- Changes in glutamine and glutamate concentrations for tracking training toleranceD J Smith
Human Performance Laboratory, Faculty of Kinesiology, The University of Calgary and The National Sports Centre Calgary, Alberta, Canada
Med Sci Sports Exerc 32:684-9. 2000..The purpose was to monitor high-performance athletes throughout training macrocycles and competitions and examine the changes in plasma glutamine (Gm) and glutamate (Ga) concentrations in order to develop a model of tolerance to training...
- A framework for understanding the training process leading to elite performanceDavid J Smith
Human Performance Laboratory, Faculty of Kinesiology, University of Calgary, Alberta, Canada T2N 2N4
Sports Med 33:1103-26. 2003..Finally, at competition time, optimal performance requires a healthy body, and integration of not only the physiological elements but also the psychological, technical and tactical components...
- Performance evaluation of swimmers: scientific toolsDavid J Smith
Human Performance Laboratory, Faculty of Kinesiology, University of Calgary, Calgary, Alberta, Canada

- Vibration training: an overview of the area, training consequences, and future considerationsMatthew J Jordan
Canadian Sport Centre Calgary, University of Calgary, Calgary, Alberta T2N 1N4, Canada
J Strength Cond Res 19:459-66. 2005..Future research should be done with the aim of understanding the biological effects of vibration on muscle performance and also the effects of different vibration protocols on muscle performance...
- Erythropoietin does not demonstrate circadian rhythm in healthy menD Roberts
Faculty of Kinesiology, University of Calgary, Alberta, Canada
J Appl Physiol 80:847-51. 1996..5 +/- 5.3 (SD) U/l. No significant circadian variation in serum Epo concentrations was observed in either group or when both groups were combined; however, a measure of individual variance was observed (mean deviation = 0.8 +/- 0.4 U/l)...
- Training principles and issues for ultra-endurance athletesCalvin Zaryski
Human Performance Laboratory, Faculty of Kinesiology, University of Calgary, 2500 University Drive NW, Calgary, AB T2N 2N4, Canada
Curr Sports Med Rep 4:165-70. 2005..Furthermore, the treatment of soft tissue after training or racing is necessary to control inflammation...
- Diurnal normobaric moderate hypoxia raises serum erythropoietin concentration but does not stimulate accelerated erythrocyte productionSpencer R McLean
Human Performance Laboratory, Faculty of Medicine, Health Sciences Centre, University of Calgary, 3330 Hospital Drive NW, Calgary, Alberta T2N 4N1, Canada
Eur J Appl Physiol 96:651-8. 2006..The results suggest that the degree of hypoxia was sufficient to stimulate increased erythropoietin production and release. However, the duration of hypoxic exposure was insufficient to propagate the erythropoietic cascade...
- Plasma-volume contraction and exercise-induced hypoxaemia modulate erythropoietin production in healthy humansD Roberts
Human Performance Laboratory, Faculty of Kinesiology, University of Calgary, 2500 University Drive N W, Calgary, Alberta, Canada T2N 1N4
Clin Sci (Lond) 98:39-45. 2000..The paradoxical responses of the increased haematocrit and the increase in Epo in subjects undergoing plasmapheresis suggests that plasma volume may also modulate the production of Epo...
- Tissue residues and urinary excretion of zilpaterol in sheep treated for 10 days with dietary zilpaterolWeilin L Shelver
Biosciences Research Laboratory, Agricultural Research Service, U S Department of Agriculture, 1605 Albrecht Boulevard, Fargo, North Dakota 58105, USA
J Agric Food Chem 54:4155-61. 2006..Because of its simplicity, ELISA is a convenient assay for determining zilpaterol levels in urine giving similar results to HPLC-fluorescence and LC-MS/MS-ES without requiring the extensive cleanup of the latter methods...
