This study is a double-blind, randomized, placebo-controlled trial designed to examine whether 8 weeks of Cistanche deserticola supplementation, when combined with a standardized anaerobic training program, can improve anaerobic exercise performance, recovery, and selected body composition outcomes in young adult men with different athletic training levels.
Participants will be assigned to receive either Cistanche deserticola extract or a matched placebo while completing the same supervised anaerobic training program. The study will assess changes in anaerobic performance, including Wingate test outcomes and jump performance, as well as recovery-related indicators such as blood lactate, creatine kinase, malondialdehyde, testosterone, cortisol, and the testosterone-to-cortisol ratio. Body composition outcomes, including body fat percentage and skeletal muscle mass, will also be evaluated.
The purpose of this study is to determine whether Cistanche deserticola supplementation provides additional benefits beyond training alone, and whether these effects differ between highly trained and recreationally trained participants.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cistanche Supplementation + Standardized Anaerobic Training | Experimental | Participants in this arm receive Cistanche deserticola extract paste (5 g/day) for 8 weeks while completing the same supervised standardized anaerobic training program as the control arm. The training program is performed 3 times per week and includes repeated sprint training, explosive/strength-support exercises, and short-bout high-intensity interval training. |
|
| Placebo + Standardized Anaerobic Training | Active Comparator | Participants in this arm receive a matched placebo for 8 weeks while completing the same supervised standardized anaerobic training program as the experimental arm. The placebo is matched in appearance, weight, texture, and taste. The training program is performed 3 times per week and includes repeated sprint training, explosive/strength-support exercises, and short-bout high-intensity interval training. |

| Cistanche deserticola | Dietary Supplement | Participants receive Cistanche deserticola extract paste at a dose of 5 g/day for 8 weeks. The supplement is administered in two sachets per day, one after breakfast and one after lunch. The product is derived from Cistanche deserticola Y.C. Ma cultivated in Inner Mongolia and consists primarily of phenylethanoid glycosides. Batch-specific quality-control documentation is provided by the supplier to ensure consistency. |

| Peak power during the 30-second Wingate Anaerobic Test | Peak power (W) measured during a 30-second Wingate Anaerobic Test performed on a Monark 894E cycle ergometer. The test is conducted under standardized conditions, and the primary analysis will evaluate the change from baseline to post-intervention and the between-group difference in change after 8 weeks of intervention. | Baseline (week 0) and post-intervention (week 8) |
| Squat jump height | Squat jump (SJ) height in centimeters, assessed under standardized testing conditions as a measure of lower-limb explosive performance. Analyses will assess change from baseline to post-intervention and between-group differences in change. | Baseline (week 0) and post-intervention (week 8) |
| Countermovement jump | Countermovement jump (CMJ) height in centimeters, assessed under standardized testing conditions as a measure of lower-limb explosive performance. Analyses will assess change from baseline to post-intervention and between-group differences in change. | Baseline (week 0) and post-intervention (week 8) |
| Measure | Description | Time Frame |
|---|---|---|
| Average power during the 30-second Wingate Anaerobic Test | Average power (W) measured during the 30-second Wingate Anaerobic Test. Analyses will assess change from baseline to post-intervention and between-group differences in change. | Baseline (week 0) and post-intervention (week 8) |
| Minimum power during the 30-second Wingate Anaerobic Test |
| Measure | Description | Time Frame |
|---|---|---|
| Body mass index | Body mass index (BMI, kg/m²) calculated from measured height and body weight. | Baseline (week 0) and post-intervention (week 8) |
| Body weight | Body weight (kg) measured under standardized fasting conditions. Analyses will assess change from baseline to post-intervention and between-group differences in change. |

Masking Description
|
| Matched placebo paste | Dietary Supplement | Participants receive a matched placebo for 8 weeks. The placebo is administered in two sachets per day, one after breakfast and one after lunch, following the same schedule as the experimental supplement. It contains maltodextrin, microcrystalline cellulose, caramel coloring, and a food-grade bittering agent, and is matched to the active supplement in appearance, weight, texture, and taste. |
|
| Standardized anaerobic training program | Behavioral | All participants complete the same supervised standardized anaerobic training program 3 times per week for 8 consecutive weeks. Each session lasts approximately 50 to 65 minutes and includes a dynamic warm-up, repeated sprint training, explosive/strength-support exercises, short-bout high-intensity interval training, and a cool-down. Training load is progressively increased across the intervention period, and attendance as well as session rating of perceived exertion are recorded throughout the study. |
