Squat Exercise

Background and purpose: Knee injuries are common among female softball players, and the stability of the lower extremities and the strength of the knee are essential factors for them. The purpose of this study was to investigate the effect of Kinesio taping with squat exercise (KTSE) on lower extremity muscle activity, muscle strength, muscle tone, and dynamic stability of softball players. Methods: In this study, 40 softball players were randomly assigned to the KTSE group and sham taping with squat exercise (SKTSE) group. All subjects were tested three times a week for 6 weeks, i.e., for a total of 18 times. To evaluate the lower-extremity muscle activity, muscle strength, and muscle tone of the lower extremities, as well as dynamic stability, we used Noraxon Mini DTS, a digital muscular meter from JTech Medical, MyotonPRO, and the side hop test (a clinical evaluation method), respectively. These items were measured before the experiment and 6 weeks after the start of the experiment. Results: Both groups showed significant differences in lower-extremity muscle activity, muscle strength, muscle tone, and dynamic stability (p < 0.05). After the experiment, significant effects on lower-extremity muscle activity, muscle strength, muscle tone, and dynamic stability were observed in the KTSE group compared with in the SKTSE group (p < 0.05). Conclusions: KTSE did not have a negative effect on all items of the functional performance test. KTSE improved lower-extremity muscle activity, muscle strength, muscle tone, and dynamic stability.

Objective In this study, the aim was to evaluate the lower extremity muscle strength in patients with chronic venous insufficiency using an isokinetic dynamometer. Methods The study comprised a group of 36 lower extremities of 23 patients diagnosed with chronic venous insufficiency and a control group of 40 lower extremities of 20 patients who did not have chronic venous insufficiency. In the diagnosis and evaluation of chronic venous insufficiency, photoplethysmography was used to evaluate the venous return circulation time. Visual Analog Scale scoring was applied to define the level of pain of the patients. Muscle strength measurements were made in all the lower extremities by using an isokinetic dynamometer. Results A statistically significant difference was detected between the groups in terms of the muscle strength parameters in the ankle plantar flexion, and knee flexor and extensor muscles. However, no statistically significant difference was found between the groups in the ankle dorsiflexion muscle strength parameters. A significant difference was determined in the ratio of ankle dorsiflexion/plantar flexion muscle strength between the mild, moderate and severe venous insufficiency groups. A statistically considerable negative correlation was found between the Visual Analog Scale scores and the photoplethysmography results. According to the Visual Analog Scale results, as the degree of venous insufficiency increased, so did the level of pain. Conclusion Impaired lower extremity muscle strength was observed in chronic venous insufficiency patients. Although the current study was consistent with literature in respect of impaired calf muscle strength, this finding was also seen in the thigh muscles. Furthermore, we concluded that if venous insufficiency becomes more severe, impaired calf muscle strength becomes more evident.

Background: Sensory motor impairment, the most common neuromuscular condition in stroke patients, often contributes to muscle weakness and imbalance. Objective: The purpose of this research was to investigate the effects of cognitive sensory-motor training (CSMT) on the muscle strength and balance ability in post-stroke patients. Methods: Thirty-five participants after stroke were randomly assigned to the CSMT (n = 17) or control group (n = 18). All participants received 30 min of training each time, five times per week, for six weeks. Lower extremity muscle strength of tibialis anterior (LEMTA) was evaluated using a digital muscular dynamometer. The Medical Research Council (MRC) scale was used to evaluate muscle strengths of the hip joint, knee joint, and ankle joint. For balance ability test, the center of pressure (COP) movement distance and limited of stability (LOS) were measured using BioRescue. Results: LEMTA, MRC scale, balance ability were significantly more improved in the CSMT group than in the control group (p < 0.05). Conclusions: Our findings indicate that CSMT is beneficial and effective for improving muscle strength of the lower extremity and balance ability of post-stroke patients.

Abstract Background The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling. Methods We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test’s participate. Results A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group. Discussion Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise. Conclusion Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.

Abstract Background The risk of adverse events associated with peritoneal dialysis (PD) in elderly patients has not been thoroughly investigated. The purpose of this study was to assess the association between physical function and hospitalization in elderly PD patients. Methods This is a single-center prospective observational cohort study. Thirty-three aged patients (74.8 ± 5.9 years) participated in a 6-min walk distance, short physical performance battery (SPPB), lower extremity muscle strength, and 10-m walk speed. All subjects were followed until hospitalization to the end of the follow-up period. Results The 6-min walk distance was 332 ± 112.5 m; SPPB was 11 (8.3–12) points; the lower extremity muscle strength was 36.6 ± 9.6%; 10-m walk speed was 1.1± 0.2 m/s. During the follow-up, 19 patients (57.5%) were hospitalized. In the Kaplan-Meier survival analysis and log-rank test, a lower 6-min walk distance and PD vintage were significantly associated with hospitalization (p<0.05). After adjustment for PD vintage in Cox proportional analysis, the 6-min walk distance remained associated with hospitalization (95% confidence interval, 0.98–0.99). Conclusion Lower exercise tolerance assessed by the 6-min walk distance was significantly associated with hospitalization in elderly PD patients. Our findings indicate that measurement and intervention of exercise intolerance are essential to predict the clinical outcomes of elderly PD patients. Trial registration This study was prospectively registered at inception in the UMIN Clinical Trials Registry under identification number UMIN000038405.

Context:Muscle activation during aquatic treadmill (ATM) running has not been examined, despite similar investigations for other modes of aquatic locomotion and increased interest in ATM running.Objectives:The objectives of this study were to compare normalized (percentage of maximal voluntary contraction; %MVC), absolute duration (aDUR), and total (tACT) lower-extremity muscle activity during land treadmill (TM) and ATM running at the same speeds.Design:Exploratory, quasi-experimental, crossover design.Setting:Athletic training facility.Participants:12 healthy recreational runners (age = 25.8 ± 5 y, height = 178.4 ± 8.2 cm, mass = 71.5 ± 11.5 kg, running experience = 8.2 ± 5.3 y) volunteered for participation.Intervention:All participants performed TM and ATM running at 174.4, 201.2, and 228.0 m/min while surface electromyographic data were collected from the vastus medialis, rectus femoris, gastrocnemius, tibialis anterior, and biceps femoris.Main Outcome Measures:For each muscle, a 2 × 3 repeated-measures ANOVA was used to analyze the main effects and environment–speed interaction (P ≤ .05) of each dependent variable: %MVC, aDUR, and tACT.Results:Compared with TM, ATM elicited significantly reduced %MVC (−44.0%) but increased aDUR (+213.1%) and tACT (+41.9%) in the vastus medialis, increased %MVC (+48.7%) and aDUR (+128.1%) in the rectus femoris during swing phase, reduced %MVC (−26.9%) and tACT (−40.1%) in the gastrocnemius, increased aDUR (+33.1%) and tACT (+35.7%) in the tibialis anterior, and increased aDUR (+41.3%) and tACT (+29.2%) in the biceps femoris. At faster running speeds, there were significant increases in tibialis anterior %MVC (+8.6−15.2%) and tACT (+12.7−17.0%) and rectus femoris %MVC (12.1−26.6%; swing phase).Conclusion:No significant environment–speed interaction effects suggested that observed muscle-activity differences between ATM and TM were due to environmental variation, ie, buoyancy (presumed to decrease %MVC) and drag forces (presumed to increase aDUR and tACT) in the water.
