Project description:To investigate the influence of lifelong exercise training on the response of skeletal muscle to a bout of acute exercise we generated global transcriptomic data from long-term endurance (8 men, 8 women) and strength (8 men, 8 women) trained individuals and healthy age-matched untrained controls (8 men, 8 women). Skeletal muscle biopsies were taken from M. vastus lateralis before, directly after, and after 1h and 3hrs following acute exercise. All subjects completed one bout of acute endurance exercise and one bout of acute resistance exercise, separated by 4-8 weeks. All 384 samples were multiplexed in 4 lanes and sequenced (2x250bp paired end) on the Illumina NovaSeq 6000.

Project description:The aim of this investigation was to evaluate the effect of training on the global transcriptional response of skeletal muscle to an acute bout of resistance exercise. Seven young healthy men and women underwent a 12-week supervised progressive unilateral arm resistance exercise (RE) training program. One week after the last session of training, subjects performed an acute bout of bilateral arm RE in which the trained and the untrained arm exercised at the same relative intensity. A muscle biopsy was obtained 4h post exercise from the biceps brachii of the trained and untrained arm. Trained and untrained muscle samples were analyzed for mRNA levels of over 20,000 annotated genes using Affymetrix U133 Plus 2.0 microarrays.

Project description:STRRIDE is an exercise intervention study of different doses and intensities in overweight women and men with the metabolic syndrome. We profiled biopsies from 3 female and 3 male STRRIDE subjects in the “high” exercise group (2,200 kCal/wk). Muscle biopsies were profiled at entry (0h), and after 9 months of aerobic training (24 hrs post-last bout, 96 hrs post last bout, and 336h (14 days) de-training). Included also are pilot expression data from 3 male subjects. Keywords: other

Project description:We sought to determine skeletal muscle genome-wide DNA methylation and transcriptome changes to one bout of lower-load (LL) versus higher-load (HL) resistance exercise. Previously trained college-aged males (n=11, age: 23±4 years old, training experience: 4 ± 3 years) performed LL or HL bouts to failure separated by one week. The HL bout (a.k.a., 80 Fail) consisted of four sets of back squats and four sets of leg extensions to failure using 80% of their estimated one-repetition maximum (i.e., est. 1-RM from 3-RM testing), whereas the LL bout (a.k.a., 30 Fail) consisted of this same paradigm using 30% of their est. 1-RM. Vastus lateralis muscle biopsies were collected before, 3 hours, and 6 hours after each exercise bout. DNA and RNA were batch-isolated from muscle and analyzed for genome-wide DNA methylation and mRNA expression using the 850k Illumina MethylationEPIC array and Clariom S mRNA microarray, respectively. Although the total number of repetitions performed were significantly greater during the 30 Fail versus 80 Fail bout (p<0.001), total training volume (sets x reps x load) was not significantly different between conditions (p=0.571). Interestingly, 30 Fail led to decreased methylation across various promoter regions, albeit the transcriptome-wide responses between bouts were largely similar. According to bioinformatics, both bouts altered post-exercise mRNA profiles related to inflammatory signaling (e.g., Toll receptor, CCKR, chemokine and cytokine signaling), apoptosis, gonadotropin-releasing hormone, and integrin signaling. Also notable, more robust DNA methylation events occurred 3 hours versus 6 hours post-exercise regardless of bout (239,951 versus 12,419 CpG sites significantly hyper- or hypomethylated at these respective time points, p<0.01). Moreover, the percentage of significantly altered mRNAs that also demonstrated significantly inversed methylation patterns across one or more CpG sites was appreciably higher at 3 hours versus 6 hours following exercise (~75% versus ~15%, respectively). In conclusion, our transcriptomic data suggest that the molecular signaling events during the early post-exercise period are largely similar between LL and HL bouts, and this may explain why similar longer-term phenotypes (e.g., myofiber hypertrophy) result from these two training modalities. Additionally, our methylome data indicate that the majority of DNA methylation changes following an acute bout of resistance exercise occur rapidly (~3 hours) following exercise in previously trained men.

