The aim of the study was to evaluate cardiac autonomic activity in free diving (FD) athletes. Thirteen Greek male divers (group I, aged 33.4 ± 6.3 years, 6.6 4.5 years training experience) volunteered participate while 13 age-matched sedentary subjects served as control group II). All were submitted ambulatory 24-h ECG recording for heart rate variability (HRV) analysis on a day regular activities with no exercise or training. results showed that I had significantly lower minimum and mean by...

Aim The investigation of the pathophysiological determinants cardiac changes following ultra-long duration exercise. Methods Twenty-seven runners who finished a 246 km running race were examined both before and after finish race. Examinations included echocardiography measurement body weight blood biochemical parameters. Results Exercise increased left ventricular end-diastolic interventricular septum thickness (LVIVSd) ( p < 0.001) posterior wall (LVPWTd) = right area 0.005), while...

The purpose of this study was to assess the heart rate variability triangular index (HRVI) in elite track and field athletes. Sixty healthy males (mean aged 22.1 +/- 3.5 years) -15 long distance runners (group A), 15 speed (Group B), throwers C) non-trained subjects D) were submitted spiroergometric test, m-mode echocardiography 24-h ambulatory ECG monitoring. HRVI, mean rate, interval between two consecutive R waves QRS complexes (R-R interval) standard deviation R-R (SDRR) assessed through...

J Strength Cond Res 33(10): 2629-2634, 2019-The aim this study was to examine the correlation between muscle fiber type elite young players different age groups same team. Twenty-eight participated (group U15, n = 8; group U13, 9; U11, 11). Anthropometric assessments, acceleration (10 m), Bangsbo modified test (30 m) were...

Shoulder pain is a common syndrome in swimming and affects large number of competitive swimmers. The purpose the study was to investigate relationship between shoulder girdle endurance trunk muscles young A total 24 boys 22 girls, aged 13 18 years, participated study. measurements included completion questionnaire (Shoulder Pain Disability Index, SPADI) field test (McGill’s Torso Muscular Endurance Test). SPADI score correlated weakly negatively with time back both sexes (r2 = 0.10, p...

BackgroundCardiac disorders constitute the most common causes of sudden cardiac death (SCD) and mitral valve prolapse (MVP) is one structural in young populations. The aim this study was to evaluate some reliable non-invasive electrophysiological variables SCD athletes with mild or moderate MVP compare them their cardiorespiratory adaptations. DesignThe population comprised 40 amateur male soccer players, who were equally subdivided into those (group A, aged 20.4 ± 4.5 years) without B, 18.4...

The aim of this study was to examine the deltoid muscle properties dominant and non-dominant arm Greek professional male tennis players. Eight players (mean age 22.0 years, s = 3.2) were subjected biopsy both arms. Adenosine triphosphate (ATPase) histochemistry myosin heavy chain (MHC) composition performed on samples with homogenate electrophoresis. No significant differences observed in percentage types I, IIa, IIab, IIb fibres between muscles two Types IIx did not differ significantly for...

Background: Traditionally, stretching protocols are basic components of warm-up aiming to improve performance and reduce injuries. However, the literature suggests that different during may have diverse effects on performance. Objective: The purpose this study was compare acute three force sense, dynamic flexibility, reaction time movement time. Methods: included twenty-five participants who were TaeKwonDo young male players (age = 11.78 ± 1.66 years.). All performed one following days: (a)...

The purpose of this study was to examine the effects submaximal sustained contractions on fatigue and recovery properties in untrained prepubescent boys (n = 14) men 14). All participants performed, random order, an isometric plantar flexion at 20% 60% their maximal voluntary contraction (MVC) until exhaustion (20% , respectively). During both protocols, surface electromyogram (sEMG) soleus tibialis anterior muscles recorded. Before after protocol, MVCs blood lactate concentration were...

Summary Background Structural and functional arterial adaptations with regard to the type level of training in young athletes are understudied. Our research aimed at evaluating them two types exercise (dynamic static) levels engagement (high recreational). Methods A total 76 volunteers formed five groups. Group included 17 high‐level dynamic sports 30·9 ± 6·4 years old, group B 14 recreational ones aged 28·7 6·2 years, C 15 static 26·4 3·9 old D 16 ones, 25·8 4·8 years. Fourteen sedentary...

Although previous studies suggest that prolonged intense exercise such as marathon running transitorily alters cardiac function, there is little information regarding ultramarathon races. Aim of this study was to investigate the acute impact ultra-endurance (UEE) on heart, applying advanced strain imaging. Echocardiographic assessment performed day before and at finish line "Spartathlon": A 246 Km ultra-marathon race. 2D speckle-tracking echocardiography in all four chambers, evaluating...
