Mobile awareness systems provide user-controlled and automatic, sensor-derived cues of other users’ situations and in that way attempt to facilitate group practices and provide opportunities for social interaction. We are interested in investigating how users interpret these cues as a situation, action, or intention of a remote person and then act on them in everyday social interactions. Three ...

PURPOSE High-intensity interval training (HIIT) is documented to yield effective improvements in the cardiovascular system and be an excellent strategy for healthy aging. However, it is not determined how age may affect the training response of key components of aerobic endurance. METHODS We recruited 72 males (mean ± SD, weight = 84.9 ± 12.9 kg, height = 180.4 ± 5.8 cm) and 22 females (weigh...

In the setting of "living high," it is unclear whether high-intensity interval training (HIIT) should be performed "low" or "high" to stimulate muscular and performance adaptations. Therefore, 10 physically active males participated in a 5-week "live high-train low or high" program (TR), whilst eight subjects were not engaged in any altitude or training intervention (CON). Five days per week (~...

Methods Ten obese men participated in cross-over 4-week moderate(MIIT) and high(HIIT) intensity interval cycling. MIIT consisted of 5-min stages at ±20% of mechanical work at 45 %VO2peak, and HIIT consisted of 30-sec work at 90 %VO2peak and 30-sec rests for 30-45 min. The assessments included a constant-load test consisted of 5-min rest, 45-min cycling at 45 %VO2peak followed by 60-min recovery...

PURPOSE The present study investigated the effects of high-intensity intermittent training (HIIT) on lower- and upper-body graded exercise and high-intensity intermittent exercise (HIIE, four Wingate bouts) performance, and on physiological and muscle damage markers responses in judo athletes. METHODS Thirty-five subjects were randomly allocated to a control group (n = 8) or to one of the fol...

AIM Our study aimed to investigate changes of different markers for routine assessment of fatigue and recovery in response to high-intensity interval training (HIIT). METHODS 22 well-trained male and female team sport athletes (age, 23.0 ± 2.7 years; V̇O2 max, 57.6 ± 8.6 mL · min · kg(-1)) participated in a six-day running-based HIIT-microcycle with a total of eleven HIIT sessions. Repeated sp...

Background: High Intensity Interval Training (HIIT) is an aerobic exercise consisting of high intensity physical interspersed with low exercise. HIIT has been known that can improve cognitive function. Medical students activity affect on function including short-term memory. Short-term memory important in learning process which academic performance. Objective: To determine the effect individual...

the aim of this study was to determine time dependent effects of high intensity interval training (hiit) on oxygen kinetics in young males. 40 active students were randomly assigned to four groups: one session of hiit, two sessions of hiit, four sessions of hiit and control. both hiit and control groups performed the incremental test on an ergometer bicycle. two days after the pretest, training...

BACKGROUND Although evidence shows the positive health effects of physical activity, most of the adult population in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle behaviours. This protocol describes a study in which we will compare the effects of 12 weeks of high-intensity interval training (HIIT), resistance training (RT) or comb...

Purpose: Develop a prediction equation for critical power (CP) and work above CP (W') in hypoxia for use in the work-balance ([Formula: see text]) model. Methods: Nine trained male cyclists completed cycling time trials (TT; 12, 7, and 3 min) to determine CP and W' at five altitudes (250, 1,250, 2,250, 3,250, and 4,250 m). Least squares regression was used to predict CP and W' at altitude. A hi...
