where umm, wmax are given real numbers. Such a control is further denoted as an admissible one. Finally, x e R" is the vector of state variables and x0 e R" is the given initial state of the system. More general forms of bilinear systems are described in [3]. Examples of practical application of bilinear systems are presented in [3], [4], [5]. In this paper special representation for trajectori...

Supplemental oxygen has acute beneficial effects on exercise performance in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to investigate whether oxygen-supplemented training enhances the effects of training while breathing room air in patients with severe COPD. A randomized controlled trial was performed in 24 patients with severe COPD who developed h...

ObjectivesThis study aimed to investigate whether supplementation with 12 mg⋅day−1 astaxanthin for 7 days can improve exercise performance and metabolism during a 40 km cycling time trial.DesignA randomised, double-blind, crossover design was employed.MethodsTwelve recreationally trained male cyclists (VO2peak: 56.5 ± 5.5 mL⋅kg−1⋅min−1, Wmax: 346.8 38.4 W) were recruited. Prior each experimenta...

PURPOSE Beta-alanine (BA) supplementation has been shown to augment muscle carnosine concentration, thereby promoting high-intensity (HI) exercise performance. Trained muscles of athletes have a higher increase in carnosine concentration after BA supplementation compared to untrained muscles, but it remains to be determined whether this is due to an accumulation of acute exercise effects or to ...

In this paper, we deal with a certain type of automated food packing system with n hoppers. The system repeats throwing some amount of foods into empty hoppers to make all hoppers full of foods, and collecting the foods from several hoppers to pack them into a single package. We treat foods thrown into each hopper as an item i with an integer weight wi. Given a set I of n items in the hoppers, ...

The majority of patients with cystic fibrosis (CF) will grow into adulthood. Despite this improvement in survival, the disease is progressive, especially with respect to the decline in pulmonary function, which in turn may have an impact on a patient's quality of life. In this study we evaluated the quality of life in CF adults and examined the relationship between quality of life and pulmonary...

Increases in cardiorespiratory coordination (CRC) after training with no differences in performance and physiological variables have recently been reported using a principal component analysis approach. However, no research has yet evaluated the short-term effects of exercise on CRC. The aim of this study was to delineate the behavior of CRC under different physiological initial conditions prod...

This study examined acute hormone and force responses and strength and endurance performance and muscle hypertrophy before and after 24 weeks of same-session combined strength and endurance training in previously untrained women. Subjects were assigned 1 of 2 training orders: endurance preceding strength (E + S, n = 15) or vice versa (S + E, n = 14). Acute force and hormone responses to a combi...
