Abstract: Although cryotherapy associated to compression is recommended as immediate treatment after muscle injury, the effect of intermittent sessions of these procedures in the area of secondary muscle injury is not established. This study examined the effect of three sessions of cryotherapy (30 min of ice pack each 2h) and muscle compression (sand pack) in the muscle-injured area. Twenty-four Wistar rats (312 ± 20g) were evaluated. In three groups, the middle belly of tibialis anterior (TA) muscle was injured by a frozen iron bar and received one of the following treatments: a) three sessions of cryotherapy; b) three sessions of compression; c) not treated. An uninjured group received sessions of cryotherapy. Frozen muscles were cross- sectioned (10 μm) and stained for the measurement of injured and uninjured muscle area. Injured muscles submitted to cryotherapy showed the smallest injured area (29.83 ± 6.6%), compared to compressed (39.2 ± 2.8%, p= 0.003) and untreated muscles (41.74 ± 4.0%, p = 0.0008). No difference was found between injured compressed and injured untreated muscles. In conclusion, three intermittent sessions of cryotherapy applied immediately after muscle damage was able to reduce the secondary muscle injury, while only the muscle compression did not provide the same effectiveness

Abstract: objectives: the purpose of this study was to investigate the contributions of functional and morphological factors in the recovery of the quadriceps muscle after anterior cruciate ligament (acl) reconstruction. methods: nine subjects (31.3±5.8 years) underwent eccentric exercise sessions twice a week for 12 weeks. quadriceps muscle function was evaluated using an isokinetic dynamometer (isometric and eccentric peak torque) and electromyography (rms). morphological changes were measured using magnetic resonance imaging. results: the initial evaluation showed a significant deficit in knee extensor torque in the involved limb and significant muscle atrophy along the length of the quadriceps. emg activity was lower in all tested situations. eccentric training significantly increased isokinetic torque (from 199±51 to 240±63, p<0.05, respectively) and quadriceps area, with the greatest hypertrophy in the proximal thigh region (from 169±27 to 189±25.8 cm2, p<0.01). the emg activity of vastus medialis increased after the first six weeks of eccentric training. the increased extensor torque was correlated with quadriceps cross-sectional area (r=0.81, p<0.01) and emg activity (r=0.69, p<0.05). after twelve weeks of training, there was a correlation only between torque and cross-sectional area (r=0.78, p<0.01). conclusions: 1) eccentric training proved to be a potent resource for the quadriceps recovery, both morphologically and functionally, 2) the contributions of functional and morphological factors varied according to the length of training.

Abstract: OBJECTIVES: The purpose of this study was to investigate the contributions of functional and morphological factors in the recovery of the quadriceps muscle after anterior cruciate ligament (ACL) reconstruction. METHODS: Nine subjects (31.3±5.8 years) underwent eccentric exercise sessions twice a week for 12 weeks. Quadriceps muscle function was evaluated using an isokinetic dynamometer (isometric and eccentric peak torque) and electromyography (RMS). Morphological changes were measured using magnetic resonance imaging. RESULTS: The initial evaluation showed a significant deficit in knee extensor torque in the involved limb and significant muscle atrophy along the length of the quadriceps. EMG activity was lower in all tested situations. Eccentric training significantly increased isokinetic torque (from 199±51 to 240±63, p<0.05, respectively) and quadriceps area, with the greatest hypertrophy in the proximal thigh region (from 169±27 to 189±25.8 cm2, p<0.01). The EMG activity of vastus medialis increased after the first six weeks of eccentric training. The increased extensor torque was correlated with quadriceps cross-sectional area (r=0.81, p<0.01) and EMG activity (r=0.69, p<0.05). After twelve weeks of training, there was a correlation only between torque and cross-sectional area (r=0.78, p<0.01). CONCLUSIONS: 1) eccentric training proved to be a potent resource for the quadriceps recovery, both morphologically and functionally, 2) the contributions of functional and morphological factors varied according to the length of training. OBJETIVOS: O propósito deste estudo foi avaliar as contribui es dos fatores funcionais e morfológicos na recupera o da for a muscular do quadríceps femoral após reconstru o do Ligamento Cruzado Anterior (LCA). MéTODOS: Nove indivíduos (31,3±5,8 anos) foram treinados por meio de contra es excêntricas máximas, duas vezes por semana, durante 12 semanas. A fun o do quadríceps foi avaliada pela dinamometria isocinética (pico de torque isométrico e excêntrico) e pela eletromiografia (EMG). As altera es morfológicas foram mensuradas por meio de ressonancia magnética (RNM). Na avalia o inicial, observou-se significativo déficit no torque extensor do joelho do membro acometido, com hipotrofia muscular de todo o quadríceps e redu o na atividade EMG, quando comparado ao membro n o-acometido. RESULTADOS: O treinamento excêntrico produziu aumento no torque excêntrico a 30o/s (de 199±51 Nm para 240±63 Nm, p<0,05) e no volume muscular, sendo que maiores hipertrofias ocorreram na regi o proximal da coxa (de 169±27 para 189±25,8 cm2
Effects of electrical stimulation and stretching on the adaptation of denervated skeletal muscle: implications for physical therapy

