“…Most studies of cycling power in children and in adults have used the popular 30-s WAnT. Few authors have reported the reproducibility of PP output measurements [ 5 , 14 ]. This study hypothesized that maximal cycling power computed from the OL derived from the parabolic relationship between Fb and power output does not require a familiarisation session.…”

“…Results confirmed that estimated PP-OL obtained from the FVT protocol seemed to be reasonable reproducible in adult non-elite athletes. A previous study [ 5 ] examined reproducibility of 10-s PP measured in cycling effort against different Fb’s in male young adult athletes (n = 48) and reported a TEM of 59 Watt (%CV = 5.52%; ICC = 0.951, 95% CI: 0.912; 0.972). Early studies using the WAnT recommended the determination of PP output over a 5-s period and assumed that this would reflect alactic anaerobic performance [ 15 ].…”

“…Subsequent research in adults evidenced a substantial increment in the concentration of muscle lactate during the first seconds of the maximal effort [ 16 ]. In addition, mean values of PP were relatively stable when obtained from sampling rates of 50 Hz or while corresponding to a sampling rate of 1 Hz [ 5 ]. However, the FVT has assumptions such as the quasi-linear Fb velocity and parabolic Fb for the determination of PP-OL and V-OL, and potential error of measurement associated to Fb’s would theoretically affect the interpolation of PP-OL and V-OL [ 14 ].…”

“…Consequently, generalization of conclusions should be done with caution and the recommendations of the present study would be valid for non-elite athletes within the specific characteristics for sex, chronological age, training experience, body size and composition. The principal disadvantage of the FVT is probably the amount of time needed for completion of the protocol in comparisons to concurrent anaerobic tests (WAnT, repeated running sprint ability, 140-m shuttle run in the basketball court) [ 5 , 17 ]. Meantime, it would be possible to advocate the use of the FVT an auxiliary tool to obtain the optimal load for a 30-s sprint as in the WAnT [ 14 ].…”

“…Although being classified as a promising test to assess short-term maximal intensity, the literature reporting data quality of the FVT is rather limited. A recent study [ 5 ] investigated the reproducibility of performance parameters obtained from 10-s maximal cycling effort against different Fb’s (4% to 11% of body mass) in young adult athletes (n = 48, males, aged 18.9–29.9 years) and concluded that reproducibility of measured PP tended to be acceptable and that within individual error was not related to Fb. The FVT provides a promising model for the investigation of short-term “all-out” assessment, but information about the reproducibility of optimal velocity, optimal Fb (OFb) and OPP was not abundant in the literature.…”

The current study aimed to examine the reproducibility of estimated peak power and estimated pedal velocity in a multi-trial 10-s all-out cycling test among adult athletes (n = 22; aged 23.50±4.73 years). Stature, sitting height and body mass were measured. Leg length was estimated as stature minus sitting height. Body volume was obtained from air displacement plethysmography and was subsequently used to calculate body density. Fat mass and fat-free mass were derived. The short-term power outputs were assessed from the force-velocity test (FVT), using a friction-braked ergometer on two separated occasions. Differences between repeated measurements were examined with paired t-test and effect sizes calculated. No significant differences were found between session 1 (898 W, 142 rpm) and session 2 (906 W, 142 rpm). Test-retest procedure showed acceptable reliability for estimated peak power output [technical error of measurement (TEM) = 31.9 W; % coefficient of variation (CV) = 3.5; intra-class correlation coefficient (ICC) = 0.986] and pedal velocity (TEM = 5.4 rpm, %CV = 3.8, ICC = 0.924). The current study demonstrated a reasonable reproducibility of estimated peak power and pedal velocity outputs in non-elite male athletes and supports that a familiarization session including a complete FVT protocol is not required.

A large number of power meters have become commercially available during the last decades to provide power output (PO) measurement. Some of these power meters were evaluated for validity in the literature. This study aimed to perform a review of the available literature on the validity of cycling power meters. PubMed, SPORTDiscus, and Google Scholar have been explored with PRISMA methodology. A total of 74 studies have been extracted for the reviewing process. Validity is a general quality of the measurement determined by the assessment of different metrological properties: Accuracy, sensitivity, repeatability, reproducibility, and robustness. Accuracy was most often studied from the metrological property (74 studies). Reproducibility was the second most studied (40 studies) property. Finally, repeatability, sensitivity, and robustness were considerably less studied with only 7, 5, and 5 studies, respectively. The SRM power meter is the most used as a gold standard in the studies. Moreover, the number of participants was very different among them, from 0 (when using a calibration rig) to 56 participants. The PO tested was up to 1700 W, whereas the pedalling cadence ranged between 40 and 180 rpm, including submaximal and maximal exercises. Other exercise conditions were tested, such as torque, position, temperature, and vibrations. This review provides some caveats and recommendations when testing the validity of a cycling power meter, including all of the metrological properties (accuracy, sensitivity, repeatability, reproducibility, and robustness) and some exercise conditions (PO range, sprint, pedalling cadence, torque, position, participant, temperature, vibration, and field test).
