Mitochondrial bioenergetic pathways in blood leukocyte transcriptome decrease after intensive weight loss but are rescued following weight regain in …
2021
Prolonged periods of energy deficit leading to weight loss induce metabolic adaptations resulting in reduced energy expenditure, but the mechanisms for energy conservation are incompletely understood. We examined 42 healthy athletic females (age 27.5 +/- 4.0 years, body mass index 23.4 +/- 1.7 kg/m(2)) who volunteered into either a group dieting for physique competition (n = 25) or a control group (n = 17). The diet group substantially reduced their energy intake and moderately increased exercise levels to induce loss of fat mass that was regained during a voluntary weight regain period. The control group maintained their typical lifestyle habits and body mass as instructed. From the diet g…
Molecular Pathways Mediating Immunosuppression in Response to Prolonged Intensive Physical Training, Low-Energy Availability, and Intensive Weight Lo…
2019
Exercise and exercise-induced weight loss have a beneficial effect on overall health, including positive effects on molecular pathways associated with immune function, especially in overweight individuals. The main aim of our study was to assess how energy deprivation (i.e., "semi-starvation") leading to substantial fat mass loss affects the immune system and immunosuppression in previously normal weight individuals. Thus, to address this hypothesis, we applied a high-throughput systems biology approach to better characterize potential key pathways associated with immune system modulation during intensive weight loss and subsequent weight regain. We examined 42 healthy female physique athle…
Lifestyle counseling to reduce body weight and cardiometabolic risk factors among truck and bus drivers – a randomized controlled trial
2015
Objectives We conducted a randomized trial among overweight long-distance drivers to study the effects of structured lifestyle counseling on body weight and cardiometabolic risk factors. Methods Men with waist circumference > 100 cm were randomized into a lifestyle counseling (LIFE, N=55) and a reference (REF, N=58) group. The LIFE group participated in monthly counseling on nutrition, physical activity, and sleep for 12 months aiming at 10% weight loss. After 12 months, the REF group participated in 3-month counseling. Assessments took place at 0, 12, and 24 months. Between-group differences in changes were analyzed by generalized linear modeling. Metabolic risk (Z score) was calculated fr…
Nopean painonpudotuksen vaikutukset kehon koostumukseen sekä neste- ja hormonitasapainoon kansallisen huipputason painijoilla
2007
Sarkkinen, Pasi 2007. Nopean painonpudotuksen vaikutukset kehon koostumukseen sekä neste- ja hormonitasapainoon kansallisen huipputason painijoilla. Liikuntabiologian laitos, Jyväskylän yliopisto. Pro Gradu –tutkielma. Nopean ja suuren painonpudotuksen vaikutuksia urheilijan elimistöön on tutkittu verrattain vähän ja mahdollisia terveydellisiä riskejä ei ole juurikaan tiedostettu. Nopea painonpudotus on hyvin yleisesti käytetty menetelmä painoluokkalajeissa, kun normaalipaino ylittää kilpailusarjan. Painijoiden painon pudotus ala- ja keskisarjoissa on useimmiten 5-8 kg eli 8-12 % kehonpainosta. 18 tervettä suomalaista painijaa osallistui kreikkalais-roomalaisen tyylin SM-kilpailuihin (2004)…
Tarve laihduttaa : kyse ei ollutkaan pelkistä kiloista
2016
Jokinen, Emmi (2016). Tarve laihduttaa ― kyse ei ollutkaan pelkistä kiloista. Liikuntakasva- tuksen laitos, Jyväskylän yliopisto, liikuntapedagogiikan pro gradu –tutkielma, 56 sivua, 1 liite. Pro gradu –tutkielmani keskeinen tavoite oli selvittää kuinka tutkittavat henkilöt kuvaavat painon kertymistä, sen syitä ja toisaalta onnistunutta painonpudotusta ja sen taustalla vaikutta- via tekijöitä. Tavoitteena oli lisätä ymmärrystä siitä, mitkä tekijät vaikuttavat lihomiseen ja laihtumiseen. Tavoitteena oli myös kerätä kokemuksellista tietoa painonpudotuksesta yhtei- sössä nimeltä Herbalife. Tutkimus on toteutettu laadullisena tutkimuksena ja sen tieteenfilosofinen lähtökohta on feno- menologis-…

Do factors related to participation in physical activity change following restrictive bariatric surgery? A qualitative study.
2017
Summary Aims To explore participants’ ability to participate in physical activity (PA), and barriers and facilitators to PA, at 12 months following restrictive bariatric surgery, and how these differed from participants’ pre-surgery perceptions. Motivators for PA post-surgery were also explored. Methods Qualitative one-on-one in-depth interviews were conducted pre- and 12 months post-surgery. Data were analysed using inductive thematic analysis. Results Fourteen adults (12 females), with a mean (range) age of 41.4 years (25.0–56.0), body mass index (BMI) of 31.7 kg/m2 (22.3–48.2), and excess weight loss of 66% (2–127) completed both interviews. Lack of participation in PA during the first 3…
Theory-based digital intervention to promote weight loss and weight loss maintenance (Choosing Health)
2020
IntroductionDigital behavioural weight loss interventions have the potential to improve public health; however, these interventions are often not adequately tailored to the needs of the participants. This is the protocol for a trial that aims to determine the effectiveness and cost-effectiveness of the Choosing Health programme as a means to promote weight loss and weight loss maintenance among overweight/obese adults.Methods and analysisThe proposed study is a two-group randomised controlled trial with a nested interrupted time series (ITS) within-person design. Participants (n=285) will be randomly assigned to either the Choosing Health digital intervention or a control group. For interve…
Weight loss induces changes in adaptive thermogenesis in female and male physique athletes
2023
Physique athletes lose substantial weight preparing for competitions, potentially altering systemic metabolism. We investigated sex differences in body composition, resting energy expenditure (REE), and appetite-regulating and thyroid hormone changes during a competition preparation among drug-free physique athletes. The participants were female (10 competing (COMP) and 10 nondieting controls (CTRL)) and male (13 COMP and 10 CTRL) physique athletes. COMP were tested before they started their diet 23 weeks before competing (PRE), during their diet one week before competing (MID), and 23 weeks after competing (POST), whereas CTRL were tested at similar intervals but did not diet. Measurement…
Enabling transformative value creation through online weight loss services
2020
PurposeThis study aims to understand how online weight loss services could help customers achieve a durable change. The particular focus is on exploring the roles of value co-creation and well-being outcomes in reinforcing the transformative value potential, which is argued to be realized as customers’ intentions to continue a healthier lifestyle after the service period has ended.Design/methodology/approachData was collected from the participants of an online weight loss service (n = 498), and a conceptual research model was tested using structural equation modelling.FindingsThe results imply that compliance with the guidelines and social support are two value co-creation activities that c…