Abstract: background: this review will describe the main cellular mechanisms involved in the reduction and increase of myoproteins synthesis commonly associated with muscle atrophy and hypertrophy, respectively. objective: we analyzed the effects of electrical stimulation (es) and stretching exercise on the molecular pathways involved in muscle atrophy and hypertrophy. we also described the main effects and limits of these resources in the skeletal muscle, particularly on the denervated muscle. discussion: recently, our studies showed that the es applied in a similar manner as performed in clinical practice is able to attenuate the increase of genes expression involved in muscle atrophy. however, es was not effective to prevent the loss of muscle mass caused by denervation. regarding to stretching exercises, their mechanisms of action on the denervated muscle are not fully understood and studies on this area are scarce. studies from our laboratory have found that stretching exercise increased the extracellular matrix remodeling and decreased genes expression related to atrophy in denervated muscle. nevertheless, it was not enough to prevent muscle atrophy after denervation. conclusions: in spite of the use of stretching exercise and es in clinical practice in order to minimize the atrophy of denervated muscle, there is still lack of scientific evidence to justify the effectiveness of these resources to prevent muscle atrophy in denervated muscle.

Abstract: background: it is well known that eccentric training increases muscle strength and promotes greater neural activation, and therefore has been used in the recovery of knee extensors. the hypothesis of this study was that there would be a strong correlation between knee extensor torque and functional tests. objectives: to investigate the relationship between knee extensor peak torque and functional tests of agility (runs) and propulsion (hop for distance) after short-term isokinetic eccentric training. methods: twenty healthy and active male undergraduate students (age 22.5±2.1 years; height 1.72±0.10 m; weight 67.8±9.5 kg; body mass index: 22.5±2.0 kg/m2), with no abnormalities or history of injury of the limbs, performed an isokinetic assessment of the knee extensors and flexors and also functional tests before and after isokinetic training, which consisted of 3 sets of 10 mvecs at 30o/s, with 3 minutes of rest between sets, twice a week for 6 weeks. results: the eccentric training increased the extensor peak torque (16, 27 and 17%; p<0.01) and decreased the h/q ratio (10, 20 and 13%; p<0.01) for the isometric and eccentric modes at 30°/s and 120°/s, respectively. it also decreased the time in two of the five agility tests (carioca and pivot diagonal; p<0.01), and increased the distance in the hop tests, for both dominant and non-dominant limbs (p<0.01). conclusions: although the eccentric training led to an increase in extensor peak torques as well as an improvement in most of the functional tests, the hypothesis that a strong correlation would be observed between peak torques and functional tests was not confirmed. article registered in the australian new zealand clinical trials registry (anzctr) under the number 12607000590460.
