Physical training has been shown to be important to the control of muscle mass during aging, through the activation of several pathways including, IGF1-AKT and PGC-1α. Also, it was demonstrated that LRP130, a component of the PGC-1α complex, is important for the PGC-1α-dependent transcription of several mitochondrial genes in vivo. To explore the role of physical training during aging, we investigated the effects on muscle recovery after short-term immobilization followed by 3 or 7 days with aerobic or resistance training.

Article Synopsis
- This study evaluated how a GaAs laser impacts muscle regeneration following a cryoinjury in Wistar rats, comparing groups receiving different treatments.
- Rats were divided into three groups: a control group, an injured group, and a group that received laser treatment after the injury.
- The results indicated that the laser-treated group had more regenerating muscle fibers and lower levels of inflammation markers, suggesting that laser therapy may aid in muscle recovery without altering collagen remodeling.
Heart failure (HF) is characterized by limited exercise tolerance, skeletal muscle atrophy, a shift toward fast muscle fiber, and myogenic regulatory factor (MRF) changes. Reactive oxygen species (ROS) also contribute to target organ damage in this syndrome. In this study, we investigated and compared morphofunctional characteristics and gene expression in Soleus (SOL--oxidative and slow twitching muscle) and in Extensor Digitorum Longus (EDL--glycolytic and fast twitching muscle) during HF.
