Myofascial Release Effects in Teachers' Posture, Muscle Tension and Voice Quality: A Randomized Controlled Trial.

Objective: Myofascial release (MFR) comprises a set of manual therapeutic techniques applied to many conditions, but specific evidence concerning its effects on body posture, muscle tension and voice has been lacking. Thus, the aim of this study was to verify the effects of MFR in teachers' posture, muscular tension and voice quality.

Study Design: Randomized controlled trial - crossover.

Associations Between Teachers' Autonomic Dysfunction and Voice Complaints.

Objective: This investigation aimed to verify if there were any differences in autonomic nervous system function and voice parameters of teachers with and without voice complaints.

Study Design: Cross-sectional study.

Methods: The Questionnaire of Autonomic Dysfunction was answered by 24 teachers, 6 males, and 18 females, whose heart rate variability was also assessed.

Associations between Teachers' Posture, Muscle Tension and Voice Complaints.

Objective: The interaction between muscle tension, posture, and vocal use is very complex as clinical research suggests that abnormal laryngeal posture can be associated with muscle adaptive changes, although specific evidence concerning body posture and voice disorders has been lacking. Thus, the aim of this study was to verify if there were differences in posture, muscle tension and voice between teachers with and without voice complaints.

Study Design: Cross-sectional study.

Acupuncture can be beneficial for exercise-induced muscle soreness: A randomised controlled trial.

Introduction: Strenuous physical exercise may cause acute muscle soreness (AMS), which occurs directly after exercise, as well as delayed onset muscle soreness (DOMS), which occurs about 24 h after exercise. Studies of acupuncture's effect on DOMS have had contradictory results, whereas its effect on AMS has not been extensively studied. The main goal of this study was to evaluate acupuncture's effects on AMS and DOMS and on the prevention of DOMS.

Associations Between Autonomic Nervous System Function, Voice, and Dysphonia: A Systematic Review.

Objective: The study aimed to verify the relation between autonomic nervous system (ANS) dysfunctions, voice, and dysphonia.

Study Design: The study is a systematic review.

Methods: According to the PRISMA flowchart, a search on Pubmed/Medline, SciELO, RCAAP, LILACS, Cochrane Library, PEDro, and Isi Web of Knowledge was performed up to April 2019 using the following key words: autonomic nervous system and voice or dysphonia.

Associations between Posture, Voice, and Dysphonia: A Systematic Review.

Objective: The study aimed to systematize the associations between posture, voice, and dysphonia in order to support future research directions and possible clinical interventions.

Study Design: The study is a systematic review.

Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart, a search on PubMed/Medline, SciELO, RCAAP, LILACS, Cochrane Library, PEDro, and Isi Web of Knowledge was performed from their inception through January of 2017 using the key words "posture" and ("voice" or "dysphonia").

The Effectiveness of Physiotherapy and Complementary Therapies on Voice Disorders: A Systematic Review of Randomized Controlled Trials.

Unlabelled: The treatment of voice disorders includes physiotherapy and complementary therapies. However, research to support these treatments is scarce.

Objective: to verify the effectiveness of physiotherapy and complementary therapies on voice disorders.

Eccentric exercise transiently affects mice skeletal muscle mitochondrial function.

Eccentric exercise (EE) is known to induce damage and dysfunction in skeletal muscle. However, the possible role of mitochondrial (dys)function, including the vulnerability to mitochondrial permeability transition pore (MPTP) opening, is unclear. Therefore, this study aimed to analyze the impact of a single acute bout of downhill running on skeletal muscle mitochondrial function.

Mitochondria as a target for exercise-induced cardioprotection.

Cardiac damage is a major contributor to the morbidity and mortality particularly associated with coronary artery disease. Moreover, it is also related to some metabolic diseases such as diabetes and to some side effects of drug treatments. Regular exercise has been confirmed as a pragmatic countermeasure to protect against cardiac injury.

Acute exercise protects against calcium-induced cardiac mitochondrial permeability transition pore opening in doxorubicin-treated rats.

The use of DOX (doxorubicin), an antibiotic used in oncological treatments, is limited by a dose-related cardiotoxicity against which acute exercise is protective. However, the mitochondrial-related mechanisms of this protection remain unknown. Therefore the present study aimed to determine the effects of an acute endurance exercise bout performed 24 h before DOX treatment on heart and liver mitochondrial function.

Endurance training reverts heart mitochondrial dysfunction, permeability transition and apoptotic signaling in long-term severe hyperglycemia.

The present study analyzed the effects of endurance training against cardiac mitochondrial dysfunction, particularly on the susceptibility to mitochondrial permeability transition pore (MPTP) induction in streptozotocin (STZ)-induced hyperglycemia. Twenty-four young male Wistar rats were randomly assigned into sedentary citrate (SED+CIT), sedentary type I diabetes (SED+STZ; 50mg/kg), T+CIT (14-week treadmill running, 60min/day) and T+STZ (injected 4weeks before training). After 18weeks, isolated heart mitochondria were used for in vitro oxygen consumption and transmembrane potential (∆Ψ) assessment.

Long-term hyperglycaemia decreases gastrocnemius susceptibility to permeability transition.

Background: Hyperglycaemia-resulting in mitochondrial bioenergetics' complications is associated with skeletal muscle dysfunction. The aim of this work was to analyse the effect of long-term severe hyperglycaemia on gastrocnemius mitochondrial bioenergetics, with special relevance on the susceptibility to mitochondrial permeability transition pore (MPTP) opening.

Methods: Sixteen adult (6- to 8-week-old) male Wistar rats were randomly divided into two groups (n = 8/group): control and diabetic.

Endurance training improves gastrocnemius mitochondrial function despite increased susceptibility to permeability transition.

The aim of the present work was to test the hypothesis that moderate endurance treadmill training ameliorates gastrocnemius mitochondrial bioenergetics and increases the tolerance to the calcium-induced mitochondrial permeability transition pore (MPTP) opening. Twelve adult (6-8 week old) male Wistar rats were randomly divided into two groups (n=6per group): sedentary and trained (14 week of endurance treadmill running, 60min/day). Several end-points for invitro gastrocnemius mitochondrial function including oxygen consumption, transmembrane electric potential and susceptibility to calcium-induced MPTP opening were evaluated.
