This study aimed to contrast the impacts of an exercise intervention using either bounce drop jump (DJ; fast stretch-shortening cycle exercise) or countermovement jump (CMJ; slow stretch-shortening cycle exercise) on measures of physical fitness in young females. A total of 23 young females (age: 19.7 ± 1.0 years, height: 159.8 ± 4.2 cm, body mass: 54.3 ± 14.3 kg) were randomly assigned to either DJ (n = 12) or CMJ (n = 11) training, which spanned 6 weeks. Pre- and posttraining assessments were conducted for 10 m and 30 m linear sprints, change-of-direction speed, CMJ, DJ (jump height, contact time, and reactive strength index), standing long jump, triple-hop distance, and isometric strength. Apart from the variance in jump technique, both interventions were standardized in terms of total repetitions, intensity, and surface type. No significant Group × Time effect was observed in any dependent variables (all p > .05). A significant time effect was observed in 10 m (p < .001, effect size [ES] = 0.70) and 30 m (p < .001, ES = 0.79) linear sprint, CMJ height (p = .012, ES = 0.34), DJ contact time (p = .012, ES = 0.34), and triple-hop distance (p = .006, ES = 0.38). Both DJ and CMJ training interventions led to comparable improvements in linear sprints, CMJ height, DJ contact time, and triple-hop distance. These findings suggest that the duration of ground contact during intervention exercises (i.e., fast vs. slow stretch-shortening cycle) did not significantly influence initial (6 weeks) physical fitness adaptations in young females. However, extending these results to highly trained groups (e.g., athletes) warrants further investigation.

The aim of the study was to analyze the impact of two training models—the traditional methodology and an alternative or nonlinear mixed methodology—on coordination, speed, and changes of direction (COD) in U-12 football players. The subjects were divided into two groups: a traditional group of 11 female players and a second group of 14 female players, which followed a mixed methodology. Ten training sessions of 30 min were carried out focusing on motor coordination and COD. The variables analyzed were motor coordination with the SportComp test, COD with the Modified Agility test, and the Suttle Sprint and Dribbling test, with and without the ball, and speed over 30 m, with and without the ball. Overall, improvements were obtained in the mixed training program, leading to significant improvements (p < .05) in the variables of motor coordination, speed, and COD, with a large effect size. Therefore, coaches and physical trainers, taking into account that it causes greater benefits in the physical condition of female football players in training, than the traditional training program, can use the mixed training program.

Although the fluctuations of hormones over the menstrual cycle are well recognized, this study investigated the variability in these patterns for individual women. This study examined a set of daily blood hormone results from an underlying data set of previous research. Hormones included follicle-stimulating hormone (FSH), luteinizing hormone, progesterone, and estradiol taken over one menstrual cycle in 20 women of reproductive age (age 20–36 years), with ultrasound-confirmed ovulation. Although every woman’s profile of hormone changes was consistent with the expected physiological sequence of events, there was notable variability in the timing and peak levels. Variability in the length of the follicular phase was greater than in the length of the luteal phase, with the greater part of the variability in the cycle length being explained by variability in the follicular phase. Lower levels of FSH at the beginning of the cycle were associated with a longer follicular phase. Variability in the timing of events around ovulation was relatively consistent across all women. Variability in the length of the luteal phase was associated with the duration of elevated levels of progesterone. Differences were seen in the extent to which FSH increased at the end of the cycle. This study suggests the variability of the first part of the follicular phase may be due to initial FSH changes. Understanding the variability of menstrual cycle hormones is relevant for all women. Identifying subclinical ovulatory disturbances and variability is important to understand female health, across different populations including menstruating women and female athletes.

