Much recent interest has focused on the relationship between physical activity and health and supported with an abundance of scientific evidence. However, the concept of Exercise is Medicine™copromoted by the American College of Sports Medicine and American Medical Association and similar august bodies worldwide is far from new— the importance of exercise for health has been reported for centuries. Participation in regular physical activity and exercise provides numerous benefits for health with such benefits typically varying according to the volume completed as reflected by intensity, duration, and frequency. Evidence suggests a dose–response relationship such that being active, even to a …

Abstract Background Exercise has shown positive training effects on obesity-related inflammation, however, resistance training has shown mixed results concerning adipocytokine levels. Aims The purpose of thispilot study was to explore the effects of resistance training on blood adipocytokine concentrations in obese youth, with specific examination of the relationship between these biomarkers and improved fitness (i.e., aerobic capacity, muscular strength). Methods Fourteen obese adolescents (16.1 ± 1.6 y; BMI: 32.3 ± 3.9 kg/m2) participated in a 16-week resistance training intervention. Body composition, fasting blood concentrations of interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α), adiponectin, and leptin were measured pre- and post-training. Aerobic …

Background: Gastric emptying (GE) could influence exercise-induced changes in appetite and energy intake. GE also could contribute tochanges in gastric symptoms and the availability of nutrients during exercise, which will subsequently affect performance. Objective: The objective of this review was to determine the effects of acute exercise on GE using a systematic review and meta-analysis. The most common parameters to determine GE were selected, consisting of half-emptying time and volume emptied. Oral-caecal transit time (OCTT) was also examined. Data Sources: Research databases (PubMed, Scopus, Google Scholar, EBSCOhost, SPORTDiscus) were searched through November 2013 for original studies, abstracts, theses and dissertations …

Acute Interval Exercise Intensity Does Not Affect Appetite And Nutrient Preferences In Overweight And Obese Males, Shaea Alkahtani, Nuala Byrne, Andrew Hills, Neil King

This study investigated the influence of two different intensities of acute interval exercise on food preferences and appetite sensations in overweight and obese men. Twelve overweight/obese males (age=29.0±4.1 years; BMI =29.1±2.4 kg/m2) completed three exercise sessions: an initial graded exercise test, and two interval cycling sessions: moderate-(MIIT) and high-intensity (HIIT) interval exercise sessions on separate days in a counterbalanced order. The MIIT session involved cycling for 5-minute repetitions of alternate workloads 20% below and 20% above maximal fat oxidation. The HIIT session consisted of cycling for alternate bouts of 15 seconds at 85% VO2max and 15 seconds unloaded recovery. Appetite …

Purpose: Compensatory responses may attenuate the effectiveness of exercise training in weight management. The aim of this study was to compare the effect of moderate- and high-intensity interval training on eating behavior compensation. Methods: Using a crossover design, 10 overweight and obese men participated in 4-week moderate (MIIT) and high (HIIT) intensity interval training. MIIT consisted of 5-min cycling stages at ±20% of mechanical work at 45%VO2peak, and HIIT consisted of alternate 30-s work at 90%VO2peak and 30-s rests, for 30 to 45 min. Assessments included a constant-load exercise test at 45%VO2peak for 45 min followed by 60-min recovery. Appetite …
