Study aim: To determine the effects of indoor cycling training combined with restricted diet, lasting 12 weeks, on serum lipid concentrations in obese women.Material and methods: Twenty women aged 23.8 ± 3.6 years were randomly assigned into two groups: control (C) and experimental (E), the latter subjected to indoor cycling at various loads, 3 sessions weekly, every session lasting 45 min, combined with restricted diet (about 1200 kcal daily) for 12 weeks. The following variables were recorded: body height and mass, BMI, relative body fat content (from 7 skinfolds), fat-free mass, triglycerides, cholesterol and lipoproteins (HDL, LDL, VLDL).Results: Significant increase in HDL and significant decreases in all other variables (except body height) were noted only in the experimental group.Conclusions: Indoor cycling associated with restricted diet is an excellent option in controlling obesity and serum lipids.

Study aim: To assess the acute effect of the proprioceptive neuromuscular facilitation method (PNF) on the explosive strength of lower extremities of male soldiers.Material and methods: A group of 26 male soldiers performed two exercise sessions on different days, in a random order: without stretching (control exercise) or by applying PNF (experimental exercise). Before and after the PNF (0, 10, 20, 40 and 60 min), 3 vertical counter-movement jumps on a tensometric platform were executed.Results: CMJ results in the experimental sessions were significantly (p<0.001) decreased after the PNF exertion in relation to the initial (pre-session) value. No significant post-session decreases were found in the control exercise. However, the differences between the experimental and control results were significant (p<0.05) only immediately after the PNF exertion and 10 min later.Conclusion: The PNF method negatively affects the vertical jump performance and, thus, ought not to be used as part of warm-ups.
