Exercise and progressive supranuclear palsy : the need for explicit exercise reporting

Background Progressive Supranuclear Palsy (PSP) is the most frequent form of atypical Parkinsonism. Although there is preliminary evidence for the benefits of gait rehabilitation, balance training and oculomotor exercises in PSP, the quality of reporting of exercise therapies appears mixed. The current investigation aims to evaluate the comprehensiveness of reporting of exercise and physical activity interventions in the PSP literature. Methods Two independent reviewers used the Consensus on Exercise Reporting Template (CERT) to extract all exercise intervention data from 11 studies included in a systematic review. CERT items covered: ‘what’ (materials), ‘who’ (instructor qualifications), ‘how’ (delivery), ‘where’ (location), ‘when’, ‘how much’ (dosage), ‘tailoring’ (what, how), and ‘how well’ (fidelity) exercise delivery complied with the protocol. Each exercise item was scored ‘1’ (adequately reported) or ‘0’ (not adequately reported or unclear). The CERT score was calculated, as well as the percentage of studies that reported each CERT item. Results The CERT scores ranged from 3 to 12 out of 19. No PSP studies adequately described exercise elements that would allow exact replication of the interventions. Well-described items included exercise equipment, exercise settings, exercise therapy scheduling, frequency and duration. Poorly described items included decision rules for exercise progression, instructor qualifications, exercise adherence, motivation strategies, safety and adverse events associated with exercise therapies. Discussion The results revealed variability in the reporting of physical therapies for people living with PSP. Future exercise trials need to more comprehensively describe equipment, instructor qualifications, exercise and physical activity type, dosage, setting, individual tailoring of exercises, supervision, adherence, motivation strategies, progression decisions, safety and adverse events. Conclusion Although beneficial for people living with PSP, exercise and physical therapy interventions have been inadequately reported. It is recommended that evidence-based reporting templates be utilised to comprehensively document therapeutic exercise design, delivery and evaluation

Physical training and high protein diet improved muscle strength, parent-reported fatigue and physical quality of life in children with Pompe disease

Exercise has proven to be an effective adjuvant treatment to enzyme replacement therapy (ERT) in mildly affected adult Pompe patients. The aim of this study was to investigate the effects of a 12-week tailored lifestyle intervention, consisting of physical training and a high protein diet (2 grams/kg), in children with Pompe disease. This randomized controlled semi-crossover trial investigated the effects of a lifestyle intervention on the primary outcome: exercise capacity. Secondary outcomes were: muscle strength, core stability, motor function, physical activity levels, quality of life, fatigue, fear of exercise, caloric intake, energy balance, body composition, and safety. Fourteen Pompe patients with a median age of 10.6 [IQR: 7.2-14.5], of whom six classic infantile patients, participated in the lifestyle intervention. At baseline, patients had a lower exercise capacity compared to healthy peers (median 70.3% [IQR: 54.8%-98.6%] of predicted). After the intervention, absolute Peak VO 2 improved significantly (1279 mL/min [1012.5-2006] vs. 1352 mL/min [1101.5-2069], p = 0.039), but not compared to the control period. Muscle strength of the hip flexors, hip abductors, elbow extensors, neck extensors, knee extensors, and core stability improved significantly compared to the control period. Children reported a significant increase on the change in health domain of quality of life, parents reported significantly better scores on the quality of life domains: physical functioning, change in health, family cohesion, and fatigue. A 12-week tailored lifestyle intervention for children with Pompe disease seemed safe and led to improvements in muscle strength, core stability, quality of life, and parent-reported fatigue. Pompe patients with a stable disease trajectory seemed to benefit the most from the intervention

Sestrins are evolutionarily conserved mediators of exercise benefits.

Exercise is among the most effective interventions for age-associated mobility decline and metabolic dysregulation. Although long-term endurance exercise promotes insulin sensitivity and expands respiratory capacity, genetic components and pathways mediating the metabolic benefits of exercise have remained elusive. Here, we show that Sestrins, a family of evolutionarily conserved exercise-inducible proteins, are critical mediators of exercise benefits. In both fly and mouse models, genetic ablation of Sestrins prevents organisms from acquiring metabolic benefits of exercise and improving their endurance through training. Conversely, Sestrin upregulation mimics both molecular and physiological effects of exercise, suggesting that it could be a major effector of exercise metabolism. Among the various targets modulated by Sestrin in response to exercise, AKT and PGC1α are critical for the Sestrin effects in extending endurance. These results indicate that Sestrin is a key integrating factor that drives the benefits of chronic exercise to metabolism and physical endurance
