*** There is a growing body of research supporting the idea that a plethora of health benefits can result from resistance training using a low volume,high-effort approach(e.g.,increased metabolic rate and bone mineral density,a reduction in blood pressure,and improved muscle quality and insulin sensitivity,among ***,muscular strength and muscle massprimary goals and benefits of participation in resistance trainingare independently strong predictors of longevity and quality of life. Thus,many have sought to identify how the manipulation of resistance training variables might lead to“optimal”adaptations in such outcomes,as evidenced by repeated attempts over recent decades to review the literature and provide consensus statements on this topic.5-10 One variable that is often hotly debated within resistance training is training to failure.

Poly lactic acid is a biodegradable, biocompatible, and non-toxic polymer, widely used in many pharmaceuticalpreparations such as controlled release formulations, parenteral preparations, surgicaltreatment applications, and tissue engineering. In this study, we prepared lipid-polymer hybrid nanoparticlesfor topical and site targeting delivery of Norfloxacin by emulsification solvent evaporationmethod (ESE). The design of experiment (DOE) was done by using software to optimize the result, andthen a surface plot was generated to compare with the practical results. The surface morphology, particlesize, zeta potential and composition of the lipid-polymer hybrid nanoparticles were characterized bySEM, TEM, AFM, and FTIR. The thermal behavior of the lipid-polymer hybrid nanoparticles was characterizedby DSC and TGA. The prepared lipid-polymer hybrid nanoparticles of Norfloxacin exhibited anaverage particle size from 178.6 ± 3.7 nm to 220.8 ± 2.3 nm, and showed very narrow distribution withpolydispersity index ranging from 0.206 ± 0.36 to 0.383 ± 0.66. The surface charge on the lipid-polymerhybrid nanoparticles were confirmed by zeta potential, showed the value from t23.4 ± 1.5 mVto t41.5 ± 3.4 mV. An Antimicrobial study was done against Staphylococcus aureus and Pseudomonasaeruginosa, and the lipid-polymer hybrid nanoparticles showed potential activity against these ***-polymer hybrid nanoparticles of Norfloxacin showed the %cumulative drug release of 89.72% in24 h. A stability study of the optimized formulation showed the suitable condition for the storage oflipid-polymer hybrid nanoparticles was at 4 ± 2 C/60 ± 5% RH. These results illustrated high potential oflipid-polymer hybrid nanoparticles Norfloxacin for usage as a topical antibiotic drug carriers.

Purpose Sled towing has been shown to be an effective method to enhance the physical qualities in youth *** aim of this study was to evaluate the impact of a 6-week sled towing intervention on muscular strength,speed and power in elite youth soccer players of differing maturity *** Seventy-three male elite youth soccer players aged 12-18 years(Pre-Peak Height Velocity[PHV]n = 25;Circa-PHV n = 24;Post-PHV n = 24)from one professional soccer academy participated in this *** assessments(10 m and 30 m),countermovement jump and isometric mid-thigh pull were undertaken before(T1)and after(T2)a 6-week *** training intervention consisted of 6 weeks(2xper week,10 sprints over 20 m distance)of resisted sled towing(linear progression 10%-30%of body mass)during the competitive *** regression models analysed differences between T1 and T2 within each maturity *** There were minimal changes in strength,speed and power(P=0.35-0.80)for each maturity group across the 6-week *** there were changes with greater certainty,they are unlikely to represent real effect due to higher regres-sion to the mean(RTM).Conclusion It appears that a 6-week sled towing training programme with loadings of 10%-30%body mass only maintains physical qualities in elite youth soccer players pre-,circa-,and *** research is required to determine the effectiveness of this training method in long-term athletic development programmes.
