Effects of aging and training on sprint performance, muscle structure and contractile function in athletes
2009
Cross-sectional studies were conducted to examine sprint running, anaerobic energy production and muscle properties in male sprinters aged 17-88 years. In addition, a 20-week training intervention was carried out to determine whether older runners can further improve their neuromuscular and performance characteristics by a greater emphasis on strength training. With age, sprint performance declined gradually (5-6%/decade). The slowing of maximum speed was characterized by a reduction in stride length and an increase in contact time along with lower ground reaction forces (GRF) and smaller leg and vertical stiffness during the contact phase. Stride frequency showed small decline while swing …
On the correlation of psychological characteristics within recreational marathon runners
2015
Oschwald Miles, 2015. On the Correlation of Psychological Characteristics Within Recreational Marathon Runners. Master’s Thesis in Sport and Exercise Psychology. Department of Sport Science. University of Jyväskylä. University of Jyväskylä. 40 p. The purpose of this research study was to explore the performance related experiences of recreational marathon runners. Specifically, the relationship these experiences have with other psychological constructs involved in undertaking and maintaining participation in a given sport. Using self-report measures the psychobiosocial states prior to most successful performances, achievement goal orientations, motivation and regulation for sport participat…
Individualized Endurance Training Based on Recovery and Training Status in Recreational Runners
2022
Purpose Long-term development of endurance performance requires a proper balance between strain and recovery. While responses and adaptations to training are highly individual, this study examined whether individually-adjusted endurance training based on recovery and training status would lead to greater adaptations compared to a predefined program. Methods Recreational runners were divided into predefined (PD, n = 14) or individualized (IND, n = 16) training groups. In IND, the training load was decreased, maintained or increased twice a week based on nocturnal heart rate variability, perceived recovery, and heart rate-running speed index. Both groups performed three-week preparatory, six-…
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…

ABBA, IKEA och köttbullar : kulturundervisningen i läroböckerna avsedda för årskurs sju i B-svenska
2014
Tutkimuksemme tarkoituksena on selvittää, kuinka ruotsalainen kulttuuri Ruotsissa ja Suomessa esitellään seitsemännen luokan B-ruotsin oppikirjoissa. Lisäksi tarkastelemme, eroavatko oppikirjojen tavat esittää kulttuuria toisistaan sekä vertailevatko kirjat näitä kahta kulttuuria keskenään. Selvitämme myös noudattavatko oppikirjat nykyisen opetussuunnitelman asettamia tavoitteita kulttuurin suhteen. Tutkimusaineistonamme ovat oppikirjat Megafon 1 (2012) ja Pågång 7 (2011). Jaoimme kulttuurielementit yhdeksään eri kategoriaan, jotka ovat1) musiikki, 2) kirjallisuus, 3) elokuvat, 4) urheilu, 5) maantieto ja historia, 6) yhteiskunta ja arkielämä, 7) ruoka, 8) juhlat ja perinteet ja 9) muut.

Brief an Garlieb H. Merkel
1797
Ms. 930a, Nr. 5, Bl. 11r-14v Recke, Charlotte Elisabeth (Elisa) Constantia v. der. Brief an Garlieb H. Merkel, Pyrmont (?), d[en] 8. May 1797 Autora rokraksts / Autograph, vācu un franču val. / Deutsch und Französisch [8] lpp. / S. Attēlu numuri / Bildnummern: 930a-005-1 – 930a-005-8 Der Brief von Elisabeth von der Recke wurde wahrscheinlich in Pyrmont verfasst. Die Autorin bezieht sich auf einen Brief Merkels, auf den sie antwortet. Sie äußert ihre grundsätzliche Zustimmung zur Idee einer Befreiung der Bauern in Liv- und Kurland und kann als Besitzerin zweier Güter, die ihr von der Kaiserin Katharina II. übereignet wurden, als Adressatin von Merkels Forderungen, die er in „Die Letten“ form…
Physiological, Perceptual, and Performance Responses to the 2-Week Block of High- versus Low-Intensity Endurance Training
2022
Purpose This study examined the physiological, perceptual, and performance responses to a 2-week block of increased training load and compared whether responses differ between high-intensity interval (HIIT) and low-intensity (LIT) endurance training. Methods Thirty recreationally trained males and females performed a two-week block of 10 HIIT-sessions (INT, n = 15) or 70 % increased volume of LIT (VOL, n = 15). Running time in the 3000 m and basal serum and urine hormone concentrations were measured before (T1) and after the block (T2), and after a recovery week (T3). In addition, weekly averages of nocturnal heart rate variability (HRV) and perceived recovery were compared to the baseline.…
Truncation, Information, and the Coefficient of Variation
1989
The Fisher information in a random sample from the truncated version of a distribution that belongs to an exponential family is compared with the Fisher information in a random sample from the un- truncated distribution. Conditions under which there is more information in the selection sample are given. Examples involving the normal and gamma distributions with various selection sets, and the zero-truncated binomial, Poisson, and negative binomial distributions are discussed. A property pertaining to the coefficient of variation of certain discrete distributions on the non-negative integers is introduced and shown to be satisfied by all binomial, Poisson, and negative binomial distributions.
A comparison between two feature selection algorithms
2017
This article provides a comparison of two feature selection algorithms, Information Gain Thresholding and Koller and Sahami's algorithm in the context of text document classification on the Reuters Corpus Volume 1 dataset. The algorithms were evaluated by testing the performance of classifiers trained on the features they select from a given dataset. Results show that Koller and Sahami's algorithm consistently outperforms Information Gain Thresholding by capturing interactions between features and avoiding redundancy among features, although it achieves its gains through increased complexity and longer running time.
