An Integrative Cognitive Behavioral Therapy Program for Adults With Migraine: A Feasibility Study
2019
Objective To present a novel cognitive behavioral therapy program that was developed exclusively for adults with migraine, and to assess the feasibility of this program. Background Unlike previous efforts, we combined different approaches of behavioral therapy into one program: relaxation therapy, cognitive behavioral therapy, trigger management. Methods The treatment program consists of 7 sessions (including psychoeducation, lifestyle counseling, coping with fear of attacks, trigger management, and stress management). The research was conducted in a single-group study with N = 9 completers (age: M = 41.6, SD = 17.6 years; N = 8 female, N = 1 male; N = 5 migraine without aura, N = 2 migrain…
Relationship of drug-addicted patients' personality disorders to social problem-solving changes during the rehabilitation process.
2012
Drug-addicted patients exhibit various personality disorders that interfere with their adaptation to society, as well as their ability to participate in the rehabilitation process. The Latvian Rehabilitation Programme for drug addicts includes social problem-solving training to help patients reintegrate into society. However, the role of personality disorders has not been investigated in relation to this process.The aim of the study is to assess whether personality disorders predict changes in dimensions of social problem-solving after 6 months of rehabilitation for drug-addicted patients.The sample of this study consists of 31 drug-addicted patients from the Latvian rehabilitation centres …
Impaired exercise tolerance is associated with increased urine albumin excretion in the early stages of essential hypertension
2011
Background: Our aim was to investigate the relationship between impaired exercise capacity and albumin excretion level in the setting of never treated essential hypertension. Design and methods: For this purpose, 338 consecutive essential hypertensives (52 ± 8.5 years, 227 males, office BP = 148.6/96.1 mmHg) performed a negative for myocardial ischemia, maximal treadmill exercise testing and were classified based on the gender specific median value of the amount of metabolic equivalents (METs) achieved (10.1 ml/kg/min for women and 11 ml/kg/min for men) as fit ( n = 177) and unfit ( n = 161). All the participants underwent 24-h ambulatory BP monitoring, complete echocardiographic study inc…
The role of posterior parietal cortices on prismatic adaptation effects on the representation of time intervals
2013
Previous studies provided evidence of an ascending left-to-right spatial representation of time durations by using a technique affecting high levels of spatial cognition, i.e. prismatic adaptation (PA). Indeed, PA that induced a leftward aftereffect distorted time representation toward an underestimation, while PA that induced a rightward aftereffect distorted time representation toward an overestimation. The present study advances previous findings on the effects of PA on time by investigating the neural basis subtending these effects. We focused on the posterior parietal cortex (PPC) since it is involved in the PA procedure and also in the formulation of the spatial representation of time…
Neuromuscular adaptations to combined strength and endurance training: order and time-of-day
2017
AbstractThe present study examined the effects of 24 weeks of morning vs. evening same-session combined strength (S) and endurance (E) training on neuromuscular and endurance performance. Fifty-one men were assigned to the morning (m) or evening (e) training group, where S preceded E or vice versa (SEm, ESm, SEe and ESe), or to the control group. Isometric force, voluntary activation, EMG and peak wattage during the maximal cycling test were measured. Training time did not significantly affect the adaptations. Therefore, data are presented for SEm+e (SEm+SEe) and ESm+e (ESm+ESe). In the morning, no order specific gains were observed in neuromuscular performance. In the evening, the changes …
Neuromuscular and hormonal adaptations in athletes to strength training in two years.
1988
Neuromuscular and hormonal adaptations to prolonged strength training were investigated in nine elite weight lifters. The average increases occurred over the 2-yr follow-up period in the maximal neural activation (integrated electromyogram, IEMG; 4.2%, P = NS), maximal isometric leg-extension force (4.9%, P = NS), averaged concentric power index (4.1%, P = NS), total weight-lifting result (2.8%, P less than 0.05), and total mean fiber area (5.9%, P = NS) of the vastus lateralis muscle, respectively. The training period resulted in increases in the concentrations of serum testosterone from 19.8 +/- 5.3 to 25.1 +/- 5.2 nmol/l (P less than 0.05), luteinizing hormone (LH) from 8.6 +/- 0.8 to 9…
The order effect of combined endurance and strength loadings on force and hormone responses: effects of prolonged training
2014
Purpose To examine acute responses and recovery of force and serum hormones to combined endurance and strength loadings utilizing different orders of exercises before and after training. Methods Physically active men were matched to an order sequence of endurance followed by strength (E + S, n = 12) or strength followed by endurance (S + E, n = 17). The subjects performed one experimental loading consisting of steady-state cycling and a leg press protocol before and after 24 weeks of order-specific combined training. Results No between-group difference in acute reductions of force was observed at week 0 (E + S −23 %, p < 0.001; S + E −22 %, p < 0.01) and 24 (E + S −25 %, p < 0.001; S + E −2…
Neural drive preservation after detraining following neuromuscular electrical stimulation training
2006
The purpose of the study was to investigate the behaviour of the central nervous system when 5 weeks of neuromuscular electrical stimulation (NMES) training was followed by 5 weeks of detraining. Nineteen males were divided into the neuromuscular electrostimulated group (EG, n=12) and the control group (CG, n=7). The training program consisted of 15 sessions of isometric NMES over a 5-week period. The EG subjects were tested before training (PRE), after 5 weeks of NMES training (POST) and after 5 weeks of detraining (DE) while CG subjects were only tested at PRE and at POST. Soleus (SOL) and gastrocnemii (GAS) maximal H-reflex and M-wave potentials were evoked at rest (i.e., H(max) and M(ma…
Similar increases in strength after short-term resistance training due to different neuromuscular adaptations in young and older men
2014
This study investigated whether differences in neuromuscular performance and muscle hypertrophy occur between young and older men. Twenty-three young (29 ± 9 years) and 26 older men (64 ± 8 years) completed 10 weeks of high-volume, medium load “hypertrophic” resistance training with low frequency (twice per week) with 10 young (34 ± 11 years) and 11 older men (65 ± 3 years) acting as nontraining control subjects. Training consisted of 2–5 sets of 8–14 repetitions (1- to 2-minute rest). Lower-limb dynamic (leg press) and isometric maximum leg extension force, as well as lower-limb lean mass and vastus lateralis cross-sectional area were assessed before and after the training period. Training…
Effect of time-of-day-specific strength training on muscular hypertrophy in men.
2009
The purpose of the present study was to examine effects of time-of-day-specific strength training on muscle hypertrophy and maximal strength in men. A training group underwent a 10-week preparatory training (wk 0-wk 10) scheduled between 17:00 and 19:00 hours. Thereafter, the subjects were randomized either to a morning or afternoon training group. They continued with a 10-week time-of-day-specific training (wk 11-wk 20) with training times between 07:00 and 09:00 hours and 17:00 and 19:00 hours in the morning group and afternoon groups, respectively. A control group did not train but was tested at all occasions. Quadriceps femoris (QF) cross-sectional areas (CSA) and volume were obtained b…
