Physiological correlates of skating performance in women's and men's ice hockey.

The purpose of the current investigation was to identify relationships between physiological off-ice tests and on-ice performance in female and male ice hockey players on a comparable competitive level. Eleven women, 24 ± 3.0 years, and 10 male ice hockey players, 23 ± 2.

Increased cortisol responsivity to adrenocorticotropic hormone and low plasma levels of interleukin-1 receptor antagonist in women with functional hypothalamic amenorrhea.

Objective: To assess the hypothalamic-pituitary-adrenal (HPA) axis at all levels, to determine the origin of the previously reported hypercortisolism in patients with functional hypothalamic amenorrhea. A secondary aim was to evaluate factors outside the central nervous system which are known to affect the HPA axis, i.e.

Increased bone turnover as reflected by biochemical markers in patients with potentially unstable fixation of the tibial component.

Introduction: Whether biochemical markers of bone metabolism can be used in assessing the conditions of implant fixation is unknown. In this study, the serum levels of three bone markers were measured prospectively in patients undergoing total knee arthroplasty (TKA) to determine if patients with different fixation conditions of the tibial component showed any differences in the levels of the markers.

Materials And Methods: The fixation of the tibial component in 40 knees (40 patients, 14 male and 26 female, average age 71 years) was assessed by radiostereometric analysis (RSA), and based upon the pattern of migration, implants with stable fixation ( n=25) and potentially unstable fixation ( n=15) were identified.

High intratendinous lactate levels in painful chronic Achilles tendinosis. An investigation using microdialysis technique.

In this investigation the microdialysis technique was used to study the concentrations of lactate in Achilles tendons with painful chronic tendinosis and in normal pain-free tendons. In four patients (mean age 40.7 years) with a painful thickening localized at the 2-6 cm level in the Achilles tendon (chronic Achilles tendinosis) and in five controls (mean age 37.
