Comparison of Lateral Abdominal Muscle Thickness and Cross Sectional Area of Multifidus in Adolescent Soccer Players with and without Low Back Pain: A Case Control Study.

Background: Low back pain (LBP) is a common complaint amongst adolescent athletes. While different studies have shown association between LBP and trunk muscle thickness in the general population, few articles have studied it in adolescent athletes.

Objectives: The aim of this study is to compare lateral abdominal muscle thickness and function, and cross sectional area (CSA) of lumbar multifidus (LM) in adolescent soccer players with and without LBP.

A 90 minute soccer match decreases triglyceride and low density lipoprotein but not high-density lipoprotein and cholesterol levels.

Background: The association between the lipid profiles level and the incidence and severity of coronary heart disease (CHD) is very pronounced in epidemiological studies, and an inverse relation between physical fitness and the incidence of coronary heart disease has been observed in many studies. The aim of this study was to investigate the impact of a soccer match on lipid parameters of professional soccer players.

Methods: Twenty two professional soccer players participated in the study.

The effects of arm cranking exercise and training on platelet aggregation in male spinal cord individuals.

Platelet aggregation at rest and in responses to exercise and training were compared between spinal cord injured (SCI) individuals (N=5) and able-bodied subjects (N=7). All participants performed arm cranking exercise at 60-65% VO(2peak) for 30 min. Venous blood samples were obtained before and after sub-maximal exercise and measured for platelet aggregation using ADP and collagen.
