Ringeten lajianalyysi ja valmennuksen ohjelmointi

2016

Työn tarkoitus. On tiedossa, että ringetestä lajina ei ole aiemmin tehty kattavaa lajianalyysiä ja lajia koskevaa materiaalia on koottu yhteen niukasti. Tämän lajianalyysin tarkoituksena oli vastata tähän tarpeeseen kokoamalla yhteen tietoa ringetteharjoittelun lajikokonaisuudesta ja lajin fysiologisista vaatimuksista. Fyysisten tekijöiden ohella tässä työssä on tarkoitus esitellä naisjoukkueen valmennuksellisia erityispiirteitä sekä joukkueurheilun psyykkistä valmennusta. Tämä lajianalyysi perustuu tieteellisiin julkaisuihin ja urheiluvalmennuksen asiantuntijoiden luentoihin sekä henkilökohtaisiin tiedonantoihin. Lajianalyysi. Kanadan maajoukkuepelaajien fyysisten testien (Webster ym. 1999…

ACTing for depressive symptoms : a longitudinal study of a brief 4-session acceptance- and value-based intervention for symptoms of depression

2018

The main objective of this study was to investigate a brief 4-session intervention based on a theoretical framework of acceptance and commitment therapy (ACT), and to explore its short- and long-term effectiveness among individuals reporting depressive symptoms. Additionally, the research aimed at further exploring the elements of psychological flexibility and mindfulness associated with improvements in depressive symptoms. The dissertation comprises three studies. Study I investigated the effectiveness of the brief intervention compared to a waiting-list control group. In total, 57 participants were randomized into either the ACT intervention (n = 28) or the waiting-list control (WLC; n = …

The effects of active vs. passive recovery on riding performance during a simulated motocross race

2021

Aims: Motocross consists of two races of 30 min with a break in between. Recovery between races is paramount to performance, this study aimed to compare the effects of active and passive recovery between motocross races on riding performance. Methods: Thirteen elite and non-elite racers performed two races of 30 min with 1 h break, twice with two-week interval. Between the races active (20 min ergometer cycling at 60% of HRmax) or passive recovery (no activity) were executed in a randomized order. Lap times, heart rate during riding, blood lactate, reaction time, handgrip strength, upper back pull strength, counter movement jump height, and medicine ball throw distance were measured before …

Relationships between Heart Rate Variability, Sleep Duration, Cortisol and Physical Training in Young Athletes.

2021

The aims of the current study were to examine the relationships between heart rate variability (HRV), salivary cortisol, sleep duration and training in young athletes. Eight athletes (16 ± 1 years) were monitored for 7 weeks during training and competition seasons. Subjects were training for endurance-based winter sports (cross-country skiing and biathlon). Training was divided into two zones (K1, easy training and K2, hard training). Heart rate and blood lactate during submaximal running tests (SRT), as well as cortisol, sleep duration and nocturnal HRV (RMSSD), were determined every other week. HRV and cortisol levels were correlated throughout the 7-week period (r = -0.552, P = 0.01), wi…

Shorter recovery time following high-intensity interval training induced higher body fat loss among overweight women

2018

Background: High intensity interval training (HIIT) has been widely employed as an exercise protocol to reduce fat, and also in addition, interval recovery periods are the most important factors which can have great impact on weight loss. Therefore, the aim of this study was the evaluation of different recovery time between HIIT program on metabolic responses and weight loss in overweight women. Methods: Twenty-four overweight (BMI 29.5±3.5 kg/m2) volunteer women were randomly assigned into three groups (n=8/group) to study the effects of different recovery times: (group 1; HIIT with 60/60 activity-rest ratio (sec), group 2; HIIT with 60/30 activity-rest ratio (sec), and group 3 was set as …

Kahden erilaisen muuttuvan vastuksen periaatteella toimivan voimaharjoittelulaitteen väliset erot nopeusvoimaväsytyksessä : akuutit vaikutukset miehi…

2004

Tutkimuksen tarkoituksena oli tutkia kahta toimintaperiaatteeltaan erilaista voimaharjoittelulaitetta nopeusvoimaväsytyksen aikana: ilmanpainelaitetta (Leg/Curl, Ab Hur Oy, Kokkola, Finland) ja painopakkalaitetta (David 200, David International Ltd, Vantaa, Finland). Myös sukupuolten välisiä eroja lihasväsymisessä tarkasteltiin nopeusvoimaväsytyksen ja akuutin palautumisen aikana. Koehenkilöinä toimi 16 (8 naista, 8 miestä) säännöllisesti liikuntaa harrastavaa nuorta. Koehenkilöt suorittivat nopeusvoima-tyyppisen väsytyksen (10 x 10, kuorma 30 – 40 % MVC) kahdella eri polvenojennus laitteella: ilmanpainelaitteella (IP) ja painopakkalaitteella (PP) siten, että väsytyksien välissä oli vähintä…

Oluen hivenainepitoisuuksien analysointi

2015

Tämän Pro gradu -tutkielman kirjallisessa osassa käsiteltiin hivenaineiden tarvetta palautumisen kannalta ja alkoholin tuottamia vaikutuksia palautumiseen. Lisäksi selvitettiin orgaanista ainesta sisältävien näytteiden esikäsittelymenetelmiä ja induktiivisesti kytketyn plasma-optisen emissiospektrometrin (ICP-OES) käyttöä hivenaineiden analysoinnissa. Ultraääni, mikroaalto, tuhkistus ja muita esikäsittelymenetelmiä ja niiden eroavaisuuksia ja eroja esiteltiin, koska oluen hivenaineanalyysien onnistumiseksi on erityisen tärkeää saada hiilidioksidi poistumaan näytetaustasta ja nämä menetelmät olivat hyväksi havaittuja kyseiseen toimintaan. Oluesta löytyy kirjallisuudesta hyvin vähän tutkimuks…

Neuromuscular, hormonal and molecular responses to heavy resistance training in strength trained men : with special reference to various resistance e…

2006

The present study was designed to obtain more information on mechanisms leading to muscle hypertrophy by determination of the effects of different heavy resistance exercise protocols on acute and chronic neuromuscular and hormonal responses in previously strength trained young men. The present study also examined gene expression of androgen receptors and insulin-like growth factor I (IGF-I) to further understand the adaptation mechanisms to resistance training. The present results suggest that increased resistance exercise intensity induced by the so-called forced repetitions (FR) exercise system may be beneficial for the development of muscle mass and muscle strength during strength traini…

Energetic demands and nutritional strategies of elite cross-country skiers during Tour de Ski : A narrative review

2021

The Tour de Ski (TDS: 6–9 sprint and distance races across 9–11 days) represents the most intense competition series of the cross-country (XC) ski season and is characterized by accumulated stress from consecutive days of high-intensity (~ 85%–160% VO2max) racing, travel, cold temperatures and low to moderate altitude (500–1500 m above sea level). Here, nutritional strategies play a key supportive role for optimized health, recovery and performance. This narrative review aims to provide an evidence-based discussion on the energetic demands of the TDS and recommendations for nutritional strategies to optimize health and performance of XC skiers during and following the TDS. We highlight seve…
