Abstract: This application provides methods of increasing vascularization, muscle performance, muscle rehabilitation, and/or mitochondrial activity in subjects in need thereof, by administering a therapeutically effective amount of one or more agents that increases ERR? activity to the subject. Such agents can include one or more ERR? agonists. In some examples the method does not require that the subject exercise, and as such, the subject may be sedentary (such as bedridden or in a wheelchair).

Abstract: Disclosed herein are methods of improving muscular health, such as enhancing muscle regeneration, maintenance, or repair. In some examples, the method includes administering to the subject an effective amount of an agent capable of increasing activity or expression of estrogen receptor-related gamma (ERR?), related receptors ERR? or ?, or ERR-regulated metabolic and angiogenic genes, thereby enhancing muscle regeneration, maintenance, or repair. In some examples, the methods are utilized to treat a subject with one or more signs or symptoms of muscular dystrophy, such as, but not limited to Duchenne muscular dystrophy. In some examples, the disclosed methods further include selecting a subject in need of enhancing muscle regeneration, maintenance, or repair.

Abstract: Provided herein are methods and compositions for improving muscle performance and increasing endurance. Agonists of AMP-activated protein kinase (AMPK) and agonists of peroxisome proliferator-activated receptor delta (PPAR?) can be used in such treatments.

Abstract: Disclosed herein are methods for enhancing one or more effects of exercise in a subject by administering a PPAR? agonist (e.g., GW1516) to the subject in combination with an exercise program. Also disclosed are gene expression profiles unique to the combination of agonist-induced PPAR? activation and exercise. Such profiles are useful, at least, in methods for identifying the use of performance-enhancing drugs in exercised subjects (such as, professional or athletes). Direct interactions between PPAR? and exercised-induced kinases (e.g., AMPK or its subunits, AMPK ?1 and/or AMPK ?2) also are disclosed. Such protein-protein interactions provide new targets for identification of useful compounds.

Abstract: This disclosure concerns the use of agonists of AMP-activated protein kinase (AMPK) for improving exercise and modifying energy metabolism in a subject. The disclosure also relates to a combination of AMPK and peroxisome proliferator-activated receptor (PPAR) ? agonists for improving exercise performance in a subject, methods for identifying substance-enhanced exercise performance in a subject, and methods for identifying compounds that affect the interaction of PPAR? with exercise-induced kinases.
