“…Average office systolic BP ranged from 110 ± 7 mm Hg to 134 ± 9 mm Hg, diastolic BP from 62 ± 9 mm Hg to 80 mm Hg (pooled mean values being 121.6 ± 1.3 and 72.4 ± 1.3 mm Hg, respectively). Average LVMI varied from 77 ± 13 g/m 2 to 150 ± 11 g/m 2 (pooled mean g/m 2 104 ± 8 g/m 2 ).…”

Aim Information on left atrium (LA) enlargement, as assessed by LA volume (LAV) instead of LA diameter, in the athletic population is scanty. To expand current knowledge on this issue, we performed an updated meta‐analysis of echocardiographic studies. Design The Ovid MEDLINE, PubMed, and Cochrane CENTRAL databases were searched for English language articles without time restriction up to February 2018 through focused, high sensitive search strategies. Studies were identified by crossing the following search terms: “athletes,” “physical training,” “left atrial size,” “left atrial volume,” “atrial function,” and “echocardiography.”. Results Overall, 3145 subjects (2425 elite athletes and 720 active but not trained healthy controls) were included in 16 studies. Average LAV indexed to BSA (LAVI) was 37% higher in athletes as compared to nonathletic controls (31.0 ± 1.4 mL/m2 vs 22.2 ± 0.9 mL/m2), the standard means difference (SMD) being 1.12 ± 0.13 (CI: 0.86‐1.89, P < 0.0001). SMD was higher in high‐dynamic/high‐static trained athletes (1.78 ± 0.24, CI: 1.30‐2.20, P < 0.001) than in high‐dynamic/low‐static trained athletes 1.00 ± 0.16, CI: 0.70‐1.30, P < 0.001). The statistical difference did not change after correction for publication bias and was not affected by a single study effect. Conclusions Our meta‐analysis suggests that the adaptation of LA to intensive physical training in elite athletes is characterized by a marked increase in LAVI; LA dilation is more pronounced in the subgroup of high‐dynamic/high‐static trained athletes. The functional and clinical implications related to advanced LA dilation in athletes and particularly in those engaged in high‐dynamic/high‐static disciplines deserve further investigations.

“…Based on literature sources, between 2009 and 2014, the average height of NHL Combine hockey players (n = 592) was 1.86 ± 0.05, their average body weight was 86.79 kg ± 6.36 kg, and the average the maximum oxygen consumption was: VO2max 56.6 ml/min/kg ± 4.6 ml/min/kg. (Ong, et al, 2017) According to some research groups, there are significant differences between the physiological profiles of offensive players, defensive players, and goalkeepers. Interestingly, offensive players have significantly higher aerobic abilities and lower body fat percentages than defensive players or goalkeepers.…”

Position-based anthropometric characteristics and general physiological performance of national level, U18 ice hockey players

et al. 2023

Identifying talented players requires subjective, as well as objective assessments of playing ability and performance. The assessment of anthropometric characteristics, as well as general physiological performance can be used for player selection. The primary purpose of this study was to determine whether positional profiling is possible for national level ice hockey players by examining anthropometric characteristics and physiological performance. The study involved two ice-hockey teams, U18 and U23, in total of 49 athletes (32 forwards and 17 defensemen), members of the “Székelyföldi” Ice Hockey Academy (SZJA). Data collection was conducted in May 2020, at the SZJAs Medical and Methodological Center. Body height was determined including barefoot height (± 0.1 cm) using a wall mounted stadiometer. Body weight was measured with a standard scale. A standard incremental maximal oxygen uptake test was conducted in the laboratory by means of open-circuit spirometry and computerized instrumentation (CPET Cosmed, Italy) following the Bruce protocol. With the use of the descriptive statistics, we found no differences at the anthropometric characteristics between forwards and defensemen. Regarding the physiological characteristics, some possible differences were found for maximal- and absolute oxygen uptake rate. While our results from descriptive statistics show no significant differences between the two studied ice hockey position, based on the Mann-Whitney U test, considering all parameter values, we found that there were significant differences between the two groups within this sample number.

“…In this regard, the cardiovascular system has to increase its workload compared with moderate-intensity exercise ( 13 ), which potentially leads to adverse cardiovascular system adaptations ( 14 ). A previous study showed that training for competitive ice hockey induces LV cavity dilation and increased LV mass, and the associated cardiac adaptations serve to normalize wall stress ( 15 ). However, the IVPD in the dilated LV cavity with an increased LV mass in female ice hockey athletes remains to be explored.…”

BackgroundIce hockey is a high-intensity dynamic sport for which competitive athletes train for longer than 20 hours each week for several years. The cumulative time of myocardial exposure to hemodynamic stress affects cardiac remodeling. However, the intracardiac pressure distribution of the elite ice hockey athletes' heart during adaptation to long-term training remains to be explored. This study aimed to compare the diastolic intraventricular pressure difference (IVPD) of the left ventricle (LV) between healthy volunteers and ice hockey athletes with different training times.MethodsFifty-three female ice hockey athletes (27 elite and 26 casual) and 24 healthy controls were included. The diastolic IVPD of the LV during diastole was measured by vector flow mapping. The peak amplitude of the IVPD during isovolumic relaxation (P0), diastolic rapid filling (P1), and atrial systole (P4); the difference in the peak amplitude between adjacent phases (DiffP01, DiffP14); the time interval between the peak amplitude of adjacent phases (P0P1, P1P4); and the maximum decrease rate in diastolic IVPD were calculated. Differences between groups, as well as correlations between hemodynamic parameters and training time, were analyzed.ResultsStructural parameters of the LV were significantly higher in elite athletes than in casual players and controls. No significant difference in the peak amplitude of the IVPD during the diastolic phase was found among the three groups. The analysis of covariance with heart rate as a covariate showed that P1P4 in the elite athlete and casual player groups was significantly longer than that in the healthy control group (p < 0.001 for all). An increased P1P4 was significantly associated with an increased training year (β = 4.90, p < 0.001).ConclusionsThe diastolic cardiac hemodynamics of the LV in elite female ice hockey athletes could be characterized by a prolonged diastolic IVPD, and P1P4 prolonged with an increase in the training years, reflecting a time–domain adaptation in diastolic hemodynamics after long-term training.
