| Abstract: | Background: Reduced vital capacity (VC) and forced vital capacity (FVC) are associated with lead (Pb) exposure.Aim: The objective of this study is to analyse the effects of Pb on FVC and the shuttle run performance.Subjects and methods: Data were available for 184 male and 189 female Polish schoolchildren aged 10–15?years. Regression analysis was performed of shuttle run performance (dependent) on Pb and FVC.Results: Shuttle run time increased by 1.75 (±?0.77) and 1.97 (±?0.77) seconds for each 10?µg/dL increase in Pb blood among males and females, respectively. Higher shuttle run times indicate poorer performance. Average unadjusted blood Pb level in the sample was 5.27?μg/dL (±?0.19 SE) and 3.82?μg/dL (±?0.10 SE), respectively. Path analysis was used to assess the association of Pb level with shuttle run time. Blood Pb had a significant negative effect on VC (B=??13.60?±?3.28 SE], p?B?=??13.08?±?3.27, p?B?=??0.04?±?0.007, p?B?=?1.59?±?0.75, p?B?=?1.49?±?0.73, p?Conclusions: Thus, Pb had direct and indirect effects that increased shuttle run time, i.e. negatively affected performance. |
