Comparison of the roles of common constitutional and behavioural parameters in back performance estimates

2006

Objective: To compare the associations between different physical activity histories and anthropometric measures in isokinetic lifting performance, isometric back extension endurance and psychophysical lifting tests. Background: The relative roles and interaction of these factors related to back function are largely unknown. Methods: The subjects consisted of a population-based sample of 210 working-age males. Paraspinal muscle cross-sectional areas were obtained by magnetic resonance imaging; anthropometric measures, isokinetic and psychophysical lifting capacity, and isometric back extension endurance tests were performed and current and physical activity histories and occupational loadin…

EFFECTS OF A SPECIFIC FLEXIBILITY TRAINING PROGRAM ON SPINAL RANGE OF MOTION IN OLDER WOMEN

2013

Introduction Aging-related reduced spinal mobility can interfere with the execution of important functional skills and activities in elderly women. However there is a lack of studies about the effects of range of motion exercises on flexibility outcomes in older populations and a lack of consensus regarding the prescription of stretching exercises for older adults (ACSM, 2009). For these reasons the purpose of this study was to examine the extent to which spinal extension and flexion could be improved in a population of older women participating in a 8-week flexibility training program. Methods Thirty female volunteers were cluster randomized into either a control group [CG] (n: 13; age: 69…

Combined strength and endurance exercise induced fatigue and recovery

2012

Muscular fatigue is usually defined as the inability to maintain a given exercise intensity or adequate muscle force and therefore maximal isometric force, neural activation and fast force production capacity have often used determinants of acute fatigue. The purpose of the present study was to measure the acute effects of combined strength and endurance exercise on force production, muscle activation and work economy. In addition this study investigated the rate of recovery comparing the active and passive recovery models and the association of the initial fitness levels of subjects. 16 (27 ± 4 years old) male reservists performed combined strength (5x10x70%RM leg-press) and endurance (5x1…

Acute incremental endurance performance and explosive strength training period : muscle activity, acid-base balance and hormonal responses

2015

Johdanto. Akuutin kestävyys- ja voimaharjoituksen fysiologiset vasteet ilmenevät luurankolihaksissa, hengitys- ja verenkiertoelimistössä, sekä endokriinisessa että immuunijärjestelmässä. Nämä vasteet voivat heikentää suorituskykyä, ja esimerkiksi happo-emästasapaino on tarkoin säädelty negatiivisten seurausten varalta. Lihasten toimintaa voidaan tutkia elektromyografialla (EMG), ja nykyään on myös mahdollista käyttää tekstiilielektrodeja, jotka mahdollistavat lihasryhmien sähköisen aktiivisuuden tallentamisen normaalin liikkumisen aikana. Tämän tutkimuksen tarkoituksena oli tutkia yhteyksiä etu- ja takareisien lihasaktiivisuuksien ja happo-emästasapainon välillä, vertailla lihasaktiivisuuks…

Body Weight, Physical Activity, and Risk of Cancer in Lynch Syndrome

2021

Simple Summary Lifestyle modifies cancer risk in the general public. How lifestyle modifies cancer risk in individuals carrying the inherited pathogenic gene variants in DNA mismatch repair genes (Lynch syndrome) remains understudied. We conducted a retrospective study with cancer register data to investigate associations between body weight, physical activity, and cancer risk among Finnish Lynch syndrome carriers (n = 465, 54% women). The results of our study indicated that longitudinal weight gain increases cancer risk, whereas being highly physically active during adulthood could decrease cancer risk in men. Further, women were observed to be less prone to lifestyle-related risk factors …

Risk of Low Energy Availability, Disordered Eating, Exercise Addiction, and Food Intolerances in Female Endurance Athletes

2022

Relative energy deficiency in sport (RED-S) is a complex syndrome describing health and performance consequences of low energy availability (LEA) and is common among female endurance athletes. Various underlying causes of LEA have been reported, including disordered eating behavior (DE), but studies investigating the association with exercise addiction and food intolerances are lacking. Therefore, the aim of this cross-sectional study was to investigate the association between DE, exercise addiction and food intolerances in athletes at risk of LEA compared to those with low risk. Female endurance athletes, 18–35 years, training ≥5 times/week were recruited in Norway, Sweden, Ireland, and Ge…

High-Intensity Functional Training Induces Superior Training Adaptations Compared With Traditional Military Physical Training

2023

Helén, J, Kyröläinen, H, Ojanen, T, Pihlainen, K, Santtila, M, Heikkinen, R, and Vaara, JP. High-intensity functional training induces superior training adaptations compared with traditional military physical training. J Strength Cond Res XX(X): 000–000, 2023—This study examined the effectiveness of concurrent strength and endurance training with an emphasis on high-intensity functional training (HIFT) during military service. Voluntary male conscripts (aged 18–28 years) were placed in either an experimental (EXP: n = 50–66) or a control (CON: n = 50–67) group. The training for the EXP group included HIFT using body mass, sandbags, and kettlebells. The CON group trained according to the cur…

Physical training considerations for optimizing performance in essential military tasks

2022

Physically demanding essential military tasks include load carriage, manual material handling and casualty evacuation. This narrative review characterizes the main physical attributes related to performance of these occupational tasks and reviews physical training intervention studies in military settings to improve performance in these military tasks. Load carriage performance requires both aerobic and neuromuscular fitness with greater emphasis on maximal strength and absolute maximal oxygen uptake, especially when carrying heavier loads. In manual material handling, maximal strength and power are strongly associated with discrete lifting, while muscular strength, muscular endurance and a…

Development of an individualized familiarization method for vertical jumps

2013

OBJETIVO: Propor um método de familiarização individualizado para saltos verticais e verificar o seu efeito na variabilidade intrassujeito. MÉTODOS: Cinquenta e três homes (média ± DP; idade 23,5 ± 3,3 anos; estatura 1,76 ± 0,08 m; massa 72,8 ± 8,6 kg; percentual de gordura 12,9 ± 5,2%) realizaram sucessivos saltos até atingir o nível de estabilidade proposto. Após 48 h este processo era repetido e a estabilidade entre dias era verificada, se necessário, mais sessões eram realizadas. O nível de estabilidade foi determinado por um teste z, com intervalo de confiança de 95%. Após o processo de familiarização, duas sessões experimentais adicionais foram realizadas para determinar a confiabilid…
