Small-sided games (SSGs) are spontaneous forms of specific training where exercise intensity can be manipulated by modifying external factors. To ensure suitable usage of small-sided games in practice, we have to know which variables can influence internal responses and external loads. The aim of the present study was to determine the influence of presence of a goalkeeper and the pitch size on ...

OBJECTIVE Our purpose was to assess the diagnostic characteristics of the exercise test in patients who fail to reach conventional target heart rates and in patients on beta-blockers. BACKGROUND Exercise test results are often considered "inadequate" or "nondiagnostic" in patients taking beta-blockers and in patients who do not achieve 85% of their age-predicted maximal heart rate. METHODS ...

objectives: wheelchairs are the prime mobility aid of persons with spinal cord injuries. manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. the main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

background: this study was conducted to evaluate variations in heart rate and to determine the occurrence of oculocardiac reflex (ocr) during laser in situ keratomileusis (lasik). methods: this descriptive, prospective study was designed to observe the effect of suction ring and ablation stages during lasik procedure on the heart rate. the ecg was taken before and during lasik operation on the ...
