BACKGROUND Little is known about factors affecting adherence to highly-structured and supervised exercise programs in older people. METHODS Healthy, inactive older (≥65 y) women (N = 30) were randomized into a 1) higher- (ATH-80% VO₂peak); 2) moderate- (ATM-65% VO₂peak) intensity aerobic; or 3) lower-intensity resistance (RTL; 50% VO₂peak) group. All 3 groups exercised 4 days·week⁻¹ for an av...

Jogging and walking are the most common aerobic exercises engaged in by numbers of people at different intensity and duration. The problem of this study is that most Exercisers find the choice of jogging at high intensity or walking for long duration difficult to make. This paper reviews research works on physiological effects of jogging at high intensity and walking for long duration. These in...

The tolerable duration of continuous high-intensity exercise is determined by the hyperbolic Speed-tolerable duration (S-tLIM) relationship. However, application of the S-tLIM relationship to normalize the intensity of High-Intensity Interval Training (HIIT) has yet to be considered, with this the aim of present study. Subjects completed a ramp-incremental test, and series of 4 constant-speed t...

Stress patterns in language play a large role in how we perceive speech. Stress is assigned on the basis of duration, intensity, and F0. This study investigated the role that duration, intensity, and F0 play in rhythmic grouping. Subjects were presented with sequences of alternating squarewave segments that were varied on one of the aforementioned dimensions. They were asked to indicate whether...

OBJECTIVE To evaluate the intensity and duration of physical efforts in Physical Education classes in primary and secondary school. METHODS School-based cross-sectional study carried out by means of the observation of 218 Physical Education classes, including a total of 272 students (each one of the students was evaluated three times). The study was carried out in the city of Pelotas (Souther...

The regulation of endurance training is usually based on the prescription of exercise intensity. Exercise duration, another important variable of training load, is rarely prescribed by individual measures and mostly set from experience. As the specific exercise duration for any intensity plays a substantial role regarding the different kind of cellular stressors, degree, and kind of fatigue as ...

External electric field, which is applied to cells, can, under suitable field parameters, induce local distortions and structural rearrangements of lipid molecules in the cell membrane. Depending on the field parameters, the membrane hence becomes either transiently or permanently permeable even after the field has ceased, allowing molecules that are otherwise deprived of transport mechanisms t...

Postexercise fat oxidation may be important for exercise prescription aimed at optimizing fat loss. The authors examined the effects of exercise intensity, duration, and modality on postexercise oxygen consumption (VO2) and substrate selection/ respiratory-exchange ratio (RER) in healthy individuals. Three experiments (n = 7 for each) compared (a) short- (SD) vs. long-duration (LD) ergometer cy...

67 Abstract— This paper deals with a new embedded method for Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyo stimulation. It is the elicitation of muscle contraction using electric impulses. The EMS provides remote patient monitoring in healthcare field. The primary function of the system aims in designing an Electrical muscle stimula...

We examined the net catabolism of two pools of glycogen, proglycogen (PG) and macroglycogen (MG), in human skeletal muscle during exercise. Male subjects (n = 21) were assigned to one of three groups. Group 1 exercised 45 min at 70% maximal O(2) uptake (VO(2 max)) and had muscle biopsies at rest, 15 min, and 45 min. Group 2 exercised at 85% VO(2 max) to exhaustion (45.4 +/- 3.4 min) and had bio...
