Study aim: the aim of study was assessment somatic features and selected cardio-ventilatory indices in men above 50 years old with different physical activity levels.
Materials and methods: the study included 55 men on average aged 54.5 ± 4.32, classified to the trained group (T), n = 33, and not trained group (NT), n = 22. Total physical activity was assessed using the SDPAR Questionnaire. Measurements: anthropometric indices, ventilatory indices and VO2 peak, hemodynamic indices and fatigue using Borg scale during exercise maximal test.
Results: daily energy expenditures for sport and recreation differ significantly between T and NT groups, 6.82 METs vs. 0.2 METs, respectively (p < 0.001). Men in T and NT groups significantly differ in somatic features, and cardio-pulmonary indices including: time of physical tests effort (s) 1103 ± 193 vs. 681 ± 328; max speed (km/h) 14 ± 1.5 vs. 10 ± 1.4, VE peak 135.9 ± 21.17 l/min vs. 112.9 ± 21.49 l/min; VO2 peak 61.8 ± 8.83 ml/kg/min vs. 41.9 ± 8.55 ml/kg/min; HR rest (beat/min) 69 ± 16.95 vs. 83 ± 14.48; HR peak (beat/min) 171 ± 1.23 vs. 163 ± 15.28; SV peak (ml) 162 ± 24.23 vs. 135 ± 33.22; CO peak 27.4 ± 4,3 vs. 21.6 ± 5.17.
Conclusions: men aged 50+ who practice running training differ favourably and significantly from men not trained in anthropometric as well as cardio-ventilatory indices. Significant correlations were found between DEE and FAT(%), VO2 peak (ml/kg/min), SV peak (ml) and COpeak (l/min) as well between CO peak and VO2peak was record linear relationship (r = 0.56).
