Whey protein improves glycemia during an oral glucose tolerance test compared to vigorous-intensity aerobic exercise in young adult men.

Background: Both aerobic exercise and whey protein can improve glucose regulation. The purpose of this study was to investigate how a single bout of vigorous-intensity aerobic exercise and whey protein, independently, as well as when combined, influence glycemia during an oral glucose tolerance test in sedentary, young men.

Methods: Healthy males (n = 11) completed four randomized trials: no exercise/no whey protein (R); exercise (EX; walking at 70% VO for 60 min); 50 g of whey protein (W); and exercise combined with 50 g of whey protein (EXW).

Pilot study: an acute bout of high intensity interval exercise increases 12.5 h GH secretion.

The purpose of this study was to test the hypothesis that high-intensity interval exercise (HIE) significantly increases growth hormone (GH) secretion to a greater extent than moderate-intensity continuous exercise (MOD) in young women. Five young, sedentary women (mean ± SD; age: 22.6±1.

Cardiorespiratory responses during aquatic treadmill exercise and land treadmill exercise in older adults with type 2 diabetes.

Background: The purpose of this study was to compare the effect of aquatic treadmill exercise (ATM) to land treadmill exercise (LTM) in adults with and without type 2 diabetes (T2D).

Methods: Five participants with T2D (4 females, 1 male; age=51±3 years; height=170±3 cm; weight=96±11 kg; body fat=32±1%) and five participants without T2D (4 females, 1 male; age=51±3 years; height=170±3 cm; weight=71±15 kg; body fat=27±2%) completed the study. Participants completed three, 5-minute stages of exercise at 3.

Vitamin D status, body composition, and fitness measures in college-aged students.

Low vitamin D, commonly assessed as serum 25-hydroxyvitamin D (25OHD), is associated with the development of many age-related chronic diseases. A positive relationship exists between elevated 25OHD and muscle synthesis, strength, power, and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger healthy populations.
