Acute hormonal and muscular responses and recovery : chronic adaptations to single session combined strength and endurance training with regard to or…
2012
Combining both strength (S) and endurance (E) exercise loadings into a single training session can be considered to be of interest e.g. for time management purposes. However, the first loading in a combined session tends to produce notable acute fatigue responses, which can lead to the second loading being performed in a compromised state. Research on fatigue and recovery from a combined session with different loading orders is currently scarce, with even less attention given to the acute responses. Thus, this study investigated the long-term adaptations in the acute responses of a combined strength and endurance loading and whether or not there is an order effect. A total of 29 male subjec…
Water immersion methods do not alter muscle damage and inflammation biomarkers after high-intensity sprinting and jumping exercise
2020
Purpose The aim of this study was to compare the efficacy of three water immersion interventions performed after active recovery compared to active recovery only on the resolution of inflammation and markers of muscle damage post-exercise. Methods Nine physically active men (n = 9; age 20‒35 years) performed an intensive loading protocol, including maximal jumps and sprinting on four occasions. After each trial, one of three recovery interventions (10 min duration) was used in a random order: cold-water immersion (CWI, 10 °C), thermoneutral water immersion (TWI, 24 °C), contrast water therapy (CWT, alternately 10 °C and 38 °C). All of these methods were performed after an active recovery (1…
Resistance Training Induces Antiatherogenic Effects on Metabolomic Pathways
2019
Introduction: Arising evidence suggests that resistance training has the potential to induce beneficial modulation of biomarker profile. To date, however, only immediate responses to resistance training have been investigated using high-throughput metabolomics whereas the effects of chronic resistance training on biomarker profile have not been studied in detail. Methods: A total of 86 recreationally active healthy men without previous systematic resistance training background were allocated into i) a resistance training (RT) group (n=68, age 33 ± 7 years, body mass index (BMI) 28 ± 3 kg/m2 ) and ii) a non-RT group (n=18, age 31 ± 4 years, BMI 27 ± 3 kg/m2 ). Blood samples were collected at…
Kuntosaliharrastajien rituaalit, identifikaatio ja motivaatio
2015
Tutkielmassa tarkastellaan kuntosaliharrastusta rituaalisena toimintana, joka rakentaa identiteettejä symbolisten rajojen kautta. Työssä etsitään myös vastausta siihen, minkälaisia identiteettejä kuntosaliharrastajille muodostuu kuntosalirituaalissa. Tutkielmassa selvitetään lisäksi kuntosaliharrastajien motivaatiota säännölliseen harjoitteluun. Kuntosaliharrastus on osa monien ihmisten elämää, mutta etnologista tutkimusta siitä on tehty vähän. Opinnäytetyö paikkaa tätä vajetta. Tutkielma tuottaa kansanterveydellisesti hyödynnettävää tietoa, koska se lisää ymmärrystä siitä, mitä liikuntasuositukset tarkoittavat ihmisten arjessa ja merkitysmaailmassa. Se tuo myös näkyviin niitä monitasoisia …
Velocity-based resistance training: do women need greater velocity loss to maximize adaptations?
2021
Abstract Purpose Men and women typically display different neuromuscular characteristics, force–velocity relationships, and differing strength deficit (upper vs. lower body). Thus, it is not clear how previous recommendations for training with velocity-loss resistance training based on data in men will apply to women. This study examined the inter-sex differences in neuromuscular adaptations using 20% and 40% velocity-loss protocols in back squat and bench press exercises. Methods The present study employed an 8-week intervention (2 × week) comparing 20% vs. 40% velocity-loss resistance training in the back squat and bench press exercises in young men and women (~ 26 years). Maximum strengt…
A 10-Week Block of Combined High-Intensity Endurance and Strength Training Produced Similar Changes in Dynamic Strength, Body Composition, and Serum …
2020
Purpose: To examine the potential sex differences in adaptations to combined endurance and strength training in recreationally endurance trained (eumenorrheic) women (n = 9) and men (n = 10). Methods: Isometric (ISOMmax) and dynamic bilateral leg press (1RM), countermovement jump (CMJ), running performance (3,000 m time trial), lean mass and body fat % (LEAN and FAT% determined by dual X-ray absorptiometry) as well as serum testosterone and cortisol (TES and COR, respectively, measured using hormone-specific immunoassay kits) were examined before a control period and pre, mid, and post a supervised 10-week combined high-intensity interval endurance training (4 × 4 min intervals and 3 × 3 × …

Optimising Training Adaptations and Performance in Military Environment
2018
Abstract Objectives Worldwide decreases in physical fitness and increases in body fat among youth have set challenges for armed forces to recruit physically capable soldiers. Therefore, knowledge of optimizing physical adaptation and performance through physical training is vital. In addition, maintaining or improving physical performance among professional soldiers in various military environments is crucial for overall military readiness. The present review focuses on the effects of military training on physical performance by searching for optimal methods to do it. Design and methods Review article based on selected literature searches using the main keywords ‘physical performance’ and ‘…
Performance changes during repeated military occupational test and its associations to physical performance
2023
The present study investigated performance changes during three runs (1 min recovery) of repeated military simulation task test (RMST) and its associations with physical performance. Voluntary male soldiers (N = 114) participated in a series of measurements of physical performance. Lower body explosive force production, anaerobic endurance and upper body strength endurance together explained 58% of the variance in the first RSMT (p < 0.001). The same variables explained the variance in the second and third runs of RSMT by 60% and 51%, but explosive force production was replaced with aerobic endurance, assessed by the 3.2 km loaded run (p < 0.001). This study demonstrated that the role of ex…
KRITOKY-tutkimus : valmiustason ylläpito matalakuormitteisissa kriisinhallintaoperaatioissa edellyttää voima- ja kestävyysharjoittelua
2020
Kuormittumisesta ja fyysisestä harjoittelusta sotilasoperaatioiden aikana on julkaistu kansainvälisestikin varsin vähän tutkimustietoa. Kriisinhallintajoukkojen toimintakykytutkimuksen (KRITOKY) tarkoituksena oli selvittää sotilaiden kuormittumista ja fyysistä aktiivisuutta Libanonin UNIFIL-rauhaturvaoperaatiossa kuuden kuukauden seurantajakson aikana. Lisäksi tutkittiin yhdistetyn voima- ja kestävyysharjoittelun vaikutuksia sotilaiden kehon koostumukseen, hengitys- ja verenkiertoelimistön sekä hermolihasjärjestelmän toimintakykyyn, seerumin hormonitasoihin sekä sotilaan tehtäväkohtaiseen toimintakykyyn. KRITOKY-tutkimus osoitti, että kriisinhallintaoperaation fyysinen kuormitus oli mittaus…
