conclusions acute l-carnitine supplementation possibly affects exercise performance and triglycerides in athletes rather than sedentary men. objectives this study aimed to investigate the acute effects of l-carnitine supplementation on aerobic metabolic efficiency and lipid profiles in sedentary and athletic men. methods fifteen sedentary (20.4 ± 1.5 years) and 15 athletic (21.5 ± 2.4 years) me...

The training regimens of modern-day athletes have evolved from the sole emphasis on a single fitness component (e.g., endurance athlete or resistance/strength athlete) to an integrative, multimode approach encompassing all four of the major fitness components: resistance (R), interval sprints (I), stretching (S), and endurance (E) training. Athletes rarely, if ever, focus their training on only...

Implications for sports performance and athletic injury occurrence have been forcefully insinuated by proponents of a biorhythm theory based on date of birth. The theory postulates that variations in human abilities are governed by three consistently recurring cycles of 23, 28 and 33 day lengths. This study assessed the validity of biorhythms by analysing best performances in 610 top ranked Eur...

BACKGROUND There are controversial data about the relation between foot morphology and athletic injuries of the lower extremity. Studies in soldiers have shown some relationship, whereas those involving athletes have not shown any significant relationship. The reason for these differences is not clear. OBJECTIVE To determine the effect of various sports on sole arch indices (AIs). METHOD A ...

Cross-sectional studies in athletes suggest that endurance training augments cardiovascular structure and function with apparently different phenotypes in athletic males and females. It is unclear whether the longitudinal response to endurance training leads to similar cardiovascular adaptations between sexes. We sought to determine whether males and females demonstrate similar cardiovascular a...

BACKGROUND It has been suggested that gender differences in the performance of athletic maneuvers is a contributory factor with respect to the disproportionate incidence of non-contact anterior cruciate ligament injury in female athletes. The purpose of this study was to evaluate gender differences in knee joint kinematics, kinetics and muscle activation during a side-step cutting. METHODS Th...
