Increased fascicle length but not patellar tendon stiffness after accentuated eccentric-load strength training in already-trained men

2020

Purpose This study examined whether additional external load during the eccentric phase of lower limb strength training exercises led to greater adaptations in knee extensor strength, muscle architecture, and patellar tendon properties than traditional concentric–eccentric training in already-trained men. Methods Twenty-eight men accustomed to strength training were randomized to undertake 10 weeks of supervised traditional (TRAD) or accentuated eccentric loading (AEL) or continue their habitual unsupervised (CON) strength training. TRAD and AEL trained 2∙week−1 with a six-repetition maximum (RM) session and a ten-RM session. TRAD used the same external load in both concentric and eccentric…

Dietary intake and strength training adaptation in 50-70 -year old men and women : with special reference to muscle mass, strength, serum anabolic ho…

2007

Frailty has been defined as an age-related decrease of the physiologic systems that results in weakness, weight loss and decreased functional performance, thus increasing the risk of disability. The physical characteristics of frailty are affected by the amount of muscle mass and strength. Strength training (ST) can alleviate age-related declines in muscle mass, strength and physical function. However, there is controversy regarding whether dietary intake can improve the effects of ST. The present thesis assessed the effects of dietary intake (DI) on muscular, hormonal and metabolic adaptations to ST in healthy 50-70 year old people. In cross-sectional study I, maximal strength of the leg e…

Leisure activities and well-being in midlife and older age with special reference to physical activity and resistance training

2019

Participation in leisure activities is related to better well-being. Participation in leisure time physical activity also has several positive effects on functional capacity and health. Notwithstanding, only a minor proportion of adults, including older adults, participate in physical activity at a sufficient level for maintaining or improving their health. This study investigated both cross- sectional and longitudinal associations between different types of leisure and physical activities and well-being. This dissertation is based on data from three research projects: the Finland 2014 – Consumption and Lifestyle postal survey, conducted with a random sample representative of the Finnish ad…

Varusmiesten liikuntakoulutus osana Koulutus 2020 -uudistusta : tutkimusraportti

2022

Puolustusvoimien fyysisen koulutuksen tärkeimpänä tavoitteena on valmistaa sotilasta selviytymään omasta tehtävästään. Koulutus 2020 -ohjelman mukaisessa varusmieskoulutuksessa tavoitteena on kehittää liikuntakoulutusta siten, että varusmiesten kokonaisvaltainen toimintakyky parantuisi. Tämän tutkimuksen tarkoituksena on verrata uusimuotoisen ja suunnitelmallisen fyysisen toimintakyvyn harjoittelun vaikutuksia nykyiseen liikuntakoulutukseen tutkimalla varusmiesten kestävyys- ja voimaominaisuuksia, kognitiivista toimintakykyä, veren hormonipitoisuuksia, kehonkoostumusta ja terveyttä perus- (P), erikois- (E) ja joukko- (J) koulutuskausien aikana. Tutkimus toteutettiin Kainuun prikaatissa II/2…

Effects of resistance training frequency on muscle strength, activity and mass during a 24-week intervention in the elderly

2016

Elderly populations are increasingly affected by sarcopenia, dynapenia and osteoporosis. They all increase frailty and decrease quality of life and life-expectancy. Resistance training (RT) has been reported extensively as a tool that can prevent, counter and in some cases reverse the course of the abovementioned diseases. Several studies covering RT adaptations in elderly populations have investigated periods between 6 up to 88 weeks with different frequencies, from 1 to 3 trainings / week and a wide range of intensities (30-85% or one repetition maximum) and different volumes. The aim of this study was to investigate the effect of different training frequencies (one, two or three times / …

Exercise medicine for cancer cachexia: targeted exercise to counteract mechanisms and treatment side effects.

2022

Abstract Purpose Cancer-induced muscle wasting (i.e., cancer cachexia, CC) is a common and devastating syndrome that results in the death of more than 1 in 5 patients. Although primarily a result of elevated inflammation, there are multiple mechanisms that complement and amplify one another. Research on the use of exercise to manage CC is still limited, while exercise for CC management has been recently discouraged. Moreover, there is a lack of understanding that exercise is not a single medicine, but mode, type, dosage, and timing (exercise prescription) have distinct health outcomes. The purpose of this review was to examine the effects of these modes and subtypes to identify the most opt…

Effects of internal kinetics and muscle activity during the wide and narrow barbell back squat

2017

Lahti, J. 2017. Effects of internal kinetics and muscle activity during the wide and narrow barbell back squat. Sports biology department, University of Jyväskylä. Master’s thesis. p. 102 (4 attachments). Introduction. The barbell back squat (BBS) is a commonly utilized strength exercise to support general preparedness for the demands in multiple sports. Recently, studies have shown various strength training exercises have the potential to recruit the regions of the hamstrings differently. Specifically, it is unknown if changing stance width under conditions where forward knee movement is restricted engages the hamstring regions differently and how this corresponds with measured 3-D net joi…

Effects of barbell back squat stance width on sagittal and frontal hip & knee kinetics

2019

Different stance widths are commonly utilized when completing the barbell back squat during athletic general preparedness training. Width manipulation is thought to influence sagittal plane stimuli to the hip and knee extensors, the primary extensor musculature in the squat. However, how width manipulation affects frontal plane stimuli is less understood. Knowledge of hip and knee net joint moments (NJM) could improve exercise selection when aiming to improve sport‐specific performance and prevent injuries. Fourteen adult amateur rugby athletes were recruited for this study. After a familiarization period, participants performed wide‐ (WIDE, 1.5× greater trochanter width) and narrow‐stance …
