Reliability of Force-Velocity Tests in Cycling and Cranking Exercises in Men and Women

Abstract

The present study examined the reliability of the force-velocity relationship during cycling and arm cranking exercises in active males and females. Twenty male and seventeen female physical education students performed three-session tests with legs and three-session tests with arms on a friction-loaded ergometer on six different sessions in a randomized order. The reliability of maximal power (P max), maximal pedal rate (V 0), and maximal force (F 0) were studied using the coefficient of variation (CV), the intraclass correlation coefficient (ICC) and the test-retest correlation coefficient (r). Reliability indices were better for men (1.74 ≤ CV ≤ 4.36, 0.82 ≤ ICC ≤ 0.97, and 0.81 ≤ r ≤ 0.97) compared with women (2.34 ≤ CV ≤ 7.04, 0.44 ≤ ICC ≤ 0.98, and 0.44 ≤ r ≤ 0.98) and in cycling exercise (1.74 ≤ CV ≤ 3.85, 0.88 ≤ ICC ≤ 0.98, and 0.90 ≤ r ≤ 0.98) compared with arm exercise (2.37 ≤ CV ≤ 7.04, 0.44 ≤ ICC ≤ 0.95, and 0.44 ≤ r ≤ 0.95). Furthermore, the reliability indices were high for P max and F 0 whatever the expression of the results (raw data or data related to body dimensions). P max and F 0 could be used in longitudinal physical fitness investigations. However, further studies are needed to judge V 0 reliability.

Smart Electrically Assisted Bicycles as Health Monitoring Systems: A Review

“…From general knowledge of the human body, it is well known that each person has their individual capabilities in both force and speed [114,115], leading to natural preferences during movements [116,117]. Moreover, the literature is well documented about the impact of strength limitations in cycling exercise within several populations, especially among those with diseases [118,119].…”

Force-velocity relationship of leg muscles assessed with motorized treadmill tests: Two-velocity method

“…Specifically, a manipulation of the external load provides a range of F and V data that allow for applying a linear regression model. Such results have been obtained from various maximum vertical jumps [4][5][6][7][8], cycling [9][10][11], leg press performed against various dynamometers and sledge devices [12][13][14], arm and upper body movements [6,10,11,15], or consistently across variety of tasks [16]. The particular advantage of the linear over the hyperbolic F-V relationship is that the obtained parameters directly reveal the maximum F (i.e., F-intercept), V (V-intercept), power (P; proportional to their product) producing capacities of the tested muscles, while the regression slope depicts the balance of the muscles' F and V producing capacities [13].…”

Isovelocity vs. Isoinertial Sprint Cycling Tests for Power- and Torque-cadence Relationships

“…Previous studies have made assessments of T-C and P-C relationships using different methods, which have been suggested as valid measures of T-C, P-C or PPO [2]. But each of these studies have only focused on one type of sprint cycling test [1,2,19,21]. Both isovelocity and isoinertial methods are suggested to be valid measures of T-C and P-C relationships.…”
