Abstract. Studies of exercise in depression have not focused on persons already engaging in exercise. The current study aimed to provide an in-depth examination of exercise in depressive persons. In all, 62 depressive outpatients were compared with 62 parallelized nondepressive controls on various aspects of self-reported exercise (total amount, frequency, duration, intensity, type). Of the depressive participants, 52 % and of the nondepressive participants 76 % reported engaging in exercise. Compared with nondepressive exercisers, depressive exercisers exercised less (average total amount of

Abstract:

Imagery plays important cognitive and motivational roles in many areas of life, including sport (Paivio, 1985) and exercise (Hausenblas, Hall, Rodgers, & Munroe, 1999). The purpose of the present paper was to examine how the cognitive and motivational roles of exercise imagery vary with gender, frequency of exercise, and activity type. Participants (n = 577) completed the Exercise Imagery Questionnaire (Hausenblas et al„ 1999) which measures appearance, energy, and technique imagery. Participants, regardless of gender, frequency of exercise, or activity type, used appearance imagery most f

Abstract:

Sedentary aging leads to left ventricular (LV) and vascular stiffening due in part to advanced glycation end-products (AGEs) cross-linking of extracellular matrix proteins. Vigorous lifelong exercise ameliorates age-related cardiovascular (CV) stiffening and enhances exercise LV function, although this effect is limited when exercise is initiated later in life. We hypothesized that exercise training might be more effective at improving the impact of age-related CV stiffening during exercise when combined with an AGE cross-link breaker (Alagebrium). Sixty-two seniors (≥60 yr) were randomized in

Abstract:

1. The functional properties of tibialis anterior muscles of normal adult (C57BL/10) and age-matched dystrophin-deficient (C57BL/10 mdx) mice have been investigated in situ. Comparisons were made between tibialis anterior muscle strength, rates of force development and relaxation, force-frequency responses and fatiguability. Subjecting mdx and C57 muscles to a regimen of eccentric exercise allowed the hypothesis to be tested that dystrophin-deficient muscles are more susceptible to exercise-induced muscle damage. 2. mdx muscles were, on average, 30% stronger than C57 muscles and almost 80% hea

Abstract:

The majority of studies have routinely measured neuromuscular (NM) fatigue with a delay (∼1–3 min) after cycling exercises. This is problematic since NM fatigue can massively recover within the first 1–2 min after exercise. This study investigated the etiology of knee extensors (KE) NM fatigue and recovery kinetics in response to cycling exercises by assessing NM function as early as 10 s following cycling and up to 8 min of recovery. Ten young males performed different cycling exercises on different days: a Wingate (WING), a 10-min task at severe-intensity (SEV), and a 90-min task at moderate

Abstract:

The purpose of this study was to elucidate the influence of inspiratory muscle fatigue on muscle sympathetic nerve activity (MSNA) and blood pressure (BP) response during submaximal exercise. We hypothesized that inspiratory muscle fatigue would elicit increases in sympathetic vasoconstrictor outflow and BP during dynamic leg exercise. The subjects carried out four submaximal exercise tests: two were maximal inspiratory pressure (PImax) tests and two were MSNA tests. In the PImax tests, the subjects performed two 10-min exercises at 40% peak oxygen uptake using a cycle ergometer in a semirecum

Abstract:

The present study was to obtain basic data for applying the short stick exercises to frail elderly individuals. A total of 20 individuals aged ≥60 years (10 men, and 10 women) with independence in activities of daily living participated in a short stick exercise program. During the exercise program, the time required and the number of times the short stick was dropped were investigated. The exercise intensity was also evaluated based on expired gas and heart rate measurements. The mean exercise intensity of the short stick exercises was 1.9 ± 0.3 metabolic equivalents (METs), equivalent to tal

Abstract:

Mean normalized gain is able to detect differences in V̇O2p kinetics between moderate-, heavy-, and heavy-intensity exercises from a raised WR within the same individuals. This new method of kinetic analysis may be advantageous compared with conventional curve fitting, as it is less sensitive to breath-by-breath noise, it can provide useful information from a single exercise testing session, and it can be applied to nonconstant work rate exercise situations.

The heart rate response to vagal stimulation and the interaction with sympathetic activity was evaluated in conscious dogs at rest and during exercise; the latter was used as a tool to physiologically elevate sympathetic activity. In 20 dogs with a healed myocardial infarction and in 7 healthy dogs a bipolar electrode was chronically implanted around the right cervical vagus. Vagal stimulation (3 ms; 2.1 +/- 0.7 mA; 2, 4, 6, 8, 10, 12 Hz) was performed while dogs stood on the treadmill (heart rate 120 +/- 25 beats/min) and while they exercised (201 +/- 17 beats/min).

Abstract:

This laboratory exercise demonstrates fundamental principles of mammalian locomotion. It provides opportunities to interrogate aspects of locomotion from biomechanics to energetics to body size scaling. It has the added benefit of having results with robust signal to noise so that students will have success even if not “meticulous” in attention to detail. First, using respirometry, students measure the energetic cost of hopping at a “preferred” hop frequency. This is followed by hopping at an imposed frequency half of the preferred. By measuring the O2 uptake and work done with each hop, stude

After surgical construction of latissimus dorsi muscle ventricles, seven beagles underwent 31P-NMR spectroscopy during 12-min exercise protocols at 25- and 85-Hz stimulation frequencies and during both isovolumetric and dynamic contractions. Exercise at 85 Hz was associated with significantly greater fatigue than exercise at 25 Hz. At both frequencies, the onset of exercise was associated with a marked increase in inorganic phosphate (Pi) and a decr
