Objectives: This study aimed to determine the effect of selective (bisoprolol-5 mg) and non-selective (propranolol-40 mg) beta-blockers on archery performance, body sway and aiming behaviour.

Methods: Fifteen male archers participated in a randomised, double-blind, placebo-controlled, cross-over study and competed four times (control, placebo, selective (bisoprolol) and non-selective (propranolol) beta-blocker trials). Mechanical data related to the changes in the centre of pressure during body sway and aim point fluctuation and when shooting was collected.

This study was undertaken to investigate the relationship between blood lactate concentration ([La]) and heart rate (HR) values obtained during treadmill and field tests at fixed velocities with respect to interchangeability of results to be used in exercise prescription. A total of 22 male soccer players participated in the study. Each player performed exercise tests on a motorized treadmill and in the field with 3-min runs and 30 s allowed for blood sampling.

The aim of this study was to investigate the energy expenditure of walking with different aids in patients with spinal cord injury (SCI) and to compare the results with normal able-bodied control subjects. The tests were performed on a 20 m indoor path in a comprehensive rehabilitation clinic of a university hospital. Nine male patients with incomplete SCI at various levels from C6 to L2 and nine age- and gender-matched normal able-bodied subjects were enrolled in the study.
