Heavier loads (80% of 1RM) produce greater mean and matched integrated EMG muscle activation compared to lighter loads (50% of 1RM).

Practitioners should consider using heavier loads to enhance muscle activation during bench press exercises.

Low-load resistance exercise (50% of 1RM) results in greater total integrated EMG muscle activation compared to high-load resistance exercise (80% of 1RM).

Incorporating low-load exercises may enhance overall muscle activation in training programs.

Both traditional (TD) and pyramidal (PR) resistance training systems resulted in significant increases in muscular strength in older women, with TD showing a 12.4% increase in 1RM chest press and PR showing an 11.5% increase.

Both training systems can be effectively used to enhance strength in older female populations.

All training protocols significantly increased one repetition maximum (1RM) values post-training, with no significant differences between protocols.

Practitioners can expect similar strength gains across different rest intervals when volume is equalized.

Contrast training (CT) results in greater countermovement jump (CMJ) gains compared to resistance training (RT) with an effect size of 1.30.

Practitioners may consider incorporating contrast training to enhance vertical jump performance.

Contrast training (CT) shows higher countermovement jump (CMJ) performance compared to control groups with an effect size of 1.46.

Incorporating contrast training may lead to better jump performance compared to standard training.

Both pyramid (PR) and constant (CT) resistance training systems significantly improve muscular strength and muscle mass in resistance-trained older women.

Both training methods can be used effectively to enhance strength and muscle mass in older women.

Significant within-group increases in 1-RM bench press were observed for MJ, MJ + SJ, and SJ + MJ but not for SJ.

Varying the order of exercises can enhance strength gains in bench press.

Significantly greater increases in elbow extension 1-RM were noted for SJ, MJ + SJ, and SJ + MJ but not for MJ.

Single-joint exercises can be effective for improving elbow extension strength.

The greatest effectiveness of failure training occurs when practiced consistently over 6-week cycles, interspersed with non-failure training.

Implement structured training cycles for optimal results in hypertrophy.

A high-protein low-fat (HPLF) diet during short-term weight loss may be more effective at mitigating mood disturbance, fatigue, diet dissatisfaction, and stress than a moderate-protein moderate-fat (MPMF) diet.

Practitioners may consider recommending a high-protein low-fat diet for athletes aiming to lose weight while minimizing stress and fatigue.

Powerlifters can accurately select loads to reach a prescribed RPE.

Trainers can trust that powerlifters are capable of selecting appropriate loads based on RPE.

Accuracy for 8-repetition sets at 8 RPE may be better for bench press compared with squat.

Coaches may need to adjust load prescriptions differently for bench press and squat.

Squat power was closer to the target RPE in week 3 compared to week 1.

Progressive training may enhance load selection accuracy for squat over time.

Strategies like monitoring, action planning, and highlighting benefits can help clients stick to their resistance exercise program.

Implement these strategies to enhance client adherence to resistance exercise.

Significant improvements in absolute and relative peak power and mean power were found across various loads ranging from 45 to 75% 1RM (p = 0.006-0.041 for peak power, p = 0.001-0.032 for mean power).

Resistance-trained individuals can expect improvements in power with high-load training.

One-repetition maximum significantly increased for both bench press and squat after 8 weeks of low-load resistance training, regardless of rest interval.

Low-load training with either rest interval can effectively enhance strength in key lifts.

Attentional focus is important for maximizing muscular development.

Fitness professionals should consider how they direct attentional focus during training to enhance muscle development.

Muscle strength increased by a higher amount in the high-responsive group compared with the low-responsive group in the 45° leg press and bench press.

High responders to resistance training can expect greater improvements in muscle strength.

Low-load resistance training with blood flow restriction (LL-BFR) produces lower rating of perceived exertion (RPE) values (6.8 ± 1.1) compared to high-load resistance training (HL-RT) (8.1 ± 0.8) before training.

Practitioners may consider LL-BFR for clients seeking lower perceived exertion during workouts.

Muscle strength (1 repetition maximum) increased more in HL-RT (13.7 ± 5.9%) compared to LL-BFR (6.9 ± 4.1%).

For optimal strength gains, practitioners may prefer HL-RT over LL-BFR.

Maximal strength shows a significant effect of frequency with an increase in effect size of 0.14 for every day increase in frequency.

Increasing resistance training frequency may lead to greater improvements in maximal strength for older adults.

The athlete increased horizontal force (F H) in his weak leg by 26% after a targeted training program.

Targeted strength training can effectively increase force production in weaker limbs.

The athlete increased maximal velocity (v max) by 2% and power (P max) by 15% after the training program.

Targeted training can lead to measurable improvements in sprint performance metrics.
