I have not done a workout in 2 weeks. In order to “make room” in my schedule to speak at the 21 Convention I had to stack up shifts before and after the trip. As usual Anthony did a very professional job and treated everyone in attendance like royalty. I got to see Anthony, Skyler Tanner, Bill DeSimone, Eric Daniels, and James Steele. I arrived late Friday and had to leave early Sunday, so I missed seeing Drew Baye and Ellington Darden.
Since I do not (yet) have a workout to post, I wanted to put something up to reboot the discussion. Of all the clients we train at UE, probably the most marked improvements have been seen in clients with neurodegenerative diseases, especially Parkinson’s disease. My own father died of the complications of Parkinson’s disease in 2004. He was diagnosed when he was my age and remained fairly robust into his 70′s and only showed rapid decline in his 80′s. Nonetheless, it did have marked effects on his physical abilities as time went by. I wish I had known earlier what a difference strength training would have made for him. I was deeply involved in HIT ever since the early days of his diagnosis, but never once considered that it was something I should get him to try. Perhaps he gave me the “vibe” that he was not interested, but it was much more likely that I was simply a self-absorbed teenager (and later, a self-absorbed adult). All I can say is that now having seen what strength training does for people with Parkinson’s, I can say that not bringing it to my “Pop” stands as one of my biggest regrets. I was deluded to think that some people may have lost to much ground to strength train, when in fact those that have lost the most ground are the ones who stand to gain the most.
As a demonstration of this fact, I offer the following study on high intensity exercise in Parkinson’s patients. In particular, pay attention to the incredible percentage increases in performance across multiple domains. How many studies ever demonstrate this kind of improvement?

Novel, high-intensity exercise prescription improves muscle mass, mitochondrial function, and physical capacity in individuals with Parkinson’s disease.

We conducted, in persons with Parkinson’s disease (PD), a thorough assessment of neuromotor function and performance in conjunction with phenotypic analyses of skeletal muscle tissue, and further tested the adaptability of PD muscle to high-intensity exercise training. Fifteen participants with PD (Hoehn and Yahr stage 2-3) completed 16 wk of high-intensity exercise training designed to simultaneously challenge strength, power, endurance, balance, and mobility function. Skeletal muscle adaptations (P < 0.05) to exercise training in PD included myofiber hypertrophy (type I: +14%, type II: +36%), shift to less fatigable myofiber type profile, and increased mitochondrial complex activity in both subsarcolemmal and intermyofibrillar fractions (I: +45-56%, IV: +39-54%). These adaptations were accompanied by a host of functional and clinical improvements (P < 0.05): total body strength (+30-56%); leg power (+42%); single leg balance (+34%); sit-to-stand motor unit activation requirement (-30%); 6-min walk (+43 m), Parkinson’s Disease Quality of Life Scale (PDQ-39, -7.8pts); Unified Parkinson’s Disease Rating Scale (UPDRS) total (-5.7 pts) and motor (-2.7 pts); and fatigue severity (-17%). Additionally, PD subjects in the pretraining state were compared with a group of matched, non-PD controls (CON; did not exercise). A combined assessment of muscle tissue phenotype and neuromuscular function revealed a higher distribution and larger cross-sectional area of type I myofibers and greater type II myofiber size heterogeneity in PD vs. CON (P < 0.05). In conclusion, persons with moderately advanced PD adapt to high-intensity exercise training with favorable changes in skeletal muscle at the cellular and subcellular levels that are associated with improvements in motor function, physical capacity, and fatigue perception
