Falls occurring during activities of daily living pose a major threat and are the third most common cause of death in seniors. In clinical evaluations, mostly single tests are used to assess the risk of fall. However, a complex set of tests would lead to a more comprehensive assessment of the risk of falls. The purpose of this study was to develop...

This study describes a beta version of a mobile application (app) that focuses on preventing chronic fatigue in Czech youth athletes.

This study aimed to analyse the kinematic differences in gait between three groups of toddlers who differed in their weeks of independent walking (IW) experience, but not in anthropometrical characteristics, to determine the relationship between walking experience without the side effect of morphological differences on gait parameters. Twenty-six t...

Polyphenols, secondary metabolites of plants, exhibit different anti-cancer and cytoprotective properties such as anti-radical, anti-angiogenic, anti-inflammation, or cardioprotective. Some of these activities could be linked to modulation of miRNAs expression. MiRNAs play an important role in posttranscriptional regulation of their target genes th...

Introduction: Due to an international trend of the aging population, we see increased attention paid to studies dealing with the factors that have a positive or negative impact on successful aging. As we know, a higher level of physical activity and thus increased physical fitness significantly affect the quality of aging. One of the major problems...

During pregnancy, an array of changes occurs in women body to enable the growth and development of the future baby and the consequent delivery. These changes are reflected in the range of motion of trunk, pelvis, lower limbs and other body segments, affect the locomotion and some of these changes may persist to the postpartum period. The aim of thi...

Not all the journals included in credible indices meet the ethical rules of COPE, DOAJ, OASPA, and WAME, and there may also be trustworthy journals excluded from these indices, which means they cannot be used as whitelists for trustworthy journals. Equally, the many methods suggested to determine trustworthiness are not reliable because they includ...

Based on the research review, fascia-oriented training may positively influence sports performance. Its component focused on the “catapult” mechanism can increase the capability of the connective tissue to store and release kinetic energy, which is involved in various movement actions, activities and skills including the jumping skills in volleybal...

Purpose: Many high performance and especially top athletes are still at risk or suffer from total fatigue. Therefore, sports science seeks to develop an objective, sensitive and reliable method of early diagnosis of this fatigue (e.g. heart rate variability – HRV as a modern ob-jective method). The aim of the study was to evaluate whether the HRV m...

Introduction: The police forces performance is demanding on well-timed and quick reaction. Single reaction time and choice reaction time are crucial when the jeopardy appears. Performing under stress in life-threatening situations needs a good level of stress tolerance. In our study, we used two non-specific, and two specific (shooting) tests to an...

Demographic change in a lot of countries produced an increase in the proportion of older adults in society, resulting in specific healthcare challenges.

This fact consequently affects the extent of self-sufficiency and...

The number of the elderly is growing dramatically, the average life expectancy is growing too, and we see natality decreasing at the same time. There is a close connection between life expectancy and quality of life. Due to an international trend of aging population we see an increased atten-tion paid to studies dealing with the factors that have p...

Mental and moral maturity, growth, appearance, physical skills are nowadays more and more often used as reference points of our identity and emphasized in adolescence (Harter, 1999). Development of physical self-concept’s domains (e. g. appearance, self-esteem, physical competences, etc) has been a major concern among physical activity researchers...
