Performance of Host-Races of the Fruit Fly,Tephritis conuraon a Derived Host Plant, the Cabbage ThistleCirsium oleraceum: Implications for the Origin…
2008
The thistle-infesting fruit fly Tephritis conura Loew (Diptera: Tephritidae) forms host races on the melancholy thistle, Cirsium hetewphyllum (L.) Hill (Asterales: Asteraceae) and the cabbage thistle, Cirsium olemceum (L.). Scop. Previous research indicates that the host shift occurred from C. hetewphyllum to C. oleraceum. In this paper we address whether the host shift involved physiological adaptations by studying oviposition acceptance and survival of the two host races on the derived host C. oleraceum. Performance differed significantly between host races. T. conura originating from C. oleraceum produced adults in 75% of all egg-laying trials in contrast to only 6.6% in T. conura origin…
Effect of the Game Design, the Goal Type and the Number of Players on Intensity of Play in Small-Sided Soccer Games in Youth Elite Players
2015
Abstract The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not f…
Adherence to an Injury Prevention Warm-Up Program in Children’s Soccer : A Secondary Analysis of a Randomized Controlled Trial
2021
This study examined the impact of high adherence to a neuromuscular training (NMT) warm-up on the risk of lower extremity (LE) injuries in children’s soccer. Twenty U11–U14 youth clubs (n = 92 teams, 1409 players) were randomized into intervention (n = 44 teams) and control (n = 48 teams) groups. The intervention group was advised to perform an NMT warm-up 2 to 3 times a week for 20 weeks. Team adherence, injuries, and exposure were registered throughout the follow-up. Primary outcomes were the incidence of soccer-related acute LE injuries and the prevalence of overuse LE injuries. Intervention teams conducted mean 1.7 (SD 1.0) NMT warm-ups weekly through follow-up. The seasonal trend for a…

Manipulating Individual Decisions and Environmental Conditions Reveal Individual Quality in Decision-Making and Non-Lethal Costs of Predation Risk
2012
Habitat selection is a crucial decision for any organism. Selecting a high quality site will positively impact survival and reproductive output. Predation risk is an important component of habitat quality that is known to impact reproductive success and individual condition. However, separating the breeding consequences of decision-making of wild animals from individual quality is difficult. Individuals face reproductive decisions that often vary with quality such that low quality individuals invest less. This reduced reproductive performance could appear a cost of increased risk but may simply reflect lower quality. Thus, teasing apart the effects of individual quality and the effect of pr…
Longitudinal associations of movement behaviours with body composition and physical fitness from 4 to 9 years of age: structural equation and mediati…
2023
Background The associations of movement behaviours (physical activity [PA], sedentary behaviour [SB], and sleep) with body composition and physical fitness from pre-school to childhood, as well as the direction of the associations, could provide important information for healthy lifestyle promotion in children. This study investigated the longitudinal and bidirectional associations of movement behaviours with body composition and physical fitness measured at 4 and 9 years of age. Methods This longitudinal study included baseline (n = 315, 4.5 [SD = 0.1] years) and follow-up data (n = 231, 9.6 [SD = 0.1] years) from the MINISTOP study. Movement behaviours were measured for 7 days using wrist…
Relationship between physical activity, fitness and brain morphology in youth
2017
Yhä useammat tutkimukset ovat havainneet yhteyden fyysisen aktiivisuuden, fyysisen kunnon ja kognitiivisten kykyjen välillä, mutta tätä yhteyttä selittävät tekijät ja siihen liittyvät muutokset aivojen rakenteissa ovat vielä varsin epäselviä. Tässä tutkimuksessa oli tarkoitus selvittää, onko fyysisellä aktiivisuudella tai fyysisellä kunnolla yhteyttä aivojen rakenteeseen nuorilla. Tutkimuksen koehenkilöt olivat 35 suomalaista nuorta (14.14 ±0.71 vuotta, 23 tyttöä & 12 poikaa), otanta laajemmasta AFIS (Active, Fit and Smart) -tutkimusprojektista. Tutkimuksessa mitattiin fyysistä aktiivisuutta objektiivisilla kiihtyvyysanturimittareilla, fyysistä kuntoa lasten ja nuorten mittaamiseen tarkoite…
Association of physical fitness on self- perceived work ability on working aged people
2016
Ageing population combined with plans of lengthen careers compel both organizations and occupational healthcare system to renew. Sufficient physical fitness is one of the key factors to pursuit this goal which enables workers to continue in the working life. Aim of the study was to clarify association of physical fitness on self- perceived work ability on working aged people by utilizing Laturi Energy Index and short version of Work Ability Index (WAP) questionnaire in a working age population. Study was a sub-study of a larger ALIWO research project. Altogether 197 participants, 39 executives and 158 employees from 39 local companies in different sectors took part to the study. Energy Inde…
Physical fitness characteristics and neck and shoulder pain incidence in school‐aged children—A 2‐year follow‐up
2022
Background and Aims Neck and shoulder pain (NSP) is common in school age, but preventative factors have not been identified. The purpose was to study whether a fitness test could be used to predict the incidence of NSP and determine whether good physical fitness characters would be associated with lower NSP incidence in school-aged children at 2-year follow-up. Methods After the invitation to nine schools, 970 children (10–15 years old) agreed to participate. Flexibility, fundamental movement skills, musculoskeletal fitness, and cardiorespiratory fitness measurements included in Finnish Schools on the Move! monitoring system for physical functional capacity were measured at baseline in 2013…
A scalable school‐based intervention to increase early adolescents' motor competence and health‐related fitness
2023
Schools are key settings for the promotion of students' physical activity, fitness, and motor competence. The purpose of our study was to investigate the efficacy of a 5-month-long intervention program that aimed to increase students' motor competence and health-related fitness during school days. We conducted a quasi-experimental study with 325 Finnish Grade 5 (Mage = 11.26, SD = 0.33) students from five schools. Two schools were allocated to the intervention group and three schools to the control group. The intervention consisted of three components: (a) weekly 20 min session during regular PE lessons, (b) weekly 20 min session during recess, and (c) daily 5-minute-long classroom activity…
