An obesrvational study to compare bala in Adana and visarga kaala with respect to physiological parameters

Introduction - Ayurveda gives utmost importance to the maintenance of positive health. Health and longevity in turn depends on bala or inherent strength of the individual. Bala is different in different seasons. Bala is examined as the capacity to do exercise, which is indicative of physical power of an individual. If the reflection of variation of bala on the basis of hematological parameters is identified, then it will provide many possibilities to modify the diet and lifestyle of healthy individuals in order to maintain health in all seasons. This work is a humble effort to analyze the seasonal variations in bala with respect to physiological objective parameters in the settings of Govt. Ayurveda medical college, Kannur, Kerala, India. Methods - In this study 30 healthy individuals between the age group of 20-30 were selected having similar vyayamasakthi- ie, based on the time taken to attain ardhasakthi lakshanas in treadmill test. First assessment was done in adanakaala. Their basic details, dasavidha pareeksha were taken before treadmill test. After 3 days of treadmill test, blood investigations were analyzed. The same procedure was done in visarga kaala also.Results - On the basis of analysis, the bala assessed by vyayamasakthi in visarga kaala was increased than adana kaala. Hemoglobin and HDL cholesterol were increased and serum calcium was decreased in visarga kaala. Considering vital parameters, increase in pulse rate, heart rate, systolic and diastolic BP was noticed in visarga kaala; all within physiological limits. Discussion – Bala was decreased in adana kaala due to the intensity of sunrays and intense dry wind. It causes decreased time to attain the ardhasakthi lakshana. Sweat occurs early. The bala was higher in visarga kaala compared to adaana kaala.

RELEVANCE OF VO2max CONSUMPTION IN ELITE BULGARIAN TAEKWONDO COMPETITORS

The aim of this study was to determine aerobic fitness through the VO2max treadmill test of elite Bulgarian taekwondo players with international results, and to determine whether the aerobic system had an effect upon the sports result in taekwondo. Fourteen elite taekwondo athletes, members of the Bulgarian national team (8 male and 6 female) were tested using a continuous progressive treadmill test. Physiological characteristics such as maximal oxygen uptake(VO2max), blood lactate and heart rate were measured. The male athletes recorded 58.2±3.4 ml kg–1 min–1 and the female 46.0±2.8 ml kg–1 min–1. The lactate level reached its highest at the 6’ after the VO2max with results for the males of 11.5±3.7 (mmol l-1) and 9.9±4.1 (mmol l-1) for the females respectively. A comparison between our results, regarding VO2max and previously reported was made using the One-way Anova for independent samples. It showed no significant difference between the male subjects (58.2±3.4 versus 60.7±3.3 ml kg(-1) min(-1), p>.05) and significant difference between the female ones (46.0±2.8 versus 49.8±2.8 ml kg(-1) min(-1), p<.05). Investigated also was the number of kicks executed by the winner of -49 kg weight category and her direct opponents during the 2019 Grand Prix Sofia. It was discovered that the winner kicked an average of 86.25 times per match and her kicks during the Grand Prix Sofia accumulated to 390 in total. It is our conclusion that the aerobic fitness does not play a significant role in taekwondo.

Validity of the 20 Meter Multi-Stage Shuttle Run Test (MSSRT) In Predicting VO2 Max

The purpose of this study was to investigate the validity of the 20 meter multi-stage shuttle run test (MST) in predicting VO2max compared to the directly measured reading from the laboratory. 4 male participants, who were diverse in terms of their ages and who were active physically, performed the MST and an incremental treadmill tests. Predicted VO2max values were obtained for the MST based on their stages and shuttles and actual VO2max values were obtained from the laboratory treadmill test. Results showed that all predicted VO2max values for the MST over-predicted that of the actual VO2max values from the laboratory test. This study seems to suggest that there is no validity in the MST in predicting VO2max of an individual as compared to the actual VO2max values from the laboratory.

