OBJECTIVES: This investigation examined the effect of 6 months high‐ or low‐intensity resistance exercise on muscular strength and endurance stair climbing ability in adults aged 60 to 83. DESIGN: A randomized controlled trial. SETTING: University Florida Center for Exercise Science PARTICIPANTS: Sixty‐two men women completed study protocol. Subjects were matched randomly assigned a control (n = 16), (LEX, n 24), high‐intensity (HEX, 22) group. INTERVENTION: Six progressive, whole‐body...

Previous studies have indicated that patients with panic disorder are more likely than normal subjects to acute attacks during inhalation of CO2, but methodological objections been raised. In this study the authors attempted address three these problems by ensuring raters who assessed whether occurred were blind subjects' diagnoses, randomizing order administration 5% CO2 and hyperventilation, challenging a greater number 7% CO2.Patients underwent 20-minute inhalations 15 minutes room-air...

We examined the effects of 3 days exercise in a cold environment on expression left ventricular (LV) heat shock proteins (HSPs) and contractile performance during vivo ischemia-reperfusion (I/R). Sprague-Dawley rats were divided into following three groups ( n = 12/group): 1) control, 2) (60 min/day) at 4°C (E-Cold), 3) 25°C (E-Warm). Left anterior descending coronary occlusion was maintained for 20 min, followed by 30 min reperfusion. Compared with control group, both E-Cold E-Warm higher P...

Endurance exercise provides cardioprotection against ischemia-reperfusion (I/R) injury. Exercise-induced is associated with increases in cytoprotective proteins, including heat shock protein 72 (HSP72) and antioxidant enzyme activity. On the basis of reported half-life these putative cardioprotective we hypothesized that exercise-induced I/R injury would be lost within days after cessation exercise. To test this, male rats (4 mo) were randomly assigned to one five experimental groups: 1)....

Abstract It is well established that both short‐term (1–5 days) and long‐term (weeks to months) high intensity exercise (i.e. 70–75% V O 2max ) provides cardioprotection against ischaemia‐reperfusion injury. However, it unclear if moderate will also provide cardioprotection. Aim: Therefore, these experiments compared the protective effects of vs. in providing defense Methods: Male Sprague–Dawley rats were randomly assigned one three‐experimental groups: (1) sedentary (control); (2) treadmill...

Metalloproteinases (MMPs) are proteolytic enzymes that function in the extracellular matrix to degrade connective tissues. While it is clear exercise-induced injury skeletal muscle promotes increased expression of MMPs, relationship between exercise intensity and MMPs muscles unknown. These experiments tested hypothesis metalloproteinases (MMP-2 MMP-9) dose-dependent such high-intensity endurance increases MMP whereas low-intensity will not promote muscles. Female rats (4 months old)...

Aims: This study aimed to describe glucose variability (GV) and explore postprandial glycaemia the association with food composition following breakfast in children young people (CYP) type 1 diabetes (T1D). Methods: was an observational of CYP aged 1–17 years using continuous monitoring (CGM). Retrospective CGM data were collected assess GV along questionnaires about meal 4‐h period for 7 days. Statistical analysis included Student’s t ‐tests linear mixed models. Results: Ninety‐six...

Endurance exercise provides cardioprotection against ischemia-reperfusion-induced myocardial stunning and infarction. A recent study demonstrates that an exercise-induced increase in manganese superoxide dismutase (MnSOD) activity is essential to protect the heart It unknown if elevation cardiac MnSOD also a prerequisite achieve protection stunning. Therefore, this determined requirement Adult male rats remained sedentary or performed successive bouts of endurance exercise. Hearts were...

It has previously been shown that high dietary salt impairs vascular function independent of changes in blood pressure. Rodent studies suggest NADPH-derived reactive oxygen species mediate the deleterious effect on vasculature, and here we translate these findings to humans. Twenty-nine healthy adults (34 ± 2 yr) participated a controlled feeding study. Participants completed 7 days low-sodium diet (LS; 20 mmol sodium/day) high-sodium (HS; 300 random order. All participants were resistant,...

The influence of dietary sodium and potassium on blood pressure (BP) has been extensively studied, however their impact endothelial function, particularly any interactive effects, received less attention. purpose this study was to determine if can offset the deleterious effect high function independent BP. Thirty-three adults with salt-resistant BP (16 M 17 F; 27 ± 1 year) completed seven days each following diets in a random order: moderate potassium/low diet (65 mmol potassium/50 sodium;...
