The short-term effects of ambient black smoke concentrations on total non-accidental, cardiovascular and respiratory mortalities in Nis, during the 2000-2003 period, were investigated. Daily measurements for black smoke (BS), as well as the daily number of deaths have been collected. Generalised linear models extending Poisson regression were applied. The e.ects of time trend, seasonal variations, days of the week, temperature, humidity and air pressure were adjusted. The per cent increase in the daily number of total deaths associated with a 10 μg/m3 increase in BS was 1.13% (0.08–2.20%). The e.ect size was slightly higher for cardiovascular mortality (1.25%, 95% CI: 0.53–1.97%). There was no signi.cant association between air pollution and respiratory mortality. These results indicate that current levels of ambient BS have signi.cant e.ects on total and cardiovascular mortalities in Nis.

Study aim: To determine muscle strength variables in elite judoists and wrestlers since thigh muscle strength and bilaterally balanced flexor-to-extensor ratio minimise injury risk and are desirable for achieving sport successes.Material and methods: Judoists, wrestlers and untrained subjects, 10 each, were subjected to isokinetic strength measurements of relative peak torques of knee flexor and extensor muscles on "Easy-Tech" dynamometer in concentric-concentric mode.Results: Mean relative peak muscle torques for knee flexors ranged from 1.14 ±0.27 (untrained) to 1.57 ±0.40 (judoists) N·m/kg and for knee extensors from 2.77 ± 0.34 (untrained) to 3.60 ± 0.64 (wrestlers) N·m/kg. The flexor-to-extensor ratios ranged from 39.3 ± 6.0 to 47.8 ± 10.8% and did not differ significantly between groups. Absolute right/left asymmetry for knee flexors ranged from 14.6 ± 10.4 to 17.4 ± 11.8% and was significantly (p<0.01) higher than for knee extensors (7.2 ± 6.8 to 8.6 ± 7.7%). All asymmetry indices were significant (p<0.01), no significant between group differences being detected.Conclusions: Implementing new training elements and modalities may improve the performance and prevent lateral asymmetry thus decreasing the risk of injuries.
