Abstract
Gradient running (GR) has become popular as a form of training, due to the benefits it brings.
Tensiomyography (TMG) is a non-invasive method of assessing the contractile properties of a
muscle, but has not been used to study the effects of an acute bout of GR. This study aimed to
compare the effects of uphill running (UHR) and downhill running (DHR) against level
running (LR) using the TMG100 system. 12 male competitive athletes in running based sports
(Aged 24.8 ± 1.91) participated in this randomized crossover study. Participants were exposed
to LR in the first session and either UHR or DHR on the next two separate sessions, with
TMG variables (Tc, Dm, Tr, Ts and Td) being recorded at the start of the experiment and a
day after each session. Friedman’s ANOVA was performed and found that Td of the rectus
femoris (RF) was the only variable that differed statistically significantly (χ2 (3) = 13.10,
p=0.004). Mean RF Td values decreased by 2.05ms from Baseline (27.39 ±4.68) to UHR
(25.34 ±3.10), and decreased by 3.00ms and 4.35ms from LR (29.69±7.27) to DHR
(26.69±5.54) and UHR (25.34±3.10) respectively. Conover’s post hoc pairwise comparisons
found significant differences between RF Td between LR, DHR and UHR. The results of this
study suggest that LR is less fatiguing than UHR and DHR, which goes against existing
literature. Therefore, it is suggested that errors were made when conducting the experiment
and future studies are needed to reassess the effects of GR on TMG readings.
