Thirty-six male professional soccer players (age: 18.9 ± 1.4 years) were divided into 3 groups, the 11+, HarmoKnee and control group (n = 12 per group). The experimental groups performed the programs 3 times per week for 2 months (24 sessions), whereas the control group only performed their regular soccer training. The performance tests carried out were: 10m speed tests with and without a ball, 20m single sprint, vertical jump, Wall-Volley and Illinois agility tests. The 11+ group demonstrated significant increases from pre-to-post time points in the vertical jump (3.7%), Wall-Volley (5.4%) and Illinois agility tests (1.7%), while the HarmoKnee group showed a significant increase in Wall-Volley test, with a 5.2% increase. The repeated measures analysis revealed differences between the groups (large effect size) in the 11+ and HarmoKnee groups, compared to the control group, in 10m speed tests with and without a ball, 20m single sprint and Illinois agility tests (p < 0.05). Thus 8-weeks performing the 11+ warm-up program can enhance jump height, agility and soccer skill while the HarmoKnee program generally only improves soccer skill in young professional male soccer players.

Athletes who suffered from these injuries experienced a decrease in performance and physical disability. Although a variety of treatments have been implemented to the muscle injuries, the administration of autologous blood injection is replacing the conventional rehabilitation to expedite the process of muscle recovery. Platelet-rich plasma (PRP) is relatively new in muscle injury treatment and there is lack of evidence of the satisfaction of PRP treatment in muscle injuries. Purposes: The study aimed to investigate the patient satisfaction in the administration of PRP treatment and rehabilitation program for acute hamstring strain injury. Methods: Participants (competitive, semi-competitive and recreational athletes) with acute hamstring strain injury (Grade II) were recruited. Participants were randomly divided into either the PRP treatment or rehabilitation program. Participants were required to attend weekly follow up assessment for recovery evaluation. All the participants were required to complete a patient satisfaction questionnaire (PSQ-18) at the end of study. The questionnaire is divided into seven sub-scales: general satisfaction, technical quality, interpersonal manner, communication, financial aspect, time spent with doctor, accessibility and convenience. Results: Participants were 22.35 ± 3.41 years. Duration from injury to first presentation in clinic ranged from two to ten days. Mean duration of recovery was 5.64 weeks. No statistically significant difference in the patient satisfaction sub-scales score between the two groups (p>0.05). Conclusion: The present study demonstrates that PRP treatment is as satisfactory as conventional rehabilitation program in managing acute hamstring strain injury. Both modalities are correspondingly safe and have high degree of satisfaction. Given the acceptable outcomes, patients are likely to accept PRP as an effective treatment.

Fifteen collegiate soccer players (height: 173.07 ± 7.81 m; mass: 67.60 ± 8.73 kg; age: 24.73 ± 4.59 years; experience: 7.27 ± 2.09) were tested for agility performance using the Illinois agility test and also for power using vertical jump test after warm up completion and at 15 minutes later. Different warm-ups protocols included static stretching, dynamic stretching and no stretching. The current findings showed significant differences on height jump and agility time as compare to static and no stretching methods. There were no significant differences between the first and second posttests after dynamic, static and no stretching methods. We concluded that collegian soccer players probably perform better agility and power after dynamic stretching as compare to static stretching and their muscular performances could be able to sustain in higher level as compare to static stretching.

Swimming is classified as an overhead sport, but a lack of attention regarding EP in swimming has created a gap in the knowledge around elite freestyle swimming in Tianjin, China. The purpose of this study was to identify the distribution and prevalence of EP among elite freestyle swimmers in Tianjin, China. The methodology involved a total of 311 qualified participants who volunteered to undertake all measurements. The main findings showed that 183 of the elite freestyle swimmers in this study had EP (accounting for 58.84% of the total 311 participants), with 147 in slight pain and 36 in critical pain. The characteristics of a heavier body weight, taller height, longer left/right forearm length, and longer weekly average training hours serve as contributing factors to the occurrence of EP issues. Gender, age, weekly average training hours, and left/right forearm length are the primary factors correlating with and influencin...

In view of that, lipid mobilization and utilizations would be the main mechanisms involved. The purpose of the investigation was to determine whether acute consumption of Eurycoma longifolia Jack extract would influence lipolysis among athletes. Ten male athletes were randomly assigned either to Eurycoma longifolia Jack group (EL, n = 5) or placebo group (PG, n = 5). Athletes from both groups ingested 1.7 mg/kg of body weight of either EL or PG for three days prior to the treadmill exercise test (65% of VO2max) for an hour. Plasma free fatty acid (FFA), glycerol and triglycerides (TG) levels were measured at pre-exercise and post-exercise on days 0 and 3. Plasma FFA in EL group was significantly lower than that in PG after 3 days (p < 0.05), and plasma glycerol level was significantly increased in EL compared to PG (p < 0.05). The results of this study suggest that EL supplementation could promote fat lipolysis, resulting towards better energy yield. Therefore, EL can be considered as an ergogenic aid to improve performances and to boost energy production.