Background: Rates of low energy availability (LEA) in female footballers range from 12% to 66%, studies are limited, and no research has yet looked at the prevalence of LEA in a cohort of international players. Due to the negative consequences of LEA, more research is needed for a thorough investigation into prevalence rates and the associated risk factors of LEA within international environments. Methods: Twenty-two members of the New Zealand under 20 (U20) and National Women’s football teams (20.8 ± 3.5 years) participated in this study. Participants completed an online questionnaire composed of five independent validated surveys to assess LEA risk (Low Energy Availability in Females Questionnaire), eating disorder risk (Eating Disorder Examination Questionnaire), sleep quality (Athlete Sleep Score Questionnaire), nutrition knowledge, (Abridged Sport Nutrition Questionnaire), and mood (Profile of Mood States Questionnaire). Results: 59.1% (n = 13) of participants were identified as being at risk of problematic LEA. Players reporting menstrual disturbances (amenorrhea or oligomenorrhea) were 2.25 times more likely to be at risk of LEA than those who did not report a menstrual disturbance. Menstrual status (R = −.46, p = .030) and Profile of Mood States Questionnaire (r = −.46, p = .032) were significantly and positively associated with risk of LEA (R = −.46, p = .030). Conclusions: A significant proportion (59.1%) of players in the New Zealand national and U20 female football team are at risk of LEA. The positive and predictive relationship observed between mood disturbances, menstrual status, and risk of LEA suggests that regular monitoring of mood and menstrual cycle health may be used for the early identification of problematic LEA in national-level female footballers in New Zealand.

The purpose of this study was to evaluate change in bone mineral density (BMD), BMD percentile (BMDp), lean mass (LM), fat-free mass index, body fat percentage (BF%), and muscle size (mCSA) and quality (EI) in collegiate female gymnasts over a competitive season and characterize the impact of menarche on changes. Twenty gymnasts completed a validated survey to assess age of menarche. Body composition was assessed via whole-body dual-energy X-ray absorptiometry scans at pre- and postseason. mCSA and EI were determined from a panoramic ultrasound scan of the vastus lateralis. Pre- to postseason changes were evaluated using paired sample t tests, and strength of relationships between were analyzed via bivariate correlations and linear regression. Significant losses in body fat percentage (Δ -1.1 ± 1.9%; p = .022) and EI (Δ -5.0 ± 5.8 a.u.; p = .002) were observed. No significant changes were observed in BMDp, mCSA, BMD, LM, or fat-free mass index (p = .310–.869). Age of menarche (15.4 ± 1.5 years) was negatively correlated with Δ BMDp (r = −.454; p = .044) and Δ mCSA (r = −.658; p = .002), explaining 21% and 43% of variation in Δ BMDp and Δ mCSA, respectively. Positive outcomes of gymnastics training, such as gains in LM and mCSA, may be attenuated by delayed menarche, suggested by increased EI and decreased body fat percentage, despite no changes in mCSA or overall LM. These findings may indicate a higher priority of fat utilization within the muscle over muscle and bone growth. Considering menarche as a significant predictor for Δ mCSA, this lack of increase (despite improved EI), may signify increased injury risk resulting from team-specific training style or insufficient energy intake to support appropriate muscle growth.
本研究的目的是评估大学女子体操运动员在一个竞技赛季中骨矿物质密度（BMD）、骨矿物质密度百分位数（BMDp）、瘦体重（LM）、无脂肪质量指数、体脂百分比（BF%）、肌肉大小（mCSA）和质量（EI）的变化，并描述初潮对变化的影响。20 名体操运动员完成了一项评估初潮年龄的有效调查。在赛季前和赛季后，通过全身双能 X 射线吸收测量扫描评估身体成分。mCSA 和 EI 是通过侧阔肌全景超声波扫描确定的。使用配对样本 t 检验评估了季前和季后的变化，并通过双变量相关性和线性回归分析了两者之间的关系强度。观察到体脂肪百分比（Δ-1.1 ± 1.9%；p = .022）和EI（Δ -5.0 ± 5.8 a.u.；p = .002）显著下降。在 BMDp、mCSA、BMD、LM 或无脂肪质量指数方面未观察到明显变化（p = .310-.869）。初潮年龄（15.4 ± 1.5 岁）与 Δ BMDp（r = -.454; p = .044）和 Δ mCSA（r = -.658; p = .002）呈负相关，分别解释了 Δ BMDp 和 Δ mCSA 21% 和 43% 的变化。尽管 mCSA 或总体 LM 没有变化，但 EI 增加和体脂率降低表明，体操训练的积极成果，如 LM 和 mCSA 的增加，可能会因初潮推迟而减弱。这些发现可能表明，肌肉中脂肪的利用优先于肌肉和骨骼的生长。考虑到月经初潮是Δ mCSA的一个重要预测因素，尽管EI有所改善，但mCSA却没有增加，这可能意味着由于团队特定的训练方式或能量摄入不足导致受伤风险增加，从而无法支持适当的肌肉生长。

