Anemia, heart failure and exercise training

2013

We read with interest the recent article by Wang et al. in which theauthors evaluated in anemic patients with heart failure whether exer-tionalperiodicbreathing influences rheological/hemodynamicfunctions[1]. For this purpose, the authors performed an incremental exercisetestusing a bicycle ergometer. In this regard, it has been generally assumedby some researchers, exercise physiologists and scientists that the incre-ment in blood hemoglobin (Hb) content is among the main hematolog-ical adaptations to endurance exercise training. This misconception isbased in the data published in diffe rent studies carried out severalyearsago [2].Inarecentmanuscript byBakeretal. [3],theauthorsdem-onstrated…

Circulating irisin detection: Does it really work?

2015

The recent discovery of irisin has generated considerable interest in the scientific community. However, many studies on the biochemistry and biology of this intriguing hormone yielded controversial results in humans, which were mostly attributable to a number of drawbacks in the methods used for its detection and measurement.

The effects of a calisthenics training intervention on posture, strength and body composition

2017

BACKGROUND: Calisthenics was a term used to define a generic set of body weight exercises. Such term is now used to define a world wide spread discipline based on body weight and gymnastics exercises.OBJECTIVE: The aim of this study was to administer a calisthenics training protocol and evaluate its effects on posture, strength and body composition in untrained individuals.METHODS: Twenty-eight male participants (24.2 +/- 4.2 years; 67.0 +/- 8.3 Kg; 173.3 +/- 5.2 cm) were divided into two groups, a Calisthenics based intervention group (SG) and a control group (CG). The SG exercised for 8 weeks. Each participant underwent a body composition analysis, a postural assessment, a handgrip test, …

Unilateral Conditioning Contractions Enhance Power Output in Elite Short Track Speed Skaters

2018

AbstractThe objective of the present study was to assess the effect of unilateral lower-body-conditioning muscle contractions during multiple sets of fatiguing repeated jumps in elite athletes. Five elite short-track speed-skating athletes performed 9 sets of 6 maximal consecutive jumps on 2 separate occasions: with (COND) and without (CTRL) preliminary voluntary conditioning contractions (CC) 5 min before the beginning of the sets. The CC consisted of 2 consecutive 3 s maximal unilateral isometric squats against a fixed bar, resulting in a 6 s overall isometric contraction per leg. For each set, power output (PO) was measured using a linear position transducer and averaged over the 6 corre…

Cross-Country Skiing and Running’s Association with Cardiovascular Events and All-Cause Mortality:A Review of the Evidence

2019

A large body of evidence demonstrates positive, graded effects of PA on cardiovascular disease (CVD) morbidity and mortality with increasing intensity compared with lower PA intensity. Running is often designated as a high-intensity PA with substantial evidence supporting its health benefits. Cross-country skiing is among the most demanding aerobic endurance exercises and requires engaging the upper- and lower-body. Cross-country skiing is often regarded as high-intensity PA, which has been associated with significant health benefits. However, a robust body of evidence identifying the dose-response relation between cross-country skiing volume and health outcomes is sparse. Therefore, this r…

Aerobic Exercise During Advance Stage of Uncontrolled Arterial Hypertension

Made available in DSpace on 2022-04-29T08:45:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-06-03 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Universidade Estadual Paulista Aim: To evaluate the influence of physical training on myocardial function, oxidative stress, energy metabolism, and MAPKs and NF-κB signaling pathways in spontaneously hypertensive rats (SHR), at advanced stage of arterial hypertension, which precedes heart failure development. Methods: We studied four experimental groups: normotensive Wistar rats (W, n = 27), trained W (W-EX, n = 31), SHR (n = 27), and exercised SHR (SHR-E…

Digital Coaching among University Students with Low Levels of Physical Activity: A Quantitative Intervention Study on Exercise Self-efficacy

2019

University aged people have been found to be at a high risk of disengagement of physical activity. They also belong to a generation where technology is strongly integrated into most parts of their lives. Therefore, using technology also in physical activity promotion has potential. This exploratory study investigates the perceived effects of a sport and wellness technology digital coach among physically inactive university students during a 10-week intervention. The perspective for the research came from exercise psychology focusing on the effects of the use of a digital coach on self-efficacy related to physical activity and exercising. The results indicate that a digital coach can increas…
