Self-paced exercise is less physically challenging than enforced constant pace exercise of the same intensity: influence of complex central metabolic control.

Objective: To examine whether self-pacing reduces the physiological challenge of performing 5000 m rowing ergometry exercise in comparison with a matched-intensity exercise condition in which a constant effort pacing strategy is enforced.

Methods: Nine healthy well-trained male participants volunteered to participate in three 5000 m rowing conditions (two submaximal and one maximal conditions) in an individualised order. In the submaximal conditions, participants were required to (1) perform 5000 m at a constant rating of perceived exertion (RPE 15-Hard) (SubRPE) or (2) perform 5000 m at an enforced constant pace equivalent to the mean power output (PO) of the SubRPE condition (SubEXT).

Changes in body composition in patients with left ventricular systolic dysfunction initiated on beta-blocker therapy.

Background: Increasing body mass index, cholesterol and body fat are associated with a better prognosis in patients with left ventricular systolic dysfunction (LVSD). Beta-blocker usage is associated with changes in body composition and increased body fat. The present study investigated 12-month changes in body composition in patients with LVSD initiated on beta-blocker therapy.

The lived experiences of people diagnosed with multiple sclerosis in relation to exercise.

The purpose of this study was to examine the lived experiences of people diagnosed with Multiple Sclerosis (MS). Seven active exercisers with MS participated in semi-structured interviews regarding their exercise experiences since diagnosis. Data were analysed using Interpretative Phenomenological Analysis (IPA; Smith  & Osborn, 2003 ).

Concurrent inspiratory muscle and cardiovascular training differentially improves both perceptions of effort and 5000 m running performance compared with cardiovascular training alone.

Objective: To examine whether inspiratory muscle training (IMT) is a useful additional technique with which to augment cardiovascular exercise training adaptations.

Methods: 16 healthy untrained males agreed to participate in the study and were randomly assigned to training (TRA; n = 8) and placebo (PLA; n = 8) groups. Pre- and post-training measurements of spirometry and maximal inspiratory mouth pressure (MIP) were taken in addition to i) maximal aerobic power (VO(2max)) and ii) 5000 m run time-trial.

Season-to-Season Variations of Physiological Fitness Within a Squad of Professional Male Soccer Players.

The purpose of this study was to examine season-to-season variations in physiological fitness parameters among a 1(st) team squad of professional adult male soccer players for the confirmatory purposes of identifying normative responses (immediately prior to pre-season training (PPS), mid-season (MID), and end-of-season (EOS)). Test-retest data were collected from a student population on the primary dependent variables of anaerobic threshold (AT) and maximal aerobic power (VO2 max) to define meaningful measurement change in excess of test-retest technical error between test-to-test performances. Participants from a pool of 42 professional soccer players were tested over a set sequence of tests during the 3-year period: 1) basic anthropometry, 2) countermovement jump (CMJ) tests 3) a combined AT and VO2 max test.
