The effects of endurance training on endurance performance characteristics and cardiac autonomic modulation during night sleep were investigated during two 4-week training periods. After the first 4-week training period (3 x 40 min per week, at 75% of HRR) the subjects were divided into HIGH group (n = 7), who performed three high-intensity endurance training sessions per week; and CONTROL grou...

Nearly 50% of the horses participating in endurance events are eliminated at a veterinary examination (a vet gate). Detecting unfit horses before a health problem occurs and treatment is required is a challenge for veterinarians but is essential for improving equine welfare. We hypothesized that it would be possible to detect unfit horses earlier in the event by measuring heart rate recovery va...

Patients with multiple sclerosis (MS) show a poor exercise tolerance. A reduction in respiratory muscle strength has also been reported. The purpose of this study was to evaluate whether reduction in exercise tolerance was related to respiratory muscle dysfunction. Twenty four multiple sclerosis patients (mean +/- SD age: 48 +/- 9 yrs, duration of illness 12.2 +/- 6 yrs, severity of illness as ...

We evaluated the reliability of static and dynamic lumbar muscle endurance measurements on a BackUP lumbar extension dynamometer. Sixteen healthy participants (8 male; 8 female) volunteered for this investigation. Fifty percent of each participant's body weight was calculated to determine the weight load utilized for the static (holding time) and dynamic (repetitions) lumbar extension endurance...

Equivocal findings exist on the effect of concurrent strength (S) and endurance (E) training on endurance performance and muscle morphology. Further, the influence of concurrent SE training on muscle fiber-type composition, vascularization and endurance capacity remains unknown in top-level endurance athletes. The present study examined the effect of 16 weeks of concurrent SE training on maxima...

Physical exercise is used for the promotion and maintenance of good health and for the improvement of physical fitness. Both endurance and resistance exercises are needed to carry out a complete training program. Because time may be a barrier to physical exercise practice, the aim of this study was to verify whether the order of execution of endurance and resistance exercises, in concurrent tra...

The influence of supplemental oxygen on exercise performance was assessed in 17 patients with severe airflow obstruction. Exercise capacity was measured by the six minute walking distance, by an endurance walking test, and by an endurance cycling test and comparison was made with performance when the patient was breathing air. In addition, the relation between the flow rate of supplemental oxyg...

Overload is necessary in order to develop fitness in all exercise-related fitness components: cardiorespiratory (aerobic) endurance, muscular strength, muscular endurance and flexibility. According to the principle of overload, a person must work (load) the body in a higher manner than normal in order to improve fitness. For improved cardiorespiratory endurance via walking, for example, this me...

Structural, i.e. qualitative changes in some motor dimensions (strength and endurance) were assessed during a 2-month period in a sample of 307 male subjects, Croatian Navy draftees, mean age 21 years. Study subjects were divided into three groups: experimental group 1 (n = 102), experimental group 2 (n = 97) and control group (n = 108), submitted to different kinesiologic treatments. The struc...
