Patterns of responses and time-course of changes in muscle size and strength during low-load blood flow restriction resistance training in women.
The purpose of this investigation was to examine the individual and composite patterns of responses and time-course of changes in muscle size, strength, and edema throughout a 4 week low-load blood flow restriction (LLBFR) resistance training intervention.. Twenty recreationally active women (mean ± SD; 23 ± 3 years) participated in this investigation and were randomly assigned to 4 weeks (3/week) of LLBFR (n = 10) or control (n = 10) group. Resistance training consisted of 75 reciprocal isokinetic forearm flexion-extension muscle actions performed at 30% of peak torque. Strength and ultrasound-based assessments were determined at each training session.. There were quadratic increases for composite muscle thickness (R. These findings suggested that the increases in muscle thickness for the LLBFR group were not associated with edema and changes in echo intensity should be examined on a subject-by-subject basis. Furthermore, LLBFR forearm flexion-extension resistance training elicited real increases in muscle size during the very early phase of training that occurred prior to real increases in muscle strength.

Computer-guided versus free-hand placement of immediately loaded dental implants: 1-year post-loading results of a multicentre randomised controlled trial.
To compare planning and patient rehabilitation using a 3D dental planning software and dedicated surgical guides with conventional rehabilitation of partially or fully edentulous patients using flapless or mini-flap procedures and immediate loading.. Fifty-one fully or partially edentulous patients requiring at least 2 implants to be restored with a single prosthesis, having at least 7 mm of bone height and 4 mm in bone width, had their implant rehabilitation planned on three-dimensional (3D) cone beam computed tomography (CBCT) scans using a dedicated software. Afterwards they were randomised according to a parallel group study design into two arms: computer-guided implant placement aided with templates (computer-guided group) versus conventional implant placement without templates (conventional group) in three different centres. Implants were to be placed flapless and loaded immediately; if inserted with a torque over 35 Ncm with reinforced provisional prostheses, then replaced, after 4 months, by definitive prostheses. Outcome measures, assessed by masked assessors were: prosthesis and implant failures, complications, peri-implant bone level changes, number of treatment sessions, duration of treatment, post-surgical pain and swelling, consumption of pain killers, treatment time, time required to solve complications, additional treatment cost, patient satisfaction. Patients were followed up to 1 year after loading.. Twenty-six patients were randomised to the conventional treatment and 25 to computerguided rehabilitation. No patient dropped out. One provisional prosthesis failed, since one of the two supporting implants failed 11 days after implantation in the conventional group (P = 1.0). Four patients of the conventionally loaded groups experienced one complication each, versus five patients (6 complications) in the computer-guided group (P = 0.726). There were no statistically significant differences between the two groups for any of the tested outcomes with the exception of more postoperative surgical pain (P = 0.002) and swelling (P = 0.024) at conventionally treated patients.. When treatment planning was made on 3D CBTC scan using a dedicated software, no statistically significant differences were observed between computer-guided and a free-hand rehabilitations, with the exception of more postoperative pain and swelling at sites treated freehand because more frequently flaps were elevated.

