This article presents examples of  probing functions construction with a small width of autocorrelation function (a noise-like signal, a chirp signal) of long duration, which allows to obtain a reflectivity profile along a high resolution path. Attention is drawn to the fact that space in the process of probe pulse propagation returns to the receiver in an almost mutual correlation function of reflectivity and probe pulse. This approach opens up new possibilities for filtering signals and recognizing targets with appropriate selection and changing shape of the probe pulse right during measurements.

Regular exercise during school hours is encouraged since childhood obesity has reached epidemic proportions. Moreover, a great majority of adolescents do not meet the recommendations for moderate-to-vigorous physical activity. The present study aimed to determine the effects of school-based high-intensity interval training (HIIT) and nutrition intervention on body composition and physical fitness in overweight adolescent girls. Forty-eight girls were included in the study, of whom 24 (age = 15.5 ± 0.7 years) were randomized to a experimental group (EXP) (HIIT and nutrition intervention school-based program) and 24 (age = 15.7 ± 0.6 years) to a control group (CON) that maintained their usual physical education activities. HIIT consisted of 10 stations of own bodyweight exercise and was done three times per week for eight weeks. Moreover, the EXP participated in the nutrition program led by a nutritionist two times a week. Apart from body composition assessment, participants performed countermovement jump (CMJ), medicine ball throw, hand-grip test, and Yo-Yo Intermittent Recovery Level 1 Test (YYIRT1). A significant effect of group (EXP vs. CON) x time (pre vs. post) interaction was observed for weight [F(1,44) = 7.733; p = 0.008], body mass index [F(1,44) = 5.764; p = 0.020], body fat (in kg) [F(1,44) = 17.850; p < 0.001], and body fat (in %) [F(1,44) = 18.821; p < 0.001]. Moreover, a significant interaction was observed for the medicine ball throw [F(1,44) = 27.016; p < 0.001] and YYIRT1 [F(1,44) = 5.439; p = 0.024]. A significant main effect for time was found for hand grip [F(1,44) = 9.300; p = 0.004] and CMJ [F(1,44) = 12.866; p = 0.001].The present study has demonstrated that just eight weeks school-based HIIT and nutrition intervention, including three sessions a week, can improve body composition and muscular and physical aerobic performance in overweighted adolescent girls.

Trained Runners

The purpose of this study was to compare physical fitness levels of trained runners with mild mental retardation (MMR) (7 males and 2 females, age = 28.7 ± 7.4 years, weight = 67.0 ± 11.7 kg) and those without (7 males and 2 females, age = 29.1 ± 7.5, weight = 68.7 ± 8.8 kg). Paired t tests revealed no differences between runners with and without MMR on measures of V̇O2peak (56.3 ± 9.1 vs. 57.7 ± 4.1 ml · kg-1 · min-1), percent body fat (16.6 ± 8.4 vs. 16.6 ± 3.1), and lower back/hamstring flexibility (33.1 ± 10.9 vs. 28.6 ± 10.1 cm). Knee flexion (KF) and extension (KE) strength were significantly greater in runners without MMR compared to those with MMR (KF peak torque = 65.7 ±7.9 vs. 48.7 ± 15.7 ft/lb; KE peak torque = 138.5 ± 17.7 vs. 104.4 ± 29.9 ft/lb). It was concluded that trained runners with MMR can achieve high levels of physical fitness comparable to individuals without MMR.
