“…The measurement of anaerobic capacity, i.e. peak power and mean power by Wingate test was initially presented by Ayalon et al (1974). The present finding was not similar to a study by Witzke and Snow (1999) who showed that leg power assessed by Wingate test was correlated with BMD at all sites except the lumbar spine.…”

Problem statement: Data on bone health status, muscular peak torque (an indicator of muscular strength) and power is still lacking in non-active young Malays. Moreover, no study has been undertaken to investigate the association between bone health and anaerobic capacity in the Malay population. Hence, the present study was designed to address the paucity of this information. Approach: Young, healthy Malay females (n=33) and males (n=33) university students aged 18-25 years old were recruited for this study. The quantitative ultrasound measurements of bone speed of sound (SOS) in the legs were measured using a bone sonometer. Muscular peak torque of knee extension and flexion at 60 0 .s -1 and 180 0 .s -1 were measured using a BIODEX isokinetic dynamometer. Anaerobic capacities of the participants were determined via the Wingate anaerobic test. Purpose: To investigate the relationships of lower limbs' quantitative ultrasound measurement of the bones with muscular peak torque and anaerobic capacities in Malay university students. Results: Correlation coefficient (r) between non-dominant tibial SOS and muscular peak torque at 60 0 .s -1 and 180 0 .s -1 in female participants was 0.448 (p=0.009) and 0.388 (p=0.026) respectively. In males, moderate correlation was found between nondominant tibial SOS and muscular peak torque at 180 0 .s -1 knee flexion (r=0.419, p=0.015). Conclusions: There were moderate correlations (p<0.05) between muscular peak torque, mean power and peak power in the male participants. Nevertheless, no significant correlations were observed between tibial SOS and anaerobic capacities of mean power and peak power in both females and males. There were moderate relationships between quantitative ultrasound measurement of the bones with muscular strength, but not with anaerobic capacities in university students.

“…Initially, subjects exercised at maximum intensity for a brief period (Ayalon et al, 1974) to determine a peak heart rate (HR) response while swimming, cycling, and running in a random order. In the final three visits, subjects performed, in a randomized order, 60-min "all out" swimming, cycling, and running exercise trials.…”

AbstractWe compared the response of high-sensitivity cardiac troponin T (hs-cTnT) after 60 min of swimming, running, and cycling in well trained triathletes. The maximal increase in hs-cTnT was similar in all exercise bouts (swimming 453%, cycling 349% and running 471%) although there was substantial individual variability in peak hs-cTnT. The post-exercise kinetics for hs-cTnT were consistent. The change in hs-cTnT was correlated between trials. In all trials hs-cTnT had largely returned to baseline levels 24 h post-exercise. In summary, an increase in hs-cTnT was apparent in all triathletes independent of exercise mode and despite variable peak data the consistent kinetics over 24 h post-exercise would suggest this represents a physiological phenomenon.

“…The test consisted of ten 10-s cycling sprints with eight 30-s passive recovery periods immediately before the 2nd, 3rd, 4th, 6th, 7th, 8th, 10th sprints, respectively, and two 360-s passive recovery periods immediately before the 5th and 9th sprints, respectively. All cycling sprints were performed with a resistive load [N] of 0.075·BM·9.81 -1 (Ayalon et al 1974). Subjects were instructed to pedal as many revolutions as possible during cycling sprints.…”

Abstract:The purpose of this study was to determine the effect of oral administration of sodium bicarbonate (NaHCO 3 ) on surface electromyogram (SEMG) activity from the vastus lateralis (VL) during repeated cycling sprints (RCS). Subjects performed two RCS tests (ten 10-s sprints) interspersed with both 30-s and 360-s recovery periods 1 h after oral administration of either NaHCO 3 (RCS Alk ) or CaCO 3 (RCS Pla ) in a random counterbalanced order. Recovery periods of 360 s were set before the 5th and 9th sprints. The rate of decrease in plasma HCO 3 -concentration during RCS was significantly greater in RCS Alk than in RCS Pla , but the rates of decline in blood pH during the two RCS tests were similar. There was no difference between change in plasma lactate concentration in RCS Alk and that in RCS Pla . Performance during RCS Alk was similar to that during RCS Pla . There were no differences in oxygen uptake immediately before each cycling sprint (preV ． O 2 ) and in SEMG activity between RCS Alk and RCS Pla . In conclusion, oral administration of NaHCO 3 did not affect SEMG activity from the VL. This suggests that the muscle recruitment strategy during RCS is not determined by only intramuscular pH.
