Different-day and same-session combined strength and endurance training : adaptations in neuromuscular and cardiorespiratory performance, body compos…
2017
This thesis investigated 1) acute neuromuscular and hormonal responses to combined strength and endurance loadings with different orders and their long-term adaptations (women), 2) adaptations in neuromuscular, hormonal, cardiorespiratory and health variables following 24 weeks of volume-equated protocols of combined training (men and women). Subjects were assigned to one of three groups: strength and endurance training on different days (DD: men n=21, women n=18), training in the same-session with either endurance before strength (ES: men n=16, women n=15) or vice versa (SE: men n=18, women n=14). DD trained 4-6 d·wk-1 with strength and endurance on alternating days. ES and SE trained 2-3 …
Changes in nocturnal heart rate variability and endurance performance during a high-intensity or high-volume endurance training period in recreationa…
2014
It is known that endurance training affects the modulation of the autonomic nervous system and heart rate variability (HRV). As a method HRV may be a potential tool to monitor trainability and endurance training adaptation. The purpose of this study was to examine changes in nocturnal HRV indices and endurance running performance during high intensity versus high volume endurance training. In total, 28 recreational male and female endurance runners (35 ± 8 year, VO2max 50 ± 5 ml/kg/min) were matched into two training groups after the 8 week basic training period (BTP) according to HRV, endurance performance and training adaptation during BTP. During the 8 week hard training period (HTP), th…
Predicting and monitoring individual endurance training adaptation and individualizing training prescription : with endurance performance, cardiac au…
2016
Humans adapt differently to standardized endurance training programs. While some individuals may achieve huge improvements in physical fitness, other individuals may even suffer from negative adaptations. Special attention should be paid to identification of non-responders, which would enable to modify training to be more effective. Therefore, the aim of the present study was to investigate whether running performance, cardiac autonomic regulation and neuromuscular performance can be used in 1) predicting subsequent endurance training adaptations; 2) monitoring training adaptations; and 3) individualizing training prescription in recreational endurance runners. Three longitudinal training s…
The roles of linguistic confidence and integrative motivation on cross-cultural adaptation of Asian degree students Finland
2015
While cross-cultural adaptation of international students has become more and more popular topics in the field of intercultural communication, there are few studies related to students who come to non-native-English-speaking countries to study international programs. Specifically, the number of Asian students enrolling in international degree programs in Finland has been increasing recently. Besides other difficulties, language has become one of the most baffling issues in the process of both sociocultural adaptation and psychological adaptation of strangers in the host country (Maza, 1963). By narrowing the impacts of integrative motivation and linguistic confidence, they have drawn some r…
Cross-cultural adaptation and validation of the Kerlan-Jobe Orthopaedic Clinic shoulder and elbow score in Finnish-speaking overhead athletes
2022
Background The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) is developed to evaluate the shoulder and elbow function in overhead athletes. To date, the score has not been adapted into Finnish language. The aim of this study was to perform a cross-cultural adaptation of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) into Finnish language and evaluate its validity, reliability, and responsiveness in overhead athletes. Methods Forward–backward translation method was followed in the cross-cultural adaptation process. Subsequently, 114 overhead athletes (52 males, 62 females, mean age 18.1 ± 2.8 years) completed the Finnish version of KJOC score, Disabilitie…
Cultural Adaptation of the Modified Version of the Conflicts Tactics Scale (M-CTS) in Mexican Adolescents
2019
Several scales are used in Dating Violence studies assuming cross-cultural invariance and equivalence of the measures without making the proper validation in the intended populations. This study focuses on the importance of adapting existing dating violence psychological instruments (as the widely recognized Modified Version of the Conflict Tactics Scale, M-CTS) in diverse adolescent populations adjusting to international validation procedures that ensure the cultural fit of the instrument and the measurement invariance of the construct. We sought to adapt the M-CTS in Mexican adolescents (N = 1861; 57.5% woman) following the ITC Guidelines for Translating and Adapting Test. We made an anal…
Gratitude Questionnaire–20 Items (G20): A Cross-Cultural, Psychometric and Crowdsourcing Analysis
2020
The use in psychology of crowdsourcing platforms as a method of data collection has been increasing in popularity because of its relative ease and versatility. Our goal is to adapt the Gratitude Questionnaire–20 Items (G20) to the English language by using data collected through a crowdsourcing platform. The G20 is a comprehensive instrument that takes in consideration the different basic processes of gratitude and assesses the construct’s cognitive, evaluative, emotional, and behavioral processes. We test the psychometric properties of the English version of the G20 with a Prolific (ProA) user sample. We assess the adequacy of the G20 for the crowdsourcing population in its English version…
Heterozygote advantage and pleiotropy contribute to intraspecific color trait variability
2022
The persistence of intrapopulation phenotypic variation typically requires some form of balancing selection because drift and directional selection eventually erode genetic variation. Heterozygote advantage remains a classic explanation for the maintenance of genetic variation in the face of selection. However, examples of heterozygote advantage, other than those associated with disease resistance, are rather uncommon. Across most of its distribution, males of the aposematic moth Arctia plantaginis have two hindwing phenotypes determined by a heritable one locus-two allele polymorphism (genotypes: WW/Wy = white morph, yy = yellow morph). Using genotyped moths, we show that the presence of o…
The impact of life stage and pigment source on the evolution of novel warning signal traits
2021
Our understanding of how novel warning color traits evolve in natural populations is largely based on studies of reproductive stages and organisms with endogenously produced pigmentation. In these systems, genetic drift is often required for novel alleles to overcome strong purifying selection stemming from frequency-dependent predation and positive assortative mating. Here, we integrate data from field surveys, predation experiments, population genomics, and phenotypic correlations to explain the origin and maintenance of geographic variation in a diet-based larval pigmentation trait in the redheaded pine sawfly (Neodiprion lecontei), a pine-feeding hymenopteran. Although our experiments c…
Linguistic, Contextual, and Experiential Equivalence Issues in the Adaptation of a Performance-Based Assessment of Generic Skills in Higher Education
2022
This qualitative study investigated the various linguistic, contextual, and experiential equivalence issues embedded in a performance-based instrument aimed at assessing generic skills in higher education. A rigorous translation and adaptation process (American English to Finnish) was conducted on one instrument, namely Collegiate Learning Assessment (CLA+) International. The data were obtained from cognitive laboratories (n = 13), with think-alouds and follow-up interviews conducted among Finnish undergraduate students. Content logs were created, and the data were analyzed thematically. The findings revealed that linguistic and contextual equivalence issues were more prominent than experie…
