Correlation between the rate of weight loss and changes in body composition in obese postmenopausal

Correlation between the rate of weight loss and changes in body composition in obese postmenopausal women after 5 weeks: a pilot study.
Approximately 25% of weight lost during restrictive diets (without exercise) is lean body mass (LBM). No study has yet investigated the impact of the rate of weight loss (RWL) on LBM […]

Parents report intrapersonal, interpersonal, and environmental barriers to supporting healthy eating

Parents report intrapersonal, interpersonal, and environmental barriers to supporting healthy eating and physical activity among their preschoolers.
There is an increasing trend in childhood obesity in Canada and many preschool children are overweight or obese. The objective of this study was to explore parents\’ experiences and challenges in supporting healthy eating and physical […]

Reproducibility of short-term food intake and subjective appetite scores after a glucose preload, ve

Reproducibility of short-term food intake and subjective appetite scores after a glucose preload, ventilation threshold, and body composition in boys.
The objective of these studies was to assess the reproducibility of (i) short-term food intake (FI) and subjective appetite following a glucose preload, (ii) ventilation threshold (VT) and subjective appetite after short-duration exercise, […]

Adding carbohydrate to a high-fat meal blunts postprandial lipemia in women and reduces meal-derived

Adding carbohydrate to a high-fat meal blunts postprandial lipemia in women and reduces meal-derived fatty acids in systemic circulation.
The lipemic response to a meal is an important independent risk factor for the development of cardiovascular disease. The purpose of this study was to determine the effect of adding carbohydrate (CHO) to a […]

Relationship between the metabolic syndrome and physical activity energy expenditure: a MONET study.

Relationship between the metabolic syndrome and physical activity energy expenditure: a MONET study.
The purpose of this cross-sectional study was to examine the association between the metabolic syndrome (MetS) and physical activity energy expenditure (PAEE) in overweight and obese sedentary postmenopausal women. The study population consisted of 137 overweight and obese sedentary postmenopausal […]

The time course of denervation-induced changes is similar in soleus muscles of adult and old rats.

The time course of denervation-induced changes is similar in soleus muscles of adult and old rats.
Muscle denervation is accompanied by atrophy and a decline in oxidative capacity. We investigated whether the time course of adaptations following denervation of the soleus muscle differs in adult (5 months old) and older adult (25 months […]

Anaerobic performance when rehydrating with water or commercially available sports drinks during pro

Anaerobic performance when rehydrating with water or commercially available sports drinks during prolonged exercise in the heat.
The effects that rehydrating drinks ingested during exercise may have on anaerobic exercise performance are unclear. This study aimed to determine which of four commercial rehydrating drinks better maintains leg power and force during prolonged cycling […]

Plasma lipoprotein (a), homocysteine, and other cardiovascular disease (CVD) risk factors in Nigeria

Plasma lipoprotein (a), homocysteine, and other cardiovascular disease (CVD) risk factors in Nigerians with CVD.
Elevated plasma lipoprotein (a) (Lp(a)) and total homocysteine (tHcy) concentrations, as well as fat distributions, are associated with cardiovascular disease (CVD) risk. The purpose of this study was to evaluate plasma Lp(a), tHcy, percentage body fat, anthropometric indices, […]

Influence of fiber-type composition on recovery from tourniquet-induced skeletal muscle ischemia-rep

Influence of fiber-type composition on recovery from tourniquet-induced skeletal muscle ischemia-reperfusion injury.
This study was designed to determine if previously reported differences in the functional impairment of muscles composed of predominantly different fiber types occurs following extended periods of ischemia. We hypothesized that the soleus (Sol) muscle, a predominantly slow-twitch muscle, would be […]

Sweat rate, salt loss, and fluid intake during an intense on-ice practice in elite Canadian male jun

Sweat rate, salt loss, and fluid intake during an intense on-ice practice in elite Canadian male junior hockey players.
Previous research in many sports suggests that losing ~1%-2% body mass through sweating impairs athletic performance. Elite-level hockey involves high-intensity bursts of skating, arena temperatures are >10 degrees C, and players wear protective equipment, […]
