In sports science, the use of wearable technology has facilitated the development of new approaches for tracking and assessing athletes' performance. This narrative review rigorously explores the evolution and contemporary state of wearable devices specifically engineered for continuously monitoring lactate levels in sweat, an essential biomarker for appraising endurance performance. Lactate threshold tests have traditionally been integral in tailoring training intensity for athletes, but these tests have relied on invasive blood tests that are impractical outside a laboratory setting.

Thirteen professional female volleyball players were recruited for participation. We performed a randomized single-blind, SHAM-stimulus controlled, and counter-balanced crossover design with two interventions in this study.

Ten young male sprinters performed 100-m sprints following both a high-intensity warm-up (HIW) and a low-intensity warm-up (LIW). Both the HIW and LIW were included in common baseline warm-ups and interventional warm-ups (eight 60-m runs, HIW; 60 to 95%, LIW; 40% alone).

Exergames have been recommended as alternative ways to increase the health benefits of physical exercise. However, energy system contributions (phosphagen, glycolytic, and oxidative) of exergames in specific age groups remain unclear. The purpose of this study was to investigate the contributions of three energy systems and metabolic profiles in specific age groups during exergames.

This study aims to investigate the correlation of foot feature parameters including both MLA and LLA with postural stability.
Method: Thirteen young and healthy subjects participated in this study.
[Purpose] Diabetic peripheral neuropathy can often lead to balance impairment. The spinal reflex is a mechanism that is reportedly important for balance, but it has not been investigated in diabetic peripheral neuropathy patients. Moreover, inhibitory or facilitatory behavior of the spinal reflex-known as presynaptic inhibition-is essential for controlling postural sway.

The unsatisfactory results associated with conventional treatments for symptoms of diabetic peripheral neuropathy (DPN) demonstrate a need for research into alternative therapies. The purpose of this study was to determine the efficacy of whole body vibration therapy (WBV) as a treatment for pain associated with DPN. Participants (n = 8) with painful DPN received three treatment sessions per week for four weeks.

Lower back pain (LBP) is a widespread, expensive, and debilitating problem in Western industrialized countries. Though LBP can be caused by acute injuries, biomechanical discrepancies have also been indicated to cause chronic LBP. A possible link between podiatrical deviations and LBP has been established in the literature; yet, no comprehensive review investigating the effects of foot and ankle deviations on low back pain has been published.

A 64-year-old male had chronic diabetic peripheral neuropathic pain in his both feet for about 2 years. The patient tried multiple pain medications and various interventional pain treatments without significant pain relief.

The purpose of this study was to review possible mechanisms, proposed theories, and physiological changes that occur due to proprioceptive neuromuscular facilitation techniques. Four theoretical mechanisms were identified: autogenic inhibition, reciprocal inhibition, stress relaxation, and the gate control theory.

There has been rising interest in evaluating spinal reflex activity within the clinical population, however no study has yet investigated the reliability of presynaptic inhibition (PI) on patients with diabetic peripheral neuropathy (DPN). Because neuropathy is closely related to central nervous system modification, it is important to understand the mechanism of spinal reflex activity in the DPN population. Therefore, the purpose of the study was to evaluate the reliability of PI in patients with DPN.

While scapular internal rotation has been listed among the forms of scapular dyskinesis there has not been a reliable test documented in the literature that examines this motion.
