Mayo, X, Iglesias-Soler, E, Fariñas-Rodríguez, J, Fernández-del-Olmo, M, and Kingsley, JD. Exercise type affects cardiac vagal autonomic recovery after a resistance training session. J Strength Cond Res 30(9): 2565-2573, 2016-Resistance training sessions involving different exercises and set configurations may affect the acute cardiovascular recovery pattern. We explored the interaction between...

OBJECTIVES To compare the therapeutic effect of two different exercise protocols in athletes with jumper's knee. METHODS Randomised clinical trial comparing a 12 week programme of either drop squat exercises or leg extension/leg curl exercises. Measurement was performed at baseline and after six and 12 weeks. Primary outcome measures were pain (visual analogue scale 1-10) and return to sport....

The purpose of this study was to determine which variables of the range of motion (ROM) and strength of the hip, and ankle are associated with squat depth. In total, 101 healthy subjects (64 males, 37 females) participated in the study. Outcome measures consisted of the ROM of hip flexion, hip internal rotation, external rotation, ankle dorsiflexion with an extended and flexed knee joint, and s...

The purpose of this study was to analyze the validity, reliability, and accuracy of new wearable and smartphone-based technology for the measurement of barbell velocity in resistance training exercises. To do this, 10 highly trained powerlifters (age = 26.1 ± 3.9 years) performed 11 repetitions with loads ranging 50-100% of the 1-Repetition maximum in the bench-press, full-squat, and hip-thrust...

Surface electromyography (sEMG) is used to assess muscle activation during therapeutic exercise, but data are significantly affected by inter-individual variability and requires normalisation of the sEMG signal to enable comparison between individuals. The purpose of this study was to compare two normalisation methods, a maximal method (maximum voluntary isometric contraction (MVIC)) and non-ma...

The Smith machine (SM) (vertical motion of bar on fixed path; fixed-form exercise) and free weights (FWs) (free-form path) are commonly used strength training modes. Exercisers may need to alternate between types of equipment, depending on testing, training, rehabilitation, and/or the exercisers' goals. The purposes of this study were to compare muscle force production for SM and FWs using a 1 ...

inflammation and pain induced by delayed onset muscle soreness (doms) can be induced by eccentric exercise or an unaccustomed activity. the condition can causes problems in exercising and for athletes. the purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. evaluations were made for total antioxidant capacity (tac), mu...

The aim of the present study was to analyze the effect of whole-body vibration on energy expenditure, as well as on exercise intensity, during and immediately after a typical set of exercises for muscle hypertrophy in physically active subjects. Seventeen male university students (mean age 18.3 +/- 0.24 years) volunteered to perform 2 different training exercises: half squat (HS), and half squa...

BACKGROUND Patellar tendinopathy is a common condition affecting the posterior region of the proximal patellar tendon, but the reason for this typical location remains unclear. HYPOTHESIS The posterior region of the proximal patellar tendon is subjected to greater tendinous forces than is the corresponding anterior region. STUDY DESIGN Descriptive laboratory study. METHOD An optic fiber t...

1360-8592/$ see front matter a 2012 Published by Elsevier Ltd. http://dx.doi.org/10.1016/j.jbmt.2012.11.008 We all squat many times throughout the day even if we don’t perform them as exercises. For instance, we squat when we get up from a chair, pick something up from the ground, get in and out of our car, etc. If we hinge too much from our knees or our waist (i.e. spine) then we cause repetit...
