Unlabelled: This study investigated the effects of a beet nitric oxide enhancing (NOE) supplement comprised of nitrite and nitrate on cycling performance indices in trained cyclists.

Methods: Subjects completed a lactate threshold test and a high-intensity interval (HIIT) protocol at 50% above functional threshold power with or without oral NOE supplement.

Results: NOE supplementation enhanced lactate threshold by 7.

The present investigation examined the ability of two threshold detection analyses (maximum distance, Dmax; modified maximum distance, mDmax) in identifying the near-infrared spectroscopy (NIRS) threshold, a lactate threshold (LT) estimate, from exercising tissue oxygen saturation (StO) responses. Additionally, the test-retest reliability of exercising StO and total hemoglobin concentration (THC) responses were examined at moderate and peak cycling intensities. Fourteen healthy, recreationally active participants performed maximal incremental step cycling tests (+25 W / 3 minutes) to volitional fatigue on two separate occasions while StO and THC of the vastus lateralis were monitored.

This study determined the reliability of measuring resting metabolic rate (RMR) with COSMED's FitMate™ metabolic system using a canopy dilution set-up compared with a previously validated COSMED QUARK CPET research-based system in 30 healthy adults (age: 28.4 ± 7.0 yrs, weight: 79.

Background: Neuromuscular fatigue is a common complaint in Crohn's disease (CD) patients. A correlation between serum vitamin D concentrations and neuromuscular function has been found in the elderly or non-ambulant populations.

Aims: The aim of this study was to determine whether CD patients exhibit impaired neuromuscular function and if so, is there a link between vitamin D and neuromuscular function.

Aerobic exercise training is used for rehabilitation in patients with chronic obstructive pulmonary disease (COPD), although it has little effect on muscle weakness and atrophy. Resistance training may be a useful addition to aerobic programs for these patients. The purpose of the present study was to investigate the effects of resistance training in addition to aerobic training on functional outcomes in patients with COPD.

Purpose: To investigate the influence of intensity versus total energy expenditure on neutrophilia and blood oxidative stress to acute exercise.

Methods: Nine males (18-30 yr) completed one maximal (Max) and three submaximal exercise sessions: 1) 45 min at 10% above (LT+) lactate threshold (LT), 2) 45 min at 10% below (LT-) LT, and 3) 10% below LT until caloric expenditure equaled the 10%+ trial (LT-kcal). Blood was sampled before (PRE), immediately (POST), 1 h, and 2 h after exercise to measure neutrophils, myeloperoxidase, superoxide (O(2)-), neutrophil activation (O(2)-/neutrophils), ascorbic acid, uric acid, malondialdehyde, and lipid hydroperoxides.

The purpose of the study was to determine the accuracy of 11 prediction equations in estimating the 1 repetition maximum (1 RM) bench press from repetitions completed by collegiate football players (N = 69) using 225 lb. The demographic variables race, age, height, weight, fat-free weight, and percent body fat were measured to determine whether these variables increased the accuracy of the prediction equations; race was the most frequently selected variable in the regression analyses. The validity of the prediction equations was dependent upon the number of repetitions performed, i.

Androstenedione, 4-androstenediol, 5-androstenediol, 19-norandrostenediol and 19-norandrostenedione are commonly referred to as "Andro" prohormones. Over the last few years, supplementation using these prohormones has been aggressively marketed to the general public. Supplement manufacturers often claim that Andro use improves serum testosterone concentrations, increases muscular strength and muscle mass, helps to reduce body fatness, enhances mood, and improves sexual performance.
