We examined mixed-muscle and fiber type-specific responses to a single session 12 wk of moderate-intensity continuous training (MICT) sprint interval (SIT) in humans. Both interventions elicited generally similar responses, although the training-induced increases type I fiber-specific markers mitochondrial content were greater MICT than SIT. These findings advance our understanding potential role changes determining human skeletal muscle response intermittent exercise.
Abstract Background Accelerometery is commonly used to estimate physical activity, sleep, and sedentary behavior. In free-living conditions, periods of device removal (non-wear) can lead misclassification behavior with consequences for research outcomes clinical decision making. Common methods non-wear detection are limited by data transformations (e.g., activity counts) or algorithm parameters such as minimum durations absolute temperature thresholds that risk over- under-estimating time....
We examined the effect of brief intermittent stair climbing exercise on glycemic control using continuous glucose monitoring in people with type 2 diabetes (n = 7, 5 men; women; age, 21-70 years). The protocol involved three 60-s bouts vigorously ascending and slowly descending a flight stairs. Mean 24-h blood was unchanged after an acute session (p 0.43) following 18 sessions over 6 weeks 0.13). well tolerated by participants but seemingly insufficient to alter control.
Abstract Background Recent technological advances have led to a surge in the use of wearable devices for personal health and fitness monitoring; however, clinical uptake remote or ‘free-living’ measurement daily health-related behavior has lagged. To advance field, there is need valid reliable outcomes across multiple domains specific cohorts patients interest centralized tools build capacity these data. The NiMBaLWear pipeline provides flexible integrated approach wearables analytics...
Accurate measurement of daily physical activity (PA) is important as PA linked to health outcomes in older adults and people living with complex conditions. Wrist-worn accelerometers are widely used estimate intensity, including walking, which composes much PA. However, there concern that wrist-derived data these cohorts unreliable due slow gait speed, mobility aid use, disease-related symptoms impact arm movement, transient activities living. Despite the potential for error intensity...
The legs of 9 men (age 21 ± 2 years, 45 4 mL/(kg·min)) were randomly assigned to complete 6 sessions high-intensity exercise training, involving either one or four 5-min bouts counterweighted, single-leg cycling. Needle biopsies from vastus lateralis revealed that citrate synthase maximal activity increased after training in the 4-bout group (p = 0.035) but not 1-bout 0.10), with a significant difference between groups post-training (13%, p 0.021). Novelty Short-term using brief intense...
There has been tremendous growth in wearable technologies for health monitoring but limited efforts to optimize methods sharing wearables-derived information with older adults and clinical cohorts. This study aimed co-develop, design evaluate a personalized approach information-sharing regarding daily health-related behaviors captured wearables.A participatory research was adopted with: (a) iterative stakeholder, evidence-led development of feedback reporting; (b) evaluation sample (n = 15)...
Mitochondrial dynamics, a process regulated by mitochondrial fission and fusion, is important for the maintenance of high quality mitochondria healthy metabolic function. Low-volume sprint interval training (SIT) increases content to similar extent as moderate-intensity continuous (MICT); however, limited data are available regarding effect these diverse approaches on dynamics proteins. Research has also relied primarily whole muscle analyses which may mask fiber-type specific adaptations....