Olahraga mempunyai dampak positif dan negatif. Dampak positif olahraga diantaranya adalah meningkatkan kebugaran dan kesehatan, meningkatkan prestasi dan mencegah berbagai penyakit. Salah satu dampak negatif olahraga adalah terbentuknya senyawa oksidan yang memicu peristiwa stres oksidatif. Stres oksidatif terjadi karena sistem pertahanan antioksidan tubuh tidak mampu mengimbangi produksi radikal bebas. Stress Oxidative (SOD) dan Malondialdehyde (MDA) merupakan penanda aktivitas biologis dalam organisme yang terpapar stres oksidatif dari radikal bebas. Vitamin E adalah contoh antioksidan eksogen yang memiliki kandungan berbagai komponen antioksidan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian vitamin E sebelum aktivitas fisik terhadap konsentrasi malondialdehida plasma dan derajat kerusakan SOD akibat stres oksidatif pada manusia setelah aktivitas fisik. Rancangan penelitian menggunakan desain kelompok kontrol uji coba pasca laboratorium dengan tiga kelompok yang masing-masing terdiri dari sembilan subjek. Pengukuran dilakukan dengan mengambil 3 cm3 darah sebelum dan sesudah aktivitas fisik submaksimal. Dari uji post hoc diketahui terdapat perbedaan yang bermakna (0,001) antara kelompok kontrol dan kelompok K1 (dosis vitamin E 250 mg). Terdapat perbedaan bermakna (0,000) antara kelompok kontrol dan kelompok K2 (vitamin E dosis 500mg). Terdapat perbedaan bermakna (0,006) antara kelompok perlakuan K1 (vitamin E dosis 250mg) dengan K2 (vitamin E dosis 500mg). Simpulan dari penelitian ini adalah pemberian antioksidan eksogen (vitamin E dosis 250 mg dan dosis 500 mg) sebelum aktivitas fisik selama tujuh hari dapat menurunkan kadar SOD dan MDA plasma

Tujuan dari penelitian ini yaitu untuk mengetahui dampak penggunaan media audio visual terhadap penguasaan gerak pencak silat seni tunggal. Peneliti memilih menggunakan desain two group pretest-posttest design yang merupakan jenis penelitian eksperimen kuasi. Peneliti memilih atlet muda pada padepokan PSHT Landak yang dianggap memiliki kemampuan dalam melakukan gerak seni tunggal. dengan teknik pengambilan sempelnya yaitu total sampling yang berjumlah 30 orang. Pada penelitian ini menggunakan instrument tes yaitu pre test dan post test dan diakhiri dengan menggunakan from penilaian juri pencak silat kategori tunggal. Analisi data yang dipilih peneliti yaitu dengan uji t-test. Hasil dari penelitian yang dilakukan yaitu adanya dampak media audio visual terhadap hasil gerak pencak silat seni tunggal. Media audio visual dapat digunakan sebagai acuan/bahan materi diluar jam latihan, oleh karena itu disarankan kepada pelatih dan atlet pemula agar dapat penggunakan media audio visual sebagai bentuk variasi dan jam tambahan latihan
