Cardiometabolic Correlates of Physical Activity and Sedentary Patterns in U.S. Youth.
Daily or weekly averages of physical activity and sedentary behavior could mask patterns of behavior throughout the week that independently affect cardiovascular health. We examined associations between day-to-day physical activity and sedentary behavior latent classes and cardiovascular disease (CVD) risk factors in U.S. youth. ⋯ There is some indication that patterns, in addition to the total amount of physical activity and sedentary behavior, may be important for cardiovascular health in youth. Longitudinal studies are needed to examine associations between physical activity and sedentary behavior patterns and changes in CVD risk factors.

Effect of Different Osmolalities, CHO Types, and [CHO] on Gastric Emptying in Humans.
This study investigated the effect of beverage osmolalities, carbohydrate (CHO) type, and CHO concentration on gastric emptying in euhydrated subjects at rest. ⋯ These data suggest that glucose exerts a stronger inhibitory stimulus compared with sucrose on gastric emptying and that a physiological threshold exists for the combined influence of glucose concentration and beverage osmolality to trigger the feedback inhibition of gastric emptying.

Exercise-Induced Hypoalgesia Is Not Influenced by Physical Activity Type and Amount.
Physical activity (PA), especially vigorous-intensity PA, has been shown to be related to pain sensitivity. The relationship among PA levels and PA types on endogenous pain inhibition after exercise, termed exercise-induced hypoalgesia (EIH), remains unclear.

Acute Effects of Low-Load/High-Repetition Single-Limb Resistance Training in COPD.
Exercising small muscle groups at a time allows higher muscle specific workloads compared with whole body aerobic exercises in people with chronic obstructive pulmonary disease (COPD). Whether similar effects also occur with partitioning exercise during low load/high-repetition resistance exercises is uncertain.
