Summary: A new method for detecting balance impairments in older adults is proposed by analyzing the frequency components, sensory inputs, reaction time, motor functions, and Fall-related Concerns (FrC) of their Center of Pressure (CoP) trajectory. By using Discrete Wavelet Transform (DWT), three distinct groups of subjects were revealed, with group 1 relying on very low frequency scales, group 2 showing the broadest use of frequency scales and lowest FrC, and group 3 relying on higher frequency scales. This study provides a cost-effective method for identifying individuals at risk and developing interventions to prevent falls.

Summary: This study aimed to investigate the effect of adding inspiratory muscle training (IMT) to whole body vibration (WBV) on functional outcomes, balance, and physical performance in pre-frail older women. Results showed that adding IMT to WBV improved 6-minute walk distance, balance, and functional mobility, but had no significant effect on handgrip strength and muscle metabolism.

Summary: This study aims to examine the effectiveness of resistance training on resilience among Chinese older adults in Hong Kong. The three-group, double-blinded, randomized controlled trial will assess the interventions on resilience, functional fitness, and health related quality of life. It is expected that resistance training may be more promising or even superior to aerobic training in improving resilience among older adults.

Summary: This research introduces a dual adaptive training approach (DAT) that helps photonic neural networks (PNNs) adapt to and maintain their performance under large-scale systematic errors. The results demonstrate that DAT successfully trains large-scale PNNs and achieves high classification accuracies, outperforming existing training approaches.

Summary: The study found that muscle loss with aging is region-specific for some muscles and uniform for others. Equivalent strength training volume at moderate or high intensities increased muscle volume with no differences in muscle volume gains for old men. These data suggest that physical exercise at moderate intensity (55 to 60% of one repetition maximum) can reverse the aging related loss of muscle mass.

Summary: This study aimed to evaluate the effects of 12 weeks of resistance training with progressive intensity on factors associated with sarcopenia in older individuals. The results showed that resistance training can improve physical performance and muscular strength, but it does not significantly affect muscle mass index and walking speed.

Summary: Inactivity can lead to muscle weakness, which is caused by chronically increased levels of reactive oxygen species (ROS). Surprisingly, high-intensity interval training (HIIT) with high ROS production can have positive effects on conditions with chronically increased ROS. In this study, young male volunteers underwent 3 weeks of leg unloading followed by 3 weeks of resistance training, with or without all-out cycling HIIT. Muscle thickness and contractile function were assessed. The results showed that both the Ctrl and HIIT groups fully restored muscle thickness and function after the training period, suggesting that resistance training alone can restore the effects of inactivity.

Summary: This study aimed to test the effects of resistance training (RT) and muscle microstimulation on mood and physical recovery in healthy men. Results showed that microstimulation increased self-ratings of feeling well-rested and sociable, and reduced exercise-induced exhaustion. This finding is important for both professional athletes and non-professionals seeking optimal results after a workout.

Summary: Mechanical loading is a significant risk factor for low-back pain, and real-time estimation of L5S1 joint moment can help decrease the loading. This study compared two approaches and found that a simplified inverse dynamics model performed better in terms of practical feasibility and minimizing sensor use.

Summary: The analysis of single motor unit (SMU) activity is crucial for understanding the neural strategies controlling muscle force. Traditionally, this analysis has been done invasively through intramuscular electromyography (EMG), but recent advances in signal processing techniques have enabled the identification of SMU activity in high-density surface electromyography (HDsEMG) recordings.

Summary: Power for human walking primarily comes from ankle and hip muscles. Adding a 'passive' hip spring to bipedal models can improve efficiency compared to using only push-off impulse, but the energetic costs of hip spring are not well studied. This study simulated a flat-feet model walking at different speeds and found that asymmetric hip actuation can reduce the metabolic cost of transport (MCOT) relative to ankle actuation by up to 6%, but only at medium speeds. Coordinating ankle actuation, hip flexion, and retraction actuation can help reduce MCOT.

Summary: This study examined hamstring muscle activity during high-speed running, specifically looking at activity distribution, relative contribution, and joint angles. Muscle activity was measured using electromyography in male basketball players. The results showed that hamstring muscles were most active in the late-swing phase, with the semimembranosus being the most active and the semitendinosus being the least active. There were no significant differences in joint angles at the instant of peak muscle activity.

Summary: Features of lower limb bone geometry are important for movement kinematics and clinical outcomes. However, the effects of adulthood physical activity on lower limb geometry and their associations with muscle function are relatively unexplored. This study found that trained individuals had higher femoral frontal bowing and older individuals had greater lateral bowing, but lower limb geometry was not associated with muscle function.

Summary: Understanding the mechanisms humans use to stabilize walking is crucial for predicting falls in the elderly. Two potential mechanisms, foot placement control and ankle push-off control, have been identified to stabilize gait in the anterior-posterior direction. It is unknown whether the latter mechanism is employed in steady-state walking. This study found that foot placement errors in steady-state walking were correlated to ankle push-off torque, suggesting that humans use a push-off strategy to correct foot placement errors.

Summary: This systematic review found that combined lifestyle interventions are not superior to usual care for improving physical functioning, relieving pain, and improving lifestyle outcomes in overweight or obese individuals with persistent low-back pain. However, these interventions are likely to be more cost-effective in terms of healthcare, medication, and absenteeism costs compared to usual care.

Summary: This study aimed to examine the effect of a sleeve knee brace on knee biomechanics during stair negotiation in patellofemoral joint osteoarthritis patients. The findings showed that the knee brace significantly reduced the maximal flexion angle, adduction angle, sagittal and frontal range of motion, and sagittal peak extension moment during stair ascent. During stair descent, the knee brace significantly reduced the maximal flexion angle and total sagittal range of motion compared to control.

Summary: This study investigates the effects of chronic low-back pain (CLBP) and pain-related cognitions on the impact of mechanical perturbations on trunk movement, as well as the associations between these perturbation effects and movement precision. The findings suggest that negative pain-related cognitions can increase resistance to perturbations, but at the expense of movement precision.

Summary: Trunk extensor muscle fatigue is characterized by a decline in spectral content of surface electromyography, which primarily reflects a decrease in average motor unit action potential conduction velocity. This study found that the linear rate of change in conduction velocity was strongly correlated with trunk extensor muscle endurance time, whereas the correlation between the linear rate of change in spectral measures and endurance time was lower or non-existent. These findings provide guidance for monitoring the development of trunk extensor muscle fatigue using electromyography.
