Project description:Maximal aerobic exercise capacity (V̇O2max) is one of the strongest predictors of morbidity and mortality. Aerobic exercise training can increase V̇O2max, but inter-individual variability is marked and unexplained physiologically. The mechanisms underlying this variability have major clinical implications for extending human healthspan. Here, we report the first comprehensive, RNA-seq study of circulating transcriptome signatures related to ΔV̇O2max. We used RNA-seq to characterize transcriptomic predictors of ΔV̇O2max in healthy women who completed a 16-week, randomized controlled trial comparing higher vs. lower aerobic exercise training volume and intensity (four training groups, fully crossed). We found striking baseline gene expression differences in subjects who responded to aerobic exercise training with robust (R) vs. little/no (NR) ΔV̇O2max.

Project description:Skeletal muscle adapts to exercise training of various modes, intensities and durations with a programmed gene expression response. This study dissects the independent and combined effects of exercise mode, intensity and duration to identify which exercise has the most positive effects on skeletal muscle health. Full details on exercise groups can be found in: Kraus et al Med Sci Sports Exerc. 2001 Oct;33(10):1774-84 and Bateman et al Am J Cardiol. 2011 Sep 15;108(6):838-44. This study uses a middle aged group of subjects that have 3+ markers of metabolic syndrome. One group remains an inactive control, while 5 groups undergo 9 mo supervised exercise training. Exercise groups are as follows: Inactive control (group B); Mild aerobic exercise - low amount/mod intensity (group A); Moderate aerobic exercise - low amt/vig intensity (group D); High aerobic exercise - high amt/vig intensity (group C); resistance training only (group F); and mod aerobic + resistance training (group E). Each group has 10 subjects (5 men and 5 women), however 3 subjects failed array QC, leaving 8 subjects in group E and 9 subjects in group F. Data were all analyzed pre to post training in a RM ANCOVA, covaried for age and sex or regression to determine genotype/phenotype interactions.

Project description:This 12-week, exercise study will assess the feasibility of a home-based high-intensity interval training (HIIT) program among colorectal cancer survivors and explore the impact of home-based HIIT compared to a standard home-based moderate-intensity continuous aerobic exercise program on physical outcomes linked with survival from colorectal cancer and surrogate blood markers of colorectal cancer recurrence.
HIIT is a type of aerobic exercise that includes short bursts (i.e. 1-4 minutes) of vigorous exercise followed by longer periods of moderate to lower intensity exercise (i.e. 1-10 minutes). Participants in this study will be randomly assigned into a personalized home based exercise program - either high-intensity interval training (HIIT) or moderate-intensity continuous aerobic exercise (MICE).
This pilot study will provide us with preliminary evidence for a larger trial aimed to compare the effectiveness of these two different types of home-based exercise programs on physical outcomes linked with survival, quality of life, and surrogate blood markers of colorectal cancer recurrence.

Project description:High intensity aerobic exercise (90% of the maximum heart rate) can effectively suppress cancer proliferation in vivo. However, the molecular effect of aerobic exercise and its relevance to cancer prevention remains uninvestigated. The mRNA-sequencing technique (mRNA-seq) can provide a genome-wide depiction of gene expression changes by aerobic exercise. Mice with colorectal cancer were subjected to high intensity aerobic exercise, and mRNA-seq analysis was performed on heart, lung, and skeletal muscle tissues to analyze the molecular effects of the exercise in a genome-wide manner. The skeletal muscle-derived genes with exercise-dependent differential expressions were further evaluated for their effects on colorectal cancer cell viability. Regular and high intensity aerobic physical activity in the mice produced positive results in comprehensive parameters (i.e., food intake, weight, and survival rate) compared to those in the control groups (healthy and cancer with no exercise). A heatmap of differentially expressed genes revealed markedly different expression patterns between these groups. RNA-seq analysis of 23,282 skeletal muscle-derived genes identified a number of anticancer effector genes. Knockdown and overexpression of selected anticancer genes significantly repressed CT26 proliferation by 20% (p<0.05). Our finding based on the aerobic exercise cancer mouses model suggest that the high intensity exercise resulted in a global change in gene expression patterns, particularly those that affect cancer cell viability.

Project description:To determine the efficacy and potential protective mechanism of canagliflozin combined with aerobic exercise in treating chronic heart failure (CHF).During 10 days, isoproterenol (5 mg/kg/d) was injected into rats to create CHF models. The rats were then randomized into four groups and administered with saline, canagliflozin (3 mg/kg/d), aerobic exercise training, and canagliflozin combined with aerobic exercise training. Then, we performed gene expression profiling using the data obtained by RNA-seq in the Control, HF, LC and LC-AE groups.

Project description:Interventions: Exercise intervention
Participants will be offered two supervised exercise sessions/week throughout the course of their chemotherapy treatment plus 2 weeks (max. 8 months). The exercise sessions will be conducted in small groups under the direct supervision of an exercise physiologist (EP) and last approximately 60 minutes. Prior to commencing the program, each participant will receive a consultation with the EP (as part of their baseline assessment) in order to individualise the exercise prescription to their specific needs according to their cancer and general health history, and physical abilities. The individualised prescription (i.e. specific exercise selection, intensity and progression) will be designed in accordance with national and international guidelines for best practice in exercise prescription for people with cancer, involving a combination of aerobic, resistance, and balance exercise (American College of Sports Medicine, Clinical Oncology Society of Australia, Exercise and Sports Science Australia). Specifically, the aerobic exercise component will include 20 to 25 minutes of moderate intensity continuous to vigorous intensity cardiovascular exercise (~60-85% of estimated maximum heart rate) using a variety of modes such as walking or jogging on a treadmill or cycling on a stationary ergometer. Participants will be encouraged to undertake additional home-based aerobic exercise with the goal of achieving a total of at least 150 minutes of moderate to vigorous intensity aerobic exercise each week. The resistance exercise component will last approximately 25 minutes and involve 4-6 exercises that target the major upper and lower body muscle groups (e.g. chest press, leg press). Intensity will be manipulated from 6-12 repetition maximum (RM; i.e. the maxi
Primary outcome(s): Chemotherapy completion rate will be assessed as the relative dose intensity (RDI) extracted from patient medical records.[Post-assessment: following adjuvant chemotherapy (within 4 weeks of the last chemotherapy cycle) or 8 months after the first exercise session, whichever comes first.]
