Why LSTM better than Resnet50 for regression model

here I want to simulate a force plate using a smart insole. I compare 2 models, the 2 models I use are LSTM and resnet50. my experimental results show that LSTM has better results than Resnet50. but a paper explains that resnet50 is a comprehensive model. can anyone give a critical reason for this, "Why is LSTM better than resnet50 for this case?

SmartInsole.shape : (2000, 89)

SmartInsoleData: \[ 0., 0., 0., 13., 1., 0., 0., 0., 0., 0., 15., …
