Modulation of Heart Rate by Acute or Chronic Aerobic Exercise. Potential Effects on Blood Pressure Control.
2017
It was initially assumed that heart rate and arterial blood pressure were modulated by normal respiration and muscle contraction. The arterial baroreflex, an inverse relationship between blood pressure and heart rate, was later reported. Nonetheless, it was then assumed that those responses involved vagal modulation. We summarize available evidence on the modulation of heart rate by acute or chronic aerobic exercise as well as its potential implications on blood pressure (BP) control. Numerous studies have tried to clarify whether aerobic exercise modifies neurally-mediated vasoconstriction, but they report contradictory results. In view of these incongruities, the aim of this narrative rev…
Alpha-amylase serum levels in professional soccer players are not related with physical fitness.
2017
Backgorund Recent evidence has showed that serum or salivary values of α-amylase predict endurance running performance. In this study we investigate whether serum α-amylase concentration may be associated with training status during a competitive season and after a detraining period in professional soccer players. Methods The study population consisted in 15 male professional soccer players from an Italian major league team (age [mean±SD] 27±5 years, weight 76.9±4.1 kg, height 1.82±0.05 m). Serum α-amylase levels were measured 3 times during the last part of a competitive season (January, March and May) and just before preseason training (July). Results Metabolic and cardiovascular fitness …
Normative data of BMI and physical fitness in a Norwegian sample of early adolescents.
2013
Aim: The purpose of the present study was to 1) provide normative data quantifying the physical fitness level and body mass index of 13–15-year-old Norwegian adolescents using a multi-component fitness assessment, and 2) compare the physical fitness of Norwegian teenagers with available European and International fitness data. Methods: 1059 adolescents (529 males, 530 females) from 12 public schools in Kristiansand were invited to testing at age 13, 14, and 15 years (Grades 8–10). Test participation was 75%–80%. The participants performed objectively anthropometrical measures (height and weight) and six field-based physical fitness tests. Results and Conclusions: As expected, sex differenc…
Cardiovascular fitness in youth: association with obesity and metabolic abnormalities
2014
[ES] Las terapias que se implantan actualmente para la obesidad se centran en los aspectos nutricionales y sobre la actividad física. Con el fin de hacer que la actividad física sea una terapia positiva en vez de un desencadenador de discapacidades, es relevante evaluar de forma precisa el entrenamiento cardiovascular. Objetivo: evaluar el entrenamiento cardiovascular midiendo el consumo máximo de oxígeno y evaluar su relación con los parámetros cardiometabólicos clásicos. Métodos: se aplicó el protocolo modificado de Balke a 126 individuos caucásicos (60 % de varones), con edades entre 9 y 16 años, que se sometieron a una evaluación de obesidad. El grupo de no obesos consistía de individuo…
Associations of commuting to school and work with demographic variables and with weight status in eight European countries: The ENERGY-cross sectiona…
2017
This study aims to assess the prevalence of different modes of commuting to school and work for 10–12 year-olds and their parents; to assess the associations with demographic variables (country, sex, parental education and ethnicity) and with weight status in eight European countries. As part of the ENERGY project a cross-sectional survey was conducted in 2010 in which modes of commuting and socio-demographic variables for children (N = 7903) and one of their parents (n = 6455) were measured by questionnaires. Children's weight and height were objectively measured; parents self-reported their weight and height. Logistic multilevel regression analyses assessed the associations between mode o…
Exercising recommendations for paroxysmal AF in young and middle-aged athletes (PAFIYAMA) syndrome.
2017
We have recently described a new syndrome: strenuous endurance exercise-related atrial fibrillation (AF) under the acronym of ‘paroxysmal AF in young and middle-aged athletes’ (‘PAFIYAMA’). Provided that other risk factors for AF and underlying conditions have been excluded (1), the diagnostic criteria for this syndrome entail a number of conditions, classified as major and minor. An enhanced risk of AF has been clearly documented in endurance athletes (top-class, elite and recreational) (2-5), and such risk typically ranges between 1.2- to 15-fold compared to the general, sedentary population (the better cardiovascular fitness, the higher incidence of AF) (6-11). Anecdotally, the last auth…
Assessment of autonomic function as marker of training status: the role of heart rate recovery after exercise
2014
Heart rate recovery (HRR) is the rate at which the heart rate returns to baseline after a period of exercise. HRR is a marker of autonomic function and a predictor of cardiovascular fitness in healthy subjects and in those with cardiovascular diseases. Moreover, HRR has been proposed as a marker of training status in athletes. Our aim was to perform a review of studies that evaluated HRR after exercise in trained and untrained healthy subjects and assessed its relationship with training status. Several studies suggest that the assessing of HRR after exercise may be useful to distinguish trained from untrained individuals and to establish an athlete’s state of training. However, standardizat…
Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä : kahden kävelytestin vertaaminen
2015
Eveliina Keinonen (2015). Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä: Kahden kävelytestin vertaaminen. Liikuntakasvatuksen laitos, Jyväskylän yli-opisto, liikuntapedagogiikan pro gradu –tutkielma, 66 s., 3 liitettä. Tutkimuksen tavoitteena oli tarkastella keski-ikäisten kehitysvammaisten naisten ja miesten kestävyyskunnon tasoa vammattomaan väestöön sekä Suomessa yleisesti käytössä oleviin terveysliikunnan suosituksiin verrattuna. Tarkastelun kohteena oli myös kehitysvammaisten kestävyyskunnossa esiintyvät muutokset seitsemän vuoden aikana. Lisäksi tutkimus pyrki selvittämään onko samanaikaisesti suoritettujen UKK-instituutin 2 kilometrin kävelytestin ja Rockport…
Development of accelerometer-based light to vigorous physical activity in fitness profiles of school-aged children.
2021
This study examined the developmental trajectories of light (LPA) and moderate-to-vigorous physical activity (MVPA) in fitness profiles derived from motor competence, perceived motor competence, health-related fitness, and MVPA behaviour. Locomotor, stability, and object-control skills, muscular and cardiovascular fitness, and physical activity were assessed in 510 (girls 285, boys 225) Finnish school-aged children (Mage = 11.26 ± .33 years) over three years. Physical activity was measured using hip-mounted accelerometers. Fitness profiles were identified using latent profile analysis and the development of physical activity levels across four assessments was analysed with latent growth cur…
Sport participation and vigilance in children: Influence of different sport expertise
2018
PURPOSE: The present study aimed to investigate the relationship between different types of sport expertise (externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. METHODS: Three groups of children (11.0 ± 0.2 years) differentiated in terms of their regular sport participation (football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their v…