The state of cardiorespiratory system in female students with idiopathic arterial hypertension under treadmill training

Annotation. One of the most widespread pathogenic condition, among young women, is idiopathic arterial hypertension which significantly worsen the life condition, learning abilities and in future can lead to the development of arterial hypertension, ischemic heart disease, complicate course of the pregnancy and delivery. The aim of the research was to examine the functional state of cardiorespiratory system in female students of 1-3rd year of high school with the signs of idiopathic arterial hypertension under the fixed stress- test. The main group consisted of 32 female students of 1-3rd year of high school with idiopathic arterial hypertension. The control group was formed from almost healthy female students from the same years of study. The treadmill (Biomedical Systems), due to Bruce protocol, was used for estimating the level of tolerance to physical pressure. To assess the degree of reliability of the results of the study used a variational-statistical method of analysis of the results using a package of statistical programs Statistica V. 10 (USA) and the recommendations of O. Yu. Rebrova (2002). Under the treadmill test it was revealed the decrease of tolerance to physical pressure in female students from the main group on 31,24% (р<0,05), in comparison to the MET numbers got in the control group (37,11±2,16) ml/kg/min. Under stress-test reliable increase of heart rate in control group was observed after 6-8 minutes of training, in female students from control group the same reaction was observed after 3-5 min of training without its further increase. The increase of SBP in the main group at the peak of training was (20,88±3,12)%, in the control group – this index was completely higher (27,88±3,36)% (р<0,01). After the finishing of the stress test in the female students of the main group the duration of their heart rhythm and arterial pressure reviving was (9,85±1,22) min., that overcame the result got in control group (6,24±0,67) min. Thus, the treadmill test allows exactly reveal the level of cardiorespiratory system adaptation to physical pressure, aerobic capacity in young women with the signs of idiopathic arterial hypertension.

Reliability and Validity of the SHFT Running Power Meter

The SHFT device is a novel running wearable consisting of two pods connected to your smartphone issuing several running metrics based on accelerometer and gyroscope technology. The purpose of this study was to investigate the reliability and validity of the power output (PO) metric produced by the SHFT device. To assess reliability, 12 men ran on an outdoor track at 10.5 km·h−1 and 12 km·h−1 on two consecutive days. To assess validity, oxygen uptake (VO2) and SHFT data from eight men and seven women were collected during incremental submaximal running tests on an indoor treadmill on one to four separate days (34 tests in total). SHFT reliability on the outdoor track was strong with coefficients of variance (CV) of 1.8% and 2.4% for 10.5 and 12 km·h−1, respectively. We observed a very strong linear relationship between PO and VO2 (r2 = 0.54) within subjects, and a very strong linear relationship within each subject within each treadmill test (r2 = 0.80). We conclude that SHFT provides a reliable running power estimate and that a very strong relationship between SHFT-Power and metabolic rate exists, which places SHFT as one of the leading commercially available running power meters.

Relationship of critical speed derived from a 10-minute submaximal treadmill test to 5-km and 10-km running performances

It has been shown that the critical speed (CS) predicted from a perceptually self-regulated 10-min submaximal treadmill test (T10) is reliable and closely matches the CS estimated from conventional methods. To assess the relationship between the T10 and 5-km and 10-km running performances, 36 recreational runners (mean SD: age: 32.2 ± 6.2 years, height: 173.2 ± 7.3 cm, weight: 70.9 ± 8.8 kg, V̇O2max: 53.3 ± 6.1 mL.kg-1.min-1) performed a ramp incremental test and two T10 tests (the first as a familiarization trial). Results showed that the T10 CS (3.9 ± 0.44 m.s-1) was significantly correlated with runners’ last 6 months best performances in 5-km (20.3 ± 2.7 min; r = -0.90) and 10-km (42.7 ± 5.7 min; r = -0.91), the V̇O2max (r = 0.75), the speed associated with the gas exchange threshold (vGET: 3.38 ± 0.36 m.s-1; r = 0.76), the speed associated with the second ventilatory threshold (vVT2: 4.15 ± 0.49 m.s-1; r = 0.84), and the speed associated with the V̇O2max (vV̇O2max: 4.78 ± 0.54 m.s-1; r = 0.87). Moreover, 79% and 83% of the variance in 5-km and 10-km performances could be explained solely by the CS predicted from the T10. Results evidenced the strong relationship and practical performance relevance of the T10 CS test. Novelty: • Critical speed derived from a 10-min submaximal treadmill test (T10) is significantly correlated with 5-km and 10-km running performances • The T10 critical speed test may represent a useful tool for assessing running performance capabilities