Acute changes in muscle thickness, edema, and blood flow are not different between low-load blood flow restriction and non-blood flow restriction.
The purpose of the present study was to examine the acute changes in muscle swelling (as assessed by muscle thickness and echo intensity) and muscle blood flow associated with an acute bout of low-load blood flow restriction (LLBFR) and low-load non-blood flow restriction (LL) exercise. Twenty women (mean ± SD; 22 ± 2years) volunteered to perform an acute exercise bout that consisted of 75 (1 × 30, 3 × 15) isokinetic, reciprocal, concentric-only, submaximal (30% of peak torque), forearm flexion and extension muscle actions. Pretest, immediately after (posttest), and 5-min after (recovery) completing the 75 repetitions, muscle thickness and echo intensity were assessed from the biceps brachii and triceps brachii muscles and muscle blood flow was assessed from the brachial artery. There were no between group differences for any of the dependent variables, but there were significant simple and main effects for muscle and time. Biceps and triceps brachii muscle thickness increased from pretest (2.13 ± 0.39 cm and 1.88 ± 0.40 cm, respectively) to posttest (2.58 ± 0.49 cm and 2.17 ± 0.43 cm, respectively) for both muscles and remained elevated for the biceps brachii (2.53 ± 0.43 cm), but partially returned to pretest levels for the triceps brachii (2.06 ± 0.41 cm). Echo intensity and muscle blood flow increased from pretest (98.0 ± 13.6 Au and 94.5 ± 31.6 ml min Topics: Arm; Edema; Exercise; Female; Humans; Muscle, Skeletal; Torque | 2021 |
Can Hip Joint Position affect Quadriceps Muscle Responses during Knee Extension Exercise?
This study investigated the acute effects of seated and supine knee extension exercise on muscle swelling, torque, and work output. Twelve resistance-trained men performed two isokinetic concentric-only knee-extension training protocols at different hip positions in a counter-balanced order. They completed the knee extension exercise in the seated (hip angle at 85°) and supine (hip angle at 180°) positions. The torque and work output were assessed during each set. Moreover, muscle thickness of the middle and proximal vastus lateralis and rectus femoris were evaluated before and after each protocol and used as an indicator of muscle swelling. Middle rectus femoris and proximal vastus lateralis thickness increased significantly (p=0.01) with no difference between exercise variations. However, the middle vastus lateralis thickness increased (p=0.01) only after the seated knee extension exercise (~7%). Knee extensors' peak torque and work output were approximately 8% higher (p=0.04) in the seated when compared to the supine hip position. There was a similar decrease in torque and work output throughout both protocols (p=0.98). In conclusion, seated knee extension exercises produced greater torque, work output, and muscle swelling in the vastus lateralis when compared to the supine knee extension exercise.

Impact of Fatiguing, Submaximal High- vs. Low-Torque Isometric Exercise on Acute Muscle Swelling, and Echo Intensity in Resistance-Trained Men.
Muddle, TWD, Magrini, MA, Colquhoun, RJ, Luera, MJ, Tomko, PM, and Jenkins, NDM. Impact of fatiguing, submaximal high- vs. low-torque isometric exercise on acute muscle swelling, and echo intensity in resistance-trained men. J Strength Cond Res 33(4): 1007-1019, 2019-To evaluate the effects of repeated, fatiguing isometric knee extension contractions performed at high-torque (HT) vs. low-torque (LT) maximal voluntary isometric contraction (MVIC) on acute muscle swelling, and echo intensity (EI) of the rectus femoris (RF) and vastus lateralis (VL) muscles in resistance-trained males. Twenty-two resistance-trained men performed either HT (70% MVIC) or LT (30% MVIC) isometric contractions to fatigue on separate days. Before and after exercise, muscle cross-sectional area (mCSA) and EI of the RF and VL were assessed through ultrasound. Muscle cross-sectional area and EI (collapsed across muscle) increased similarly after HT (mean ± 95% confidence interval: mCSAΔ: 3.52 ± 0.52 cm; EIΔ: 4.58 ± 1.65 au) and LT (mCSAΔ: 3.61 ± 0.59 cm; EIΔ: 3.30 ± 1.36 au) exercise. No relationships between mCSAΔ and time to task failure (TTF), normalized MVIC, or the tension-time integral were observed during either HT or LT exercise. During both conditions, EIΔ was related to TTF (HT: r = 0.44; LT: r = 0.66) and normalized MVIC (HT: r = -0.60; LT: r = -0.57). These results suggest that acute muscle swelling and increased EI observed in response to intermittent, submaximal, fatiguing isometric exercise are similar for the RF and VL and are not dependent on the torque-level or tension-time integral when exercise is performed to failure. Factors such as the duration of time performing exercise and relative muscle strength may influence the magnitude of change in EI, but not acute muscle swelling, during intermittent fatiguing isometric exercise.

