The influence of combined training sequence on adiposity indices in overweight women

This study examined whether the sequence of combined training (strength followed by endurance vs. endurance followed by strength) differentially affects adiposity- and metabolism-related indices in overweight and normal-weight women.

Sixty-six sedentary women, including overweight (n = 32; 25 ≤ BMI ≤ 30 kg/m²) and normal-weight (n = 34; 20 ≤ BMI ≤ 25 kg/m²), were randomly allocated to six groups: normal-weight S+E (n = 12), normal-weight E+S (n = 12), overweight S+E (n = 10), overweight E+S (n = 10), normal-weight control (n = 12), and overweight control (n = 10). Endurance training was performed on a cycle ergometer (60%-88% HRmax), and resistance training was conducted at 40%-75% of one-repetition maximum.

MANCOVA adjusted for baseline values revealed a significant main effect of group for adiposity- and metabolism-related indices, including AVI, BAI, TyG-WC, TyG-BMI, WHtR², McAuley index, CRI-I, and CRI-II (p < 0.05), with no effects of weight status or group × weight status interaction (p > 0.05). Post hoc analyses indicated both training groups (S+E and E+S) exhibited significantly improved values compared with the control for AVI, BAI, TyG-derived indices, and McAuley index (p < 0.05), with no differences between sequences. Limited sequence-dependent effects were observed for LAP, WHtR², and CRI-II, whereas no between-group differences were detected for CI, HOMA-IR, AIP, MOAD, VAI, or CRI-I.

Both combined training sequences resulted in significant changes in several adiposity- and metabolic-related indices compared with control, with sequence-specific differences evident for selected markers.
