Keski-ikäisten miesten ja naisten maksimaalisen hapenottokyvyn kehitys puolen vuoden aikana
2004
Henriikka Järveläinen. Keski-ikäisten miesten ja naisten maksimaalisen hapenottokyvyn kehitys puolen vuoden aikana. Liikuntafysiologian Pro gradu-tutkielma (liikuntabiologian laitos). Syksy 2004. Jyväskylän yliopisto. Asiasanat: Maksimaalinen hapenottokyky, submaksimaalinen polkupyöräergometritesti, työkyky, keski-ikäiset Tämän tutkimuksen tarkoituksena oli tutkia vaikuttaako testausinterventio 50-vuotiaiden Helsingin kaupungin työntekijöiden maksimaalisen hapenottokyvyn kehitykseen, ja aktivoiko testaukseen osallistuminen liikunnan harrastuneisuuden kasvua. Työhypoteesi tässä tutkimuksessa oli, että testausinterventio aktivoi 50-vuotiaista ihmistä kehittämään maksimaalista hapenottokykyä s…
Nutritional intake and anthropometric characteristics are associated with endurance performance and markers of low energy availability in young femal…
2023
Background Low energy availability (LEA) can have negative performance consequences, but the relationships between LEA and performance are poorly understood especially in field conditions. In addition, little is known about the contribution of macronutrients to long-term performance. Therefore, the aim of this study was to evaluate if energy availability (EA) and macronutrient intake in a field-based situation were associated with laboratory-measured performance, anthropometric characteristics, blood markers, training volume, and/or questionnaire-assessed risk of LEA in young female cross-country (XC) skiers. In addition, the study aimed to clarify which factors explained performance. Metho…
Acute Neuromuscular and Hormonal Responses to Power, Strength, and Hypertrophic Protocols and Training Background
2022
This study investigated how two slightly different athlete groups would differ in acute neuromuscular and endocrine responses to specific resistance exercise loadings and recovery compared to untrained participants. Power athletes (PA, n = 8), strength athletes (SA, n = 8) and non-athletes (NA, n = 7) performed power (PL, 7 × 6 × 50% of 1RM), maximal strength (MSL, 7 × 3 × 3RM), and hypertrophic (HL, 5 × 10 × 10RM) loadings in Smith-machine back-squat. Neuromuscular performance, serum testosterone, growth hormone, and cortisol concentrations, and blood lactate (BL) were measured before (Pre), at Mid and after (Post) loading, and after recovery for 24 and 48 h. All loadings led to acute decr…
Neuromuscular Performance and Hormonal Profile During Military Training and Subsequent Recovery Period
2019
Introduction Military training loads may induce different physiological responses in garrison and field training and only a little is known about how short-time recovery, lasting a few days, affects neuromuscular fitness and hormonal profile. This study aimed to investigate the effects of garrison and field military service on neuromuscular performance and hormonal profile and to evaluate the effects of a 3-day recovery on those factors. Methods Twenty healthy male soldiers (20 ± 1 years) participated in the study, which consisted of 4 days of garrison training [days (D) 1–4] and 7 days of military field training (Days 5–12) followed by a 3-day recovery period (Day 15). Serum hormone concen…
Effects of Task-Specific and Strength Training on Simulated Military Task Performance in Soldiers.
2020
A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…
Acute neuromuscular and hormonal responses to 20 versus 40% velocity loss in males and females before and after 8 weeks of velocity-loss resistance t…
2022
Scientific examination of velocity-based resistance training (VBRT) has increased recently, but how males and females respond to different VBRT protocols or how these acute responses are modified after a period of training is unknown. Habitually resistance-trained males and females followed either a 20 or 40% velocity-loss programme for 8 weeks. Acute squat loading tests (five sets, 70% one-repetition maximum load, 3 min rest) were performed before and after the training period. Tests of maximum neuromuscular performance and blood sampling were conducted before, within 10 min of completion (POST) and 24 h after each acute loading test. Testing included countermovement jump, resting femoral …
Physiotherapy for the functioning of breast cancer patients : studies of the effectiveness of physiotherapy methods and exercise, of the content and …
2005
These studies were undertaken to create a broader understanding of the effectiveness of physiotherapy methods and exercise, and to evaluate the requirements, content and timing of physiotherapy services after breast cancer surgery.The first study, critical review and meta-analysis, showed that with shoulder movements after breast cancer surgery the whole range of motion movements should be delayed for several days. The review indicates that methods of lymphedema therapy are various, but only some have scientific support for their effectiveness. The use of an elastic sleeve is supported by the studies. Lymph massage alone has not been studied, and the effect of exercise on the prevention and…
Required competency in organization
2017
Tässä pro gradu – tutkimuksessa tarkoituksena on selvittää mitä kompenssivaatimuksia data analytiikassa on ja mitkä kompetenssit ovat tärkeimpiä asiakkaalle luodun arvon kannalta. Tutkimuksessa on hyödynnetty mixed method – lähestymistapaa, jossa yhdistetään määrillisen ja laadullisen tutkimuksen elementtejä. Empiirinen tutkimus pohjautuu kirjallisuuskatsauksen tuloksiin. Empiirinen tutkimus toteutettiin sähköisin kyselylomakkein, jotka sisälsivät sekä strukturoituja että avoimia kysymyksiä. Tutkimukseen osallistui 18 henkilöä kolmesta eri yrityksestä. Strukturoitujen kysymysten vastaukset valmisteltiin kuvailevien tilastomenetelmien avulla ja analysoitiin verraten löydöksiä kirjallisuuskat…
Salibandypelaajan suorituskykyprofiili ja muutokset sarjakauden aikana
2015
Janne Kainulainen (2015). Salibandypelaajan suorituskykyprofiili ja muutokset sarjakauden aikana. Valmennus- ja testausoppi, pro gradu -tutkielma, Liikuntabiologian laitos, Jyväskylän yliopisto, 78 s. Salibandy on noussut Suomessa yhdeksi suosituimmista urheilulajeista. Lajilla on omat ominaispiirteensä harjoittelussa ja fysiologisessa kuormittavuudessa. Tutkimuksen tarkoituksena oli selvittää salibandypelaajan suorituskykyprofilia ja kauden aikaisia muutoksia suorituskyvyssä. Menetelmät. Tutkimusjoukkona oli miesten Salibandyliigan joukkue (n=18), keski-ikä 24 ± 4 vuotta. Tutkimusjakso kesti Salibandyliigakauden 2013–2014 toukokuusta helmikuuhun. Tutkimus jakautui kahteen osaan; (1) kauden…
