopped exercising. We found no significant relation between V · O 2 max and exercise history by simple correlation analysis, therefore it was not adopted as an independent variable for multiple regression analysis.…”

Physical Work Load Affects the Maximum Oxygen Uptake

et al. 2006

IntroductionAs a consequence of the WHO Ottawa Charter of 1986, Industrial Safety and Health Law was revised in Japan in 1988. It prescribes that execution of health promotion measures for workers is an obligation of employers. In line with this, Total Health Promotion Plan (THP) has been instituted 1) . THP includes not only medical examination, but also investigation of life-style, and assessment of physical fitness. Determination of the maximal oxygen uptake (V · O 2 max) as an indication of a whole body endurance is included in physical fitness assessment. Based on these results, guidance for health care and psychological counseling are provided to employees. It is reported that V · O 2 max is influenced by life-style, such as exercise and smoking 2-9, 30, 32, 33) . Moreover, the preceding researches reported that the fall in V · O 2 max is closely connected with cardiovascular system disorders, such as heart diseases, and hypertension 7,[10][11][12][13][14][15][31][32] . Based on this evidence and from a viewpoint of preventive medicine, V · O 2 max is being used as a health index in THP.

Distribution and determinants of maximal physical work capacity of Korean male metal workers

2007

The distribution of maximal physical work capacity (MPWC) can be used to establish an upper limit for energy expenditure during work (EEwork). If physically demanding work has wearing effects, there will be a negative relationship between MPWC and workload. This study was conducted to investigate the distribution of MPWC among Korean metal workers and to examine the relationship between workload and MPWC. MPWC was estimated with a bicycle ergometer using a submaximal test. Energy expenditure was estimated by measuring heart rates during work. The study subjects were 507 male employees from several metal industries in Korea. They had a lower absolute VO2max than the Caucasian populations described in previous studies. The older workers had a lower physical capacity and a greater overload at work. A negative relationship was found between MPWC and workload across all age groups. Upper limits for EEwork for all age groups and for older age groups are recommended based on the 5th percentile value of MPWC.
