Summary: This study aimed to investigate the changes in muscle architecture of quadriceps femoris constituents with sensor electrodes placed over VL and VM motor points during a neuromuscular electrical stimulation session. The results showed no difference in the muscle architecture changes when the electrodes were placed on VL and VM motor points. Therefore, clinicians can choose either VL or VM motor points for sensor electrode positioning and expect similar muscle architecture adaptation.

Summary: After stratification by sex and resting lung function, quadriceps muscle strength and endurance were significantly associated with exercise capacity in COPD patients, with endurance being a more important determinant than strength. This underscores the importance of evaluating both quadriceps muscle strength and endurance in all COPD patients.

Summary: This study compared the effectiveness of a home-based NMES program to a sham-NMES program in patients following ACL reconstruction. The results showed that a 6-week home-based NMES program applied to the quadriceps of the nonoperative side prevented knee extensor muscle weakness 6 months after surgery.

Summary: The study found that respiratory muscle strength, maximal exercise capacity, and fatigue were adversely affected in colorectal cancer survivors. Cancer treatment may lead to loss of muscle strength, impaired energy metabolism, and oxygen transmission, resulting in decreased exercise capacity, respiratory muscle strength, and increased fatigue.

Summary: This study investigated the effects of different durations of muscle cooling on strength and endurance. The results showed that 5, 10, and 20-minute cold applications did not affect isokinetic muscle strength and endurance. However, the strength ratio between agonist-antagonist muscles may change with different duration cold applications.

Summary: This study longitudinally examined the quadriceps torque complexity in individuals who underwent ACL reconstruction after ACL injury. The results showed a decrease in quadriceps peak torque and an increase in torque complexity in the involved limb compared to the uninvolved limb. These findings suggest that ACL reconstruction not only leads to a decline in quadriceps strength, but also compromises the quality of quadriceps muscle contraction, which may contribute to impaired physical function in individuals following ACL reconstruction.

Summary: This study aimed to explore respiratory muscle fatigability (RMF) in patients with Spinal Muscular Atrophy (SMA). The results showed that there was a dose-dependent increase in RMF in SMA patients during the Respiratory Endurance Test (RET). Additionally, the fatigability response in SMA patients exhibited large variability in respiratory muscle pressure and a slight increase in perceived fatigue.

Summary: Different functional muscle properties, including quadriceps strength, endurance, and power, are associated with functional exercise capacity in people with COPD. Among these properties, muscle power has the strongest contribution to the 6-minute walking distance and 1-minute sit-to-stand test performance in individuals with COPD.

Summary: This study found that standing core exercise can induce changes in circulatory and hemodynamic responses only when the rotational cadence is set at a faster speed. Fast rotational core exercise can improve cardiac output and femoral blood flow, providing some scientific evidence for the design of exercise programs.

Summary: The use of transcranial direct current stimulation (tDCS) to improve upper limb muscle strength and endurance in healthy individuals is still debated. This article reviews relevant literature and finds that tDCS has no significant effect on upper limb muscle strength but significantly improves upper limb muscle endurance.

Summary: The decrease in quadriceps strength after anterior quadratus lumborum block (AQLB) has not been studied in depth. This prospective study aimed to investigate the incidence of quadriceps weakness after AQLB. The results showed that 13.3% of patients experienced muscle weakness compared with their preoperative baseline, and 30.0% experienced weakness compared with the non-block side. However, all patients were able to walk within 24 hours after surgery, indicating that the weakness was transient.

Summary: Using near-infrared spectroscopy to measure changes in muscle oxygen content can accurately assess the severity of muscle deoxygenation in fibrotic interstitial lung disease patients during exercise. By analyzing the relationship between oxygen uptake and workload, it was found that muscle deoxygenation is worse in fibrotic interstitial lung disease patients during exercise. This simplified approach may be useful in evaluating exercise capacity and interventions in patients with fibrotic interstitial lung disease.

Summary: The study compared the maximal evocable torque (MET) between conventional and wide-pulse neuromuscular electrical stimulation (NMES) at two different frequencies. The results showed that wide-pulse protocols led to greater MET and lower maximal tolerable current intensity compared to conventional NMES.

Summary: This study aimed to determine the physiological predictors of performance in a 166-km trail-running race. The results showed that VO(2)max and velocity at VO(2)max are significant predictors of performance in this race, suggesting that ultratrail runners should focus on developing these qualities to optimize their performance.

Summary: Comparing conventional and wide-pulse NMES, the study found no significant difference in evoked torque. All NMES protocols induced objective fatigability and peripheral alterations, but had no effect on CNS excitability. The results suggest that the chronic effects and treatment effectiveness of conventional and wide-pulse NMES may be comparable.
