Motocross (MX) is a physically demanding sport with little research concerning the physiological characteristics of these athletes. The purpose of this study was to assess the anthropometric characteristics and performance capabilities of highly-trained MX athletes (n = 20; 19 ± 1.6yr) compared to age-matched physically active men (PA) (n = 22; 22 ± 2.9yr). Testing was performed on 2 occasions. The initial visit consisted of a personality assessment in addition to the following (in order): anthropometrics, body composition, anaerobic power/ fatigue, isokinetic/isometric strength and fatigue, and flexibility. The second visit consisted of peak oxygen uptake (VO2peak), handgrip strength, maximum pushups in 1 minute, extended arm hang time to exhaustion and 90° weighted wall-sit tests. All anthropometric and performance data were analyzed using independent samples t-tests to compare group means. Significance was set at p<0.05. Data are reported as mean ± SD. There were no significant differences between groups in anthropometric or body composition measurements except android fat (MX: 11.7 ± 1.9% vs. PA: 16.4 ± 8.4%, p = 0.04) and biceps circumference (MX: 30.1 ± 2.0 vs. PA: 33.1 ± 3.2cm, p = 0.001). MX had significantly higher absolute and relative mean anaerobic power (747.3 ± 63.7 vs. 679.7 ± 93.5W, p = 0.009 and 10.0 ± 0.6 vs. 9.2 ± 1.3W/kg, p = 0.002, respectively), relative anaerobic peak power (12.7 ± 0.8 vs. 11.9 ± 1.4W/kg, p = 0.029), time to exhaustion (TTE) (550.1 ± 70.6 vs. 470.1 ± 93.2s, p = 0.004), and extended arm hang duration (113.3 ± 44.9 vs. 73.4 ± 25.3s, p = 0.001). These results suggest highly-trained MX athletes possess certain physiological adaptations that likely result from sport-specific demands compared to PA.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 April 2026.
All research outputs
#12,387,738
of 34,575,175 outputs
Outputs from Journal of Strength & Conditioning Research
#4,750
of 7,449 outputs
Outputs of similar age
#150,938
of 444,275 outputs
Outputs of similar age from Journal of Strength & Conditioning Research
#98
of 128 outputs
Altmetric has tracked 34,575,175 research outputs across all sources so far. This one has received more attention than most of these and is in the 64th percentile.
So far Altmetric has tracked 7,449 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.2. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 444,275 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
We're also able to compare this research output to 128 others from the same source and published within six weeks on either side of this one. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