Under-21-year-old players (n=36) were divided equally into: the 11+, HarmoKnee and control groups. The programmes were performed for 24 sessions (20-25 min each). The hamstrings and quadriceps strength were measured bilaterally at 60°•s-1 , 180°•s-1 and 300°•s-1. The concentric quadriceps peak torque (PT) of the 11+ increased by 27.7% at 300°•s-1 in the dominant leg (p<0.05). The concentric quadriceps PT of HarmoKnee increased by 36.6%, 36.2% and 28% in the dominant leg, and by 31.3%, 31.7% and 20.05% at 60°•s-1 , 180°•s-1 and 300°•s-1 in the non-dominant leg respectively. In the 11+ group the concentric hamstring PT increased by 22%, 21.4% and 22.1% at 60°•s-1 , 180°•s-1 and 300°•s-1 , respectively in the dominant leg, and by 22.3%, and 15.7% at 60°•s-1 and 180°•s-1 , in the non-dominant leg. In the HarmoKnee group the hamstrings in the dominant leg showed an increase in PT by 32.5%, 31.3% and 14.3% at 60°•s-1 , 180°•s-1 and 300°•s-1 , and in the non-dominant leg hamstrings PT increased by 21.1% and 19.3% at 60°•s-1 and 180°•s-1 respectively. The concentric hamstrings strength was significantly different between the 11+ and control groups in the dominant (p=0.01) and non-dominant legs (p=0.02). The HarmoKnee programme enhanced the concentric strength of quadriceps. The 11+ and HarmoKnee programmes are useful warm-up protocols for improving concentric hamstring strength in young professional male soccer players. The 11+ programme is more advantageous for its greater concentric hamstring strength improvement compared to the HarmoKnee programme.

However, previous trials mostly examined the effects of HBE and EDU separately. Thus, this study aimed to evaluate the effects of a structured combined HBE and EDU program in addition to usual KOA rehabilitation on pain score, functional mobility, and disability level. Study Design: A parallel-group, single-blinded randomized controlled trial. Methods: Eighty adults with KOA were randomly allocated to experimental (n=40) and control (n=40) groups. All participants underwent their usual physiotherapy care weekly for eight weeks. The experimental group received a structured HBE+EDU program to their usual care, while the control group performed home stretching exercises to equate treatment time. The Knee Injury and Osteoarthritis Outcome Score (KOOS) for the disability level, visual analogue scale (VAS) for pain, and timed up-and-go test (TUG) for mobility were measured pre-post intervention. Results: After eight weeks, the experimental group demonstrated significant improvements in the KOOS (all subscales), pain VAS, and TUG scores compared to baseline (P<0.001); meanwhile, only KOOS (activities of daily living and sports subscales) was significant in the control group. Relative to the control, the experimental group presented higher improvements (P<0.001) by 22.2%, 44.1%, and 15.7% for KOOS, pain VAS, and TUG, respectively. Conclusion: Integrating the HBE+EDU program into usual KOA rehabilitation could reduce pain and disability, while it improved functional mobility. The finding of this study suggests a combination of a structured HBE and EDU program to be considered as part of mainstream KOA management.

Design: The acute toxicity test was carried out to choose the safe doses and identify the toxicity effects of the fenugreek seed extract. To investigate the hypoglycemic effect of the extract and its effect in combination with swimming training, 80 Wistar Kyoto male streptozotocin-induced diabetic rats were divided randomly into eight groups: diabetic control (C); fenugreek seed extract 0.8 g/kg (F1); fenugreek extract 1.6 g/kg (F2); swimming training (S); swimming training plus fenugreek extract 0.8 g/kg (SF1); swimming training plus fenugreek extract 1.6 g/kg (SF2); glibenclamide (G) and swimming training plus glibenclamide (SG). The rats were orally administrated with the treatments once a day with the respective treatment, and the training groups were subjected to swimming training every day for 60 min. Fasting blood samples were collected to measure fasting blood glucose, lipid profile, adiponectin, leptin, and insulin concentrations. Results: The results obtained from acute toxicity study showed no toxicity effect of fenugreek seed extract on the tested dose. Biochemical analysis showed significant improvements in all of the groups compared to the control group (p B0.05). Plasma insulin concentration and insulin resistance (HOMA-IR) was significantly reduced in treated groups compared with the diabetic control group. Plasma leptin were significantly decreased in treated groups compared with the control group; while adiponectin had markedly increased (p B0.05). Conclusion: The findings suggest that fenugreek seed consuming, alongside swimming exercise, has a strong therapeutic effect on the improvement of diabetic parameters.

Aim: To compare the effects of LLLT and HILT as adjuncts to rehabilitation exercise (LL+EX and HL+EX) on clinical outcomes in KOA. Methods: Thirty-four adults with mild to moderate KOA were randomly allocated to either LL+EX (n = 17) or HL+EX (n = 17) groups. All participants underwent their designated laser treatment combined with rehabilitation exercises weekly for twelve consecutive weeks. The Knee Injury and Osteoarthritis Outcome Score (KOOS), Numerical Pain Rating Scale (NPRS), active knee flexion, and Timed Up-and-Go test (TUG) were assessed at baseline and immediately post-intervention. Results: Post-intervention, both groups significantly improved their KOOS, NPRS, active knee flexion, and TUG scores compared to baseline (p < 0.01). The mean differenc...