Non-Uniformity of Elbow Flexors Damage Induced by an Eccentric Protocol in Untrained Men.
Muscle structure disorganization is a consequence of intense eccentric contractions, with symptoms that characterize exercise-induced muscle damage (EIMD). To date, few studies have described EIMD parameters at different muscle sites. The aim of the present study was to analyse indirect markers of EIMD at two elbow flexors sites over three days. Eleven healthy untrained men were submitted to a session of three sets of 10 eccentric elbow flexion repetitions on an isokinetic dynamometer. The isometric peak torque (PT), muscle soreness, elbow flexors oedema, (normalized muscle thickness [MT]) and echo-intensity (EI) were measured. There was a significant decrease in PT immediately after (Post) and 10 min, 24 h, 48 h and 72 h after intervention compared to that at baseline (p < 0 .05). MT% increased after 72 h compared with that immediately, 10 min and 24 h after intervention (p < 0.05). No statistical changes were observed in muscle soreness and oedema between the two muscle sites. With respect to EI%, significant differences were observed for the 24 h, 48 h and 72 h measures compared with those of the Post, 10 min and 24 h measures for both muscle sites; at the distal site, EI% was significantly higher than at the proximal site for measures after 24 h (p < 0.05). The presence of differences in EI% 24 h after eccentric training on distal sites of elbow flexors indicates non-uniform EIMD in this region.

Neuromuscular Adaptations to Work-matched Maximal Eccentric versus Concentric Training.
It is unclear whether the superiority of eccentric over concentric training on neuromuscular improvements is due to higher torque (mechanical loading) achievable during eccentric contractions or due to resulting greater total work.. This study aimed to examine neuromuscular adaptations after maximal eccentric versus concentric training matched for total work.. Twelve males conducted single-joint isokinetic (180°·s) maximal eccentric contractions of the knee extensors in one leg (ECC-leg) and concentric in the other (CON-leg), 6 sets per session (3-5 sets in the initial 1-3 sessions), 2 sessions per week for 10 wk. The preceding leg performed 10 repetitions per set. The following leg conducted the equivalent volume of work. In addition to peak torque during training, agonist EMG and MRI-based anatomical cross-sectional area (ACSA) and transverse relaxation time (T2) at midthigh as reflective of neural drive, hypertrophy, and edema, respectively, were assessed weekly throughout the training period and pre- and posttraining. Whole muscle volume was also measured pre- and posttraining.. Torque and EMG (in trained contraction conditions) significantly increased in both legs after week 1 (W1) and week 4 (W4), respectively, with a greater degree for ECC-leg (torque +76%, EMG +73%: posttraining) than CON-leg (+28%, +20%). ACSA significantly increased after W4 in ECC-leg only (+4%: posttraining), without T2 changes throughout. Muscle volume also increased in ECC-leg only (+4%). Multiple regression analysis revealed that changes (%Δ) in EMG solely explained 53%-80% and 30%-56% of the total variance in %Δtorque through training in ECC-leg and CON-leg, respectively, with small contributions (+13%-18%) of %ΔACSA for both legs.. Eccentric training induces greater neuromuscular changes than concentric training even when matched for total work, whereas most of the strength gains during 10-wk training are attributable to the increased neural drive.

