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 ...

The effect of interval exercise training on the peak coital heart rate in post myocardial infarction patients was studied. Sixteen men (ages 46-54) underwent a 16-week bicycle ergometer training program 12 to 15 weeks following their first myocardial infarction. Portable ECG tape recorders were used to record the ECG during coitus twice before and twice after the training program. The maximum m...

OBJECTIVE To evaluate the ratio of peak oxygen consumption to peak heart rate (peak oxygen pulse) as a predictor of long term prognosis in chronic heart failure. PATIENTS AND SETTING 178 consecutive heart failure patients recruited to the cardiology department of a tertiary referral centre between 1986 and 1993. DESIGN Bicycle ergometry with measurement of respiratory exchange. Mean (SD) fo...

We read with great interest the article, entitled “Heart rate recovery may predict the presence of coronary artery disease” by Akyüz et al. (1) published in Anatolian J Cardiol 2014; 14: 351-6. They observed in a retrospective analysis that abnormal heart rate recovery at 1 min (HRR1) was associated with the presence of angiographically proven coronary artery disease. This study strengthens pre...

The purpose ofthe study was to asscss whcthcr the point of deilection from linearjty of heart rate (HRD) could bc uscd as an alternative method to determine the ventilatory threshold (VT) in Indian (Bengali) boys that rcprcscnts thc detcrmination of the anaerobic threshold (M), and also to standardize an cxcrcise test to be efTt]ctive in eliciting AT in Indian (Bensali) boys by using HRD.

The interrelation between the rates of the innervated recipient heart and the denervated donor heart at rest, on standing, and during the different phases of maximal exercise was studied in nine patients 1-6 months after heterotopic cardiac transplantation. The resting heart rate was significantly higher in the donor heart compared with the recipient heart. Eight of the nine recipient hearts an...

BACKGROUND The initial response of heart rate to dynamic exercise has been proposed as having prognostic value in limited studies that have used modalities other than the treadmill. Our aim was to evaluate the prognostic value of early heart rate parameters in patients referred for routine clinical treadmill testing. METHODS AND RESULTS The heart rate rise at the onset of exercise was measure...

BACKGROUND Young patients with obstructive sleep apnea syndrome (OSAS) display an attenuated heart rate recovery (HRR) during the first minute (HRR-1) and the first 2 min (HRR-2) postexercise. We sought to compare determinants of HRR-1 and HRR-2 in OSAS and to assess whether these associations depend on age. METHODS Exercise testing with measurements of HRR-1 and HRR-2 was performed in 54 pat...

BACKGROUND AND OBJECTIVES This study was aimed at assessing left ventricular torsion (LVtor) mechanics using speckle tracking echocardiography (STE), establishing normal reference values of principal LVtor parameters, and analyzing the age-related changes in normal children. SUBJECTS AND METHODS Eighty children (aged 3 months to 15 years) with normal cardiac function and rhythm were recruited...