A propriety standardized extract of Eurycoma longifolia Jack (Physta®) was tested for anti-viral activity after viral adsorption in Vero cell line. Viral yield was measured by qRT-PCR in four serotypes of dengue virus. The antiviral activity was further investigated in an in vivo AG129 mouse model for dengue inhibitory candidates. 100 mg/kg EL extract was fed twice daily and challenged with a lethal dose of (~1x105 PFU per mouse) of DENV-2 over a period of six days. Antiviral activity with IC50 of 33.84, 33.55, 58.35 and 119 µg/ml for DENV-1, DENV-2, DENV-3 and DENV-4 serotypes respectively was observed. The selectivity index (SI) values determined as the ratio of cytotoxic concentration (CC50) to inhibitory concentration (IC50) was the lowest for DENV-2 at 28.9.

Objective: This study investigated the safety and efficacy of Eurycoma longifolia in combination with multivitamins (EL+MV) versus placebo on improving quality of life (QoL), mood and stress in moderately stressed healthy participants. Methods: This randomised, double-blind, placebo-controlled 24-week study enrolled 93 participants aged 25-65 years, with a body mass index of 18-30 kg/m 2 , scoring ≤18 in tension and ≤14 in fatigue subscale of Profiles of Mood Scores (POMS) questionnaire and supplemented with EL+MV or placebo. The primary endpoints were QoL measured by 12-Item Short Form Health Survey (SF-12) questionnaire and mood measured by POMS. The secondary endpoint was stress measured by Multi-Modal Stress Questionnaire (MMSQ). The safety of the intervention product was measured by complete metabolic panel, lipid and renal analysis including several immune parameters. Results: While there were no significant between-group differences, within-group improvements were observed in the SF-12 QoL, POMS and MMSQ domains. In the SF-12 domain, improvements were seen in role limitation due to emotional health (P = 0.05), mental component domain (P < 0.001), emotional well-being (P < 0.001), social functioning (P = 0.002) as well as vitality (P = 0.001) at week 12. An increasing trend in POMS-vigour domain was also observed in the EL+MV group at week 12. A 15% decrease in physical stress domain (P < 0.05) compared with 0.7% in the placebo group was also observed in MMSQ. When the subjects were subgrouped according to age, 25-45 and 46-65 years of age, for primary outcomes, between-group significance was observed in the 25-45 year group in the social functioning domain of SF-12 (P = 0.021) and POMS-vigour (P = 0.036) in the 46-65 year group. No significant changes were observed in vital signs and complete metabolic panel. Regarding immune parameters, the lymphocytes increased significantly in the active group (P≤0.05). In total, 13 adverse events were reported: six on placebo and seven on EL+MV. Conclusion: EL+MV may support the QoL, mood, stress and immune parameters in healthy participants. Trial registration: This study has been registered at clinicaltrials.gov (NCT02865863).

This review aimed to elucidate findings on the effects of honey on exercise performance as well as combined effects of honey and exercise on health-related outcomes. Methods.-Literature was searched systematically based on PRISMA guidelines, using PubMed, Science Direct, SPORTDiscus and Web of Science databases. Thirteen human and animal studies were included in the final analysis. Surprisingly, there were only three randomised-controlled studies that investigated the effect of honey on exercise performance per se, meanwhile, ten reported the combined effects of honey and exercise on bone health, hormones, immune system, and inflammation. Acute honey ingestion improved endurance performance in two studies, while, five studies reported improvements in bone health after consuming honey combined with jumping exercises or aerobic dance. One study reported that stress and reproductive hormones were positively regulated. Five studies reported increase in white blood cells and neutrophils after ingesting honey combined with resistance or aerobic exercises which boosted the immune system. Conclusion.-Honey alone could potentially improve aerobic exercise performance; however studies are limited. Meanwhile, honey in combination with exercise promotes bone health and improves immune systems. It is believed that CHO and other constituents of honey play an important role during exercise in exerting the said benefits.

This calls for quality tests that are replicable. However, current tortilla quality testing relies heavily on subjective tests with unknown reliability. This study aimed to determine the relationship between subjective tortilla quality testing and available objective methods, and assess whether the latter can potentially replace the former. Correlation and regression analyses were done using data on subjective opacity and rollability, and objective L* value and texture parameters based on 114 wheat samples. Opacity scores and L* values were significantly correlated, but this relationship was affected by evaluator experience; in a controlled setting, experienced evaluators scores were more reliable (SEM = ±0.25 – 3.8, r = 0.96) than less experienced evaluators (SEM = ±0.25 – 7.3, r = 0.92). Tortilla rollability, which approximates shelf stability, correlated most strongly with the rupture distance from two-dime...
