Zhen Yan recommends strength and endurance exercise for healthy aging. Here is a practical reading for racquet players, with mitoAMPK research in context.
On Oct. 28, 2026, WDBJ reported that Zhen Yan of the Fralin Biomedical Research Institute at Virginia Tech recommended combining resistance training and endurance exercise for healthy aging.
Yan directs the institute’s Center for Exercise Medicine Research. In the WDBJ report, he said regular exercise activates a molecular system called mitoAMPK and spoke favorably about tennis and pickleball. His practical message was to exercise regularly, choose enjoyable activities and avoid rushing into exercise.
The recommendation sits alongside his research into exercise-related signals in muscle cells. Virginia Tech reports that Yan’s group identified a pool of AMPK molecules on the outer mitochondrial membrane. The researchers call it mitoAMPK and suggest that its location may allow more precise signaling related to mitochondrial quality and quantity.
According to Virginia Tech, researchers already knew that the AMPK type dominant in skeletal muscle switches on during endurance exercise. Its activation has been shown to improve mitochondrial quantity and quality over time. Yan’s work examines the significance of where this signaling happens.
For an elite player, the question might be whether this research could eventually inform preparation or performance. A weekend league player has a more immediate question: how should the recommendation shape the way they view their overall exercise routine?
Evercourts’ reading is that the useful takeaway concerns training balance rather than a new competitive advantage. Yan’s recommendation gives adult players a reason to consider court activity alongside resistance exercise. It is not a reason to turn every match into a laboratory experiment or judge a session by an invisible cellular response.
Virginia Tech explains that AMPK responds to changes in AMP and ADP, molecules associated with cellular energy use. AMPK signaling can direct cells to remove old mitochondria and build new ones. That helps explain the researchers’ interest in both mitochondrial quantity and quality rather than simply having more mitochondria.
In an experiment Yan recounted to WDBJ, mice fed a high-fat diet that had access to running wheels had better-looking skeletal-muscle mitochondria than mice without that access. This was an animal example, not a demonstration of the same outcome in human racquet-sport players.
Neither report provides a human trial testing a particular combination of resistance exercise and court play for disease prevention or longer life. Neither supplies an exercise dose, session length or progression method. The practical recommendation therefore remains Yan’s expert guidance rather than a tested racquet-sport training protocol.
The clearest application is to look at the whole exercise routine rather than count matches alone. A busy court calendar answers the question of how often someone plays. It does not, by itself, answer whether resistance exercise has a place in that person’s routine.
For an adult player reviewing their approach, the distinction can be framed through a few planning questions:
These are planning questions, not a prescribed workout. They reflect Yan’s recommendation to combine exercise types without attaching an unsupported schedule to it. The aim is to keep both parts visible when thinking about preparation.
Tennis and pickleball were the sports Yan spoke favorably about in the WDBJ interview. For padel players, applying the same broad planning principle is an editorial interpretation of his recommendation rather than a padel-specific research finding. The report does not rank the sports or establish that one delivers a better mitochondrial response.
Evercourts’ strength-training resource for racquet-sport players provides a separate place to consider that side of preparation. The news itself is a prompt to give strength work attention alongside enjoyable court activity, not a replacement for individual planning.
Yan’s advice to enjoy exercise deserves as much attention as the molecular terminology. As reported by WDBJ, his message was about regular activity rather than pursuing a complicated exercise formula. For recreational players, that is a useful editorial emphasis: consider the routine you want to sustain rather than chase the newest scientific label.
“The biggest enemy of exercise is injury,” Yan told WDBJ. He cautioned against rushing into exercise and getting hurt. Read that as a warning against urgency, not as a promise that any particular preparation method will prevent injury.
There is no need to interpret the interview as a demand to add harder training immediately. Its practical value is in the combination Yan recommends and the caution he attaches to it. Decisions about returning after an injury or exercising with a health condition belong with a qualified healthcare professional who can consider the individual situation.
For the broader planning discussion, Evercourts’ resource on managing the demands of training and court time offers another point of reference. Keep that discussion distinct from the molecular findings: the interview supplies a direction of thought, not a personal training schedule.
There is also a treatment-research story to watch. WDBJ reported that Yan’s team was studying and modifying a drug intended to mimic exercise. Virginia Tech describes potential therapeutic applications for mitoAMPK. That work remains a research direction, not an available treatment or a demonstrated substitute for exercise.
Over the next season, the most useful development would be evidence connecting these molecular findings with clearly described human exercise programs and meaningful outcomes. For court players, future reporting will be more informative if it explains who was studied and what exercise they performed. It should also distinguish a cellular change from an improvement in health or playing capacity.
The editorial priority should remain proportionate: follow the science without letting an emerging mechanism dictate the training calendar. Yan’s present recommendation is straightforward enough to understand without mastering mitochondrial biology. Give enjoyable court activity and resistance exercise a place in the same conversation, with the long view of continuing to play.
