Effects of power training on neuromuscular performance and mechanical efficiency

2007

Effects of power training with stretch-shortening cycle (SSC) exercises on mechanical efficiency (ME) were investigated with 9 young women who trained 3 times a week for 4 months. The training included various types of jumping exercises. Before and after the training as well as after the detraining (2 months) the subjects performed 6 different submaximal exercises with a special sledge apparatus. Each exercise involved 60 muscle actions lasting for a total of 3 min per testing condition. The work intensities were determined individually according to the recordings of distance obtained during the single maximal concentric exercises. The training caused the greatest changes of ME in condition…

Ankle-Brachial Index as a Predictor of Cardiovascular Risk in Atrial Fibrillation

2012

Objectives: Atrial Fibrillation (AF), the most frequent sustained arrhythmia, is associated with a high rate of morbidity and mortality. The clinical course of AF is often complicated by cardiovascular and cerebrovascular adverse events that usually have a dual origin: cardio embolic and atherothrombotic. The aim of our study is to demonstrate the existence of a relationship between Systemic Atherosclerosis and AF. More specifically, we have analysed the prevalence of lower limb Peripheral Artery Disease (PAD) in a population of fibrillating patients, and we have assessed whether the coexistence of AF and PAD might result in increased cardiovascular risks. Methods: The study has been conduc…

Association between frontal plane knee control and lower extremity injuries : a prospective study on young team sport athletes

2017

Background/aimPoor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased injury risk.MethodsA total of 306 basketball and floorball players participated in the baseline SLS test and a 12-month injury registration follow-up. Acute lower extremity time-loss injuries were registered. Frontal plane knee projection angles (FPKPA) during the SLS were calculated using a two-dimen…

Identification of normal and pathological posterior inter-malleolar ligament with dedicated high-field vs low-field MRI. A pilot study

2015

AIM the aim of the study was to determine an objective measure of detection of posterior inter-malleolar ligament (PIML) through a magnetic resonance (MRI) of the ankle with two dedicated scanners: high-field (1-Tesla: HMF) and low-field (0.2-Tesla: LMF). METHODS two-hundred subjects were randomly recruited for the study and then divided in two groups (HMF and LMF). We retrospectively evaluated the MRI of the ankle in the two groups of patients. PIML evaluation was performed globally and separately using different scan planes. RESULTS in HMF and LMF, the PIML was identified respectively in 55 and 11% of cases. PIML was classified as "indeterminate" in 28 and 57% of patients, and "absent" in…

Individual muscle contributions to the in vivo achilles tendon force

1998

OBJECTIVE: To ascertain the possibility of non-uniform stress within the achilles tendon due to individual force contributions of the triceps surae. DESIGN: Calculation of non-uniform stress through discrepancies in moments about the ankle joint. BACKGROUND: Non-uniform stress over the cross-sectional area have been implied in the etiology of achilles tendon injury and may influence functional aspects. However, this has not been empirically demonstrated. METHODS: In vivo achilles tendon forces were measured with an optic fibre technique during isometric plantarflexions at systematically varied knee angles and contraction intensities. A comparison to the plantar force measured underneath the…

EFFECTS OF STRIKING STRATEGY ON LOWER EXTREMITY LOADING DURING RUNNING

2013

Backround It is expected that every second runner has a running-related overuse injury each year. The knee joint and Achilles tendon are the most commonly injured sites covering both about one fifth of all running related injuries. 1 Runners can be categorized into rearfoot strikers, mid-foot strikers or forefoot strikers based on the landing strategy at the instant of initial ground contact. Forefoot or mid-foot striking has been shown to reduce impact peak and loading rate of the ground reaction force during early stance phase. 2 Furthermore, the finding of the recent study suggest that forefoot striking may potentially decrease the risk of running-related injuries. 3 However, the effect …

Walking and Running Require Greater Effort from the Ankle than the Knee Extensor Muscles.

2016

The knee and ankle extensors as human primary antigravity muscle groups are of utmost importance in a wide range of locomotor activities. Yet, we know surprisingly little about how these muscle groups work, and specifically, how close to their maximal capacities they function across different modes and intensity of locomotion. Therefore, to advance our understanding of locomotor constraints, we determined and compared relative operating efforts of the knee and ankle extensors during walking, running, and sprinting.Using an inverse dynamics biomechanical analysis, the muscle forces of the knee and ankle extensors during walking (1.6 m·s), running (4.1 m·s), and sprinting (9.3 m·s) were quant…

The Retrograde Tibial Nail: presentation and biomechanical evaluation of a new concept in the treatment of distal tibia fractures.

2013

Displaced distal tibia fractures require stable fixation while minimizing secondary damage to the soft tissues by the surgical approach and implants. Antegrade intramedullary nailing has become an alternative to plate osteosynthesis for the treatment of distal metaphyseal fractures over the past two decades. While retrograde intramedullary nailing is a standard procedure in other long bone fractures, only few attempts have been made on retrograde nailing of tibial fractures. The main reasons are difficulties of finding an ideal entry portal and the lack of an ideal implant for retrograde insertion. The Retrograde Tibial Nail (RTN) is a prototype intramedullary implant developed by our group…
