Objectives: To investigate the effects of multiple cryotherapy applications after muscle injury on markers of oxidative stress.
Methods: Following cryolesion-induced skeletal muscle injury in rats, ice was applied at the injured site for 30 minutes, three times per day, on the day of injury, and for 2 days after injury. To determine the effect of the cryotherapy treatment on markers of oxidative stress, biochemical analyses were performed 3, 7, and 14 days after injury.
Results: Compared with non-treated animals, cryotherapy reduced dichlorofluorescein at 7 and 14 days post-injury and thiobarbituric acid reactive substances levels at 3 and 7 days post-injury (P < 0.05). Additionally, cryotherapy maintained methyl thiazol tetrazolium reduction levels compared to the control group at all analyzed time points (P > 0.05), whereas non-treated groups demonstrated lower levels than the control group (P < 0.05). Superoxide dismutase activity at 7 and 14 days post-injury and catalase activity at 3 days post-injury were lower in cryotherapy groups compared with non-treated groups (P < 0.05). Cryotherapy prevented the reduction of non-protein thiol levels and maintained within control group level, at 3 days post-injury (P = 0.92).
Discussion: Cryotherapy reduced the production of reactive oxygen species after muscle injury, resulting in an attenuated response of the antioxidant system. These findings suggest that using multiple cryotherapy applications is efficient to reduce oxidative stress.

Purpose Of Review: This review aims to summarise recent evidence on the effects of dietary patterns on the risk of bone fractures and sarcopenia.
Recent Findings: Several dietary patterns have been investigated in relation to musculoskeletal health, including Mediterranean Dietary Patterns (MDP), Dietary Inflammatory Indices, vegetarian and vegan diets. Adherence to 'healthier' dietary patterns appears to be protective against fractures and sarcopenia, with the strongest protective associations found between the MDP and fractures.

Background: Knee valgus loading is thought to be an important contributor to noncontact anterior cruciate ligament (ACL) injuries, but the effects of training programs focusing on decreasing knee valgus loading on lower extremity biomechanics with respect to ACL injury risk remain unclear. Thus, this study aimed to examine the effect of strength training designed to strengthen the medial thigh muscles on lower extremity joint kinematics, kinetics and muscle activity during single-leg landing.
Methods: A total of 35 healthy participants randomly conducted either exercises targeting medial thigh muscles (intervention group) or exercises that did not target specific lower extremity muscles (control group).
A 64-year-old woman suffered a traumatic rupture of the inferior rectus muscle, with the distal segment unrecoverable. An inferior oblique muscle transposition, augmented with a posterior fixation suture, was performed. This modification may have contributed to the surgical outcome.

Background: This observational study investigates the efficacy of combining local muscle vibration (LMV) therapy and kinesiotaping using the McConnell method (KMcCM) in patients with patellofemoral pain syndrome (PFPS). PFPS is a prevalent knee condition characterized by anterior or medial knee pain exacerbated by activities that overload the patellofemoral joint.
Objective: The primary aim of this study was to evaluate the effectiveness of LMV combined with KMcCM in reducing pain and improving function in PFPS patients.
To compare injured and uninjured limb knee extensor and flexor peak torque between youth who experienced a sport-related, traumatic knee joint injury and comparable uninjured youth, at baseline (≤4 months of injury) and semiannually for 2 years. Differences by injury type and sex were also explored. Prospective cohort study.
