Factors associated with body size perception among adolescent goal-oriented sports participants and non-participants: a cross-sectional Finnish study.

Background: Regardless of competitive athletes' body image pressures, only few studies have focused on adolescent sport participants' body image and the findings are inconclusive. Furthermore, the role of competitive goals in sports on adolescents' body size perception has not been studied. We examined the factors associated with adolescents' competitive goals in sports and body size perception, and the associations between adolescents' competitive goals in sports and body size perception.

What is the relationship between physical activity and chronic pain in older adults? A systematic review and meta-analysis protocol.

Introduction: Chronic pain is highly prevalent in older adults and can cause functional limitations, negatively affecting health and quality of life. Physical activity is a non-pharmacological approach used to prevent chronic pain as it promotes the release of endogenous opioids that block pain sensitivity. Therefore, we developed a systematic review protocol to analyse the relationship between physical activity and the occurrence and intensity of chronic pain in older adults.

The mid-term effect of Osgood-Schlatter disease on knee function in young players from elite soccer academies.

Background: The aim of the study was to evaluate the effect of Osgood-Schlatter disease (OSD) on knee joint function in elite young soccer players. Our hypothesis was that knee joint function in elite young soccer players was impaired following OSD compared with soccer players with no history of OSD.

Method: In young male soccer players (n = 36) from elite academies (mean ±SD, age: age: 15,3 ± 1,7 years; height: 1,7 ± 0,06 m; weight: 63,5 ± 8 kg; BMI: 20,7 ± 2).

Patients that maintain their pre-injury level of physical activity 3-5 years after ACL reconstruction are, 18 months after surgery, characterised by higher levels of readiness to return to sport.

Purpose: To characterise patients who had returned to their pre-injury physical activity (PA) or higher at 18 months and maintained that level of PA 3-5 years after the primary ACL reconstruction and to describe the level, frequency, and type of PA participation during the first 5 years after ACL reconstruction  METHOD: Data, from follow-ups at 18 months and 3-5 years after an ACL reconstruction, were extracted from a rehabilitation-specific register. Patients, 15-65 years of age, were included. The data comprised patient-reported outcomes and the results from two questions with respect to the level, frequency, and type of PA.

Walk Smarter, Not Harder: Effects of Cadence Manipulation on Gait Biomechanics in Patients with Patellofemoral Osteoarthritis.

Purpose: This study aimed to investigate the effect of walking cadence on knee flexion angular impulse and peak external flexion moment in patients with patellofemoral osteoarthritis (OA).

Methods: Forty-eight patients with patellofemoral OA underwent repeated quantitative gait analyses on an instrumented treadmill using a randomized crossover design. Walking trials were conducted at a fixed gait speed, under three cadence conditions: (i) preferred cadence, (ii) +10% increased cadence, and (iii) -10% decreased cadence, completed in random order.

High quality rehabilitation to optimize return to sport following lateral meniscus surgery in football players.

There is a paucity of studies in the literature pertaining about how to guide rehabilitation and return to sport (RTS) progression for football players that have sustained a lateral meniscus injury and subsequent surgery. These patients are clinically challenging. If they return to sport too soon, before the rehabilitation process is completed and RTS criteria have been met, functional outcomes could be non-optimal and/or associated with higher reinjury risk.

Epidemiology of the Injuries Sustained by Elite Spanish under-18 and under-20 Rugby Players.

This study examines the injuries suffered by players (n=166) of the Spanish national men's under-18 and under-20 rugby teams between 2015 and 2017, and identifies the actions involved in their occurrence. All injuries (total n=78) sustained during matches and training were recorded as recommended by World Rugby, and injury incidence rates per 1000 player-hours (ph) calculated for both types of activity. Injuries occurred more commonly during matches than during training (incidence 105.

Treatment of Distal Patellar Tendon Chronic Rupture: The X-Wave Technique.

Injuries to the patellar tendon (PT) are associated with knee function deterioration and loss of the capacity to perform daily and sports activities. Patellar tendon injury is often misdiagnosed at emergency rooms, leading to chronic proximal retraction and a challenging clinical scenario. Proximal PT injuries are more common, while distal ones, which can involve tibial bone avulsion fractures or direct tendon avulsion, are rarer.
