Effect of saddle height on skin temperature measured in different days of cycling
2016
Infrared thermography can be useful to explore the effects of exercise on neuromuscular function. During cycling, it could be used to investigate the effects of saddle height on thermoregulation. The aim of this study was to examine whether different cycling postures, elicited by different knee flexion angles, could influence skin temperature. Furthermore, we also determined whether the reproducibility of thermal measurements in response to cycling differed in the body regions affected or not affected by saddle height. Sixteen cyclists participated in three tests of 45 min of cycling at their individual 50 % peak power output. Each test was performed in a different knee flexion position on …
Spinal and supraspinal mechanisms affecting torque development at different joint angles
2015
INTRODUCTION We examined the neural mechanisms responsible for plantar flexion torque changes at different joint positions. METHODS Nine subjects performed maximal voluntary contractions (MVC) at 6 ankle-knee angle combinations [3 ankle angles (dorsiflexion, anatomic position, plantar flexion) and 2 knee angles (flexion, full extension)]. Neural mechanisms were determined by V-wave, H-reflex (at rest and during MVC), and electromyography during MVC (RMS), normalized to the muscle compound action potential (V/Msup, Hmax/Mmax, Hsup Msup and RMS/Msup) and voluntary activation (VA), while muscle function was assessed by doublet amplitude. RESULTS MVC and doublet amplitude were significantly low…
The arterial blood supply of the temporomandibular joint: an anatomical study and clinical implications
2013
Purpose: The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Materials and Methods: Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. Results: The analysis …
Comparison of Postoperative Coronal Leg Alignment in Customized Individually Made and Conventional Total Knee Arthroplasty
2021
Neutral coronal leg alignment is known to be important for postoperative outcome in total knee arthroplasty (TKA). Customized individually made implants (CIM) instrumented with patient-specific cutting guides are an innovation aiming to increase the precision and reliability of implant positioning and reconstruction of leg alignment. We aimed to compare reconstruction of the hip–knee–ankle angle (HKA) of the novel CIM system iTotal™ CR G2 (ConforMIS Inc.) to a matched cohort of the off-the-shelf (OTS) knee replacement system Vanguard™ CR (Zimmer Biomet). Retrospective analysis of postoperative coronal full-leg weight-bearing radiographs of 562 TKA (283 CIM TKA, 279 OTS TKA) was conducted. V…
The pain threshold of high-threshold mechanosensitive receptors subsequent to maximal eccentric exercise is a potential marker in the prediction of D…
2017
Background Delayed-onset muscle soreness (DOMS) refers to dull pain and discomfort in people after participating in exercise, sport or recreational physical activities. The aim of this study was to detect underlying mechanical thresholds in an experimental model of DOMS. Methods Randomised study to detect mechanical pain thresholds in a randomised order following experimentally induced DOMS of the non-dominant arm in healthy participants. Main outcome was the detection of the pressure pain threshold (PPT), secondary thresholds included mechanical detection (MDT) and pain thresholds (MPT), pain intensity, pain perceptions and the maximum isometric voluntary force (MIVF). Results Twenty volun…

Superwomen? Young sporting women, temporality and learning not to be perfect
2020
New forms of neoliberal femininity create demanding horizons of expectation for young women. For talented athletes, these pressures are intensified by the establishment of dual-career discourses that construct the combination of high-performance sport and education as a normative, ‘ideal’ pathway. The pressed time perspective inherent in dual-careers requires athletes to employ a variety of time-related skills, especially for young women who aim to live up to ‘superwoman’ ideals that valorise ‘success’ in all walks of life. Drawing on existential phenomenology, and in-depth interviews with 10 talented Finnish sportswomen (aged 19–22), we explored their experiences of lived time when pursui…
Shorter recovery time following high-intensity interval training induced higher body fat loss among overweight women
2018
Background: High intensity interval training (HIIT) has been widely employed as an exercise protocol to reduce fat, and also in addition, interval recovery periods are the most important factors which can have great impact on weight loss. Therefore, the aim of this study was the evaluation of different recovery time between HIIT program on metabolic responses and weight loss in overweight women. Methods: Twenty-four overweight (BMI 29.5±3.5 kg/m2) volunteer women were randomly assigned into three groups (n=8/group) to study the effects of different recovery times: (group 1; HIIT with 60/60 activity-rest ratio (sec), group 2; HIIT with 60/30 activity-rest ratio (sec), and group 3 was set as …
Narrative Tensions in Strained Junior Elite Performers’ Experiences of Becoming Elite Performers
2021
Contextualized within narrative theory and the field of talent identification and development systems (TIDS), this interview study examined strained junior elite performers’ experiences of becoming elite performers while participating in prestigious national TIDS. The study explored how junior elite performers perceive and negotiate their personal narratives of becoming within a cultural master narrative of being. The focus is on how the quality of person-environment interaction, characterized by narrative alignment or tensions, relates to perceptions of identity, agency, and physical and mental health. We purposefully recruited eight participants (Mage = 17.31, SD = 0.9) from a previously …
Zadovoljavanje osnovnih psiholoških potreba i autonomna motivacija u kontekstu škole: testiranje aditivne, sinergističke i hipoteze ravnoteže
2018
The present study examined the influence of the three basic psychological needs on autonomous motivation in educational settings in the light of additive, synergistic, and balance hypotheses. Participants were 679 high school students (Mage = 16.16, 49.3% girls). The findings supported the additive hypothesis: all three needs had unique effects on autonomous motivation. The synergistic hypothesis was only partially supported: one two-way interaction between autonomy and competence had effect on autonomous motivation. A high level of satisfaction of the need for autonomy led to autonomous motivation regardless of satisfaction of the need for competence. However, competence was positively rel…
