The effects of active vs. passive recovery on riding performance during a simulated motocross race
2021
Aims: Motocross consists of two races of 30 min with a break in between. Recovery between races is paramount to performance, this study aimed to compare the effects of active and passive recovery between motocross races on riding performance. Methods: Thirteen elite and non-elite racers performed two races of 30 min with 1 h break, twice with two-week interval. Between the races active (20 min ergometer cycling at 60% of HRmax) or passive recovery (no activity) were executed in a randomized order. Lap times, heart rate during riding, blood lactate, reaction time, handgrip strength, upper back pull strength, counter movement jump height, and medicine ball throw distance were measured before …
Home is the new gym: exergame as a potential tool to maintain adequate fitness levels also during quarantine
2020
Purpose With the coronavirus outbreak, the preventive measures include staying at home and isolation, increasing sedentary behaviours and risk for worsening of chronic diseases To explore alternative forms of home-based physical activity, the study aim was to evaluate physiological (heart rate [HR], respiratory exchange ratio [RER], oxygen consumption [ O2], energy expenditure [EE], metabolic equivalent task [MET]) and psychological (session rating of perceived exertion [sRPE], enjoyment) parameters of real (Zumba® class [ZC]) and exergame (Zumba® Fitness Rush [ZFR]) activities in relation to sex Methods Overall, 12 female (age: 24 7 ± 0 9 years) and 8 male (age: 25 3 ± 2 1 years) college s…
Relationships between Heart Rate Variability, Sleep Duration, Cortisol and Physical Training in Young Athletes.
2021
The aims of the current study were to examine the relationships between heart rate variability (HRV), salivary cortisol, sleep duration and training in young athletes. Eight athletes (16 ± 1 years) were monitored for 7 weeks during training and competition seasons. Subjects were training for endurance-based winter sports (cross-country skiing and biathlon). Training was divided into two zones (K1, easy training and K2, hard training). Heart rate and blood lactate during submaximal running tests (SRT), as well as cortisol, sleep duration and nocturnal HRV (RMSSD), were determined every other week. HRV and cortisol levels were correlated throughout the 7-week period (r = -0.552, P = 0.01), wi…
Factores de rendimiento en el desplazamiento del tenista influenciados por el calzado. (Performance factors on tennis player displacements influenced…
2009
Los desplazamientos laterales son de gran importancia en el tenis. Sin embargo, no ha sido publicado ningun estudio sobre el efecto del calzado sobre el rendimiento en este tipo de movimientos. En el estudio participaron 5 jugadores habituales de tenis y se analizaron 10 calzados comerciales de tenis. El movimiento estudiado consistio en un desplazamiento lateral con parada y cambio de sentido, registrandose las fuerzas mediante una plataforma dinamometrica Dinascan-IBV y grabandose el movimiento con dos camaras de video S-VHS Panasonic WV-BL600. Los resultados de los ANOVAs realizados mostraron que algunas de las variables analizadas eran dependientes del calzado (p < 0.05). De estas, dest…
Monitoring stress and recovery states: Structural and external stages of the short version of the RESTQ sport in elite swimmers before championships
2016
Background: Psychological stress and recovery monitoring is a key issue for increasing athletes' health, well-being, and performance. This multi-study report examined changes and the dose–response relationships between recovery–stress psychological states, training load (TL), heart rate (HR), heart rate recovery (HRR), and heart rate variability (HRV) while providing evidence for the factorial validity of a short French version of the Recovery–Stress Questionnaire for Athletes (RESTQ-36-R-Sport). Methods: Four hundred and seventy-three university athletes (Study 1), 72 full expert swimmers (Study 2), and 11 national to international swimmers (Study 3) participated in the study. Data were an…
Enhanced inhibitory control during re-engagement processing in badminton athletes : An event-related potential study
2019
Highlights • Reaction time and event-related potentials of inhibitory control were compared in badminton experts and nonathletes. • Badminton experts showed enhanced inhibitory control and more efficient neural mechanisms. • Badminton experts performed better inhibitory control processing in re-engagement. • The re-engagement processing better demonstrated altered brain activity in badminton experts.
Predictors of increase in physical activity during a 6-month follow-up period among overweight and physically inactive healthy young adults
2015
Abstract Background/Objective The beneficial effects of physical activity (PA) are well known, but it remains challenging to increase PA among physically inactive and overweight young individuals. The present study aimed to examine how selected psychological and physical characteristics assessed at baseline predict the increase in total PA over a 6-month follow-up among 51 physically inactive and overweight adults (20 women, 31 men; age 26–40 years) who participated in a lifestyle counselling study without supervised PA sessions. Methods Baseline measurements included a questionnaire assessment of sense of coherence and psychological flexibility, heart rate monitoring-based stress/recovery …
Inspiratory and Lower-Limb Strength Importance in Mountain Ultramarathon Running. Sex Differences and Relationship with Performance
2020
The study was aimed at comparing lower-limb strength and respiratory parameters between male and female athletes and their interaction with performance in a 107 km mountain ultramarathon. Forty seven runners (29 males and 18 females
Differences in the Motor Coordination Abilities Among Adolescent Gymnasts, Swimmers, and Ice Hockey Players
2017
AbstractPurpose. Motor coordination is proposed to be a relatively stable age-related construct, unlikely to be influenced by aligned experiential factors such as intensive sport-specific training. The purpose of the study is to investigate if there are differences in motor coordination abilities among young artistic gymnasts, swimmers, and ice hockey players.Methods. The participants of the study were 508 female and 258 male adolescents (age, M = 12.80, SD = 1.10) comprising artistic gymnasts (n = 463), swimmers (n = 70), and ice hockey players (n = 233). The KTK-test protocol was used to analyse their gross motor coordination abilities.Results. The results of the study demonstrated that g…
Somatotypes and handgrip strength analysis of elite Serbian sambo athletes
2021
The aim of this study was to establish whether there are differences between weight categories in different anthropometric measurements and handgrip strength between elite Serbian male and female sambo athletes divided into weight categories. A total of 70 elite Serbian sambo athletes participated in the study, who were participants of the World Cadet Sambo Championship held in Novi Sad. Athletes are classified into categories according to gender and official weight categories. Using anthropometry, we calculated somatotypes and hand-grip strength. For statistical analysis, we used a one-way analysis of variance and Tukey’s post hoc tests to compare group differences by weight categories. So…
