Does Intense Endurance Workout Have an Impact on Serum Levels of Sex Hormones in Males?

The benefits of physical activity and sports are widely known and proved to be crucial for overall health and well-being. In this research, the authors decided to measure the impact of endurance training in a professional male rowing team on the serum concentration levels of testosterone, estradiol, sex hormone binding globulin (SHBG) and nitric oxide (NO) and apolipoprotein A1 (Apo-A1). Proper levels of the serum concentration are necessary in order to maintain physical effectiveness.

Multiannual, Intensive Strength-Endurance Training Modulates the Activity of the Cardiovascular and Autonomic Nervous System among Rowers of the International Level.

Introduction: Professional athlete training is significantly different from recreational physical activity, and sustained, repetitive exposure to over-strenuous and intensive training may result in critical changes of most systems and organs in a sportsman's body.

Aim: The assessment of the influence of multiannual strength-endurance training on the autonomic nervous system (ANS) and cardiovascular system (CVS) among the rowers of Polish national team.

Materials And Methods: 20 rowers, aged 20-30, seniors of Polish national team were qualified into the study.

Long-term high intensity sport practice modulates adaptative changes in athletes' heart and in the autonomic nervous system profile.

Background: The purpose of this study was to compare cardiovascular and autonomic adaptation changes in athletes exposed to high intensity and uninterrupted training for extended periods of time.

Methods: We assessed hemodynamic profile and cardiac function in 22 international master-level athletes free of cardiovascular disease who experienced particularly intensive and uninterrupted training over an 8- to 21-year-period.

Results: One-way ANOVA revealed that in athletes, extreme and uninterrupted strength and endurance training over long periods of time (up to 21 years) causes an increase in resting heart rate (50.

The influence of active exercise in low positions on the functional condition of the lumbar-sacral segment in patients with discopathy.

Background: Pain in the lower segments of the spine is among the most frequent symptoms in industrialized countries. Injuries to intervertebral discs are the cause of this kind of discomfort in 90% of cases. The factors promoting the disease are: physical activity limitation, prolonged sitting position, overweight and bad movement stereotypes.

Discopathy of the lumbar-sacral segment and its influence on sexual dysfunction.

Background: Intervertebral disc disease is a widespread medical and social problem. Degeneration of intervertebral discs can lead to disc disease, commonly known as discopathy. One of the consequences of discopathy is pressure on the spinal cord or nerve roots that supply the genitals and sexual centers located in the core.
