The purpose of this study was to compare the concentration of and the time to peak blood lactate following three 90-s cycle ergometer tests--intermittent all-out (Int-A), continuous all-out (Cont-A), and continuous constant (Cont-C), and to compare group peak lactate to blood lactate at individual peak time. Eight fingertip blood samples were drawn between 1 and 12min post-exercise. Subjects were university hockey players (n = 19) and physical education students (n = 19). The two all-out tests had a higher peak concentration than the Cont-C test (P $<$ 0.05). The Int-A test had an earlier peak than the two continuous tests (P $<$ 0.05) but this difference vanished if peak time was measured from the onset of the tests. A number of sampling times had lactate concentrations similar to the individual peak concentration (P $<$ 0.05): (1) 1, 2, 3, and 4min for Int-A; (2) 2, 3, 4, 5, and 6min for Cont-A; (3) 2 and 4min for Cont-C.

Tyrimo objektas – tiriamųjų liemens raumenų statinės ištvermės, pusiausvyros, lankstumo rodiklių pokytis. Tyrimo problema – pastaruoju metu greitai daugėja gyvenimo būdo sąlygotų lėtinių sutrikimų. Geriausias būdas prieš juos kovoti – ne invazinis gydymas bei prevencija, todėl kineziterapeutai yra geriausioje padėtyje užpildyti šią kritinę nišą sveikatos apsaugoje. Vienas geriausių prevencijos būdų yra fizinis aktyvumas. Fizinis aktyvumas daugumai asocijuojasi su sportu, tačiau sportas neatsiejamas nuo traumų ir ne visiems yra priimtina sportinė veikla. Žmonės vis intensyviau ieško alternatyvių sveikatos stiprinimo būdų. Joga vis labiau plinta tiek visoje Europoje, tiek Lietuvoje. Pripažįstama, kad joga taip, kaip ir fizinis aktyvumas, turi didelę naudą tiek fizinei, tiek psichinei sveikatai. Tačiau pagrinde tiriamas jogos poveikis pagyvenusiems, ar rečiau vidutinio amžiaus žmonėms. Verta ir aktualu nustatyti jogos poveikį vaikų fizinei būklei. Tyrimo tikslas – nustatyti jogos pratimų poveikį 6-9 klasių moksleivių fiziniam pajėgumui. Tyrimo uždaviniai: 1. Nustatyti jogos pratimų poveikį tiriamųjų pilvo, nugaros ir šoninių liemens raumenų statinei ištvermei, bei santykiams tarp jų. 2. Nustatyti jogos pratimų poveikį tiriamųjų pusiausvyrai. 3. Įvertinti jogos pratimų poveikį tiriamųjų lankstumui. 4. Palyginti rezultatus tarp tiriamosios ir kontrolinės grupių tiriamųjų. Tyrimo metodai: testavimas (buvo naudojami testai pilvo, nugaros ir šoninių liemens raumenų statinei ištvermei...

Background – there is noticeable increase of lifestyle chronic conditions in recent times. The best way to fight them is non-invasive treatment and prevention, so physical therapist are in the best position to fill this critical health care niche. Physical activity is one of the best possible prevention. Physical activity is related to sports for majority people, sports are related to injuries and is not acceptable for everyone. People are searching for alternative health promotion ways. Yoga is getting more and more popular in Europe and in Lithuania. Yoga is acknowledged to be beneficial for health. It is necessary to asses effect of yoga on physical fitness in schoolchildren. The aim – assess effect of yoga on physical fitness in schoolchildren of 6-9 grades. Tasks: 1. Assess effect of yoga on static endurance of core muscles and the ratios between them. 2. Assess effect of yoga on balance. 3. Assess effect of yoga on flexibility. 4. Compare the results between groups. Methods: testing (tests for static endurance of core muscles, balance and flexibility). Statistical analysis (SPSS Statistics 17.0 and Microsoft excel were used to make the calculations). Hypothesis: yoga will improve physical fitness of schoolchildren of 6-9 grades. Conclusions: 1. The effect of yoga was statistically meaningful on static endurance of core muscles. The effect... [to full text]

The purpose was to examine the effect of body mass and body composition on the mean power output in the 30 second Wingate cycling test at five resistance settings. Forty females (X = 22 years), were divided into four groups based on body mass and the sum of five skinfolds. The Wingate test was performed at the resistance settings of 0.075, 0.080, 0.085, 0.090, and 0.095 kp/kg body weight. A 3-way ANOVA (mass, skinfolds, resistance settings) indicated that: (1) mean power (W/kg) was similar for low and high mass groups; (2) the low sum of skinfolds group had a significantly higher (p $<$ 0.02) mean power output than the high sum of skinfolds group; and (3) at resistance settings of 0.080, 0.085, 0.090, and 0.095 (kp/kg) the low sum of skinfolds group had a higher (p $<$ 0.05) mean power score than the high sum of skinfolds group at equivalent resistance settings.

The purpose of this study was to examine power output and fatigue from power-time curves of cycle ergometer and isokinetic dynamometer tests. Fifteen physically active female university athletes performed a 45 s cycle ergometer test at resistances of 0.075, 0.085, and 0.095 kp/kg bw, as well as a 45 s and a 3 repetition isokinetic flexion and extension test at velocities of 60, 180, and 300$ sp circ$/s. Results revealed that peak power, mean power (W and W/kg), and fatigue (W/kg) were highest at the 0.095 kp/kg bw resistance and lowest at the 0.075 kp/kg bw resistance. Significant differences among the three cycle ergometer conditions existed for peak power, mean power, and fatigue. Peak power and mean power (W and W/kg) were highest at 300$ sp circ$/s and lowest at 60$ sp circ$/s. Results revealed significant differences among the isokinetic dynamometer conditions for peak and mean power. Mean power output (W) was significantly correlated (range of r = 0.56 to r = 0.74) for the cycle ergometer and the isokinetic dynamometer test conditions.

<p>Chronic diseases pose public health concerns globally with an increasing trend in developing countries. The development of interventions to minimize or prevent the burden associated with chronic diseases has therefore become a necessity. In 2002 the School of Public Health of the University of the Western Cape developed a health club intervention in Khayelitsha. This intervention focused on promoting healthy lifestyles, particularly improved diet and physical activity. The objectives of this study was to determine whether members were more physically active than non-members and to determine whether members made healthier dietary choices than non-members.</p>

This study aimed to document the effects of regular exercise and physical activity on the aged. Subjects (n=S8) over the age of sixty-five participated in the study. All subjects were patrons from various retirement centers of the DAFTA organization (Durban Association for the Aged). The subjects completed a PAR-Q and informed consent form, which allowed the eligible to participate in the study. A pre and post-test battery was administered to measure the following parameters; body mass, height, girth measurement, agility and dynamic balance, muscle strength and endurance, flexibility, co-ordination, dynamic grip strength and aerobic capacity. During the experimental period the subjects engaged in a structured intervention exercise programme of 30 weeks. The intervention programme composed of games, walking, stretching, flexibility and resistance training exercises aimed at improving the following fitness components; agility and dynamic balance, strength, flexibility, co-ordination and aerobic capacity. Inferential and differential statistical methods were employed in order to analyzethe data. The study indicated that regular exercise and physical activity positively impacted the senior citizens' functional capacity and improved their quality of life (p<O.OS). The intervention programme served its purpose well. There are, however, many changes to be made to suit specific institutions and individuals. To ensure similar positive effects, follow-up exercise programmes would be necessary. / Thesis (M.Sport Sc.)-University of Durban-Westville, 2002.
