A simple and quick sensitivity analysis method for methane isotopologues detection with GOSAT-TANSO-FTS
Measurements of methane isotopologues can differentiate between different source types, be
they biogenic (e.g. marsh lands) or abiogenic (e.g. industry). Global measurements of these
isotopologues would greatly benefit the current disconnect between ‘top-down’ (knowledge from
chemistry transport models and satellite measurements) and ‘bottom-up’ (in situ measurement
inventories) methane measurements. However, current measurements of these isotopologues are
limited to a small number of in situ studies and airborne studies. In this paper we investigate the
potential for detecting the second most common isotopologue of methane (13CH4) from space using
the Japanese Greenhouse Gases Observing Satellite applying a quick and simple residual radiance
analysis technique. The method allows for a rapid analysis of spectral regions, and can be used
to teach university students or advanced school students about radiative transfer analysis. Using
this method we find limited sensitivity to 13CH4, with detections limited to total column methane
enhancements of >6%, assuming a desert surface albedo of >0.3
Assessment of reliability in isokinetic testing among adolescent basketball players
Background. The reproducibility of day-to-day testing of isokinetic concentric and eccentric muscular actions among adolescent basketball players aged 14 to 16 years and relationships of mean within-subject variation in two isokinetic testing sessions with chronological age, biological maturation (estimated age at peak height velocity), training experience, body size, lower-body morphology, and initial strength performance were evaluated.
Material and Methods. The sample included 27 basketball players who completed replicate test sessions of 5 repetitions of reciprocal concentric and eccentric knee extensions and flexions at 60 degrees s(-1). A randomly selected subsample of 8 players completed a third testing session to confirm reliability estimates.
Results. Coefficients of variation (CV) between sessions 1 and 2 ranged from 8.1% to 17.4%, and intraclass coefficients (ICCs) ranged from 0.72 to 0.89. For sessions 1 and 3, CVs ranged from 3.9% to 6.0%, and ICCs ranged from 0.95 to 0.99. The initial level of strength of eccentric knee flexion (r=-0.43) and eccentric knee extension (r=-0.42) were correlated (P<0.05) with eccentric knee extension within-variation between two sessions. Training experience (r=-0.37, P<0.05) and initial values of concentric knee flexion (r=-0.62, P<0.01) were correlated with concentric knee flexion within-subject differences. Within-subject variation of eccentric knee extension was correlated (P<0.05) with chronologic age (r=0.41), estimated age at peak height velocity (r=-0.38), body size (r=0.41 to 0.47), and leg volume (r=0.39).
Conclusions. Familiarization sessions may improve the reliability of concentric and eccentric knee isokinetic strength testing at 60 s(-1) in adolescent basketball players. Age, maturity status, and training experience of young athletes should be considered when testing knee isokinetic strength at 60 degrees s(-1)
Developmental fitness curves: Assessing sprint acceleration relative to age and maturity status in elite junior tennis players
Background The influence of maturity-status on athletic performance is reasonably well-documented. Methodological and practical issues of assessment and lack of longitudinal data have impacted the success of various models. Aim To develop age- and sex-specific developmental curves for sprint acceleration in elite youth tennis players and to address variation in performance relative to chronological and biological age. Subjects and methods Measures of acceleration were available for 3120 elite youth tennis players aged 8–15 years attending National and Regional Talent Identification days. Variation in acceleration by chronological and estimated biological ages was evaluated in corresponding data for an independent sample of elite youth players 8.9 to 15.1 years of age. Results Acceleration varied as a function of chronological and biological age relative to developmental curves. Early maturing males and females had significantly poorer performances when acceleration was considered relative to biological age. Significant discrepancy in percentiles relative to biological versus chronological ages was also evident between early and late maturing players of each sex. Conclusion Evaluating performance relative to developmental curves and maturity status may be a practical means of monitoring long-term athlete development in tennis
