Project description:Study the training exercise effects in chronic obstructive pulmonary disease (COPD) patients and aged-matched healthy individuals. Skeletal muscle biopsies from 9 stable COPD patients with normal fat free mass index (FFMI, 21Kg/m2) (COPDN), 6 COPD patients with low FFMI (16Kg/m2) (COPL), and 12 healthy sedentary subjects (FFMI 21Kg/m2) before and after 8 weeks of a supervised endurance exercise program were analyzed. Samples were collected from open biopsies from the musculus vastus lateralis of COPD patients and healthy individuals before and after 8 weeks of exercise training. Constant-work rate exercise at 70% of pre-training Watts peak (Wpeak) (CardiO2 cycle Medical Graphics Corporation, USA) was carried out before and after 8 weeks of supervised interval training with a cycloergometer until pre-training endurance time exhaustion. Measurements before and after training were obtained at isowork-rate and iso-time.
Project description:Study the effects of 3 weeks training exercise in chronic obstructive pulmonary disease (COPD) patients and healthy individuals. Skeletal muscle biopsies of 5 COPD patients (aged 63±2 year) and 3 age-matched healthy individuals were studied before and after 3 weeks of a supervised endurance training program. Samples were collected from open muscle biopsies of the vastus lateralis of 5 COPD patients and 3 age-matched healthy individuals before and after 3 weeks of a supervised endurance training program. Patients and controls underwent an endurance exercise program on a cycloergometer 5 days a week for three consecutive weeks. One 1 h session/day was established in all subjects, with effective exercise periods of at least 30 min in each case.

Project description:This study aimed to determine skeletal muscle DNA methylation changes in a cohort of volunteers with a range of insulin sensitivities following 8-weeks of supervised exercise training. We studied 13 sedentary participants (5M/8F, 34.6 ± 3.1 years) and performed euglycemic hyperinsulinemic clamps with vastus lateralis muscle biopsies and peak aerobic activity (VO2 peak) tests before and after training. We extracted DNA from the muscle biopsies and performed global methylation using Illumina's Methylation EPIC 850K BeadChip.
Project description:We assessed vastus lateralis muscle gene expression levels of 12 women with the metabolic syndrome before and after a 6 month exercise training program RNA was isolated from a vastus lateralis muscle biopsy of 6 women with the metabolic syndrome before and after a 6 month guided endurance exercise training program
Project description:Skeletal muscle unloading due to joint immobilization induces skeletal muscle atrophy. However, the skeletal muscle proteome response to limb immobilization has not been investigated using SWATH methods. This study quantitatively characterized the muscle proteome at baseline, and after 3 and 14 d of unilateral lower limb (knee-brace) immobilization in 18 healthy young men (25.4 ±5.5 y, 81.2 ±11.6 kg). All muscle biopsies were obtained from the vastus lateralis muscle. Unilateral lower limb immobilization was preceded by four-weeks of exercise training to standardise acute training history, and 7 days of dietary provision to standardise energy/macronutrient intake. Dietary intake was also standardised/provided throughout the 14 d immobilization period.