Hamstring strength and morphology progression after return to sport from injury.
Hamstring strain reinjury rates can reach 30% within the initial 2 wk after return to sport (RTS). Incomplete recovery of strength may be a contributing factor. However, relative strength of the injured and unaffected limbs at RTS is currently unknown.The purpose was to characterize hamstring strength and morphology at the time of RTS and 6 months later.. Twenty-five athletes who experienced an acute hamstring strain injury participated after completion of a controlled rehabilitation program. Bilateral isokinetic strength testing and magnetic resonance imaging (MRI) were performed at RTS and 6 months later. Strength (knee flexion peak torque, work, and angle of peak torque) and MRI (muscle and tendon volumes) measures were compared between limbs and over time using repeated-measures ANOVA.. The injured limb showed a peak torque deficit of 9.6% compared to the uninjured limb at RTS (60°·s, P < 0.001) but not 6 months after. The knee flexion angle of peak torque decreased over time for both limbs (60°·s, P < 0.001). MRI revealed that 20.4% of the muscle cross-sectional area showed signs of edema at RTS with full resolution by the 6-month follow-up. Tendon volume of the injured limb tended to increase over time (P = 0.108), whereas muscle volume decreased between 4% and 5% in both limbs (P < 0.001).. Residual edema and deficits in isokinetic knee flexion strength were present at RTS but resolved during the subsequent 6 months. This occurred despite MRI evidence of scar tissue formation (increased tendon volume) and muscle atrophy, suggesting that neuromuscular factors may contribute to the return of strength.

Computer-guided flapless placement of immediately loaded dental implants in the edentulous maxilla: a pilot prospective case series.
The aim of this case series was to evaluate the Procera Software v1.6 and the surgical templates for flapless implant placement and immediate loading in atrophic fully edentulous maxillae.. The Procera Software was used to plan the exact position of the implants, and surgical templates were made to guide flapless implant placement. To allow for immediate loading, implants had to be placed with an insertion torque > 30 Ncm. Provisional cross-arch prostheses, produced before surgery using the software planning, were delivered immediately after implant placement, and replaced by final restorations after 6 months. Outcome measures were: prosthetic and implant failures, complications, post-operative pain and swelling, consumption of analgesics, and patient satisfaction. The followup stopped at 8 months post-loading.. Thirteen consecutive patients with atrophic maxillae were treated with 89 implants (6 to 8 implants per patient). Two flaps had to be elevated in two patients. One template fractured during surgery. Three implants in two patients were not loaded immediately. In four patients, impressions had to be taken to fit the provisional prostheses onto the implants. Five implants failed in four patients. One patient dropped out, due to financial reasons, with the provisional prosthesis still in function. Eight months after loading, all prostheses were successful and 11 out of 12 patients reported their quality of life and lifestyle had improved.. This software-based treatment planning may be useful in planning and treating challenging cases such as flapless implant placement and immediate loading of maxillary cross-arch bridges, but a learning curve is necessary.

Acute physiological effects of exhaustive whole-body vibration exercise in man.
Vibration exercise (VE) is a new neuromuscular training method which is applied in athletes as well as in prevention and therapy of osteoporosis. The present study explored the physiological mechanisms of fatigue by VE in 37 young healthy subjects. Exercise and cardiovascular data were compared to progressive bicycle ergometry until exhaustion. VE was performed in two sessions, with a 26 Hz vibration on a ground plate, in combination with squatting plus additional load (40% of body weight). After VE, subjectively perceived exertion on Borg's scale was 18, and thus as high as after bicycle ergometry. Heart rate after VE increased to 128 min-1, blood pressure to 132/52 mmHg, and lactate to 3.5 mM. Oxygen uptake in VE was 48.8% of VO2max in bicycle ergometry. After VE, voluntary force in knee extension was reduced by 9.2%, jump height by 9.1%, and the decrease of EMG median frequency during maximal voluntary contraction was attenuated. The reproducibility in the two VE sessions was quite good: for heart rate, oxygen uptake and reduction in jump height, correlation coefficients of values from session 1 and from session 2 were between 0.67 and 0.7. Thus, VE can be well controlled in terms of these parameters. Surprisingly, an itching erythema was found in about half of the individuals, and an increase in cutaneous blood flow. It follows that exhaustive whole-body VE elicits a mild cardiovascular exertion, and that neural as well as muscular mechanisms of fatigue may play a role.
