Does the increase in body weight change the knee and ankle joint loading in walking and running?

2015

Previous obese studies showed that there is a correlation of weight to joint load in the knee joint during walking. In load-carrying studies, there are several studies but no consistent findings in the knee joint loads in walking and running. Our aim was to investigate how the joint load changes in body weight gaining, using added vest that was 10% of the body weight to mimic the conditions. We used Vicon eight-camera system and five force platforms with inverse dynamics to calculate the peak ground reaction forces(GRFs), joint angle, joint moments, and patellofemoral contact forces(PFCF), patellafemoral stress(PFS), peak patellofemoral tendon force(PTF) and peak Achilles tendon force (ATF)…

Impaired geometric properties of tibia in older women with hip fracture history.

2007

This study evaluated side-to-side differences in tibial mineral mass and geometry in women with previous hip fracture sustained on average 3.5 years earlier. Both tibial mineral mass and geometry were found to be reduced in the fractured leg. INTRODUCTION: The purpose of this study was to evaluate side-to-side differences in tibial mineral mass and geometry after hip fracture and to assess the determinants of such differences. METHODS: Thirty-eight 60- to 85-year-old women with a previous hip fracture and 22 same-aged control women without fractures participated in the study. Bone characteristics of the distal tibia and tibial shaft of both legs were assessed using pQCT in order to compare …

Speed-Related Energy Flow and Joint Function Change During Human Walking.

2021

During human walking, mechanical energy transfers between segments via joints. Joint mechanics of the human body are coordinated with each other to adapt to speed change. The aim of this study is to analyze the functional behaviors of major joints during walking, and how joints and segments alter walking speed during different periods (collision, rebound, preload, and push-off) of stance phase. In this study, gait experiment was performed with three different self-selected speeds. Mechanical works of joints and segments were determined with collected data. Joint function indices were calculated based on net joint work. The results show that the primary functional behaviors of joints would n…

Kinematics and kinetics analysis of midfoot joints of 30 normal subjects during walking

2016

Abstract Introduction There is not enough evidence in form of clinical studies regarding the behavior of the midfoot joints in dynamic situations such us walking or running. The present work aims to study the mechanical behavior of midfoot joints with a multisegmented foot model with special interest in joint moments and their clinical significance. Subjects and methods A computerized 3-dimensional gait study was performed on healthy male adult subjects with a neutral Foot Posture Index (FPI) (from 0 to +5) during walking. Joint angle and external moments were estimated with a multisegment foot model that considers three separate segments (forefoot, rearfoot and hallux) and graphs and value…

The impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease

2021

This study investigated the impact of Nordic walking on bone properties in postmenopausal women with pre-diabetes and non-alcohol fatty liver disease (NAFLD). A total of 63 eligible women randomly participated in the Nordic walking training (AEx, n = 33), or maintained their daily lifestyle (Con, n = 30) during intervention. Bone mineral content (BMC) and density (BMD) of whole body (WB), total femur (TF), femoral neck (FN), and lumbar spine (L2-4) were assessed by dual-energy X-ray absorptiometry. Serum osteocalcin, pentosidine, receptor activator of nuclear factor kappa-B ligand (RANKL) levels were analyzed by ELISA assay. After an 8.6-month intervention, the AEx group maintained their BM…

Associations of physical performance and physical activity with mental well-being in middle-aged women

2021

Abstract Background To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women. Methods Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule…

The association between perceived environmental barriers and walking activity among older adults

2011

With increasing age, people become less physically active, partly due to increased vulnerability to environmental demands. The aim of this study was to investigate the association between perceived barriers in the outdoor environment and walking activity among older adults. These analyses form part of the Screening and Counseling for Physical Activity and Mobility project (SCAMOB). The study design was cross-sectional. The participants were 75-81-year-old, able to walk independently outdoors, not highly physically active and were living in the center of Jyväskylä (N=632, 159 men, 473 women). Walking activity and environmental barriers were assessed with self-reports. An indicator of environ…

ContrAzioni di presidio e mitigazione

2022

Partendo dalla concezione di "rischio" e contrapponendola a quella di "azzardo", il testo introduce il lavoro di indagine e le proposte interattive nate durante e in seguito dell'esperienza del Laboratorio del cammino che nel 2021 attraversavai territori in contrazione delle province di Torino e Biella. Starting from the concept of "risk" and opposing it with that of "hazard", the text introduces the investigation work and the interactive proposals developed during and following the experience of the "Laboratorio del Cammino" which in 2021 crossed the shrinking territories of the Turin and Biella provinces.

Pioniere. Abitare territori in contrazione

2022

Partendo da una difficoltà che è quella di dare un nome a dimensioni che non hanno chiara definizione, il testo introduce il lavoro di indagine e di progetto sviluppato durante e in seguito al Laboratorio del Cammino 2022. In questa occasione si sono attraversati i territori in contrazione delle province di Biella e Torino e lo sguardo è stato rivolto ai/alle pionieri/e (umani e non) capaci di abitare un territorio alle volte ostile ma ricco di nuove possibilità. Starting from the effort needed to name realities that have no clear definition, the contribution introduces the field research and project work developed during and after the "Laboratorio del Cammino", 2022. On this occasion, terr…
