Eight weeks of <Emphasis Type="Italic">Capoeira</Emphasis> progressive training program increases flexibility of beginners

Background

No study has investigated the alterations in the flexibility of beginners using an experimental protocol with basic techniques of Capoeira.

Purpose

To analyze the effects of 8 weeks of Capoeira progressive training program on the flexibility of beginners.

Methods

Twenty-one individuals divided in two groups (Capoeira: n = 13; 26.1 ± 7.2 years; 22.7 ± 2.7 kg m^2(?1) and control: n = 08; 27.1 ± 0.5 years; 24.3 ± 3.3 kg m^2(?1)) participated in the study. The Capoeira group performed 8 weeks of Capoeira progressive training program (two sessions per week lasting 60 min each). The experimental protocol used was exclusively based on the basic techniques of a programmed Capoeira training system. Before and after the intervention, measurements were performed aiming to analyze (1) trunk flexion flexibility through a sit-and-reach test using a Wells’ Bench (WB_tf), (2) passive tension (PT_hf), and (3) maximum amplitude of hip flexion (MA_hf) through goniometry.

Results

A two-way ANOVA revealed a main effect of group by time interaction to PT_hf (F = 11.797; P = 0.003; η _p ²  = 0.383) and MA_hf (F = 9.650; P = 0.006; η _p ²  = 0.337). No significant main effect of group by time interaction occurred to WB_tf (F = 3.320; P = 0.084; η _p ²  = 0.149). The relative changes (? %) before and after the intervention in both groups showed that the Capoeira group significantly differed to the control group in the PT_hf (Capoeira: 46.2 ± 29.9 % vs. control: 5.7 ± 27.6 %; P = 0.003) and MA_hf (Capoeira: 22.4 ± 24.5 % vs. control: ?6.1 ± 13.1 %; P = 0.006).

Conclusion

Eight weeks of Capoeira progressive training program resulted in a significant improvement in angular flexibility for beginners.

     

Amphotericin B-Loaded Poly(lactic-co-glycolic acid) Nanofibers: An Alternative Therapy Scheme for Local Treatment of Vulvovaginal Candidiasis

Vulvovaginal candidiasis is an inflammation localized in the vulvovaginal area. It is mostly caused by Candida albicans. Its treatment is based on the systemic and local administration of antifungal drugs. However, this conventional therapy can fail owing to the resistance of the Candida species and noncompliance of patients. Amphotericin B-loaded poly(lactic-co-glycolic acid) nanofibers are single-use, antifungal, controlled drug delivery systems, and represent an alternative therapeutic scheme for the local treatment of vulvovaginal candidiasis. Nanofibers were characterized by analytical techniques and with an in vitro drug delivery study. In vitro and in vivo fungicidal activity of amphotericin B released from nanofibers was evaluated using the agar diffusion method and an experimental murine model of vulvovaginal candidiasis, respectively. Analytical techniques showed that amphotericin B was physically mixed in the polymeric nanofibers. Nanofibers controlled the delivery of therapeutic doses of amphotericin B for 8 consecutive days, providing effective in vitro antifungal activity and eliminated the in vivo vaginal fungal burden after 3 days of treatment and with only one local application. Amphotericin B-loaded poly(lactic-co-glycolic acid) nanofibers could be potentially applied as an alternative strategy for the local treatment of vulvovaginal candidiasis without inducing fungal resistance, yet ensuring patient compliance.
