“…Adding WBV to exercise training was found to improve muscle strength, balance, and reduce incidence of falls among older adults (Merriman and Jackson, 2009;Lam et al, 2012;Lau et al, 2011). These improvements were mainly attributed to the augmented muscle activity during WBV stimulation (Liao et al, 2014;Hazell et al, 2007;Di Giminiani et al, 2015). The increase in muscle activity is achieved via inducing involuntary rapid changes in muscle length, thereby triggering the tonic vibration reflex (Hazell et al, 2007).…”

Objective: To evaluate the effects of whole-body vibration (WBV) added to a routine activity program on lower limb strength, balance, and mobility among community-dwelling individuals with mild or moderate dementia, compared with the routine program alone. Methods: Fifty-four older adults (40 women; mean (SD) age: 79.8 (6.1) years) with mild or moderate dementia were recruited from two daycare centers. The participants were randomly allocated to undergo a routine day activity program combined with WBV training (WBV at 30 Hz, 2-mm peakto-peak amplitude) or the routine program only without WBV for 9 weeks (18 sessions). The primary outcome was functional mobility, measured using the timed up-and-go test. The following secondary outcomes were evaluated: Berg Balance Scale, Tinetti balance assessment, time to complete 5 repetitions of sit-to-stand, Quality of Life in Alzheimer's disease questionnaire, and Activities-specific Balance Confidence scale. The attendance rate and incidence of adverse events were also recorded. Results: The attendance rate for the training was high (86.0%). The incidence of adverse events was low, with only two of the 27 participants in the WBV group reporting mild knee pain. While significant improvement in timed up-and-go, Berg Balance Scale, and Tinetti balance score was found in both groups, none of the outcomes demonstrated a significant group by time interaction. Conclusions: WBV training is feasible and safe to use with people with mild or moderate dementia. However, it did not lead to further improvement in physical function and quality of life than the usual activity program provided at the daycare centers.

SummaryThe proper design and implementation of a study as well as a balanced and well-supported evaluation and interpretation of its main findings are of crucial importance when reporting and disseminating research. Also accountability, funding acknowledgement and adequately declaring any conflict of interest play a major role in science. Since the Muscles, Ligaments and Tendons Journal (MLTJ) is committed to the highest scientific and ethical standards, we encourage all Authors to take into account and to comply, as much as possible, to the contents and issues discussed in this official editorial. This could be useful for improving the quality of the manuscripts, as well as to stimulate interest and debate and to promote constructive change, reflecting upon uses and misuses within our disciplines belonging to the field of "Clinical and Sport -Science Research". KEY WORDS: best practice, conflict of interest, design, experimental approach, ethical standard, statement, evidence-based medicine.

“…Physicians and sports practitioners use squat movement during rehabilitation to train and empower leg muscles (2). It is believed that exercises such as squat that move in the closed kinetic chain (the movements that distal extremity is fixed on the ground) are more effective in improving the strength of the knee muscles (3,4). In this regard, Giminiyani et al reported that closed-chain movements, reduce the risk of injury and lead to joint stability due to increased contraction around the joint (3).…”

Objectives: Squat is known as a common and functional exercise for strengthening the lower limb muscles. However, researchers put it in the category of exercises with high risk of injury. So, the purpose of this study was to investigate the effect of three different techniques of squat on electromyographic response of trunk and lower limb muscles in athletes and non-athletes. Methods: Twenty subjects including 10 amateurs and 10 professional athletes ranging from 22 to 27 years old participated in the study. Three different techniques of squat were analyzed using electromyography (EMG) assessment. EMG was recorded from vastus lateralis, vastus medialis, semitendinosus, biceps femoris, adductor longus, transversus abdominis and multifidus muscles during squatting. Independent-Samples t-test and multivariate analysis of variance (MANOVA) were used to analysis the data. Results:The finding indicated that there was no significant difference between the two groups in all of the muscles activities (P ≤ 0.05). During lunge squat, the semitendinosus had more muscle activity in comparison with two other techniques (P = 0.023). However, the transversus abdominis and multifidus muscles revealed a less significant muscle activity during lunge squat (P = 0.001). Conclusions: Given the results of this study indicating that lunge squat is more suitable for strengthening the semitendinosus muscle and the parallel and plie squat technique seem to be better suited to strengthen the transversus abdominis and multifidus muscles, it can be argued that these movements can be used to strengthen the hamstring and spinal muscles respectively.
