Case-control study.
Social media, private ...practice and National Health Service.
An international sample of jumping athletes diagnosed with either PT (n = 132; 30.7 ± 8.9 years; 80 males; VISA-P = 61.6 ± 16.0) or another musculoskeletal knee condition (n = 89; 31.8 ± 9.9 years; 47 males; VISA-P = 62.9 ± 21.2) by a clinician in the last 6 months.
We considered clinical diagnosis (case = having PT vs control = having other knee problems) as the dependent variable. Severity and sporting impact were defined by VISA-P and availability, respectively.
A model comprising seven factors distinguished PT from other knee problems; training duration (OR = 1.10), sport type (OR = 2.31), injured side (OR = 2.28), pain onset (OR = 1.97), morning pain (OR = 1.89), condition acceptability (OR = 0.39) and swelling (OR = 0.37). Sports-specific function (OR = 1.02) and player level (OR = 4.11) explained sporting availability. 44% of PT severity variance was explained by quality of life (β = 0.32), sports-specific function (β = 0.38) and age (β = −0.17).
Sports-specific, biomedical and psychological factors partially distinguish PT from other knee problems. Availability is mainly explained by sports-specific factors, while psychosocial factors impact on severity. Adding sports-specific and bio-psycho-social factors into assessments could help better identification and management of jumping athletes with PT.
•Athletes with patellar tendinopathy play twice as much as those with other knee problems.•Yet they are less satisfied with their recovery.•Compromised participation is mainly explained by sports specific function and playing level.•Quality of life impacts on severity as a psychosocial factor.•Self-reported findings add value to assessment.
Workout programmes have proven physiological benefits, and it is widely accepted that they can yield more positive health outcomes when parameters such as balance and mobility are at play. This study ...intends to examine the effects of a 12-week mat pilates workout program on mobility and dynamic balance parameters in the former athlete group (FAG) and the sedentary group (SG). The study was designed in an experimental design with pre-test and post-test in two groups. The study group consisted of 30 female participants, SG (n=15) and FAG (n = 15). Dynamic balance values were measured using the Star Excursion Balance Test, and lower extremity mobility was measured using the Sit and Reach Test. Both groups conducted mat pilates exercises twice a week for 12 weeks. At the end of the 12-week mat pilates workout programme, a significant difference of increase was obtained in the mobility values of the FAG (p<0,002) and the SG (p<0,001). The Y Balance Test identified a significant difference of increase with pre-test and post-test in anterior (p = 0.04), postero-lateral (p = 0.03), posteromedial (p = 0.04) directions balance in the FAG. In the difference between groups, SG showed a significant increase in posterolateral (p = 0.001) and posteromedial (p = 0.002) directions balance than FAG at post-test. At the end of the 12-week mat pilates workout programme, it was revealed out that the FAG scored better in post-test in dynamic balance than the SG although it scored lower in the dynamic balance pre-test than the SG.
To investigate the effect of a 6-week stroboscopic balance training program on cortical activities in athletes with chronic ankle instability.
Randomized controlled trial. Setting: Single-center.
...Thirty-nine participants were assigned to the strobe group (SG, n = 13), non-strobe group (NSG, n = 13), and control group (CG, n = 13).
Cortical activity and balance velocity were evaluated while the athletes were on the HUBER balance device. Electroencephalographic measurements of cortical activity were made at the transition from bipedal stance to single-leg stance.
The SG showed significant increases in Cz theta and alpha values and COP-v (center of pressure velocity) between pretest and posttest (p < 0.001, p = 0.003, p < 0.001). Posttest Cz theta was significantly higher in the SG compared to the CG (p = 0.009) and posttest Cz alpha was significantly higher in the SG compared to the NSG (p = 0.039) and CG (p = 0.001). Posttest COP-v was significantly higher in the SG than in the CG (p = 0.031) and NSG (p = 0.03).
Stroboscopic training may be clinically beneficial to improve balance parameters in athletes with CAI, and may have utility in sport-specific activity phases of rehabilitation to reduce visual input and increase motor control.
•Strobe training increases theta and alpha waves on cortical activities.•Strobe training increases center of pressure velocity.•Stroboscopic training can be used to enhance traditional balance training.
Aim: This study aims to explore the relationship between short-distance speed performance and agility in male and female tennis players who play three times weekly, highlighting the differences in ...speed and agility based on gender over distances of 5-10 meters. Method: The sample consisted of 20 university students from the Faculty of Sports Sciences, with an average age of 21 ± 1.5 years, equally divided by gender, all regularly participating in tennis training. To assess acceleration, 5m and 10m sprint tests were conducted, alongside the T-Test for agility evaluation. The Pearson Correlation test examined the link between agility and speed, while an independent samples T-test compared gender-specific test scores. Findings: Findings reveal a significant correlation between agility and both 5m (r=.741; p<0.01) and 10m (r=.806; p<0.01) sprint times, indicating a strong relationship between these aspects. Notably, significant differences in agility and sprint times were observed between genders, suggesting inherent performance variances. Conclusion: Consequently, enhancing speed attributes in tennis is believed to significantly boost agility performance. It is recommended that training programs focusing on speed development should be utilized, incorporating these gender differences into the training regime to optimize athlete performance. This study underscores the integral role of speed in improving agility within tennis, advocating for tailored training approaches.
Peppers are one of the most widely processed and consumed vegetables in the world. The present study was established to obtain phenolic profiles of two fresh and oven-cooked pepper cultivars, red hot ...Aleppo (
Capsicum annuum
L.) and red sweet pepper Capia (
Capsicum annuum
L.). Phenolic extracts of pepper samples have been, for the first time, qualitatively and quantitatively examined by liquid chromatography including tandem mass spectrometry (LC–MS/MS). Apart from the main objective, samples were also examined for their colour alteration regarding the oven cooking process. A total of 20 phenolic compounds were identified and quantified in the red pepper samples. The revealed results showed that the hot Aleppo pepper possessed a much higher phenolic content when compared to Capia peppers. In the Aleppo pepper samples, capsaicin, luteolin 6,8-di-