Project description:The study has been described in the following paper: Gianni Parise, Stuart M. Phillips, Jan J. Kaczor and Mark A. Tarnopolsky (2005). Antioxidant enzyme activity is up-regulated after unilateral resistance exercise training in older adults. Free Radical Biology and Medicine, Volume 39, Issue 2, 15 July 2005, Pages 289-295 We cite the following three paragraphs from this paper: "MATERIALS AND METHODS Subjects Twelve men (71.2 ± 6.5 y) volunteered to participate in a 12 week uni-lateral leg resistance training program (Table 1). All subjects underwent a thorough screening process before being admitted into the study. Subjects were first screened by telephone, and were then subject to a medical evaluation. Consent from their family physician was required, and then all potential subjects underwent a resting electrocardiogram, and a sub-maximal graded exercise test on a bicycle ergometer witih a 12-lead ECG. Exclusion criteria included: evidence of coronary hear disease; congestive heart failure; uncontrolled hypertension; chronic obstructive pulmonary disease; diabetes mellitus; renal failure; major orthopaedic disability; and smoking. None of the subjects had ever participated in a structured exercise program. After subjects were advised of the benefits and risks of participation, subjects gave their written informed consent. The study was approved by the McMaster University and Hamilton Health Sciences Research Ethics Board and conferred to the principles of the declaration of Helsinki. Exercise Training Resistance training was performed three times weekly on non-consecutive days (Monday, Wednesday, and Friday) for 12 weeks, under strict supervision. Prior to and after each training session subjects were required to perform passive stretching. Resistance exercise for each session consisted of 3 sets of 10 repetitions for each of leg press and leg extension. Training progressed from one set of each exercise at 50% of the initial 1 repetition maximum (1RM) to 3 sets at 80% of 1RM over the training period. Training logs were kept to record the volume and intensity of each session. The 1RM was re-evaluated every 2 weeks, and the training load was adjusted accordingly. All exercises were performed on universal strength training equipment (Universal Gym Equipment, Inc., Cedar Rapids, Iowa). Muscle Biopsy A muscle biopsy was taken from the vastus lateralis muscle of both legs before as well as after the training period, 20 cm proximal to the knee joint using a modified Bergström needle (5 mm diameter) with suction modification. The biopsy specimen was dissected of fat and connective tissue and immediately frozen in liquid nitrogen. All samples were stored at -80 °C for subsequent analysis. All subjects were required to abstain from strenuous physical activity for 48 hours prior to the testing session. The non-trained leg performed an acute bout of exercise at the same relative intensity of the training leg to allow for the determination of the effect of training and the effect of acute resistance exercise." Additional Notes: 1) The samples of 8 out 12 were used in the gene expression study. 2) The 2 factors in this study are: 2.1) Leg - Left or Right 2.2) Training - Baseline: samples taken on each leg before exercise - Resistance Training: one of the legs was subject to resistance training followed by acute exercise - Acute Exercise: the other leg had only the acute exercise 3) The baseline samples will be used for right versus left leg comparison to see variance between legs for human experimentation technical issues. The samples from Resistance or Acute Exercise will be compared to corresponding baseline samples to evaluate the effect of both exercise programs on gene expression.

Project description:The molecular mechanisms underlying the sex differences in human muscle morphology and function remain to be elucidated. The purpose of the study was to detect the sex differences in the skeletal muscle transcriptome in both the resting state and following anabolic stimuli, resistance exercise. We used microarrays to profile the transcriptome of the biceps brachii of young men and women who underwent an acute unilateral RE session following 12 weeks of progressive training. Bilateral muscle biopsies were obtained either at an early (4h post-exercise) or late recovery (24h post-exercise) time point. Muscle transcription profiles were compared in the resting state between men (n=6) and women (n=8), and in response to acute RE in trained exercised vs. untrained non-exercised control muscle for each sex and time point separately (4h post-exercise, n=3 males, n=4 females; 24h post-exercise, n=3 males, n=4 females). A logistic regression-based method (LRpath), following Bayesian moderated t-statistic (IMBT), was used to test gene functional groups and biological pathways enriched with differentially expressed genes.
