Effects of Androgenic-Anabolic Steroids in Athletes
TLDR
Although AAS administration may affect erythropoiesis and blood haemoglobin concentrations, no effect on endurance performance was observed and little data about the effects of AAS on metabolic responses during exercise training and recovery are available and, therefore, do not allow firm conclusions.
A new approach for the determination of ventilatory and lactate thresholds.
TLDR
The Dmax method appears to be an objective and reliable method for threshold determination, which can be applied to various ventilatory or metabolic variables yet yield similar results and showed that breathing frequency can be used to determine VT.
Whey protein stimulates postprandial muscle protein accretion more effectively than do casein and casein hydrolysate in older men.
TLDR
Whey protein stimulates postprandial muscle protein accretion more effectively than do casein and casein hydrolysate in older men, attributed to a combination of whey's faster digestion and absorption kinetics and higher leucine content.
Variability of aerobic performance in the laboratory and its physiologic correlates.
TLDR
The results suggest that the magnitude of physiologic responses to exercise isrelated to relative work load and that variability of physical performance is related to changes in gross mechanical efficiency.
Acid-base balance during repeated bouts of exercise: influence of HCO3.
TLDR
The alkalizing influence of oral HCO3 supports the concept that the hydrogen ion concentration in blood and muscle has a direct influence on performance during repeated, supramaximal exercise.
Physiological changes in male competitive cyclists after two weeks of intensified training.
TLDR
To study the physiological response to heavy training, seven male competitive cyclists intensified their normal training program for two weeks (IIT) in order to achieve a state of short-term overtraining, and all subjects showed symptoms of overtraining.
Training and overtraining: an introduction.

Elite sport requires high training volumes. However, little is known about the relationship between training volume and performance development. This relationship appears to have an inverted U-shape.
Exercise-induced muscle damage.

TLDR
Experimental evidence suggests that one bout of eccentric exercise has a long lasting protective effect against damage induced by a second bout of exercise, and this adaptation can partly be attributed to an increase in connective tissue.
Physiological, biochemical and psychological markers of strenuous training-induced fatigue.
TLDR
A novel finding was that reaction times increased significantly, indicating that overreaching might adversely affect speed of information processing by the brain, especially for the most difficult conditions.
Effects of androgenic-anabolic steroids on apolipoproteins and lipoprotein (a)
TLDR
Self administration of several AASs simultaneously for eight or 14 weeks produces comparable profound unfavourable effects on lipids and lipoproteins, leading to an increased atherogenic lipid profile, despite a beneficial effect on Lp(a) concentration.
