Heart rate dynamics and lactate following high-intensity race-pace continuous vs interval workouts in highly trained athletes.
2020
AbstractPurposeThe present study aimed to compare the physiological responses of high-intensity race-pace continuous vs. interval workouts commonly used in middle-distance athletics, by means of analyzing post-exercise cardiac autonomic regulation and lactate.MethodsNineteen highly-trained 800-m male runners were asked to run a 600-m race-pace continuous workout and a 2 × 4 × 200-m interval training, counterbalanced and randomized within one week of difference. Blood lactate jointly with linear and nonlinear heart rate dynamics were assessed during the immediate 15-min recovery. Age-category (Under23-Senior vs. Juvenile-Junior) was considered as an inter-subject factor.ResultsPeak lactate w…
Technique and safety aspects of resistance exercises: a systematic review of the literature.
2009
A systematic review of the scientific literature was conducted to identify the optimal ranges of motion for preventing injury in the main joints of the body during resistance exercise performance. These ranges of motion are independent of the type in which the resistance exercises could be applied (ie, adults, elderly, athletes, recreational exercisers), and the regions examined include the shoulder, spine, and knee, which are injured most often. It can be concluded that during the performance of any resistance exercise, it is possible to put anatomical structures at risk with certain body positions; therefore, it is necessary to understand these movements so injury can be avoided.
Muscular failure training in conditioninig neuromuscular programs
2010
Many recommendations for designing of resistance training programs are suggested training all the sets to perform until voluntary fatigue with a maximum load selected, situation known as muscular failure. However, recent evidence has emerged that suggest caution in the prescription of training to failure in both, healthy and performance perspective. This review has addressed to this issue and made a collection of literature and a qualitative analysis of this topic. Final conclusion of this study suggest that implementation of the muscular failure resistance training is not recommended in subjects who trained with healthy goals, because it breaks the acceptable risk-benefit ratio in healthy …
PGC-1 isoforms and their target genes are expressed differently in human skeletal muscle following resistance and endurance exercise
2015
The primary aim of the present study was to investigate the acute gene expression responses of PGC-1 isoforms and PGC-1a target genes related to mitochondrial biogenesis (cytochrome C), angiogenesis (VEGF-A), and muscle hypertrophy (myostatin), after a resistance or endurance exercise bout. In addition, the study aimed to elucidate whether the expression changes of studied transcripts were linked to phosphorylation of AMPK and MAPK p38. Nineteen physically active men were divided into resistance exercise (RE, n = 11) and endurance exercise (EE, n = 8) groups. RE group performed leg press exercise (10 9 10 RM, 50 min) and EE walked on a treadmill (~80% HRmax, 50 min). Muscle biopsies were ob…
The changes in proportion and body composition of a woman practicing group fitness training for three months
2020
Background: Physical activity is an excellent form of prevention of modern diseases. The most popular form of physical activity chosen by women is group fitness activities. Women are most likely to focus on exercises for the lower parts of the body (thighs, buttocks, abdomen). In recent years, dance classes (e.g. Zumba) or exercises on mini trampolines have become very popular. Regular fitness training contributes to positive changes in the proportions and body composition. Aim of the study: The aim of the study was to assess the proportions and body composition of a woman via a 3-month group fitness training program. Case report: The study involved a woman aged 26, participating in fitness…

Effects of long-term lifestyle and high-intensity interval training intervention on blood pressure reduction in patients with abdominal obesity
2013
Purpose: The aims of this study were: 1) to study the impact of a combined long-term lifestyle and high-intensity interval training (HIIT) intervention on blood pressure (BP) in patients with abdominal obesity; 2) To document BP reduction responses according to the European Society of Hypertension BP classification. Methods: 105 patients with abdominal obesity (age: 53±10 yrs; 32 men; waist circumference (WC): 112±13cm; systolic/diastolic (SBP/DBP): 133±13/82±8 mmHg; 11% diabetics, 11% smokers, 68% with antihypertensive therapy) were retrospectively analyzed before and after a combined long-term lifestyle and HIIT program twice a week. Anthropometric measurements, cardiometabolic risk facto…
Innovative Educational Pathways in Spine Surgery: Advanced Virtual Reality–Based Training
2020
Background Over the past few years, a reorganization of the educational pathways has been promoted with the purpose of optimizing the acquisition of competences and their assessment, so as to reduce the risks to both health care professionals and end users. Virtual reality (VR) has been repeatedly tested, initially as a positive reinforcement for more traditional educational pathways and, more recently, as their potential substitute. The aim of this study was to demonstrate the potentiality of VR simulation training in spine surgery. Methods The VR simulator reproduced the lateral lumbar access to the spine. The simulation included a tutorial, the preoperative settings, and the surgical ses…
Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners
2015
The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…
Adaptations to aerobic interval training: interactive effects of exercise intensity and total work duration
2011
To compare the effects of three 7-week interval training programs varying in work period duration but matched for effort in trained recreational cyclists. Thirty-five cyclists (29 male, 6 female, VO(2peak) 52 ± 6 mL kg/min) were randomized to four training groups with equivalent training the previous 2 months (∼6 h/wk, ∼1.5 int. session/wk). Low only (n=8) trained 4-6 sessions/wk at a low-intensity. Three groups (n=9 each) trained 2 sessions/wk × 7 wk: 4 × 4 min, 4 × 8 min, or 4 × 16 min, plus 2-3 weekly low-intensity bouts. Interval sessions were prescribed at the maximal tolerable intensity. Interval training was performed at 88 ± 2, 90 ± 2, and 94 ± 2% of HR(peak) and 4.9, 9.6, and 13.2 …
