Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts
2015
Savolainen, S. 2015. Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts, 64p. University of Jyväskylä. Department of Biology of Physical Activity. Science of Sports Coaching and Fitness Testing. The aim of this study was to examine physiological consequences on 8-day strenuous military field exercise. 26 men (20 ± 1 yrs, 53,7 ± 4,5ml/kg/min, 178,4 ± 7,2cm, 71,2 ± 7,2kg) in the end of their military service participated in the study. The research data was collected in five testing day (pre1, pre2, middle, post and follow-up); body composition, physical performance and basal blood levels were measured. The c…

Motives for competitive sports participation in masters track and field athletes : Impact of sociodemographic factors and competitive background
2022
Objectives Masters athletes due to their lifelong engagement in sport represent a unique group to study motivation for regular physical activity, but there is less scientific data on the sport motives in masters athletes. Therefore, the aim of this study was to evaluate the association of age, sex, education, nationality, competitive background and training amount with sport motives of masters track and field athletes. Methods 811 (254 women) athletes aged 35–89 years participated in European Veterans Athletics Championships in the year of 2000. Sport motives were assessed with a questionnaire and categorized into1) well-being, 2) competitive and performance 3) health and fitness motives. R…
Effects of Task-Specific and Strength Training on Simulated Military Task Performance in Soldiers.
2020
A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…
Monitoring Training and Recovery during a Period of Increased Intensity or Volume in Recreational Endurance Athletes
2021
The purpose of the study was to examine the effects of progressively increased training intensity or volume on the nocturnal heart rate (HR) and heart rate variability (HRV), countermovement jump, perceived recovery, and heart rate-running speed index (HR-RS index). Another aim was to analyze how observed patterns during the training period in these monitoring variables were associated with the changes in endurance performance. Thirty recreationally trained participants performed a 10-week control period of regular training and a 10-week training period of either increased training intensity (INT, n = 13) or volume (VOL, n = 17). Changes in endurance performance were assessed by an incremen…
Evolución de la incidencia y de la supervivencia del carcinoma broncogénico en la provincia de Castellón en el periodo de tiempo comprendido entre 20…
2022
El carcinoma broncogénico (CB) es el más frecuente a nivel mundial y el más letal en ambos sexos. La incidencia del CB varía no sólo entre países sino también entre distintas zonas de un mismo país. Dado que la OMS recomienda disponer de estrategias de lucha contra el cáncer, creemos que analizar su situación en una zona geográfica dada puede contribuir a establecer una correcta planificación sanitaria. En consecuencia, hemos planteado el presente trabajo con los principales objetivos de: 1.- Conocer las principales características anatomopatológicas, clínicas, y epidemiológicas del CB en la provincia de Castellón entre 2004 y 2017. 2.- Analizar la evolución en este tiempo de las tasas de i…
La quimioembolización transarterial en el tratamiento del carcinoma hepatocelular en estadio intermedio. Estudio de los factores predictivos de super…
2014
La QETA es actualmente el tratamiento de elección del CHC en estadio intermedio de la BCLC. A pesar de ser la terapia más utilizada, existen múltiples aspectos por dilucidar, principalmente la identificación de los mejores candidatos dentro del amplio y heterogéneo grupo de pacientes que componen el estadio intermedio. Los objetivos primarios de este estudio han sido establecer la supervivencia global y actuarial asociada al tratamiento con QETA e identificar los factores predictivos de supervivencia mientras que como objetivos secundarios se han analizado la respuesta tumoral completa y objetiva, la supervivencia libre de enfermedad y la seguridad de la terapia. Entre mayo de 2002 y junio …
Suplementy diety dla sportowców w aspekcie przepisów antydopingowych
2022
Motywacja w zakresie stosowania suplementów diety w sporcie jest duża i silnie skorelowana z potrzebą osiągania coraz lepszych wyników przez konsumenta. Dane pochodzące z Centrum Badań Opinii Społecznej wskazują, że dziewięciu na dziesięciu dorosłych Polaków stosuje suplementację, a sportowcy wielokrotnie sięgają po kilka suplementów jednocześnie. Korzystanie z suplementów zależy przede wszystkim od rodzaju uprawianej dyscypliny sportowej i wzrasta wraz z intensywnością treningu oraz wiekiem respondentów. Opublikowane dane sugerują również, że sportowcy są skłonni przyjmować suplementy bez gromadzenia wiarygodnych informacji o zawartych w nich substancjach aktywnych. Dlatego w historii spor…
An Integrated Approach to Skeletal Muscle Health in Aging
2023
A decline in muscle mass and function represents one of the most problematic changes associated with aging, and has dramatic effects on autonomy and quality of life. Several factors contribute to the inexorable process of sarcopenia, such as mitochondrial and autophagy dysfunction, and the lack of regeneration capacity of satellite cells. The physiologic decline in muscle mass and in motoneuron functionality associated with aging is exacerbated by the sedentary lifestyle that accompanies elderly people. Regular physical activity is beneficial to most people, but the elderly need well-designed and carefully administered training programs that improve muscle mass and, consequently, both funct…
