Accumulated Short Bouts of Walking in Older Adults With Type 2 Diabetes: Effects on Glycosylated Hemoglobin (HbA1c) and Homeostasis Model Assessment of Insulin Resistance (HOMA-IR).

The current study examined the effects of accumulated short bouts of walking on glycosylated hemoglobin (HbA1c) and homeostasis model assessment of insulin resistance (HOMA-IR) of older adults with type 2 diabetes. Differences in variables between models of accumulated bouts of walking and 10,000 steps were also investigated. Sedentary participants ( = 38) were randomized into one of three groups: accumulated 10-minute bouts of walking at 100 steps/min (10/100MW), accumulated 10,000 steps (10KS), or control.

The influence of low-impact dance intervention on bone metabolism, cognition, and function fitness of old women.

This study examined the low-impact dance intervention on the markers of bone metabolism, cognitive function, and functional fitness of postmenopausal women. Senior women were randomized into low-impact dance (LG) or control group (CG). Three dance sessions weekly were scheduled in the LG for 16 weeks.

Effects of Single Versus Multiple Bouts of Resistance Training on Maximal Strength and Anaerobic Performance.

This study examined the effects of one single bout daily versus triple bouts of resistance exercise for 12 weeks on muscular strength and anaerobic performance of the upper body. Twenty young male adults (age: 22.0 ± 1.

Effects of Low-Impact Dance on Blood Biochemistry, Bone Mineral Density, the Joint Range of Motion of Lower Extremities, Knee Extension Torque, and Fall in Females.

The effect of low-impact dance on blood metabolites, the joint range of motion (ROM) of the lower extremities, knee extension torque, bone mass density (BMD), the number of falls, and the confidence to perform daily activities (Modified Falls Efficacy Scale [MFES]) was examined in older sedentary women (age: 59 ± 4 years) before and after a 16-week intervention. Results showed that the average score for the MFES, some parameters of blood chemistry, and joint ROM were significantly improved after low-impact intervention. In addition to improvements in blood lipids and body fat percentages, the increases shown in the parameters regarding the lower extremities may contribute to confidence in performing common daily activities in older women, although the number of falls did not significantly differ between the two groups during the 16-week period.

Effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) levels.

We investigated the effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) concentrations. Eighteen male participants completed two different exercise sessions with intensities of 25% and 65% maximal aerobic capacity (VO2max). In addition to the energy expenditure during exercise sessions being measured, blood samples were collected before exercise, and immediately, at 24 h, and at 48 h post-exercise to analyse sOB-R, leptin and insulin levels.

Effects of sweet cassava polysaccharide extracts on endurance exercise in rats.

Background: Sweet cassava tubers have abundant carbohydrates consisting of monosaccharides and polysaccharides. In addition, polysaccharides extracted from plants improve sports performance, according to recent studies. We therefore examined whether the administration of sweet cassava polysaccharides (SCPs) benefited endurance performance in rats

Methods: Male Sprague-Dawley rats (n = 30, 7 weeks old) were divided into three groups: control (C), exercise (Ex), and exercise plus SCPs administration (ExSCP) (at a dose of 500 mg/kg body weight by gastric intubation for six days in addition to standard rat food and water).

Effects of different exercise intensities with isoenergetic expenditures on C-reactive protein and blood lipid levels.

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions.

The effects of low-impact dance on knee torque and lower extremity mobility in middle-aged and older women.

Background: Although low-impact dance is one of the most prevalent exercises in older persons, little is known about its effects on knee torque and range of motion (ROM) in lower extremity joints.

Purpose: The aim of this study was to examine the effects of low-impact dance on knee torque and lower extremity joint ROM in older women.

Methods: Twenty-six low-impact dancers and 12 physically inactive individuals comprised the dance group (DG) and the control group (CG), respectively.
