Physical activity, ambulation, and comorbidities in people with diabetes and lower-limb amputation.

We characterized physical activity (PA) and its relation to physical function and number of comorbidities in people with diabetes and transtibial amputation (AMP), people with diabetes without AMP, and nondisabled adults without diabetes or AMP. Twenty-two individuals with type 2 diabetes mellitus (DM) and transtibial amputation (DM+AMP), 11 people with DM, and 13 nondisabled participants were recruited for this cross-sectional cohort study. Measures included PA volume and intensity, a Timed Up and Go test, a 2-min walk test, and number of comorbidities.

Lower limb neuromuscular function and blood flow characteristics in AFO-using survivors of stroke.

Background And Purpose: Ankle-foot orthoses (AFOs) and gait aids are commonly used by survivors of stroke to ambulate, but they have not been used as inclusion or exclusion criteria for physiological studies. The purpose of this study was to examine differences in neuromuscular function and blood flow characteristics between the lower limbs of ambulatory, AFO-using survivors of stroke (n = 9).

Methods: The subjects were, on average, 14 years poststroke and had used an AFO for about 7 years.

Differences in tibia morphology between the sound and affected sides in ankle-foot orthosis-using survivors of stroke.

Objective: To examine differences in tibia and proximal femur morphology between the affected and sound limbs in ankle-foot orthosis (AFO)-using survivors of stroke.

Design: Observational study.

Setting: A university bone density laboratory.

Effects of resistance training duration on muscular strength retention 6-month posttraining in older men and women.

Background And Purpose: Older individuals are at a greater risk for falling, and this risk has been linked to age-related declines in strength and balance. It has been demonstrated that older individuals can increase strength and function from properly designed, supervised training programs; however, little is known about the regressive effects of a detraining period in this participant population once the training intervention has ended. This study examined changes in strength 6 months after training following a 40- or 80-week supervised progressive resistance training program.

Hormone responses to a continuous bout of rock climbing in men.

Rock climbing is rapidly increasing in popularity as a recreational activity and as a competitive sport. Few studies have tested acute physiological responses to climbing, and no studies to date have tested hormone responses to a climbing-based workout. This study aimed to measure testosterone (T), growth hormone (GH), and cortisol (C) responses to continuous vertical climbing in young male rock climbers.
