Results: Male amateur rugby league players experienced more head impacts than female amateur rugby league players (470 ☒08 vs. All impact data were collected and downloaded for further analysis.

Methods: 21 female and 35 male amateur rugby league players wore wireless impact measuring devices (X2Biosystems xPatch) behind their right ear over the mastoid process during match participation across a single season. Purpose: To quantify the magnitude, frequency, duration and distribution of impacts to the head and body in rugby league match activities for females versus males.ĭesign: Prospective descriptive epidemiological study. Biomechanical factors may result in greater post-impact head velocities and accelerations for a given force for females when compared with males. Our findings suggest that OAC can become the cell source for ACI.īackground: Epidemiological studies report that females experience greater rates of concussion when compared with males. The changes in cell surface markers and chondrogenic related genes showed similarity for both the groups. There were no statistical differences in the Bern Scores between OAC and non-OAC.Ĭonclusion: The chondrocytes from OA patients and young adult patients had chondrogenic re-differentiation potential. The expression of COL2 decreased from passage 1 to passage 3 in both the groups. The expression of CD105 was upregulated from passage 1 to passage 3 in OAC, and it increased at the same level as in non-OAC during passage 2 and 3. Results: OAC and non-OAC had comparable positive ratios for CD44, CD73, CD90, and CD105. Real-time PCR were performed to measure the chondrogenic related genes transcriptional levels. Chondrocytes of passage 4 were cultured as pellets for re-differentiation and evaluated histologically. The chondrocytes from passages 1 to 3 were analyzed for the expression of cell surface markers (CD73, CD90, CD105, and CD44) by flow cytometric analysis. Methods: Chondrocytes from five old patients with knee OA (OAC) and five young patients with recurrent shoulder dislocation (non-OAC) were used. The purpose of this study was to compare the chondrogenic re-differentiation potential of chondrocytes, from osteoarthritis (OA) patients and young adult patients, after monolayer culture. This “de-differentiation” is expected to restore the chondrogenic properties such as “re-differentiation” in autologous chondrocyte implantation (ACI). Purpose: Monolayer passage of chondrocytes results in dramatic phenotypic changes. There were no changes in baseline blood pressure levels. Furthermore, the short CR program decreased waist and hip circumferences, being an important option for these subjects. After 16 CR sessions, functional and musculoskeletal capacity was improved, evaluated by 6-MWT. In conclusion, the results suggest that a short CR is an effective for the treatment of hypertensive subjects. About the mean distance walked in the 6-MWT there was an increase after the CR program (335.9☑23.5 m to 554.56☘7.9 m, p=0.000). The results shown that after CR occurred a reduction of waist circumference (99.86☘.7 to 95.2☘.6 cm, p=0.0002) and hip circumference (110.18☑4.75 to 105.00☑2.7 cm p=0.01) values. CR was performed twice a week for 60 minutes. It was evaluated the weight, height, body mass index (BMI), waist and hip circumference, waist hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP) and six-minute walk test (6-MWT) before and after CR.

The clinical pilot study involved a sample composed of 11 hypertensive subjects.

The aim of the present study was to verify the effects of a short cardiovascular rehabilitation program (CR) in hypertensive subjects. Systemic arterial hypertension (SAH) is considered an important risk factor for the development of cardiovascular diseases.
