Using Virtual Reality to Distract Overweight Children from Bodily Sensations During Exercise
2016
This study analyzes the potential of virtual reality (VR) to enhance attentional distraction in overweight children as they experience bodily sensations during exercise. It has been suggested that one reason why obese children stop exercising is the perception of bodily sensations. In a counterbalanced design, a total of 109 children (33 overweight, 10-15 years old) were asked to walk twice for 6 minutes on a treadmill under one of two conditions: (a) traditional condition (TC)-focusing their attention on their physical feelings and sensations or (b) distraction condition (DC)-focusing their attention on a virtual environment. Attentional focus during exercise, bad-good feeling states (pre-…
The Duke treadmill score with bicycle ergometer: Exercise capacity is the most important predictor of cardiovascular mortality
2018
Background The Duke treadmill score, a widely used treadmill testing tool, is a weighted index combining exercise time or capacity, maximum ST-segment deviation and exercise-induced angina. No previous studies have investigated whether the Duke treadmill score and its individual components based on bicycle exercise testing predict cardiovascular death. Design Two populations with a standard bicycle testing were used: 3936 patients referred for exercise testing (2371 men, age 56 ± 13 years) from the Finnish Cardiovascular Study (FINCAVAS) and a population-based sample of 2683 men (age 53 ± 5.1 years) from the Kuopio Ischaemic Heart Disease study (KIHD). Methods Cox regression was applied for…

Effects of Conjugated Linoleic Acid and Endurance Training on Peripheral Blood and Bone Marrow of Trained Mice
2007
Fat supplements, especially conjugated linoleic acid (CLA), are increasingly popular ergogenic aids among endurance athletes. To evaluate the importance of fat supplementation in the practice of endurance sports, we investigated the effects of CLA supplementation on body weight, muscle hypertrophy, peripheral blood composition, and bone marrow composition in healthy, young, endurance-trained mice. Young, healthy mice were subdivided into control, trained, and treated groups, according to their running attitudes. Training was performed over a period of 6 weeks on a treadmill, at a gradually increasing duration and speed. CLA-treated groups were gavaged with 0.425 mg x d(-1) CLA supplement fo…
Effects of age and life-time physical training on fibre composition of slow and fast skeletal muscle in rats.
1987
The effects of age and endurance training on muscle fibre characteristics were studied in a slow (m. soleus, MS) and in a fast (m. rectus femoris, MRF) skeletal muscle. Wistar rats at ages of 1, 2, 4, 10, and 24 months were used as experimental animals. The trained rats were put to run on a motor-driven treadmill 5 d/wk beginning from the age of 1 month. The body weights of the animals increased continuously throughout their lives. The muscle weights increased up to the age of 10 months, after which they tended to decrease. The trained adult rats had lower body weights as well as lower muscle weights than the untrained adult rats. The amount of the intramuscular lipid decreased with age, es…
Brain BDNF Levels Elevation Induced by Physical Training is Reduced after Unilateral Common Carotid Artery Occlusion in Rats
2014
International audience; We investigated the contribution of blood flow elevation in the cerebrovasculature to physical training-induced brain-derived neurotrophic factor (BDNF) levels elevation in the brain. Brain-derived neurotrophic factor protein levels were measured in the motor cortex 24 h after the last session of a forced treadmill walking (30 minutes a day, 18 m/minute for 7 consecutive days). Unilateral common carotid artery occlusion and modulation of exercise intensity (0 versus -10% inclination of the treadmill) were used as strategies to reduce the (normal) elevation of flow in the cerebrovasculature occurring during exercise. Administration of N-nitro-L-arginine methyl ester (…
Maximal isometric strength indices are associated with the oxygen cost of walking and running in recreationally active men and women.
2021
This study assessed the associations of maximal isometric strength and movement economy in 126 recreationally active men and women. Oxygen consumption was assessed through a graded treadmill test with 4-minute increments (4-12 km∙h
Influence of visual cues on gait in Parkinson's disease during treadmill walking at multiple velocities.
2011
Abstract Objective To evaluate the interaction of different treadmill-induced gait velocities and visual cues on the gait performance in Parkinson's disease (PD). Background External cuing has been reported to facilitate hypokinetic gait patterns in PD. Methods 19 PD-patients and 17 controls volunteered for the study. Gait analyses were conducted using dynamic pressure sensors integrated in a treadmill at a given velocity of 1, 2, 3 or 4 km/h. For each velocity, measurements were performed under three conditions. The first condition was without visual cuing, the remaining two consisted of visual cuing e.g. white stripes put on the treadmill belt 25 or 50 cm apart. Results Visual cuing lower…
Wrist-worn accelerometers in assessment of energy expenditure during intensive training
2012
We assessed the ability of the Polar activity recorder (AR) to measure energy expenditure (EE) during military training. Twenty-four voluntary male conscripts participated in the study and wore an AR on the non-dominant wrist 24 h a day for 7 d. The AR analyzed and stored the frequency of hand movements (f_hand) into memory at 1 min intervals. The relationship between f_hand and EE was studied over a 7 d period of military training using the doubly labeled water (DLW) technique. In addition, the relationship between f_hand and EE was analyzed during walking and running on a treadmill with an indirect calorimeter (IC), and f_hand was measured during a supervised 45 min field march test where…
Effects of physical training on metabolism of connective tissues in young mice.
1980
The effects of physical training on the metabolism of collagen, calcium and glycosaminoglycans in various connective tissues were studied in male NMRI mice. The mice to be trained and their controls were about 3 weeks old (expt. I) and 8 weeks old (expt. II) at the commencement of training. The training was performed on a 5 degree inclined treadmill 5 days a week for 4 weeks in expt. I and for 3 weeks in expt. II. The daily exercise time was progressively increased from 20 min in the first week up to 80 min in the third week. The incorporation of 3H-proline to collagen hydroxyproline was increased by training in long bones, skeletal muscle and Achilles tendon, whereas the incorporation of 3…
