Effects of prolonged walking on neural and mechanical components of stretch responses in the human soleus muscle

2009

After repeated passive stretching, tendinous tissue compliance increases in the human soleus (SOL) muscle–tendon unit. During movement, such changes would have important consequences for neural and mechanical stretch responses. This study examined the existence of such effects in response to a 75 min walking intervention. Eleven healthy subjects walked on a treadmill at 4 km h−1 with a robotic stretch device attached to the left leg. Ultrasonography was used to measure SOL fascicle lengths, and surface EMG activity was recorded in the SOL and tibialis anterior (TA) muscles. Perturbations of 6 deg were imposed at three different measurement intervals: Pre (immediately before the walking inte…

Immediate effects of the respiratory stimulation on ventilation parameters in ischemic stroke survivors: A randomized interventional study (CONSORT).

2019

Background: Post-stroke brain damage, which affects the central control of respiration, leads to various respiratory disorders. They can be caused by the weakening of the respiratory muscles and chest movements, which can indirectly contribute to an impairment of the ventilation function. The aim of the study is an objective assessment of the effect of a single-session intervention of respiratory stimulation through Proprioceptive Neuromuscular Facilitation (PNF) on chosen respiratory parameters and the following comparison of these changes with a group in which positioning was used (intra- and intergroup comparison). Methods: This was a randomized interventional study evaluating the respir…

The Relation Between Stretching Typology and Stretching Duration: The Effects on Range of Motion.

2018

AbstractDifferent stretching strategies and protocols are widely used to improve flexibility or maintain health, acting on the muscle tendon-unit, in order to improve the range of motion (ROM) of the joints. This review aims to evaluate the current body of literature in order to understand the relation between stretching typology and ROM, and secondly to evaluate if a relation exists between stretching volume (either as a single training session, weekly training and weekly frequency) and ROM, after long-term stretching. Twenty-three articles were considered eligible and included in the quantitative synthesis. All stretching typologies showed ROM improvements over a long-term period, however…

Delayed onset muscle soreness (DOMS) management: present state of the art

2016

This paper reviews existing theories explaining the delayed onset muscle soreness (DOMS) phenomenon. The authors describe the main symptoms of DOMS and their relation to different kinds of training strategies, and discuss the most popular muscle pain reduction interventions such as stretching, diet, dietary supplements, nonsteroidal anti-inflammatory drugs (NSAIDs), cryotherapy and cold water immersion, concurrent training, and the repeated bout effect.

Peripheral Nerve Responses to Muscle Stretching: A Systematic Review

2021

Stretching is commonly used to increase range of motion and flexibility. Therefore, investigations are usually oriented towards the muscle-tendon unit. Limited evidence exists regarding potential effects of stretching on peripheral nerves which lie within muscles. The objective of this investigation will be to elucidate the responses of peripheral nerves to stretching. A literature search was performed using the following databases: Scopus, NLM Pubmed and ScienceDirect. Studies regarding the effects of stretching protocols on responses of peripheral nerves were retrieved for investigation. The NHLBI tool was used for quality assessment. Outcomes included nerve stiffness, nerve displacement,…

STUDY OF SAGITTAL SPINAL ROM IN ELDERLY WOMEN AFTER A SPECIFIC FLEXIBILITY-TRAINING PROGRAM

2013

The reduction of spinal mobility is one luckless consequence of the aging process. In particular, scarcity of exercise appears to be the principal reason of aging-related spinal dysfunction syndrome, which is characterized by adaptive shortening of soft tissue and a partial loss of range of spinal motion (1). Several recommendations promoting the spinal flexibility in elderly people are based on stretching programs that include static and ballistic exercises and PNF techniques (2). Several studies showed that specific training programs could improve body balance (3), bodyweight distribution on feet (4), muscle strength and flexibility (5) in elders. In particular, Imagama et al. (2011) show…

Effects of a dynamic stretching warm-up on functional movement patterns in female hip-hop dancers

2022

Background: A large percentage of dancers suffer an injury to their musculoskeletal system at least once in their careers, as well as from pain caused by overloading or overtraining this system. A high frequency of injuries has been observed in hip-hop dancers. Before each workout, there should be a solid warm-up and stretching period. The lack of these two important elements increases the risk of injury. Aim of the study: This study aimed to examine the effects of dynamic stretching warm-ups on fundamental movement patterns in female hip-hop dancers. Material and methods: This study included 14 hip-hop female dancers, aged 15–17. Dancers participated in 6 weeks of dynamic stretching warm-u…

Effects of between-set interventions on neuromuscular function during isokinetic maximal concentric contractions of the knee extensors

2011

The presents study investigated the effects of between-set interventions on neuromuscular function of the knee extensors during six sets of 10 isokinetic (120°·s(-1)) maximal concentric contractions separated by three minutes. Twelve healthy men (age: 23.9 ± 2.4 yrs) were tested for four different between-set recovery conditions applied during two minutes: passive recovery, active recovery (cycling), electromyostimulation and stretching, in a randomized, crossover design. Before, during and at the end of the isokinetic session, torque and thigh muscles electromyographic activity were measured during maximal voluntary contractions and electrically-evoked doublets. Activation level was calcul…
