AbstrakBegadang adalah suatu kebiasaan terjaga sampai larut malam dan tidur saat pagi datang.Orang yang sering begadang memiliki lebih besar risiko kesehatan yang buruk.Kebanyakan orang melakukan begadang karena mengerjakan pekerjaan saat malam,tetapi karena sering dilakukan tanpa disadari kegiatan saat begadang pun sudah tidak terlalu penting dan menjadi kebiasaan yang buruk yang dapat menimbulkan penyakit.Menurut Mahendra di dalam buku ‘Tubuh Anda Cerminan Kesehatan Anda (2010)’,“Begadang dapat memicu timbulnya berbagai penyakit dan menyebabkan rusaknya sistem imun tubuh.Apabila tidak beristirahat,organ-organ tidak dapat melakukan fungsinya dengan optimal.Hal ini akan menimbulkan masalah atau penyakit yang dapat menyerang tubuh.Hal ini membuktikan bahwa sebenarnya begadang bukan lah kebiasaan yang bagus jika dipaksakan untuk dilakukan saat tubuh sedang kelelahan.Sedangkan dampak begadang menurut Handoyo dalam buku ‘Aplikasi Olah Nafas (2005, h.30)’,“Begadang dapat menguras tenaga yang membuat tubuh menjadi lemah.Saat lelah tubuh akan lebih terasa lebih mudah cepat pegal dan tubuh ingin cepat cepat beristirahat kembali.Maka dari itu rasa lelah inilah yang akan membuat sulit berkonsentrasi,dengan kata lain tidak hanya menyerang fisik,begadang juga dapat menyerang psikis.Untuk itu pintar-pintarlah dalam mengatur pola tidur.

Background: Preseason training optimises adaptations in the physical qualities required in rugby union athletes. Sleep can be compromised during periods of intensified training. Therefore, we investigated the relationship between sleep quantity and changes in physical performance over a preseason phase in professional rugby union athletes. Methods: Twenty-nine professional rugby union athletes (Mean ± SD, age: 23 ± 3 years) had their sleep duration monitored for 3 weeks using wrist actigraphy. Strength and speed were assessed at baseline and at week 3. Aerobic capacity and body composition were assessed at baseline, at week 3 and at week 5. Participants were stratified into 2 groups for analysis: <7 h 30 min sleep per night (LOW, n = 15) and >7 h 30 min sleep per night (HIGH, n = 14). Results: A significant group x time interaction was determined for aerobic capacity (p = 0.02, d = 1.25) at week 3 and for skinfolds at week 3 (p < 0.01, d = 0.58) and at week 5 (p = 0.02, d = 0.92), in favour of the HIGH sleep group. No differences were evident between groups for strength or speed measures (p ≥ 0.05). Conclusion: This study highlights that longer sleep duration during the preseason may assist in enhancing physical qualities including aerobic capacity and body composition in elite rugby union athletes.

Abstract The aim of this study was to compare the kinematic characteristics of tennis matches between red clay and hard courts in young tennis players. Eight young tennis players performed two tennis matches on different court surfaces. The match activities were monitored using GPS units. The distance covered in different velocity ranges and the number of accelerations were analyzed. The paired t test and inference based on magnitudes were used to compare the match physical performance between groups. The total distance (24% of difference), high-intensity running distance (15 - 18 km/h) (30% of difference), the number of high-intensity activities (44% of difference), the body load (1% of difference), and accelerations >1.5 g (1.5-2 g and >2 g 7.8 and 8.1 % of difference, respectively) were significantly greater in clay court than hard court matches (p < 0.05). Matches played on the red clay court required players to cover more total and high-intensity running distances and engage in more high-intensity activities than the matches played on the hard court. Finally, on the clay court the body load and the number of accelerations performed (>1.5 g) were possibly higher than on the hard court.

