ABSTRACT Physical activity is known to influence and regulate leptin hormone secretion, which assists in the regulation of body weight and energy homeostasis. The purpose of the present study was to investigate the effects of a single session of concurrent exercise on leptin levels and insulin resistance, until 24 h post-exercise. Ten male subjects (22.9±1.7 years) healthy volunteer perf...

Plasma prolactin has been shown to increase during stress; the immune system is responsive to prolactin and affected by stress. Therefore, this study was undertaken to investigate the effects of acute graded, maximal treadmill exercise on prolactin-receptor expression by lymphocytes. Eight healthy men underwent one exercise and one nonexercise session. Blood was sampled immediately before and a...

parathyroid hormone (pth) is the major factor of calcium homeostasis. this hormone increases calcium uptake in intestines through stimulation of the active formation of vitamin d and eventually increases bone density. the aim of this study was to investigate the effect of one session of resistance and endurance activity on pth and alp in untrained young girls (mean age 21.9±1.23 yrs, height 161...

Habitual long term physical activity is known to have beneficial cognitive, structural, and neuro-protective brain effects, but to date there is limited knowledge on whether a single session of exercise can alter the brain's functional connectivity, as assessed by resting-state functional magnetic resonance imaging (rs-fMRI). The primary objective of this study was to characterize potential ses...

Background: One of the common socioeconomic problems of today’s world is back pain and its chronic type can cause severe pain and disability in patients. Aquatic exercise is one of the complementary therapies which are used in diseases treatments. Aim: To determine the effectiveness of aquatic exercise on pain intensity and disability of the patients with chronic low back pain. Methods: This ex...

Objective. To examine the effect of acute and short-term (~1 week) aerobic exercise training on plasma adiponectin levels in inactive, abdominally obese men. Materials and Methods. Inactive and abdominally obese men (n = 38, waist circumference ≥102 cm) recruited from Kingston, Canada were randomly allocated to perform three bouts of aerobic treadmill exercise at either low (50% VO(2) peak) or ...
