Intraspecific variation and trade-off in aerobic and anaerobic traits remain poorly understood in aquatic locomotion. Using gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata), both axial swimmers, this study tested four hypotheses: (1) gait transition from steady to unsteady (i.e., burst-assisted) swimming is associated with anaerobic metabolism evidenced as excess p...

The direct effects of physical activity interventions on energy expenditure are relatively small when placed in the context of total daily energy demands. Hence, the suggestion has been made that exercise produces energetic benefits in other components of the daily energy budget, thus generating a net effect on energy balance much greater than the direct energy cost of the exercise alone. Resti...

Recent investigations have shown excess postexercise oxygen consumption (EPOC) to be elevated for up to 48 hours in both untrained and trained subjects after resistance training (RT). The purpose of this study was to investigate the effect of load-volume on EPOC. Eight trained men (aged 22 ± 3 years) participated in 2 randomized RT bouts separated by at least 1 week with total load-volumes of 1...

The purpose of this study was to investigate the effects of 30-second all-out sprint interval exercise (SIE) vs. moderate aerobic exercise (MA) on excess post-exercise oxygen consumption (EPOC). Six recreationallytrained males (age=23.3±1.4 yrs, weight=81.8±9.9 kg, height=180.8±6.3 cm) completed a sprint interval exercise session consisting of three repeated 30-second Wingate cycling tests sepa...

La Obstrucción Recurrente de las Vías Aéreas (ORVA), conocida en ingles como RAO (Recurrent Airways Obstruction), es consecuencia de un proceso inflamatorio originado por una hipersensibilidad debida a la inhalación de agentes alergenos. Esta condición, debido a los mecanismos inmunológicos que intervienen en la patogénesis tiene alguna similitud con el asma humana. Esta patología también es co...

Introducción: La caminata de 6 minutos (C6M) es subutilizada en la actualidad, lo anterior al parecer, por poca disponibilidad espacio físico los centros atención salud. Realizar una forma alterna reproducible permitiría el estudio y seguimiento pacientes con enfermedad pulmonar obstructiva (EPOC).

the purpose of present study was to examine the effect of caffeine consumption on substrate metabolism and time to exhaustion during exercise and one hour after exercise in athletic female. eleven female athlete students (age 23±1.54 years, body weight 56.09±5.99 kg, and aerobic power 40.21±1.01ml/kg/min) volunteered and were randomly divided into three groups of control,placebo (starch capsule...