Voluntary Food Intake

ABSTRACTThe level of body reserves in first-litter sows was manipulated by giving gilts one of three levels (high (H), medium (M) or low (L)) of food from selection (44 kg live weight) to parturition. The aim of this experiment was either to maintain or to mobilize these reserves during lactation (31·4 days) by feeding sows to appetite (high (H)) or 2·0 kg/day (low (L)).When the level of body reserves was increased prior to farrowing (171 kg live weight, 32 mm backfat) sows had a lower voluntary food intake during lactation than those animals that farrowed with a low level of body reserves (126 kg live weight, 20 mm backfat) (H-H v. L-H, 3·4 v. 4·9 kg/day; P < 0·001). Both groups had a normal return to oestrous activity after weaning (mean interval between weaning and mating of 14 days) but the heavier animals mobilized more of their body reserves (H-H −30·7 kg live weight, -4·3 mm backfat; L-H -3·6 kg live weight +0·9 mm backfat; P < 0·001). When food intake during lactation was restricted to 2·0 kg/day the interval between weaning and mating was increased by 50% regardless of the level of body reserves present at farrowing. For the same animals, there were insufficient body reserves to support milk production at the same level as for those animals given food t o appetite.

O objetivo deste estudo foi verificar o efeito agudo de uma sessão de alongamento estático sobre a curva glicêmica em idosas fisicamente inativas não diabéticas. Avaliou-se as curvas glicêmicas nos tempos 0 (jejum de 12 h), 30 min, 60 min, 90 min e 120 min, após a ingestão de 75 g de dextrose, de 16 idosas em dois momentos distintos: Teste Basal (TB) sem a realização de alongamento e Teste Experimento (TE) sete dias após, com a realização do alongamento. A glicemia média aos 60 min, 90 min e 120 min no TE foi menor que no TB, porém as diferenças não foram significantes (p ≤ 0,05). Considerando o ponto 30 min como referência, a variação média da glicemia entre os testes nestes tempos foi de aproximadamente de 15 mg/dL, sendo significante no tempo 60 min (p = 0,011). Uma sessão de alongamento não estimulou o aumento do consumo de glicose na população estudada.Palavras-chave: exercícios de alongamento muscular, pessoa idosa, teste de tolerância à glucose.

In this study, a lab-scale Partial Nitritation Sequencing Batch Reactor (PNSBR) was implemented for treating high-ammonium old landfill leachate to yield an appropriate NO2—N/ NH4+-N ratio from 1/1 to 1.32/1 mixture as a pretreatment for subsequent Anammox. The objective of this study was to determine the optimal hydraulic retention time (HRT) at different influent ammonia concentrations for 210 days. The experimental results showed that with the influent ammonia concentrations of 500, 1000, 1500 and 2000 mg/L, HRT is 12 h, 21 h, 30 h and 48 h, respectively. The range of free ammonia (FA) concentration from 17 to 44 mg/L completely inhibited nitrite oxidizing bacteria (NOB) for long time operation. The COD removal efficiency was very low (6±2) %.

Pentacyclic triterpenes (PTs) are commonly found in medicinal plants with well-known antiparasitic effects. Previous research on C-3 and C-27 triterpenic esters showed effective and selective in vitro antiparasitic activities and in vivo effectiveness by parenteral routes. The aim of this study was to determine triterpenic esters’ stability in different biological-like media and the main microsomal degradation products. An HPLC-PDA method was developed and validated to simultaneously analyze and quantify bioactive triterpenic esters in methanol (LOQ: 2.5 and 1.25–100 µg/mL) and plasma (LOQ: 5–125 µg/mL). Overall, both triterpenic esters showed a stable profile in aqueous and buffered solutions as well as in entire plasma, suggesting gaining access to the ester function is difficult for plasma enzymes. Conversely, after 1 h, 30% esters degradation in acidic media was observed with potential different hydrolysis mechanisms. C-3 (15 and 150 µM) and C-27 esters (150 µM) showed a relatively low hepatic microsomal metabolism (<23%) after 1 h, which was significantly higher in the lowest concentration of C-27 esters (15 µM) (>40% degradation). Metabolic HPLC-PDA-HRMS studies suggested hydrolysis, hydroxylation, dehydration, O-methylation, hydroxylation and/or the reduction of hydrolyzed derivatives, depending on the concentration and the position of the ester link. Further permeability and absorption studies are required to better define triterpenic esters pharmacokinetic and specific formulations designed to increase their oral bioavailability.
