Different-day and same-session combined strength and endurance training : adaptations in neuromuscular and cardiorespiratory performance, body compos…
2017
This thesis investigated 1) acute neuromuscular and hormonal responses to combined strength and endurance loadings with different orders and their long-term adaptations (women), 2) adaptations in neuromuscular, hormonal, cardiorespiratory and health variables following 24 weeks of volume-equated protocols of combined training (men and women). Subjects were assigned to one of three groups: strength and endurance training on different days (DD: men n=21, women n=18), training in the same-session with either endurance before strength (ES: men n=16, women n=15) or vice versa (SE: men n=18, women n=14). DD trained 4-6 d·wk-1 with strength and endurance on alternating days. ES and SE trained 2-3 …
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…
Energy Balance, Hormonal Status, and Military Performance in Strenuous Winter Training
2023
Severe energy deficit may impair hormonal regulation and physical performance in military trainings. The aim of this study was to examine the associations between energy intake, expenditure, and balance, hormones and military performance during a winter survival training. Two groups were studied: the FEX group (n = 46) had 8-day garrison and field training, whereas the RECO group (n = 26) had a 36-h recovery period after the 6-day garrison and field training phase. Energy intake was assessed by food diaries, expenditure via heart rate variability, body composition by bioimpedance, and hormones by blood samples. Strength, endurance and shooting tests were done for evaluating military perform…
Voimaharjoittelun yhteydet hermo-lihasjärjestelmän suorituskykyyn, hormonipitoisuuksiin ja kehonkoostumukseen varusmieskoulutuksessa
2017
Tutkimuksen tausta ja tarkoitus. Suomalainen sotilas tarvitsee hyvää ammattitaitoa ja fyysistä suorituskykyä, ampumataitoa sekä maastossa liikkumisen taitoa. Puolustusvoimien fyysisen koulutuksen tärkeimmät osa-alueet ovat taistelu-, marssi- ja liikuntakoulutus, joista liikuntakoulutuksen määrä kokonaiskoulutusajasta on lähes puolet. Voimaharjoittelun tiedetään kehittävän lihaksiston sekä sen tukiosien, jänteiden ja sidekudosten voimaa, lisäävän tehoa, nopeutta ja motorista suorituskykyä sekä kasvattavan lihaksen poikkipinta-alaa ylläpitäen kehon rasvatonta massaa. Yleisen suorituskyvyn ja vammojen ennaltaehkäisyn lisäksi voimaharjoittelusta on hyötyä myös taakankantokykyyn, joka on sotilaa…
Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?
2022
Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…
