Horse riding (HR) is a sport harmonized with rider and horse. HR is renowned as an effective sport for young and old women and men. There is rare study regarding comparison between elite horse riders and amateurs. We aimed to investigate comprehensive ranges of parameters such as change of lactate, heart rate, calorie, VO2max, skeletal muscle mass, body water, body fat, etc between amateurs and professionals to emphasize HR not only as a sport training but also as a therapeutic aspect. We performed 3 experiments for comparing physical fitness, body compositions, lactate value, heart rate and calorie consumption change before and after riding between amateurs and elites. Around 3 yr riding experienced elites are preeminent at balance capability compared to 1 yr riding experienced amateurs. During 18 min horse riding, skeletal muscle mass and body fat were interestingly increased and decreased, respectively. Lactate response was more sensitive in elites rather than amateurs and its recovery was reversely reacted. Exercise intensity estimated from heart rate was significantly higher in elites (P<0.05). The similar pattern of calorie consumption during riding between amateurs and elites was shown. Horse riding possibly induces various physiological (muscle strength, balance, oxidative capability, flexibility, and metabolic control) changes within body and is thus highly recommended as combined exercise for women, children, and aged as therapeutic and leisure sport activity.
The aim of this study was to provide a detailed comparison of physique and physical fitness differences among Track and Field groups. The male athletes participating in this study consisted only of South Korean national track and field athletes. The Korean national athletes were divided into four groups (long-distance runner, sprinter, jumper, thrower). The long-distance runner group (n=7) consisted of three male marathoners and four male race walkers. The sprinter group (n=7) consisted of five male 100m athletes and two male hurdlers. The jumper group (n= 7) consisted of 2 male high jumpers, 2 male long jumpers, and 3 male pole vault athletes. The thrower group (n=8) consisted of 2 male shot put athletes, two male javelin throwers, 2 male discus throwers and 2 male hammer throwers. This study was designed to investigate the effects of physique (height, weight), muscular strength (grip strength), muscular endurance (push-ups, sit-ups), agility (side step), power (vertical jump), cardiopulmonary endurance (maximal oxygen uptake, Anaerobic Threshold %VO 2 max, rest heart rate), and flexibility (sit and reach). A one-way ANOVA was performed for the mean difference test among track and field athlete groups. A post hoc test method was conducted through the Scheffe Test. The results are as follows. The thrower athlete group showed significantly better results in weight, muscular strength (grip power) than the sprinter athlete group, long-distance runner group and the jumper athlete group. The long-distance runner group showed significantly better result in VO 2 max and AT (Anaerobic Threshold) than the sprinter group, thrower group and the jumper group. The sprinter group showed significantly better results in power (vertical jump) than the other three groups. There was no significant difference among the groups in the results for muscular endurance (push-up, sit-up), flexibility (sit and reach) and agility (side steps). In conclusion, the South Korean national long-distance runner group (VO 2 max: 72.6ml/kg/min, ATVO 2 max: 54ml/kg/min) was superior to the other three groups in cardiovascular endurance. The sprinter's group (vertical jump: 63.1cm) was superior to the other three groups in power. The thrower group (weight: 97kg, grip strength: 81kg) was superior to the other three groups in muscular strength and was heavier than the other groups. Korean national track & field athletes showed the characteristics of cardiovascular endurance, muscular strength, and power in a detailed analysis of items. No differences were found in muscular endurance, flexibility, and agility. Differences in physique and physical fitness among detail event groups of Korean national athletes were in accordance with previous studies. In future studies, the sample size should be increased to improve the reliability and validity of the study results.
PURPOSE: This study aimed to develop prediction equations for estimating the physical fitness age (PFA) of Korean adults in young (19-40 years), middle (41-64 years), and old (65-80 years) age groups.METHODS: Data from 122,842 individuals who participated in Korea National Physical Fitness Survey and National Fitness 100 from 2009 to 2014 were collected. Body composition, muscular strength, muscular endurance, flexibility, cardiorespiratory endurance, agility, power, balance, and coordination were measured. Pearson’s correlation and stepwise regression analyses were used to analyze the data.RESULTS: The equations were as follows: PFA for young males=22.321 −.088 (20-m PACER)+.317 (body mass index [BMI]); PFA for young females=24.486 −.143 (20-m PACER)+.304 (BMI); PFA for middle-aged males=66.644 −.044 (standing long jump) −.069 (20-m PACER) – .201 (weight) −.075 (modified sit-ups)+.269 (10-m shuttle run)+.320 (BMI); PFA for middle-aged females=66.814 −.098 (standing long jump) −.113 (modified sit-ups); PFA for older males=84.795+.093 (figure-of-8 walk) −.100 (chair standing) −.122 (weight) −.102 (relative grip strength) −.060 (sit-and-reach)+.147 (3-m up-and-go); and PFA for older females=80.577+.097 (figureof-8 walk)+.306 (3-m up-and-go) −.280 (weight) −.088 (relative grip strength) −.069 (sit-and-reach)+.393 (BMI) −.088 (chair standing) −.011 (2-min step-in-place).CONCLUSIONS: Our prediction equations for PFA can be used as a tool to prescribe sex- and age-appropriate exercise program and to verify the effect of the application of the exercise program by comparing pre -and post-PFA.
Background: During most COPD exacerbations, patients continue to live in the community but there is little information on changes in activity during exacerbations due to the difficulties of obtaining recent, prospective baseline data. Methods: Patients recorded on daily diary cards any worsening in respiratory symptoms, peak expiratory flow (PEF) and the number of steps taken per day measured with a Yamax Digi-walker pedometer. Exacerbations were defined by increased respiratory symptoms and the number of exacerbations experienced in the 12 months preceding the recording of daily step count used to divide patients into frequent (> = 2/year) or infrequent exacerbators.
